BOCA RATON, Fla., Aug. 4, 2008 (PRIME NEWSWIRE) -- SBA Communications Corporation (Nasdaq:SBAC) ("SBA" or the "Company") today reported results for the quarter ended June 30, 2008. Highlights of the results include:


   o  Second quarter over year earlier period:
      * Site leasing revenue growth of 17.8%
      * Tower cash flow growth of 23.8%
      * Operating income growth of $3.0 million
      * Net loss increased from $15.1 million to $18.4 million
      * Adjusted EBITDA growth of 23.4%
      * Equity Free Cash Flow per share growth of 25.0%

Operating Results

Total revenues in the second quarter of 2008 were $112.0 million, compared to $100.3 million in the year earlier period, an increase of 11.6%. Site leasing revenue of $93.7 million was up 17.8% over the year earlier period and site leasing segment operating profit (as defined below) of $71.1 million was up 21.9% over the year earlier period. Site leasing contributed 98.0% of the Company's total segment operating profit in the second quarter of 2008.

Tower Cash Flow (as defined below) for the quarter ended June 30, 2008, was $71.8 million, a 23.8% increase over the year earlier period. Tower Cash Flow margin for the three months ended June 30, 2008 was 78.1%, compared to 75.0% in the year earlier period.

Site development revenues were $18.2 million in the second quarter of 2008 compared to $20.7 million in the year earlier period, a 12.2% decrease due primarily to the substantial slowdown in second quarter activity of a single, previously sizeable, services customer of the Company. Site development segment operating profit margin was 7.9% in the second quarter of 2008, compared to 13.0% in the year earlier period.

Selling, general and administrative expenses were $12.5 million in the second quarter of 2008, compared to $11.6 million in the year earlier period. Included in selling, general and administrative expenses were non-cash compensation charges of $2.4 million and $2.1 million in the second quarter of 2008 and 2007, respectively. Net loss for the second quarter of 2008 was $18.4 million or $0.17 per share, compared to a net loss of $15.1 million or $0.15 per share in the year earlier period. Included in net loss is a $2.5 million, other-than-temporary impairment charge associated with the Company's auction rate securities. Excluding such charge, net loss per share was $0.15. At June 30, 2008, such securities had a par value of $29.8 million and a fair value of $9.3 million.

Adjusted EBITDA (as defined below) in the second quarter was $63.5 million, compared to $51.5 million in the year earlier period, a 23.4% increase. Adjusted EBITDA margin was 57.7% in the second quarter of 2008 compared to 52.5% in the year earlier period.

Net cash interest expense, excluding amortization of deferred financing fees and the impact of interest rate hedging was $23.7 million in the second quarter of 2008, compared to $20.0 million in the year earlier period.

Equity free cash flow (as defined below) for the quarter ended June 30, 2008 was $37.9 million compared to $29.0 million in the year earlier period. Equity free cash flow per share was $0.35 in the quarter ended June 30, 2008 compared to $0.28 per share in the year earlier period, an increase of 25%.

"SBA enjoyed another strong quarter of leasing results," commented Jeffrey A. Stoops, President and Chief Executive Officer. "Organic site leasing and tower cash flow growth continued to be very solid, reflecting strong ongoing wireless customer demand for network improvement and expansion. We believe that demand will continue to be strong for the foreseeable future, and that belief is the foundation behind our desire to continue to grow our tower portfolio with quality assets. In 2008, we expect to invest approximately $1 billion in towers and related assets, materially increasing our operations, site leasing revenue, tower cash flow, adjusted EBITDA and ultimately equity free cash flow per share. We believe these investments, together with our existing portfolio of quality towers, will enjoy significant customer demand for additional tower space in 2009, 2010 and beyond as wireless carriers continue to improve their existing networks, in some cases expand into new markets and ultimately deploy next generation technologies. To facilitate these activities, in the second quarter we raised an additional $550.0 million of attractively-priced capital which we have subsequently committed to invest in growth assets. We are very excited about our future, and our ability to deliver superior growth in equity free cash flow per share."

Investing Activities

During the second quarter of 2008, SBA purchased 555 towers (including those from TowerCo LLC) and built 18 towers, and as of June 30, 2008, SBA owned 6,896 towers. The 555 towers were purchased for an aggregate amount of $262.4 million of which $243.7 million was paid in cash and the remainder through the issuance of 519,000 shares of SBA Class A common stock. Total cash capital expenditures for the second quarter of 2008 were $264.5 million, consisting of $1.5 million of non-discretionary cash capital expenditures (tower maintenance and general corporate) and $263.0 million of discretionary cash capital expenditures (new tower builds, tower augmentations, tower acquisitions and related earn-outs, and ground lease buyouts). During the second quarter, the Company spent $5.9 million purchasing land and easements and extending lease terms with respect to land underlying its towers.

On July 18, 2008, the Company entered into a definitive merger agreement with Optasite Holding Company, Inc. ("Optasite") pursuant to which Optasite will become a wholly-owned subsidiary of SBA. As consideration for the merger, the Company will issue 7.25 million shares of its Class A common stock to the stockholders of Optasite, which shares will be subject to certain volume limitations on transfers. In addition, the Company will assume Optasite's fully drawn $150.0 million senior credit facility, which will remain outstanding, and approximately $25.0 million of additional liabilities, which SBA anticipates satisfying with cash on hand contemporaneously with the closing. At closing, Optasite is anticipated to own approximately 542 wireless communications towers and have approximately 43 managed site locations. The Company anticipates that this acquisition will be consummated on or before September 30, 2008.

