Global Telecom & Technology Reports Fourth Quarter and Full Year 2009 Results

Generates Revenue of $64.2 Million and Doubles Adjusted EBITDA to $4.2 Million for the Year

Completes Acquisition of WBS Connect

MCLEAN, Va.—(BUSINESS WIRE)—March 23, 2010—Global Telecom & Technology, Inc. (“GTT”), (OTCBB:GTLT), a leading global network integrator that provides its clients with a broad portfolio of wide-area network, dedicated Internet access and managed data services, announced today results for the fourth quarter and year ended December 31, 2009. Highlights include:

• Revenue totaled $64.2 million as compared to $67.0 million for 2008. Revenue was negatively impacted by the substantial weakening of the Euro and British Pound Sterling to the U.S. Dollar since 2008. Adjusted for currency effects, revenue increased approximately 2% over 2008.

• Adjusted Earnings Before Interest Taxes Depreciation and Amortization (“EBITDA”)* doubled quarter-over-quarter and year-over-year. Fourth quarter 2009 increased to $1.2 million compared to $0.6 million in the fourth quarter of 2008. Full year 2009 increased to $4.2 million compared to $2.0 million in 2008.

• Acquisition of WBS Connect LLC completed on December 16, 2009, resulted in the addition of over 400 customers and a broader dedicated Internet access and Ethernet product suite.

• Net income of $0.5 million, or $0.03 per share for the full year 2009.

* See “Annex A: Non-GAAP Financial Information—Adjusted EBITDA” for more information regarding the computation of Adjusted EBITDA.

“With $16.4 million in revenue and $1.2 million in Adjusted EBITDA, the fourth quarter was a solid finish to what was a strong year for GTT,” stated Richard D. Calder, Jr., president and chief executive officer. “We have continued to generate improving financial results, with our Adjusted EBITDA continuing on a steady sequential incline and doubling the amount we reported for both the fourth quarter and full year in 2008.

“With our acquisition of WBS Connect completed in the fourth quarter, we have achieved a significant milestone in our strategy to scale our business and create operational leverage. The addition of WBS’s network assets also expanded our capability to offer a broader suite of dedicated Internet access and Ethernet services, providing the opportunity to attract new customers and cross-sell into our existing customer base. We have made excellent progress integrating WBS since closing the transaction, and are pleased to see strong contributions to our new sales, including recently announced dedicated Internet access deals with Telx and other large Ethernet transport installations.”

“During the past two years, GTT has produced growing Adjusted EBITDA results,” said Eric Swank, chief financial officer. “This continuous improvement in our cost controls and operational efficiencies has provided us with the capital and credit that is funding our acquisitions. This improvement is enabled by GTT’s operational platform – an experienced global sales force, exceptional global customer and network operations teams, and a proprietary Client Management Database (CMD) integrated support system – which also positions us further to scale our business.

“To that end, our previously announced and pending acquisition of assets from Global Capacity has received FCC approval and continues to move toward closure upon receipt of final customer and vendor consents. We believe these assets are an excellent complement to our existing business and can further demonstrate the power of our operating platform in our drive to build a larger, more profitable company.”

ANNEX A: Non-GAAP Financial Information

Adjusted EBITDA

Adjusted EBITDA represents operating income before depreciation and amortization on a non-GAAP (accounting principles generally accepted in the United States of America) combined basis for the periods presented, and adjusted to exclude certain one-time expenses including costs associated with employee terminations and other non-recurring items and non-cash compensation. GTT presents Adjusted EBITDA as a supplemental measure of GTT’s performance. GTT also presents Adjusted EBITDA because GTT believes it is frequently used by securities analysts, investors and other interested parties in the evaluation of companies in its industry and in measuring the ability of issuers to meet debt service obligations.

In evaluating Adjusted EBITDA, you should be aware that in the future GTT may incur expenses similar to the adjustments in this presentation. GTT’s presentation of Adjusted EBITDA should not be construed as an inference that GTT’s future results will be unaffected by unusual or non-recurring items. Adjusted EBITDA is not a measurement of GTT’s financial performance under GAAP and should not be considered as an alternative to net income, operating income or any other performance measures derived in accordance with GAAP.

The following is a reconciliation of Adjusted EBITDA to operating income (loss) (in thousands):

	Three Months Ended				Twelve Months Ended
	December 31,				December 31,
	2009		2008		2009		2008
Operating income (loss)	$	83	$	163	$	1,295	$	(42,856	)
Depreciation and amortization		386		399		1,733		2,211
Impairment of goodwill and intangible assets		—		—		—		41,854
Restructuring costs, employee termination and non-recurring items		641		—		641		—
Non-cash compensation		130		71		550		813
Adjusted EBITDA	$	1,240	$	633	$	4,219	$	2,022
