·      Fourth quarter and full year Adjusted EBITDA of $46.1 million and $179.0 million, respectively.

Fiscal 2011 4th Quarter Results

Revenue for the fourth fiscal quarter was $181.3 million, an increase of 4.2% compared to $174.0 million in the prior year period.  Wesco continued to experience strong international growth during the quarter with revenues in the Rest of World segment increasing by 32.4% compared to the prior year.  In the fourth quarter, Ad hoc, JIT and LTA sales as a percentage of net sales represented 40%, 25% and 35%, respectively, compared to 38%, 31% and 31%, respectively, for the same period last year.

Adjusted EBITDA for the fourth quarter was $46.1 million as compared to $44.7 million in the fourth quarter of 2010.  The increase was due primarily to the growth in sales and an increase in gross profit margins, partially offset by higher selling, general and administrative expenses including costs associated with the Company’s new equity incentive plan.  Net income for the fourth quarter of 2011 was $18.0 million, resulting in Diluted Earnings Per Share (EPS) of $0.19.  This compared to $20.0 million, or $0.22 per share in the prior year period. This decline in net income as compared to the prior year quarter was primarily driven by expenses related to our equity incentive plans, $2.4 million of fees and expenses related to Wesco’s initial public offering and a higher effective tax rate related to increases in foreign sales of US product.  Adjusted Net Income was $22.4 million, resulting in Adjusted Diluted Earnings Per Share of $0.24, compared to $22.0 million, or $0.24 per share in the prior year period.

Fiscal 2011 Full Year Results

Revenue for the year was $710.9 million, an increase of 8.4% compared to $656.0 million in 2010.  The increase was driven by strong growth in all segments, with 6.8% growth in North America and 25.2% in the Rest of World segment.  Ad hoc, JIT and LTA sales increased year over year and, as a percentage of net sales, represented 39%,

29% and 32%, respectively, compared to 37%, 31% and 32%, respectively, for the same period last year.

Adjusted EBITDA for the year was $179.0 million as compared to $166.5 million in 2010.  The increase was primarily driven by higher sales, partially offset by higher selling, general and administrative expenses, primarily comprised of increases in payroll related costs.  Net income for 2011 was $75.6 million, resulting in Diluted Earnings Per Share of $0.81.  This compares to $73.7 million, or $0.81 per share in fiscal 2010. During 2011, net income was negatively impacted by $4.9 million of expenses related to the initial public offering, as well as a loss on the extinguishment of debt in the amount of $7.1 million in conjunction with the April 2011 debt refinancing.  Adjusted Net Income for full year fiscal 2011 was $90.1 million, resulting in Adjusted Diluted Earnings Per Share of $0.97, compared to $81.3 million, or $0.89 per share in 2010.

The Company generated $81.2 million of free cash flow and paid down $64.2 million of long term debt during 2011.

Randy Snyder, Wesco’s Chairman, President, and Chief Executive Officer said, “We are very pleased with our fourth quarter and full year results.  We have remained focused on supporting our customers and executing on several new contracts, which has generated record revenues for Wesco.  Our ability to grow in a challenging economic environment highlights the effectiveness of our business model, the passion of our employees, and our commitment to deliver on the promises we make to our customers.  We are very excited about our opportunities in the coming year.”

Financial Outlook

Based on the strong performance during fiscal year 2011, Wesco expects full year revenues for fiscal 2012 of between $760 million and $785 million, representing a growth rate of 7% to 10% over 2011 results.  Diluted EPS and Adjusted Diluted EPS are expected to be in the range of $0.98 to $1.02, and $1.03 to $1.07, respectively.  These EPS estimates are based on estimated 2012 fiscal year averages of 92.6 million basic shares and 95.8 million diluted shares.
