	1. Description of Business and Basis of Presentation
	Description of Business
	Acadia Healthcare Company, Inc. (the “Company”) develops and operates inpatient psychiatric facilities, residential treatment centers, group homes, substance abuse facilities and facilities providing outpatient behavioral healthcare services to serve the behavioral health and recovery needs of communities throughout the United States. At March 31, 2014, the Company operated 52 behavioral healthcare facilities with over 4,300 licensed beds in 24 states and Puerto Rico.
	Basis of Presentation
	The business of the Company is conducted through limited liability companies and C-corporations, each of which is a direct or indirect wholly-owned subsidiary of the Company. The Company’s consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, all of which are 100% owned. All intercompany accounts and transactions have been eliminated in consolidation.
	The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for fair presentation of our financial position and results of operations have been included. The Company’s fiscal year ends on December 31 and interim results are not necessarily indicative of results for a full year or any other interim period. The condensed consolidated balance sheet at December 31, 2013 has been derived from the audited financial statements as of that date. The information contained in these condensed consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements and notes thereto for the fiscal year ended December 31, 2013 included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission on February 21, 2014. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.
	Certain reclassifications have been made to prior years to conform to the current year presentation.

Earnings Per Share	'
	2. Earnings Per Share
	Basic and diluted earnings per share are calculated in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 260, “Earnings Per Share,” based on the weighted-average number of shares outstanding in each period and dilutive stock options, unvested shares and warrants, to the extent such securities have a dilutive effect on earnings per share.
	The following table sets forth the computation of basic and diluted earnings per share for the three months ended March 31, 2014 and 2013 (in thousands except per share amounts):
		Three Months Ended
		March 31,
		2014		2013
	Numerator:
	Basic and diluted earnings per share:
	Income from continuing operations	$	13,021	$	4,054
	Income (loss) from discontinued operations		37		(316	)
	Net income	$	13,058	$	3,738
	Denominator:
	Weighted average shares outstanding for basic earnings per share		50,120		49,911
	Effect of dilutive instruments		366		339
	Shares used in computing diluted earnings per common share		50,486		50,250
	Basic earnings per share:
	Income from continuing operations	$	0.26	$	0.08
	Income (loss) from discontinued operations		—		(0.01	)
	Net income	$	0.26	$	0.07
	Diluted earnings per share:
	Income from continuing operations	$	0.26	$	0.08
	Income (loss) from discontinued operations		—		(0.01	)
	Net income	$	0.26	$	0.07
	Approximately 0.5 million and 0.6 million shares of common stock issuable upon exercise of outstanding stock option awards were excluded from the calculation of diluted earnings per share for the three months ended March 31, 2014 and 2013, respectively, because their effect would have been anti-dilutive.

	3. Acquisitions
	Pacific Grove
	On January 1, 2014, the Company completed its acquisition of the assets of Pacific Grove Hospital (“Pacific Grove”), an inpatient psychiatric facility with 68 licensed beds located in Riverside, California, for cash consideration of $10.5 million.
	2013 Acquisitions
	On December 1, 2013, the Company completed its acquisition of the assets of Cascade Behavioral Hospital (“Cascade”).

