Adjusted EBITDA margin was 52.3% in the third quarter of 2007 compared to 49.4% in the year earlier period.

Net interest expense, excluding amortization of deferred financing fees and the impact of interest rate hedging, was $20.3 million in the third quarter of 2007, compared to $25.8 million in the year earlier period.

Equity free cash flow (as defined below) for the quarter ended September 30, 2007 was $30.2 million compared to $19.0 million in the year earlier period.

"SBA delivered another strong quarter," commented Jeffrey A. Stoops, President and Chief Executive Officer. "Operationally, our wireless carrier customers were materially more active in the third quarter compared to the first half of 2007, and we enjoyed our strongest lease-up quarter in over two years. Third quarter lease-up will be partially reflected in our fourth quarter financial results and fully reflected in our 2008 results. Our customers continue to remain very active, at an elevated pace compared to the first half of 2007, and we expect they will continue to remain very active through the end of this year and into 2008.

"We continue to be active growing our Company and increasing the size of our tower portfolio with quality tower assets that meet our expected return requirements. We expect to exceed our portfolio growth goals for 2007, and believe that we are well positioned to grow our portfolio by 5% to 10% or more in 2008. Our focus on organic growth, portfolio growth and capital structure is working well, and we achieved our overall goal of material growth in equity free cash flow per share. We feel very good about 2008. Our 2008 guidance calls for an acceleration of growth in leasing revenue, tower cash flow and adjusted EBITDA. We expect to once again achieve material growth in equity free cash flow per share in 2008."

Investing Activities

During the third quarter of 2007, SBA purchased 227 towers and built 17 towers, and as of September 30, 2007 SBA owned 6,026 towers. The 227 towers were purchased for an aggregate amount of $100.3 million, of which $43.3 million was paid in cash and the remainder through the issuance of shares of SBA common stock. Total cash capital expenditures for the third quarter of 2007 were $60.8 million, consisting of $1.8 million of non-discretionary cash capital expenditures (tower maintenance and general corporate) and $59.0 million of discretionary cash capital expenditures (new tower builds, tower augmentations, tower acquisitions and related earn-outs, and ground lease purchases). The Company spent $6.3 million purchasing land and easements, and extending lease terms, with respect to land underlying its towers.

Since September 30, 2007, SBA has purchased 19 additional towers. The 19 towers were purchased for an aggregate amount of $7.6 million, of which $6.5 million was paid in cash and the remainder through the issuance of shares of SBA common stock. The Company has agreed to purchase an additional 207 towers for an aggregate amount of $142.6 million, approximately one-half of which the Company intends to pay with cash and the remainder through the issuance of shares of SBA common stock. The Company anticipates that these acquisitions will be consummated by the end of the first quarter of 2008.

Financing Activities and Liquidity

SBA ended the third quarter with $1.555 billion of commercial mortgage-backed pass-through certificates outstanding, $350.0 million of 0.375% Convertible Senior Notes, and net debt of $1.71 billion.

Information on non-GAAP financial measures is presented below under "Non-GAAP Financial Measures." This press release will be available on our website at www.sbasite.com.

For additional information about SBA, please contact Pam Kline, Vice-President-Capital Markets, at (561) 226-9232, or visit our website at www.sbasite.com.

SBA is a leading independent owner and operator of wireless communications infrastructure in the United States. SBA generates revenue from two primary businesses - site leasing and site development services. The primary focus of the Company is the leasing of antenna space on its multi-tenant towers to a variety of wireless service providers under long-term lease contracts. Since it was founded in 1989, SBA has participated in the development of over 25,000 antenna sites in the United States.

Non-GAAP Financial Measures

Segment Operating Profit and Segment Operating Profit Margin

This press release includes disclosures regarding our Site Leasing Segment Operating Profit and Site Development Segment Operating Profit, which are non-GAAP financial measures. Each respective Segment Operating Profit is defined as segment revenue less segment cost of revenue (excluding depreciation, accretion and amortization) and Segment Operating Profit Margin is defined as Segment Operating Profit divided by segment revenue. Total Segment Operating Profit is the total of the Segment Operating Profits of the two segments. Segment Operating Profit and Segment Operating Profit Margin are, in our opinion, indicators of the operating performance of our site leasing and site development segments and each is used to provide management with the ability to monitor the operating results and margin of each segment, while excluding the impact of depreciation, accretion and amortization, which is largely fixed. Segment Operating Profit and Segment Operating Profit Margin are not intended to be alternative measures of revenue, segment gross profit or segment gross profit margin as determined in accordance with GAAP.

