WESCO INTERNATIONAL, INC. AND SUBSIDIARIES NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (unaudited) 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 is engaged principally in one line of business - the sale of electrical products and maintenance, repair and operating supplies. WESCO currently operates over 350 branch locations and five distribution centers in the United States, Canada, Mexico, Puerto Rico, Guam, the United Kingdom, Nigeria and Singapore. 2. ACCOUNTING POLICIES Basis of Presentation The unaudited condensed consolidated financial statements include the accounts of WESCO and all of its subsidiaries and have been prepared in accordance with Rule 10-01 of the Securities and Exchange Commission. The unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in WESCO's 2002 Annual Report on Form 10-K filed with the Securities and Exchange Commission. The unaudited condensed consolidated balance sheet as of June 30, 2003, the unaudited condensed consolidated statements of operations for the three months and six months ended June 30, 2003 and June 30, 2002 and the unaudited condensed consolidated statements of cash flows for the six months ended June 30 2003 and June 30, 2002, in the opinion of management, have been prepared on the same basis as the audited consolidated financial statements and include all adjustments necessary for the fair presentation of the results of the interim periods. All adjustments reflected in the condensed consolidated financial statements are of a normal recurring nature unless indicated. Results for the interim periods presented are not necessarily indicative of the results to be expected for the full year. Goodwill Annually, goodwill is tested for impairment as of October 1 or sooner if events or circumstances occur indicating that goodwill might be impaired. No impairment losses were identified as a result of past reviews. Stock Options WESCO accounts for stock-based compensation arrangements under the recognition and measurement principles of APB Opinion No. 25, "Accounting for Stock Issued to Employees," ("APB 25") and related interpretations. WESCO currently records compensation expense for its stock options utilizing the intrinsic value method in accordance with APB 25. No stock-based employee compensation cost has been reflected in net income, as all options granted in the six months ended June 30, 2003 and 2002 had an exercise price equal to the market value of the underlying common stock on the date of grant. The following table illustrates the effect on net income and earnings per share if WESCO had applied the fair value recognition provisions of SFAS No. 123, "Accounting for Stock-Based Compensation," to measure stock-based compensation for past awards: 5

Recent Accounting Pronouncements In December 2002, the FASB issued SFAS No. 148, "Accounting for Stock-Based Compensation -- Transition and Disclosure -- an amendment of SFAS No. 123." SFAS No. 148 was issued to provide alternative methods of transition for a voluntary change to the fair-value-based method of accounting for stock-based employee compensation. In addition, this statement amends the disclosure requirements of SFAS No. 123 to require prominent disclosures in both annual and interim financial statements about the method of accounting for stock-based employee compensation and the effect of the method used on reported results. The amendments to SFAS No. 123 in paragraphs 2(a)-2(e) of this statement shall be effective for financial statements for fiscal years ending after December 15, 2002. Currently, WESCO is evaluating the impact of adopting the fair-value-based method of accounting for stock-based compensation under SFAS No. 148. Effective June 30, 2003, WESCO adopted SFAS No. 149, "Amendment of Statement 133 on Derivative Instruments and Hedging Activities." This statement amends and clarifies financial accounting and reporting for derivatives and for hedging activities under SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities." This standard had no impact on WESCO's financial statements. In May 2003, the FASB issued SFAS No. 150, "Accounting for Certain Instruments with Characteristics of Both Liabilities and Equity." This standard requires that certain financial instruments embodying an obligation to transfer assets or to issue equity securities be classified as liabilities. It is effective for financial instruments entered into or modified after May 31, 2003, and otherwise is effective July 1, 2003. This standard had no impact on WESCO's financial statements. In November 2002, the FASB issued Interpretation No. 45, "Guarantor's Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others," which elaborates on the disclosures to be made by a guarantor in its interim and annual financial statements about its obligations under certain guarantees that it has issued. It also clarifies that a guarantor is required to recognize, at the inception of a guarantee, a liability for the fair value of the obligation undertaken in issuing the guarantee. This interpretation does not prescribe a specific approach for subsequently measuring the guarantor's recognized liability over the term of the related guarantee. This interpretation also incorporates, without change, the guidance in FASB Interpretation No. 34, "Disclosure of Indirect Guarantees of Indebtedness of Others," which is being superseded. The initial recognition and initial measurement provisions of this interpretation are applicable on a prospective basis to 6