On January 31, 2013, the Company completed its acquisition of DMC-Memphis, Inc. d/b/a Delta Medical Center (“Delta”). On January 1, 2013, the Company completed its acquisition of the assets of Greenleaf Center (“Greenleaf”).
	Summary of Acquisitions
	The Company selectively seeks opportunities to expand and diversify its base of operations by acquiring additional facilities. The majority of the goodwill associated with the acquisitions completed in 2014 and 2013 is deductible for federal income tax purposes. The fair values assigned to certain assets and liabilities assumed by the Company have been estimated on a preliminary basis and are subject to change as new facts and circumstances emerge that were present at the date of acquisition. Specifically, the Company is further assessing the valuation of certain tax matters as well as certain receivables and assumed liabilities of Pacific Grove, Cascade, Longleaf, The Refuge and the UMC Facilities. The Company expects to finalize its analyses as the necessary information becomes available to complete the measurement process. Once finalized, the Company will adjust the application of the acquisition method of accounting to reflect its final valuations.
	The preliminary fair values of assets acquired during the three months ended March 31, 2014 in connection with the Pacific Grove acquisition were as follows (in thousands):
	Property and equipment	$	6,500
	Goodwill		3,796
	Intangible assets		204
	Total assets acquired		10,500
	Total liabilities assumed		—
	Net assets acquired	$	10,500
	The fair values of assets acquired and liabilities assumed during 2013, at the corresponding acquisition dates, were as follows (in thousands):
		UMC Facilities		Other		Total
	Cash	$	52	$	873	$	925
	Accounts receivable		5,251		5,868		11,119
	Prepaid expenses and other current assets		722		3,067		3,789
	Property and equipment		22,347		42,672		65,019
	Goodwill		67,268		37,603		104,871
	Intangible assets		1,505		1,910		3,415
	Other assets		4,712		29		4,741
	Total assets acquired		101,857		92,022		193,879
	Accounts payable		1,535		7,487		9,022
	Accrued salaries and benefits		588		3,079		3,667
	Other accrued expenses		315		2,306		2,621
	Other liabilities		—		2,360		2,360
	Total liabilities assumed		2,438		15,232		17,670
	Net assets acquired	$	99,419	$	76,790	$	176,209
	Other
	The qualitative factors comprising the goodwill acquired in the Pacific Grove, Cascade, Longleaf, The Refuge, the UMC Facilities, Delta and Greenleaf acquisitions (collectively the “2013 and 2014 Acquisitions”) include efficiencies derived through synergies expected by the elimination of certain redundant corporate functions and expenses, the ability to leverage call center referrals to a broader provider base, coordination of services provided across the combined network of facilities, achievement of operating efficiencies by benchmarking performance, and applying best practices throughout the combined companies.
	Transaction-related expenses comprised the following costs for the three months ended March 31, 2014 and 2013 (in thousands):
		Three Months Ended
		March 31,
		2014		2013

	Amended and Restated Senior Credit Facility
	The Company entered into the senior secured credit facility, administered by Bank of America, N.A., on April 1, 2011 (“Senior Secured Credit Facility”). The Senior Secured Credit Facility initially included $135.0 million of term loans and a revolving line of credit of $30.0 million.
	On March 1, 2012, the Company amended the Senior Secured Credit Facility to provide an incremental $25.0 million of term loans and increase the revolving line of credit by $45.0 million, from $30.0 million to $75.0 million.
	On December 31, 2012, the Company entered into an Amended and Restated Credit Agreement (the “Amended and Restated Credit Agreement”) which amended and restated the Senior Secured Credit Facility (“Amended and Restated Senior Credit Facility”), to provide a revolving line of credit of $100.0 million and term loans of $300.0 million, which resulted in debt proceeds of $151.1 million.
	On March 11, 2013, the Company entered into a Consent and First Amendment (the “First Amendment”) to the Amended and Restated Credit Agreement. The First Amendment modified the definition of Consolidated EBITDA to permit the add-back for financial covenant purposes of certain fees and expenses related to the partial redemption of the Company’s 12.875% Senior Notes on March 12, 2013. In addition, the First Amendment amended the definitions of Consolidated Leverage Ratio and Consolidated Senior Leverage Ratio to permit the Company to test indebtedness on a basis net of cash and cash equivalents for financial covenant purposes.
	On June 28, 2013, the Company entered into a Second Amendment (the “Second Amendment”) to the Amended and Restated Credit Agreement. The Second Amendment modified certain of the restrictive covenants contained therein to permit the Company to increase the amount of miscellaneous investments it may make, as well as to permit the Company to incur increased amounts of purchase money indebtedness in order to finance certain long-term capital leases.
	On September 30, 2013, the Company entered into a Third Amendment (the “Third Amendment”) to the Amended and Restated Credit Agreement. The Third Amendment modified certain of the restrictive covenants contained therein to permit the incurrence by the Company of increased amounts of miscellaneous types of liens and indebtedness to facilitate its consummation of the acquisition of Longleaf.
	On February 13, 2014, the Company entered into a Fourth Amendment (the “Fourth Amendment”) to the Amended and Restated Credit Agreement, to increase the size of the Amended and Restated Senior Credit Facility and extend the maturity date thereof, which resulted in the Company having a revolving line of credit of up to $300.0 million and term loans of $300.0 million. The Fourth Amendment also reduced the interest rates applicable to the Amended and Restated Senior Credit Facility and provided increased flexibility to the Company in terms of the financial and other restrictive covenants. The Company had $205.6 million of availability under the revolving line of credit as of March 31, 2014. Borrowings under the revolving line of credit are subject to customary conditions precedent to borrowing. The term loans require quarterly principal payments of $1.9 million for March 31, 2014 to December 31, 2014, $3.8 million for March 31, 2015 to December 31, 2015, $5.6 million for March 31, 2016 to December 31, 2016, $7.5 million for March 31, 2017 to December 31, 2017, and $9.4 million for March 31, 2018 to December 31, 2018, with the remaining principal balance due on the maturity date of February 13, 2019. The Fourth Amendment also provides for a $150.0 million incremental credit facility, with the potential for unlimited additional incremental amounts, provided the Company meets certain financial ratios, in each case subject to customary conditions precedent to borrowing.
	Borrowings under the Amended and Restated Senior Credit Facility are guaranteed by each of the Company’s wholly-owned domestic subsidiaries (other than Park Royal and certain other excluded subsidiaries) and are secured by a lien on substantially all of the assets of the Company and its wholly-owned domestic subsidiaries (other than Park Royal and certain other excluded subsidiaries). Borrowings under the Amended and Restated Senior Credit Facility bear interest at a rate tied to the Company’s consolidated leverage ratio (defined as consolidated funded debt to consolidated EBITDA, in each case as defined in the Amended and Restated Credit Agreement). The Applicable Rate (as defined in the Amended and Restated Credit Agreement) for borrowings under the Amended and Restated Senior Credit Facility was 2.75% for Eurodollar Rate Loans (as defined in the Amended and Restated Credit Agreement) and 1.75% for Base Rate Loans (as defined in the Amended and Restated Credit Agreement) at March 31, 2014. Eurodollar Rate Loans bear interest at the Applicable Rate plus the Eurodollar Rate (as defined in the Amended and Restated Credit Agreement) (based upon the British Bankers Association LIBOR Rate (as defined in the Amended and Restated Credit Agreement) prior to commencement of the interest rate period). Base Rate Loans bear interest at the Applicable Rate plus the highest of (i) the federal funds rate plus 0.50%, (ii) the prime rate and (iii) the Eurodollar Rate plus 1.0%. As of March 31, 2014, borrowings under the Amended and Restated Senior Credit Facility bore interest at a rate of 2.75%. In addition, the Company is required to pay a commitment fee on undrawn amounts under the revolving line of credit. The Company paid a commitment fee of 0.50% for undrawn amounts for the period from January 1, 2013 through February 12, 2014 and 0.40% for undrawn amounts for the period from February 13, 2014 through March 31, 2014. The Fourth Amendment resulted in a 0.50% decrease in the Applicable Rate for LIBOR Rate Loans (as defined in the Amended and Restated Credit Agreement) and a 0.10% decrease in the Unused Line Fee (as defined in the Amended and Restated Credit Agreement).
	The Amended and Restated Credit Agreement requires the Company and its subsidiaries to comply with customary affirmative, negative and financial covenants, including a fixed charge coverage ratio, consolidated leverage ratio and senior secured leverage ratio. The Company may be required to pay all of its indebtedness immediately if it defaults on any of the numerous financial or other restrictive covenants contained in any of its material debt agreements. As of March 31, 2014, the Company was in compliance with such covenants.
	12.875% Senior Notes due 2018
	On November 1, 2011, the Company issued $150.0 million of 12.875% Senior Notes due 2018 (the “12.875% Senior Notes”) at 98.323% of the aggregate principal amount of $150.0 million, a discount of $2.5 million. The notes bear interest at a rate of 12.875% per annum. The Company pays interest on the notes semi-annually, in arrears, on November 1 and May 1 of each year.
	The indenture governing the 12.875% Senior Notes contains covenants that, among other things, limit the Company’s ability to: (i) incur or guarantee additional debt or issue certain preferred stock; (ii) pay dividends on the Company’s equity interests or redeem, repurchase or retire the Company’s equity interests or subordinated debt; (iii) transfer or sell assets; (iv) make certain investments; (v) incur certain liens; (vi) restrict the Company’s subsidiaries’ ability to pay dividends or make other payments to the Company; (vii) engage in certain transactions with the Company’s affiliates; and (viii) merge or consolidate with other companies or transfer all or substantially all of the Company’s assets.

The guarantees are full and unconditional and joint and several and the Company, as the parent issuer of the 12.875% Senior Notes, has no independent assets or operations.
	On March 12, 2013, the Company redeemed $52.5 million of the 12.875% Senior Notes using a portion of the net proceeds of its December 2012 equity offering pursuant to the provision in the indenture permitting an optional redemption with equity proceeds of up to 35% of the principal amount of 12.875% Senior Notes. The 12.875% Senior Notes were redeemed at a redemption price of 112.875% of the principal amount thereof plus accrued and unpaid interest to, but not including, the redemption date in accordance with the provisions of the indenture governing the 12.875% Senior Notes. As part of the redemption of 35% of the 12.875% Senior Notes, the Company recorded a debt extinguishment charge of $9.4 million, including the premium and write-off of deferred financing costs, which was recorded in debt extinguishment costs in the consolidated statements of operations.
	6.125% Senior Notes due 2021
	On March 12, 2013, the Company issued $150.0 million of 6.125% Senior Notes due 2021 (the “6.125% Senior Notes”). The 6.125% Senior Notes mature on March 15, 2021 and bear interest at a rate of 6.125% per annum, payable semi-annually in arrears on March 15 and September 15 of each year, beginning on September 15, 2013.
	The indenture governing the 6.125% Senior Notes contains covenants that, among other things, limit the Company’s ability and the ability of its restricted subsidiaries to: (i) pay dividends, redeem stock or make other distributions or investments; (ii) incur additional debt or issue certain preferred stock; (iii) transfer or sell assets; (iv) engage in certain transactions with affiliates; (v) create restrictions on dividends or other payments by the restricted subsidiaries; (vi) merge, consolidate or sell substantially all of the Company’s assets; and (vii) create liens on assets.
	The 6.125% Senior Notes issued by the Company are guaranteed by each of the Company’s subsidiaries that guarantee the Company’s obligations under the Amended and Restated Credit Facility. The guarantees are full and unconditional and joint and several and the Company, as the parent issuer of the 6.125% Senior Notes, has no independent assets or operations.
	The Company may redeem the 6.125% Senior Notes at its option, in whole or part, at any time prior to March 15, 2016, at a price equal to 100% of the principal amount of the 6.125% Senior Notes redeemed, plus accrued and unpaid interest to the redemption date and plus an applicable premium. The Company may redeem the 6.125% Senior Notes, in whole or in part, on or after March 15, 2016, at the redemption prices set forth in the indenture governing the 6.125% Senior Notes plus accrued and unpaid interest to the redemption date. At any time on or before March 15, 2016, the Company may elect to redeem up to 35% of the aggregate principal amount of the 6.125% Senior Notes at a redemption price equal to 106.125% of the principal amount thereof, plus accrued and unpaid interest to the redemption date, with the net proceeds of one or more equity offerings.
	9.0% and 9.5% Revenue Bonds
	On November 11, 2012, in connection with the acquisition of Park Royal, the Company assumed debt of $23.0 million. The fair market value of the debt assumed was $25.6 million and resulted in a debt premium balance being recorded as of the acquisition date. The debt consisted of $7.5 million and $15.5 million of Lee County (Florida) Industrial Development Authority Healthcare Facilities Revenue Bonds, Series 2010 with stated interest rates of 9.0% and 9.5% (“9.0% and 9.5% Revenue Bonds”), respectively. The 9.0% bonds in the amount of $7.5 million have a maturity date of December 1, 2030 and require yearly principal payments beginning in 2013. The 9.5% bonds in the amount of $15.5 million have a maturity date of December 1, 2040 and require yearly principal payments beginning in 2031. The principal payments establish a bond sinking fund to be held with the trustee and shall be sufficient to redeem the principal amounts of the 9.0% and 9.5% Revenue Bonds on their respective maturity dates. As of March 31, 2014 and December 31, 2013, $2.3 million was recorded within other assets on the balance sheet related to the debt service reserve fund requirements. The yearly principal payments, which establish a bond sinking fund, will increase the debt service reserve fund requirements. The bond premium amount of $2.6 million is amortized as a reduction of interest expense over the life of the revenue bonds using the effective interest method.

