(Unaudited)

1.
Description of Business and Basis of Presentation

Description of Business

Unless the context otherwise requires, all references herein to “Acadia,” “the Company,” “we,” “us” or “our” mean Acadia Healthcare Company, Inc. and its consolidated subsidiaries. Acadia Healthcare Company, Inc. is a holding company whose direct and indirect subsidiaries own and operate acute inpatient psychiatric facilities, specialty treatment facilities, comprehensive treatment centers (“CTCs”), residential treatment centers and facilities providing outpatient behavioral healthcare services to serve the behavioral healthcare and recovery needs of communities throughout the United States (the “U.S.”) and Puerto Rico. At September 30, 2025, these subsidiaries operated 278 behavioral healthcare facilities with approximately 12,500 beds in 40 states and Puerto Rico. The terms “facilities,” “centers,” “clinics,” and “hospitals” refer to entities owned, operated, or managed by subsidiaries of Acadia Healthcare Company, Inc. References herein to “employees” refer to employees of subsidiaries of Acadia Healthcare Company, Inc.

Basis of Presentation

The business of the Company is conducted through limited liability companies, partnerships and C-corporations. The Company’s condensed consolidated financial statements include the accounts of the Company and all subsidiaries controlled by the Company through its direct or indirect ownership of majority interests and exclusive rights granted to the Company as the controlling member of an entity. All intercompany accounts and transactions have been eliminated in consolidation.

The accompanying condensed 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 the Company’s 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, 2024 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, 2024 included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (the “SEC”) on February 27, 2025. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

Certain reclassifications have been made to the prior year to conform to the current year presentation.

Recently Issued Accounting Standards

In August 2023, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2023-05 Business Combinations—Joint Venture Formations (Subtopic 805-60) (“ASU 2023-05”) “Recognition and Initial Measurement”. ASU 2023-05 requires entities to recognize and initially measure a joint venture's assets and liabilities at fair value on the formation date. This guidance is effective prospectively for all joint ventures formed on or after January 1, 2025 and may be applied either prospectively or retrospectively. The Company prospectively adopted ASU 2023-05 on January 1, 2025, and such adoption did no t have a significant impact on the Company’s condensed consolidated financial statements.

In November 2023, the FASB issued ASU 2023-07 Segment Reporting (Topic 280) (“ASU 2023-07”) “Improvements to Reportable Segment Disclosures”. ASU 2023-07 is intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The guidance in ASU 2023-07 regarding interim disclosures is effective for interim periods within fiscal years beginning after December 15, 2024. The Company adopted the interim disclosure requirements in ASU 2023-07 on January 1, 2025, and such adoption did no t have a significant impact on the Company’s condensed consolidated financial statements. See Note 19 — Segments for additional information on the Company’s accounting for segment reporting.

In December 2023, the FASB issued ASU 2023-09 Income Taxes (Topic 740) (“ASU 2023-09”) “Improvements to Income Tax Disclosures”. ASU 2023-09 is intended to enhance the transparency and decision usefulness of annual income tax disclosures. This guidance is effective for fiscal years beginning after December 15, 2024 and may be applied either prospectively or retrospectively. The Company is currently evaluating the impact of ASU 2023-09 on the Company’s condensed consolidated financial statements.

In November 2024, the FASB issued ASU 2024-03 Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40) (“ASU 2024-03”) “Disaggregation of Income Statement Expenses”. ASU 2024-03 requires disaggregated disclosure of certain income statement expenses. This guidance is effective for fiscal years beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted and must be applied prospectively. The Company is currently evaluating the impact of ASU 2024-03 on the Company’s condensed consolidated financial statements.

In July 2025, the FASB issued ASU 2025-05 Financial Instruments—Credit Losses (Topic 326) (“ASU 2025-05”) “Measurement of Credit losses for Accounts Receivable and Contract Assets”. ASU 2025-05 allows entities to elect a practical expedient to assume the current conditions as of the balance sheet date remain unchanged for the remaining life of the asset in the development of a reasonable and supportable forecast for current accounts receivable and current contract assets arising from transactions accounted for under Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers. This guidance is effective for fiscal years beginning after December 15, 2025, and interim reporting periods within those fiscal years, and must be adopted prospectively. Early adoption is permitted and must be applied as of the beginning of the annual reporting period in which it is early adopted. The Company is currently evaluating the impact of ASU 2025-05 on the Company’s condensed consolidated financial statements.

In September 2025, the FASB issued ASU 2025-06 Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40) (“ASU 2025-06”) “Targeted Improvements to the Accounting for Internal-Use Software”. ASU 2025-06 is intended to clarify and modernize the accounting for costs related to internal-use software. This guidance is effective for fiscal years beginning after December 15, 2027, and interim periods within those fiscal years, and may be adopted using a prospective, retrospective, or modified transition approach. Early adoption is permitted and must be applied as of the beginning of the annual reporting period in which it is early adopted. The Company is currently evaluating the impact of ASU 2025-06 on the Company’s condensed consolidated financial statements.

Revenue

Revenue is primarily derived from services rendered to patients for inpatient psychiatric and substance abuse care, outpatient psychiatric care and residential treatment. The services provided by the Company have no fixed duration and can be terminated by the patient or the facility at any time, and therefore, each treatment is its own stand-alone contract.

Services ordered by a healthcare provider in an episode of care are not separately identifiable and therefore have been combined into a single performance obligation for each contract. The Company recognizes revenue as its performance obligations are completed. The performance obligation is satisfied over time as the customer simultaneously receives and consumes the benefits of the healthcare services provided. For inpatient services, the Company recognizes revenue equally over the patient stay on a daily basis. For outpatient services, the Company recognizes revenue equally over the number of treatments provided in a single episode of care. Typically, patients and third-party payors are billed within several days of the service being performed or the patient being discharged, and payments are due based on contract terms.

