Acadia Healthcare (ACHC) 8-K Results of Operations and Financial Condition

Exhibit 99.1

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

The following tables set forth the unaudited pro forma condensed combined financial data for Acadia, YFCS, PHC and MeadowWood as a combined company, giving effect to (1) Acadia’s acquisition of YFCS and the related debt and equity financing transactions on April 1, 2011, (2) PHC’s acquisition of MeadowWood and related debt financing transaction on July 1, 2011 and (3) Acadia’s merger with PHC and the related issuance of senior notes on November 1, 2011, as if each had occurred on September 30, 2011 for the unaudited pro forma condensed combined balance sheet and January 1, 2010 for the unaudited pro forma condensed combined statements of operations. Acadia’s condensed consolidated balance sheet as of September 30, 2011 reflects the acquisition of YFCS and related debt and equity transactions and Acadia’s condensed consolidated statement of operations reflects the results of YFCS operations for the period from April 1, 2011 to September 30, 2011. PHC’s condensed consolidated balance sheet as of September 30, 2011 reflects the acquisition of MeadowWood and related debt financing transaction on July 1, 2011.

The fiscal years of Acadia, YFCS and HHC Delaware end December 31 while the fiscal year of PHC ends on June 30. The combined company will use Acadia’s fiscal year ending December 31.

The unaudited pro forma condensed combined balance sheet combines Acadia’s unaudited consolidated balance sheet as of September 30, 2011 with the consolidated balance sheet of PHC and the unaudited condensed consolidated balance sheet of HHC Delaware as of September 30, 2011. The unaudited pro forma condensed combined statement of operations for the nine months ended September 30, 2010 combines Acadia’s unaudited condensed consolidated statement of operations for the nine months ended September 30, 2010 with the unaudited condensed consolidated statement of operations of YFCS for the nine months ended September 30, 2010, the unaudited condensed consolidated statement of operations of HHC Delaware for the nine months ended September 30, 2010 and the unaudited condensed consolidated statement of operations of PHC for the nine months ended September 30, 2010 (which was derived from the audited consolidated statement of operations of PHC for the fiscal year ended June 30, 2010 less the unaudited condensed consolidated statement of operations of PHC for the six months ended December 31, 2009 plus the unaudited condensed consolidated statement of operations of PHC for the three months ended September 30, 2010). The unaudited pro forma condensed combined statement of operations for the nine months ended September 30, 2011 combines Acadia’s unaudited condensed consolidated statement of operations for the nine months ended September 30, 2011 with the unaudited condensed consolidated statement of operations of YFCS, the unaudited condensed consolidated statement of operations of HHC Delaware from January 1, 2011 through the date of the YFCS acquisition (April 1, 2011) and the unaudited condensed consolidated statement of operations of PHC for the nine months ended September 30, 2011 (which was derived from the audited consolidated statement of operations of PHC for the fiscal year ended June 30, 2011 less the unaudited condensed consolidated statement of operations of PHC for the six months ended December 31, 2010 plus the unaudited condensed consolidated statement of operations of PHC for the three months ended September 30, 2011). The unaudited pro forma condensed combined statement of operations for the year ended December 31, 2010 combines Acadia’s audited consolidated statement of operations for the year ended December 31, 2010 with the audited consolidated statement of operations of YFCS for the year ended December 31, 2010, the audited consolidated statement of operations of HHC Delaware for the year ended December 31, 2010 and the unaudited condensed consolidated statement of operations of PHC for the twelve months ended December 31, 2010 (which was derived from the audited consolidated statement of operations of PHC for the fiscal year ended June 30, 2010 less the unaudited condensed consolidated statement of operations of PHC for the six months ended December 31, 2009 plus the unaudited condensed consolidated statement of operations of PHC for the six months ended December 31, 2010).

The unaudited pro forma condensed combined financial data has been prepared using the acquisition method of accounting for business combinations under GAAP. The adjustments necessary to fairly present the unaudited pro forma condensed combined financial data have been made based on available information and in the opinion of management are reasonable. Assumptions underlying the pro forma adjustments are described in the accompanying notes, which should be read in conjunction with this unaudited pro forma condensed combined financial data. The pro forma adjustments are preliminary and revisions to the fair value of assets acquired and liabilities assumed and the financing of the transactions may have a significant impact on the pro forma adjustments. A final valuation of assets acquired and liabilities assumed in the YFCS, MeadowWood and PHC acquisitions has not been completed and the completion of fair value determinations will most likely result in changes in the values assigned to property and equipment and other assets (including intangibles) acquired and liabilities assumed.

