F-1 ------------------------- ABOUT THIS PROSPECTUS You should only rely on the information contained in this prospectus. We have not authorized anyone to provide you with information different from that contained in this prospectus. We are offering to sell, and seeking offers to buy, shares of common stock only in jurisdictions where offers and sales are permitted. The information contained in this prospectus is accurate only as of the date of this prospectus, regardless of the time of delivery of this prospectus or of any sale of common stock. This preliminary prospectus is subject to completion prior to this offering. Among other things, this preliminary prospectus describes WESCO as we currently expect it to exist at the time of this offering. Certain persons participating in this offering may engage in transactions that stabilize, maintain or otherwise affect the price of the common stock, including stabilizing bids, syndicate covering transactions or the imposition of penalty bids. For a discussion of these activities, see "Underwriting." 1

4 PROSPECTUS SUMMARY This is only a summary and it does not contain all the information that may be important to you. In this prospectus, references to "we," "us," "our," and "WESCO" refer to WESCO International, Inc., and its subsidiaries and its predecessors. Unless we otherwise indicate, all information appearing in this prospectus gives effect to a to one stock split in the form of a stock dividend of our common stock to occur prior to the offering. You should read the following summary together with the more detailed information about WESCO and the common stock being sold in this offering and our historical and pro forma financial statements including the notes to those statements appearing elsewhere in this prospectus. OUR COMPANY With sales of over $3 billion in 1998, we are a leading North American distributor of electrical products and other industrial maintenance, repair and operating supplies, commonly referred to as MRO. We are the second largest distributor in the $72 billion U.S. electrical distribution industry. We are also the largest provider of integrated supply services in the United States. Our integrated supply solutions allow customers to reduce their operating costs through comprehensive outsourcing of all of their MRO procurement purchases through a single supplier with a highly automated process. We have over 330 branches and five distribution centers strategically located in 48 states, nine Canadian provinces, Puerto Rico, Guam, Mexico, the United Kingdom and Singapore. We serve over 130,000 customers worldwide, offering over 1,000,000 products from over 23,000 suppliers. Combining strong internal growth with acquisitions, our sales and income from operations plus depreciation, amortization and recapitalization costs, or EBITDA before recapitalization costs, increased at a compounded annual growth rate of over 16% and over 42%, respectively, since 1994. WESCO's earnings increased from a loss of $0.5 million in 1994 to $36.2 million in 1997. In 1998, we recorded a net loss of $7.7 million resulting from a $51.8 million one-time charge associated with our recapitalization. '94' 1636 '95' 1857 '96' 2275 '97' 2595 '98' 3025 '94' -1 30 '95' 17 63 '96' 32 79 '97' 36 91 '98' -8 123 - ------------------------- For information concerning sales, net income and EBITDA before recapitalization costs for 1994, see Notes 1 and 7 to "Selected Historical Consolidated Financial Data." EBITDA before recapitalization costs is presented since management believes that such information is considered by some investors to be a non-GAAP alternative basis for evaluating WESCO's ability to pay interest and repay debt. 2

5 We generate a significant amount of cash flow and require low capital investment to maintain our business. This significant cash flow is available to be used to enhance stockholder value by making acquisitions, reducing debt or repurchasing common stock. Our key management personnel are both operators and owners, many of whom have purchased significant equity positions over the past five years. Prior to the offering, over 220 of our executives and managers collectively held over 32% of our common stock on a fully diluted basis. None of our executives and managers will sell any shares of common stock in the offering. Our stock ownership and other incentive programs have closely aligned the interests of our managers with those of our stockholders. OUR BUSINESS STRATEGY Our objective is to be the leading distributor of electrical products and other MRO supplies and the leading provider of value-added related services to companies in North America and selected international markets. In achieving this leadership position, our goal is to grow earnings at a faster rate than sales by focusing on continuous productivity improvement. Our growth strategy leverages our existing strengths and focuses on developing new initiatives and programs to: - enhance our leadership position in electrical distribution; - grow national programs; - extend our leadership position in integrated supply; - gain share in key local markets; - actively pursue strategic acquisitions; - leverage our e-commerce and information system capabilities; - continue to improve profit margins; and - expand our international operations. OWNERSHIP Upon completion of this offering, management will own approximately 29% of our common stock on a fully diluted basis. The Cypress Group L.L.C. ("Cypress") will own approximately 35% of our common stock on a fully diluted basis. None of management, Cypress or its affiliates will sell any shares in the offering. Three of the seven members of our Board of Directors are affiliated with Cypress. Cypress is a private equity firm which currently manages over $3 billion of equity capital on behalf of major public and private pension funds, university endowments, trusts and other leading financial institutions. Cypress seeks to invest alongside experienced executives in growth businesses to achieve long-term capital appreciation. The Cypress professionals have successfully employed this strategy in numerous other investments such as Infinity Broadcasting Corporation, Lear Corporation, R.P. Scherer Corporation, Cinemark USA, Inc., Williams Scotsman, Inc. and Frank's Nursery & Crafts, Inc. RISK FACTORS See the section of this prospectus entitled "Risk Factors" for a discussion of factors that you should consider before investing in the common stock offered in this prospectus. These risk factors include competition, our substantial debt and related restrictions, growth strategy, our product supply, the importance of our information systems, our year 2000 compliance, our foreign operations, the significant influence of our controlling stockholders, the possible volatility in the price of our common stock, shares eligible for future sale, and anti-takeover provisions in our corporate documents. 3

6 THE OFFERING Common stock offered by WESCO: U.S. offering..................... 7,780,000 shares International offering............ 1,945,000 shares ---------- Total................ 9,725,000 Common stock outstanding after the offering.................................... 46,552,281 shares (1) Use of Proceeds............................. We intend to use net proceeds of $163.0 million from this offering to retire all of the outstanding 11 1/8% senior discount notes due 2008, to repay all of the existing indebtedness under our revolving credit facility, and the remaining balance to repay a portion of the Tranche B term loan. See "Use of Proceeds." Proposed NYSE Symbol........................ - ------------------------- (1) Based on 34,774,503 shares outstanding as of April 1, 1999, after giving effect to the 57.8 to one stock split in the form of a stock dividend and the conversion of certain outstanding notes in an aggregate principal amount of $37 million into 2,052,778 shares of common stock at the offering price. Currently, we also have authorized and issued Class B (non-voting) common stock, which is identical to the common stock except that it has no voting rights other than as required by law. The common stock to be outstanding after this offering also reflects the possible future conversion of outstanding shares of Class B common stock, at any time at the option of the holders, on a share for share basis into common stock and the termination concurrent with this offering of the rights of certain employee holders of common stock to require us under certain limited circumstances to repurchase all of their shares. See "Description of Capital Stock." 4

7 SUMMARY HISTORICAL AND PRO FORMA FINANCIAL DATA The following table sets forth summary historical consolidated financial data of WESCO as of and for the four years ended December 31, 1998, which have been derived from WESCO's audited financial statements. Our business was part of Westinghouse for the first two months of 1994. The results of operations and financial data for that period have been combined with the results of WESCO for the ten months ended December 31, 1994. For information concerning the period ended December 31, 1994, see Note 1 to the "Selected Historical Consolidated Financial Data." The following table also presents certain summary unaudited pro forma financial data of WESCO as of and for the year ended December 31, 1998, which have been derived from the "Unaudited Pro Forma Financial Information" and related notes included elsewhere in this prospectus. The summary unaudited pro forma income statement data give effect to the recapitalization, the acquisition of Bruckner and the offering as if they had occurred as of January 1, 1998. The summary unaudited pro forma balance sheet data give effect to the offering as if it occurred as of December 31, 1998. The summary unaudited pro forma financial data are provided for informational purposes only and do not purport to be indicative of the results that would have actually been obtained had the recapitalization, the acquisition of Bruckner and the offering been completed on the dates indicated or that may be expected to occur in the future. Pro forma results of the other acquisitions completed in 1998 are not included as they would not be materially different from the consolidated results presented. EBITDA before recapitalization costs represents income from operations plus depreciation, amortization and recapitalization costs. EBITDA before recapitalization costs is presented since management believes that such information is considered by certain investors to be an additional basis for evaluating WESCO's ability to pay interest and repay debt. EBITDA before recapitalization costs should not be considered an alternative to measures of operating performance as determined in accordance with generally accepted accounting principles or as a measure of WESCO's operating results and cash flows or as a measure of WESCO's liquidity. Since EBITDA before recapitalization costs is not calculated identically by all companies, the presentation herein may not be comparable to other similarly titled measures of other companies. Adjusted working capital is defined as trade accounts receivable plus inventory less accounts payable. Redeemable common stock is described in Note 11 to the Consolidated Financial Statements. Under certain limited circumstances, the holders of redeemable common stock have the right to require us to repurchase all of the redeemable shares and the exercisable portion of the options. These repurchase rights terminate upon consummation of the offering. The redemption value of the shares and exercisable portion of the options at December 31, 1998 was approximately $130.3 million. The summary historical and pro forma financial data should be read in conjunction with, and are qualified in their entirety by, the historical consolidated financial statements of WESCO and the notes thereto, "Selected Historical Consolidated Financial Data," "Management's Discussion and Analysis of Financial Condition and Results of Operations," and "Unaudited Pro Forma Financial Information," contained elsewhere in this prospectus. 5

9 - ------------------------- (1) Represents a one time charge related to the recapitalization, and primarily includes noncapitalized financing expenses, professional and legal fees and management compensation costs. Excluding the effects of this charge, net income would have been $30.6 million and diluted earnings per share would have been $ and pro forma net income would have been $36.3 million and pro forma diluted earnings per share would have been $0.74. (2) Represents costs relating to the sale of accounts receivable pursuant to the receivables facility. (3) Certain nondeductible recapitalization costs and other permanent differences significantly exceeded income before income taxes and resulted in an unusually high provision for income taxes. (4) Represents a charge, net of taxes, relating to the writeoff of unamortized debt issuance and other costs associated with the early extinguishment of debt. (5) For the year ended December 31, 1998, $1.3 million of the interest on convertible debt and common share equivalents have not been included, since the impact was anti-dilutive. (6) Reflects a 57.8 to one stock split effected in the form of a stock dividend of WESCO's common stock approved by the board of directors on , 1999 to be effective prior to consummation of the offering. (7) Excludes $274.2 million of accounts receivable pursuant to the sale in 1998 of such receivables in connection with the receivables facility. 7

10 RISK FACTORS You should carefully consider the following factors and other information contained in this prospectus in evaluating our business before deciding to invest in the shares of our common stock. AN INCREASE IN COMPETITION COULD ADVERSELY AFFECT OUR OPERATING RESULTS The distribution industry for electrical products and other industrial MRO supplies and services is very competitive. Competition is primarily focused on the local service area. We compete directly with national and regional broad-based companies, niche companies carrying only specialized products, and small, local companies with one or a few locations. Another source of competition in this industry is buying groups formed by smaller distributors to increase purchasing power and provide some cooperative marketing capability. Some of our existing competitors have, and new market entrants may have, greater financial and marketing resources than we do. To the extent existing or future competitors seek to gain or retain market share by reducing prices, we may be required to lower our prices, thereby adversely affecting financial results. OUR SUBSTANTIAL AMOUNT OF DEBT COULD LIMIT OUR GROWTH AND IMPOSES RESTRICTIONS ON OUR BUSINESS We have incurred substantial indebtedness. Our level of debt could adversely affect the interests of our stockholders, for example, by limiting our ability to: - use operating cash flow in other areas of our business since we must dedicate a substantial portion of these funds to pay interest and retire debt; - obtain additional financing to fund our growth strategy, capital expenditures and other purposes; and - react to changing market conditions and economic downturns. Before giving effect to this offering, we had $595.8 million of indebtedness as of December 31, 1998, and on a pro forma basis after giving effect to the use of net proceeds in this offering, we would have had $406.7 million of indebtedness. We may incur additional indebtedness in the future to fund our growth strategy and for general corporate purposes, subject to certain limitations contained in the instruments governing our indebtedness. Our debt agreements contain numerous financial and operating covenants that limit our discretion with respect to certain business matters. These covenants place significant restrictions on, among other things: - our ability to incur additional indebtedness; - to pay dividends and other distributions; - to repay our obligations; and - to merge or consolidate with other entities. SUCCESS OF OUR GROWTH STRATEGY MAY BE LIMITED BY THE AVAILABILITY OF APPROPRIATE ACQUISITIONS AND OUR ABILITY TO INTEGRATE ACQUIRED BUSINESSES INTO OURS A principal component of our strategy is to continue to expand through additional acquisitions that complement our operations in new or existing markets. Our acquisitions will involve risks, including the successful integration and management of acquired operations and personnel. The integration of acquired businesses may also lead to the loss of key employees of the acquired companies and diversion of management attention from ongoing business concerns. We may not be able to identify businesses that meet our strategic criteria and acquire them on satisfactory terms. We 8

11 also may not have access to sufficient capital to complete certain acquisitions. Future acquisitions may not prove advantageous and could have a material adverse effect on our operating results. LOSS OF KEY SUPPLIERS OR LACK OF PRODUCT AVAILABILITY COULD ADVERSELY AFFECT OUR BUSINESS Most of our agreements with suppliers are generally terminable by either party on no more than 60 days notice. Our ten largest suppliers in 1998 accounted for approximately 38% of our purchases for the period. Our largest supplier was Eaton Corporation, through its Cutler-Hammer division, accounting for approximately 15% of our purchases. The loss of, or a substantial decrease in the availability of, products from any of these suppliers, or the loss of key preferred supplier agreements, could have a material adverse effect on our business. In addition, supply interruptions could arise from shortages of raw materials, labor disputes or weather conditions affecting products or shipments, transportation disruptions or other reasons beyond our control. An interruption of operations at any of our five distribution centers could have a material adverse effect on the operations of branches served by the affected distribution center. Furthermore, we cannot assure that particular products, or product lines, will be available to us, or available in quantities sufficient to meet customer demand. This limited product access could put us at a competitive disadvantage. OUR SUCCESS IS DEPENDENT ON OUR INFORMATION SYSTEMS A serious disruption of our information systems could have a material adverse effect on our business and results of operations. Our computer systems are an integral part of our business and growth strategies. We depend on our information systems to process orders, manage inventory and accounts receivable collections, purchase products, ship products to our customers on a timely basis, maintain cost-effective operations and provide superior service to our customers. OUR SYSTEMS MAY NOT BE YEAR 2000 COMPLIANT The Year 2000 issue concerns the ability of automated applications to process date-dependent processes, calculations, and information by properly interpreting the year. With respect to WESCO, the Year 2000 issue may potentially impact business-critical computerized applications related to, among others, customer sales, service and invoicing, purchasing, inventory management, payroll, financing, and financial accounting and reporting. In addition, other non business-critical systems and services may also be affected. Year 2000 compliance has already been achieved in many systems. Other systems and processes critical to our business which are not Year 2000 compliant are either being replaced or corrected through program changes, application upgrades or replacement. We expect to have substantially completed required remediation efforts by July 1999. Our project team is also developing or enhancing contingency plans to minimize the potential adverse effect the Year 2000 issue could have on WESCO in the event business-critical systems and processes fail to be compliant. OUR FOREIGN OPERATIONS ARE SUBJECT TO POLITICAL AND ECONOMIC RISKS AND MAY BE ADVERSELY AFFECTED BY FOREIGN CURRENCY FLUCTUATIONS Although only 1% of our sales are presently realized outside of the United States and Canada, we believe substantial opportunities exist for us in other international markets. As our business activities increase in these markets, economic and political conditions of each local market may adversely affect our results of operations, cash flows and financial condition. Our results of operations and the value of our foreign assets are affected by fluctuations in foreign currency exchange rates, new and different legal, tax, accounting and regulatory requirements. 9

12 OUR CONTROLLING STOCKHOLDERS WILL OWN APPROXIMATELY 42% OF OUR COMMON STOCK AND CAN EXERCISE SIGNIFICANT INFLUENCE OVER OUR AFFAIRS After the offering, approximately 42% of the issued and outstanding shares of common stock will be held by Cypress and its affiliates. Accordingly, Cypress and its affiliates can exercise significant influence over our affairs, including the election of our directors, appointment of our management and approval of actions requiring the approval of our stockholders, including the adoption of amendments to our certificate of incorporation and approval of mergers or sales of substantially all of our assets. The voting power of these stockholders under certain circumstances could have the effect of delaying or preventing a change in control of WESCO. OUR COMMON STOCK HAS NEVER BEEN PUBLICLY TRADED AND THE PRICE OF OUR COMMON STOCK MAY FLUCTUATE SIGNIFICANTLY Prior to this offering, there has been no public market for our common stock. We will make an application for listing on the New York Stock Exchange. We do not know how the common stock will trade in the future. We determined the initial public offering price through negotiations with the underwriters. You may not be able to resell your shares at or above the initial offering price because the market price for shares of our common stock may fluctuate based on a number of factors including: - our operating performance and the performance of other similar companies; - news announcements relating to us, our industry or our competitors; - changes in earnings estimates or recommendations by research analysts; - changes in general economic conditions; - other developments affecting us, our industry, or our competitors; and - the stock market has experienced significant price and volume fluctuations in recent years, which are often unrelated to the operating performance of specific companies. A SUBSTANTIAL NUMBER OF SHARES WILL BE ELIGIBLE FOR FUTURE SALE BY OUR CURRENT STOCKHOLDERS, AND THE SALE OF THOSE SHARES COULD ADVERSELY AFFECT OUR STOCK PRICE Upon completion of the offering, our current stockholders and holders of options to acquire common stock, including our executive officers and directors and their affiliates, will own beneficially approximately % of the outstanding shares of our common stock and the rights to purchase an additional % of our outstanding common stock through the exercise of currently exercisable options ( %, if the underwriters' over-allotment option is exercised in full). After expiration of a 180-day "lock-up" period, these holders will in general be entitled to dispose of their shares. Sales of substantial amounts of our common stock, or the perception that such sales could occur at the expiration of such 180 day period, may materially adversely affect the prevailing market price of our common stock from time to time. PROVISIONS IN OUR CORPORATE DOCUMENTS COULD DELAY OR PREVENT A CHANGE IN CONTROL OF OUR COMPANY Our certificate of incorporation and bylaws contain several provisions which may have anti-takeover effects and may discourage, delay or prevent a takeover attempt that a stockholder might consider in his best interest. These provisions include the requirements that: - our board of directors will be classified into three classes with staggered terms; and - our board of directors will have the authority to authorize the issuance of preferred stock, which could adversely affect the voting and other rights of the holders of our common stock. 10

13 THIS PROSPECTUS CONTAINS FORWARD-LOOKING INFORMATION This prospectus contains forward-looking statements regarding our business. When used in this prospectus, the words "anticipates," "plans," "believes," "estimates," "intends," "expects," "projects" and similar expressions may identify forward-looking statements, although not all forward-looking statements contain such words. Such statements, including, but not limited to, our statements regarding business strategy, growth strategy, productivity and profitability enhancement, new product and service introductions and liquidity and capital resources are based on management's beliefs, as well as on assumptions made by, and information currently available to, management, and involve various risks and uncertainties, certain of which are beyond our control. Our actual results could differ materially from those expressed in any forward-looking statement made by or on our behalf. In light of these risks and uncertainties there can be no assurance that the forward-looking information will in fact prove to be accurate. Factors that might cause actual results to differ from such forward-looking statements include, but are not limited to, those discussed in "Risk Factors." 11

14 USE OF PROCEEDS Based on an assumed initial public offering price of $18.00 per share (the midpoint of the estimated range of initial public offering prices), we will receive approximately $163.0 million from the sale of shares of common stock in the offering after deduction of estimated underwriting discounts and commissions and estimated expenses (approximately $187.6 million if the underwriters' over- allotment option is exercised in full). We intend to use net proceeds of $59.7 million from the offering to retire all of the outstanding 11 1/8% senior discount notes due 2008 (of which $53.7 million will be applied to the principal amount of such notes and $6.0 million will be applied to a prepayment premium), $42.4 million to repay all of the existing indebtedness under the revolving credit facility, and the remaining balance to repay a portion of the Tranche B term loan. The senior discount notes were sold at a discount resulting in a yield to maturity of 11.175% per annum and will mature on June 1, 2008. As of December 31, 1998, the interest rate on the Tranche B term loan was 7.8% per annum, and the interest rate on borrowings under the revolving credit facility was 8.3% per annum. The revolving credit facility matures on June 5, 2004. The Tranche B term loan matures on June 5, 2006. WESCO used the proceeds of the revolving credit facility for general corporate purposes. WESCO used the proceeds of the Tranche B term loan and the proceeds of the issuance of senior discount notes to pay certain fees and expenses and to repay certain indebtedness in connection with the recapitalization. See Note 9 to Consolidated Financial Statements. DIVIDEND POLICY We have not paid or declared any dividends on our capital stock since our inception. We anticipate that, following the completion of the offering, earnings will be retained to support the growth of our business and will not be distributed to stockholders as dividends. The declaration and payment of any future dividends and the amount thereof will be determined by our board of directors and will depend upon our results of operations, financial condition, cash requirements, future prospects, limitations imposed by credit and debt agreements and other factors deemed relevant by our board of directors. See "Management's Discussion and Analysis of Financial Condition and Results of Operations -- Liquidity and Capital Resources." Pursuant to our credit and debt agreements, we may not declare or make, or agree to declare or make, directly or indirectly, any dividends, except that we may declare and pay dividends with respect to our capital stock payable solely in additional shares of our common stock or options, warrants or other rights to purchase our common stock. For further information concerning dividend restrictions, see Note 9 to the Consolidated Financial Statements. 12

15 CAPITALIZATION The following table sets forth our consolidated capitalization as of December 31, 1998. Our capitalization is presented on an actual basis and on a pro forma basis that gives effect to: - our 57.8 for one stock split effected in the form of a stock dividend and our sale of 9,725,000 shares of common stock in the offering at an assumed initial public offering price of $18.00 per share (the midpoint of the estimated range of initial public offering prices) after deducting estimated underwriting discounts and commissions and estimated offering expenses and the anticipated application of the net proceeds from the offering; and - the conversion of certain outstanding notes in the aggregate principal amount of $37 million and the termination of certain employees' rights to require WESCO to repurchase outstanding redeemable common stock.

16 DILUTION Our pro forma deficit in consolidated net tangible book value as of December 31, 1998 was $346.6 million or $(9.41) per share of our common stock. Pro forma deficit in consolidated net tangible book value per share represents the excess of total liabilities over total tangible assets adjusted for the conversion of certain outstanding notes in the aggregate principal amount of $37 million and the termination of certain employees' rights to require WESCO to repurchase outstanding redeemable common stock divided by the adjusted number of shares of common stock outstanding. After giving effect to the sale of the shares of our common stock in the offering (at an assumed initial offering price of $18 per share) and before deducting anticipated offering expenses and underwriting discounts and commissions, our adjusted pro forma deficit in consolidated net tangible book value as of December 31, 1998 would have been $171.6 million or $(3.69) per share, representing an immediate $21.69 per share dilution to new investors purchasing shares at the initial public offering price. The following table illustrates such per share dilution. Assumed initial public offering price per share............. $ 18.00 ------- Pro forma deficit in consolidated net tangible book value per share as of December 31, 1998......................... $ (9.41) ------- Increase per share attributable to new investors.......... $ 5.72 ------- Deficit in consolidated net tangible book value per share after the Offering........................................ $ (3.69) ------- Dilution per share to new investors......................... $ 21.69 ======= The following table sets forth, on a pro forma basis as of December 31, 1998, the number of shares of common stock purchased from WESCO, the total consideration paid and the average price per share paid by existing stockholders and by new investors (assuming the sale by WESCO of shares in the offering at an assumed initial public offering price of $18 per share), before deduction of underwriting discounts and commissions and offering expenses (dollars in thousands): SHARES PURCHASED TOTAL CONSIDERATION --------------------- ------------------- PERCENT PERCENT AVERAGE AFTER AFTER PRICE NUMBER OFFERING AMOUNT OFFERING PER SHARE ---------- -------- -------- -------- --------- Existing stockholders(1).......... 36,817,628 79.1% $377,030 68.3% $10.24 ---------- ----- -------- ----- ------ New stockholders.................. 9,725,000 20.9 175,050 31.7 18.00 ---------- ----- -------- ----- ------ Total........................ 46,542,628 100.0% $552,080 100.0% ========== ===== ======== ===== - ------------------------- (1) Includes shares issuable upon the conversion of certain outstanding notes in the aggregate principal amount of $37 million. The foregoing tables assume no exercise of any outstanding stock options or the underwriters' over-allotment options. As of December 31, 1998, there were outstanding options to purchase shares of common stock at a weighted average exercise price of approximately $ per share. To the extent that the outstanding options, or any options granted in the future, are exercised, there will be further dilution to new investors. 14

17 UNAUDITED PRO FORMA FINANCIAL INFORMATION The following unaudited pro forma financial information of WESCO has been prepared to give effect to the acquisition of Bruckner, the recapitalization and the offering. We treated the recapitalization as a leveraged recapitalization for financial reporting purposes; accordingly, the historical basis of our assets and liabilities was not affected by the transaction. For a discussion of the recapitalization, see "Management's Discussion and Analysis of Financial Condition and Results of Operations -- Recent Developments." The pro forma adjustments presented are based upon available information and include certain assumptions and adjustments that we believe are reasonable under the circumstances. These adjustments are directly attributable to the transactions referenced above and are expected to have a continuing impact on our business, results of operations and financial condition. Our historical condensed consolidated balance sheet as of December 31, 1998 and the statement of operations for the year ended December 31, 1998 were derived from our Consolidated Financial Statements included elsewhere herein. Our unaudited pro forma condensed consolidated balance sheet gives effect to the offering as if it had occurred on December 31, 1998. Our unaudited pro forma condensed consolidated statement of operations for the year ended December 31, 1998 gives effect to the acquisition of Bruckner, the recapitalization and the offering as if they occurred on January 1, 1998. The historical financial data of Bruckner for the period January 1, 1998 to September 11, 1998 (the acquisition date) was derived from its unaudited financial statements. The acquisition of Bruckner was accounted for using the purchase method of accounting pursuant to which the total purchase price was allocated to the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values. None of the acquisitions described in the prospectus, excluding Bruckner, met the individual or aggregate criteria outlined by the SEC's significant subsidiary test. The unaudited pro forma financial information and related notes thereto are provided for informational purposes only. They do not necessarily reflect our results of operations or financial condition that would have actually resulted had the events referred to above or in the notes to the unaudited pro forma financial information been consummated. In addition, the unaudited pro forma financial information is not intended to project our financial condition or results of operations for any future period and does not necessarily reflect the effect of an extraordinary charge of $9.6 million expected to result from the offering related to the early extinguishment of outstanding 11 1/8% senior discount notes and a portion of the credit facilities. 15

21 WESCO INTERNATIONAL, INC. NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED STATEMENT OF OPERATIONS (DOLLARS IN THOUSANDS) (1) Reflects Bruckner historical financial data for the period January 1, 1998 to September 11, 1998 (the acquisition date). Certain reclassifications have been made to Bruckner's historical financial statements to conform to the presentation used by WESCO upon completion of the acquisition. (2) Reflects incremental amortization of goodwill resulting from the acquisition of Bruckner over an estimated period of 35 years. (3) Reflects incremental interest expense on new obligations related to the acquisition of Bruckner. The obligations consist of $19,000 of new borrowings and a non-interest bearing convertible note due March 31, 2000 and discounted to a value of $26,621 for financial reporting purposes (face value $30,000). The assumed interest rate on the $19,000 of new borrowings under WESCO's existing credit agreement was 8.3%. For purposes of this pro forma financial information, the original issue discount on the non-interest bearing convertible note is accreted on a straight-line basis (which approximates the effective interest method) over the period ending March 31, 2000. Assuming a 0.125 percentage point change in interest rates, interest expense would change by $24 for the year ended December 31, 1998. (4) Reflects the income tax effect of converting Bruckner from a subchapter S corporation to a C corporation and the income tax effects of the pro forma adjustments at an assumed rate of 39%. (5) Reflects the elimination of non-recurring advisory, management consulting and monitoring fees paid to WESCO's investors prior to the recapitalization during the periods presented. Historical revenue and expenses would not have been materially changed without these services. (6) Reflects the incremental interest expense relating to the recapitalization assuming interest rates of 9 1/8% for the senior subordinated notes, 7.60% for the Tranche A term loan and 7.75% for the Tranche B term loan borrowings under a new credit agreement, and amortization of original issue and purchase discounts, as well as the incremental amortization expense resulting from the capitalization of transaction fees and expenses of $10,570 related to the recapitalization. The amortization of debt issuance costs was $1,355 for the year ended December 31, 1998. The senior discount notes were issued with an original issue discount of $36,522. The original issue discount is being accreted over the period ending June 1, 2003. Assuming a 0.125 percentage point change in interest rates, interest expense would change by $213 for the year ended December 31, 1998. (7) Reflects the incremental costs related to the sale of certain accounts receivable in connection with the recapitalization at an assumed discount rate of 6.19%. (8) Reflects the elimination of interest expense and the elimination of amortization of original issue and purchase discounts with the repayment of senior discount notes, revolving credit facility borrowings and a portion of Tranche B term loan as follows: AMORTIZATION ACCRETION OF INTEREST DISCOUNTS EXPENSE TOTAL ------------- -------- ------- Senior discount notes....................................... $5,801 $ 5,801 Revolving credit facility................................... $3,131 3,131 Tranche B term loan......................................... 4,674 4,674 Acquisition notes........................................... 2,175 561 2,736 ------ ------ ------- $7,976 $8,366 $16,342 ====== ====== ======= In addition, amortization of debt issuance costs totaling $278 associated with the above debt were eliminated. (9) Includes a one-time charge primarily related to the noncapitalized financing expenses, professional and legal expenses and management compensation costs. Assuming such charges were not incurred, pro forma net income would have been $36,310 and pro forma diluted earnings per share would have been $0.74. (10) Excludes interest on convertible debt of $1,266 for Historical and As Adjusted and and 3,266,844 common share equivalents for Historical and As Adjusted, respectively, as the inclusion would be anti-dilutive. (11) Reflects a 57.8 to one stock split effected in the form of a stock dividend of WESCO's common stock approved by the board of directors on , 1999 to be effective prior to the consummation of the offering. 19

22 SELECTED HISTORICAL CONSOLIDATED FINANCIAL DATA The following table sets forth selected historical consolidated financial data of WESCO as of and for the four years ended December 31, 1998 which have been derived from audited financial statements. The period ended December 31, 1994 represents the combined financial data of our predecessor, Westinghouse Electric Supply Company, a division of Westinghouse, for the two months ended February 28, 1994 and of WESCO for the ten months ended December 31, 1994. The combined selected data do not purport to represent what WESCO's consolidated results of operations would have been if the acquisition had actually occurred on January 1, 1994. The selected historical consolidated financial data of WESCO as of December 31, 1997 and 1998 and for the three years ended December 31, 1998 have been derived from our consolidated financial statements included elsewhere herein, which have been audited by PricewaterhouseCoopers LLP. The selected historical consolidated financial data should be read in conjunction with, and is qualified in its entirety by, our historical consolidated financial statements and the accompanying notes thereto and "Management's Discussion and Analysis of Financial Condition and Results of Operations" included elsewhere in this prospectus. 20

(11.5) 63.7 -- Net cash used for investing activities........................... 0.1 (256.6) -- Net cash provided by financing activities........................... 11.9 197.5 -- (i) Presents consolidated financial data of our predecessor, the Westinghouse Electric Supply Company, a division of Westinghouse, for the periods prior to WESCO's acquisition of substantially all of the assets and certain liabilities of our predecessor, effective February 28, 1994. Consolidated financial data of our predecessor have been derived from our predecessor's consolidated financial statements, which have been audited by our predecessor's accountants. The Commission, in Staff Accounting Bulletin Number 55 (SAB 55), requires that historical financial statements of a subsidiary, division or lesser business component of another entity include certain expenses incurred by the parent on its behalf. These expenses include officer and employee salaries; rent; depreciation; advertising; accounting and legal services; other selling, general and administrative expenses; and other such expenses. The financial statements of our predecessor include such adjustments, estimates or allocations as the management of our predecessor's parent company believed necessary to reflect these expenses. Because of such items, certain aspects of the consolidated results of operations for periods prior to the period beginning February 28, 1994 are not comparable with those for subsequent periods. (ii) Presents combined results of operations of our predecessor for the two months ended February 28, 1994 and of WESCO for ten months ended December 31, 1994. The combined operations data does not purport to represent what WESCO's consolidated results of operations would have been if the acquisition had actually occurred on January 1, 1994. (iii) Our predecessor received a charge from its parent company in the form of interest expense for the portion of the parent company investment that, for internal reporting purposes, represented debt. For the two months ended February 28, 1994, approximately 40% of the average parent company investment was considered to be debt for internal reporting purposes. The effective annual interest rates for all periods was approximately 10%. This 22

25 method of reporting interest expense for internal reporting purposes is not necessarily indicative of interest expense that would have been incurred had our predecessor operated as a separate stand-alone entity. (iv) Our predecessor's results of domestic operations were included in the consolidated U.S. federal income tax return of Westinghouse. The income tax expense and other tax-related information in our predecessor's consolidated financial statements were calculated as if our predecessor had not been eligible to be included in the consolidated tax returns of Westinghouse (i.e., on a "stand-alone" basis). The calculation of tax provisions and deferred taxes necessarily required certain assumptions, allocations and estimates that our predecessor's management believed were reasonable to accurately reflect the tax reporting for our predecessor as if a stand-alone taxpayer. (2) Represents a one-time charge primarily related to noncapitalized financing expenses, professional and legal fees and management compensation costs. Reference is made to Note 1 to "Prospectus Summary -- Summary Historical and Pro Forma Financial Data" and "Management's Discussion and Analysis of Financial Condition and Results of Operations -- Results of Operations -- 1998 compared to 1997." (3) Represents costs relating to the sale of accounts receivable pursuant to the receivables facility. (4) Certain nondeductible recapitalization costs and other permanent differences significantly exceeded income before income taxes and resulted in an unusually high provision for income taxes. (5) Represents a charge, net of taxes, relating to the write-off of unamortized debt issuance and other costs associated with the early extinguishment of debt. (6) For a description of the calculation of basic and diluted earnings per common share, see Notes 2 and 13 to Consolidated Financial Statements included elsewhere in this prospectus. For the year ended December 31, 1998, $1.3 million of the interest on convertible debt and common share equivalents have not been included, since the impact was anti-dilutive. (7) EBITDA before recapitalization costs represents income from operations plus depreciation, amortization and recapitalization costs. EBITDA before recapitalization costs is presented since management believes that such information is considered by certain investors to be an additional basis for evaluating WESCO's ability to pay interest and repay debt. EBITDA before recapitalization costs should not be considered an alternative to measures of operating performance as determined in accordance with generally accepted accounting principles or as a measure of WESCO's operating results and cash flows or as a measure of WESCO's liquidity. Since EBITDA before recapitalization costs is not calculated identically by all companies, the presentation herein may not be comparable to other similarly titled measures of other companies. (8) Defined as trade accounts receivable plus inventories less accounts payable. (9) Excludes $274.2 million of accounts receivable pursuant to the sale in 1998 of such receivables in connection with the receivables facility. (10) Represents redeemable common stock as described in Note 11 to Consolidated Financial Statements. Under certain limited circumstances, the holders thereof have the right to require us to repurchase all of the redeemable shares and the exercisable portion of the options. These repurchase rights terminate upon consummation of the offering. The redemption value of the shares and exercisable portion of the options at December 31, 1997 and 1998 was approximately $68.6 million and $130.3 million, respectively. See "Certain Relationships and Related Transactions -- Management Stockholders." 23

26 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS The following discussion should be read in conjunction with the audited consolidated financial statements and notes thereto included elsewhere in this prospectus. GENERAL WESCO is a leading distributor of electrical products and other industrial MRO supplies and the leading provider of value-added related services in North America. WESCO has over 330 branches and five distribution centers strategically located in 48 states, nine Canadian provinces, Puerto Rico, Guam, Mexico, the United Kingdom and Singapore. WESCO serves over 130,000 customers worldwide, offering over 1,000,000 products from over 23,000 suppliers. WESCO's diverse customer base includes a wide variety of industrial companies; contractors for industrial, commercial, and residential projects; utility companies; and commercial, institutional and governmental customers. Approximately 90% of WESCO's net sales are generated from operations in the U.S., 9% from Canada and the remainder from other countries. WESCO's sales can be categorized as stock, direct ship and special orders. Stock orders are filled directly from existing inventory and generally represent 40% to 50% of total sales. Approximately 35% to 45% of WESCO's total sales are direct ship sales. Direct ship sales are typically custom-built products, large orders or products that are too bulky to be easily handled and, as a result, are shipped directly to the customer from the supplier. Special orders are for products that are not ordinarily stocked in inventory and are ordered based on a customer's specific request. Special orders represent the remainder of total sales. Gross profit margins on stock and special order sales are approximately 50% higher than those on direct ship sales. Although direct ship gross margins are lower, operating profit margins are often higher, since the product handling and fulfillment costs associated with direct shipments are much lower. WESCO continues to emphasize a number of initiatives designed to improve its working capital performance, primarily in the area of inventory management. Such initiatives include: - coordinating purchasing and inventory investment activities among groups of branches or "districts;" - upgrading the automated stock replenishment programs used to supply branches from the distribution centers; - negotiating improved inventory return and consignment arrangements with suppliers; - increasing the use of preferred suppliers; and - shortening lead times between order and delivery from suppliers. WESCO has historically financed its acquisitions, new branch openings, working capital needs and capital expenditures through internally generated cash flow and borrowings under its credit facilities. During the initial phase of an acquisition or new branch opening, WESCO typically incurs expenses related to installing or converting information systems, training employees and other initial operating activities. With some acquisitions, WESCO may incur expenses in connection with the closure of any of its own redundant branches. Historically, the costs associated with opening new branches, and closing branches in connection with certain acquisitions, have not been material. WESCO has accounted for its acquisitions under the purchase method of accounting. WESCO is the leading consolidator in its industry, having acquired 18 companies since August 1995 representing annual sales of over $1.1 billion. Management distinguishes sales attributable to core operations separate from sales of acquired businesses. The distinction between sales from core 24

27 operations and from acquired businesses is based on WESCO's internal records and on management estimates where the integration of acquired businesses results in the closing or consolidation of branches. RECENT DEVELOPMENTS The recent results of operations and financial position of WESCO were affected by the following: Recapitalization. On June 5, 1998, WESCO repurchased and retired all of its common stock, with the exception of certain shares held by members of management, for an aggregate consideration of approximately $654 million and repaid approximately $379 million of the then outstanding indebtedness. In connection with the transaction, WESCO also sold 89% of its common stock to an investor group led by affiliates of Cypress for an aggregate cash consideration of $318 million, issued $300 million of senior subordinated notes and approximately $50 million of senior discount notes, borrowed $170 million under a new credit facility and sold approximately $250 million of accounts receivable as part of an off-balance sheet securitization transaction. Following the recapitalization, management's retained ownership interest amounted to 11% of the common stock. Acquisitions. During 1998, WESCO completed six acquisitions with total annual sales exceeding $600 million for an aggregate purchase price of $250 million. The most significant acquisition, Bruckner, a provider of integrated supply procurement services for large industrial companies, was completed in September 1998. Bruckner had annual sales of approximately $222 million in 1997. The purchase price paid at closing was $99.1 million, consisting of $72.5 million in cash and a convertible note discounted to a value of $26.6 million. RESULTS OF OPERATIONS The following table sets forth the percentage relationship to net sales of certain items in WESCO's Consolidated Statements of Operations for the periods presented: YEAR ENDED DECEMBER 31, ----------------------- 1996 1997 1998 ----- ----- ----- Sales, net.................................................. 100.0% 100.0% 100.0% Gross profit................................................ 17.8 17.9 17.8 Selling, general and administrative expenses................ 14.3 14.3 13.7 Depreciation and amortization............................... 0.5 0.5 0.5 Recapitalization costs...................................... -- -- 1.7 ----- ----- ----- Income from operations................................. 3.0 3.1 1.9 Interest expense............................................ 0.8 0.8 1.6 Other expense............................................... -- -- 0.3 ----- ----- ----- Income before income taxes............................. 2.2 2.3 -- Income taxes................................................ 0.8 0.9 0.3 ----- ----- ----- Net income (loss)...................................... 1.4% 1.4% (0.3)% ===== ===== ===== 1998 Compared to 1997 Net Sales. Sales in 1998 increased $430.6 million, or 16.6%, to $3,025.4 million compared with $2,594.8 million for 1997. Sales from core operations increased approximately 4% with the balance of the sales increase coming from eight acquisitions since the beginning of 1997. The mix of direct shipment sales increased to approximately 42% in 1998 from 39% in 1997 as a result of the Bruckner acquisition. Substantially all of Bruckner's sales are direct shipment. Consistent with recent trends, branches with a high volume of sales to utility customers experienced somewhat higher levels of sales 25

28 growth. Also, the Canadian branches recorded sales growth of 4% in 1998 in Canadian currency and when translated to U.S. dollars, those sales declined 3%. Gross Profit. Gross profit for the year ended December 31, 1998 increased $73.7 million to $537.6 million from $463.9 million for 1997. Gross profit margin declined slightly to 17.8% in 1998 from 17.9% in 1997. This decrease resulted from a higher proportion of direct ship sales attributable to the Bruckner acquisition. Direct ship gross margins are lower than those of other sales; however, operating profit margins are often higher, since the product handling and fulfillment costs associated with direct shipments are much lower. Excluding the effects of the Bruckner acquisition, the 1998 gross profit margin increased to 18.1%. WESCO believes that this increase in gross margin is the result of numerous gross margin improvement initiatives. Selling, General and Administrative Expenses. Selling, general and administrative ("SG&A") expenses increased $42.5 million, or 11.4%, to $415.0 million. The majority of this increase was associated with companies acquired during 1998; the remainder of the increase was associated with certain expenses that are variable in nature and increase when sales increase. As a percent of sales, SG&A expenses declined to 13.7% compared with 14.3% a year ago, reflecting cost containment initiatives in the core business representing a 0.4% decrease as a percent of sales, and the effects of a lower cost structure associated with the Bruckner acquisition. Depreciation and Amortization. Depreciation and amortization increased $3.5 million to $14.8 million reflecting higher amortization of goodwill from acquisitions and increases in property, buildings and equipment over the prior year. Recapitalization Costs. During 1998, WESCO completed the recapitalization and incurred one-time costs associated with this transaction amounting to $51.8 million. These costs are related to noncapitalized financing expenses, professional and legal fees and management compensation costs. Interest and Other Expense. Interest expense totaled $45.1 million, an increase of $25.0 million over 1997. The increase was primarily due to the higher levels of borrowings associated with acquisitions and the recapitalization. Other expense totaled $10.1 million in 1998 reflecting costs associated with the accounts receivable securitization. Income Taxes. Income tax expense totaled $8.5 million in 1998 compared with $23.8 million in 1997. In 1998 WESCO recorded $51.8 million of costs associated with the recapitalization which contributed to income before taxes of $0.8 million. Certain nondeductible recapitalization costs and other permanent differences significantly exceeded the $0.8 million of income before taxes and resulted in an unusually high effective tax rate. The effective tax rate in 1997 was 39.6%. Net Income (Loss). Net loss and diluted loss per share totaled $7.7 million and $9.93 per share, respectively, for 1998, compared with net income and diluted earnings per share of $36.2 million and $31.52 per share, respectively, for 1997. The comparability of the results was affected by the one-time charge of $51.8 million related to the recapitalization, the impact of the nondeductibility of a portion of these costs on taxes and an increase in interest expense associated with higher debt levels, as a result of the recapitalization and acquisitions. Excluding the recapitalization costs of $51.8 million, net income for 1998 would have been approximately $30.6 million. 1997 Compared to 1996 Net Sales. Sales in 1997 increased $320.2 million, or 14.1%, to $2,594.8 million, compared with $2,274.6 million for 1996. Sales from core operations increased approximately 7%. Within the U.S., the branches with a high volume of sales to utility customers experienced a somewhat higher level of sales growth. In addition to growth from core operations, the remaining sales increase resulted from the nine companies acquired since the beginning of 1996. Sales of product from stock rose 21%, as compared to the prior period, increasing the mix of stock sales three percentage points to 48% of total 26

29 sales. This was a result of several ongoing initiatives designed to increase stock sales, such as the continued emphasis on growing National Accounts sales, and, to a lesser extent, the impact of acquired company sales, which have tended to have a higher mix of stock sales. Direct ship sales rose 4% over the prior period. This sales increase was below that experienced by WESCO in other areas and was primarily due to the slower growth in the non-residential construction market for commercial and industrial projects, which constitutes the majority of direct ship sales. Gross Profit. Gross profit in 1997 totaled $463.9 million compared with $405.0 million in 1996. The increase of $58.9 million, or 14.5%, was due to higher sales volume in 1997 from both acquisitions and existing operations. Gross profit margin increased in the comparison to 17.9% from 17.8%. In 1996, gross profit of approximately $9.3 million was recorded in connection with a one-time international construction project with a gross profit margin that was higher than WESCO's usual margins on similar projects due to the service requirements and risk considerations associated with the order. Excluding this project, gross profit margins would have been 17.9% and 17.6% in 1997 and 1996, respectively. The increase in gross profit margin was due to the increase in the mix of higher margin stock sales including sales associated with acquired companies. Selling, General and Administrative Expenses. SG&A expenses increased $46.5 million, or 14.3%, to $372.5 million and was primarily attributable to companies acquired since the beginning of 1996. As a percent of net sales, SG&A expenses remained unchanged at 14.3%. Acquisitions with higher SG&A expense rates were partially offset by cost containment in WESCO's core business, as well as cost reductions in acquired companies. Interest and Other Expenses. Interest expense increased by $2.7 million in 1997 to $20.1 million from $17.4 million in the prior year. This increase is due to the higher levels of borrowings associated with acquisitions and increased working capital to support sales growth, partially offset by lower interest rates during 1997. Income Taxes. The effective tax rate was 39.6% for 1997 compared to 36.1% for 1996. The increase in the effective tax rate was due to the reduction of a valuation allowance for deferred tax assets in 1995 and 1996, which had the effect of reducing the income tax rate during those periods. WESCO began its operations as a stand-alone entity in early 1994 with no history of generating taxable income. Accordingly, a valuation allowance was established for the net deferred tax assets that were generated during 1994. In 1995 and 1996, as WESCO subsequently demonstrated an ability to utilize such deferred tax assets, the valuation allowance was reduced and had the effect of reducing the effective tax rate for both 1995 and 1996. Since the valuation allowance was eliminated during 1996, there was no similar effect on the 1997 tax rate. Net Income. Net income and diluted earnings per share totaled $36.2 million and $31.52 per share, respectively, for 1997, compared with $32.5 million and $29.47 per share in 1996. The earnings increase was due to an increase in gross profit partially offset by higher operating expenses and a higher effective tax rate in the comparison. LIQUIDITY AND CAPITAL RESOURCES Total assets were $950.5 million at December 31, 1998 and $870.9 million a year earlier. In addition, stockholders' equity was a deficit of $142.6 million at December 31, 1998 compared with total stockholders' equity of $184.5 million at December 31, 1997. The changes in these categories, as well as long-term debt discussed below, reflect the effects of the sale and repurchase of common stock, debt refinancing and sale of accounts receivable completed in connection with the recapitalization. 27

