First Quarter Results

Chris Hunter, Chief Executive Officer of Acadia, remarked, “We are pleased to deliver first quarter results for both revenue and Adjusted EBITDA in line with our respective outlook ranges, with Adjusted EBITDA coming in at the high end of our expectations for the quarter. This year is setting up to be the largest bed expansion year in Acadia’s history, building upon our record-breaking bed additions in 2024.

Footnotes

We have included certain financial measures in this press release, including those listed below, which are “non-GAAP financial measures” as defined under the rules and regulations promulgated by the SEC.  These non-GAAP financial measures include, and are defined, as follows:

• EBITDA:  net income attributable to Acadia Healthcare Company, Inc. adjusted for net income attributable to noncontrolling interests, provision for income taxes, net interest expense and depreciation and amortization.

• Adjusted EBITDA: EBITDA adjusted for equity-based compensation expense, transaction, legal and other costs, debt extinguishment and legal settlements expense.

• Adjusted income before income taxes attributable to Acadia Healthcare Company, Inc.: net income attributable to Acadia Healthcare Company, Inc. adjusted for transaction, legal and other costs, debt extinguishment, legal settlements expense and provision for income taxes.

• Adjusted income attributable to Acadia Healthcare Company, Inc.: Adjusted income before income taxes attributable to Acadia Healthcare Company, Inc. adjusted for the income tax effect of adjustments to income. 

• Total facility adjusted EBITDA: Adjusted EBITDA adjusted for general and administrative costs related to our corporate functions. General and administrative costs directly related to the facilities are included in total facility results.

• Same facility adjusted EBITDA: Adjusted EBITDA for facilities and services to those facilities operated in both the current and prior year. These metrics exclude the operating results associated with facilities under operation for less than one year and facilities acquired, divested or removed from service during the current or prior year.

The non-GAAP financial measures presented herein are supplemental measures of our performance and are not required by, or presented in accordance with, generally accepted accounting principles in the United States (“GAAP”). The non-GAAP financial measures presented herein are not measures of our financial performance under GAAP and should not be considered as alternatives to net income or any other performance measures derived in accordance with GAAP or as an alternative to cash flow from operating activities as measures of our liquidity. Our measurements of these non-GAAP financial measures may not be comparable to similarly titled measures of other companies. We have included information concerning the non-GAAP financial measures in this press release because we believe that such information is used by certain investors as measures of a company’s historical performance. We believe 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 similar non-GAAP financial measures when reporting their results. Because the non-GAAP financial measures are not measurements determined in accordance with GAAP and are thus susceptible to varying calculations, the non-GAAP financial measures, as presented, may not be comparable to other similarly titled measures of other companies. Our presentation of these non-GAAP financial measures should not be construed as an inference that our future results will be unaffected by unusual or nonrecurring items.

Total facility results include operating results for all of our facilities and services but exclude general and administrative costs related to our corporate functions. Such costs related to our corporate functions include, amongst others, costs for accounting and finance, information systems, human resources, legal and operational and executive leadership. General and administrative costs directly related to the facilities are included in facility results. Such costs directly related to our facilities include, amongst others, labor at the facility level, insurance, including property, professional, legal and general liability insurance, hospital supplies, including medication, utilities and food service, and general maintenance costs for the facility. We determine which general and administrative costs to exclude and include in total facility results by ensuring those costs directly associated with facility operations are captured at the facility level for reporting. Note that total facility costs include those related to new facilities and the cost of closure and run-out costs related to facilities we have closed. We believe that providing results on a total facility basis is helpful to our investors as a measure of our financial and operating performance because it neutralizes the impact of corporate-level items that do not arise out of our core operations at our facilities.

Same facility results include operating results only for facilities and services operated in both the current and prior year. These metrics exclude the operating results associated with facilities under operation for less than one year and facilities acquired during the current or prior year, as well as facilities divested or removed from service. We believe that providing results on a same facility basis is helpful to investors because it neutralizes the impact of new facilities that are in early stages of operation and facilities that we no longer operate, each of which may distort investors’ understanding of the Company’s underlying performance at our existing and continuing facilities. Further, we believe that providing same facility information is helpful to our investors as a measure of the financial and operating performance of our existing and continuing facilities on a comparable basis, and same facility results provide investors with information useful in understanding underlying organic growth in such facilities. For these reasons, we believe that same facility results are particularly useful during periods of significant expansion or contraction.

