         Pittsburgh, PA, October 22, 2003 - WESCO International, Inc.
[NYSE:WCC], a leading provider of electrical MRO products, construction
materials, and advanced integrated supply procurement outsourcing services,
today announced its 2003 third quarter financial results.

         Net sales for the third quarter of 2003 were $825.6 million versus
$852.9 million in 2002, a decline of 3.2%. Gross margins for the quarter
improved to 18.6% versus 17.2% for the comparable quarter in 2002. Last year's
gross margin results included a $5.2 million charge to establish inventory
reserves for specialty inventory related to customers in the telecommunication
industry and the Middle East. Operating income for the current quarter totaled
$23.9 million versus $18.3 million in last year's comparable quarter, an
improvement of 30.6%. Depreciation and amortization included in operating income
was $5.1 million in 2003's third quarter versus $5.0 million in 2002. Net income
in 2003's third quarter was $8.4 million versus $9.0 million in the comparable
2002 quarter. Included in 2003's net results is a $0.5 million non-cash charge
($0.01 per share) related to a Company-initiated amendment reducing the size of
the Company's revolving credit facility. Last year's net results included a $5.3
million net benefit ($0.11 per share) from the reversal of income tax
contingency accruals. Earnings per share in the current quarter were $0.18 per
share versus $0.19 per share in 2002.

         Net sales for the nine months ended September 30, 2003 were $2,436.6
million versus $2,510.3 million in last year's comparable period, a 2.9%
decline. Gross margins in the current nine-month period were 18.5% versus 17.6%
last year and operating income totaled $61.3 million versus $58.4 million last
year. Depreciation and amortization included in operating income was $15.4
million versus $14.6 million last year. Net income for the 2003 year-to-date
period was $20.6 million versus $18.4 million last year, while diluted earnings
per share were $0.44 per share in 2003 versus $0.39 per share in 2002.

         During the third quarter, the Company adopted the measurement
provisions of SFAS #123, "Accounting for Stock-Based Compensation" on a
prospective basis in accordance with SFAS #148, "Accounting for Stock-Based
Compensation - Transition and Disclosure - an amendment of SFAS #123".
Consequently, the quarter results include $0.2 million net charge to recognize a
pro rata portion of the fair value of stock options issued to employees and
directors of the Company during the third quarter ended September 30, 2003.








         Stephen A. Van Oss, Vice President and Chief Financial Officer, stated,
"Our focus on margin expansion and quality of business initiatives are
delivering improved operating results. Operating income for the quarter at $23.9
million was the highest since the third quarter of 2001 on lower sales. Our cash
flow generation continues to be strong. Cash flow generated in the quarter was
utilized to reduce total indebtedness (including our accounts receivable
securitization program), net of cash, by $34.8 million to $607.3 million as of
September 30, 2003. For the year, total indebtedness, net of cash, has been
reduced by $81.1 million."

         Mr. Van Oss, continued, "During the last two years, the Company has
engaged in a series of capital market transactions which have established a
balanced capital structure for WESCO that provides low-cost financing, staggered
extended maturities, operating flexibility, an appropriate blend of fixed and
variable rate debt and significant liquidity. Our latest transaction, completed
early in this quarter, was to revise and improve our annual Accounts Receivable
Securitization facility. The new $300 million facility offers very competitive
low-cost financing and includes a unique feature whereby $135 million of the
total facility is provided under a three-year term with the remaining $165
million under a one-year term. Our available borrowing capacity was
approximately $185 million as of September 30, 2003."

         WESCO's Chairman and Chief Executive Officer, Roy W. Haley, commented,
"WESCO, through its 350 branches and 1,100 outside salespeople, is closely
aligned to major industrial and commercial construction market segments
throughout North America, and we are monitoring economic market conditions
closely. We are pleased to see signs of market stabilization, including certain
areas of growth. The Company is committed to its business strategy and is
optimistic about its prospects, despite the challenges presented by the
prolonged economic downturn. We continue to make steady progress in our
performance including improvements in margins, cash generation and overall
profitability. Further performance gains are expected to be realized based on
the success of our LEAN Enterprise initiatives focused on selling performance,
customer service capabilities, and cost efficiencies."

Note: Trade accounts receivable and long-term debt have each been reduced by
$205 million and $293 million as of September 30, 2003 and December 31, 2002,
respectively, in accordance with WESCO's accounting for its Accounts Receivable
Securitization facility. In addition, the carrying value of long-term debt
increased by $2.1 million during the nine months ended September 30, 2003 as a
result of non-cash amortization of discounts associated with the Company's
Senior Notes.

Note: Total indebtedness (including A/R Securitization Program), net of cash is
provided by the Company as an additional measure of the Company's indebtness.
Generally accepted accounting principles require that this financing facility be
presented off-balance sheet. As management internally evaluates the A/R
Securitization facility as an additional form of indebtedness, management
believes it is helpful to provide the readers of its financial statements an
evaluation of its total indebtedness from all sources of financing. Cash and
cash equivalents are deducted from this total to determine total indebtedness
(including A/R Securitization Program), net of cash. This amount represents the
Company's net obligation due under all of its financing facilities.