guarantees issued or modified beginning January 1, 2003. The adoption of this statement did not have a material impact on WESCO's financial statements. In January 2003, the FASB issued Interpretation No. 46, "Consolidation of Variable Interest Entities." This interpretation requires unconsolidated variable interest entities to be consolidated by their primary beneficiaries if the entities do not effectively disperse the risk and rewards of ownership among their owners and other parties involved. The provisions of this interpretation are effective immediately to all variable interest entities created after January 1, 2003 and variable interest entities in which an enterprise obtains an interest in after that date. For variable interest entities created before this date, the provisions are effective July 31, 2003. WESCO does not believe the adoption of this interpretation will have a material impact on its consolidated financial statements. 3. EARNINGS PER SHARE The following table sets forth the details of basic and diluted earnings per share: THREE MONTHS ENDED JUNE 30 Dollars in thousands, except per share amounts 2003 2002 ------------------------------------------------------------------------------------------ Reported net income $7,350 $5,573 ======================= Weighted average common shares outstanding used in computing basic earnings per share 45,114,271 45,033,911 Common shares issuable upon exercise of dilutive stock options 1,429,219 2,042,889 ----------------------- Weighted average common shares outstanding and common share equivalents used in computing diluted earnings per share 46,543,490 47,076,800 ======================= Earnings per share: Basic $0.16 $0.12 Diluted $0.16 $0.12 ------------------------------------------------------------------------------------------ SIX MONTHS ENDED JUNE 30 Dollars in thousands, except per share amounts 2003 2002 ------------------------------------------------------------------------------------------ Reported net income $12,189 $9,411 ======================= Weighted average common shares outstanding used in computing basic earnings per share 45,111,131 44,966,322 Common shares issuable upon exercise of dilutive stock options 1,371,041 2,001,988 ----------------------- Weighted average common shares outstanding and common share equivalents used in computing diluted earnings per share 46,482,172 46,968,310 ======================= Earnings per share: Basic $0.27 $0.21 Diluted $0.26 $0.20 ------------------------------------------------------------------------------------------ 4. ACCOUNTS RECEIVABLE SECURITIZATION WESCO maintains an accounts receivable securitization program ("Receivables Facility") that requires annual renewal. Under the Receivables Facility, WESCO sells, on a continuous basis, to WESCO Receivables Corporation, a wholly-owned, special purpose company ("SPC"), an undivided interest in all domestic accounts receivable. The SPC sells without recourse to a third-party conduit all the eligible receivables while maintaining a subordinated interest, in the form of overcollateralization, 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. As of June 30, 2003 and December 31, 2002, securitized accounts receivable totaled approximately $361 million and $346 million, respectively, of which the subordinated retained interest was approximately $136 million and $53 million, respectively. Accordingly, approximately $225 million and $293 million of accounts receivable 7

balances were removed from the consolidated balance sheets at June 30, 2003 and December 31, 2002, respectively. WESCO reduced its accounts receivable securitization program by $68 million in 2003. Costs associated with the Receivables Facility totaled $1.3 million and $1.7 million for the three months ended June 30, 2003 and June 30, 2002. Costs associated with the Receivables Facility totaled $2.7 million and $3.1 million for the six months ended June 30, 2003 and June 30, 2002. These amounts are recorded as other expenses in the consolidated statements of operations and are primarily related to the discount and loss on the sale of accounts receivables, partially offset by related servicing revenue. The key economic assumptions used to measure the retained interest at the date of the securitization for securitizations completed in 2003 were a discount rate of 2% and an estimated life of 1.5 months. At June 30, 2003, an immediate adverse change in the discount rate or estimated life of 10% and 20% would result in a reduction in the fair value of the retained interest of $0.1 million and $0.2 million, respectively. These sensitivities are hypothetical and should be used with caution. As the figures indicate, changes in fair value based on a 10% variation in assumptions generally cannot be extrapolated because the relationship of the change in assumption to the change in fair value may not be linear. Also, in this example, the effect of a variation in a particular assumption on the fair value of the retained interest is calculated without changing any other assumption. In reality, changes in one factor may result in changes in another. On June 28, 2003, this facility was extended until August 31, 2003 with a total purchase commitment of up to $242 million. The Company expects to enter into a similar facility with a purchase commitment of up to $350 million before the expiration date of the current facility. This new structure is expected to include the addition of a three-year commitment of up to $150 million that will minimize the amount that is subject to an annual renewal. 5. COMPREHENSIVE INCOME The following table sets forth comprehensive income and its components: THREE MONTHS ENDED JUNE 30 In thousands 2003 2002 ------------------------------------------------------------------- Net income $7,350 $5,573 Foreign currency translation adjustment 4,320 2,240 --------------------- Comprehensive income $11,670 $7,813 ------------------------------------------------------------------- ------------------------------------------------------------------- SIX MONTHS ENDED JUNE 30 In thousands 2003 2002 ------------------------------------------------------------------- Net income $12,189 $9,411 Foreign currency translation adjustment 7,210 2,191 --------------------- Comprehensive income $19,399 $11,602 ------------------------------------------------------------------- 6. ACQUISITIONS Certain of our acquisition agreements contain earn-out provisions based principally on future earnings targets. The most significant of these agreements relates to the acquisition of Bruckner Supply Company, which provides for an earn-out potential of $80 million during either one of the next two years if certain earnings targets are achieved. The amount of earn-out proceeds earned that is payable in any single year is capped under this agreement at $30 million per year. Certain other acquisitions also contain contingent consideration provisions, only one of which could require a significant payment. Management estimates this payment could range from $0 to $20 million and would be made in 2008. The following table sets forth supplemental cash flow information with respect to acquisitions: SIX MONTHS ENDED JUNE 30, In thousands 2003 2002 -------------------------------------------------------------------- Details of acquisitions: Deferred acquisition payments $2,528 $10,741 ---------------------- Cash paid for acquisitions $2,528 $10,741 -------------------------------------------------------------------- 8

7. LONG-TERM DEBT In March 2003, WESCO successfully completed a series of mortgage financings which totaled $51 million. Total borrowings under the mortgage financing are subject to a 22-year amortization schedule with a balloon payment due at the end of the 10-year term. Proceeds from the borrowings were used to reduce outstanding borrowing under the 2002 Revolving Credit Facility. Interest rates on borrowings under this facility are fixed at 6.5%. During the six months ended June 30, 2003, the Company's interest rate swap agreements were settled and as a result the Company received $4.6 million. The gain resulting from the settlement of these agreements has been deferred and is being amortized as a reduction of interest expense over the remaining life of the senior subordinated notes. 8. INCOME TAXES The following table sets forth the reconciliation between the federal statutory income tax rate and the effective rate: THREE MONTHS ENDED JUNE 30, ---------------------- 2003 2002 ---------------------- Federal statutory rate.................................... 35.0% 35.0% State taxes, net of federal tax benefit................... 0.2 1.4 Nondeductible expenses.................................... 2.3 1.7 Foreign taxes, credits and exclusions.....................

(4.0) -- ---------------------- 12.5% 31.7% ====================== - ------------------------------ (1) Represents a $1.4 million benefit from a change in a tax accounting method and $1.0 from the reversal of a prior tax contingency reserve. (2) Reflects a decrease in the rate applied to deferred tax items. Management believes this revised estimate reflects the rate that will be in effect when these items reverse. (3) Represents the recognition of a $0.6 million benefit associated with the utilization of a net operating loss. 9. SELLING GENERAL AND ADMINISTRATIVE EXPENSE Selling general and administrative ("SG&A") expenses for the three and six months ended June 30, 2003 include $5.7 million and $8.1 million, respectively, associated with discretionary retirement plan contributions and out of the ordinary fees and expenses associated with certain legal matters. In August 2003, the Company reached a tentative settlement agreement related to an employment and wages claim. The Company currently expects this claim to be resolved around the end of its fiscal year 2003. The expected amount necessary to provide for the resolution of this matter has been accrued in the condensed consolidated financial statements of June 30, 2003. 9