On July 21, 2008, the Company entered into an agreement with Light Tower LLC pursuant to which SBA will acquire Light Tower Wireless LLC, the wireless infrastructure subsidiary of Light Tower LLC. Light Tower Wireless currently owns 340 wireless communications towers, five managed sites and five distributed antenna system ("DAS") networks. The purchase price to be paid by SBA will be either (i) $204.0 million in cash plus 1.15 million shares of SBA Class A common stock, which shares shall be subject to certain volume limitations on transfers or, (ii) in the alternative at the seller's option, $224.0 million in cash. All cash to be paid by SBA shall be paid from a combination of existing cash resources and a draw under SBA's existing senior credit facility. The Company anticipates that this acquisition will be consummated on or before October 31, 2008.

Since June 30, 2008, SBA has purchased 8 additional towers and 1 managed site. The 8 towers and 1 managed site were purchased for an aggregate amount of $5.4 million, of which $1.6 million was paid in cash and the remainder through the issuance of SBA Class A common stock. In addition to the Optasite and Light Tower transactions discussed above, the Company has agreed to purchase up to 75 additional towers for an aggregate amount of up to approximately $24.7 million, the substantial majority of which may be paid, at SBA's option, through the issuance of SBA's Class A common stock. The Company anticipates that these acquisitions will be consummated by the end of 2008.

Financing Activities and Liquidity

SBA ended the second quarter with $1.555 billion of commercial mortgage-backed pass-through certificates outstanding, $350.0 million of 0.375% Convertible Senior Notes, $550.0 million of 1.875% Convertible Senior Notes, no amounts borrowed under the Company's senior credit facility and net debt of $2.2 billion. At June 30, 2008, cash and cash equivalents and short-term restricted cash was approximately $242.5 million. At June 30, 2008, the Company's net debt and net secured debt to Annualized Adjusted EBITDA leverage ratios were 8.7x and 5.2x, respectively. The Company's auction rate securities are not counted in the Company's liquidity and net-debt calculations. As of the date of this press release, availability under the senior credit facility was approximately $278.9 million.

On May 16, 2008, the Company sold $550.0 million of 1.875% Convertible Senior Notes due 2013 in a private transaction. The notes will pay interest semi-annually at a rate of 1.875% per annum. The notes will be convertible, at the holder's option, under certain circumstances at an initial conversion rate of 24.1196 shares of SBA's Class A common stock per $1,000 principal amount of notes. This is equivalent to an initial conversion price of approximately $41.46 per share or a 20% conversion premium based on the last reported sale price of $34.55 per share of SBA's Class A common stock on May 12, 2008. Upon conversion, SBA's conversion obligation may be settled in cash, shares of SBA's Class A common stock, or a combination of cash and shares of SBA's Class A common stock. In connection with the issuance of the notes, SBA entered into convertible note hedge transactions. The convertible note hedge transactions have an initial strike price equal to the conversion price of the notes. Separately and concurrently, SBA also entered into warrant transactions which have an initial strike price of $67.37 per share. The convertible note hedge transactions and the sold warrant transactions, taken as a whole, effectively increase the conversion price of the notes from $41.46 per share to $67.37 per share and minimize the dilution risk associated with early conversion of the notes until such time that our Class A common stock is trading at a price above $67.37 per share. SBA used $120.0 million of the net proceeds from the note offering to repurchase 3.47 million shares of its Class A common stock and approximately $235.0 million to repay amounts outstanding under the senior credit facility arising from the TowerCo acquisition. As of June 30, 2008, the Company had 105.9 million shares of Class A common stock outstanding.

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 35,000 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:

Tower Cash Flow and Tower Cash Flow Margin

This press release, including our third quarter 2008 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 used by our lenders to determine compliance with our senior credit facility. 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 third quarter 2008 and full year 2008 Outlook, includes disclosures regarding Adjusted EBITDA, Annualized Adjusted EBITDA and Adjusted EBITDA Margin. Adjusted EBITDA is defined as net loss excluding the impact of 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, other income and expense (including in the second quarter of 2008 the $2.5 million other-than-temporary impairment charge on the Company's auction rate securities), non-cash leasing revenue and non-cash ground lease expense. In addition, Adjusted EBITDA excludes acquisition related costs which are currently capitalized, but, commencing January 1, 2009 pursuant to the adoption of Statement of Financial Accounting Standard 141(R), will be required to be expensed and included within operating expense. 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 revenue minus non-cash leasing revenue. 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. In addition, Adjusted EBITDA is a component of the calculation used by our lenders to determine compliance with our senior credit facility. 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 provisions 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; and

* 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.

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 and short-term restricted cash. 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 and short-term restricted cash 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:

Net Secured Debt and Secured Leverage Ratio

This press release includes disclosures regarding Net Secured Debt and Secured Leverage Ratio. Net Secured Debt is defined as debt minus unsecured debt and cash and cash equivalents and short-term restricted cash. Secured Leverage Ratio is defined as Net Secured 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 and are used by lenders to evaluate potential borrowing capacity. The non-GAAP measurements of Net Secured Debt and Secured Leverage Ratio have certain material limitations. Specifically, these measurements exclude unsecured debt and cash and cash equivalents and short-term restricted cash 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 and because we are obligated to repay our unsecured debt upon its final maturity, these measures may have material limitations. In addition, since a component of our Secured 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 Secured Debt and our Secured Leverage Ratio as only two of several comparative tools, together with GAAP measurements, to assist in the evaluation of our financial condition.

Equity Free Cash Flow and Equity Free Cash Flow Per Share

This press release, including our third quarter 2008 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 cash 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:
