SBA Communications Corporation (SBA) is a leading independent owner and operator of wireless communications towers in the United States. Based in Boca Raton, Florida, SBA is listed on the NASDAQ Global Select Market Composite Index under the symbol SBAC. We generate revenues from two primary businesses; site leasing and site development services. In our site leasing business, we lease antenna space on towers and other structures that SBA owns or manages. The towers we own have either been built by us at the request of a wireless carrier or built or acquired based on our own initiative. We own, operate and or manage towers and building rooftops across the continental United States.