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS The following discussion should be read in conjunction with the information in the unaudited condensed consolidated financial statements and notes thereto included herein and WESCO International Inc.'s Financial Statements and Management's Discussion and Analysis of Financial Condition and Results of Operations included in its 2002 Annual Report on Form 10-K. GENERAL WESCO is a full-line distributor of electrical supplies and equipment and is a provider of integrated supply procurement services. WESCO currently operates over 350 branch locations and five distribution centers in the United States, Canada, Mexico, Puerto Rico, Guam, the United Kingdom, Nigeria and Singapore. WESCO serves over 100,000 customers worldwide, offering over 1,000,000 products from over 24,000 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 89% of WESCO's net sales are generated from operations in the U.S., 9% from Canada and the remainder from other countries. CRITICAL ACCOUNTING POLICIES AND ESTIMATES During six-month period ended 2003, there were no significant changes to WESCO's Critical Accounting Policies and Estimates referenced in the 2002 Annual Report on Form 10-K. RESULTS OF OPERATIONS Second Quarter of 2003 versus Second Quarter of 2002 The following table sets forth the percentage relationship to net sales of certain items in WESCO's condensed consolidated statements of operations for the periods presented: THREE MONTHS ENDED JUNE 30 --------------------------- 2003 2002 --------------------------- Net sales 100.0% 100.0% Gross profit 18.4 17.6 Selling, general and administrative expenses 15.5 14.6 Depreciation and amortization 0.6 0.5 --- --- Income from operations 2.3 2.5 Interest expense 1.2 1.3 Other expense 0.2 0.2 --- --- Income before income taxes 0.9 1.0 Provision for income taxes 0.0 0.3 --- --- Net income 0.9% 0.7% ==== ==== Net sales in the second quarter of 2003 total $820.2 million versus $848.4 million in the comparable 2002 quarter, a 3.3% decline. The decline in net sales was primarily attributable to weaker demand resulting from depressed economic activity in the industrial production and commercial construction markets. Gross profit for the second quarter of 2003 of $150.9 million was up slightly as compared to 2002's second quarter, as the gross margin percentage improved to 18.4% versus 17.6% last year. The improvement in the gross margin percentage was primarily due to improvements in billing margins, which increased 70 basis points over last year's comparable quarter. Selling, general and administrative ("SG&A") expenses in the second quarter of 2003 totaled $126.8 million versus $123.4 million in last year's comparable quarter. The current quarter's total includes $5.7 million of expenses associated with discretionary retirement plan contributions and out of the ordinary fees and expenses associated with certain legal matters. In August 2003, the Company reached a tentative settlement agreement related to an employment and wages claim. The Company accrued the expected amount necessary to provide for the resolution of this matter during the fiscal quarter ended June 30, 2003. Partially offsetting these amounts were decreases in other SG&A expenses, the most significant of which was transportation costs. Shipping and handling expense included in SG&A was $9.0 million in the second quarter of 2003, compared with $9.8 million in last 16

year's second quarter. As a percentage of net sales, SG&A expenses increased to 15.5%, compared with 14.6% in the prior year quarter, reflecting the higher amount of SG&A expenses in the current quarter combined with the negative leverage of lower sales volume. Depreciation and amortization was $5.1 million in the second quarter of 2003 versus $4.4 million in last year's second quarter. Interest expense totaled $10.5 million for the second quarter of 2003 versus $11.1 million in last year's comparable quarter, a decrease of 5.4%. The decline was due to a lower amount of indebtedness outstanding during the current quarter as compared to the second quarter of 2002. Other expense totaled $1.3 million in 2003 second quarter, down from $1.7 million in the comparable 2002 second quarter, principally reflecting lower costs and outstanding balances associated with the accounts receivable securitization program. Income tax benefit totaled $0.2 million in the second quarter of 2003 and the effective tax rate was a 2.6% benefit. Income tax expense totaled $3.2 million in the second quarter of 2002 and the effective tax rate was 36.7%. The effective tax rate in the second quarter of 2003 differs from the statutory rate primarily as a result of the recognition of a $2.4 million benefit associated with the favorable resolution of certain prior year tax contingencies. Last year's effective tax rate differed from the statutory rate primarily due to state taxes and non-deductible expenses. For the second quarter of 2003, net income totaled $7.4 million, or $0.16 per diluted share, compared with $5.6 million, or $0.12 per diluted share, in the second quarter of 2002. The improvements in net income and earnings per share were primarily attributable to lower financing costs and the lower effective tax rate in the current quarter. Six Months Ended June 30, 2003 versus Six Months Ended June 30, 2002 The following table sets forth the percentage relationship to net sales of certain items in WESCO's condensed consolidated statements of operations for the periods presented: SIX MONTHS ENDED JUNE 30 2003 2002 -------------------------------------------------------------------- Net sales 100.0% 100.0% Gross profit 18.4 17.8 Selling, general and administrative expenses 15.4 14.8 Depreciation and amortization 0.7 0.6 ---------------------- Income from operations 2.3 2.4 Interest expense 1.3 1.3 Loss on debt extinguishment - - Other expense 0.1 0.2 ---------------------- Income