As the Company’s performance obligations relate to contracts with a duration of one year or less, the Company elected the optional exemption in ASC 606-10-50-14(a). Therefore, the Company is not required to disclose the transaction price for the remaining performance obligations at the end of the reporting period or when the Company expects to recognize the revenue. The Company has minimal unsatisfied performance obligations at the end of the reporting period as its patients typically are under no obligation to remain admitted in the Company’s facilities.

The Company disaggregates revenue from contracts with customers by service type and by payor.

The Company’s facilities and services provided by the facilities can generally be classified into the following categories: acute inpatient psychiatric facilities; specialty treatment facilities; CTCs; and residential treatment centers.

Acute inpatient psychiatric facilities. Acute inpatient psychiatric facilities provide a high level of care in order to stabilize patients that are either a threat to themselves or to others. The acute setting provides 24-hour observation, daily intervention and monitoring by psychiatrists.

Specialty treatment facilities. Specialty treatment facilities include residential recovery facilities and eating disorder facilities. The Company provides a comprehensive continuum of care for adults with addictive disorders and co-occurring mental disorders. Inpatient, including detoxification and rehabilitation, partial hospitalization and outpatient treatment programs give patients access to the least restrictive level of care.

Comprehensive treatment centers. CTCs specialize in providing medication-assisted treatment in an outpatient setting to
individuals addicted to opioids such as opioid analgesics (prescription pain medications).

6

Residential treatment centers. Residential treatment centers treat patients with behavioral disorders in a non-hospital setting. The facilities balance therapy activities with social, academic and other activities.

The table below presents total revenue attributed to each category (in thousands):

|  | Three Months Ended September 30, |  |  | Nine Months Ended September 30, |
|  | 2025 |  |  | 2024 |  |  | 2025 |  |  | 2024 |
Acute inpatient psychiatric facilities |  | $ | 471,455 |  |  | $ | 439,788 |  |  | $ | 1,379,088 |  |  | $ | 1,269,593 |
Specialty treatment facilities |  |  | 148,153 |  |  |  | 155,787 |  |  |  | 430,882 |  |  |  | 450,668 |
Comprehensive treatment centers |  |  | 144,506 |  |  |  | 134,174 |  |  |  | 423,013 |  |  |  | 400,984 |
Residential treatment centers |  |  | 87,459 |  |  |  | 85,885 |  |  |  | 258,327 |  |  |  | 258,480 |
Revenue |  | $ | 851,573 |  |  | $ | 815,634 |  |  | $ | 2,491,310 |  |  | $ | 2,379,725 |

The Company receives payments from the following sources for services rendered in its facilities: (i) state governments under their respective Medicaid and other programs; (ii) commercial insurers; (iii) the federal government under the Medicare program administered by the Centers for Medicare and Medicaid Services (“CMS”) and other programs; and (iv) individual patients and clients. The recognition of revenue under certain state government programs can depend on the timing of the programs’ approval by regulatory authorities. Based on the timing of approval of one such program, during the nine months ended September 30, 2025, the Company recognized $65.6 million of revenue, $34.4 million of which related to services rendered in the year ended December 31, 2024.

The Company determines the transaction price based on established billing rates reduced by contractual adjustments provided to third-party payors, discounts provided to uninsured patients and implicit price concessions. Contractual adjustments and discounts are based on contractual agreements, discount policies and historical experience. Implicit price concessions are based on historical collection experience. Most of the Company’s facilities have contracts containing variable consideration. However, it is unlikely a significant reversal of revenue will occur when the uncertainty is resolved, and therefore, the Company has included the variable consideration in the estimated transaction price. Subsequent changes resulting from a patient’s ability to pay are recorded as bad debt expense, which is included as a component of other operating expenses in the condensed consolidated statements of income. Bad debt expense for the three and nine months ended September 30, 2025 and 2024 was not significant.

The following table presents the Company’s revenue by payor type and as a percentage of revenue (in thousands):

|  | Three Months Ended September 30, |  |  | Nine Months Ended September 30, |
|  | 2025 |  |  | 2024 |  |  | 2025 |  |  | 2024 |

4. Earnings Per Share

The following table sets forth the computation of basic and diluted earnings per share for the three and nine months ended September 30, 2025 and 2024 (in thousands, except per share amounts):

|  | Three Months Ended September 30, |  |  | Nine Months Ended September 30, |
|  | 2025 |  |  | 2024 |  |  | 2025 |  |  | 2024 |
Numerator: |  |  |  |  |  |  |  |  |  |  |  |
Net income attributable to Acadia Healthcare Company, Inc. |  | $ | 36,246 |  |  | $ | 68,132 |  |  | $ | 74,747 |  |  | $ | 222,997 |
Denominator: |  |  |  |  |  |  |  |  |  |  |  |
Weighted average shares outstanding for basic earnings per share |  |  | 90,414 |  |  |  | 91,720 |  |  |  | 90,794 |  |  |  | 91,571 |
Effects of dilutive instruments |  |  | 170 |  |  |  | 468 |  |  |  | 461 |  |  |  | 548 |

Earnings per share attributable to Acadia Healthcare Company, Inc. stockholders: |  |  |  |  |  |  |  |  |  |  |  |
Basic |  | $ | 0.40 |  |  | $ | 0.74 |  |  | $ | 0.82 |  |  | $ | 2.44 |
Diluted |  | $ | 0.40 |  |  | $ | 0.74 |  |  | $ | 0.82 |  |  | $ | 2.42 |

Approximately 2.0 million and 0.3 million shares of common stock issuable upon exercise of certain outstanding stock option awards were excluded from the calculation of diluted earnings per share for the three months ended September 30, 2025 and 2024, respectively, because their effect would have been anti-dilutive. Approximately 1.2 million and 0.3 million shares of common stock issuable upon exercise of certain outstanding stock option awards were excluded from the calculation of diluted earnings per share for the nine months ended September 30, 2025 and 2024, respectively, because their effect would have been anti-dilutive.