The Non-GAAP measurements of Segment Operating Profit and Segment Operating Profit Margin have certain material limitations. Specifically these measurements do not include depreciation, accretion or amortization expense. As we use capital assets in our business, depreciation, accretion and amortization expense is a necessary element of our costs and ability to generate profits. Therefore, any measure that excludes depreciation, accretion and amortization expense has material limitations. We compensate for these limitations by using Segment Operating Profit and Segment Operating Profit Margin as only two of several comparative tools, together with GAAP measurements, to assist in the evaluation of the operating performance of our segments.

The reconciliation of Site Leasing Segment Operating Profit and Site Development Segment Operating Profit and the calculation of Segment Operating Profit Margin are as follows:

 (1) Site leasing revenue growth percentage (as adjusted) over the
     year earlier period is calculated by taking actual site leasing
     revenue for the three months ended September 30, 2007,
     subtracting the site leasing revenue (as adjusted) for the three
     months ended September 30, 2006 and dividing the total by the
     site leasing revenue (as adjusted) for the three months ended
     September 30, 2006.

Tower Cash Flow and Tower Cash Flow Margin

This press release, including our fourth quarter 2007, full year 2007 and full year 2008 Outlook includes disclosures regarding Tower Cash Flow and Tower Cash Flow Margin, which are non-GAAP financial measures. Tower Cash Flow is defined as Site Leasing Segment Operating Profit excluding non-cash leasing revenue and non-cash ground lease expense and Tower Cash Flow Margin is defined as Tower Cash Flow divided by the sum of site leasing revenue minus non-cash site leasing revenue. We discuss these non-GAAP financial measures because we believe these items are indicators of performance of our site leasing operations. In addition, Tower Cash Flow is a component of the calculation often used by lenders to determine the availability of credit for our Company. Neither Tower Cash Flow nor Tower Cash Flow Margin are intended to be alternative measures of site leasing gross profit nor of site leasing gross profit margin as determined in accordance with GAAP.

The Non-GAAP measurements of Tower Cash Flow and Tower Cash Flow Margin have certain material limitations. Specifically these measurements do not include leasing revenue of a non-cash nature and ground lease expense of a non-cash nature. Because these non-cash leasing revenue and non-cash ground lease expenses reflect the straight-line impact of the tenant leases and ground leases associated with our site leasing operations, any measure that excludes these non-cash items has material limitations. We compensate for these limitations by using Tower Cash Flow and Tower Cash Flow Margin as only two of several comparative tools, together with GAAP measurements, to assist in the evaluation of the profitability of our site leasing operations.

The reconciliation of Tower Cash Flow is as follows:

Adjusted EBITDA, Annualized Adjusted EBITDA and Adjusted EBITDA Margin

This press release, including our fourth quarter 2007, full year 2007 and full year 2008 Outlook, includes disclosures regarding Adjusted EBITDA, Annualized Adjusted EBITDA and Adjusted EBITDA Margin. Adjusted EBITDA is defined as loss from continuing operations plus net interest expenses, provision for taxes, depreciation, accretion and amortization, asset impairment and other charges, non-cash compensation, loss from write-off of deferred financing fees and extinguishment of debt, and other expense and excluding non-cash leasing revenue, non-cash ground lease expense, other income and one-time costs related to transition and integration costs in connection with the AAT acquisition. We have included these non-GAAP financial measures because we believe these items are indicators of the profitability and performance of our core operations and reflect the changes in our operating results. Annualized Adjusted EBITDA is calculated as Adjusted EBITDA for the most recent quarter multiplied by four. Adjusted EBITDA Margin is defined as Adjusted EBITDA divided by the sum of total revenues minus non-cash leasing revenue. In addition, Adjusted EBITDA is a component of the calculation often used by lenders to determine the availability of credit for our Company. Neither Adjusted EBITDA, Annualized Adjusted EBITDA nor Adjusted EBITDA Margin are intended to be alternative measures of operating income or gross profit margin as determined in accordance with GAAP.

