Global Telecom & Technology Reports First Quarter 2011 Results

Strong Sales Quarter Drives Robust Backlog

Earnings Per Share Triples

MCLEAN, Va.--(BUSINESS WIRE)--May 11, 2011--Global Telecom & Technology, Inc. (“GTT”), (OTCBB: GTLT), a global telecommunications carrier and leading network integrator serving the data communications needs of large enterprise, government and carrier clients, announced today financial results for the three months ended March 31, 2011. Financial highlights and historical comparisons include (in millions, except per share data):

“GTT completed one of its strongest sales quarters on record to start 2011,” said Richard D. Calder Jr., President and Chief Executive Officer. “We exited the first quarter with a very robust backlog of newly contracted services which we are aggressively working to implement. One of our largest wins plays firmly to GTT’s strengths, which is a large and complex network for a government end-user with locations in several emerging markets. While the significant installation interval on this particular project impacts revenue over the short-term, we are pleased by the long term revenue and profit trajectory a project such as this drives.”

“We continued to drive bottom-line performance during the first quarter as we advanced each of our key profitability metrics year-over-year, including tripling our earnings per share to $0.03,” stated Eric Swank, Chief Financial Officer. “As a result of the operating cash flow our business produces, we reduced our line of credit balance by $0.8 million and paid down our term loan by $0.5 million. This de-leveraging translates into accretion for our equity stakeholders and a stronger balance sheet as we drive our acquisition strategy.”

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):
