MODUSLINK REPORTS 2014 FOURTH QUARTER AND FISCAL YEAR FINANCIAL RESULTS

—Company extends tax benefit preservation plan—

WALTHAM, Mass.—October 14, 2014—ModusLink Global Solutions™, Inc. (NASDAQ: MLNK) today reported financial results for its 2014 fourth quarter and fiscal year ended July 31, 2014. Results for those periods are summarized in the following paragraphs. For a full discussion of the results, please see the Company’s annual report on Form 10-K, which can be accessed through www.moduslink.com.

Fourth Quarter Financial Summary

ModusLink reported net revenue of $164.7 million for the fourth quarter of fiscal 2014, compared to $181.0 million in the fourth quarter of fiscal 2013. The change in net revenue was primarily driven by lower revenue from a computing client that primarily affected results in Asia, and lower volumes from an aftermarket services program related to the repair and refurbishment of mobile devices that affected results in the Americas.

Gross margin for the fourth quarter of fiscal 2014 was 8.8% compared to 11.1% in the fourth quarter of the previous year. The decline was primarily due to lower overall revenue, including revenue from the computing client noted above, partially offset by improved operating efficiencies. In the fourth quarter of the prior year, the Company recognized previously deferred revenue for a client program, which increased gross margin by 80 basis points for that period.

Operating loss for the fourth quarter of fiscal 2014 was $4.2 million, compared to $5.7 million in the fourth quarter of the previous year. Contributing to the reduced operating loss was an 80.3% decline in restructuring costs and a 13.1% decline in selling, general and administrative expenses (SG&A), which was primarily due to lower professional fees related to the financial restatement and employee related costs. Net loss for the fourth quarter of fiscal 2014 was $8.5 million, or $0.16 per share, compared with net loss of $8.8 million, or $0.17 per share.

For the fourth quarter of fiscal 2014, Adjusted EBITDA was $2.1 million compared to $6.9 million for the same period in fiscal 2013. EBITDA represents earnings before interest, income tax expense, depreciation and amortization, and Adjusted EBITDA represents EBITDA excluding certain items. Please refer to the non-GAAP information and table reconciling the Company’s Adjusted EBITDA to its GAAP net income/(loss) below.

The Company reported cash and cash equivalents of $183.5 million at July 31, 2014 compared to $77.9 million at July 31, 2013. At July 31, 2014, the Company reported trading securities of $22.8 million. The payment associated with the acquisition of the securities was not made by July 31, 2014 given that the majority of the related trades had not settled. Therefore, the liability associated with the payment is classified under other current liabilities on the Company’s balance sheet.

Fiscal Year 2014 Financial Summary

The Company reported net revenue of $723.4 million for 2014, compared to $754.5 million in fiscal 2013. The change in net revenue was driven by lower revenue from a software client that reorganized its supply chain, primarily affecting results in Europe. Results for fiscal 2014 benefited from significant revenue growth from a consumer electronics client, which primarily affected results in the Americas and Europe, and from an aftermarket services program related to the repair and refurbishment of mobile devices that affected results in the Americas.

Gross margin for fiscal 2014 was 10.3% compared to 9.9% in the previous year. The improvement was primarily due to a favorable revenue mix and cost reduction actions.

ModusLink reported operating loss for fiscal 2014 of $5.5 million, compared to operating loss of $28.2 million in the previous year. Contributing to the reduced operating loss was a 54.8% decline in restructuring costs and a 17.2% decline in SG&A, which was primarily due to lower professional fees (including audit fees and cost related to the financial restatement) and employee related costs. Net loss for fiscal 2014 was $16.3 million, or $0.32 per share, compared with net loss of $40.4 million, or $0.86 per share. For fiscal 2014, Adjusted EBITDA was $23.0 million compared to $17.2 million for fiscal 2013.

ModusLink Extends Tax Benefit Preservation Plan

ModusLink today announced that its Board of Directors approved a three-year extension of its current tax benefit preservation plan, which is designed to help preserve the value of its net operating losses and other deferred tax benefits.

The current plan, adopted in October 2011, had been scheduled to expire on October 17, 2014. As approved by the Board of Directors, the expiration date of the tax benefit preservation plan has been extended to October 17, 2017.

Non-GAAP Information

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

We believe that providing Adjusted EBITDA to investors is useful as this measure provides 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 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 the

Adjusted EBITDA financial measure assists 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.

Adjusted EBITDA is a non-GAAP financial measure and should not be considered in isolation or as a substitute for financial information provided in accordance with U.S. GAAP. This non-GAAP financial measure 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.