before income taxes 0.9 0.9 Provision for income taxes 0.1 0.3 ---------------------- Net income 0.8% 0.6% -------------------------------------------------------------------- Net sales in the six months ended June 30, 2003 total $1,611.0 million versus $1,657.4 million in the comparable 2002 period, a 2.8% decline. The decline in net sales was primarily attributable to weaker demand resulting from depressed economic activity in the industrial production and commercial construction markets. Gross profit for the six months ended June 30, 2003 of $296.3 million was up slightly versus last year's comparable period, as the gross margin percentage improved to 18.4% versus 17.8% last year. The improvement in the gross margin percentage was primarily due to improvements in billing margins, which increased 50 basis points over last year's comparable period. SG&A expenses during the six months ended June 30, 2003 totaled $248.5 million versus $245.5 million in last year's comparable period. The current year's total includes $8.1 million of expenses associated with discretionary retirement plan contributions and out of the ordinary fees and expenses associated with certain legal matters. In August 2003, the Company reached a tentative settlement agreement related to an employment and wages claim. The Company accrued the expected amount necessary to provide for the resolution of this matter during the six months ended June 30, 2003. Partially offsetting these amounts were decreases in other SG&A expenses the most 17

significant of which was transportation costs. Shipping and handling expense included in SG&A was $17.8 million during the 2003 six-month period versus $18.9 million in last year's comparable period. As a percentage of net sales, SG&A expenses increased to 15.4% compared with 14.8% in the last year's six-month period reflecting the higher amount of SG&A expenses in the period, combined with the negative leverage of lower sales volume. Depreciation and amortization was $10.3 million in the first six months of 2003 versus $9.6 million in last year's comparable period. Interest expense totaled $20.9 million for the six months ended June 30, 2003 versus $22.1 million in last year's comparable period, a decrease of 5.0%. The decline was due to a lower amount of indebtedness outstanding during the current period. Other expense totaled $2.7 million in 2003, down from $3.1 million in the comparable 2002 period, principally reflecting costs associated with the accounts receivable securitization program. For the six months ended June 30, 2003, income tax expense totaled $1.7 million and the effective tax rate was 12.5%. Income tax expense totaled $4.4 million in last year's comparable period and the effective tax rate was 31.7%. The effective tax rate in the current-year period differs from the statutory rate primarily as a result of the recognition of a $2.4 million benefit associated with the favorable resolution of certain prior year tax contingencies, combined with the recognition of a $0.6 million benefit associated with the utilization of a net operating loss. Last year's effective tax rate differed from the statutory rate primarily due to deferred taxes being remeasured during the period reflecting the cumulative impact of a change in the expected tax rate that will be applicable when the deferred tax items reverse. The change in estimate was primarily due to state tax reduction initiatives. In addition, foreign tax credits contributed to the reduction in the effective rate during both 2003 and 2002. For the six months ended June 30, 2003, net income totaled $12.2 million, or $0.26 per diluted share, versus $9.4 million, or $0.20 per diluted share, in last year's comparable period. The improvements in net income and earnings per share were primarily attributable to lower financing costs and the lower effective tax rate in the current quarter. LIQUIDITY AND CAPITAL RESOURCES Total assets were $1.1 billion and $1.0 billion at June 30, 2003 and December 31, 2002, respectively. The increase in total assets was principally attributable to a $90.2 million increase in trade accounts receivable, with $68 million of the increase being attributable to reduced utilization of the Company's accounts receivable securitization program. During the first six months of 2003, total liabilities increased $63.4 million to $909.2 million. The increase was the result of a $28.1 million increase in trade accounts payable, coupled with a $32.0 million increase in long-term debt. The increase in long-term debt was a result of the closing of a $51.0 million real estate financing during the first six months of 2003. Borrowings under this financing total $13.3 million as of December 31, 2002. During the 2003 first quarter, stockholders' equity increased $19.5 million to $188.8 million as of June 30, 2003 as a result of $12.2 million in net income, coupled with a $7.2 million favorable adjustment related to foreign currency translation. WESCO's liquidity needs arise from seasonal working capital requirements, capital expenditures, acquisitions and debt service obligations. In addition, certain of our acquisition agreements contain earn-out provisions based principally on future earnings targets. The most significant of these agreements relates to the acquisition of Bruckner Supply Company, which provides for an earn-out potential