Quanta Services Announces Definitive Agreement to Sell its Fiber Optic

Licensing Operations to Crown Castle for $1 Billion

Enables Further Strategic Focus on Energy Infrastructure Markets

Transaction Monetizes Undervalued Fiber Optic Licensing Operations

HOUSTON – Apr. 30, 2015 – Quanta Services, Inc. (NYSE: PWR) announced today that it has entered into a definitive agreement to sell its fiber optic licensing operations to Crown Castle International Corp. (NYSE: CCI) for approximately $1 billion in cash. The transaction is subject to various regulatory approvals and other customary conditions prior to closing, but is expected to close by the end of this year. Quanta estimates after tax net proceeds from the transaction of approximately $800 million. J.P. Morgan Securities LLC served as exclusive financial advisor to Quanta for the transaction.

“This transaction enables us to enhance our strategic focus on energy infrastructure markets, which we believe will undergo substantial development in the coming years. Further, we believe the attractive market valuations for fiber assets provide us the opportunity to unlock the value of our fiber optic licensing operations. The purchase price represents a 15 times trailing EBITDA multiple, which recognizes the significant value these operations have created as part of Quanta Services,” said Jim O’Neil, president and chief executive officer of Quanta Services. “I would like to thank all of our fiber optic licensing operations employees for their contributions to our organization over the years.”

Quanta believes there is opportunity to create incremental shareholder value by using the proceeds from this transaction to repurchase its common stock, acquire energy infrastructure services companies and/or make other strategic investments. While the company will continue to evaluate all the opportunities it believes could create shareholder value going forward, it expects to use the proceeds for a combination of these purposes. Since January 1, 2014, Quanta has invested approximately $322 million in cash to acquire companies and approximately $275 million in cash to repurchase shares of its common stock.

As the timing of the close of the transaction with Crown Castle is uncertain, Quanta’s financial outlook includes the contribution of our fiber optic licensing operations for the entire year. For the twelve month period ending December 31, 2015, Quanta’s fiber optic licensing operations are estimated to generate approximately $105 million to $110 million in revenue and $0.12 to $0.13 in diluted earnings per share.
