HAUPPAUGE, N.Y.—(BUSINESS WIRE)—February 6, 2013— Globecomm Systems Inc. (NASDAQ:GCOM), a leading communications solutions provider, today reported financial results for the fiscal 2013 second quarter and six months ended December 31, 2012.

The following are highlights:

Fiscal Year 2013 Second Quarter Results

Revenues for the Company’s fiscal 2013 second quarter were $79.7 million as compared to $95.2 million in the same period last year, a decrease of 16.2%. Revenues from services were $50.2 million as compared to $54.7 million in the same period last year, a decrease of 8.2%. The decrease in service revenues reflects a decrease in our access service offering in the government marketplace due to the reduction of services in Iraq. Revenues from infrastructure solutions were $29.6 million as compared to $40.5 million in the same period last year, a decrease of 27.1%. The decrease in infrastructure revenues was due to reduction in revenue milestones under a major government program, which contributed $7.2 million in the second quarter as compared to $14.1 million in the same period last year.

Net income for the Company’s fiscal 2013 second quarter was $3.8 million, or $0.17 of diluted net income per common share, compared to net income of $9.3 million or $0.41 of diluted net income per common share in the same period last year. During the second quarter of fiscal 2012, the Company recorded a gain for the change in fair value of the ComSource earn-out as a result of a reduction in ComSource’s actual results and forecasted

performance. In accordance with GAAP, this change in the fair value of the earn-out resulted in a $4.1 million ($0.18 per diluted share) gain to net income. Adjusted diluted net income per common share for the second quarter of fiscal year 2013 was $0.17 compared to $0.23 in the same period last year. The reduction in adjusted diluted net income per common share was primarily driven by the reduction of revenues in both operating segments, partially offset by reductions in other operating expenses based on certain cost cutting initiatives.

Adjusted EBITDA for the second quarter of 2013 was $9.8 million as compared to $12.0 million in the same period last year. The Company’s operating cash flow for the quarter was $8.0 million as compared to $8.8 million in the same period last year.

Fiscal Year 2013 Six Month Results

Revenues for the Company’s fiscal 2013 six months ended December 31, 2012 were $160.9 million as compared to $166.2 million in the same period last year, a decrease of 3.2%. Revenues from services were $97.3 million as compared to $104.9 million in the same period last year, a decrease of 7.2%. The decrease in service revenues reflects a decrease in our access service offering in the government marketplace due to the reduction of services in Iraq. Revenues from infrastructure solutions were $63.6 million as compared to $61.3 million in the same period last year, an increase of 3.7%. The increase in infrastructure revenues was primarily driven by the achievement of revenue milestones under a major government program.

Net income for the Company’s fiscal 2013 six months ended December 31, 2012 was $6.5 million or $0.28 of diluted net income per common share compared to net income of $18.6 million, or $0.82 of diluted net income per common share in the same period last year. During the six months ended December 31, 2011, the Company recorded a gain for the change in fair value of the ComSource earn-out as a result of changes in ComSource’s actual results and forecasted performance. In accordance with GAAP, this change in the fair value of the earn-out resulted in a $10.6 million ($0.47 per diluted share) gain to net income. Adjusted diluted net income per common share for the fiscal year 2013 six months ended December 31, 2012 was $0.28 as compared to $0.35 in the same period last year. The reduction in adjusted diluted net income per common share was primarily driven by the reduction of service revenues, partially offset by reductions in other operating expenses based on certain cost cutting initiatives.

Adjusted EBITDA for the six months ended December 31, 2012 decreased to $17.8 million as compared to $20.2 million in the same period last year. The Company’s operating cash flow for the six months ended December 31, 2012 was $14.7 million as compared to $14.6 million in the same period last year.

Management’s Review of Results and Expectations

David Hershberg, Chairman and CEO, said: “This has been a challenging year for the Company due to a number of delays and uncertainties in awarding US Government contracts. We believe that when the budget is passed at a reasonable level that we will be in a good position moving forward. The Company’s diversified portfolio is helping to mitigate the effects of the current reduction in Government spending resulting from troop draw downs in Iraq and Afghanistan. While we continue to face some U.S. Government budget and economic headwinds, we remain focused on executing on our overall business plan and vision as we explore strategic alternatives to maximize shareholder value.”

Keith Hall, President and COO, added: “The Company continues to invest in a number of strategic initiatives including our Tempo Enterprise Media Platform and our Hosted Switch platforms, as we continue to increase the value proposition of our global network and our vision as an end to end data management services company. We continue to leverage this value proposition to enter new markets, as we diversify our customer base and build our recurring revenue streams. Most recently we have begun to leverage our capabilities within the Cyber Security arena. As Dave points out, this diversity continues to help mitigate the contraction of our business in Iraq and Afghanistan. Looking forward, I remain excited about our opportunities to grow.”

Management’s Current Expectations for the Fiscal Year Ending June 30, 2013

Globecomm currently expects the following financial results for the fiscal year 2013:

Non-GAAP Measures

Adjusted EBITDA is a non-GAAP measure which represents net income before interest income, interest expense, provision for income taxes, depreciation, amortization expense, non-cash stock compensation expense, and earn-out fair value adjustments. Globecomm believes this provides greater transparency by helping illustrate comparability between current and prior periods. Under an accounting pronouncement on business combinations, acquisition related costs are required to be expensed rather than capitalized, and changes to the fair value of earn-out payments must be recognized in earnings. Therefore, the exclusion of the earn-out fair value adjustments in the adjusted EBITDA calculation provides better comparability.

Adjusted EBITDA does not represent cash flows as defined by GAAP. Globecomm discloses adjusted EBITDA since it is a financial measure commonly used in its industry. Because adjusted EBITDA facilitates internal comparisons of our historical financial position and operating performance on a more consistent basis, the Company also uses adjusted EBITDA in measuring performance relative to that of our competitors and in evaluating acquisition opportunities. The Company’s management regularly uses supplemental non-GAAP financial measures internally to understand, manage and evaluate the Company’s business and make operating decisions. Adjusted EBITDA is not meant to be considered a substitute or replacement for net income as prepared in accordance with GAAP. Adjusted EBITDA may not be comparable to other similarly titled measures of other companies. Reconciliation between GAAP net income and adjusted EBITDA is provided in a table immediately following the Condensed Consolidated Balance Sheets.

Reconciliation of adjusted diluted net income per common share excludes earn-out fair value adjustments, which is. not in accordance with GAAP. However, Globecomm believes this measure provides greater transparency by helping illustrate comparability between current and prior periods. Non-GAAP financial measures are not meant to be considered in isolation or as a substitute for comparable GAAP measures, and should be read only in conjunction with the Company’s consolidated financial statements prepared in accordance with GAAP. The Company’s management regularly uses supplemental non-GAAP financial measures internally to understand, manage and evaluate the Company’s business and make operating decisions.