Total facility results reflect adjustments that are intended to provide the specific presentation described above, and same facility results reflect adjustments that may be irregular in timing from period to period related to newly opened or acquired facilities or facilities that we no longer operate, and may omit certain results that investors may view as important. Total facility and same facility results may therefore not be indicative of the overall performance of our business and should be not be considered as alternatives for net income or any other performance measures derived in accordance with GAAP.

The Company is not able to provide a reconciliation of projected Adjusted EBITDA and adjusted earnings per diluted share, where provided, to expected results due to the unknown effect, timing and potential significance of transaction-related expenses and the tax effect of such expenses.

Footnotes (continued)

(a) Represents the equity-based compensation expense of Acadia. Equity-based compensation expense is excluded from Adjusted EBITDA because Acadia believes that the cost of equity awards granted to employees does not contribute to the earnings potentially available for distributions to its equity holders or reinvestment into its business.

(b) Represents transaction, legal, and other costs incurred by Acadia primarily related to the following categories: (1) government investigations; (2) termination and restructuring costs; (3) legal, accounting, and other acquisition-related costs; and (4) management transition costs. Government investigations include legal fees and settlement costs related to certain litigation. Termination and restructuring costs include costs, net of gains, incurred related to the closure and disposition of certain facilities or contract amendments. Legal, accounting and other acquisition-related costs include costs incurred for the development of new facilities ($0.9 million and $0.6 million for the three months ended March 31, 2025 and 2024, respectively); legal and settlement costs incurred related to certain litigation not included in Government Investigations ($(3.0) million and $4.0 million for the three months ended March 31, 2025 and 2024, respectively); and direct costs associated with acquisitions ($0.2 million for the three months ended March 31, 2024). Management transition costs include certain costs associated with the transition of the leadership team, including the design and implementation of the revised organizational structure. Management transition costs incurred with the transition of our Chief Executive Officer beginning in the first quarter of 2022 have concluded. The table below quantifies each of the components of transaction, legal and other costs for the periods presented. Such transaction, legal and other costs are excluded from Adjusted EBITDA because Acadia believes that the nature, size, and number of these costs can vary dramatically from period to period and between Acadia and its peers and can also obscure underlying business trends and make comparisons of long-term performance difficult.

(c) Represents debt extinguishment costs recorded during the first quarter of 2025 in connection with the refinancing of the prior credit facility. Debt extinguishment is excluded from Adjusted EBITDA because Acadia believes that this expense is unrelated to Acadia’s day-to-day business operations and not indicative of Acadia’s ongoing operating results.

(d) Represents legal settlements expense related to costs associated with the Desert Hills litigation. Legal settlements expense is excluded from Adjusted EBITDA because Acadia believes that this expense is unrelated to Acadia’s day-to-day business operations and not indicative of Acadia’s ongoing operating results.

(e) Represents general and administrative costs related to our corporate functions, including, amongst others, costs for accounting and finance, information systems, human resources, legal and operational and executive leadership. We determine which general and administrative costs to exclude and include in total facility results by ensuring those costs directly associated with facility operations are captured at the facility level for reporting. Corporate general and administrative costs are excluded to present Total Facility Adjusted EBITDA because we believe that providing results on a total facility basis is helpful to our investors as a measure of the financial and operating performance of our core operations at our facilities.

(f) Represents the portion of EBITDA for the periods presented attributable to de novos and acquired facilities in operation for less than one year and facilities closed during such period. De novos are newly developed facilities built by Acadia or with a joint venture partner. Such amounts are excluded from Adjusted EBITDA to present Same Facility Adjusted EBITDA because we believe providing same facility information is helpful to our investors as a measure of the financial and operating performance of our existing and continuing facilities on a comparable basis, and same facility results provide investors with information useful in understanding underlying organic growth in such facilities.

(g) Represents the income tax effect of adjustments to income based on tax rates of 24.1% and 22.2% for the three months ended March 31, 2025 and 2024, respectively. We believe excluding the income tax effect of adjustments to income assists investors in understanding the tax provision associated with those adjustments and the effect on net income.