30 Primarily as a result of the recapitalization completed in June 1998, WESCO has increased its debt as set forth below: DECEMBER 31 ---------------- 1997 1998 ------ ------ (IN MILLIONS) Term loans.................................................. $ -- $169.5 Revolving credit facility................................... -- 42.4 Old revolving credit facility............................... 226.2 -- Senior subordinated notes (1)............................... -- 289.2 Senior discount notes (2)................................... -- 52.1 Mortgage notes (3).......................................... 65.3 -- Other....................................................... 3.7 42.6 ------ ------ 295.2 595.8 Less current portion........................................ (1.0) (16.6) ------ ------ $294.2 $579.2 ====== ====== - ------------------------- (1) Net of original issue discount of $0.9 million and purchase discount of $9.9 million. (2) Net of original issue discount of $33.2 million and purchase discount of $1.7 million. (3) Net of original issue discount of $16.6 million. The term loans and revolving facility borrowings are made pursuant to a credit agreement. The credit agreement provides for three term loan facilities consisting of Tranche A term loan, Tranche B term loan and a delayed draw term facility, as well as a $100 million revolving credit facility. Tranche A term loan provides for borrowings of $80 million, Tranche B term loan provides for borrowings of $90 million and the delayed draw facility provides for borrowings of up to $100 million. Borrowings under the credit agreement bear rates of interest equal to various indices, at WESCO's option, such as an adjusted LIBOR, prime rate or the Federal Funds rate, plus a borrowing margin. The revolving credit facility and the Tranche A term loan matures in 2004. The delayed draw term facility matures in 2005 and the Tranche B term loan matures in 2006. All term loans provide for amortizations of principal payments prior to maturity. The senior subordinated notes issued by WESCO Distribution have an aggregate principal amount of $300 million. The senior subordinated notes bear interest at 9 1/8%, payable semiannually on June 1 and December 1 of each year. The notes are due June 1, 2008 and are redeemable at the option of WESCO, in whole or in part, at any time after June 1, 2003 at certain specified prices. Prior to June 1, 2001, up to $105 million of the notes may be redeemed at 109.125% in connection with any offering of WESCO's equity securities. The senior discount notes have an aggregate principal amount of $87 million. The notes were issued with an original issue discount of $36.5 million that is being accreted over the period ending June 1, 2003. Beginning June 1, 2003, interest accrues at 11 1/8% payable semiannually on June 1 and December 1. Approximately $30.9 million of the notes must be redeemed on June 1, 2003. The remaining notes are due June 1, 2008 and are redeemable at the option of WESCO, in whole or in part, at any time after June 1, 2003 at certain specified prices. Prior to June 1, 2001, the notes may be redeemed in certain specified instances at 111.125%. The debt agreements contain various restrictive covenants that, among other things, impose limitations on: - dividend payments or certain other restricted payments or investments; - the incurrence of additional indebtedness and guarantees or issuance of additional stock; 28

31 - creation of liens; - mergers, consolidation or sales of substantially all of WESCO's assets; - certain transactions among affiliates; - payments by certain subsidiaries to WESCO; and - capital expenditures. In addition, the agreements require WESCO to meet certain leverage, working capital and interest coverage ratios. See "Description of Certain Indebtedness." Aggregate principal repayment requirements for all indebtedness as of December 31, 1998 are $16.9 million, $40.7 million, $13.1 million, $16.5 million and $51.4 million in each of the next five years. An analysis of cash flows for 1998 and 1997 follows: Operating Activities. For the year ended December 31, 1998, cash provided by operating activities totaled $276.9 million compared to cash used by operating activities of $12.0 million for 1997. In connection with WESCO's asset securitization program, cash provided by operations in 1998 included proceeds of $274.2 million from the sale of accounts receivable. Excluding this transaction, operating activities provided $2.7 million. On this basis, the year-to-year variance in operating cash flow was primarily due to a net loss of $7.7 million, the $16.9 million increase in certain components of net working capital offset by increases in non-cash costs associated with the recapitalization, depreciation, amortization and accretion. Investing Activities. Net cash used in investing activities was $184.1 million in 1998, compared to $21.5 million in 1997, primarily reflecting an increase of $160.1 million in investments in businesses acquired in the current period. WESCO's capital expenditures for the year ended December 31, 1998 were $10.7 million as compared to $11.6 million for the year ended December 31, 1997. Such capital expenditures were primarily for computer equipment and software, telecommunications equipment, branch and distribution center facility improvements, forklifts and delivery vehicles. Financing Activities. Cash used for financing activities totaled $92.3 million for year ended December 31, 1998 compared to $41.1 million provided by financing activities in 1997, primarily reflecting the recapitalization completed in June 1998 and borrowings for acquisitions and other general business purposes. WESCO's liquidity needs arise from seasonal working capital requirements, capital expenditures, debt service obligations and acquisitions. In addition, with the acquisition of Bruckner, WESCO agreed to pay additional contingent consideration based on a multiple of annual increases in Bruckner's EBITDA through 2004. Additional contingent payments will not exceed an aggregate of $130 million, including $30 million which is payable in July, 1999. After the offering, at the election of Bruckner, up to 50% of any additional contingent payment is convertible into common stock at its then market value. In addition to cash generated from operations and amounts available under the credit facilities, WESCO entered into a receivables facility which provides liquidity. Pursuant to the receivables facility, WESCO through its wholly-owned special purpose, bankruptcy-remote subsidiary may sell trade accounts receivables, on a revolving basis up to $300 million. WESCO may, under certain circumstances, increase the size of the receivables facility when the amount of eligible trade accounts receivables exceeds $300 million. See Note 4 to Consolidated Financial Statements. After the Offering. WESCO intends to use the net proceeds of the offering to retire all of the outstanding 11 1/8% senior discount notes due 2008 (of which $53.7 million will be applied to the 29

32 principal amount of such notes and $6.0 million will be applied to a prepayment premium), $42.4 million to repay all of the existing indebtedness under the revolving credit facility, and the remaining balance to repay a portion of the Tranche B term loan. See "Capitalization" and "Use of Proceeds." Following the offering, WESCO will have $100 million available under the revolving credit facility, under its current provisions, for working capital and other corporate purposes and up to $100 million available under the delayed draw term facility to fund acquisitions. In addition, WESCO intends to seek modifications of its credit agreement to increase the amounts available to borrow on more favorable terms and conditions. WESCO can give no assurance that it will be able to negotiate acceptable modifications to the credit agreement. Management believes that cash generated from operations, together with amounts available under the credit agreement after the offering and the receivables facility, will be sufficient to meet WESCO's working capital, capital expenditure and other cash needs for the next three years. There can be no assurance, however, that this will be the case. Financing of acquisitions can be funded under the existing credit agreement and may, depending on the number and size of acquisitions, require the issuance of additional debt and equity securities. YEAR 2000 READINESS DISCLOSURE The Year 2000 issue concerns the ability of automated applications to process date-dependent processes, calculations and information by properly interpreting the year. The Year 2000 issue may potentially impact WESCO's business-critical computerized applications related to, among others, customer sales, service and invoicing, purchasing, inventory management, payroll, financing and financial accounting and reporting. In addition, other non business-critical systems and services may also be affected. WESCO has assembled an internal project team composed of information systems, operations, finance and executive personnel to: - assess the readiness of our systems, vendors and suppliers, third-party service providers, customers and financial institutions; - replace or correct through program changes all non-compliant applications; - develop remediation action plans for systems that may not be Year 2000 compliant; and - develop contingency plans in the event systems and services are not compliant. The readiness assessment phase of the project is complete and consisted of a detailed assessment and testing of substantially all internal computer systems, surveys of significant vendors and suppliers, service providers and customers. WESCO has received, or is seeking, documentation from many external parties, including its major suppliers, customers and service providers, indicating their Year 2000 readiness. Over the past three years, WESCO has invested approximately $5.5 million in new information systems to support the growth and diversity of its business. In addition to meeting this objective, Year 2000 compliance was also achieved in many systems. Systems and processes critical to our business that remain non-compliant are either being replaced or corrected through program changes and application upgrades. As of the date of this prospectus, many of WESCO's information technology and non-information technology systems are Year 2000 compliant, and management expects to have substantially completed the required remediation efforts by July 1999. The project team is also developing or enhancing contingency plans to minimize the potential adverse effect the Year 2000 issue could have on WESCO in the event business-critical systems and processes of WESCO or its suppliers or customers fail to be compliant. Such contingent plans include identifying alternative suppliers or service providers. Costs specifically associated with modifying WESCO's systems for Year 2000 compliance are expensed as incurred. Through December 31, 1998, such costs totaled approximately $1.1 million. Costs to be incurred in 1999 to address Year 2000 problems are estimated to be $2.3 million. Such costs do not include normal system upgrades and replacements. 30

33 Based on current information, WESCO believes that the most likely worst case scenario to result from a Year 2000 failure by WESCO, its suppliers or customers would be a temporary limitation in its ability to distribute electrical products from certain operating locations or provide integrated supply services to its customers. Based on its own efforts and information received from third parties, WESCO does not believe that Year 2000 issues are likely to result in significant operational problems or have a material adverse impact on its consolidated financial position, operations or cash flow. Nonetheless, failures of suppliers, third party vendors or customers resulting from Year 2000 issues could result in a short-term material adverse effect. INFLATION The rate of inflation, as measured by changes in the consumer price index, did not have a material effect on the sales or operating results of WESCO during the periods presented. However, inflation in the future could affect WESCO's operating costs. Price changes from suppliers have historically been consistent with inflation and have not had a material impact on WESCO's results of operations. However, during 1998 WESCO experienced price reductions on certain of its products, particularly wire and cable. These price declines did not have a material effect on WESCO's results of operations. SEASONALITY WESCO's operating results are affected by certain seasonal factors. Sales are typically at their lowest during the first quarter due to a reduced level of activity during the winter months. Sales increase during the warmer months beginning in March and continuing through November. Sales drop again slightly in December as the weather cools and also as a result of reduced level of activity during the holiday season. As a result, WESCO reports sales and earnings in the first quarter that are generally lower than that of the remaining quarters. The following table presents unaudited quarterly operating results for each of WESCO's last eight quarters as well as the percentage of WESCO's sales represented by each item. This information has been prepared by WESCO on a basis consistent with WESCO's audited financial statements and includes all adjustments (consisting only of normal recurring adjustments) that management considers necessary for a fair presentation of the data. These quarterly results are not necessarily indicative of future results of operations. This information should be read in conjunction with WESCO's consolidated financial statements and notes thereto included elsewhere in this prospectus.

34 IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS In April 1998, the American Institute of Certified Public Accountants issued Statement of Position 98-5, "Reporting on the Costs of Start-Up Activities." This Statement, which is effective for fiscal years beginning after December 15, 1998, requires costs incurred to open a new facility, introduce a new product, commence a new operation or other similar activities to be expensed as incurred. Management does not expect this Statement will have a material impact on the results of operations or financial position of WESCO. In June 1998, The Financial Accounting Standards Board issued SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities." This Statement is effective in fiscal years beginning after June 15, 1999, although early adoption is permitted. This Statement requires the recognition of the fair value of any derivative financial instrument on the balance sheet. Changes in fair value of the derivative and, in certain instances, changes in the fair value of an underlying hedged asset or liability, are recognized through either income or as a component of other comprehensive income. Management does not expect this Statement will have a material impact on the results of operation or financial position of WESCO. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKS The information required to be furnished relative to market risk has not been included as it is not material to WESCO. 32

35 OUR BUSINESS OVERVIEW With sales of over $3 billion in 1998, we are a leading North American distributor of electrical products and other industrial MRO supplies. We are the second largest distributor in the $72 billion U.S. electrical distribution industry, which has grown at a compounded annual rate of 7% over the last 15 years. We have capitalized on our leadership position in electrical distribution to become the largest provider of integrated supply services in the United States. Our integrated supply solutions allow customers to reduce their operating costs through comprehensive outsourcing of all of their industrial MRO procurement purchases through a single supplier with a highly automated process. Demand for integrated supply services has increased approximately 90% annually since 1994, and the total U.S. market potential, measured as all purchases of industrial MRO supplies and services, is estimated to be $250 billion. We have over 330 branches and five distribution centers strategically located in 48 states, nine Canadian provinces, Puerto Rico, Guam, Mexico, the United Kingdom and Singapore. We serve over 130,000 customers worldwide, offering over 1,000,000 products from over 23,000 suppliers. Our diverse customer base includes a wide variety of industrial companies; contractors for industrial, commercial, and residential projects; utility companies; and commercial, institutional and governmental customers. We are the leading consolidator in our industry, having acquired 18 companies since August 1995, representing annual sales of over $1.1 billion. Combining strong internal growth with acquisitions, our sales and EBITDA before recapitalization costs increased at a compounded annual growth rate of over 16% and over 42%, respectively, since 1994. WESCO's earnings increased from a loss of $0.5 million in 1994 to $36.2 million in 1997. In 1998, we recorded a net loss of $7.7 million resulting from a $51.8 million one-time charge associated with our recapitalization. To achieve this substantial growth in sales and profitability, our management team has realigned operations and successfully implemented strategic initiatives which we believe have: - significantly expanded our national marketing programs; - established us as the leader in providing integrated supply services; - organized our operations to focus on key customer markets; - positioned us as the industry's leading consolidator; - significantly improved gross margins, reduced operating costs and increased return on assets; - utilized proprietary information technology to reduce costs, streamline operations and better serve customers; - established new performance-based incentive systems for branch managers and sales personnel; and - promoted broad-based employee participation in common stock ownership and stock option programs. Our customers choose WESCO because of our ability to manage large, complex multi-site plant maintenance programs and procurement for projects that require special sourcing, technical advice, logistical support and locally based service. Our national programs - including integrated supply, National Accounts and Major Projects - meet our customers' growing needs to reduce costs throughout their supply chain. These needs include value-added procurement solutions and uniformity of service throughout many locations, a single point of contact and coordinated pricing and project management. Our national programs enable customers to reduce material and labor costs, working capital investments, administration and redundant processes while increasing reliability, quality, productivity and other efficiencies. Since a customer's costs of procuring MRO supplies can be over 50% of the cost of the products, the opportunity for savings is significant. 33

36 INDUSTRY OVERVIEW Electrical Distribution With 1998 sales estimated at $72 billion, the U.S. industry is large and growing. The industry is also stable with compounded annual growth of 7% since 1982, and it is projected to grow another 7% in 1999. The following chart illustrates the historical growth and relative stability of the electrical distribution industry: '1982' 24.6 - ------ ---- '1983' 26.6 '1984' 29.5 '1985' 32.7 '1986' 34.0 '1987' 36.1 '1988' 35.9 '1989' 39.0 '1990' 39.6 '1991' 38.1 '1992' 39.7 '1993' 45.6 '1994' 51.1 '1995' 56.7 '1996' 61.4 '1997' 67.3 '1998' 72.9 '1999' 77.6 Source: Electrical Wholesaling Magazine The U.S. electrical distribution industry is also highly fragmented. In 1997, the latest year for which data is available, the four national distributors, including WESCO, accounted for less than 15% of estimated total industry sales. BALANCE OF TOP 250 FULL- 4 NATIONAL CHAINS 10 MULTI-REGIONAL CHAINS LINE DISTRIBUTORS 4,200+ ALL OTHER DISTRIBUTORS - ----------------- ------------------------ ------------------------ ----------------------------- 14.7 5.80 23.90 55.60 Source: Electrical Wholesaling Magazine The electrical distribution industry serves customers in the industrial, commercial, construction and utility markets. The distribution channel enables customers to more efficiently purchase a broad 34

37 range of products and services from a single point of contact and eliminates the costs and complexity of purchasing directly from many manufacturers. As a result, distributors have approximately doubled their share of total electrical products sold in the U.S. from 1972 to 1998, with sales by distributors representing approximately 60% of the U.S. electrical market in 1997. In addition to sourcing electrical products, many customers also seek logistical and technical services from those distributors able to package a wide range of products and services. Increasingly, customers are seeking distributors that provide an even broader and more comprehensive package of products and services, such as integrated supply, as customers outsource non-core functions and strive to reduce their cost of purchasing, inventory and supply chain management. Integrated Supply Demand for integrated supply services is growing rapidly, as more companies realize they can lower costs by outsourcing their MRO procurement and related services. The total market for MRO industrial supplies is approximately $250 billion, based on published industry sources. The following chart reflects the historical and projected annual growth of integrated supply services within that market: '1994' 0.7 - ------ --- '1995' 2.00 '1996' 3.30 '1997' 5.00 '2000' 11.00 Source: Frank Lynn & Associates, Inc. 1998 Study Companies with integrated supply capabilities seek to consolidate all of a customer's MRO procurement requirements into a single automated process. Features of an integrated supply arrangement usually include a combination of one or more of the following: - consolidated billing across multiple locations; - product standardization; - inventory item reductions; - order entry systems simplification; - vendor managed inventory and - storeroom management. 35

38 Integrated supply services enable customers to reduce labor costs, working capital investments, administration and redundant processes while increasing reliability, quality, productivity and other efficiencies. Since the customers' costs of procuring MRO supplies can be over 50% of the cost of the products, such improvements can be significant. OUR BUSINESS STRATEGY Our objective is to be the leading distributor of electrical products and other MRO supplies and the leading provider of value-added related services to companies in North America and selected international markets. In achieving this leadership position, our goal is to grow earnings at a faster rate than sales by focusing on continuous productivity improvement. Our growth strategy leverages our existing strengths and focuses on developing new initiatives and programs. ENHANCE OUR LEADERSHIP POSITION IN ELECTRICAL DISTRIBUTION. We intend to leverage our extensive market presence and brand equity in the WESCO name to further our leadership position in electrical distribution. We are the second largest electrical distributor in the U.S. and, through our value-added products and services, we believe we have become the industry leader in serving several important and growing markets including: - industrial customers with large, complex plant maintenance operations, some of which require a national multi-site service solution for their electrical distribution product needs; - large contractors for major industrial and commercial construction projects; - the electric utility industry; and - manufacturers of factory-built homes, recreational vehicles and other modular structures. GROW NATIONAL PROGRAMS. Since 1994, revenue from our National Accounts program has increased in excess of 20% annually. Through our National Accounts program, we coordinate electrical MRO procurement and purchasing activities primarily for large industrial companies across multiple locations. We have well established relationships with over 300 companies, providing us with a recurring base of revenue through multi-year agreements. We believe that we can continue to increase revenue generated through our National Accounts program by: - increasing sales to existing National Account customers through new products, more services and additional locations; - extending established National Account relationships to include integrated supply; - expanding our customer base by leveraging our existing expertise and presence within the automotive, petrochemical, pulp and paper and metals and mining industries; and - entering new industries such as multi-site retail, financial, commercial and telecommunications. In addition, through our Major Projects Group, we plan to intensify our focus on large projects such as industrial sites, water treatment plants, airport expansions, healthcare facilities, correctional institutions and new sports stadiums. We intend to secure new Major Projects contracts through: - aggressive national marketing of our demonstrated project management capabilities; - further development of relationships with leading contractors and engineering firms; - close coordination with National Accounts customers on their renovation and new plant improvement projects; and - comprehensive materials management services, involving a multi-commodity integrated supply approach to large projects. EXTEND OUR LEADERSHIP POSITION IN INTEGRATED SUPPLY. We are the largest provider of integrated supply services for MRO goods and services in the United States. We provide a full complement of outsourcing solutions, focusing on improving the supply chain management process for our customers' indirect purchases. Our integrated supply programs replace the traditional multi-vendor, resource- 36

39 intensive procurement process with a single, outsourced, fully automated process capable of managing all MRO and related service requirements. Our solutions range from just-in-time product delivery to taking over the entire procurement function. Our customers include some of the largest industrial companies in the United States. Competitive strengths of our integrated supply business include: - a proven and profitable business model highly adaptable to the scale of our customers' operations; - low operating costs; - highly automated proprietary information systems; and - established relationships with a large industrial customer base. We intend to utilize these competitive strengths to increase our integrated supply sales to both new and existing customers, including our existing National Account customers. GAIN SHARE IN KEY LOCAL MARKETS. Significant opportunities exist to gain local market share, since many local markets are highly fragmented. We intend to increase our market share in key geographic markets through a combination of increased sales and marketing efforts at existing branches, acquisitions to expand our product and customer base and new branch openings. Furthermore, we intend to leverage our existing relationships with preferred suppliers to increase sales of their products in local markets through various initiatives, including sales promotions, cooperative marketing efforts, direct participation by suppliers in National Accounts implementation, dedicated sales forces and product exclusivity. To promote growth, we have instituted a compensation system for branch managers based on profit increases and efficient working capital management at the branch level. Our compensation system encourages our branch managers to optimize business activities in their local markets, including managing the sales force, configuring inventories, targeting potential customers for marketing efforts and tailoring local service options. ACTIVELY PURSUE STRATEGIC ACQUISITIONS. We are the industry's leading consolidator. We believe that the highly fragmented nature of the electrical and industrial MRO distribution industry will provide us with a significant number of acquisition opportunities. We utilize a disciplined approach toward acquisitions which includes well defined strategic criteria and established targets for return on investment and earnings accretion. EXPAND PRODUCT AND SERVICE OFFERINGS. We intend to build on our demonstrated ability to introduce new products and services to meet customer demands and capitalize on market opportunities. For example, we will continue expanding our presence in the fast-growing data communications market. We have significantly increased our focus on this market, generating sales of almost $100 million in 1998, up from $52 million in 1995. By utilizing a dedicated data communications sales team and training our existing sales force to sell data communications products, we intend to increase sales to new and existing customers. In addition, through a recent acquisition, we now have a platform to sell integrated lighting control and power distribution equipment in a single package for multi-site specialty retailers, restaurant chains and department stores. This is a well defined and attractive growth market where our marketing programs and logistics infrastructure provide measurable benefits for renovation, new construction and ongoing maintenance activities. LEVERAGE OUR e-COMMERCE AND INFORMATION SYSTEM CAPABILITIES. We conduct a significant amount of business electronically and continue to invest in information technology to create tighter linkages with both customers and suppliers and to lower costs and shorten cycle time in the supply chain process for our customers and ourselves by: - conducting business transactions electronically; we routinely process customer orders, shipping notices, supplier purchase orders, and funds transfer electronically with our trading partners; in our integrated supply business, 95% of all transactions are electronic; 37

40 - creating tighter linkages to both customers and suppliers through the use of technological advances, including an ability to order over the Internet and through CD-ROM catalogs, bar-coding, and electronic funds transfer; - providing low cost, highly functional processing of a full-range of our business operations such as customer service, inventory, logistics management, accounting and administrative support; and - analyzing market potential, sales performance and cost of doing business by branch, customer, product, sales representative and shipment type enabling us to work with customers to streamline activities and reduce costs. CONTINUE TO IMPROVE PROFIT MARGINS. We have more than doubled our profit margins since 1994 and are committed to seeking continuous improvement in productivity and profitability. We use innovative and disciplined techniques to manage our business processes, employee productivity and return on capital. These initiatives include: - using performance-based, branch level incentive programs to promote profitable growth; - employing more disciplined and sophisticated pricing strategies; - expanding use of information technology to continuously monitor operations and enhance decision making in order to streamline activities and reduce costs; - utilizing activity-based costing to accurately measure profitability by branch, salesperson and customer; - improving inventory management among suppliers, branches and regional distribution centers; and - improving sales productivity through sales management and training programs. LOWER OPERATING COSTS. Through our national scale, use of technology, quality of our information management capabilities, strategically located distribution centers and over 100 separate ISO 9002 quality certifications, we operate with one of the lowest cost structures in our industry. We will utilize our low cost advantage to continue to offer our customers competitive pricing while improving our overall profitability. Our low operating costs make it possible to fund strategic marketing initiatives and also make it difficult for less efficient competitors to match our combination of pricing and ability to service a wide range of customers on a profitable basis. EXPAND OUR INTERNATIONAL OPERATIONS. Our international sales, the majority of which are in Canada, accounted for 10% of sales in 1998. We believe that there is significant additional demand for our products and services outside the U.S. and Canada. Many of our multinational domestic customers are seeking distribution, integrated supply and project management solutions globally. Our approach to international operations is consistent with our domestic philosophy. We follow our established customers and will only pursue business that we believe utilizes and extends our existing capabilities. This strategy of working through well-developed customer and supplier relationships reduces risks and provides the opportunity to establish a profitable business. In 1998 we opened two branch locations in Mexico, which are growing and profitable, and we recently opened sales offices in London, Scotland and Singapore. PROMOTE PERFORMANCE-ORIENTED CULTURE. All named executives, as well as many other managers purchased significant equity positions over the past five years. These investments represent a significant portion of their personal net worth. Prior to the offering, over 220 of our executives and managers collectively held approximately 32% of our common stock on a fully diluted basis. None of our executives and managers will sell any shares of common stock in the offering. Our stock ownership programs and other incentive systems have closely aligned the interests of the managers with those of our stockholders. Our performance based stock option programs are directly linked to margin expansion and operating profit growth objectives. 38