Commitments and Contingencies

Professional and General Liability

The Company is subject to medical malpractice and other lawsuits due to the nature of the services the Company provides. A portion of the Company’s professional liability risks are insured through a wholly-owned insurance subsidiary providing coverage for up to $10.0 million per claim, $15.0 million for certain other claims and $25.0 million for certain batched claims through August 31, 2025 and $15.0 million per claim and $25.0 million for certain batched claims thereafter. The Company has obtained reinsurance coverage from a third-party to cover claims in excess of those limits. The reinsurance policy has a coverage limit of $80.0 million or $75.0 million in the aggregate for certain other claims through August 31, 2025 and $75.0 million in the aggregate for claims thereafter. The Company’s reinsurance receivables are recognized consistent with the related liabilities and include known claims and any incurred but not reported claims that are covered by current insurance policies in place.

Legal Proceedings

The Company is, from time to time, subject to various claims, lawsuits, governmental investigations and regulatory actions, including claims for damages for personal injuries, medical malpractice, overpayments, breach of contract, securities law violations, and tort and employment related claims. In these actions, plaintiffs request a variety of damages, including, in some instances, punitive and other types of damages that may not be covered by insurance. In addition, healthcare companies are subject to numerous investigations by various governmental agencies. Certain of the Company’s individual facilities have received, and from time to time, other facilities may receive, subpoenas, civil investigative demands, audit requests and other inquiries from, and may be subject to investigation by, federal and state agencies. These investigations can result in repayment obligations, and violations of the federal False Claims Act can result in substantial monetary penalties and fines, the imposition of a corporate integrity agreement and exclusion from participation in governmental health programs. In addition, the False Claims Act permits private parties to bring qui tam, or “whistleblower,” suits against companies that submit false claims for payments to, or improperly retain overpayments from, the government. Some states have adopted similar state whistleblower and false claims provisions.

Desert Hills

From October 2018 to August 2020, the Company, its subsidiary Youth and Family Centered Services of New Mexico, Inc. (“Desert Hills”), and FamilyWorks, a not-for-profit treatment foster care program to which Desert Hills provided management services, including day-to-day administration of the program, via a management services agreement, were among a number of defendants named in five lawsuits (collectively, the “Desert Hills Litigation”) filed in New Mexico State District Court (the “District Court”). These lawsuits each related to abuse by a foster parent, Clarence Garcia, that occurred in foster homes where FamilyWorks had placed children. In 2021, the Company finalized out-of-court settlements for two of the five cases for amounts covered under the Company’s professional liability insurance: Dorsey, as Guardian ad Litem of M.R. v. Clarence Garcia, et al. (the “M.R. case”), and Higgins, as Guardian ad Litem of J.H. v. Clarence Garcia, et al (the “J.H. case”). While the plaintiffs in those two cases had claims pending against FamilyWorks, and FamilyWorks had raised claims or potential claims against the Company, the parties in each of those cases finalized settlements that resolved all claims between FamilyWorks and the Company. The District Court approved the settlement in the J.H. case on June 10, 2024 and the settlement in the M.R. case on August 12, 2024.

On July 7, 2023, in connection with one of the lawsuits in the Desert Hills Litigation styled Inman v. Garcia, et al., Case No. D-117-CV-2019-00136 (the “Inman Litigation”), a jury awarded the plaintiff compensatory damages of $80.0 million and punitive damages of $405.0 million. This award far exceeded the Company’s reasonable expectation based on the previously resolved complaints and far exceeded any precedent for comparable cases.

On October 30, 2023, the Company and Desert Hills entered into settlement agreements in connection with the Inman Litigation, as well as two other related cases – Rael v. Garcia, et al., Case No. D-117-CV-2019-00135 and Endicott-Quinones v. Garcia, et al., Case No. D-117-CV-2019-00137 (together with the Inman Litigation, the “Cases”).

The settlement agreements for the Cases were approved by the District Court in December 2023 and fully resolve each of the Cases with no admission of liability or wrongdoing by either the Company or Desert Hills. On January 19, 2024, pursuant to the terms of the settlement agreements, the Company paid an aggregate amount of $400.0 million in exchange for the release and discharge of all claims arising from, relating to, concerning or with respect to all harm, injuries or damages asserted in the Cases or that may be asserted in the future by the plaintiffs in the Cases.

On January 30, 2024, a sixth lawsuit styled CNRAG, Inc. as Legal Guardian of A.C. v. Garcia et al., No. D-117-CV-2024-00045 was filed in the District Court alleging similar claims as the previous five lawsuits in the Desert Hills Litigation. The ward in this sixth lawsuit was referenced in prior criminal charges against Garcia in January 2019; however, prior to this lawsuit, neither the ward nor guardian made contact with the Company about a possible claim. The Company determined that a lawsuit from this plaintiff was unlikely because no claims had ever been asserted and the statute of limitations had expired. Plaintiff’s allegations assert certain claims, which, if true, may toll the statute of limitations. At this time, the Company is not able to reasonably estimate the amount or

10

range of the ultimate liability, if any, in connection with this sixth lawsuit. No additional victims are referenced in the prior criminal charges against Garcia.

