(NASDAQ:GCOM), a leading global communications solutions provider, today announced financial results for the fiscal 2012 fourth quarter and fiscal year ended June 30, 2012.

The following are highlights.

Fiscal Year 2012 Fourth Quarter Results

Consolidated revenue for the Company’s fiscal 2012 fourth quarter increased 18.8% to $104.8 million as compared to $88.3 million in the same period last year. Infrastructure revenue increased 53.2% to a record $54.7 million, as compared to $35.7 million in the same period last year. The increase in infrastructure revenue was primarily driven by the achievement of revenue milestones under a major government contract which carries lower than traditional infrastructure margins. Service revenue has been somewhat impacted by the reduction of troops involved in conflicts in Iraq and Afghanistan.

Net income for the Company’s fiscal 2012 fourth quarter increased to $7.1 million, or $0.31 diluted net income per common share, as compared to net income of $2.2 million, or $0.10 diluted net income per common share, in the same period last year. During the fourth quarter of fiscal 2012, 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 $4.1 million ($0.18 per diluted share) gain to net income. In the same period last year, the Company recorded a $2.3 million charge ($0.10 per diluted share) relating to the earn-out of C2C and Evocomm. Excluding these charges, adjusted diluted net income per common share decreased 35.0% to $0.13 as compared to $0.20 in the same period last year.

Adjusted EBITDA for the Company’s fiscal 2012 fourth quarter decreased 11.0% to $9.1 million as compared to $10.2 million in the same period last year. The decreases in adjusted diluted net income per common share and adjusted EBITDA were attributed to services revenue and gross margin being somewhat impacted by the reduction of troops involved in conflicts in Iraq and Afghanistan.

Fiscal Year 2012 Full Year Results

Consolidated revenue for the Company’s fiscal year ended June 30, 2012 increased 39.3% to a record $381.9 million as compared to $274.2 million last year. Service revenue increased 17.1% to a record $220.9 million as compared to $188.7 million last year. The increase in service revenue was primarily driven by the Company’s acquisition of ComSource, contributing $27.6 million, along with an increase in our Access service offering, primarily in the government marketplace. Revenues from infrastructure solutions increased 88.3% to a record $161.0 million as compared to $85.5 million last year. The increase in infrastructure revenues was primarily driven by the achievement of revenue milestones under a major government contract which carries lower than traditional infrastructure margins.

Net income for the Company’s fiscal 2012 year ended June 30, 2012 increased to $28.6 million, or $1.26 per diluted share, as compared to net income of $9.0 million, or $0.41 per diluted share last year. During the Company’s fiscal year 2012 the Company recorded a gain of $11.9 million ($0.52 per diluted share) 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 the fiscal year ended June 30, 2011 the Company recorded a $4.8 million charge ($0.22 per diluted share) relating to the earn-out of C2C and Evocomm, $0.5 million ($0.02 per diluted) related to the acquisition related costs for ComSource, and a non-recurring tax benefit of $0.7 million ($0.03 per diluted share). Excluding these net adjustments, the Company’s adjusted diluted net income per common share for the fiscal year 2012 increased 19.4% to $0.74 from $0.62 last year. The increase in adjusted diluted net income per common share was primarily attributed to the Company’s acquisition of ComSource in April 2011.

Adjusted EBITDA for fiscal 2012 year ended June 30, 2012 increased to a record $42.6 million as compared to $33.9 million last year. The increase in adjusted EBITDA is primarily attributable to the increase in our Access service offering in the government marketplace coupled with the impact of the operating results of ComSource.

Management’s Review of Results and Expectations

David Hershberg, Chairman and CEO, said “Despite a challenging economic backdrop that continues to provide head winds for the Company’s infrastructure segment, Globecomm is proud to have completed yet another year of record revenues and adjusted EBITDA. Due to the uncertainty surrounding the U.S. Government’s budget environment, including the reduced Afghanistan commitment, fiscal 2013 will be a challenge to improve on the excellent results of fiscal 2012.”

Mr. Hershberg continued: “The balance sheet remains strong, with $58 million of net cash and we anticipate a strong cash flow in fiscal 2013. This will provide us ample liquidity to execute our overall business plan and vision. We continue to expand our sales force, invest in new products and expand the global service network foot print. Furthermore, we see excellent opportunity in the wireless, media and maritime vertical marketplaces and are well positioned in the government vertical if the budget situation is resolved. Our acquisitions continue to perform well and we are continuing our search for additional strategic acquisition opportunities. I want to thank the entire Globecomm team for an excellent year and look forward to a strong year ahead.”

Keith Hall, President and COO, added “Coming off a record year in fiscal 2012, we are excited about the investments we have made to develop our commercial market verticals. Key highlights include our first major TEMPO award and our contract with Ericsson to provide Machine to Machine managed services to up to 400 vessels. Globecomm has come a long way in the development of our value proposition as a global communication solution provider as evident by these awards. With the evolution of the Internet and mobile communications, we remain at the forefront of network and application innovation. Cloud and hybrid-satellite network opportunities are evolving based on this innovation and we continue to develop seamless experiences for our customers. As we enter fiscal 2013 we will continue to build upon this value proposition and are excited about the opportunities it will afford us.”

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, acquisition costs 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 acquisition related costs and 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 acquisition related costs, earn-out fair value adjustments and non-recurring tax adjustments. These amounts are not in accordance with GAAP. However, Globecomm believes this measure provides greater transparency by helping illustrate comparability between current and prior periods. The non-recurring tax adjustment primarily relates to research and development tax credits for fiscal years 2004, 2005 and 2010, therefore they have been excluded as a non-GAAP measure to provide better comparability of results. 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.
