Macquarie Telecom Group Limited revised earnings guidance for the second half of 2014. For the period, as a result of the impact of the technology migration in the core managed hosting business and the lower than anticipated mobile margins in the second half, the company's earnings before interest, tax, depreciation and amortization (EBITDA) is expected to reduce from previous guidance to a flat half on half result for fiscal 2014 with EBITDA profit now expected to be between $25 million and $27 million. Significant progress has been made in the second half of fiscal 2014 to provision and commence realizing the revenue streams of the large Federal Government customers won under the Australian Government's Lead Agency Secure Internet Gateway program.
