With current projects underway and under contract, we currently anticipate doubling our inpatient bed capacity to 1,166 beds by the end of 2016.”

De Novo Activity and Pipeline

In January 2015, the Company received licensure and began treating patients at its new $2.6 million outpatient center in Las Vegas. The new outpatient center provides step-down capacity for AAC’s Desert Hope residential facility.

In January 2015, the Company added 31 beds, 24 of which were detoxification beds, to its Forterus facility in Temecula, California, increasing capacity at the facility to 107 beds.

In February 2015, AAC purchased a former convent and a total of 96 acres in Ringwood, New Jersey for $6.4 million in cash. Renovation of the existing structure and grounds is anticipated to begin in the summer of 2015 with a targeted opening late in the second half of 2016. We anticipate the renovated facility will be a 150-bed residential treatment facility, and the Company anticipates an additional investment of approximately $18.0 million.

In March 2015, the Company entered into a definitive agreement to acquire the operating assets of Sunrise House Foundation, a non-profit, in-network provider of substance abuse treatment with 110 inpatient beds on the main campus in Lafayette, New Jersey; 30 halfway house beds in Franklin, New Jersey and Plainfield, New Jersey; and 2 outpatient treatment programs in Lafayette, New Jersey and Mountainside, New Jersey. The purchase price is $6.6 million in cash and the assumption of up to $0.5 million of certain liabilities. The Company expects to close on the acquisition in the third quarter of 2015 and plans to invest an additional approximately $5.0 million in renovations of the campus over the 12 months following closing.

In April 2015, the Company closed on the acquisition of an 84-bed hospital near Laguna Beach, California for an aggregate of $13.5 million. AAC will begin renovation of the facility in the second quarter of 2015 and will apply for a license to operate as a Chemical Dependency Recovery Hospital. The Company anticipates it will invest an additional approximately $5.0 million for renovations and construction, which will include the addition of up to 40 beds (bringing the total up to 124 beds) 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 will begin treating clients in the second quarter of 2015. The new outpatient center provides step-down capacity for AAC’s Greenhouse residential facility.

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

The Company expects to complete construction of Riverview, the 164-bed, $18.1 million residential facility in Tampa, Florida, in the second half of 2015.

Acquisition Activity

In February 2015, the Company completed the acquisition of Recovery First, an operator of a 56-bed in-network, inpatient substance abuse treatment facility in the greater Fort Lauderdale, Florida area, for $13.1 million. The Company has commenced an 18-bed expansion of this leased facility for detoxification treatment that is expected to open in the fourth quarter of 2015.

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 restricted shares of the Company’s common stock.

Balance Sheet and Cash Flows from Operations

As of March 31, 2015, AAC Holdings’ balance sheet reflected cash and cash equivalents of $59.2 million and total debt of $76.1 million. Capital expenditures in the first quarter of 2015 totaled $11.5 million. Cash flows used in operations totaled $2.5 million for the first quarter of 2015 compared with cash flows provided by operations of $0.8 million in the prior-year period and $2.2 million in the fourth quarter of 2014. Days sales outstanding (DSO) was 79 for the first quarter of 2015 compared with 80 for the prior-year period and 71 for the fourth quarter of 2014.

During the first quarter, the Company redeemed 100% of the outstanding Series A Preferred units for a total of $8.5 million and repaid in full the $1.0 million of outstanding subordinated promissory notes. The Company also closed on a new five-year, $125.0 million senior secured credit facility led by Bank of America and SunTrust, which consisted of a $50.0 million revolver and a $75.0 million term loan. The facility has an accordion feature that allows the total borrowing capacity to be increased up to $200.0 million.

2015 Outlook

The Company provides the following outlook for 2015, which does not include the impact of Sunrise House Foundation, as well as any future acquisitions and transaction-related costs. Revenues for the full year 2015 are expected to be in a range of $175.0 million to $180.0 million; Adjusted EBITDA is expected to be in a range of $34.0 million to $36.0 million; and Adjusted Earnings per Diluted Share is expected to be in the range of $0.62 to $0.66.

These estimates are based on acquisitions closed to date; utilization of the current 580 inpatient beds to remain in the 85% to 90% range for 2015; average net daily revenue for the inpatient facilities to be in

the mid-to-high $800-range; benefit from our new outpatient center in Las Vegas and a three-quarter benefit from our new outpatient center in Arlington; an economic benefit from the new Tampa facility in the fourth quarter of 2015; the benefit of lab testing from Florida for a full year and from California and Rhode Island for three quarters; an annual effective tax rate of 38% to 40%; and approximately 21.6 million diluted weighted-average shares outstanding.

Reconciliation of Adjusted EBITDA to Net Income

Reconciliation of Adjusted Net Income Available to AAC Holdings, Inc. Common Stockholders to Net Income Available to AAC Holdings, Inc. Common Stockholders

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 and expenses associated with the amendment and restatement of our then-existing credit facility), and acquisition-related 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, reorganization expense, acquisition-related 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 this measure is 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.