41 ACQUISITION AND INTEGRATION PROGRAM Our philosophy towards growth includes a continuous evaluation to determine whether a particular opportunity, capability, or customer need is best developed internally or purchased through a strategic acquisition. We evaluate potential acquisitions, including those in the electrical distribution industry, the integrated supply market and other non-electrical distributors that would complement our customers' overall supply needs. We have completed 18 acquisitions representing total annual sales of over $1.1 billion. In addition, we have recently signed a letter of intent to acquire a northeastern electrical distributor with annual sales of approximately $22 million, subject to final contract negotiations and regulatory approval. WESCO ACQUISITION HISTORY (DOLLARS IN MILLIONS) YEAR ACQUISITIONS BRANCH LOCATIONS ANNUAL SALES(1) - ---- ------------ ---------------- ---------------- 1995...................... 2 2 $ 47 1996...................... 7 67 418 1997...................... 2 9 52 1998...................... 6 21 608 1999 to date.............. 1 3 25 -- --- ------ Total:............... 18 102 $1,150 --------------------------------- (1) Represents our estimate of annual sales of acquired businesses at the time of acquisition, based on our review of internal and/or audited statements of the acquired business. Our business development department consists of a dedicated team of professionals who locate, evaluate, and negotiate all aspects of any acquisition, with particular emphasis on compatibility of management philosophy and strategic fit. Since 1995 we have considered over 250 potential acquisitions. We initially evaluate potential acquisitions based on their ability to: - better serve our existing customers; - offer expansion into key growth markets; - add new product or service capabilities; - support new National Account customers; and - strengthen relationships with important manufacturers. If a potential acquisition meets our strategic objectives, we then perform a rigorous financial and operational evaluation of the candidate. We adhere strictly to our acquisition criteria, which include targeted returns on investment, net income accretion and first year cash flow objectives. Retention of key management has always been an important element in our transaction structure. Upon completing an acquisition, we strive to rapidly integrate the acquired business into our existing operations. Our focus is to fully understand the capabilities, strategic opportunities and needs of our new business partners, shorten the transition period to the extent feasible, maintain the acquired organization's stability, bolster the organization to better serve the defined market, adjust incentive programs, assure profitability and closely monitor sales and customer service. We believe that our disciplined integration process offers a number of opportunities to improve productivity and customer service, consolidate purchasing power and reduce operating costs. PRODUCTS AND SERVICES PRODUCTS. Our network of branches and distribution centers stock over 215,000 products. Each branch tailors its inventory to meet the needs of the customers in its local market, typically stocking 39

42 approximately 4,000 to 8,000 products. Our integrated supply business allows our customers to access over 1,000,000 products for direct shipment. Representative products that we sell include: - Supplies: Fuses, terminals, connectors, boxes, fittings, tools, lugs, tape and other MRO supplies - Distribution Equipment: Circuit breakers, transformers, switchboards, panelboards and busway - Lighting: Lamps (light bulbs), fixtures and ballasts - Wire and Conduit: Wire, cable, metallic and non-metallic conduit - Control, Automation and Motors: Motor control devices, drives, programmable logic controllers, pushbuttons and operator interfaces - Data Communications: Premise wiring, patch panels, terminals, connectors We purchase products from a diverse group of over 23,000 suppliers. In 1998, the ten largest suppliers accounted for approximately 38% of our purchases. The largest of these was Eaton Corporation, through its Cutler-Hammer division, accounting for approximately 15% of total purchases. No other supplier accounted for more than 6%. Our supplier relationships are strategically important to us, providing access to a wide range of products, technical training and sales and marketing support. We have preferred supplier agreements with approximately 150 of our suppliers and purchase approximately 60% of our stock inventory pursuant to these agreements. Consistent with industry practice, most of our agreements with suppliers, including both distribution agreements and preferred supplier agreements, are terminable by either party on no more than 60 days notice. See "Risk Factors -- Loss of Key Preferred Supplier Arrangements or Lack of Product Availability Could Adversely Affect Our Business." SERVICES. In conjunction with product sales, we offer customers a wide range of services and procurement solutions that draw on our product and supply management expertise and systems capabilities. These services include National Accounts programs, integrated supply programs and Major Project programs. We are responding aggressively to the needs of our customers, particularly those in processing and manufacturing industries. To more efficiently manage the MRO process on behalf of our customers, we offer a range of supply management services, including: - outsourcing of the entire MRO purchasing process; - providing manufacturing process improvements using state-of-the-art automated solutions; - implementing inventory optimization programs; - participating in joint cost savings teams; - assigning our employees as on-site support personnel; - recommending energy-efficient product upgrades; and - offering safety and product training for customer employees. National Accounts Programs. The typical National Accounts customer is a Fortune 500 industrial company, a large utility or other major customer, in each case with multiple locations. Recently, through rigorous selection processes, these customers have been seeking to substantially reduce their electrical supply base -- in some cases from several hundred suppliers to just one -- with expectations for documented cost reductions, high levels of service and consistent product and pricing across all locations. Our national platform, strong branch network and product breadth give us the capacity to offer multi-site agreements with the scope required by these customers. Our National Accounts programs provide customers with total supply chain cost reductions by coordinating purchasing activity for MRO supplies across multiple locations. We typically are able to demonstrate documented savings of over 10% within the first year of program launch. Comprehensive implementation plans establish jointly-managed teams at the local and national level to prioritize activities, identify key performance measures and track progress against objectives. We involve our 40

43 preferred suppliers early in the implementation process, where they can contribute expertise and product knowledge to accelerate program implementation and the achievement of cost savings and process improvements. Integrated Supply Programs. Our integrated supply programs offer customers a variety of services to support their objectives for improved supply chain management. We integrate our personnel, product and distribution expertise, electronic technologies and service capabilities with the customer's own internal resources to meet particular service requirements. Each integrated supply program is uniquely configured to deliver a significant reduction in the number of MRO suppliers, reduce total procurement costs, improve operating controls and lower administrative expenses. Our solutions range from just-in-time fulfillment to taking over the entire procurement function for all indirect purchases. We believe that customers will increasingly seek to utilize us as an "integrator," responsible for selecting and managing the supply of a wide range of MRO and direct material products. Major Projects. We are one of the industry leaders in serving the complex needs of large commercial and industrial contractors. We have established a Major Projects Group, comprised of our most experienced personnel, which focuses on the top 50 U.S. electrical contractors on a multi-regional basis. These contractors typically specialize in building industrial sites, water treatment plants, airport expansions, healthcare facilities, correctional institutions and new sports stadiums. MARKETS AND CUSTOMERS We have a large base of approximately 130,000 customers diversified across our principal markets. With no customer accounting for more than 3% of 1998 sales, we are not dependent on any single customer. INDUSTRIAL CUSTOMERS. Sales to industrial customers accounted for approximately 40% of our sales in 1998, while representing approximately 32% of the electrical distribution market in 1997. MRO products are needed to maintain and upgrade the electrical and communications networks at all industrial sites. Expenditures are greatest in the heavy process industries, such as pulp and paper and petrochemical. Typically, electrical MRO is the first or second ranked product category by purchase value for total MRO requirements for an industrial site. Other MRO product categories include, among other things, lubricants; pipe, valves and fittings; fasteners; and power transmission products. MRO activity has been difficult and costly for industrial users to manage, as it is characterized by a fragmented supplier base, a high volume of low dollar transactions, poor usage and cost information and relatively high inventory levels. For example, it is not unusual for a customer to inventory as many as 10,000 MRO products. Furthermore, customers are sensitive to supply reliability, since a lack of critical spares could cause an entire manufacturing process to shut down. Certain manufacturing customers incorporate electrical components and assemblies into their own products, which are commonly referred to as original equipment manufacturers or OEMs. Original equipment manufacturers typically require a reliable, high volume supply of a narrow range of electrical items. Customers in this segment are particularly service and price sensitive due to the volume and the critical nature of the product used, and they also expect value-added services such as design and technical support, just-in-time supply and electronic commerce. Long term customer relationships are common and lead to an efficient supply process and stable, recurring revenues. ELECTRICAL CONTRACTORS. Sales to electrical contractors accounted for approximately 39% of our sales in 1998, while representing approximately 41% of the electrical distribution market in 1997. These customers range from large contractors for major industrial and commercial projects, the customer types we principally serve, to small residential contractors which represent a small portion of our sales. Electrical products purchased by contractors typically account for approximately 40% to 41

44 50% of the total installed project cost, and, therefore, accurate cost estimates and competitive material costs are critical to a contractor's success in obtaining profitable projects. Contractors choose a distributor on the basis of price, various support services such as design assistance, bill of material development, project management capabilities, credit policies and inventory availability. UTILITIES. Sales to utilities accounted for approximately 15% of our sales in 1998, while representing approximately 8% of the electrical distribution market in 1997. This market includes large investor-owned utilities, rural electric cooperatives and municipal power authorities. We provide our utility customers with an extensive range of supplies to meet their MRO and capital projects needs. Integrated supply arrangements are also important in this market as cost pressures and deregulation cause utility customers to streamline procurement practices. Recent trends in the utility industry favor utility-oriented electrical distributors like us. The most important trend is the deregulation of utility power generation, which has forced large utilities to seek better asset utilization and cost savings in all aspects of their operations, including purchasing and supply management. In focusing on their core business, some have outsourced supply functions in order to reduce costs and enhance cash flow. COMMERCIAL, INSTITUTIONAL AND GOVERNMENTAL CUSTOMERS. Sales to commercial, institutional and governmental customers accounted for approximately 5% of our sales in 1998, while representing approximately 13% of the electrical distribution market in 1997. This fragmented market includes schools, hospitals, property management firms, retailers and government agencies of all types. Through a recent acquisition, we now have a platform to sell integrated lighting control and distribution equipment in a single package for multi-site specialty retailers, restaurant chains and department stores. DISTRIBUTION NETWORK BRANCH NETWORK. We have over 330 branches, of which approximately 275 are located in the U.S., approximately 50 are located in Canada and the remainder are located in Puerto Rico, Mexico, Guam, Singapore and the United Kingdom. Over the last three years we have opened approximately 15 branches per year, principally to service National Accounts customers. In addition to consolidations in connection with acquisitions, we occasionally close or consolidate existing branch locations to improve operating efficiency. DISTRIBUTION CENTERS. To support our branch network, we have five distribution centers located near Pittsburgh, Pennsylvania, serving the Northeast and Midwest U.S.; near Reno, Nevada, serving the Western U.S.; near Memphis, Tennessee, serving the Southeast and Central U.S.; near Montreal, Quebec, serving Eastern and Central Canada; and near Vancouver, British Columbia, serving Western Canada. Our distribution centers add value for our branches and customers through the combination of a broad and deep selection of inventory, on-line ordering, same day shipment and central order handling and fulfillment. Our distribution center network reduces the lead-time and improves the reliability of our supply chain, giving us a distinct competitive advantage in customer service. Additionally, the distribution centers reduce the time and cost of supply chain activities through automated replenishment and warehouse management systems, and economies of scale in purchasing, inventory management, administration and transportation. SALES ORGANIZATION GENERAL SALES FORCE. Our general sales force is based at the local branches and comprises approximately 2,200 of our employees, almost half of whom are outside sales representatives and the remainder are inside sales personnel. Outside sales representatives, who have an average of more than 42

45 eight years of experience with us, are paid under a compensation structure which is heavily weighted towards commissions. They are responsible for making direct customer calls, performing on-site technical support, generating new customer relations and developing existing territories. The inside sales force is a key point of contact for responding to routine customer inquiries such as price and availability requests and for entering and tracking orders. NATIONAL ACCOUNTS. We believe that we have the largest National Accounts sales force in the electrical distribution industry, led by an experienced group of sales executives who negotiate and administer contracts, coordinate branch participation and identify sales and service opportunities. National Accounts managers' efforts are aligned by targeted customer industries, including automotive, pulp and paper, petrochemical, steel, mining and food processing. DATA COMMUNICATIONS. Sales of data communications products are supported by a dedicated group of outside and inside sales representatives who focus primarily on the premise wiring systems market. This team is supported by additional resources in the purchasing, inventory management, product training, product management and regional sales areas. We also operate a training facility where customers and the general sales force can receive industry-recognized certification in data communications product installation. MAJOR PROJECTS. Since 1995 a group of highly experienced sales managers target, on a national basis, the market for large construction projects with electrical material valued in excess of $1 million. Our approach distinguishes us from almost all of our competitors, which typically handle even the largest construction projects on a local basis. Through the Major Projects Group, we can meet the needs of contractors for complex construction projects such as new sports stadiums, industrial sites, water treatment plants, airport expansions, healthcare facilities and correctional institutions. e-COMMERCE. We have recently entered into a strategic alliance with Datastream Systems, Inc. to unite their customer base, the largest in the maintenance software market, with our nationwide distribution network. The initiative is part of Datastream's overall electronic commerce effort, called e-MRO(SM), which enables customers to search, select and purchase from a broad selection of MRO supplies through the Internet. INTERNATIONAL OPERATIONS To serve the Canadian market, we operate a network of approximately 50 branches in nine provinces. Branch operations are supported by two distribution centers located near Montreal and Vancouver. With sales of approximately US$272 million, Canada represented 9% of our total sales in 1998. The Canadian market for electrical distribution is considerably smaller than the U.S. market, with roughly US$2.4 billion in total sales in 1997, according to industry sources. We are continuing to build our international presence outside of the U.S. and Canada, principally by following our National Accounts customers and key suppliers into their high growth markets, thereby limiting start-up risk and enhancing profit. We sell internationally through domestic export sales offices located within North America and sales offices in international locations. We have recently opened offices in Aberdeen, Scotland and London, England to support our sales efforts in Europe, Africa and the former Soviet Union, and an office in Singapore to support our sales in Asia. We also recently opened two branches in the Mexico City area. MANAGEMENT INFORMATION SYSTEMS Our corporate information system, WESCOM, provides low cost, highly functional processing of a full range of our business operations, such as customer service, inventory and logistics management, accounting and administrative support. The system has been upgraded with decision support, 43

46 executive information system analysis and retrieval capabilities to provide detailed income statement and balance sheet variance and trend reporting at the branch level. The system also provides activity-based costing capabilities for analyzing profitability by customer, sales representative and shipment type. Sales and margin trends and variances can be analyzed by branch, customer, product category, supplier or account representative. The WESCOM system is fully distributed within WESCO, and every branch (other than EESCO and certain newly acquired branches) utilizes its own computer system to support local business activities. Telecommunication links through a central system give each branch access to information on inventory status in our distribution centers as well as other branches and an increasing number of on-line suppliers. We are developing an upgraded version of the WESCOM system to be released in 1999. This new version, WESNET, will link all branch operations through an intranet technology. EESCO operates its own system which is linked to our central system. We intend to integrate EESCO into the WESNET system over the next 12 months which is expected to reduce costs associated with operating dual systems. We routinely process customer orders, shipping notices, suppliers purchase orders, and funds transfer via EDI transactions with our trading partners. Our electronic commerce strategy calls for tighter linkages to both customers and suppliers through greater use of technological advances, including Internet and CD-ROM catalogs, bar-coding, enhanced EDI and other innovative improvements. Our integrated supply services are supported by our proprietary procurement and inventory management systems. These systems provide a fully integrated, flexible supply chain platform that currently handles over 95% of our integrated supply customers' transactions electronically. Our configuration options for a customer range from on-line linkages to the customer's business and purchasing systems, to total replacement of a customer's procurement and inventory management system for MRO supplies. COMPETITION We compete directly with national, regional and local providers of electrical and other industrial MRO supplies. Competition is primarily focused on the local service area and is generally based on product line breadth, product availability, service capabilities and price. We believe that we have certain competitive advantages over many of our local competitors, which are not able to carry the range of products stocked by us, offer our depth of value-added services or achieve our level of purchasing economies of scale. Another source of competition is buying groups formed by smaller distributors to increase purchasing power and provide some cooperative marketing capability. While increased buying power may improve the competitive position of buying groups locally, we believe these groups have not been able to compete effectively with us for National Accounts customers due to the difficulty in coordinating a diverse ownership group. EMPLOYEES As of December 31, 1998, we had approximately 5,450 employees worldwide, of which approximately 4,700 were located in the U.S. and approximately 750 in Canada and our other foreign locations. Less than 5% of our employees are represented by unions. We believe our labor relations are generally good. PROPERTIES We have over 330 branches, of which approximately 275 are located in the U.S., approximately 50 are located in Canada and the remainder are located in Puerto Rico, Mexico, Guam, Singapore 44

47 and the United Kingdom. Approximately 30% of branches are owned facilities, and the remainder are leased.

Each class will consist, as nearly as possible, of one-third of the whole number of the Board of Directors. Directors for each class will be elected at the annual meeting of stockholders held in the year in which the term for such class expires. Upon election, directors will serve thereafter for three years, and will hold office until their successors are elected and qualified. There are currently seven members of the Board of Directors. The term of Class I directors will expire in 2000, the term of Class II directors in 2001 and the term of Class III directors in 2002. Our Board of Directors has three standing committees: an Executive Committee, an Audit Committee and a Compensation Committee. The Executive Committee consists of Messrs. Singleton, Cheshire, Haley and Stern, with Mr. Singleton serving as Chairman. It is responsible for overseeing the management of the affairs and business of WESCO and has been delegated authority to exercise the powers of the Board during intervals between Board meetings. The Audit Committee consists of Messrs. Singleton, Tarr and Tutrone, with Mr. Singleton serving as Chairman. After the offering, the Audit Committee will consist of Mr. Tarr as Chairman and another independent director to be appointed. It is responsible for recommending the firm to be appointed as independent accountants to audit WESCO's financial statements and to perform services related to the audit; reviewing the scope and results of the audit with the independent accountants; reviewing with the management and the independent accountants WESCO's year end operating results; considering the adequacy of the internal accounting and control procedures of WESCO, reviewing the non-audit services to be performed by the independent accountants, if any, and considering the effect of such performance on the accountants' independence. The Compensation Committee consists of Messrs. Stern, Singleton, Tutrone and Way, with Mr. Stern serving as Chairman. It is responsible for the review, recommendation and approval of compensation arrangements for directors and executive officers, for the approval of such arrangements for other senior level employees, and for the administration of certain benefit and compensation plans and arrangements of WESCO. OUTSIDE DIRECTOR COMPENSATION Each director of WESCO who is not an employee of WESCO or any of its subsidiaries or Cypress is entitled to receive an annual director's fee of $25,000. Effective January 1, 1999, WESCO established the 1999 deferred compensation plan for non-employee directors under which non-employee directors can elect to defer 25% or more of the annual director's fee. Amounts deferred under this arrangement will, on the deferral date, be converted into stock units (common stock equivalents) which will be credited to a bookkeeping account in the director's name. For purposes of determining the number of stock units to be credited to a director for a particular year, the average of the high and low trading prices of the common stock on the first trading day in January of that year will be used. Distribution of deferred stock units will be made in a lump sum or installments, in the 48

51 form of shares of common stock, in accordance with the distribution schedule selected by the director at the time the deferral election is made. EXECUTIVE COMPENSATION The information set forth below describes the components of the total compensation of our Chief Executive Officer and our four other most highly compensated executive officers, based on 1998 salary and bonuses.

52 EMPLOYMENT AGREEMENTS In connection with the recapitalization, we entered into an employment agreement with Mr. Haley providing for a rolling employment term of three years. Pursuant to his agreement, Mr. Haley is entitled to an annual base salary of $500,000 and an annual incentive bonus equal to a percentage of his annual base salary ranging from 0% to 200%. The actual amount of Mr. Haley's annual incentive bonus will be determined based upon our financial performance as compared to the annual performance objectives established for the relevant fiscal year. If Mr. Haley's employment with us is terminated by us without "cause", by Mr. Haley for "good reason" or as a result of Mr. Haley's death or disability (any such termination, a "Qualifying Termination"), Mr. Haley (or, in the event of his death, Mr. Haley's spouse) is entitled to continued payments of his average annual base salary and his average annual incentive bonus (reduced by any disability payments, if applicable) for the three-year period, or in the case of a termination due to Mr. Haley's death or disability, the two-year period, following such termination, and continued welfare benefit coverage for the two-year period following such termination. In addition, in the event of any such Qualifying Termination, all outstanding options held by Mr. Haley will become fully vested. The agreement further provides that, in the event of the termination of Mr. Haley's employment by us without cause or by Mr. Haley for good reason, in either such case, within the two-year period following a "change in control" of WESCO (as defined in such agreement) (such termination, a "Qualifying CIC Termination"), in addition to the termination benefits described above, Mr. Haley is entitled to receive continued welfare benefit coverage and payments in lieu of additional contributions to our Retirement Savings Plan and Deferred Compensation Plan for the three year period following such Qualifying CIC Termination. We have agreed to provide Mr. Haley with an excise tax gross up with respect to any excise taxes Mr. Haley may be obligated to pay pursuant to Section 4999 of the United States Internal Revenue Code of 1986 on any excess parachute payments. In addition, following a change in control, Mr. Haley is entitled to a minimum annual bonus equal to 50% of his base salary and the definition of "good reason" is modified to include certain additional events. The agreement also contains customary covenants regarding nondisclosure of confidential information and non-competition and non-solicitation restrictions. In connection with our acquisition of EESCO, we entered into an employment agreement with Mr. Weiss, pursuant to which we agreed to employ Mr. Weiss during the period commencing on the date of the acquisition and ending on December 31, 1998. During the employment term under the agreement, Mr. Weiss was entitled to an annual base salary of $300,000 and an annual performance-based incentive bonus equal to a percentage of his annual base salary, not to exceed 75%. The agreement also contained customary covenants regarding nondisclosure of confidential information and non-competition and non-solicitation restrictions. Mr. Weiss retired from WESCO effective December 31, 1998. 1998 STOCK OPTION PLAN In connection with the recapitalization, we established a 1998 stock option plan to provide certain of WESCO's executive and key employees options to purchase shares of common stock. The 1998 stock option plan is administered by the Compensation Committee, which is constituted in such a way that, to the extent practicable, awards under the 1998 stock option plan qualify, or will qualify when granted, for exemption under Rule 16b-3 of the Securities Exchange Act of 1934 and as performance-based compensation under Section 162(m) of the Internal Revenue Code of 1986. The Compensation Committee has the authority to select employees to whom awards are granted and to set the terms, conditions and provisions of such awards. In addition, the Compensation Committee is authorized, by majority action, to prescribe, amend and rescind rules and regulations relating to the administration of the 1998 stock option plan, to make determinations with respect to the vesting and exercisability of the 1998 plan options, and to make all other determinations necessary or advisable 50

53 for the administration and interpretation of the 1998 stock option plan. The 1998 stock option plan provides that the Board may adjust the number and class of shares available for issuance under the 1998 stock option plan and the number and class of shares subject to and exercise price of any outstanding 1998 plan options as necessary or appropriate to reflect any common stock dividend, stock split or share combination or any recapitalization, merger, consolidation, exchange of shares, liquidation or dissolution of WESCO. A total of shares of common stock were authorized for issuance under the 1998 stock option plan. The exercise price per share of common stock to be purchased upon exercise of the 1998 plan options is determined by the Compensation Committee's evaluation of the fair market value per share of the common stock on the date of the grant of the option. At the discretion of the Compensation Committee, the exercise price of any 1998 plan options exercised after the offering may be paid in full or in part in the form of shares of common stock already owned and held for at least six months by the participant, based on the fair market value of such common stock on the date of exercise, as determined by the Board. As of , 1999, options to purchase shares of common stock had been granted under the 1998 stock option plan, of which (1) none had been canceled or exercised, (2) with a weighted exercise price of $ per share remained outstanding, and (3) none were exercisable. We expect to file a registration statement on Form S-8 with respect to the 1998 stock option plan after the offering. After giving effect to the foregoing, 1998 plan options remained available for grant under the 1998 stock option plan. Change in Control Provisions In the event of a "change in control" (as defined in the 1998 stock option plan), outstanding 1998 plan options, whether or not exercisable, will be canceled in exchange for a cash payment with respect to each share of common stock subject to such 1998 plan options equal to the excess of (1) the value per share of the common stock in the transaction giving rise to the change in control over (2) the per share exercise price, unless the Compensation Committee determines in good faith, prior to the change in control, that the outstanding 1998 plan options will be honored or assumed by the successor in a manner that provides the 1998 stock option plan participants with rights at least as favorable as those prevailing immediately prior to the change in control. The offering has not resulted in a "change in control." Management Stock Option Agreements Each participant under the 1998 stock option plan is required to enter into a management stock option agreement specifying the exercise price and duration of the 1998 plan options being granted and such other terms consistent with the 1998 stock option plan as the Compensation Committee determines. Certain other terms of the management stock option agreements are summarized below. Transferability of Options; Repurchase of Options The 1998 stock option plan provides that no award granted under the 1998 stock option plan may be disposed of in any way, other than by will or by the laws of descent and distribution. All 1998 plan options granted pursuant to the 1998 stock option plan are exercisable only by the participant to whom such 1998 plan options were granted during his or her lifetime. Following the death of a participant, all rights with respect to 1998 plan options that were exercisable by the participant at the time of his or her death may be exercised by the participant's beneficiary or estate provided that the deceased participant's beneficiary agrees in writing to be bound by the provisions of the 1998 stock option plan and the management stock option agreement. The management stock option agreements 51

54 also contain certain repurchase rights and obligations of WESCO, which will terminate upon consummation of the offering. Exercise of Options Outstanding 1998 plan options granted under the 1998 stock option plan consist of two parts: a portion which is subject to time-based vesting and a portion which is subject to performance-based vesting. The time-based 1998 plan options will vest at a rate of 25% on each June 5 beginning in 1999 and ending in 2002. Performance-based 1998 plan options will become fully vested and exercisable on the earlier of January 1, 2008 or the grantee's sixty-fifth birthday, but may vest earlier (25% per year from 1998 through 2001), if WESCO meets certain annual performance goals. Termination of Options All 1998 plan options terminate on the tenth anniversary of the date of grant, unless terminated earlier as described below. Upon termination of a participant's employment with WESCO, unless otherwise determined by the Compensation Committee, (1) any unexercisable 1998 plan options will terminate and will not be exercisable, and (2) then exercisable 1998 plan options will terminate within certain specified periods depending upon the circumstances of the termination of employment. Federal Income Tax Aspects of the 1998 Stock Option Plan The 1998 plan options are non-qualified stock options, i.e., they do not qualify as "incentive stock options" under Section 422 of the U.S. Internal Revenue Code. The grant of a 1998 plan option has no tax consequences to WESCO or to the participant. Upon exercise of a 1998 plan option, however, the participant will recognize taxable ordinary income equal to the excess of the fair market value on the date of the exercise of the shares of the common stock acquired over the exercise price of the 1998 plan option, and that amount will be deductible for federal income tax purposes by WESCO. The holder of the option shares will, upon a later disposition of such shares, recognize short term or long term capital gain or loss, depending on the holding period of the shares but WESCO will not be entitled to an additional tax deduction. 1994 STOCK OPTION PLAN Under our 1994 stock option plan, the Compensation Committee, which is responsible for administering the 1994 stock option plan, may grant to certain executives, officers, and other key employees options to purchase up to an aggregate of [181,000] shares of common stock (as adjusted for the to one stock dividend declared and paid prior to the offering). In connection with the recapitalization, future issuances of options under the 1994 stock option plan were terminated and all options granted under the 1994 stock option plan became fully vested. The outstanding 1994 plan options were granted with an exercise price per share equal to the fair market value (as defined in the related stock option agreements described below) per share on the date of grant as determined by the Compensation Committee. As of , 1999, 1994 plan options to purchase shares of common stock with a weighted average exercise price of $ were exercisable. Change in Control Provisions In the event of a change in control (as defined in the 1994 stock option plan), outstanding 1994 plan options will be canceled in exchange for a cash payment with respect to each share of common stock subject to such 1994 plan options equal to the excess of (1) the value per share of the common stock in the transaction giving rise to the change in control over (2) the per share exercise price, unless the Compensation Committee determines in good faith, prior to the change in control, that the 52

55 outstanding 1994 plan options will be honored or assumed by the successor in a manner that provides the option participants with rights at least as favorable as those prevailing immediately prior to the change in control. The offering will not result in a change in control. Termination of Options All 1994 plan options terminate on the tenth anniversary of the date of grant, unless terminated earlier as described below. Upon termination of a participant's employment with WESCO, unless otherwise determined by the Compensation Committee, in the case of termination other than for cause (as defined in the 1994 stock option plan), then exercisable 1994 plan options will terminate within certain specified periods depending upon the circumstances of the termination of employment. Transferability of Options; Repurchase of Options The 1994 plan options will not be transferable or assignable other than by will or by the laws of descent, and a 1994 plan option can be exercised only by the participant to whom it is granted or by the participant's estate or designated beneficiary upon such participant's death. Unless the Compensation Committee otherwise determines, each 1994 plan option agreement provides that the participant, in respect of shares purchased upon the exercise of any 1994 plan option, is entitled to the benefits of, and bound by the obligations in, the registration and participation agreement, including certain demand and "piggyback" registration rights thereunder. The 1994 stock option plan also contains certain repurchase rights and obligations of WESCO, which will terminate upon the consummation of the offering. Federal Income Tax Aspects of the 1994 Stock Option Plan The grant and exercise of 1994 plan options will have the same tax consequences as the grant and exercise of 1998 plan options. See "1998 Stock Option Plan -- Federal Income Tax Aspects." STOCK OPTION PLAN FOR BRANCH EMPLOYEES A total of shares of common stock may be issued under our stock option plan for branch employees. The Compensation Committee, which is responsible for administering the branch option plan, may grant to our branch managers and other key employees employed at a branch or contributing significantly to growth and profitability of a branch options to purchase shares of common stock. Branch options that are canceled, terminated or forfeited without exercise will again be available for grant. The Board may at any time amend or terminate the branch option plan, but may not adversely affect the rights of any participant with respect to branch options granted prior to such action, unless the participant consents. As of , 1999, options had been granted, of which (1) branch options had been canceled without exercise, (2) none had been exercised, (3) branch options granted with a weighted average exercise price of $ per share were outstanding, and (4) branch options with an exercise price of $ were exercisable. After giving effect to the foregoing, branch options remained available for grant under the branch option plan. The outstanding branch options were granted with an exercise price per share determined by the Board to represent the estimated fair market value (as defined in the related stock option agreements described below) per share on the date of grant. At the discretion of the Compensation Committee, the exercise price of any branch option exercised after the offering may be paid in full or in part in the form of shares of common stock already owned and held for at least six months by the participant, based on the fair market value of such common stock on the date of exercise, as determined by the Board. None of the named executives currently participate in the branch option plan. 53

56 Branch options are granted to participants as soon as practicable following the end of each performance period under the branch option plan. The first such performance period commenced on February 28, 1994 and ended on December 31, 1996, and the second such performance period commenced on January 1, 1997 and is scheduled to end on December 31, 1999. Branch options are allocated to branch or division employees by the Compensation Committee based primarily on the achievement of branch or division performance objectives during each performance period. Under the terms of the recapitalization agreement, the Compensation Committee adopted a resolution causing 100% of all branch options to be rolled over and remain outstanding without any acceleration of the vesting schedule. We expect to file a registration statement on Form S-8 with respect to the branch option plan after the offering. Change in Control Provisions In the event of a change in control (as defined in the branch option plan), outstanding branch options, whether or not exercisable, will be canceled in exchange for a cash payment with respect to each share of common stock subject to such branch options equal to the excess of (1) the value per share of the common stock in the transaction giving rise to the change in control over (2) the per share exercise price, unless the Compensation Committee determines in good faith, prior to the change in control, that the outstanding branch options will be honored or assumed by the successor in a manner that provides the participants with rights at least as favorable as those prevailing immediately prior to the change in control. The offering will not result in a change in control. Branch Option Agreements Each participant is required to enter into a branch option agreement specifying the exercise price and duration of the branch options being granted and such other terms consistent with the branch option plan as the Compensation Committee determines. Certain other terms of the branch option agreement are summarized below. Exercise of Branch Options; Exercise Price Except as otherwise determined by the Compensation Committee or in connection with a change in control, branch options become exercisable in one-third installments on each of the first, third, and fifth anniversaries of the date of grant. Upon exercise of a branch option, the participant is required to enter into a stock subscription agreement. The per share exercise price of any branch option may not be less than the greatest of (1) the fair market value (as defined in the branch option plan) per share of common stock as of the end of the related performance period, (2) such fair market value as of the date of grant, and (3) $100. Termination of Branch Options All branch options terminate on the tenth anniversary of the date of grant, unless terminated earlier as described below. Upon termination of a participant's employment with WESCO, unless otherwise determined by the Compensation Committee, (1) any unexercisable branch options held by such participant will terminate and will not be exercisable, (2) in the case of termination other than for cause (as defined in the branch option plan), then exercisable branch options will terminate within certain specified periods depending upon the circumstances of the termination of employment, and (3) in the case of termination for cause, all branch options held by such participant, whether or not then exercisable, will terminate immediately. 54

57 Transferability of Branch Options; Repurchase of Branch Options The branch options will not be transferable or assignable other than by will or by the laws of descent, and a branch option can be exercised only by the participant to whom it is granted or by the participant's estate or designated beneficiary upon such participant's death. Unless the Compensation Committee otherwise determines, each branch option agreement provides that the branch plan participant, in respect of shares purchased upon the exercise of any branch option, is entitled to the benefits of, and bound by the obligations in, the registration and participation agreement, including certain demand and "piggyback" registration rights thereunder. The branch option agreements also contain certain repurchase rights and obligations of WESCO, which will terminate upon the consummation of the offering. Federal Income Tax Aspects of the Branch Options The grant and exercise of branch options will have the same federal income tax consequences as the grant and exercise of the 1998 options. See "1998 Stock Option Plan -- Federal Income Tax Aspects." LONG-TERM INCENTIVE PLAN In , 1999 we established the 1999 Long-Term Incentive Plan (the "LTIP") to assist us in attracting and retaining key employees and to act as an incentive for such employees to achieve corporate objectives. The LTIP provides for awards of up to 120,000 shares (without adjusting for the stock split effected in the form of the stock dividend to be declared and paid prior to the Offering) of Common Stock that may be granted in the form of stock options, accelerated ownership options, restricted stock awards and performance awards. The LTIP is administered by the Compensation Committee of the Board of Directors. Employees of the Company or any subsidiary who meet eligibility requirements as determined by the Compensation Committee will be eligible to participate in the LTIP. The terms and conditions of all awards made pursuant to the LTIP are determined by the Compensation Committee. Under this program, designated employees will receive awards based on the attainment of performance goals or other such criteria as the Compensation Committee may determine. The performance targets, if designated, may include specified levels of sales performance, EBITDA, operating margin, earnings per share, return on investment and/or return on stockholders' equity. No participant can receive awards under the LTIP in any calendar year for more than shares of Common Stock. In the event of a change in control (as defined in the LTIP), stock options immediately become exercisable, the restrictions on all restricted shares lapse and all performance awards immediately become payable. The shares to be offered under the LTIP will be either authorized and unissued shares or issued shares which have been reacquired by the Company. The Compensation Committee initially intends to establish two option grant programs under the LTIP: a "Management Incentive Program" for key management and an "Employee Performance Program." Under these programs, designated employees will receive option grants subject to attainment of performance goals and such other criteria as the Compensation Committee may determine. 55

(2) Amounts represent hypothetical gains that could be achieved for the respective options if exercised at the end of the option term. These gains are based on assumed rates of stock price appreciation of 5% and 10% compounded annually from the date the respective options were granted to their expiration date. These assumptions are not intended to forecast future appreciation of our stock price. The potential realizable value computation does not take into account federal or state income tax consequences of option exercises or sales of appreciated stock. AGGREGATED OPTION EXERCISES IN LAST FISCAL YEAR AND FISCAL YEAR-END OPTION VALUES The following table sets forth information for each named executive with regard to the aggregate stock options held at December 31, 1998. No stock options were exercised by any of the named executives during 1998.

The foregoing options were issued under our existing stock option plan. In connection with the recapitalization, the Board caused all unvested options (including those held by the named executives) under this plan to vest (and become exercisable) upon the closing of the recapitalization. 56

59 RETENTION BONUS PAYMENT We paid an aggregate amount of approximately $11 million to a group of approximately 45 managers (including the named executives) upon the closing of the recapitalization. With respect to each of these managers, payment was equal to approximately one to two times base salary. Immediately prior to the closing of the recapitalization, Clayton, Dubilier & Rice ("CD&R"), which was the majority shareholder of WESCO prior to the recapitalization, made an equity contribution to WESCO equal to approximately one-half of this aggregate amount. COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION During 1998 prior to the recapitalization, a former outside director and three former directors affiliated with CD&R served on the Compensation Committee. We had agreed to indemnify certain former members of the Board affiliated with CD&R and such CD&R affiliates against liabilities incurred under securities laws or with respect to their previous services for us. At December 31, 1998, three directors affiliated with Cypress served on the Compensation Committee. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS AMENDED AND RESTATED REGISTRATION AND PARTICIPATION AGREEMENT In connection with the recapitalization, an investor group led by Cypress which included, among others, Chase Capital Partners and Co-Investment Partners, L.P., CD&R, Westinghouse and WESCO entered into a registration and participation agreement, which amended and restated the previous agreement among CD&R, Westinghouse and WESCO, to reflect, among other things, the succession of the investor group to CD&R's and Westinghouse's rights and obligations thereunder. Pursuant to the registration and participation agreement, the investor group and the management stockholders (described below) have the right, under certain circumstances and subject to certain conditions, to request that we register under the Securities Act shares of common stock held by them. Subject to certain conditions and exceptions, the investor group and the management stockholders also have the right to require that shares of common stock held by them be included in any registration under the Securities Act commenced by us. Neither the investor group nor any of the management stockholders have requested that shares of common stock held by them be included in this offering. The registration and participation agreement provides that we will pay all expenses in connection with the first three registrations requested by the investor group and the management stockholders. The registration and participation agreement also provides that we will indemnify the investors and the management stockholders and their affiliates for certain liabilities they may incur under the securities laws. The registration and participation agreement also contains certain restrictions which prohibit the sale of common stock by Cypress unless Cypress provides each holder of common stock entitled to the benefits of the registration and participation agreement (including the other members of the investor group and the management stockholders) with a 30-day prior notice pursuant to which such holders may agree to participate in such sale on a pro rata basis with Cypress. The registration and participation agreement provides that, if Cypress sells all of its shares of common stock to a third party, Cypress may require such other holders of common stock to sell all of their shares to such third party pursuant to such sale at the same price and on the same terms as Cypress. In addition, the registration and participation agreement provides that if prior to any public equity offering by us, we issue additional shares of common stock to Cypress (subject to certain exceptions), we will offer to all holders of registrable securities that are "accredited investors" the right to purchase a pro rata 57

60 share of the newly-issued shares (based on each holder's equity interest in us) at the same price and on the same terms as Cypress. In addition, the registration and participation agreement provides that so long as Cypress owns any of our securities, Cypress shall have the right to designate one director to our board of directors and the board of directors of WESCO Canada. At the time we entered the registration and participation agreement, Cypress was not affiliated with WESCO, and we believe the transaction was made on terms no less favorable to us than we could have obtained from an unaffiliated third party. MANAGEMENT STOCKHOLDERS Each member of management who holds common stock is a party to a stock subscription agreement with us which provides that each management stockholder is entitled to certain benefits of, and bound by certain obligations in, the registration and participation agreement, including certain registration rights thereunder. These stock subscription agreements also provide the management stockholder with the right under certain limited circumstances to require us to purchase all of the management stockholder's shares of common stock at the then fair market value based upon certain events. Pursuant to the stock option agreements governing each management stockholder's stock options, such management stockholder also has the right under certain limited circumstances to require us to purchase all of such management stockholder's options at the then fair market value of the common stock minus the exercise price upon such events. At December 31, 1998, the redemption value of the shares and exercisable portion of the options was $130.3 million. See Note 11 to Consolidated Financial Statements. These repurchase rights will terminate upon the consummation of this offering. In addition, such stock subscription agreements and stock option agreements provide that such rights are subject to, and limited by, any restrictions contained in the credit facilities, the indentures or other debt instruments on our ability to redeem or repurchase equity held by management stockholders. A portion of the purchase price paid for the common stock purchased by certain management stockholders has been financed by full-recourse bank loans guaranteed by us. As of December 31, 1998, Messrs. Burleson, Goodwin, Haley, Kramp, Mehta, Piraino, Swed, Thimjon, Van and Vanderhoff had outstanding loans guaranteed by us in the amount of $0, $260,572, $3,054,872, $68,700, $1,487,903, $266,634, $343,200, $0, $49,686 and $282,832, respectively and since January 1, 1997, the largest amounts outstanding under such loans were $68,800, $260,572, $3,054,872, $68,800, $1,487,903, $266,634, $587,959, $167,262, $49,686 and $282,832, respectively. PAYMENTS IN CONNECTION WITH THE RECAPITALIZATION In connection with the recapitalization, Cypress received a transaction fee of approximately $9.5 million from us and was reimbursed for all out-of-pocket expenses. We have also agreed to indemnify Cypress to the fullest extent allowable under applicable Delaware law and against any suits, claims, damages or expenses which may be made against or incurred by Cypress under applicable securities laws, including in connection with the offering. Approximately $517.5 and $62.1 million of the equity consideration paid in connection with the recapitalization was paid to CD&R and Westinghouse, respectively, to purchase their shares of common stock. In addition, approximately $52.1 million of the equity consideration was paid to purchase 100,000 shares held by Westinghouse upon exercise of an option granted at the date of formation with an exercise price of $100 per share. Westinghouse also held approximately $66.6 million of our formerly existing indebtedness which was repaid in connection with the recapitalization. See "Management's Discussion and Analysis of Financial Conditions and Results of Operations -- Recent Developments" and Notes 3 and 16 to Consolidated Financial Statements. 58

61 The recapitalization was a negotiated transaction between WESCO, CD&R and Cypress, and we believe the transaction was made on terms no less favorable to us than could have been obtained from an unaffiliated third party. OTHER TRANSACTIONS Prior to the recapitalization, Westinghouse and CD&R were considered to be related parties. In 1998, we purchased $2.8 million from, and sold $7.3 million worth of products to, Westinghouse. See Note 16 to Consolidated Financial Statements. We paid an affiliate of CD&R fees of approximately $0.1 million for advisory, management consulting and monitoring services rendered during 1998. We believe these transactions were made on terms no less favorable to us than we could have obtained from an unaffiliated third party. 59

62 PRINCIPAL STOCKHOLDERS The following table sets forth certain information known to us with respect to the beneficial ownership of common stock as of , 1999 and as adjusted to reflect WESCO's sale of the common stock in the offering by (i) each person known by us to beneficially own more than five percent of our outstanding common stock, (ii) each of our directors, (iii) each executive officer named in the Summary Compensation Table, and (iv) all of our directors and officers as a group. Unless otherwise indicated, the person or persons named have sole voting and investment power. In determining the number and percentage of shares beneficially owned by each person, shares that may be acquired by such person pursuant to options or convertible stock exercisable or convertible within 60 days of the date hereof are deemed outstanding for purposes of determining the total number of outstanding shares for such person and are not deemed outstanding for such purpose for all other stockholders.

63 - ------------------------- * Represents holdings of less than 1%. (1) Cypress Merchant Banking Partners L.P. and Cypress Offshore Partners L.P. are affiliates of Cypress. The general partner of Cypress Merchant Banking Partners L.P. and Cypress Offshore Partners L.P. is Cypress Associates L.P. and The Cypress Group L.L.C. is the general partner of Cypress Associates L.P. Messrs. Singleton and Stern are members of Cypress and may be deemed to share beneficial ownership of the shares of common stock shown as beneficially owned by such Cypress funds. Such individuals disclaim beneficial ownership of such shares. (2) These shares constitute shares of non-voting Class B common stock which are convertible at any time into common stock at the option of the holder. (3) Mr. Weiss retired from WESCO effective December 31, 1998. 61

64 DESCRIPTION OF CAPITAL STOCK At the time of the offering, the authorized capital stock consists of 120,000,000 shares of common stock, par value of $.01 per share, 10,000,000 shares of Class B common stock, par value $.01 per share and 20,000,000 shares of preferred stock, par value $.01 per share. COMMON STOCK VOTING RIGHTS. Each holder of shares of common stock is entitled to one vote per share on all matters to be voted on by stockholders. Holders of common stock are not entitled to cumulative votes in the election of directors. DIVIDEND RIGHTS. The holders of common stock are entitled to dividends and other distributions if, as and when declared by the Board out of assets legally available therefor, subject to the rights of any holder of preferred stock, restrictions set forth in WESCO's credit facilities and restrictions, if any, imposed by other indebtedness outstanding from time to time. See "Dividend Policy" and "Management's Discussion and Analysis of Financial Conditions and Results of Operations -- Liquidity and Capital Resources." The holders of common stock and Class B common stock are entitled to equivalent per share dividends and distributions. OTHER RIGHTS. Upon the liquidation, dissolution or winding up of WESCO, the holders of shares of common stock would be entitled to share pro rata (on an equal basis with the holders of the Class B common stock) in the distribution of all of WESCO's assets remaining available for distribution after satisfaction of all its liabilities and the payment of the liquidation preference of any outstanding preferred stock. The holders of common stock have no preemptive or other subscription rights to purchase shares of WESCO, nor are they entitled to the benefits of any sinking fund provisions. No share of common stock issued in connection with or outstanding prior to the offering is subject to any further call or assessment. REDEEMABLE COMMON STOCK. Certain employees and key management of WESCO who hold common stock and options may require WESCO to repurchase in the event of death, disability or termination without cause during the term of employment, all of their shares and the exercisable portion of the options they hold. This repurchase right will terminate upon the consummation of the offering. CLASS B COMMON STOCK The Class B common stock (nonvoting) is identical to the common stock in all respects except that the holders of Class B common stock will have no right to vote, except as required by law. Shares of Class B common stock automatically convert into the same number of shares of common stock upon the sale or transfer by the holder thereof to a non-affiliate. To the extent permitted by law, each holder of Class B common stock is entitled to convert any or all shares of Class B common stock held into the same number of shares of common stock. PREFERRED STOCK The Board of Directors has the authority, without further action by the stockholders, to issue up to 20,000,000 shares of preferred stock in one or more series and to fix the number of shares, designations, voting powers, preferences, optional and other special rights and the restrictions or qualifications thereof. The rights, preferences, privileges and powers of each series of preferred stock may differ with respect to dividend rates, amounts payable on liquidation, voting rights, conversion rights, redemption provisions, sinking fund provisions and other matters. The issuance of shares of preferred stock could decrease the amount of earnings and assets available for distribution to holders of shares of common stock and Class B common stock and could adversely affect the rights and 62

65 powers, including voting rights, of holders of shares of common stock and Class B common stock. The existence of authorized and undesignated shares of preferred stock may also have an adverse effect on the market price of the common stock. In addition, the issuance of any shares of preferred stock could have the effect of delaying, deferring or preventing a change of control of WESCO. No shares of preferred stock are outstanding, and WESCO has no current intention to issue any shares of preferred stock. CERTAIN PROVISIONS OF THE AMENDED AND RESTATED CERTIFICATE OF INCORPORATION WESCO's Certificate of Incorporation, as amended and restated, provides for a classified Board of Directors in which directors are divided into three classes, each class being elected for a term of three years expiring at successive yearly intervals. In addition, the Certificate of Incorporation requires a vote of a majority of the remaining Board of Directors to fill a vacancy on the Board and does not permit vacancies to be filled by a vote of the stockholders. The Certificate of Incorporation provides that vacancies filled by the Board of Directors will be filled for the remainder of the term of the class in which the vacancy occurs. The Certificate of Incorporation further states that a decrease in the number of directors will not shorten the term of any incumbent. SECTION 203 OF THE DELAWARE GENERAL CORPORATION LAW We are a Delaware corporation subject to Section 203 of the DGCL. Section 203 provides in general that a stockholder acquiring more than 15% of the outstanding voting stock of a corporation subject to Section 203 (an "Interested Stockholder") but less than 85% of such stock may not engage in certain Business Combinations (as defined in Section 203) with the corporation for a period of three years subsequent to the date on which the stockholder became an Interested Stockholder unless (i) prior to such date the corporation's board of directors approve either the Business Combination or the transaction in which the stockholder became an Interested Stockholder or (ii) the Business Combination is approved by the corporation's board of directors and authorized by a vote of at least 66 2/3% of the outstanding voting stock of the corporation not owned by the Interested Stockholder. A "Business Combination" includes mergers, asset sales and other transactions resulting in financial benefit to a stockholder. Section 203 could prohibit or delay mergers or other takeover or change of control attempts with respect to WESCO and, accordingly, may discourage attempts that might result in a premium over the market price for the shares held by stockholders. TRANSFER AGENT AND REGISTRAR The Transfer Agent and Registrar for our common stock will be American Stock Transfer & Trust Company. 63

In addition, the credit agreement requires us to comply with specified financial ratios and tests. EVENTS OF DEFAULT. The credit agreement contains customary events of default. RECEIVABLES FACILITY The following is a summary of the material terms of the receivables facility entered into among WESCO Distribution, WESCO Canada, WESCO Receivables Corp., a special purpose wholly-owned subsidiary of WESCO Distribution, Chase as liquidity bank and funding agent for a multi-seller asset-backed commercial paper issuer. The following summary is qualified in its entirety by reference to the receivables sale agreements and the pooling agreement. 65

68 THE RECEIVABLES FACILITY. WESCO Receivables purchases the receivables generated by WESCO, WESCO Canada and certain other subsidiaries pursuant to two receivables sale agreements. The receivables sale agreements contain customary terms for similar transactions. WESCO Receivables has entered into a pooling agreement with Chase as trustee pursuant to which WESCO Receivables transfers all the receivables to a trust, and the commercial paper issuer, or in certain circumstances, the liquidity bank provides through the purchase of an undivided percentage ownership interest in the Trust. If the commercial paper issuer no longer wishes to, or is unable to, provide financing, which may occur at any time, the liquidity bank is committed to thereafter be the receivables purchaser. The receivables facility is supported by a commitment of the liquidity bank, subject to the terms and conditions of the pooling agreement, to purchase transferred interests for a period of approximately six years on a revolving basis in an amount not to exceed $300 million at any time. See Note 4 to Consolidated Financial Statements for further information concerning funding under the receivables facility. The trust, on behalf of the receivables purchasers, has a first priority perfected ownership or security interest in the receivables, the rights of WESCO Receivables under the receivables sale agreements and cash collections and other proceeds received in respect of the receivables. Pursuant to a servicing agreement entered into by the receivables sellers, WESCO Receivables and the trust, the receivables sellers have agreed to service the receivables for the trust; provided, that, upon the occurrence of certain events, the servicing agreement may be terminated by the trustee. COSTS. The effective financing rate under the receivables facility will be the weighted average of the interest rates on all outstanding commercial paper issued by the commercial paper issuer to fund its purchase of the transferred interests, except if the liquidity bank is the receivables purchaser, the effective financing rate will be either (i) adjusted LIBOR plus a margin of up to 2.25% per annum or (ii) ABR plus a margin of up to 1.25% per annum, at the option of WESCO Receivables, plus in each case the fees described below. FEES. WESCO Receivables has agreed to pay certain fees with respect to the receivables facility, including a commitment fee to the liquidity bank, a program fee and agent, arrangement and other similar fees. FACILITY REDUCTIONS. After the end of the revolving period, all collections in respect of receivables purchased by WESCO Receivables from the receivables sellers will be used to reduce the transferred interests of the receivables purchasers in the receivables. Additionally, at any time, WESCO Receivables at its option may reduce the purchase commitment upon notice to the receivables purchasers or terminate the purchases of transferred interests by the receivables purchasers. EARLY TERMINATION EVENTS. The pooling agreement contains certain early amortization events which will cause the termination of, or permit the Receivables Purchasers to terminate, the revolving period and effectively reduce the amount of financing available under the receivables facility to zero. REPLACEMENT FACILITY. Although WESCO Distribution received a six-year commitment, WESCO Distribution intends to replace the receivables facility through a securitization of the receivables in the capital markets or another securitization transaction. However, no assurance can be made that such transaction will be completed or, if completed, whether such transaction may have materially different terms from the receivables facility. 9 1/8% SENIOR SUBORDINATED NOTES DUE 2008 WESCO Distribution has outstanding $300 million in aggregate principal amount of its senior subordinated notes. The senior subordinated notes are subject to the terms and conditions of an indenture dated as of June 5, 1998 between WESCO Distribution and Bank One, N.A., as trustee. 66

69 The following summary of the material provisions of the senior subordinated notes does not purport to be complete, and is subject to, and qualified in its entirety by reference to, all of the provisions of the senior subordinated indenture and those terms made a part of the senior subordinated indenture and not otherwise defined herein are used below with the meanings set forth in the senior subordinated indenture. GENERAL. The senior subordinated notes will mature on June 1, 2008 and bear interest at 9 1/8% per annum, payable semi-annually on June 1 and December 1 of each year. The senior subordinated notes are general unsecured obligations of WESCO Distribution and are subordinated in right of payment to all existing and future senior debt of WESCO Distribution. The notes are unconditionally guaranteed, on an unsecured senior subordinated basis, jointly and severally, by WESCO. OPTIONAL REDEMPTION. The senior subordinated notes are subject to redemption at any time, at the option of WESCO Distribution, in whole or in part, on or after June 1, 2003 at redemption prices (plus accrued and unpaid interest) starting at 104.563% of principal (plus accrued and unpaid interest) during the 12-month period beginning June 1, 2003 and declining annually to 100% of principal (plus accrued and unpaid interest) on June 1, 2006 and thereafter. In addition, prior to June 1, 2001, WESCO Distribution may redeem up to 35% of the aggregate principal amount of the senior subordinated notes with the net proceeds of this offering or other equity offerings, to the extent such proceeds are contributed (within 120 days of any such offering) to WESCO Distribution as common equity, at a price equal to 109.125% of the principal (plus accrued and unpaid interest) provided that at least 65% of the original aggregate principal amount of the senior subordinated notes remains outstanding thereafter. CHANGE OF CONTROL. Upon the occurrence of a change of control (as defined in the senior subordinated indenture), each holder of the senior subordinated notes may require WESCO Distribution to repurchase all or a portion of such holder's senior subordinated notes at a purchase price equal to 101% of the principal amount thereof (plus accrued and unpaid interest). SUBORDINATION. The senior subordinated notes are general unsecured obligations of WESCO Distribution and are subordinate to all existing and future senior debt of WESCO Distribution. The senior subordinated notes will rank senior in right of payment to all subordinated Indebtedness of WESCO Distribution. CERTAIN COVENANTS. The senior subordinated indenture contains a number of covenants restricting the operation of WESCO Distribution, which, among other things, limit the ability of WESCO Distribution to incur additional indebtedness, pay dividends or make distributions, sell assets, issue subsidiary stock, restrict distributions from subsidiaries, create certain liens, enter into certain consolidations or mergers and enter into certain transactions with affiliates. EVENTS OF DEFAULT. Upon the occurrence of an event of default (as defined in the senior subordinated indenture), with certain exceptions, the trustee or the holders of at least 25% in principal amount of the then outstanding senior subordinated notes may accelerate the maturity of all the senior subordinated notes as provided in the senior subordinated indenture. 11 1/8% SENIOR DISCOUNT NOTES DUE 2008 WESCO has outstanding $87 million in aggregate principal amount of its senior discount notes. The senior discount notes are subject to the terms and conditions of an indenture dated as of June 5, 1998 between WESCO and Bank One, N.A., as trustee. The following summary of the material provisions of the senior discount notes does not purport to be complete, and is subject to, and qualified in its entirety by reference to, all of the provisions of the senior discount indenture and those terms made a part of the Senior Discount Indenture and not otherwise defined herein are used below with the meanings set forth in the senior discount indenture. 67

70 GENERAL. The senior discount notes will mature on June 1, 2008 and were sold at a discount resulting in a yield to maturity of 11.175% per annum, payable semi-annually on June 1 and December 1 of each year. The senior discount notes are generally unsecured obligations of WESCO and are subordinated in right of payment to all existing and future senior debt of WESCO. OPTIONAL REDEMPTION. The senior discount notes are subject to redemption at any time, at the option of WESCO, in whole or in part, on or after June 1, 2003 at redemption prices (plus accrued and unpaid interest) starting at 105.563% of principal (plus accrued and unpaid interest) during the 12-month period beginning June 1, 2003 and declining annually to 100% of principal (plus accrued and unpaid interest) on June 1, 2006 and thereafter. At any time prior to June 1, 2001, WESCO may redeem, in whole but not in part, the senior discount notes with the proceeds of an equity offering at a redemption price equal to 111.125% of the accreted value at the date of redemption. CHANGE OF CONTROL. Upon the occurrence of a change of control (as defined in senior discount indenture), each holder of the senior discount notes at a purchase price equal to 101% of the principal amount thereof (plus accrued and unpaid interest). SUBORDINATION. The senior discount notes are general unsecured obligations of WESCO and are subordinate to all existing and future senior debt of WESCO. The senior discount notes will rank senior in right of payment to all subordinated indebtedness of WESCO. CERTAIN COVENANTS. The senior discount indenture contains a number of covenants restricting the operations of WESCO, which, among other things, limit the ability of WESCO to incur additional indebtedness, pay dividends or make distributions, sell assets, issue subsidiary stock, restrict distributions from subsidiaries, create certain liens, enter into certain consolidations or mergers and enter into certain transactions with affiliates. EVENTS OF DEFAULT. Upon the occurrence of an event of default (as defined in the senior discount indenture), with certain exceptions, the trustee or the holders of at least 25% in principal amount of the then outstanding senior discount notes may accelerate the maturity of all the senior discount notes as provided in the senior discount indenture. CONVERTIBLE PROMISSORY NOTES WESCO issued four promissory notes to certain sellers in connection with four acquisitions, including Bruckner, which are convertible in whole or in part into common stock. Three outstanding notes in the aggregate principal amount of $32 million are automatically convertible into shares of common stock upon the offering. One note is convertible as to $5 million of its principal amount, at the election of the payee, into shares of common stock upon the offering. The number of shares of common stock into which each note is convertible is determined by dividing the unpaid principal amount, or the amount elected by the payee to be received in the form of shares of common stock, as the case may be, by the offering price. 68

71 SHARES ELIGIBLE FOR FUTURE SALE Upon the consummation of this offering, we will have shares of common stock issued and outstanding, including outstanding shares of Class B common stock which are convertible into common stock. All of the shares of common stock to be sold in the offering (and any shares sold upon exercise of the underwriters' over-allotment option) will be freely tradable without restrictions or further registration under the Securities Act, except for any shares purchased by an "affiliate" of WESCO (as that term is defined in Rule 144 under the Securities Act ("Rule 144")), which will be subject to the resale limitations of Rule 144. After the completion of the offering, we will have shares of common stock outstanding which are "restricted securities" as that term is defined in Rule 144 and are also subject to certain restrictions on disposition. Restricted securities may be sold in the public market only if registered or if they qualify for an exemption from registration under Rule 144 or Rule 701 under the Securities Act. Sales of restricted securities in the public market, or the availability of such shares for sale, could have an adverse effect on the price of the common stock. See "Risk Factors -- The Price of our Common Stock May Fluctuate Significantly" and "Risk Factors -- A Number of Shares Are or Will be Available for Future Sale." RULE 144 In general, under Rule 144, as currently in effect, a person (or persons whose shares are required to be aggregated) who has beneficially owned shares of common stock for at least one year, including a person who may be deemed an "affiliate" of WESCO, is entitled to sell, within any three-month period, a number of shares that does not exceed the greater of 1% of the total number of shares of the class of stock sold or the average weekly reported trading volume of the class of stock being sold during the four calendar weeks preceding such sale. A person who is not deemed an "affiliate" of WESCO at any time during the three months preceding a sale and who has beneficially owned shares for at least two years is entitled to sell such shares under Rule 144 without regard to the volume limitations as described above. As defined in Rule 144, an "affiliate" of an issuer is a person that directly or indirectly through the use of one or more intermediaries controls, is controlled by, or is under common control with, such issuer. The foregoing summary of Rule 144 is not intended to be a complete description thereof. , who, after the offering, will hold in the aggregate shares of common stock, for a period of 180 days after the date of this prospectus have agreed, pursuant to lock-up agreements, that they will not, without the prior written consent of Lehman Brothers Inc., offer, sell, contract to sell or otherwise dispose of any shares of common stock or securities exercisable or exchangeable for common stock or enter into any derivative transaction with similar effect as a sale of common stock. The restrictions described in this paragraph do not apply to (i) the sale of common stock to the underwriters in this offering, (ii) the issuance by WESCO of shares of common stock upon the exercise of an option or the conversion of a security outstanding on the date of this prospectus, (iii) transactions by any person other than WESCO relating to shares of common stock or (iv) the issuance by WESCO of shares of common stock pursuant to employee benefit plans, qualified stock option plans or other employee compensation existing on the date of this prospectus. REGISTRATION RIGHTS Pursuant to the registration and participation agreement, the investor group and the management stockholders have the right, under certain circumstances and subject to certain conditions, to request that we register under the Securities Act shares of our common stock held by them. Subject to certain conditions and exceptions, the investor group and the management stockholders also have the right to require that shares of common stock held by them be included in any registration under the Securities Act commenced by us. No such stockholder has requested to register its shares of common stock in the offering. The registration and participation agreement provides that we will pay all expenses in connection with the first three registrations requested by the investor group and the management stockholders. The registration and participation agreement also provides that we will indemnify the investors and the management stockholders and their affiliates for certain liabilities they may incur under the securities laws. 69

72 CERTAIN UNITED STATES FEDERAL TAX CONSIDERATIONS The following summary describes certain United States federal income and estate tax consequences that may be relevant to the purchase, ownership and disposition of common stock by a Non-U.S. Holder. For this purpose, a "Non-U.S. Holder" is any person who is, for United States federal income tax purposes, a foreign corporation, a non-resident alien individual, a foreign partnership or a foreign estate or trust. This discussion does not address all aspects of United States federal income and estate taxes and does not deal with foreign, state and local consequences that may be relevant to such Non-U.S. Holders in light of their personal circumstances. Furthermore, this discussion is based on provisions of the Internal Revenue Code of 1986, existing and proposed regulations promulgated thereunder and administrative and judicial interpretations thereof, as of the date hereof, all of which are subject to change. EACH PROSPECTIVE PURCHASER OF COMMON STOCK IS ADVISED TO CONSULT A TAX ADVISOR WITH RESPECT TO CURRENT AND POSSIBLE FUTURE TAX CONSEQUENCES OF ACQUIRING, HOLDING AND DISPOSING OF COMMON STOCK AS WELL AS ANY TAX CONSEQUENCES THAT MAY ARISE UNDER THE LAWS OF ANY U.S. STATE, MUNICIPALITY OR OTHER TAXING JURISDICTION. DIVIDENDS We do not anticipate paying cash dividends on our capital stock in the foreseeable future. See "Dividend Policy." In the event, however, that dividends are paid on shares of common stock, dividends paid to a Non-U.S. Holder of common stock generally will be subject to withholding of United States federal income tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty. However, dividends that are effectively connected with the conduct of a trade or business by the Non-U.S. Holder within the United States and, where a tax treaty applies, are attributable to a United States permanent establishment of the Non-U.S. Holder, are not subject to the withholding tax, but instead are subject to United States federal income tax on a net income basis at applicable graduated individual or corporate rates. Certain certification and disclosure requirements must be complied with in order for dividends to be exempt from withholding under such effectively connected income exemption. Any such effectively connected dividends received by a foreign corporation may be subject to an additional "branch profits tax" at a 30% rate or such lower rate as may be specified by an applicable income tax treaty. Until December 31, 1999, dividends paid to an address outside the United States are presumed to be paid to a resident of such country (unless the payer has knowledge to the contrary) for purposes of the withholding tax discussed above and, under the current interpretation of United States Treasury regulations, for purposes of determining the applicability of a tax treaty rate. However, a Non-U.S. Holder of common stock who wishes to claim the benefit of an applicable treaty rate (and avoid back-up withholding as discussed below) for dividends paid after December 31, 1999, will be required to satisfy applicable certification and other requirements. Special rules apply to dividend payments made after December 31, 1999 to foreign intermediaries, U.S. or foreign wholly- owned entities that are disregarded for U.S. federal income tax purposes and entities that are treated as fiscally transparent in the United States, the applicable income tax treaty jurisdiction, or both. In addition, U.S. tax legislation, effective August 4, 1997, denies income tax treaty benefits to foreigners receiving income derived through a partnership (or otherwise fiscally transparent entity) in certain circumstances. A Non-U.S. Holder of common stock eligible for a reduced rate of United States withholding tax pursuant to an income tax treaty may obtain a refund of any excess amounts withheld by filing an appropriate claim for refund with the Internal Revenue Service. GAIN ON DISPOSITION OF COMMON STOCK A Non-U.S. Holder generally will not be subject to United States federal income tax with respect to gain recognized on a sale or other disposition of common stock unless (i) the gain is 70

73 effectively connected with a trade or business of the Non-U.S. Holder in the United States and, where a tax treaty applies, is attributable to a United States permanent establishment of the Non-U.S. Holder, (ii) in the case of a Non-U.S. Holder who is an individual and holds the common stock as a capital asset, such holder is present in the United States for 183 or more days in the taxable year of the sale or other disposition and certain other conditions are met, (iii) the Non-U.S. Holder is subject to tax pursuant to the provisions of the U.S. tax law applicable to certain U.S. expatriates, (iv) we are or have been a "U.S. real property holding corporation" for United States federal income tax purposes, and the Non-U.S. Holder owned, directly or pursuant to certain attribution rules, more than 5% of WESCO's common stock at any time within the shorter of the five-year period preceding such disposition or such Non-U.S. Holder's holding period. WESCO believes it is not, and does not anticipate becoming, a "U.S. real property holding corporation" for United States federal income tax purposes. An individual Non-U.S. Holder described in clause (i) above will be subject to tax on the net gain derived from the sale under regular graduated United States federal income tax rates. An individual Non-U.S. Holder described in clause (ii) above will be subject to a flat 30% tax on the gain derived from the sale, which may be offset by United States source capital losses (even though the individual is not considered a resident of the United States). If a Non-U.S. Holder that is a foreign corporation falls under clause (i) above, it will be subject to tax on its gain under regular graduated United States federal income tax rates and, in addition, may be subject to the branch profits tax equal to 30% of its effectively connected earnings and profits within the meaning of the Code for the taxable year, as adjusted for certain items, unless it qualifies for a lower rate under an applicable income tax treaty. FEDERAL ESTATE TAX Common stock owned or treated as owned by an individual Non-U.S. Holder at the time of death will be included in such holder's gross estate for United States federal estate tax purposes, unless an applicable estate tax treaty provides otherwise. INFORMATION REPORTING AND BACKUP WITHHOLDING WESCO must report annually to the IRS and to each Non-U.S. Holder the amount of dividends paid to such Non-U.S. Holder and the tax withheld with respect to such dividends, regardless of whether withholding was required. Copies of the information returns reporting such dividends and withholding may also be made available to the tax authorities in the country in which the Non-U.S. Holder resides under the provisions of an applicable income tax treaty. Until December 31, 1999, backup withholding generally will not apply to dividends paid to a Non-U.S. Holder at an address outside the United States (unless the payer has knowledge that the payee is a U.S. person). With respect to dividends paid after December 31, 1999, however, a Non-U.S. Holder will be subject to back-up withholding unless applicable certification requirements are met. Payment of the proceeds of a sale of common stock within the United States or conducted through certain U.S.-related financial intermediaries is subject to (i) information reporting, and (ii) backup withholding (other than payments made before January 1, 2000, by or through certain U.S.-related financial intermediaries), unless the beneficial owner certifies under penalties of perjury that it is a Non-U.S. Holder (and the payor does not have actual knowledge that the beneficial owner is a United States person) or the holder otherwise establishes an exemption. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against such holder's U.S. federal income tax liability provided the required information is furnished to the IRS. 71

Inc., Donaldson, Lufkin & Jenrette Securities Corporation, Goldman, Sachs & Co., Robert W. Baird & Co., Incorporated and ING Baring Furman Selz LLC are acting as representatives (the "U.S. Representatives"), have severally agreed, subject to the terms and conditions of the U.S. Underwriting Agreement, to purchase from WESCO, and WESCO has agreed to sell to each U.S. Underwriter, the aggregate number of shares of Common Stock set forth opposite the name of each such U.S. Underwriter below: NUMBER OF U.S. UNDERWRITERS SHARES ----------------- ---------- Lehman Brothers Inc.........................................

