We are a leading independent owner and operator of wireless communications infrastructure, including tower structures, rooftops, and other structures that support antennas used for wireless communications, which we collectively refer to as "towers" or "sites." Our principal operations are in the United States and its territories. In addition, we own and operate towers in South America, Central America, and Africa. During the year ended December 31, 2025, we sold all of our towers and ended our operations in both the Philippines and Colombia and sold substantially all of our operations in Canada. Our primary business line is our site leasing business, which contributed 97.9% of our total segment operating profit for the year ended December 31, 2025. In our site leasing business, we (1) lease space to wireless service providers and other customers on assets that we own or operate and (2) manage rooftop and tower sites for property owners under various contractual arrangements. As of December 31, 2025, we owned 46,328 towers, a substantial portion of which have been built by us or built by other tower owners or operators who, like us, have built such towers to lease space to multiple wireless service providers. Our other business line is our site development business, through which we assist wireless service providers in developing and maintaining their own wireless service networks.
Our primary strategy is to continue to focus on expanding our site leasing business through organic growth and expansion of our tower portfolio to create shareholder value. We believe that the long-term and repetitive nature of our site leasing business will permit us to maintain a stable, recurring cash flow stream and reduce our exposure to cyclical changes in customer spending which arises in our site development business. We believe that our tower operations are highly scalable. Consequently, we believe that we are able to materially increase our domestic and international tower portfolio without proportionately increasing selling, general, and administrative expenses. Key elements of our strategy include:
Maximizing our Tower Capacity. We generally have constructed or acquired towers that accommodate multiple tenants and a majority of our towers are high-capacity tower structures. Most of our towers have significant capacity available for additional antennas, and we believe that increased use of our towers’ structural capacity can generate additional lease revenue and be achieved at a low incremental cost. We measure the available capacity of our existing sites to support additional tenants by assessing several factors, including tower height, tower type, wind loading, environmental conditions, existing equipment on the tower and zoning and permitting regulations in effect in the jurisdiction where the tower is located. We actively market space on our towers through our internal sales force. As of December 31, 2025, we had an average of 1.8 tenants per site.
Capitalizing on our Scale and Management Experience. We are a large owner, operator, and developer of towers, with substantial capital, human capital, and operating resources. We have been developing towers for wireless service providers in the U.S. since 1989 and have owned and operated towers for ourselves since 1997. We believe our size, experience, capabilities, and resources make us a preferred partner for wireless service providers both in the U.S. and internationally. Our management team has extensive experience in site leasing and site development, with some of the longest tenures in the tower and site development industries. We believe that our industry expertise and strong relationships with wireless service providers will permit us to achieve long-term growth in our site leasing and site development services.