The Non-GAAP measurements of Adjusted EBITDA, Annualized Adjusted EBITDA and the Adjusted EBITDA Margin have certain material limitations, including the following:



 --  They do not include interest expense. Because we have borrowed
     money in order to finance our operations, interest expense is a
     necessary element of our costs and ability to generate profits
     and cash flows. Therefore any measure that excludes interest
     expense has material limitations;

 --  They do not include depreciation, accretion and amortization
     expense. As we use capital assets, depreciation, accretion and
     amortization expense is a necessary element of our costs and
     ability to generate profits. Therefore any measure that excludes
     depreciation, accretion and amortization expense has material
     limitations;

 --  They do not include provision for taxes. Because the payment of
     taxes is a necessary element of our costs, particularly in the
     future, any measure that excludes tax expense has material
     limitations;

 --  They do not include non-cash expenses such as asset impairment
     and other charges, non-cash compensation, other expense/income,
     non-cash leasing revenue and non-cash ground lease expense.
     Because these non-cash items are a necessary element of our costs
     and our ability to generate profits, any measure that excludes
     these non-cash items has material limitations. 

 --  They do not include one-time costs related to transition and
     integration costs incurred in connection with the AAT
     acquisition. Because these items are indicative of actual
     expenses incurred by the Company, any measure that excludes these
     costs has material limitations.

We compensate for these limitations by using Adjusted EBITDA, Annualized Adjusted EBITDA and Adjusted EBITDA Margin as only three of several comparative tools, together with GAAP measurements, to assist in the evaluation of our profitability and operating results.

The reconciliation of Adjusted EBITDA and the calculation of Annualized Adjusted EBITDA are as follows:

Net Debt and Leverage Ratio

This press release includes disclosures regarding Net Debt and Leverage Ratio. Net Debt is defined as debt minus cash and cash equivalents, short-term restricted cash and short-term investments. Leverage Ratio is defined as Net Debt divided by Annualized Adjusted EBITDA. We have included these non-GAAP financial measures because we believe these items are indicators of our financial condition. The non-GAAP measurements of Net Debt and Leverage Ratio have certain material limitations. Specifically these measurements exclude cash and cash equivalents, short-term restricted cash and short-term investments thereby reducing our debt position. Because we may not be able to use our cash to reduce our debt on a dollar-for-dollar basis, this measure may have material limitations. In addition, since a component of our Leverage Ratio is Annualized Adjusted EBITDA, this measure is subject to the same material limitations associated with Adjusted EBITDA. We compensate for these limitations by using Net Debt and our Leverage Ratio as only two of several comparative tools, together with GAAP measurements, to assist in the evaluation of our financial condition.

The calculations of Net Debt and Leverage Ratio are as follows:

Equity Free Cash Flow and Equity Free Cash Flow Per Share

This press release, including our fourth quarter 2007, full year 2007 and full year 2008 Outlook, also includes disclosures regarding Equity Free Cash Flow and Equity Free Cash Flow Per Share which are non-GAAP financial measures. Equity Free Cash Flow is defined as Adjusted EBITDA minus net interest expense, non-discretionary cash capital expenditures and cash taxes paid. Equity Free Cash Flow Per Share is defined as Equity Free Cash Flow divided by the weighted average shares outstanding for the period. We discuss Equity Free Cash Flow and Equity Free Cash Flow Per Share because we believe that these measures are indicators of the amount of cash produced by our business and thus reflects the amount that may be available for reinvestment in the business through discretionary capital expenditures, repayment of indebtedness or return to shareholders. Equity Free Cash Flow is not intended to be an alternative measure of cash flow from operations or operating income as determined in accordance with GAAP. Equity Free Cash Flow Per Share is not intended to be an alternative measure of earnings per share as determined in accordance with GAAP.

The use of Equity Free Cash Flow and Equity Free Cash Flow Per Share has certain material limitations. Specifically these measurements do not include discretionary capital expenditures. Because the determination of which capital expenditures are discretionary is subject to various interpretations and because these types of capital expenditures are an integral part of our plans for growth, any measure that excludes these items has material limitations. Furthermore, as the calculations of Equity Free Cash Flow and Equity Free Cash Flow Per Share are based on our Adjusted EBITDA, this measure is subject to the same material limitations associated with Adjusted EBITDA. In addition, by using Adjusted EBITDA as the starting point rather than cash flow from operating activities, timing differences on the cash receipts and disbursements of a number of items, primarily in working capital, are not captured. We compensate for these limitations by using Equity Free Cash Flow and Equity Free Cash Flow Per Share as only two of several comparative tools, together with GAAP measurements, to assist in the evaluation of our cash flow from operations.

The reconciliation of Equity Free Cash Flow is as follows:
