Third Quarter and Year-to-Date Financial Results Summary

Net Revenue

The Company reported net revenue of $97.9 million for the quarter ended April 30, 2017, as compared to $96.5 million for the same period in the prior year, an increase of $1.5 million or 1.5%. Driving the increase were higher revenues in Asia and Europe, up 11.6% and 3.3%, respectively, partially offset by declines in the Americas and in the Company’s e-Business segment.

The Company reported net revenue of $336.8 million for the nine months ended April 30, 2017, as compared to $357.5 million for the same period the prior year, a decline of $20.7 million or 5.8%. Net revenue in Europe increased $7.8 million or 6.7%, and this was offset by declines in the Company’s other reportable segments, primarily as a result of lower revenues from two clients in the consumer electronics industry.

Gross Margin

Gross margin for the quarter ended April 30, 2017 was 8.7%, as compared to 2.3% for the same period in the prior year, an improvement of 650 basis points. The improvement in gross margin was driven primarily by a more efficient use of temporary labor, and an overall focus on improving supply chain operations and pricing discipline. Furthermore, gross margins improved in each of the Company’s reportable operating segments, demonstrating the impact of the turnaround initiatives implemented throughout the course of the year.

Gross margin for the nine months ended April 30, 2017 was 8.6%, as compared to 5.1% for the same period in the prior year, an improvement of 350 basis points.

Total operating expenses for the nine months ended April 30, 2017 were $41.5 million, as compared to $44.0 million in the same period in the prior year, a reduction of $2.5 million or 5.8%.

Supplemental Non-GAAP Disclosures EBITDA and Adjusted EBITDA (Unaudited)

In addition to the financial measures prepared in accordance with generally accepted accounting principles, the Company uses EBITDA and Adjusted EBITDA, non-GAAP financial measures, to assess its performance. EBITDA represents earnings before interest income, interest expense, income tax expense, depreciation, and amortization of intangible assets. We define Adjusted EBITDA as EBITDA excluding the effects of SEC inquiry and financial restatement costs, strategic consulting and other related professional fees, executive severance and employee retention, restructuring, share-based compensation, impairment of goodwill and long-lived assets, unrealized foreign exchange gains and losses, net, other non-operating gains and losses, net, and gains and losses on investment in affiliates and impairments.

We believe that providing EBITDA and Adjusted EBITDA to investors is useful, as these measures provide important supplemental information of our performance to investors and permits investors and management to evaluate the operating performance of our core supply chain business. We use EBITDA and Adjusted EBITDA in internal forecasts and models when establishing internal operating budgets, supplementing the financial results and forecasts reported to our Board of Directors, determining a component of incentive compensation for executive officers and other key employees based on operating performance and evaluating short-term and long-term operating trends in our core supply chain business. We believe that EBITDA and Adjusted EBITDA financial measures assist in providing an enhanced understanding of our underlying operational measures to manage the core supply chain business, to evaluate performance compared to prior periods and the marketplace, and to establish operational goals. We believe that these non-GAAP financial adjustments are useful to investors because they allow investors to evaluate the effectiveness of the methodology and information used by management in our financial and operational decision-making.

EBITDA and Adjusted EBITDA are non-GAAP financial measures and should not be considered in isolation or as a substitute for financial information provided in accordance with U.S. GAAP. These non-GAAP financial measures may not be computed in the same manner as similarly titled measures used by other companies.

A table reconciling the Company’s EBITDA and Adjusted EBITDA to its GAAP net income (loss) is included in this release.
