De Novo, Acquisition and Corporate Highlights:

Revenues in the second quarter of 2015 increased to $53.8 million compared with $29.1 million in the prior-year period and $42.8 million in the first quarter of 2015. Net income available to stockholders increased to $5.6 million, or $0.26 per diluted share, in the second quarter of 2015 compared with $0.5 million, or $0.03 per diluted share, in the prior-year period and $2.0 million, or $0.10 per diluted share, in the first quarter of 2015. Adjusted net income available to stockholders increased to $7.1 million, or $0.33 per diluted share, compared with $1.1 million, or $0.07 per diluted share, in the prior-year period and $3.2 million, or $0.15 per diluted share, in the first quarter of 2015. Adjusted EBITDA increased to $14.0 million compared with $4.2 million in the prior-year period and $8.2 million in the first quarter of 2015. Adjusted net income available to stockholders and Adjusted EBITDA are non-GAAP financial measures. A table reconciling both measures to net income is included in this release.

“Operating metrics for the second quarter continued to outpace our expectations with strong inpatient and outpatient census, client admissions and lab volumes leading to a 230% increase in Adjusted EBITDA,” noted Michael Cartwright, Chairman and Chief Executive Officer of AAC Holdings. “On the clinical front, our partnership with the Centerstone Institute to conduct clinical outcome studies is progressing well, and the strong reception from the rollout of an integrated outpatient services offering in Las Vegas and Arlington reinforces our plans for new outpatient centers across the country. We secured and completed several strategic investments in the quarter as well as made progress with our de novo pipeline that not only will diversify our business but also help us increase inbound demand for an inpatient bed count projected to exceed 1,200 beds by the end of 2016.”

De Novo Activity and Pipeline

In April 2015, the Company completed the acquisition of an 84-bed hospital near Laguna Beach, California for an aggregate of $13.5 million. AAC began renovation of the facility in the second quarter of 2015 and has applied for a license to operate the facility as a Chemical Dependency Recovery Hospital. The Company anticipates it will invest an additional approximately $5.0 million for renovations and construction and has targeted completion for the first half of 2016.

In April 2015, the Company received licensure for its new $2.4 million outpatient center in Arlington, Texas and began treating clients in the second quarter of 2015. The new outpatient center provides step-down capacity for AAC’s Greenhouse residential facility.

The Company began performing quantitative and confirmatory lab testing for California and Rhode Island in April 2015. AAC also began an 8,000-square-foot expansion of its lab in Brentwood that it expects to complete in the third quarter of 2015.

The Company expects to begin operations at River Oaks, the 164-bed, $18.1 million residential facility near Tampa, Florida, in the fourth quarter of 2015.

Acquisition Activity

In April 2015, the Company completed the acquisition of Clinical Services of Rhode Island, an operator of three outpatient treatment facilities in Greenville, Portsmouth and South Kingstown, Rhode Island, for $665,000 in cash and 42,460 shares of the Company’s common stock.

Capital expenditures in the second quarter of 2015 totaled $8.5 million (excluding the acquisition of the 84-bed hospital property near Laguna Beach, California). Cash flows provided by operations totaled $9.1 million for the second quarter of 2015 compared with cash flows used by operations of $0.8 million in the prior-year period and cash flows used by operations of $2.5 million in the first quarter of 2015. Days sales outstanding (DSO) was 80 for the second quarter of 2015 compared with 83 for the prior-year period and 79 for the first quarter of 2015.

2015 Outlook

Based on the second quarter performance and its outlook for the second half of the year, the Company is increasing its guidance for 2015. This outlook does not include the impact of Sunrise House Foundation, The Oxford Centre, or any future acquisitions, transaction-related costs, and expenses related to legal defenses in California. Revenues for the full year 2015 are expected to be in the range of $185 million to $195 million; Adjusted EBITDA is expected to be in the range of $40 million to $42 million; and Adjusted Earnings per Diluted Share is expected to be in the range of $0.75 to $0.80.

These estimates are based on acquisitions closed to date; utilization of the current 587 inpatient beds to remain in the 85% to 90% range for 2015; average daily residential revenue to be in the low-to-mid $900-range; benefit from our new outpatient centers; an economic benefit from the new River Oaks facility in the fourth quarter of 2015; an annual effective tax rate of 38% to 40%; and approximately 21.8 million diluted weighted-average shares outstanding.

Reconciliation of Adjusted EBITDA to Net Income

Adjusted EBITDA, adjusted net income available to AAC Holdings, Inc. common stockholders, and adjusted diluted earnings per share (herein collectively referred to as “Non-GAAP Disclosures”) are “non-GAAP financial measures” as defined under the rules and regulations promulgated by the U.S. Securities and Exchange Commission.

Management defines Adjusted EBITDA as net income adjusted for interest expense, depreciation and amortization expense, income tax expense, stock-based compensation and related tax reimbursements, litigation settlement, reorganization expense (which includes certain reorganization transactions completed in April 2014 (the “Reorganization Transactions”) and expenses associated with the amendment and restatement of our prior credit facility in April 2014), acquisition-related expense and de novo start-up expense. Where applicable, these include professional services for accounting, legal, valuation services and licensing expenses.

Management defines Adjusted Net Income Available to AAC Holdings, Inc. common stockholders as net income available to AAC Holdings, Inc. common stockholders adjusted for the redemption of BHR Series A Preferred Units, litigation settlement, reorganization expense (which includes the Reorganization Transactions and expenses associated with the amendment and restatement of our prior credit facility in April 2014), acquisition-related expense and de novo start-up expense and the income tax effect of the non-GAAP adjustments at the then applicable effective tax rate.

The Non-GAAP Disclosures are considered supplemental measures of the Company’s performance and are not required by, or presented in accordance with, generally accepted accounting principles, or GAAP. The Non-GAAP Disclosures are not measures of the Company’s financial performance under GAAP and should not be considered as an alternative to net income or any other performance measures derived in accordance with GAAP. Management has included information concerning Non-GAAP Disclosures because they believe that such information is used by certain investors as a measure of a company’s historical performance. Management believes these measures are frequently used by securities analysts, investors and other interested parties in the evaluation of issuers of equity securities, many of which present EBITDA and Adjusted EBITDA when reporting their results. Because Non-GAAP Disclosures are not determined in accordance with GAAP, they are subject to varying calculations and may not be comparable to similarly titled measures of other companies. Management’s presentation of Non-GAAP Disclosures should not be construed as an inference that our future results will be unaffected by unusual or nonrecurring items.
