AAC Holdings to Acquire Residential and Outpatient Facilities in North Mississippi for $35 Million

Purchase will bring full continuum of care to southeast; strengthens AAC’s nationwide network

BRENTWOOD, Tenn. – (May 13, 2015) AAC Holdings, Inc. (NYSE: AAC), through its operating subsidiary, American Addiction Centers, Inc., a national leader in addiction treatment and rehabilitation, and its indirect subsidiary, Oxford Treatment Center, LLC, signed a definitive agreement to acquire The Oxford Centre, Inc. and its affiliates, for $35.0 million in cash, officials announced today.

“We are excited to bring The Oxford Centre into our network of addiction treatment centers and to increase our presence in the southeast region,” said Michael Cartwright, Chairman and Chief Executive Officer of AAC Holdings. “The Oxford Centre offers a proven holistic approach to treating the mind, body and spirit on a campus filled with many outdoor elements and amenities. Through this purchase, we will have the opportunity to reach more clients in Mississippi and surrounding states, as well as serve a growing referral base.”

The Oxford Centre operates a 76-bed residential facility located on a secluded, 110-acre campus in Etta, Miss., which is 65 miles southwest of Memphis, Tenn. In addition to the residential facility, AAC will also acquire the operations associated with three outpatient treatment locations in Oxford, Tupelo and Olive Branch, Miss. The purchase is expected to be completed during the second half of the year and is subject to certain closing conditions, including the receipt of governmental approvals and licenses necessary to operate the business.

The Oxford Centre generated revenue of approximately $12.2 million and adjusted EBITDA of approximately $5.6 million for the year ended December 31, 2014.

Upon completion, this purchase will mark the sixth acquisition for AAC Holdings in 2015. This rapid growth, which follows a successful IPO in October 2014, supports the company’s efforts to create a premium national brand with a network of access points for clients seeking treatment and their families.
