Diluted earnings per share in the current quarter were $0.93 per share, compared with $0.86 per share in the first quarter of 2006. Included in the current quarter were nonrecurring items totaling a net charge of $0.06 per share. The nonrecurring items were comprised of an after-tax charge of $4.9 million, or $0.09 per share, relating to the settlement of litigation and an after-tax gain of $1.6 million, or $0.03 per share, resulting from a change in the accounting treatment of WESCO's accounts receivable securitization facility. Net income in the first quarter was $48.2 million in 2007 versus $44.5 million in the comparable 2006 quarter.

Consolidated net sales for the first quarter 2007 were $1,450.6 million compared with $1,265.5 million in the first quarter of 2006, an increase of 15%. Sales in the current quarter from Communications Supply Corporation ("CSC"), acquired in the fourth quarter of 2006, were approximately $160 million. Gross margin for the quarter improved to 20.6% versus 20.0% reported for the comparable quarter last year. Operating income for the quarter totaled $82.5 million, an increase of 7% over the $76.9 million earned in the first quarter of 2006. Adjusting for the one-time litigation cost, operating income increased by 17%. Depreciation and amortization included in operating income was $8.9 million in the first quarter of 2007 compared to $6.3 million in the first quarter of 2006.

Free cash flow was $73 million. During the quarter WESCO purchased over three million shares of its stock for approximately $198 million under a previously announced $400 million share repurchase program. Since 2004, expenditures of over $1 billion on acquisitions and share repurchases have been made. At March 31, 2007, financial leverage, defined as total debt divided by EBITDA, was 3.1 times and compares to the year-end 2004 level of 3.7 times.

Stephen A. Van Oss, Senior Vice President and Chief Financial and Administrative Officer, stated, "During the quarter, we achieved a record level of sales and first quarter records for operating profit and net income. Excellent free cash flow and our flexible capital structure allowed us to get a good start on our $400 million share repurchase program, which we expect to complete over the next 12 months."

Mr. Van Oss continued, "Although overall financial performance and profitability ratios, adjusted for one-time litigation expenses, were in line with our longer term expectations, organic sales growth and incremental profitability were below internal targets as we responded to a transitioning economy and lower commodity prices. Core electrical sales rose 2%, while sales at our most recent acquisition, CSC, added 13% to consolidated sales revenue. Gross margins were maintained despite margin compression in a few commodity based categories. Our operating cost expense ratio was above target due to the lower than expected sales for the quarter, but supports our current outlook for the remainder of 2007."

"With regard to our acquisition program," added Van Oss, "CSC is performing slightly better than our initial projections, and operational integration activities are on track. We remain committed to full year 2007 earnings accretion of $0.35-0.40 per share. We are particularly pleased with the early progress being made in joint sales and service activities and the identification of numerous growth opportunities."

Roy W. Haley, Chairman and Chief Executive Officer, commented, "It has been and continues to be our view that the U.S. economy is quite resilient. Even though there has been a slowdown in activity, market conditions, in the aggregate, remain favorable for our business. As reported, we have encountered unanticipated sales weakness in early 2007, as capital expenditures and large construction project spending have developed more slowly than expected. Nevertheless, we know that there is a lot of future business being developed. A growing backlog of orders for future business and positive feedback from customers and our sales personnel support our expectations that full year results for organic sales growth will be in the range of 6-8%. This level of organic growth, successful development of acquisition synergies, and ongoing productivity enhancement initiatives are expected to help us achieve new year over year records for both sales and profitability."

Note: As previously noted, WESCO amended and restated its accounts receivable securitization facility as of December 29, 2006. Historically, accounts receivable sold under the facility were removed from the consolidated balance sheet and accounted for as an off-balance sheet arrangement. Effective with the amendment, sales of accounts receivable pursuant to the facility no longer qualify for "sale treatment" under GAAP. Therefore, the consolidated balance sheets as of March 31, 2007 and December 31, 2006 reflect $440 million and $390.5 million of additional accounts receivable and related borrowings.
