Fiscal Year 2013 Fourth Quarter Results

Consolidated revenue for the Company’s fiscal 2013 fourth quarter was $80.6 million as compared to $104.8 million in the same period last year, a decrease of 23.1%. Revenues from services were flat at $50.0 million as compared to $50.1 million in the same period last year. Revenues from infrastructure solutions were $30.6 million as compared to $54.7 million in the same period last year, a decrease of 43.9%. The decrease in infrastructure solutions was primarily driven by the achievement of revenue milestones in the fourth quarter of fiscal 2012 of approximately $15.6 million under a major government program which was completed as of January 2013.

Net income for the Company’s fiscal 2013 fourth quarter was $4.6 million, or $0.20 of diluted net income per common share, compared to net income of $7.1 million, or $0.31 of 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. Excluding this gain, adjusted diluted net income per common share for the fourth quarter of fiscal year 2013 was $0.19 compared to $0.13 in the same period last year. The increase in adjusted diluted net income per common share was primarily driven by the increase in gross margin percentage in services and reductions in other operating expenses based on certain cost cutting initiatives, partially offset by the reduction of infrastructure revenue and gross margin percentage erosion based on additional costs incurred on certain fixed price contracts.

Adjusted EBITDA for the fourth quarter of 2013 was $10.3 million as compared to $9.1 million in the same period last year.

Fiscal Year 2013 Full Year Results

Consolidated revenue for the Company’s fiscal year ended June 30, 2013 was $319.6 million as compared to $381.9 million last year, a decrease of 16.3%. Revenues from services were $199.1 million as compared to $220.9 million last year, a decrease of 9.9%. The decrease in service revenues was primarily due to a non-recurring $12.5 million equipment sale by ComSource in the three months ended March 31, 2012 along with a decrease in the managed network service access product line in the government marketplace due to the reduction of services in Iraq and Afghanistan. Revenues from infrastructure solutions were $120.5 million as compared to $161.0 million in the same period last year, a decrease of 25.1%. The decrease in infrastructure solutions revenues was primarily driven by a reduction of $34.1 million due to the completion of a major government program in January 2013, this program had lower than normal margin. This program contributed $20.0 million in fiscal 2013 as compared to $54.1 million in fiscal 2012.

Net income for the Company’s fiscal 2013 year ended June 30, 2013 was $15.2 million, or $0.66 of diluted net income per common share, compared to net income of $28.6 million, or $1.26 of diluted net income per common share, last year. During 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. Excluding this gain, adjusted diluted net income per common share for the fiscal year 2013 year ended June 30, 2013 was $0.66 as compared to $0.74 last year. The reduction in adjusted diluted net income per common share was primarily driven by the reduction of infrastructure solutions revenue and gross margin percentage erosion based on additional costs incurred on certain fixed price contracts and the reduction of service revenues, partially offset by reductions in other operating expenses based on certain cost cutting initiatives and the increase in gross margin percentage in services.

Adjusted EBITDA for the year ended June 30, 2013 decreased to $38.5 million as compared to $42.6 million last year.

The Transaction

On August 26, 2013 the Company announced that an affiliate of Wasserstein & Co. has entered into a definitive agreement to acquire Globecomm for $14.15 per share in cash. The purchase price represents a premium of 21.9% over the closing price on January 14, 2013, the day on which Globecomm announced that it had retained Needham & Company to assist it in a review of potential strategic alternatives to enhance shareholder value. The transaction is valued at approximately $340 million.

As a result of that announcement, the Company has not provided guidance for fiscal 2014 and will not be hosting a conference call to discuss the fourth quarter and full year financial results.

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 the Company’s historical financial position and operating performance on a more consistent basis, the Company also uses adjusted EBITDA in measuring performance relative to that of the Company’s 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.
