American Tower Corporation and Bharti Airtel Limited Announce Agreement for the sale of Tower Portfolio in Nigeria

Boston, Massachusetts and New Delhi, India – November 24, 2014: American Tower Corporation (American Tower) (NYSE: AMT) and Bharti Airtel Limited (BSE: 532454) today announced that they have entered into a definitive agreement, through Bharti Airtel Limited’s subsidiary company, Bharti Airtel International (Netherlands) BV (Airtel), for the sale of over 4,800 of Airtel’s communications towers in Nigeria. Airtel will be the anchor tenant on the portfolio under a lease with a ten-year initial term.

“We are pleased to announce the launch of our operations in Nigeria while expanding our relationship with Airtel, one of the leading multinational operators in the world,” said Jim Taiclet, Chairman, President and Chief Executive Officer of American Tower. “With the largest population and economy in Africa and relatively underdeveloped wireless infrastructure, we view Nigeria as a tremendous growth opportunity. Further, we expect this investment to support our long-term objective of generating double-digit AFFO per share growth for our stockholders.”

Commenting on the development, Christian de Faria, MD and Chief Executive Officer of Bharti Airtel Africa, said, “Nigeria is the largest mobile market in Africa and a key one for Airtel. This agreement, which is part of our stated philosophy of promoting infrastructure sharing, will provide us with considerable cost efficiencies and at the same time allows us to sharpen our focus on the customer. American Tower has a proven track record in passive infrastructure management and we look forward to benefitting from the best practices from all other countries it operates in."

The agreement will allow Airtel to focus on its core business and customers, enable it to deleverage through debt reduction and will significantly reduce its on-going capital expenditures on passive infrastructure in Nigeria.

American Tower and Airtel expect to close the acquisition during the first half of 2015, subject to customary closing conditions and regulatory approval.
