Fiscal 2014 Second Quarter Results

Revenue for the second fiscal quarter was $327.4 million, an increase of 45% compared to $225.9 million in the prior year period.  The increase in external sales in the North America segment was 27%, which was mainly driven by growth across the Company’s customer base due to continued ramp-up of recently awarded contracts, scope expansion on existing contracts, new contracts and the acquisition of Haas.  Wesco Aircraft again demonstrated strong international growth during the quarter with external sales in the Rest of World segment increasing by 112% compared to the prior year period.  Overall, Wesco Aircraft organic sales increased approximately 21% compared to the prior year with the remaining approximately 24% contributed from Haas.  In the second quarter, Ad Hoc and Contract (which includes Just-In-Time contracts and Long Term Agreements) sales as a percentage of net sales represented 30% and 70%, respectively, compared to 41% and 59%, respectively, for the same period last year.  The movement is attributed to Haas having approximately 95% of their revenue under Contract.

Net Income for the second quarter was $24.3 million, resulting in Diluted EPS of $0.25. This compares to Net Income of $29.4 million or $0.31 in Diluted EPS in the prior year period.  Adjusted Net Income was $32.0 million and Adjusted Diluted EPS was $0.33 in the second quarter of 2014 as compared to $31.2 million or $0.33 per share in the prior year period.  The performance of Diluted EPS and Adjusted Diluted EPS were primarily the result of higher sales and the Haas acquisition, offset by higher selling, general and administrative expenses during the quarter.  Adjusted EBITDA for the period was $54.4 million as compared to $51.6 million for the same period in 2013.

Wesco Aircraft’s Chairman, President and Chief Executive Officer, Randy Snyder said, “Our first half results for new contract signings and revenue growth were strong relative to last year and were in line with our expectations.  We continue to experience high levels of booking activity, scope additions to our existing contracts and contract signings with new customers.  The Haas integration has gotten off to a great start.  The active collaboration between the legacy Wesco Aircraft and Haas sales forces is excellent and we anticipate great results from our combined efforts.  Our expansion into the MRO market continues to make better then expected progress.  We now offer 24/7 global coverage for this growing business.  These activities add to our confidence for the rest of the year and fuels our optimism for the future.  Wesco Aircraft’s growing global capabilities, dedication to our customers and focused process improvements continue to benefit our industry, our business partners and our shareholders.”

First Six Months of Fiscal 2014

Revenue for the first six months of fiscal 2014 was $552.1 million, an increase of 26% compared to $437.0 million in the prior year period.  On a year-to-date basis, Ad Hoc and Contract sales as a percentage of net sales represented 34% and 66%, respectively, compared to 40% and 60%, respectively, for the first six months of fiscal 2013.

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.