Securities Litigation

On April 1, 2019, a consolidated complaint was filed against the Company and certain former and current officers in the lawsuit styled St. Clair County Employees’ Retirement System v. Acadia Healthcare Company, Inc., et al., Case No. 3:19-cv-00988, which is pending in the United States District Court for the Middle District of Tennessee. The complaint is brought on behalf of a class consisting of all persons (other than defendants) who purchased securities of the Company between April 30, 2014 and November 15, 2018, and alleges that defendants violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 (the “Exchange Act”) and Rule 10b-5 promulgated thereunder. On September 30, 2022, the court entered an order certifying a class consisting of all persons who purchased or otherwise acquired the common stock of the Company between April 30, 2014 and November 15, 2018. On October 16, 2025, the court denied defendants’ motion for summary judgment, which decision defendants have asked the court to certify for interlocutory appeal and to stay case proceedings while the appeal is pending. The case is set for trial on November 18, 2025, if a stay is not granted. Plaintiffs are seeking damages ranging from $5.48 to $16.84 per share for shares that are part of the class.

On July 10, 2025, a consolidated class action complaint was filed against the Company and certain former and current officers in the consolidated lawsuit styled Kachrodia v. Acadia Healthcare Company, Inc., et al., Case No. 3:24-cv-01238, which is pending in the United States District Court for the Middle District of Tennessee. The complaint is brought on behalf of a putative class consisting of all persons (other than defendants) who purchased or otherwise acquired publicly traded securities of the Company between February 8, 2020 and February 27, 2025. The complaint alleges that defendants violated Sections 10(b) and 20(a) of the Exchange Act and Rule 10b-5 promulgated thereunder. Defendants filed a motion to dismiss the consolidated complaint on September 8, 2025. Plaintiffs’ responsive brief is due by November 7, 2025. Defendants’ reply is due by December 22, 2025.

At this time, the Company is not able to reasonably estimate the amount or range of the ultimate liability, if any, in connection with these cases.

Derivative Actions

On February 21, 2019, a purported stockholder filed a related derivative action on behalf of the Company against certain former and current officers and directors in the lawsuit styled Davydov v. Jacobs, et al., Case No. 3:19-cv-00167, which is pending in the United States District Court for the Middle District of Tennessee. The complaint alleges claims for violations of Section 10(b) and 14(a) of the Exchange Act, breach of fiduciary duty, waste of corporate assets, and unjust enrichment. On May 23, 2019, a purported stockholder filed a second related derivative action on behalf of the Company against certain former and current officers and directors in the lawsuit styled Beard v. Jacobs, et al., Case No. 3:19-cv-0441, which is pending the United States District Court for the Middle District of Tennessee. The complaint alleges claims for violations of Sections 10(b), 14(a), and 21D of the Exchange Act, breach of fiduciary duty, waste of corporate assets, unjust enrichment, and insider selling. On June 11, 2019, the Davydov and Beard actions were consolidated. On February 22, 2021, the court entered an order staying the case. On October 23, 2020, a purported stockholder filed a third related derivative action on behalf of the Company against former and current officers and directors in the lawsuit styled Pfenning v. Jacobs, et al., Case No. 2020-0915-NAC, which is pending in the Court of Chancery of the State of Delaware. The complaint alleges claims for breach of fiduciary duty. On February 17, 2021, the court entered an order staying the case. On February 24, 2021, a purported stockholder filed a fourth derivative action on behalf of the Company against former and current officers and directors in the lawsuit styled Solak v. Jacobs, et al., Case No. 2021-0163-NAC, which is pending in the Court of Chancery of the State of Delaware. The complaint alleges claims for breach of fiduciary duty, unjust enrichment, waste of corporate assets, and insider selling. The denial of summary judgment in the securities litigation noted above means that the stays will be lifted in these derivative cases pursuant to the terms of the stay.

On February 14, 2025, a purported stockholder filed a related derivative action on behalf of the Company against certain former and current officers and directors in the lawsuit styled Kachrodia v. Osteen, et al., Case No. 3:25-cv-00172, which is pending in the United States District Court for the Middle District of Tennessee. The complaint alleges claims for violations of Section 10(b) and 21D of the Exchange Act, breach of fiduciary duty, insider selling, unjust enrichment, and waste of corporate assets.

At this time, the Company is not able to reasonably estimate the amount or range of the ultimate liability, if any, in connection with these derivative actions.

Government Investigations

In the fall of 2017, the Office of Inspector General of the U.S. Department of Health and Human Services (the “OIG”) issued subpoenas to three of the Company’s facilities requesting certain documents from January 2013 to the date of the subpoenas. The U.S. Attorney’s Office for the Middle District of Florida issued a civil investigative demand to one of the Company’s facilities in December 2017 requesting certain documents from November 2012 to the date of the demand. In April 2019, the OIG issued subpoenas relating to six additional facilities requesting certain documents and information from January 2013 to the date of the

11

subpoenas. In June 2023, the State of Nevada issued a subpoena relating to one of the same facilities as part of the same investigation. The government’s investigation of each of these facilities (collectively, the “2017 OIG/DOJ Investigation”) focused on claims not eligible for payment because of alleged violations of certain regulatory requirements relating to, among other things, medical necessity, admission eligibility, discharge decisions, length of stay and patient care issues. On September 23, 2024, the Company entered into a civil settlement agreement with the federal government (the “2017 OIG/DOJ Settlement Agreement”), which fully resolved the 2017 OIG/DOJ Investigation with no admission of liability or wrongdoing by the Company. During the year ended December 31, 2024, pursuant to the 2017 OIG/DOJ Settlement Agreement, the Company paid $19.9 million, plus interest, to the federal government and four states that participated in the 2017 OIG/DOJ Investigation in exchange for the release and discharge of any civil or administrative monetary claims arising from the 2017 OIG/DOJ Investigation.

