Global Telecom & Technology Reports First Quarter 2010 Results

Revenue Increases 31% to $20.6 Million

Adjusted EBITDA Increases 123% to $1.6 Million

MCLEAN, Va.—(BUSINESS WIRE)—May 12, 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 financial results for the first quarter ended March 31, 2010. Highlights for the quarter include:

• Revenue increased by 31 percent to $20.6 million as compared to $15.7 million for the first quarter 2009.

• Gross margin of 27.5 percent increased compared to 27.0 percent in the first quarter of 2009.

• Selling, general and administrative (“SG&A”) expenses, excluding non-cash compensation, decreased to 19.7 percent of revenue, compared to 22.4 percent in the first quarter of 2009.

• Adjusted Earnings Before Interest Taxes Depreciation and Amortization (“EBITDA”)* increased 123 percent to $1.6 million compared to $0.7 million in the first quarter of 2009.

• Net income increased to $0.2 million, or $0.01 earnings per share, compared with a net loss of $0.1 million, or a loss per share of $0.01 in the first quarter of 2009.

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

“We had a good start to the year,” stated Richard D. Calder, Jr., president and chief executive officer. “Our solid results in the first quarter are evidence of the success of our strategy to scale our business, leverage our operational platform and increase profitability. The acquisition and successful integration of WBS Connect at the end of last year has helped us drive significant revenue and Adjusted EBITDA growth. The expanded services portfolio and network assets we gained through the acquisition of WBS Connect have also promoted new opportunities, and during the quarter we closed a number of new sales.”

“With respect to the WBS Connect integration, we have made tremendous progress in absorbing the business into our systems and platforms in a very short period,” said Eric Swank, chief financial officer. “All of the WBS Connect operational data has been fully integrated into GTT’s client management database, or CMD, ahead of schedule. Due to our determined efforts to rapidly integrate, we have achieved cost savings that are reflected in our continually improving EBITDA performance.”

The Company also announced that investors representing approximately $2.5 million of aggregated proceeds from the Company’s February 8, 2010 $5 million units offering, who had a right to receive a refund of their investment following the expiration of the Global Capacity asset purchase agreement, have waived the right to receive their refund and elected to retain some or all of their securities. The $2.5 million proceeds from securities sold and retained by investors are included in the Company’s unrestricted cash at March 31, 2010.

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 (amounts in thousands):

	Three Months Ended
	March 31,
	2010		2009
Operating income	$	656	$	110
Depreciation and amortization		738		445
Non-cash compensation		211		166
Adjusted EBITDA	$	1,605	$	721
