Fiscal 2014 First Quarter Results

Revenue for the first fiscal quarter was $224.7 million, an increase of 6.4% compared to $211.2 million in the prior year period.  The increase in the North America segment was 4.7% over the prior year period.  Wesco again demonstrated strong international growth during the quarter with revenues in the Rest of World segment increasing by 19.6% compared to the prior year period.  In the first quarter, Ad Hoc, JIT and LTA sales as a percentage of net sales represented 39%, 31% and 30%, respectively, compared to 40%, 26% and 34%, respectively, for the same period last year.

Net income for the first quarter was $24.4 million, resulting in Diluted EPS of $0.25 as compared to $18.4 million or $0.19 per share in the prior year period.  Adjusted Net Income was $25.9 million resulting in Adjusted EPS of $0.27 in the first quarter of 2014 as compared to $24.1 million or $0.25 per share in the prior year period.  Results for the first quarter of 2014 were impacted by one fewer business day compared to last year, as well as prolonged holiday shutdowns and vacations at a number of our top customers.

Wesco Aircraft’s Chairman, President and Chief Executive Officer, Randy Snyder said, “Our first quarter results were solid despite the timing of the holidays.    We are experiencing high levels of activity in orders, additions to our current contracts, and contract renewals with existing customers.  These results give us confidence in our full year guidance for sales and earnings growth.  In addition, our recently announced acquisition of Haas adds to our optimism for the rest of the year and beyond.  None of this would be achievable without our strong customer relationships, the support of our suppliers and the dedicated efforts of the best employees in the business.”

Wesco Aircraft 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.