In September 2024, the Company received a grand jury subpoena from the United States District Court for the Western District of Missouri (the “W.D.Mo.”), issued by attorneys from the Criminal Division of the U.S. Department of Justice (the “DOJ Criminal Division”), related to the Company’s acute care service line and related admissions, length of stay and billing practices. In addition, Lakeland Hospital Acquisition, LLC, a subsidiary of the Company, also received a grand jury subpoena from the W.D.Mo. on the same day regarding similar subject matter. The Company had also received requests in September 2024 for information on similar subject matter from the United States Attorney’s Office for the Southern District of New York, which were withdrawn in the same month. The investigation is being led by attorneys from the DOJ Criminal Division. The DOJ Criminal Division withdrew its subpoenas in October 2024, then re-issued subpoenas regarding the same subject matter in December 2024. The DOJ Criminal Division is leading and coordinating the efforts from a number of federal agencies and departments investigating such issues, any of which might later make their own requests for information. The Company has also received subpoenas from the SEC requesting similar information as well as information relating to the CTC service line. The Company is currently conducting a comprehensive internal investigation using external advisors, but, at this time, no findings or conclusions have been made. The Company is fully cooperating with authorities, including active engagement with the DOJ Criminal Division and the SEC. At this time, the Company cannot speculate on whether the outcome of these investigations will have any impact on its business or operations and cannot reasonably estimate the amount or range of the ultimate liability, if any, in connection with these investigations.

Certain members of the United States Congress have requested, and such members or other members may in the future request, information from or about the Company related to, among other things, the Company’s admissions, length of stay, billing practices, and opioid treatment programs. The Company intends to cooperate with any such request. At this time, the Company cannot speculate on the outcome or duration of any such inquiries.

Credit Facility

On February 28, 2025 (the “Credit Facility Closing Date”), the Company entered into a new credit agreement (the “Credit Agreement”), which provides for a $1.0 billion senior secured revolving credit facility (including a $50.0 million sublimit for the issuance of letters of credit and a $50.0 million swingline subfacility) (the “Revolving Facility”) and a $650.0 million senior secured term loan facility (the “Term Loan Facility,” and, together with the Revolving Facility, the “Credit Facility”), each maturing on February 28, 2030.

On the Credit Facility Closing Date, the full $650.0 million amount of the Term Loan Facility was funded, and $550.0 million was funded under the Revolving Facility, which amounts were used, among other things, to refinance the outstanding obligations under the Prior Credit Facility (as defined below).

Borrowings under the Credit Agreement bear interest at a floating rate equal to, at the Company’s option, either (i) a Secured Overnight Financing Rate (“SOFR”) -based rate plus a margin ranging from 1.375% to 2.250% or (ii) a base rate plus a margin ranging from 0.375% to 1.250%, in each case, depending on the Company’s Consolidated Total Net Leverage Ratio (as defined in the Credit Agreement). In addition, an unused fee that varies according to the Company’s Consolidated Total Net Leverage Ratio ranging from 0.200% to 0.350% is payable quarterly in arrears based on the average daily undrawn portion of the commitments in respect of the Revolving Facility. The Term Loan Facility requires quarterly principal repayments of $4.0 million through March 31, 2026, $8.1 million from June 30, 2026 to March 31, 2028, $12.2 million from June 30, 2028 to March 31, 2029 and $16.2 million from June 30, 2029 to December 31, 2029, with the remaining outstanding principal balance of the Term Loan Facility due on the maturity date of February 28, 2030.

The Company has the ability to increase the amount of the Credit Facility, which may take the form of increases to the Revolving Facility or the Term Loan Facility or the issuance of one or more incremental term loan facilities (collectively, the “Incremental Facilities”), upon obtaining additional commitments from new or existing lenders and the satisfaction of certain customary conditions precedent for such Incremental Facilities. Such Incremental Facilities may not exceed the sum of (i) the greater of $710.0 million and an amount equal to 100% of the LTM Consolidated EBITDA (as defined in the Credit Agreement) of the Company at the time of determination and (ii) additional amounts that would not cause the Company’s Consolidated Senior Secured Net Leverage Ratio (as defined in the Credit Agreement) to exceed 4.0 to 1.0.

Subject to certain exceptions, substantially all of the Company’s existing and subsequently acquired or organized direct and indirect wholly-owned U.S. subsidiaries are required to guarantee the repayment of the Company’s obligations under the Credit Agreement. The obligations of the Company and such guarantor subsidiaries are secured by a pledge of substantially all assets of the Company and such guarantor subsidiaries (excluding all real property and certain other customarily excluded assets).

The Credit Agreement contains customary representations and warranties and affirmative and negative covenants, including limitations on the ability of the Company and its subsidiaries to: (i) incur debt; (ii) permit additional liens; (iii) make investments and acquisitions; (iv) merge or consolidate with others; (v) dispose of assets; (vi) pay dividends and distributions; (vii) pay junior indebtedness; and (viii) enter into affiliate transactions, in each case, subject to customary exceptions. In addition, the Credit Agreement contains financial covenants requiring the Company to maintain, on a consolidated basis as of the last day of each

13

quarterly period, a Consolidated Total Net Leverage Ratio of not more than 5.0 to 1.0 (which may be increased in connection with a material acquisition to 5.5 to 1.0 for a four quarter period up to three times during the term of the Credit Agreement) and a Consolidated Interest Coverage Ratio (as defined in the Credit Agreement) of at least 3.0 to 1.0. The Credit Agreement also includes events of default customary for facilities of this type and upon the occurrence of such events of default, among other things, all outstanding loans under the Credit Agreement may be accelerated, lenders commitments terminated, and/or the lenders may exercise collateral remedies. At September 30, 2025, the Company was in compliance with all financial covenants.

