Q4 FY10 Financial Highlights

• Total revenues for the quarter and fiscal year ended March 31, 2010 were $82.5 million, representing increases of 11% compared to the third quarter of fiscal 2010 and 20% over the previous fiscal year, respectively. Total revenues for the fiscal year ended March 31, 2010 were $292.3 million, representing a 17% increase over the prior fiscal year.

• EBITDA, as adjusted, for the fourth quarter was $26.5 million, representing a 20% year-over-year increase and a 34% sequential increase; EBITDA, as adjusted, for fiscal year 2010 was $81.0 million, representing a 32% increase over the prior fiscal year. EBITDA, as adjusted, is defined as income (loss) from operations less depreciation, amortization, integration expenses, certain legal and professional costs, litigation and employment settlements, share-based payments, including share-settled liabilities and other non-cash expenses. EBITDA, as adjusted, should be considered in addition to, but not in lieu of, income (loss) from operations reported under generally accepted accounting principles (GAAP).

• Income from operations for the fourth quarter was $12.4 million, representing a 15% year-over-year increase.

• Gross profit margins, excluding depreciation and amortization, were 50% for the quarter and 45% for the fiscal year ended March 31, 2010.

• Cross connects billed to customers increased to 9,154 as of March 31, 2010 from 8,883 the previous quarter and 8,339 a year earlier, representing increases of 3% and 10%, respectively.

• Utilization of total colocation space utilization was 29.0% as of March 31, 2010. Utilization of built-out colocation space was 54.4% as of March 31, 2010.

Q4 FY10 Business Highlights

• Terremark increased the annualized cloud computing run rate to $21.9 million during the fourth quarter, a 27% increase from the previous quarter. The company’s cloud computing solutions continue to gain traction with Fortune 500 enterprises and federal government agencies looking to deploy and manage applications faster, while substantially reducing their total cost of ownership.

• During the quarter ended March 31, 2010, Terremark added 56 new customers, for a total of 1,350 customers at the end of the period.

• Terremark had another quarter of record bookings with $45.5 million of new annual contract value booked in the quarter ended March 31, 2010. The company had $30.1 million of recurring bookings in the quarter, also the best in the company’s history.

• Terremark recently announced the launch of the third datacenter at its Network Access Point (NAP) of the Capital Region campus. With more than 65 percent of the available datacenter space at the campus contracted, including the recently launched third datacenter, the company acquired 27 acres of land adjacent to the campus to accommodate future success-based growth. The $5-million land acquisition provides Terremark the ability to add at least 250,000 square feet of high-quality datacenter space and close to 100,000 square feet of Class A office space, effectively doubling the size of the campus. Terremark also unveiled the NAP of the Capital Region’s 72,000-square-foot headquarters building, which includes a 150-seat auditorium built to the Federal government’s Physical Security Standards for Sensitive Compartmented Information Facilities (SCIF) and approximately 50,000 square feet of Class A office space that can be built to SCIF specifications in order to meet customer demands.

Business Outlook

• For the first quarter of fiscal 2011, the Company expects revenues to range from $77 million to $79 million and EBITDA, as adjusted, to range from $18 million to $20 million.

• For the full 2011 fiscal year, the Company raises guidance of revenues to range from $338 million to $343 million and EBITDA, as adjusted, to range from $98 million to $101 million.

The foregoing statements regarding targets for the quarter and full year are forward-looking and actual results may differ materially. These are the Company’s targets, not predictions of actual performance.

Statements contained in this press release may constitute “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995.

Non-GAAP Financial Measures

Terremark continues to provide all information required in accordance with generally accepted accounting principles (GAAP), but it believes that evaluating its ongoing operating results may be difficult if limited to reviewing only GAAP financial measures. Accordingly, Terremark uses non-GAAP financial measures, such as EBITDA, as adjusted. In presenting these non-GAAP financial measures, Terremark excludes certain items that it believes are not good indicators of the Company’s current or future operating performance. These items are depreciation, amortization, integration expenses, certain legal and professional costs, litigation and employment settlements, share-based payments, including share-settled liabilities and other non-cash expenses.

Terremark intends to calculate the various non-GAAP financial measures in future periods on a basis consistent with its calculation of those measures for the three and twelve months ended March 31, 2010 and 2009 and the three months ended December 31, 2009, presented within this press release.
