         Pittsburgh, PA, July 23, 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 second quarter financial results.

         Net sales for the second quarter of 2003 were $820.2 million versus
$848.4 million in 2002, a decline of 3.3%. Gross margins for the quarter
improved to 18.4% versus 17.6% for the comparable 2002 quarter. Operating income
for the current quarter totaled $19.0 million versus $21.6 million in last
year's comparable quarter. Depreciation and amortization included in operating
income was $5.1 million for 2003 versus $4.4 million in 2002. Net income in
2003's second quarter was $7.4 million versus $5.6 million in the comparable
2002 quarter. Earnings per share were $0.16 per share versus $0.12 per share in
2002.

         On a year-to-date basis, net sales for the six months ended June 30,
2003 were $1,611.0 million versus $1,657.4 million in last year's comparable
period, a 2.8% decline. Gross margins in the current six-month period were 18.4%
versus 17.8% last year and operating income totaled $37.5 million versus $40.0
million last year. Depreciation and amortization included in operating income
was $10.3 million versus $9.6 million last year. Net income for the 2003
year-to-date period was $12.2 million versus $9.4 million last year, while
diluted earnings per share were $0.26 per share in 2003 versus $0.20 per share
in 2002.

         Stephen A. Van Oss, Vice President and Chief Financial Officer, stated,
"We are pleased with the continuing improvements we have achieved in gross
margins, particularly given weak product demand from our end markets. Higher
employee benefit costs and out of the ordinary fees and expenses associated with
certain legal matters resulted in a 2.8% increase in selling, general and
administrative expenses over last year's comparable quarter. We expect to
achieve further improvements in our capital structure and in the quality of our
operations in the coming quarters. During the quarter, our free cash flow was
utilized to reduce total indebtedness (including our accounts receivable
securitization program), net of cash, by $26.9 million to $642.1 million as of
June 30, 2003. For the first six months of 2003, total indebtedness, net of
cash, was reduced by $46.3 million. The favorable resolution of certain prior
year tax contingencies resulted in a $2.4 million, or $0.05 per share, tax
benefit, reducing our effective tax rate to a 2.6% benefit for the quarter. We
currently expect our effective tax rate to return to a normalized level for the
balance of 2003."





         Mr. Van Oss, continued, "We have an abundant supply of capital
available to operate in the current economic environment. As of June 30, 2003,
we had unutilized borrowing capacity of approximately $178 million. The Company
is working towards the successful completion of a revised and improved Accounts
Receivable Securitization financing in an amount of up to $350 million. The new
structure includes the addition of a three-year commitment of up to $150 million
that will minimize the commitment amount that is subject to an annual renewal.
This financing will conclude, for now, a series of capital market transactions
that the Company has undertaken over the past two years to improve its capital
structure and liquidity position."

         WESCO's Chairman and Chief Executive Officer, Roy W. Haley, commented,
"WESCO has held its position in a difficult market, and we are confident that we
are well positioned for growth and gains in operating results as economic
activity improves. While we are optimistic in the long-term outlook for the
markets we serve, we have yet to see consistent evidence of a reversal in the
prolonged economic downturn that has adversely affected our industrial and
contractor customer base. For the near term, our strategy will be to emphasize
sales development programs and to achieve higher standards of service and
productivity through implementation of LEAN Enterprise initiatives in branch and
headquarters operations. As a result of the focus being given to these programs
by a large number of WESCO employees, we expect continued improvement in
profitability and cash flow during the remainder of the year."

Note: Trade accounts receivable and long-term debt have each been reduced by

respectively, in accordance with WESCO's accounting for its accounts receivable
securitization facility. In addition, the carrying value of long-term debt
decreased a net $2.1 million during the six months ended June 30, 2003 as a
result of the decrease in fair value of the Company's interest rate derivative
instruments and 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 additional measure of the Company's leverage.
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.