	Equity Incentive Plans
	The Company issues stock-based awards, including stock options, restricted stock and restricted stock units, to certain officers, employees and non-employee directors under the Acadia Healthcare Company, Inc. Incentive Compensation Plan (the “Equity Incentive Plan”). As of March 31, 2014, a maximum of 4,700,000 shares of the Company’s common stock were authorized for issuance as stock options, restricted stock and restricted stock units or other share-based compensation under the Equity Incentive Plan, of which 2,697,460 were available for future grant. Stock options may be granted for terms of up to ten years. The Company recognizes expense on all share-based awards on a straight-line basis over the requisite service period of the entire award. Grants to employees generally vest in annual increments of 25% each year, commencing one year after the date of grant. The exercise prices of stock options are equal to the most recent closing price of the Company’s common stock on the date of grant.
	The Company recognized $1.8 million and $0.6 million in equity-based compensation expense for the three months ended March 31, 2014 and 2013, respectively. As of March 31, 2014, there was $27.2 million of unrecognized compensation expense related to unvested options, restricted stock and restricted stock units, which is expected to be recognized over the remaining weighted average vesting period of 1.6 years.
	As of March 31, 2014, there were no warrants outstanding and exercisable. The Company recognized a deferred income tax benefit of $0.7 million for the three months ended March 31, 2014 related to equity-based compensation expense. The actual tax benefit realized from stock options exercised during the three months ended March 31, 2014 was $2.7 million. The Company recognized a deferred income tax benefit of $0.2 million for the three months ended March 31, 2013 related to equity-based compensation expense.

	The grant-date fair value of the Company’s stock options is estimated using the Black-Scholes option pricing model. The following table summarizes the grant-date fair value of options and the assumptions used to develop the fair value estimates for options granted during the three months ended March 31, 2014 and year ended December 31, 2013:
		March 31,			December 31,
		2014			2013
	Weighted average grant-date fair value of options	$	18.23		$	11.62
	Risk-free interest rate		1.7	%		1	%
	Expected volatility		36	%		40	%
	Expected life (in years)		5.5			5.5
	The Company’s estimate of expected volatility for stock options is based upon the volatility of guideline companies given the lack of sufficient historical trading experience of the Company’s common stock. The risk-free interest rate is the approximate yield on United States Treasury Strips having a life equal to the expected option life on the date of grant. The expected life is an estimate of the number of years an option will be held before it is exercised.

	Contingent consideration liability	$	7,000	$	6,500	$	7,000	$	6,500
	The Company’s Amended and Restated Senior Credit Facility, 12.875% Senior Notes, 6.125% Senior Notes and 9.0% and 9.5% Revenue Bonds were categorized as Level 2 in the GAAP fair value hierarchy. Fair values were based on trading activity among the Company’s lenders and the average bid and ask price as determined using published rates.
	The fair value of the contingent consideration liability at March 31, 2014 was categorized as Level 3 in the GAAP fair value hierarchy. The contingent consideration liability was valued using a probability-weighted discounted cash flow method. This analysis reflected the contractual terms of the purchase agreements and utilized assumptions with regard to future earnings, probabilities of achieving such future earnings and a discount rate. Significant increases with respect to assumptions as to future earnings and probabilities of achieving such future earnings would result in higher fair value measurement while an increase in the discount rate would result in a lower fair value measurement. During the three months ended March 31, 2014, the Company changed its projections of the timing of future payments. This change resulted in a $0.5 million increase in the fair value of the contingent consideration liability, which was recorded in transaction-related expenses in the consolidated statements of operations.

Description of Business	'
	Description of Business
	Acadia Healthcare Company, Inc. (the “Company”) develops and operates inpatient psychiatric facilities, residential treatment centers, group homes, substance abuse facilities and facilities providing outpatient behavioral healthcare services to serve the behavioral health and recovery needs of communities throughout the United States. At March 31, 2014, the Company operated 52 behavioral healthcare facilities with over 4,300 licensed beds in 24 states and Puerto Rico.
Basis of Presentation	'
	Basis of Presentation
	The business of the Company is conducted through limited liability companies and C-corporations, each of which is a direct or indirect wholly-owned subsidiary of the Company. The Company’s consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, all of which are 100% owned. All intercompany accounts and transactions have been eliminated in consolidation.
	The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for fair presentation of our financial position and results of operations have been included. The Company’s fiscal year ends on December 31 and interim results are not necessarily indicative of results for a full year or any other interim period. The condensed consolidated balance sheet at December 31, 2013 has been derived from the audited financial statements as of that date. The information contained in these condensed consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements and notes thereto for the fiscal year ended December 31, 2013 included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission on February 21, 2014. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.
	Certain reclassifications have been made to prior years to conform to the current year presentation.
Recently Issued Accounting Standards	'
	In April 2014, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity” (“ASU 2014-08”). ASU 2014-08 raises the threshold for a disposal to qualify as a discontinued operation and requires new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. ASU 2014-08 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2014. Early adoption is permitted. Management is evaluating the impact of ASU 2014-08 on the Company’s consolidated financial statements and does not expect ASU 2014-08 to have a significant impact on the Company’s consolidated financial statements.
