Crown Castle Announces Agreement to Acquire NextG Networks
Addition of Largest Provider of Outdoor Distributed Antenna Systems Will Broaden Crown Castle's Wireless Infrastructure Offering

HOUSTON, Dec. 16, 2011 (GLOBE NEWSWIRE) -- Crown Castle International Corp. (NYSE:CCI) announced today that it has entered into a definitive agreement to acquire NextG Networks, Inc. ("NextG") for approximately $1.0 billion in cash (subject to certain adjustments). NextG, the largest provider of outdoor distributed antenna systems ("DAS"), currently has over 7,000 nodes-on-air and a further 1,500 nodes under construction. In addition, NextG has rights to over 4,600 miles of fiber. DAS is a network of antennas connected by fiber to a communications hub designed to facilitate wireless communications services for multiple operators. The acquisition will expand Crown Castle's portfolio of DAS, providing additional wireless coverage and capacity solutions to customers beyond those areas traditionally served by towers. The acquisition is expected to close in the second quarter of 2012. Crown Castle expects to fund the acquisition with debt financing.

"Increasingly, we believe that small-cell architecture, such as DAS, will be an important complement to traditional macro tower installations," said Ben Moreland, Crown Castle's President and Chief Executive Officer.  "We are very pleased with our anticipated acquisition of NextG, which furthers our ability to extend wireless infrastructure beyond those areas traditionally served by towers, thereby broadening our service offering in this growing market and positioning us to benefit from the continued demand for wireless data. We expect the impact to recurring cash flow per share from the contemplated acquisition and related expected debt financing to be approximately neutral at closing. Further, we believe this acquisition increases our growth rates and is accretive to long-term recurring cash flow per share." 

"Our agreement today is testament to the market leadership NextG has achieved over the past few years and to the increasingly critical role small-cell solutions, including DAS, have played and will play in the future to ensure reliable and comprehensive wireless infrastructure," said Steven Moskowitz, NextG's Chief Executive Officer. "I am proud of all that our employees have accomplished. We have significantly expanded our footprint, broadened our customer relationships, improved our network deployment efficiency, and continuously upgraded our technology and customer service. Our technology solution will be additive to Crown Castle's industry-leading offering, and I am confident that NextG and its employees will be strong contributors to Crown Castle's success for many years to come."

Consistent with Crown Castle's focus on the top 100 BTAs in the US, over 90% of NextG nodes are in urban and suburban locations, with 80% in the top ten US metropolitan areas, including New York, Los Angeles, Chicago and Dallas Fort Worth. The NextG assets are expected to provide significant growth, as they currently average only 1.25 tenants per network. Following the contemplated acquisition, Crown Castle expects to be the largest independent DAS operator in the US, with approximately 10,000 nodes and 26 venues in operation or under construction. 

NextG is to be acquired from a group of investors led by Madison Dearborn Partners, a private equity firm. Madison Dearborn, Accel Partners, Redpoint Ventures and Meritech Capital Partners purchased NextG in 2009. NextG is being advised by Deutsche Bank Securities Inc., Kirkland & Ellis LLP and Kelley Drye & Warren LLP. Crown Castle is being advised by Cravath, Swaine & Moore LLP.