Baird & Co. Incorporated and Baring Brothers Limited, as agent for ING Bank NV are acting as lead managers (the "Lead Managers" and, together with the U.S. Representatives, the "Representatives"), have severally agreed, subject to the terms and conditions of the International Underwriting Agreement, to purchase from WESCO, and WESCO has agreed to sell to each International Manager, the aggregate number of shares of common stock set forth opposite the name of each International Manager below: NUMBER OF INTERNATIONAL MANAGERS SHARES ---------------------- ---------- Lehman Brothers International (Europe)...................... Bear, Stearns International Limited......................... DLJ Securities International................................ Goldman Sachs International................................. Robert W. Baird & Co. Incorporated.......................... Baring Brothers Limited, as agent for ING Bank NV........... ---------- Total.................................................. 1,945,000 ========== The U.S. Underwriting Agreement and the International Underwriting Agreement (together, the "Underwriting Agreements") provide that the obligations of the U.S. Underwriters and the International Managers to purchase shares of common stock are subject to certain conditions, and 72

75 that if any of the foregoing shares of common stock are purchased by the U.S. Underwriters pursuant to the U.S. Underwriting Agreement or by the International Managers pursuant to the International Underwriting Agreement: then all the shares of Common Stock agreed to be purchased by the U.S. Underwriters and the International Managers, as the case may be, pursuant to their respective underwriting agreements, must be so purchased. The offering price and underwriting discounts and commissions per share for the U.S. offering and the international offering are identical. The closing of the U.S. offering is a condition to the closing of the international offering and the closing of the international offering is a condition to the closing of the U.S. offering. The initial public offering price will be determined by negotiations between representatives of the underwriters and us and may not be indicative of prices that will prevail in the trading market. The Representatives have advised us that the U.S. Underwriters and the International Managers propose to offer the shares of common stock directly to the public at the public offering price set forth on the cover page of this prospectus, and to certain selected dealers (who may include the U.S. Underwriters and the International Managers) at such public offering price less a selling concession not in excess of $ per share. The selected dealers may reallow a concession not in excess of $ per share to certain brokers and dealers. After this offering, the public offering price, the concession to selected dealers and the reallowance may be changed by the U.S. Underwriters and the International Managers. We have agreed to indemnify, under certain circumstances, the U.S. Underwriters and the International Managers against certain liabilities, including liabilities under the Securities Act, and to contribute, under certain circumstances, to payments that the U.S. Underwriters and the International Managers may be required to make in respect thereof. We have granted to the U.S. Underwriters an option to purchase up to an aggregate additional shares of common stock and have granted to the International Managers an option to purchase up to additional shares of common stock, in each case exercisable solely to cover over-allotments, at the public offering price less the underwriting discounts and commissions shown on the cover page of this prospectus. Such options may be exercised at any time until days after the date of the Underwriting Agreements. To the extent that the over-allotment option is exercised, each U.S. Underwriter or International Manager, as the case may be, will be committed, subject to certain conditions, to purchase a number of additional shares of common stock proportionate to such U.S. Underwriter's or International Manager's initial commitment as indicated in the preceding tables. The U.S. Underwriters and the International Managers have entered into an Agreement Between U.S. Underwriters and International Managers pursuant to which each U.S. Underwriter has agreed that, as part of the distribution of the shares of common stock offered in the U.S. offering, (i) it is not purchasing any such shares for the account of anyone other than a U.S. Person (as defined below), and (ii) it has not offered or sold, will not offer, sell, resell or deliver, directly or indirectly, any such shares or distribute any prospectus relating to the U.S. offering to anyone other than a U.S. Person. In addition, pursuant to such agreement, each International Manager has agreed that, as part of the distribution of the shares of common stock offered in the international offering, (i) it is not purchasing any such shares for the account of a U.S. Person, and (ii) it has not offered or sold, and will not offer, sell, resell or deliver, directly or indirectly, any of such shares or distribute any prospectus relating to the international offering to any U.S. Person. The foregoing limitations do not apply to stabilization transactions or to certain other transactions specified in the Underwriting Agreements and the Agreement Between U.S. Underwriters and International Managers, including (i) certain purchases and sales between U.S. Underwriters and the International Managers, (ii) certain offers, sales, resales, deliveries or distributions to or through investment advisors or other persons exercising investment discretion, 73

76 (iii) purchases, offers or sales by a U.S. Underwriter who is also acting as an International Manager or by an International Manager who is also acting as a U.S. Underwriter and (iv) other transactions specifically approved by the U.S. Representatives and the Lead Managers. As used herein, the term "U.S. Person" means any resident or national of the United States or Canada, any corporation, partnership or other entity created or organized in or under the laws of the United States or Canada, or any estate or trust the income of which is subject to United States or Canadian federal income taxation regardless of the source. Pursuant to the Agreement Between the U.S. Underwriters and the International Managers, sales may be made between the U.S. Underwriters and the International Managers of such a number of shares of common stock as may be mutually agreed. The price of any shares so sold shall be the public offering price as then in effect for the shares of common stock being sold by the U.S. Underwriters and the International Managers less an amount equal to the selling concession allocable to such shares of common stock, unless otherwise determined by mutual agreement. To the extent that there are sales between the U.S. Underwriters and the International Managers pursuant to the Agreement Between the U.S. Underwriters and the International Managers the number of shares of common stock available for sale by the U.S. Underwriters or by the International Managers may be more or less than the amount specified on the cover page of the this prospectus. Until the distribution of the common stock is completed, rules of the SEC may limit the ability of the Underwriters and certain selling group members to bid for and purchase shares of common stock. As an exception to these rules, the Representatives are permitted to engage in certain transactions that stabilize the price of the common stock. Such transactions may consist of bids or purchases for the purpose of pegging, fixing or maintaining the price of the common stock. If the Underwriters create a short position in the common stock in connection with this offering (i.e., if they sell more shares of common stock than are set forth on the cover page of this prospectus), the Representatives may reduce that short position by purchasing common stock in the open market. The Representatives also may elect to reduce any short position by exercising all or part of the over-allotment options described herein. The Representatives may also impose a penalty bid on certain Underwriters and selling group members. This means that, if the Representatives purchase shares of common stock in the open market to reduce the Underwriters' short position or to stabilize the price of the common stock, they may reclaim the amount of the selling concession from the Underwriters and selling group members who sold those shares as part of this offering. In general, purchases of a security for the purpose of stabilization or to reduce a syndicate short position could cause the price of the security to be higher than it might otherwise be in the absence of such purchases. The imposition of a penalty bid might have an effect on the price of a security to the extent that it were to discourage resales of the security by purchasers in this offering. Neither WESCO nor any of the Underwriters makes any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the common stock. In addition, neither WESCO nor any of the Underwriters makes any representation that the Representatives will engage in such transactions or that such transactions, once commenced, will not be discontinued without notice. Each International Manager has represented and agreed that (i) it has not offered or sold and, prior to the date six months after the date of issue of the shares of common stock, will not offer or sell any shares of common stock to persons in the United Kingdom except to persons whose ordinary activities involve them in acquiring, holding, managing or disposing of investments (as principal or agent) for the purposes of their businesses or otherwise in circumstances which have not resulted and will not result in an offer to the public in the United Kingdom within the meaning of the Public 74

77 Offers of Securities Regulations 1995, (ii) it has complied and will comply with all applicable provisions of the Financial Services Act 1986 with respect to anything done by it in relation to the shares of common stock in, from or otherwise involving the United Kingdom and (iii) it has only issued or passed on, and will only issue or pass on to any person in the United Kingdom any document received by it in connection with the issue of the shares of common stock if that person is of a kind described in Article 11(3) of the Financial Services Act 1986 (Investment Advertisements) (Exemptions) Order 1996 or is a person to whom such document may otherwise be issued or passed upon. The common stock is expected to be listed on the NYSE under the symbol . who, after this offering, will own in the aggregate shares of common stock, for a period of 180 days from the date of this prospectus have agreed that they will not, subject to certain limited exceptions, directly or indirectly, offer, sell or otherwise dispose of any shares of common stock or any securities convertible into or exchangeable or exercisable for any such shares of common stock or enter into any derivative transaction with similar effect as a sale of common stock, without the prior written consent of Lehman Brothers Inc. The restrictions described in this paragraph do not apply to (i) the sale of common stock to the Underwriters in this offering, (ii) the issuance by WESCO of shares of common stock upon the exercise of an option or the conversion of a security outstanding as of the date of this prospectus, (iii) transactions by any person other than WESCO relating to shares of common stock or other securities acquired in open market transactions after the completion of this offering or (iv) the issuance by WESCO of shares of common stock pursuant to employee benefit plans, qualified stock option plans or other employee compensation existing on the date of this prospectus. Any offer of the shares of common stock in Canada will be made only pursuant to an exemption from the prospectus filing requirement and an exemption from the dealer registration requirement (where such an exemption is not available, offers shall be made only by a registered dealer) in the relevant Canadian jurisdiction where such offer is made. Purchasers of the shares of common stock offered hereby may be required to pay stamp taxes and other charges in accordance with the laws and practices of the country of purchase, in addition to the offering price set forth on the cover hereof. The U.S. Underwriters and the International Managers have informed WESCO that they do not intend to sell to, and therefore will not confirm the sales of shares of common stock offered hereby to any accounts over which they exercise discretionary authority in excess of 5% of shares offered by them. Lehman Brothers Inc. has provided investment banking, financial advisory and other services to us, for which services Lehman Brothers Inc. has received customary fees. DIRECTED SHARE PROGRAM At the request of WESCO, the Underwriters have reserved for sale, at the offering price, up to 7.5% of the shares of the common stock that will be offered by this prospectus for directors, officers and employees of WESCO. Certain purchasers of such reserved shares may be required to agree in writing not to sell, transfer, assign, pledge or hypothecate such shares for 180 days from their date of purchase. The number of shares of common stock available for sale to the general public will be reduced to the extent such persons purchase such reserved shares. Any reserved shares that are not so purchased will be offered by the underwriters to the general public on the same basis as the other shares offered hereby. 75

80 REPORT OF INDEPENDENT ACCOUNTANTS To the Stockholders and Board of Directors of WESCO International, Inc.: In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of operations, stockholders' equity and redeemable common stock and cash flows present fairly, in all material respects, the financial position of WESCO International, Inc. and subsidiaries at December 31, 1997 and 1998, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 1998 in conformity with generally accepted accounting principles. These financial statements are the responsibility of WESCO's management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these statements in accordance with generally accepted auditing standards which require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for the opinion expressed above. /s/ PricewaterhouseCoopers LLP 600 Grant Street Pittsburgh, Pennsylvania February 12, 1999, except for Note 22, as to which the date is March 3, 1999.

85 WESCO INTERNATIONAL, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 1. ORGANIZATION WESCO International, Inc. and its subsidiaries (collectively, "WESCO"), headquartered in Pittsburgh, Pennsylvania, is a full-line distributor of electrical supplies and equipment and is a provider of integrated supply procurement services. WESCO currently operates branch locations in the United States, Canada, Mexico, Puerto Rico, Guam, Singapore and the United Kingdom. Subsequent to the completion in June 1998 of a leveraged recapitalization (see Note 3), WESCO was substantially owned by an investor group led by affiliates of The Cypress Group L.L.C. ("Cypress") with WESCO's management retaining the remaining interest. On February 28, 1994, Clayton & Dubilier Private Equity Fund IV Limited Partnership, managed by Clayton, Dubilier & Rice ("CD&R"), formed WESCO Distribution, Inc. for the purpose of acquiring substantially all of the assets and certain liabilities of Westinghouse Electric Supply Company ("1994 Formation") from the former Westinghouse Electric Corporation ("Westinghouse"). 2. ACCOUNTING POLICIES Basis of Presentation The consolidated financial statements include the accounts of WESCO International, Inc. and all of its subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. The preparation of the consolidated financial statements in conformity with generally accepted accounting principles requires management to make certain estimates and assumptions. These may affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements. They may also affect the reported amounts of revenues and expenses during the reported period. Actual results could differ from these estimates upon subsequent resolution of some matters. Revenue Recognition Revenues are recognized at the time products are shipped or services are rendered. Cash Equivalents Cash equivalents are defined as highly liquid investments with original maturities of 90 days or less when purchased. Asset Securitization WESCO accounts for the securitization of accounts receivable in accordance with Statement of Financial Accounting Standards ("SFAS") No. 125 "Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities." At the time the receivables are sold the balances are removed from the balance sheet. SFAS No. 125 also requires retained interests in the transferred assets to be measured by allocating the previous carrying amount between the assets sold and retained interests, if any, based on their relative fair values at the date of transfer. F-7

86 Inventories Inventories primarily consist of merchandise purchased for resale and are stated at the lower of cost or market. Cost is determined principally under the average cost method. Property, Buildings and Equipment Property, buildings and equipment are recorded at cost. Depreciation expense is determined using the straight-line method over the estimated useful lives of the assets. Leasehold improvements are amortized over either their respective lease terms or their estimated lives, whichever is shorter. Expenditures for new facilities and improvements that extend the useful life of an asset are capitalized. Ordinary repairs and maintenance are expensed as incurred. When property is retired or otherwise disposed of, the cost and the related accumulated depreciation are removed from the accounts and any related gains or losses are recorded. Intangible Assets Goodwill and other intangible assets arising from acquisitions are amortized on a straight-line basis over periods not exceeding 35 years. The carrying value of individual components of intangible assets are regularly reviewed by evaluating the estimated future undiscounted cash flows to determine recoverability of the assets. Any decrease in value is recognized on a current basis. Income Taxes Income taxes are accounted for under the liability method. Deferred tax assets and liabilities are determined based on differences between the financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. Valuation allowances, if any, are provided when a portion or all of a deferred tax asset may not be realized. Earnings Per Share Basic earnings per share are computed by dividing net income by the weighted-average common shares outstanding during the respective periods. Diluted earnings per share are computed by dividing net income by the weighted-average common shares and common share equivalents outstanding during the period. The dilutive effect of common share equivalents is considered in the diluted earnings per share computation using the treasury stock method. Foreign Currency Translation The local currency is the functional currency for substantially all of WESCO's operations outside the United States. Assets and liabilities of these operations are translated to U.S. dollars at the exchange rate in effect at each period end. Income statement accounts are translated at the average exchange rate prevailing during the period. Translation adjustments arising from the use of differing exchange rates from period to period are included as a component of stockholders' equity. Gains and losses from foreign currency transactions are included in net income for the period. Financial Instruments Periodically, WESCO enters into interest rate cap, floor and collar agreements to mitigate the exposure changes in interest rates have on variable-rate borrowings. If the requirements for hedge accounting are met, amounts paid or received under these agreements are recognized over the life of the agreements as adjustments to interest expense. Otherwise, the instruments are marked to market and the gains and losses from changes in the market value of the contracts are recorded in the F-8

87 current period. These financial instruments did not have a material impact on WESCO's consolidated financial statements for the three years ended December 31, 1998. Environmental Expenditures WESCO has facilities and operations which distribute certain products that must comply with environmental regulations and laws. Expenditures for current operations are expensed or capitalized, as appropriate. Expenditures relating to existing conditions caused by past operations, and which do not contribute to future revenue, are expensed. Liabilities are recorded when remedial efforts are probable and the costs can be reasonably estimated. Reclassifications Certain prior year amounts have been reclassified in order to conform with the current presentations. Recent Accounting Pronouncements In April 1998, the American Institute of Certified Public Accountants issued Statement of Position 98-5, "Reporting on the Costs of Start-Up Activities." This statement, which is effective for fiscal years beginning after December 15, 1998, requires costs incurred to open a new facility, introduce a new product, commence a new operation or other similar activities to be expensed as incurred. Management does not expect this statement will have a material impact on the results of operations and financial position. In June 1998, The Financial Accounting Standards Board issued SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities." This statement is effective in fiscal years beginning after June 15, 1999, although early adoption is permitted. This Statement requires the recognition of the fair value of any derivative financial instrument on the balance sheet. Changes in fair value of the derivative and, in certain instances, changes in the fair value of an underlying hedged asset or liability, are recognized through either income or as a component of other comprehensive income. Management does not expect this Statement will have a material impact on the results of operation or financial position of WESCO. 3. RECAPITALIZATION On June 5, 1998, WESCO repurchased and retired all of the common stock of WESCO held by CD&R (833,280 shares), Westinghouse (200,000 shares), and certain other management and nonmanagement stockholders (36,998 shares). All shares were issued and repurchased at $621.08 per share for net consideration of approximately $653.5 million ("Equity Consideration"). In addition, WESCO repaid approximately $379.1 million of then outstanding indebtedness, and sold 512,186 shares of common stock to an investor group led by affiliates of Cypress at $621.08 per share representing approximately 88.7% of WESCO for an aggregate cash consideration of $318.1 million ("Cash Equity Contribution") (collectively, "Recapitalization"). Existing management retained approximately 11.3% interest in WESCO after the Recapitalization. WESCO funded the Equity Consideration and the repayment of indebtedness from proceeds of the Cash Equity Contribution, issuance of approximately $351 million of Senior Subordinated and Senior Discount Notes, a new $170 million credit facility and the sale of approximately $250 million of accounts receivable. Given the 11.3% retained ownership, the transaction was treated as a recapitalization for financial reporting purposes and, accordingly, the historical bases of WESCO's assets and liabilities were not affected. In connection with the Recapitalization, WESCO recorded a one-time charge of $51.8 million related to compensation charges of $11.3 million associated with one-time bonuses paid to certain members of management, compensation charges of $6.2 million associated with the cash settlement F-9

88 of certain stock options, compensation charges of $4.1 million associated with the acceleration of vesting of one former executive's stock options issued at a discount, and non-capitalized transaction fees and expenses amounting to $30.2 million. 4. ACCOUNTS RECEIVABLE SECURITIZATION WESCO and certain of its subsidiaries entered into an agreement with a financial institution and a multi-seller asset-backed commercial paper issuer ("Receivables Facility") whereby it sells on a continuous basis an undivided interest in all eligible accounts receivable while maintaining a subordinated interest in a portion of the receivables. WESCO has agreed to continue servicing the sold receivables for the financial institution at market rates; accordingly, no servicing asset or liability has been recorded. Pursuant to the Receivables Facility, WESCO formed WESCO Receivables Corporation, a wholly-owned, special purpose, bankruptcy-remote subsidiary ("SPC"). SPC was formed to purchase, on a revolving basis and not to exceed $300 million, trade accounts receivables generated by certain subsidiaries of WESCO. WESCO may, under certain circumstances, increase the size of the Receivables Facility when the amount of eligible trade accounts receivables exceeds $300 million. The SPC will transfer to a trust all the receivables and the commercial paper issuer will provide financing to pay the purchase price of the receivables. As of December 31, 1998, securitized accounts receivable totaled $360.1 million, of which the subordinated retained interest was $84.1 million. Accordingly, $276 million of accounts receivable balances were removed from the consolidated balance sheet. Net proceeds from the transactions totaled $274.2 million. Proceeds from securitized receivables were used primarily to complete the Recapitalization discussed in Note 3 and for general working capital needs. During 1998, WESCO incurred costs associated with the Receivables Facility of $10.1 million, primarily related to the discount and loss on the sale of such receivables, partially offset by related servicing revenue. This amount is recorded as other expenses in the consolidated statement of operations. 5. ACQUISITIONS On September 11, 1998, WESCO acquired substantially all the assets and assumed substantially all liabilities and obligations relating to the operations of Bruckner Supply Company, Inc. ("Bruckner"), a privately owned company headquartered in Port Washington, New York. Bruckner is a provider of integrated supply procurement and outsourcing activities for large industrial companies. Net sales totaled approximately $222 million in 1997. The Bruckner purchase price at closing was $99.1 million, consisting of $72.5 million in cash and a noninterest bearing convertible note discounted to a value of $26.6 million for financial reporting purposes, resulting in goodwill of $88.0 million. The Bruckner purchase agreement provided for certain post-closing adjustments, which were paid in December 1998 and totaled $6.0 million. The agreement also provides for additional contingent consideration, not to exceed $130 million, of which $30 million was payable and recorded in other current liabilities at December 31, 1998, to be paid based on a multiple of increases in earnings before interest, taxes, depreciation and amortization of Bruckner with respect to calendar years 1998 through 2004. Following an initial public offering, up to 50% of the additional contingent consideration, if any, may be converted at the election of the holder into Class A common stock at the then market value. In January 1998 WESCO acquired the electrical distribution businesses of Avon Electric Supplies, Inc. and its affiliates ("Avon"). Net sales totaled approximately $85 million in 1997. F-10

89 The following unaudited pro forma information assumes that the Bruckner and Avon acquisitions had occurred at the beginning of each period presented. Adjustments to arrive at the pro forma information include, among others, those related to acquisition financing, amortization of goodwill and the related tax effects of such adjustments at an assumed rate of 39%. YEAR ENDED DECEMBER 31 ---------------------------------- 1997 1998 ------------- ------------- (UNAUDITED) (IN THOUSANDS, EXCEPT SHARE DATA) Sales, net................................................. $2,901,725 $3,205,333 Net income (loss).......................................... 41,551 (3,102) Basic earnings (loss) per share............................ 35.48 (3.98) Diluted earnings (loss) per share.......................... 30.07 (3.98) The pro forma financial information does not purport to present what WESCO's results of operations would have been if the Bruckner and Avon acquisitions had actually occurred at the beginning of each period presented, or to project WESCO's results of operations for any future period. In addition to the Bruckner and Avon acquisitions, WESCO acquired four other distributors in 1998, the largest of which were Brown Wholesale Electric Company (acquired January 1998) and Reily Electric Supply, Inc. (acquired May 1998). In 1996 and 1997 combined, WESCO acquired nine distributors. A summary of certain information with respect to all acquisitions follows: YEAR ENDED DECEMBER 31 ------------------------------- 1996 1997 1998 -------- ------- -------- (IN THOUSANDS) Aggregate purchase price................................ $110,597 $16,164 $250,218 Recorded goodwill....................................... 59,766 5,913 162,743 All of the acquisitions were accounted for under the purchase method of accounting for business combinations. The results of operations of these companies are included in the consolidated financial statements prospectively from the acquisition dates. Pro forma results of these acquisitions, excluding Bruckner and Avon, assuming they had been made at the beginning of each year presented, would not be materially different from the consolidated results reported herein. 6. CONCENTRATIONS OF CREDIT RISK AND SIGNIFICANT SUPPLIERS WESCO distributes its products and services and extends credit to a large number of customers in the industrial, construction, utility and manufactured structures markets. In addition, one supplier accounted for approximately 18%, 18% and 15% of WESCO's purchases for each of the three years in the period ended December 31, 1998, respectively. F-11

Investment in and advances to affiliate represents WESCO's investment in and amounts due from an unconsolidated equity-owned affiliate. Restricted cash represented proceeds received from the sale of properties that collateralized certain mortgage notes. Such mortgage notes were repaid in connection with the Recapitalization. F-12

LONG TERM DEBT The following table sets forth WESCO's outstanding indebtedness: DECEMBER 31 -------------------- 1997 1998 -------- -------- (IN THOUSANDS) Term loans.................................................. -- $169,500 Revolving facility.......................................... -- 42,450 Old revolving facility...................................... $226,145 -- Senior subordinated notes (1)............................... -- 289,194 Senior discount notes (2)................................... -- 52,071 Mortgage notes (3).......................................... 65,291 -- Other....................................................... 3,730 42,615 -------- -------- 295,166 595,830 Less current portion........................................ (891) (16,592) -------- -------- $294,275 $579,238 ======== ======== - ------------------------- (1) Net of original issue discount of $918 and purchase discount of $9,888 (2) Net of original issue discount of $33,266 and purchase discount of $1,664 (3) Net of original issue discount of $16,601 In connection with the Recapitalization, the old revolving facility and the mortgage notes were repaid. The old revolving facility was pursuant to credit agreements with various banks that provided for an aggregate $360 million of revolving credit facilities maturing in February 2000. This facility provided variable-rate borrowings tied to market indexes plus a fixed margin. The mortgage notes consisted of a zero coupon First Mortgage Note due February 2001 and an 8.0% First Mortgage Note due February 2001, each held by Westinghouse. The term loans and revolving facility borrowings were made pursuant to a credit agreement ("Credit Agreement") entered into by and between WESCO Distribution, Inc., ("WESCO Distribution") a wholly owned subsidiary of WESCO and certain financial institutions. The Credit Agreement provides for three term loan facilities in an aggregate principal amount of $270 million, consisting of Tranche A Term Loan, Tranche B Term Loan and a Delayed Draw Term Loan Facility, and a $100 million Revolving Credit Facility. Tranche A Term Loan provides for aggregate borrowings of $80 million, Tranche B Term Loan provides for aggregate borrowings of $90 million and the Delayed Draw Term Loan Facility provides for up to $100 million aggregate principal. The term loan facilities mature in various periods from 2004 through 2006. The Revolving Credit Facility provides for up to $100 million of revolving credit denominated in U.S. dollars or Canadian dollars. The maximum Canadian sublimit is approximately $46 million. The Revolving Credit Facility matures in 2004. Borrowings under the Credit Agreement are guaranteed by WESCO and are collateralized by substantially all the assets of WESCO and bear rates of interest equal to various indices, at WESCO's option, such as LIBOR, prime rate or the Federal Funds rate, plus a borrowing margin based on WESCO's financial performance. At December 31, 1998, the interest rate on Tranche A Term Loan, Tranche B Term Loan and the Revolving Credit Facility was 7.6%, 7.8% and 8.3%, respectively. In addition, WESCO has a 0.5% commitment fee on the unused commitments under the Revolving Credit Facility and the Delayed Draw Term Loan Facility. F-13

