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.