The unaudited pro forma condensed combined financial data is for illustrative purposes only and does not purport to represent what our financial position or results of operations actually would have been had the events noted above in fact occurred on the assumed dates or to project our financial position or results of operations for any future date or future period.

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

(Dollars in thousands)

(1) The amounts in this column represent, for Acadia, actual balances as of September 30, 2011 or actual results for the periods presented.

(2) The amounts in this column represent, for YFCS, actual results for the period from January 1, 2010 to September 30, 2010, the period from January 1, 2011 to the April 1, 2011 acquisition date and for the year ended December 31, 2010.

(3) The amounts in this column represent, for PHC, actual balances as of September 30, 2011 or actual results for the periods presented. The condensed consolidated statements of operations of PHC have been reclassified to conform to Acadia’s expense classification policies.

(4) The amounts in this column represent, for MeadowWood, actual results for the periods presented.

(5) Reflects the elimination of equity accounts of PHC.

(6) Reflects the elimination of PHC deferred financing costs in connection with the repayment of debt.

(7) Represents the adjustments to acquired property and equipment and intangible assets based on preliminary estimates of fair value and the adjustment to goodwill derived from the difference in the estimated total consideration transferred by Acadia and the estimated fair value of assets acquired and liabilities assumed by Acadia in the PHC merger, calculated as follows:

Estimated equity consideration(a)	$	44,025
Estimated fair value of vested replacement share-based awards		1,543
Estimated repayment of indebtedness under PHC’s senior credit facility		26,441
Estimated cash consideration to Class B common stockholders		5,000
Estimated total consideration	$	77,009
Cash and cash equivalents	$	3,261
Accounts receivable		12,466
Other current assets		6,779
Property and equipment		14,494
Contract-based and other intangible assets		1,800
Other long-term assets		1,994
Accounts payable		(2,522	)
Accrued salaries and benefits		(2,572	)
Other accrued liabilities		(1,712	)
Deferred tax liability-long term(b)		(183	)
Other long-term liabilities		(900	)
Fair value of assets acquired less liabilities assumed	$	32,905
Estimated goodwill	$	44,104
Less: Historical goodwill		(10,447	)
Goodwill adjustment	$	33,657

^(a)  The estimated fair value of Acadia common shares issuable to PHC stockholders is based on 4,891,667 of Acadia common shares issued to PHC stockholders multiplied by a stock price of $9.00. The equity consideration is reflected as a $49 increase in common stock based on the conversion of each PHC share into one-quarter of a share of Acadia common stock ($0.01 par value) and a $43,976 increase in additional paid-in capital. The total increase in additional paid-in capital of $45,629 also includes the estimated fair value of the vested portion of replacement equity-based awards of $1,543 and the $110 charge resulting from the accelerated vesting of the stock options held by PHC directors.

^(b)  The deferred tax liability of $183 represents the reclassification of PHC’s deferred tax asset of $648 from other assets to other liabilities less acquisition adjustments of $831 related to book and tax basis differences in intangible assets acquired.

The acquired assets and liabilities assumed will be recorded at their relative fair values as of the closing date of the PHC merger. Estimated goodwill is based upon a determination of the fair value of assets acquired and liabilities assumed that is preliminary and subject to revision as the value of total consideration is finalized and additional information related to the fair value of property and equipment and other assets (including intangible assets) acquired and liabilities assumed becomes available. The actual determination of the fair value of assets acquired and liabilities assumed will differ from that assumed in these unaudited pro forma condensed consolidated financial statements and such differences may be material. Qualitative factors comprising goodwill 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 company.

(8) Represents a $719 increase in cash as a result of the PHC merger. The sources and uses of cash in connection with the PHC merger are expected to be as follows:

Sources:
Issuance of $150,000 of 12.875% Senior Notes due 2018 (“Senior Notes”)	$	147,485
Uses:
Cash payment to Acadia stockholders		(74,441	)
Repayment of indebtedness under PHC’s senior credit facility		(26,441	)
Cash portion of PHC merger consideration		(5,000	)
Transaction costs (a)		(40,884	)
Cash adjustment	$	719

^(a)  Costs incurred in connection with the PHC merger and related transactions are estimated to be $16,525 of acquisition-related expenses (including approximately $2,403 of change in control payments due to certain PHC executives), $20,559 to terminate Acadia’s professional services agreement with Waud Capital Partners and $3,800 of debt financing costs associated with the Senior Notes, the Second Amendment to the Senior Secured Credit Facility and a debt commitment letter issued by Jefferies Finance to provide a senior unsecured bridge loan facility of up to $150.0 million in the event that $150.0 million of the Senior Notes were not issued.