92 At December 31, 1998, WESCO has four interest rate cap and two interest rate collar agreements with aggregate notional amounts of $205 million that expire at various times between August 1999 and February 2000. The aggregate cost of these agreements of $0.2 million is being amortized to interest expense on a straight-line basis over the period of the agreements. The agreements effectively provide a ceiling for LIBOR at 7.0% and, with respect to $50 million notional value of interest rate collars, a floor of 4.5%. The market value of the interest rate caps and collars approximates the carrying value at December 31, 1998. The Senior Subordinated Notes in an aggregate principal amount of $300 million were issued by WESCO Distribution. The notes are unsecured obligations and are fully and unconditionally guaranteed by WESCO. The Senior Subordinated Notes bear interest at 9 1/8%, payable semiannually on June 1 and December 1 beginning December 1, 1998. The notes are due June 1, 2008. The Senior Subordinated Notes are redeemable by WESCO Distribution at any time prior to June 1, 2001, up to a maximum of 35% of the original aggregate principal amount of the Senior Subordinated Notes, with proceeds of an equity offering at a redemption price equal to 109.125% of the principal amount provided plus accrued and unpaid interest. In addition, the Senior Subordinated Notes are redeemable at the option of WESCO Distribution, in whole or in part, at any time after June 1, 2003 at the following prices: REDEMPTION PRICE ---------------- 2003.................................................. 104.563% 2004.................................................. 103.042 2005.................................................. 101.521 2006 and thereafter................................... 100.000 At any time prior to June 1, 2003, the Senior Subordinated Notes may be redeemed, in whole but not in part, at the option of WESCO at any time within 180 days after a change of control, at a redemption price equal to the principal amount thereof plus accrued and unpaid interest and the then applicable premium. In addition, the noteholders have the right to require WESCO, upon a change of control, to repurchase all or any part of the Senior Subordinated Notes at a redemption price equal to 101% of the principal amount provided plus accrued and unpaid interest. The Senior Discount Notes, issued by WESCO, have an aggregate principal amount of $87 million. The notes were issued with an original issue discount of $36.5 million that is being accreted over the period ending June 1, 2003. Beginning June 1, 2003, interest accrues at 11 1/8% payable semiannually on June 1 and December 1. At any time prior to June 1, 2001, WESCO may redeem, in whole but not in part, the Senior Discount Notes with the proceeds of an equity offering at a redemption price equal to 111.125% of the accreted value at the date of redemption. Approximately 35% of the then outstanding Senior Discount Notes ($30.9 million at December 31, 1998) must be redeemed on June 1, 2003. The remaining notes are due June 1, 2008 and are redeemable at the option of WESCO, in whole or in part, at any time after June 1, 2003 at the following prices: REDEMPTION PRICE ---------------- 2003.................................................. 105.563% 2004.................................................. 103.708 2005.................................................. 101.854 2006 and thereafter................................... 100.000 F-14

93 At any time prior to June 1, 2003, the Senior Discount Notes may be redeemed, in whole but not in part, at the option of WESCO at any time within 180 days after a change of control, at a redemption price equal to 100% of the accreted value to the redemption date plus the then applicable premium. In addition, the noteholders have the right to require WESCO, upon a change of control, to repurchase all or any part of the Senior Discount Notes at a redemption price equal to 101% of the accreted value prior to June 1, 2003 or 101% of the principal amount plus accrued and unpaid interest if after June 1, 2003. At December 31, 1997 and 1998, other borrowings primarily consist of notes issued to sellers in connection with acquisitions, of which $2 million and $37 million, respectively, are convertible into common stock at an initial public equity offering price. The following table sets forth the aggregate principal repayment requirements for all indebtedness for the next five years: (IN THOUSANDS) 1999.................................................... $16,871 2000.................................................... 40,736 2001.................................................... 13,071 2002.................................................... 16,530 2003.................................................... 51,412 The credit agreements contain various restrictive covenants that, among other things, impose limitations on (i) dividend payments or certain other restricted payments or investments; (ii) the incurrence of additional indebtedness and guarantees or issuance of additional stock; (iii) creation of liens; (iv) mergers, consolidation or sales of substantially all of WESCO's assets (v) certain transactions among affiliates; (vi) payments by certain subsidiaries to WESCO; and (vii) capital expenditures. In addition, the agreements require WESCO to meet certain leverage, working capital and interest coverage ratios. WESCO is permitted to pay dividends under certain limited circumstances. At December 31, 1997 and 1998, no retained earnings were available for dividend payments. Based on current market interest rates and discounted cash flow analyses, the fair value of WESCO's long-term debt approximates its carrying value at December 31, 1997 and 1998. WESCO had $3.3 million and $4.5 million of outstanding letters of credit at December 31, 1997 and 1998, respectively. These letters of credit are used as collateral for performance and bid bonds. The value of the letters of credit approximates the contract value. 10. OTHER CURRENT LIABILITIES The following table sets forth the components of other current liabilities: DECEMBER 31 ------------------ 1997 1998 ------- ------- (IN THOUSANDS) Accrued taxes other than income..................... $10,696 $12,466 Accrued interest.................................... 1,508 4,986 Deferred acquisition payable........................ -- 30,000 Other............................................... 7,950 4,219 ------- ------- $20,154 $51,671 ======= ======= F-15

94 11. CAPITAL STOCK Common Stock There are 2,000,000 shares each of Class A and Class B common stock authorized at a par value of $.01 per share. The Class B common stock is identical to the Class A common stock, except for voting and conversion rights. The holders of Class B common stock have no voting rights. With certain exceptions, Class B common stock may be converted, at the option of the holder, into the same number of shares of Class A common stock. No Class B common stock was outstanding at December 31, 1997. Redeemable Class A Common Stock Certain employees and key management of WESCO who hold Class A common stock and options may require WESCO to repurchase, under certain conditions, death, disability or termination without cause during the term of employment, all of the shares and the exercisable portion of the options held. This repurchase right terminates upon the consummation of an initial equity public offering of WESCO's Class A common stock. In connection with the redemption features described above, WESCO has classified outside of permanent equity an amount representing the initial fair value of the redeemable shares. These shares and exercisable options have not been marked to market since the events of redemption are considered remote. The following table sets forth capital stock share activity: REDEEMABLE CLASS A CLASS B CLASS A -------- ------- ---------- December 31, 1995..................................... 933,280 -- 79,904 Options exercised..................................... -- -- 3,428 Shares issued......................................... -- -- 4,750 -------- ------ ------- December 31, 1996..................................... 933,280 88,082 Options exercised..................................... -- -- 1,714 Shares issued......................................... -- -- 800 Shares repurchased.................................... -- -- (1,290) -------- ------ ------- December 31, 1997..................................... 933,280 89,306 Recapitalization, net.................................

95 12. INCOME TAXES The following table sets forth the components of the provision for income taxes: YEAR ENDED DECEMBER 31 ---------------------------- 1996 1997 1998 ------- ------- ------ (IN THOUSANDS) Current taxes Federal.................................................. $15,360 $16,689 $5,037 State.................................................... 2,872 3,067 1,229 Foreign.................................................. 210 1,117 (117) ------- ------- ------ Total current......................................... 18,442 20,873 6,149 Deferred taxes Federal..................................................

(78) 2,837 2,370 ------- ------- ------ $18,364 $23,710 $8,519 ======= ======= ====== At the time of the 1994 Formation, WESCO had approximately $45 million of future tax deductions ($18 million of future tax benefits) that resulted in the creation of certain deferred tax assets. At that time, WESCO recorded a valuation allowance for the full amount of the deferred tax assets reflected on the opening balance sheet since the realization of the future tax benefits was not considered likely. However, at December 31, 1996, all of these deductions had been recognized as a reduction in noncurrent intangible assets. The charge in lieu of taxes recognized in 1996 represents the amount of tax expense that would have been recognized had the benefits described above been recorded at the time of the 1994 Formation. The following table sets forth the components of income before income taxes by jurisdiction: YEAR ENDED DECEMBER 31 ---------------------------- 1996 1997 1998 ------- ------- ------ (IN THOUSANDS) United States.............................................. $49,072 $57,083 $1,743 Canada..................................................... 1,754 2,864 (960) ------- ------- ------ $50,826 $59,947 $ 783 ======= ======= ====== F-17

As a result, WESCO recognized benefits of approximately $2.9 million associated with the realization of post formation deferred tax assets through the reversal of the associated valuation allowance. The following table sets forth deferred tax assets and liabilities: DECEMBER 31 -------------------- 1997 1998 -------- -------- (IN THOUSANDS) Accounts receivable......................................... $ 4,236 $ 6,330 Inventory................................................... 4,819 5,325 Other....................................................... 5,222 4,562 -------- -------- Deferred tax assets.................................... 14,277 16,217 -------- -------- Intangibles.................................................

EARNINGS PER SHARE The following table sets forth the details of basic and diluted earnings per share: YEAR ENDED DECEMBER 31 ----------------------------------- 1996 1997 1998 ---------- ---------- ------- (DOLLARS IN THOUSANDS, EXCEPT SHARE DATA) Net income (loss).................................... $ 32,462 $ 36,237 $(7,736) Interest on convertible debt......................... -- 125 -- ---------- ---------- ------- Net income (loss) used in diluted earnings per share.............................................. $ 32,462 $ 36,362 $(7,736) Weighted average common shares outstanding used in computing basic earnings (loss) per share.......... 1,015,238 1,021,282 779,440 Common shares issuable upon exercise of dilutive stock options...................................... 86,335 125,729 -- Assumed conversion of convertible debt............... -- 6,606 -- ---------- ---------- ------- Weighted average common shares outstanding and common share equivalents used in computing diluted earnings (loss) per share.......................... 1,101,573 1,153,617 779,440 ========== ========== ======= Basic earnings (loss) per share...................... $ 31.97 $ 35.48 $ (9.93) Diluted earnings (loss) per share.................... 29.47 31.52 (9.93) Interest on convertible debt of $1.3 million and common share equivalents outstanding in 1998 of 114,718 were anti-dilutive and, accordingly, were not considered in the computation of diluted loss per share for the year ended December 31, 1998. 14. EMPLOYEE BENEFIT PLANS A majority of WESCO's employees are covered by defined contribution retirement savings plans for their service rendered subsequent to the 1994 Formation. Westinghouse retained certain retiree pension and health benefits for service rendered prior to the 1994 Formation. U.S. employee contributions of not more than 6% of eligible compensation are matched 50% by WESCO. WESCO's contributions for Canadian employees range from 1% to 6% of eligible compensation based on years of service. In addition, employer contributions may be made at the discretion of the Board of Directors and can be based on WESCO's current year performance. Employees are credited for service with Westinghouse in determining the vesting of WESCO's contributions. For the years ended December 31, 1996, 1997 and 1998, WESCO contributed $9.3 million, $12.5 million and $14.1 million, respectively, which was charged to expense. 15. STOCK INCENTIVE PLANS Stock Purchase Plan. In connection with the Recapitalization, WESCO established a stock purchase plan ("1998 Stock Purchase Plan") under which certain employees may be granted an opportunity to purchase WESCO's Class A common stock. The maximum number of shares available for purchase may not exceed 7,400. The purchase price per share is determined by the Board of Directors of WESCO to represent fair market value, as defined by the Stock Subscription Agreement. Should the purchase price of the stock be less than the fair market value of the stock at the grant date, such excess will be F-19

98 recorded as compensation expense in the consolidated statements of operations. During 1998, 5,050 shares were issued at a weighted-average share price of $621. At the time of the 1994 Formation, WESCO established a stock purchase plan ("1994 Stock Purchase Plan") under which certain employees were granted an opportunity to purchase WESCO's Class A common stock. Future purchases of shares under the 1994 Stock Purchase Plan were terminated in conjunction with the establishment of the 1998 Stock Purchase Plan. Shares purchased under the 1994 Stock Purchase Plan in the periods indicated were as follows: YEAR ENDED DECEMBER 31 ------------------------ 1996 1997 1998 ------ ---- ------ Shares purchased............................................ 2,610 800 2,292 Weighted-average share price................................ $ 169 $251 $ 621 Other Stock Purchases. In addition, certain key management employees of WESCO, nonemployee directors and other investors may be granted an opportunity to purchase WESCO's Class A common stock. The purchase price per share is determined by the Board of Directors to represent the fair market value, as defined by the Stock Subscription Agreement. At December 31, 1997 and 1998, 54,150 shares and 73,792 shares, respectively, had been purchased. Other stock purchases in the periods indicated were as follows: YEAR ENDED DECEMBER 31 ------------------------- 1996 1997 1998 ------ ---- ------- Shares purchased............................................ 2,140 -- 19,642 Weighted-average share price................................ $ 195 -- $ 621 Stock Option Plans. WESCO has sponsored three stock options plans, the 1998 Stock Option Plan, the Stock Option Plan for Branch Employees (collectively "Stock Option Plans") and the 1994 Stock Option Plan. Participation is limited to executive and senior officers, certain other key employees and branch employees. The Stock Option Plans and the 1994 Stock Option Plan cover a maximum of 112,500 and 181,000 shares of WESCO's Class A common stock, respectively. The exercise price per share is determined by the Board of Directors to represent the fair market value, as defined by these plans, at the grant date. Options granted will vest and will become exercisable over periods ranging from four to five years or earlier based on WESCO achieving certain financial performance criteria, except in the event of a change in control. Each option terminates on the tenth anniversary of its grant date unless terminated sooner under certain conditions. The plans require WESCO to repurchase the exercisable portion of the options held by an employee if the employee dies, is disabled or terminated without cause during the term of employment. This repurchase right terminates upon consummation of an initial public equity offering of WESCO's Class A common stock. Since the triggering event requiring the repurchase is considered remote, WESCO accounts for the plans as fixed plans and, accordingly, no compensation expense has been recorded. In connection with the Recapitalization, future issuances of options under the 1994 Stock Option Plan were terminated and all options granted under the 1994 Stock Option Plan became fully vested. F-20

99 The following table sets forth shares of common stock reserved for future issuance at December 31, 1998: Stock Purchase Plan......................................... 2,350 Stock Option Plans.......................................... 27,607 The following table sets forth a summary of stock option activity and related information for the years indicated: 1996 1997 1998 ------------------------ ------------------------ ------------------------ WEIGHTED WEIGHTED WEIGHTED AVERAGE AVERAGE AVERAGE OPTIONS EXERCISE PRICE OPTIONS EXERCISE PRICE OPTIONS EXERCISE PRICE ------- -------------- ------- -------------- ------- -------------- Beginning of year.............. 95,970 $102 98,842 $107 119,844 $127 Granted (1).................... 6,300 181 26,140 198 72,100 565 Exercised......................

Of these options, 6,200 were subsequently exercised. The remaining 4,800 were forfeited and the associated costs were classified as additional capital. The Westinghouse option discussed in Note 16 is not included in the information set forth above. The following table sets forth exercise prices for options outstanding as of December 31, 1998: EXERCISE PRICE WEIGHTED AVERAGE PER OPTION OPTIONS REMAINING CONTRACTUAL LIFE - -------------- ------- -------------------------- 100$.00.... 63,148 5.6 years 114.30.... 12,431 7.0 195.40.... 27,913 8.0 250.97.... 1,040 8.9 621.08.... 61,100 9.6 In connection with the implementation of SFAS No. 123, "Accounting for Stock-Based Compensation," WESCO has elected to continue to account for stock-based compensation arrangements under the provisions of Accounting Principles Board (APB) Opinion No. 25. F-21

100 If compensation costs had been determined based on the fair value at the grant dates according to SFAS No. 123, WESCO's net income and earnings per share, would have been as follows: YEAR ENDED DECEMBER 31 ----------------------------- 1996 1997 1998 ------- ------- ------- (IN THOUSANDS, EXCEPT SHARE DATA) Net income (loss) As reported............................................. $32,462 $36,237 $(7,736) Pro forma............................................... 32,441 36,144 (8,629) Basic earnings (loss) per share As reported............................................. $ 31.97 $ 35.48 $ (9.93) Pro forma............................................... 31.95 35.39 (11.07) Diluted earnings (loss) per share As reported............................................. $ 29.47 $ 31.52 $ (9.93) Pro forma............................................... 29.45 31.44 (11.07) The weighted-average fair value per option granted was $16.70, $33.56 and $223.20, for the years ended December 31, 1996, 1997 and 1998, respectively. For purposes of presenting pro forma results, the fair value of each option grant is estimated on the date of grant using the Black-Scholes option-pricing model and the following assumptions: YEAR ENDED DECEMBER 31 ------------------------ 1996 1997 1998 ---- ---- ---- Risk-free interest rate..................................... 6.5% 6.5% 5.0% Expected life (years)....................................... 7 7 7 === === === 16. RELATED PARTIES Prior to the Recapitalization, Westinghouse was considered a related party. A summary of purchases from and sales to Westinghouse follows: YEAR ENDED DECEMBER 31 ---------------------------- 1996 1997 1998 ------- ------- ------ (IN THOUSANDS) Purchases from Westinghouse................................ $19,115 $15,498 $2,765 Sales to Westinghouse...................................... 21,192 21,666 7,271 ======= ======= ====== The amount due from Westinghouse at December 31, 1997, net of amounts owed was approximately $2.6 million. In connection with the 1994 Formation, WESCO granted Westinghouse an option to purchase 100,000 shares of Class A common stock at $100 per share. The fair value of this option, or $2.5 million, was included in the consolidated balance sheets as common stock to be issued under option. This option was exercised and the associated shares were repurchased in connection with the Recapitalization. In connection with the Recapitalization, WESCO paid Cypress $9.5 million related to transaction fees and WESCO received from CD&R $5.8 million as contributed capital. Prior to the F-22

101 Recapitalization, WESCO paid CD&R an annual financial advisory and management consulting fee of $0.4 million. 17. COMMITMENTS AND CONTINGENCIES Future minimum rental payments required under operating leases, primarily for real property that have noncancelable lease terms in excess of one year as of December 31, 1998, are as follows: (IN THOUSANDS) 1999........................................................ $17,827 2000........................................................ 15,677 2001........................................................ 13,399 2002........................................................ 9,083 2003........................................................ 5,034 Thereafter.................................................. 9,787 Rental expense for the years ended December 31, 1996, 1997 and 1998, was $22.0 million, $26.4 million and $29.1 million, respectively. WESCO has litigation arising from time to time in the normal course of business. In management's opinion, any present litigation WESCO is aware of will not materially affect WESCO's consolidated financial position, results of operations or cash flows. Westinghouse agreed to indemnify WESCO for certain environmental liabilities that existed at the time of the 1994 Formation. WESCO has made a claim under this indemnity amounting to $1.5 million. The ultimate resolution of this environmental compliance issue is not expected to materially impact WESCO's consolidated financial position, results of operations or cash flows. At December 31, 1998, WESCO has guaranteed $8.9 million in loans to certain stockholders. 18. SEGMENTS AND RELATED INFORMATION In 1998, WESCO adopted SFAS No. 131, "Disclosures about Segments of an Enterprise and Related Information." SFAS No. 131 established standards for disclosure of operating segments under the management approach. For purposes of this standard, WESCO is engaged principally in one line of business -- the sale of electrical products and maintenance repair and operating supplies -- which represents more than 95% of the consolidated sales, income from operations and assets, for the year ended December 31, 1998. The following table presents information about WESCO by geographic area. There were no material amounts of sales or transfers among geographic areas and no material amounts of United States export sales: YEAR ENDED DECEMBER 31 ---------------------------------------------------------------------- SALES, NET LONG-LIVED ASSETS ------------------------------------ ------------------------------ 1996 1997 1998 1996 1997 1998 ---------- ---------- ---------- -------- -------- -------- (IN THOUSANDS) United States.............. $1,993,995 $2,292,121 $2,713,213 $151,835 $161,250 $344,481 Canada..................... 258,739 280,812 272,463 12,733 11,962 10,483 Other...................... 21,888 21,886 39,763 147 810 1,889 ---------- ---------- ---------- -------- -------- -------- $2,274,622 $2,594,819 $3,025,439 $164,715 $174,022 $356,853 ========== ========== ========== ======== ======== ======== F-23

In connection with the Offering, certain employee rights to require WESCO to repurchase outstanding redeemable Common Stock will terminate, and WESCO also plans to reclassify its Class A Common Stock, par value $.01 per share, F-25

104 into Common Stock, par value $.01 per share. WESCO intends to use net proceeds from the Offering to retire all of the outstanding 11 1/8% Senior Discount Notes due 2008, to repay all of the existing indebtedness under the Revolving Credit Facility, and the remaining balance to repay a portion of the Tranche B Term Loan. If such indebtedness is repaid, WESCO would incur an extraordinary charge relating to the write-off of existing unamortized debt issue costs and payment of a premium associated with the retirement of the Senior Discount Notes. There can be no assurance as to the timing or completion of the Offering or as to the amount of net proceeds to be received by WESCO and applied to debt reduction as intended. F-26

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS. Under Section 145 of the DGCL, a corporation has the power to indemnify directors and officers under certain prescribed circumstances and subject to certain limitations against certain costs and expenses, including attorneys' fees actually and reasonably incurred in connection with any action, suit or proceeding, whether civil, criminal, administrative or investigative, to which any of them is a party by reason of his being a director or officer of the corporation if it is determined that he acted in accordance with the applicable standard of conduct set forth in such statutory provision. Article VI of our By-Laws provides that we will indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding by reason of the fact that he is or was a director, officer, employee or agent of WESCO, or is or was serving at the our request as a director, officer, employee or agent of another entity, against certain liabilities, costs and expenses. Article VI further permits us to maintain insurance on behalf of any person who is or was a director, officer, employee or agent of WESCO, or is or was serving at our request as a director, officer, employee or agent of another entity against any liability asserted against such person and incurred by such person in any such capacity or arising out of his status as such, whether or not we would have the power to indemnify such person against such liability under the DGCL. We maintain directors' and officers' liability insurance. Section 102(b)(7) of the Delaware General Corporation Law permits a corporation, in its certificate of incorporation, to limit or eliminate, subject to certain statutory limitations, the liability of directors to the corporation or its stockholders for monetary damages for breaches of fiduciary duty, except for liability (a) for any breach of the director's duty of loyalty to the corporation or its stockholders, (b) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (c) under Section 174 of the DGCL, or (d) for any transaction from which II-1

ITEM 17. UNDERTAKINGS. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue. The undersigned registrant hereby undertakes that: (1) For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective. (2) For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

Commerce Court, Suite 700 Four Station Square Pittsburgh, PA 15219 RE: REGISTRATION STATEMENT ON FORM S-1 (FILE NO. 333-73299) ---------------------------------- Dear Ladies and Gentlemen: We are acting as counsel to WESCO International, Inc., a Delaware corporation (the "Company"), in connection with the Registration Statement on Form S-1 (File No. 333-73299) filed with the Securities and Exchange Commission pursuant to the Securities Act of 1933, as amended, by the Company on March 3, 1999 and amended on April 9, 1999, (the "Registration Statement"). The Registration Statement relates to the public offering (the "Offering") of up to 9,725,000 shares (the "Shares") of the Company's Common Stock, $.01 par value (the "Common Stock"), including up to 1,458,750 Shares that the underwriters for whom Lehman Brothers Inc. is acting as the representatives (the "Underwriters") will have an option to purchase from the Company solely for the purpose of covering over-allotments. We are familiar with the Registration Statement. We have examined and are familiar with (i) the Company's Certificate of Incorporation; (ii) the Company's By-laws; [(iii) the Company's proposed Restated Certificate of Incorporation (the "New Certificate") in the form in which it is to be filed with the Secretary of State of the State of Delaware prior to the consummation of the Offering; (iv) the Company's proposed Restated By-laws (the "New By-laws") in the form in which they are proposed to become effective prior to the consummation of the Offering; and (v) the proceedings of the Board of Directors of the Company with respect to the approval and adoption of the New Certificate and the New By-laws. We have also examined such other documents, corporate records, certificates of public officials, instruments, statutes and questions of law as we deemed necessary or appropriate to enable us to express an informed opinion on the matters hereinafter set forth. In making such examinations and rendering the opinions on the matters set forth below, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to original documents

We express no opinion as to the laws of any jurisdiction other than the General Corporation Law of the State of Delaware or as to any laws of the United States of America other than the Securities Act of 1933, as amended. Based upon and subject to the foregoing and subject to the filing of the New Certificate with the Secretary of State of the State of Delaware, and the General Corporation Law of the State of Delaware, we are of the opinion that: (a) The Company has been duly organized and is validly existing under the laws of the State of Delaware. (b) The Shares, when issued and sold in accordance with the plan of distribution set forth in the Registration Statement, will be validly issued, fully paid and non-assessable.