During the nine months ended September 30, 2025, the Company borrowed $760.0 million on the Revolving Facility and repaid $550.0 million of the balance outstanding.

At September 30, 2025, the Company had $786.7 million of availability under the Revolving Facility and had standby letters of credit outstanding of $3.3 million related to security for the payment of claims required by its workers’ compensation insurance program.

Prior Credit Facility

On March 17, 2021, the Company entered into a credit agreement (as amended, the “Prior Credit Facility”), which provided for a $600.0 million senior secured revolving credit facility (the “Prior Revolving Facility”) and a senior secured term loan facility in an initial principal amount of $425.0 million, which amount was later increased by $350.0 million (as increased, the “Prior Term Loan Facility”), each of which was scheduled to mature on March 17, 2026. The Prior Revolving Facility further provided for a $20.0 million subfacility for the issuance of letters of credit.

During the nine months ended September 30, 2025, the Company borrowed $115.0 million on the Prior Revolving Facility and repaid $485.0 million of the balance outstanding. During the nine months ended September 30, 2024, the Company borrowed $210.0 million on the Prior Revolving Facility and repaid $15.0 million of the balance outstanding.

On February 28, 2025, the Company refinanced the Prior Credit Facility by using the proceeds of the Credit Facility to repay the outstanding balances of the Prior Term Loan Facility and the Prior Revolving Facility, which totaled $670.9 million and $485.0 million, respectively. In connection therewith, the Company recorded a loss on extinguishment of $1.3 million, which is included in debt extinguishment costs in the condensed consolidated statements of income.

Senior Notes

5.500% Senior Notes due 2028

On June 24, 2020, the Company issued $450.0 million of 5.500% Senior Notes due 2028 (the “5.500% Senior Notes”). The 5.500% Senior Notes mature on July 1, 2028 and bear interest at a rate of 5.500% per annum, payable semi-annually in arrears on January 1 and July 1 of each year, commencing on January 1, 2021.

5.000% Senior Notes due 2029

On October 14, 2020, the Company issued $475.0 million of 5.000% Senior Notes due 2029 (the “5.000% Senior Notes”). The 5.000% Senior Notes mature on April 15, 2029 and bear interest at a rate of 5.000% per annum, payable semi-annually in arrears on April 15 and October 15 of each year, commencing on April 15, 2021.

7.375% Senior Notes due 2033

On March 10, 2025, the Company issued $550.0 million of 7.375% Senior Notes due 2033 (the “7.375% Senior Notes”). The 7.375% Senior Notes mature on March 15, 2033 and bear interest at a rate of 7.375% per annum, payable semi-annually in arrears on March 15 and September 15 of each year, commencing on September 15, 2025. The net proceeds from the issuance and sale of the 7.375% Senior Notes, together with cash on hand, were used to pay down $550.0 million of outstanding borrowings under the Revolving Facility.

The indentures governing the 5.500% Senior Notes, the 5.000% Senior Notes and the 7.375% Senior Notes (together, the “Senior Notes”) contain 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 Senior Notes issued by the Company are guaranteed by each of the Company’s subsidiaries that guarantee the Company’s obligations under the Credit Agreement. The guarantees are full and unconditional and joint and several.

The Company may redeem the Senior Notes at its option, in whole or part, at the dates and amounts set forth in the applicable indentures.

Noncontrolling Interests

Noncontrolling interests in the condensed consolidated financial statements represent the portion of equity held by noncontrolling partners in the Company’s non-wholly owned subsidiaries. At September 30, 2025, the Company operated 15 facilities through non-wholly owned subsidiaries. The Company owns between approximately 65% and 88% of the equity interests of these entities and noncontrolling partners own the remaining equity interests. The initial value of the noncontrolling interests is based on the fair value of contributions. The Company consolidates the operations of each facility based on its status as primary beneficiary, as further discussed in Note 13 – Variable Interest Entities. The noncontrolling interests are reflected as redeemable noncontrolling interests on the accompanying condensed consolidated balance sheets based on put rights that could require the Company to purchase the noncontrolling interests upon the occurrence of a change in control.

The components of redeemable noncontrolling interests are as follows (in thousands):

Balance at January 1, 2024 |  | $ | 105,686 |
Contributions from noncontrolling partners in joint ventures |  |  | 5,530 |
Net income attributable to noncontrolling interests |  |  | 8,872 |
Distributions to noncontrolling partners in joint ventures |  |  | (2,972 | )

Variable Interest Entities

For legal entities where the Company has a financial relationship, the Company evaluates whether it has a variable interest and determines if the entity is considered a variable interest entity (“VIE”). If the Company concludes an entity is a VIE and the Company is the primary beneficiary, the entity is consolidated. The primary beneficiary analysis is a qualitative analysis based on power and benefits. A reporting entity has a controlling financial interest in a VIE and must consolidate the VIE if it has both power and benefits. It must have the power to direct the activities that most significantly impact the VIE’s economic performance and the obligation to absorb losses of the VIE that potentially could be significant to the VIE or the right to receive benefits from the VIE that potentially could be significant to the VIE.

