Fiscal 2012 Second Quarter Results

Revenue for the second fiscal quarter was $182.1 million, an increase of 3.5% compared to $176.0 million in the prior year period.  For the first six months of the fiscal year, total revenue was $374.7 million, up 7.2% compared to the prior year period. During the second quarter, Wesco’s Rest of World segment continued to be a significant driver of growth, with revenues increasing by 22.8%.  In the second quarter, Ad hoc, JIT and LTA sales as a percentage of net sales represented 40%, 23% and 37%, respectively, compared to 38%, 32% and 30%, respectively, for the same period last year.

Net income for the second quarter of fiscal 2012 was $19.7 million, resulting in Diluted Earnings Per Share of $0.21.  This compared to $21.9 million, or $0.24 per share in the prior year period. Adjusted EBITDA for the second quarter was $38.3 million as compared to $44.9 million in the second quarter of 2011.  The decrease was driven by higher selling, general and administrative expenses, including significant costs associated with operating as a public company, additional costs to support new contracts that have not fully ramped up, as well as a $2.2 million favorable recovery of bad debt expense in the prior year period. Adjusted Net Income was $20.8 million, resulting in Adjusted Diluted Earnings Per Share of $0.22, compared to $23.1 million, or $0.25 per share in the prior year period.

Randy Snyder, Wesco’s Chairman, President, and Chief Executive Officer said, “During the second quarter we reported modest year-on-year revenue growth, and continued to see the benefits of our long-term investment in international markets, with Rest of World revenue increasing over 20% in the quarter. 2012 continues to be an important year of transition for Wesco as we strengthen our public company functions and begin to ramp-

up several significant new contracts. We expect that, over time, these contracts will more than offset the revenues relating to the two programs completed in Charleston, SC last year. Excluding these two programs Wesco sales would have grown 14.3% in the first half of 2012.”

Financial Outlook

“As we have made progress in the implementation of several new contracts, we have found that the level of existing inventory at some customers was higher than expected. Due to this fact, it will take longer to reduce the inventory on-hand and ramp-up sales of products provided by Wesco. Because of this, we believe it is appropriate to revise our financial outlook for the full year based on what we are seeing today,” continued Snyder.

Wesco is revising its full year fiscal 2012 guidance for revenues of between $740-760 million, representing a growth rate of approximately 4-7% over 2011 results, or 12-15% excluding the Charleston programs.  Diluted EPS and Adjusted Diluted EPS are expected to be in the range of $0.88 to $0.93, and $0.92 to $0.97, respectively.  These EPS estimates are based on estimated 2012 fiscal year averages of 92.4 million basic shares and 95.6 million diluted shares.

Non-GAAP Financial Information

‘‘Adjusted Net Income’’ represents Net Income before: (i) amortization of intangible assets, (ii) amortization or write-off of deferred financing costs and original issue discount, or OID, (iii) Carlyle Acquisition related non-cash stock-based compensation expense, (iv) unusual or non-recurring items and (v) the tax effect of items (i) through (iv) above calculated using an assumed effective tax rate.

“Adjusted Basic EPS” represents Basic EPS calculated using Adjusted Net Income as opposed to Net Income.

Wesco utilizes and discusses Adjusted Net Income, Adjusted Basic EPS, Adjusted Diluted EPS and Adjusted EBITDA, which are non-GAAP measures our management uses to evaluate our business, because we believe they assist investors and analysts in comparing our performance across reporting periods on a consistent basis by excluding items that we do not believe are indicative of our core operating performance. We believe these metrics are used in the financial community, and we present these metrics to enhance investors’ understanding of our operating performance. You should not consider Adjusted EBITDA and Adjusted Net Income as an alternative to Net Income, determined in accordance with GAAP, as an indicator of operating performance. Adjusted Net Income, Adjusted Basic EPS, Adjusted Diluted EPS and Adjusted EBITDA are not measurements of financial performance under GAAP, and these metrics may not be comparable to similarly titled measures of other companies. See below for a reconciliation of Adjusted Net Income, Adjusted Basic EPS, Adjusted Diluted EPS and Adjusted EBITDA to the most directly comparable financial measures calculated and presented in accordance with GAAP.