of $80 million during either one of the next two years if certain earnings targets are achieved. The amount of earn-out proceeds earned that is payable in any single year is capped under this agreement at $30 million per year. Certain other acquisitions also contain contingent consideration provisions, only one of which could require a significant payment. Management estimates this payment could range from $0 to $20 million and would be made in 2008. To meet its funding requirements, WESCO uses a mix of internally generated cash flow, its revolving credit facility, its Receivables Facility and equity transactions. WESCO finances its operating and investing needs, as follows: Accounts Receivable Securitization Program WESCO maintains a Receivables Facility with a group of financial institutions. Under the Receivables Facility, WESCO sells, on a continuous basis, to WESCO Receivables Corporation, a wholly-owned SPC, an undivided interest in all domestic accounts receivable. The SPC sells without recourse to a third-party conduit, all the eligible receivables while maintaining a subordinated interest, in the form of overcollateralization, in a portion of the receivables. WESCO 18

has agreed to continue servicing the sold receivables for the financial institution at market rates; accordingly, no servicing asset or liability has been recorded. The effective cost of this financing facility is currently approximately 2.0% per annum. As of June 30, 2003, $225 million in funding was outstanding under the Receivables Facility and excess availability was $17 million. On June 28, 2003, this facility was extended until August 31, 2003 with a total purchase commitment of up to $242 million. The Company expects to enter into a similar facility with a purchase commitment of up to $350 million before the expiration date of the current facility. This new structure is expected to include the addition of a three-year commitment of up to $150 million that will minimize the amount that is subject to an annual renewal. Mortgage Financing Facility During the six months ended June 30, 2003, WESCO finalized a $51 million mortgage financing facility. Borrowings under the mortgage financing are subject to a 22-year amortization schedule with a balloon payment due at the end of the 10-year term. In 2003, scheduled principal payments total approximately $0.8 million. Interest cost for the mortgage facility is fixed at 6.5% per annum. Proceeds from the borrowings were used to reduce outstanding borrowings under the 2002 Revolving Credit Facility. 2002 Revolving Credit Facility In March 2002, WESCO Distribution, Inc. entered into a $290 million revolving credit agreement that is collateralized by substantially all inventory owned by WESCO and also by the accounts receivable of WESCO Canada. Availability under the agreement, which matures in 2007, is limited to the amount of eligible inventory and Canadian receivables applied against certain advance rates. Proceeds from this agreement were used to retire WESCO Distribution Inc.'s existing revolving credit facility. Interest on this facility is at LIBOR plus a margin that will range between 2.0% to 2.75% depending upon the amount of excess availability under the facility. As long as the average daily excess availability for both the preceding and projected succeeding 90 day period is greater than $50 million, then WESCO would be permitted to make acquisitions and repurchase outstanding public stock and bonds. The above permitted transactions would also be allowed if such excess availability is between $25 million and $50 million and WESCO's fixed charge coverage ratio, as defined by the agreement, is at least 1.25 to 1.0 after taking into consideration the permitted transaction. Additionally, if excess availability under the agreement is less than $50 million, then WESCO must maintain a fixed charge coverage ratio of 1.1 to 1.0. At June 30, 2003, the interest rate was 3.7%. This facility also has various restrictive covenants including financial ratios. WESCO was in compliance with all such covenants as of June 30, 2003. As of June 30, 2003, WESCO had $7 million in borrowings outstanding under this facility and, after deducting $12 million in outstanding letters of credit, $161 million in availability. Senior Notes As of June 30, 2003 WESCO had $397 million in aggregate principal amount of senior subordinated notes due 2008. The notes were issued with an average issue price of 98%. The net proceeds received by the Company from the notes were approximately $376 million. Interest on these notes accrues at a rate of 9.125% per annum and is payable semi-annually on December 1 and June 1. Interest Rate Swap Agreements During September and October of 2001, WESCO entered into four separate fixed-to-floating interest rate swap agreements, each with a notional amount of $25 million. These agreements had six-year terms expiring concurrently with the 9.125% senior subordinated notes with the intent of converting $100 million of the senior subordinated notes from a fixed-to-floating rate facility. Pursuant to these agreements, WESCO received fixed interest payments at the rate of 9.125% and was paid interest at three-month LIBOR plus a premium. The LIBOR rates in the agreements were reset quarterly. During the six months ended June 30, 2003, these agreements were settled and as a result the Company received $4.6 million. The gain resulting from the settlement of these agreements has been deferred and is being amortized as a reduction of interest expense over the remaining life of the senior subordinated notes. Management believes that cash generated from operations, together with amounts available under its credit facilities, will be sufficient to meet WESCO's working capital, capital expenditures and other cash requirements for the foreseeable future. There can be no assurance, however, that this will be or will continue to be the case. 19