At September 30, 2025, the Company operated 15 facilities through non-wholly owned subsidiaries. The Company owns between approximately 65% and 88% of the equity interests of these entities, and noncontrolling partners own the remaining equity interests. The Company manages each of these facilities, is responsible for the day to day operations and, therefore, has the power to direct the activities that most significantly impact the VIE’s economic performance and the obligation to absorb losses or receive benefits from the VIE that could potentially be significant to the VIE. These activities include, but are not limited to, behavioral healthcare services, human resource and employment-related decisions, marketing and finance. The terms of the agreements governing each of the Company’s VIEs prohibit the Company from using the assets of each VIE to satisfy the obligations of other entities.

Equity-Based Compensation

Equity Incentive Plans

The Company issues stock-based awards, including stock options, restricted stock units and performance stock units, to certain officers, employees and non-employee directors under the Acadia Healthcare Company, Inc. Amended and Restated Incentive Compensation Plan (the “Equity Incentive Plan”). At September 30, 2025, a maximum of 15,175,000 shares of the Company’s common stock were authorized for issuance as stock options, restricted stock units and performance stock units or other share-based compensation under the Equity Incentive Plan, of which 3,418,793 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% or 33% each year, commencing one year after the date of grant. The exercise prices of stock options are equal to the closing price of the Company’s common stock on the most recent trading date prior to the date of grant.

The Company recognized $6.0 million and $9.5 million in equity-based compensation expense for the three months ended September 30, 2025 and 2024, respectively, and $25.3 million and $27.0 million for the nine months ended September 30, 2025 and 2024, respectively. Stock compensation expense for the three and nine months ended September 30, 2025 and 2024 is impacted by forfeiture adjustments. Stock compensation expense for the nine months ended September 30, 2025 and 2024 is also impacted by performance stock unit adjustments based on actual performance compared to vesting targets. At September 30, 2025, there was $67.8 million of unrecognized compensation expense related to unvested options, restricted stock units and performance stock units, which is expected to be recognized over the remaining weighted-average vesting period of 1.0 year.

The Company recognized a deferred income tax benefit of $1.0 million and $2.6 million for the three months ended September 30, 2025 and 2024, respectively, and $6.2 million and $7.3 million for the nine months ended September 30, 2025 and 2024, respectively, related to equity-based compensation expense.

Fair values are estimated using the Black-Scholes option pricing model. There were no stock options granted during the three and nine months ended September 30, 2025. The fo llowing table summarizes the grant-date fair value of options and the assumptions used to develop the fair value estimates for options granted during the year ended December 31, 2024:

|  | December 31, 2024 |
Weighted average grant-date fair value of options |  | $ | 27.24 |
Risk-free interest rate |  |  | 4.4 | %
Expected volatility |  |  | 33 | %
Expected life (in years) |  |  | 4.8 |

The Company’s estimate of expected volatility for stock options is based upon the volatility of its stock price over the expected life of the award. The risk-free interest rate is the approximate yield on U.S. 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.

Other Stock-Based Awards

Restricted stock unit activity during 2024 and 2025 was as follows:

Restricted stock unit awards are time-based vesting awards that vest over a period of three or four years and are subject to continuing service of the employee or non-employee director over the ratable vesting periods. The fair values of the restricted stock unit awards were determined based on the closing price of the Company’s common stock on the trading date immediately prior to the grant date.

Performance stock units are granted to employees and are subject to Company performance compared to pre-established targets. In addition to Company performance, these performance-based stock units are subject to the continuing service of the employee during the three-year period covered by the awards. The performance conditions for the performance stock units are based on the Company’s achievement of annually established targets for one- to three-year cumulative diluted earnings per share, adjusted earnings before interest, income taxes, depreciation and amortization, revenue and/or non-financial clinical excellence measurements. The number of shares issuable at the end of the applicable vesting period of performance stock units ranges from 0% to 200% of the targeted units based on the Company’s actual performance compared to the targets.

The fair values of performance stock units were determined based on the closing price of the Company’s common stock on the trading date immediately prior to the grant date for units subject to performance conditions.

15.
Share Repurchase Program

On February 25, 2025, the Company’s board of directors authorized a share repurchase program (the “Share Repurchase Program”) pursuant to which the Company may, from time to time, acquire up to $300.0 million of outstanding shares of its common stock, exclusive of any fees, commissions, or other expenses related to such repurchases. Repurchases made pursuant to the Share Repurchase Program will be made in accordance with applicable securities laws and may be made at management’s discretion from time to time in the open market, in privately negotiated transactions, or through block trades, derivatives transactions, or purchases made in accordance with Rule 10b-18 and Rule 10b5-1 of the Exchange Act. The Share Repurchase Program has no termination date and may be modified, suspended or discontinued by the Company’s board of directors at any time. The authorization does not obligate the Company to repurchase any shares. During the nine months ended September 30, 2025, the Company repurchased 1,706,625 shares of its common stock under the Share Repurchase Program that were each cancelled at the time of repurchase for a total of $50.4 million. As of September 30, 2025, there was $250.0 million of authorization remaining under the Share Repurchase Program.

Transaction, legal and other costs

Transaction, legal and other costs represent costs primarily related to legal, accounting, government investigation, termination, restructuring, management transition, acquisition and other similar costs. Transaction, legal and other costs comprised the following costs for the three and nine months ended September 30, 2025 and 2024 (in thousands):

| Three Months Ended September 30, |  |  | Nine Months Ended September 30, |
| 2025 |  |  | 2024 |  |  | 2025 |  |  | 2024 |

Termination and restructuring costs |  | 3,206 |  |  |  | 718 |  |  |  | 15,446 |  |  |  | (1,263 | )
Legal, accounting and other acquisition-related costs |  | 976 |  |  |  | 2,939 |  |  |  | (304 | ) |  |  | 9,730 |
Management transition costs |  | — |  |  |  | 1,490 |  |  |  | — |  |  |  | 3,085 |
Total | $ | 42,919 |  |  | $ | 8,249 |  |  | $ | 138,416 |  |  | $ | 17,187 |