Cash Flow Operating Activities. Cash used by operating activities during the six months ended June 30, 2003 totaled $18.3 million as compared to $69.1 million in the prior year. Included in the 2003 use of cash was a $68.0 million use associated with changes in WESCO's Receivables Facility compared to $55.0 million in the prior year. Cash provided by other operating activities totaled $49.7 million during the first six months of 2003 compared to cash used by other operating activities of $14.1 million in the previous year. In 2003, cash generated by net income of $12.2 million plus non-cash items of $10.4 million and $37.1 million from changes in inventory, prepaid expenses and other current assets, accounts payable and other current and non-current liabilities totaling were partially offset by cash used to fund increases in accounts receivable and other items totaling $10.0 million. In 2002, cash utilized to reduce accounts payable of $92.1 million was partially offset by cash generated by reductions in accounts receivable and inventory of $58.8 million. Investing Activities. Net cash used for investing activities was $4.8 million during the first six months of 2003, principally due to capital expenditures of $3.4 million. Acquisition payments totaling $2.5 million were partially offset by proceeds received from the sale of property and buildings totaling $1.2 million. In 2002, cash used by investing activities totaled $13.4 million and included capital expenditures of $3.4 million and acquisition payments of $10.7 million, partially offset by proceeds from the sale of property of $0.8 million. Financing Activities. Net cash provided by financing activities during the first six months of 2003 totaled $33.2 million. The cash flow provided was a result primarily of completing the real estate financing during the period, which provided $38 million in funding. In addition, the Company received $4.6 million in proceeds from the settlement of its interest rate swap agreements. Partially offsetting these sources of cash was $8.0 million reduction in net debt repayments. In 2002, cash provided by financing activities totaled $31.4 million reflecting net borrowings of $33.9 million. Contractual Cash Obligations and Other Commercial Commitments As disclosed above, WESCO finalized a $51 million mortgage financing facility during the first quarter. As a result of finalizing this agreement, the total debt owed on the mortgage facility increased $38 million to $51 million as compared to $13 million referenced in WESCO's 2002 Form 10-K. In 2003, scheduled principal payments total approximately $0.8 million. 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 the Company during the periods presented. However, inflation in the future could affect the Company's operating costs. Price changes from suppliers have historically been consistent with inflation and have not had a material impact on the Company's results of operations. Seasonality The Company'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 a reduced level of activity during the holiday season. As a result, the Company reports sales and earnings in the first quarter that are generally lower than that of the remaining quarters. Impact of Recently Issued Accounting Standards In December 2002, the FASB issued SFAS No. 148, "Accounting for Stock-Based Compensation -- Transition and Disclosure -- an amendment of SFAS No. 123." SFAS No. 148 was issued to provide alternative methods of transition for a voluntary change to the fair-value-based method of accounting for stock-based employee compensation. In addition, this statement amends the disclosure requirements of SFAS No. 123 to require prominent disclosures in both annual and interim financial statements about the method of accounting for stock-based employee compensation and the effect of the method used on reported results. The amendments to SFAS No. 123 in paragraphs 2(a)-2(e) of this statement shall be effective for financial statements for fiscal years ending after December 15, 2002. Currently, WESCO is evaluating the impact of adopting the fair-value-based method of accounting for stock-based compensation under SFAS No. 148. 20

Effective June 30, 2003, WESCO adopted SFAS No. 149, "Amendment of Statement 133 on Derivative Instruments and Hedging Activities." This statement amends and clarifies financial accounting and reporting for derivatives and for hedging activities under SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities." This standard had no impact on WESCO's financial statements. In May 2003, the FASB issued SFAS No. 150, "Accounting for Certain Instruments with Characteristics of Both Liabilities and Equity." This standard requires that certain financial instruments embodying an obligation to transfer assets or to issue equity securities be classified as liabilities. It is effective for financial instruments entered into or modified after May 31, 2003, and otherwise is effective July 1, 2003. This standard had no impact on WESCO's financial statements. In November 2002, the FASB issued Interpretation No. 45, "Guarantor's Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others," which elaborates on the disclosures to be made by a guarantor in its interim and annual financial statements about its obligations under certain guarantees that it has issued. It also clarifies that a guarantor is required to recognize, at the inception of a guarantee, a liability for the fair value of the obligation undertaken in issuing the guarantee. This interpretation does not prescribe a specific approach for subsequently measuring the guarantor's recognized liability over the term of the related guarantee. This interpretation also incorporates, without change, the guidance in FASB Interpretation No. 34, "Disclosure of Indirect Guarantees of Indebtedness of Others," which is being superseded. The initial recognition and initial measurement provisions of this interpretation are applicable on a prospective basis to guarantees issued or modified beginning January 1, 2003. The adoption of this statement did not have a material impact on WESCO's financial statements. In January 2003, the FASB issued Interpretation No. 46, "Consolidation of Variable Interest Entities." This interpretation requires unconsolidated variable interest entities to be consolidated by their primary beneficiaries if the entities do not effectively disperse the risk and rewards of ownership among their owners and other parties involved. The provisions of this interpretation are effective immediately to all variable interest entities created after January 1, 2003 and variable interest entities in which an enterprise obtains an interest in after that date. For variable interest entities created before this date, the provisions are effective July 31, 2003. WESCO does not believe the adoption of this interpretation will have a material impact on its consolidated financial statements. FORWARD-LOOKING STATEMENTS From time to time in this report and in other written reports and oral statements, references are made to expectations regarding the future performance of WESCO. When used in this context, the words "anticipates," "plans," "believes," "estimates," "intends," "expects," "projects" and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain such words. Such statements including, but not limited to, WESCO's statements regarding its 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 WESCO's control. WESCO's actual results could differ materially from those expressed in any forward-looking statement made by or on behalf of WESCO. 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, an increase in competition, the amount of outstanding indebtedness, the availability of appropriate acquisition opportunities, availability of key products, functionality of information systems, international operating environments and other risks that are described in WESCO's Annual Report on Form 10-K for the year ended December 31, 2002 which are incorporated by reference herein. WESCO has undertaken no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKS Except as discussed below, there have not been any material changes to WESCO's exposures to market risk during the six months ended June 30, 2003 that would require an update to the disclosures provided in WESCO's Form 10-K for the year-ended December 31, 2002. As previously disclosed, the Company's interest rate swap agreements were settled during the six months ended June 30, 2003. The Company received $4.6 million related to the contracts. 21

ITEM 4. CONTROLS AND PROCEDURES (a) Evaluation of Disclosure Controls and Procedures WESCO's Chief Executive Officer ("CEO") and Chief Financial Officer ("CFO"), have evaluated the Company's disclosure controls and procedures as of the end of the period covered by this report and they have concluded that these controls and procedures are effective. (b) Changes in Internal Control Over Financial Reporting There have been no significant changes in internal control over financial reporting that occurred during the quarter ended June 30, 2003, that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting. 22

PART II - OTHER INFORMATION ITEM 1. LEGAL PROCEEDINGS From time to time, a number of lawsuits, claims and proceedings have been or may be asserted against us relating to the conduct of our business, including routine litigation relating to commercial and employment matters. While the outcome of litigation cannot be predicted with certainty, and some of these lawsuits, claims or proceedings may be determined adversely to the Company, the Company does not believe, based on information presently available to it, that the outcome of any of such pending matters is likely to have a material adverse effect on the Company. In August 2003, the Company reached a tentative settlement agreement related to an employment and wages claim. The Company currently expects this claim to be resolved around the end of its fiscal year 2003. The expected amount necessary to provide for the resolution of this matter has been accrued in the condensed consolidated financial statements as of June 30, 2003. ITEM 4.