Government investigations include legal fees and settlement costs related to certain litigation, including the matters referenced in Note 9 – Commitments and Contingencies. Termination and restructuring costs include costs, net of gains, incurred related to workforce reductions, contract amendments, and the closure and disposition of certain facilities, including related lease terminations. Legal, accounting and other acquisition-related costs include costs incurred for the development of new facilities ($0.5 million and $1.9 million for the three months ended September 30, 2025 and 2024, respectively, and $1.9 million and $3.9 million for the nine months ended September 30, 2025 and 2024, respectively); legal and settlement costs incurred related to certain litigation not included in government investigations ($0.4 million and $0.1 million for the three months ended September 30, 2025 and 2024, respectively, and $(2.3) million and $4.5 million for the nine months ended September 30, 2025 and 2024, respectively); and direct costs associated with acquisitions ($0.1 million and $1.0 million for the three months ended September 30, 2025 and 2024, respectively, and $0.1 million and $1.4 million for the nine months ended September 30, 2025 and 2024, respectively). 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 the Company’s Chief Executive Officer beginning in the first quarter of 2022 concluded in the fourth quarter of 2024.

17.
Income Taxes

The provision for income taxes for the three months ended September 30, 2025 and 2024 reflects effective tax rates of 4.2% and 27.6%, respectively, and 17.5% and 24.0% for the nine months ended September 30, 2025 and 2024, respectively. The decrease in the effective tax rate for both the three and nine months ended September 30, 2025 was primarily attributable to the Company’s lower pre-tax results for both the three and nine months ended September 30, 2025, which yields higher volatility in the items impacting the effective tax rate when compared to prior periods and the release of uncertain tax positions in the current year.

As the Company continues to monitor the implications of potential tax legislation in each of its jurisdictions, the Company may adjust estimates and record additional amounts for tax assets and liabilities. Any adjustments to the Company’s tax assets and liabilities could materially impact the provision for income taxes and its effective tax rate in the periods in which they are made.

18.
Fair Value Measurements

The carrying amounts reported for cash and cash equivalents, accounts receivable, other current assets, accounts payable and other current liabilities approximate fair value because of the short-term maturity of these instruments.

The Credit Facility, the Prior Credit Facility, and the Senior Notes 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.

19.
Segments

The Company has one reportable segment, behavioral healthcare services. The behavioral healthcare services segment provides inpatient and outpatient behavioral healthcare services. The Company derives revenue from 40 states and Puerto Rico and manages business activities on a consolidated basis. Revenue is primarily derived from services rendered to patients for inpatient psychiatric and substance abuse care, outpatient psychiatric care and adolescent residential treatment.

The Company’s Chief Operating Decision Maker (“CODM”) is the Chief Executive Officer. The CODM assesses performance for the behavioral healthcare services segment and decides how to allocate resources based on earnings before interest, income taxes, depreciation and amortization (“EBITDA”). The CODM reviews expenses in a format consistent with the condensed consolidated statements of income. The measure of segment assets is reported on the balance sheet as total assets.

The CODM uses EBITDA to evaluate income generated from segment assets in deciding whether to reinvest assets into the behavioral healthcare services segment or into other parts of the entity, such as for acquisitions or debt reduction. EBITDA is used to monitor budget versus actual results. The CODM also uses EBITDA in competitive analysis by benchmarking to the Company’s competitors. The competitive analysis along with the monitoring of budgeted versus actual results are used in assessing performance of the segment and in establishing management’s compensation. The Company does not have intra-entity sales or transfers.

Overview

Our business strategy is to become the indispensable behavioral healthcare provider for the high-acuity and complex needs patient population. We are committed to providing the communities we serve with high-quality, cost-effective behavioral healthcare services, while growing our business, increasing profitability and creating long-term value for our stockholders. This strategy includes five growth pathways: expansions of existing facilities, joint venture partnerships, de novo facilities, acquisitions and expansion across our continuum of care. At September 30, 2025, we operated 278 behavioral healthcare facilities with approximately 12,500 beds in 40 states and Puerto Rico. During the nine months ended September 30, 2025, we added 908 beds, consisting of 274 beds added to existing facilities and 634 beds added through the opening of one wholly-owned facility and four joint venture facilities, and we opened 14 CTCs.

We are the leading publicly traded pure-play provider of behavioral healthcare services in the U.S. Management believes that we are positioned as a leading platform in a highly fragmented industry under the direction of an experienced management team that has significant industry expertise. Management expects to take advantage of several strategies that are more accessible as a result of our increased size and geographic scale, including continuing a national marketing strategy to attract new patients and referral sources, increasing our volume of out-of-state referrals, providing a broader range of services to new and existing patients and clients and selectively pursuing opportunities to expand our facility and bed count through acquisitions, wholly-owned de novo facilities, joint ventures and bed additions in existing facilities.

Recent Legislative Developments

The One Big Beautiful Bill Act (“OBBBA”), enacted on July 4, 2025, includes various healthcare policy changes, including changes to the Medicaid program. Among other changes, OBBBA includes work or community engagement requirements for adults under the age of 65 in the Medicaid expansion population. We do not expect a material impact on our operations as these requirements begin to be phased in during 2026, primarily due to exemptions for the populations we serve, including individuals with chronic substance use disorders and those with serious and complex medical conditions.

OBBBA also makes significant changes to Medicaid financing mechanisms beginning in 2028, including restrictions on provider tax arrangements that are intended to reduce the federal matching funds received by state Medicaid programs. The law prohibits states from establishing new provider taxes or increasing rates of existing provider taxes while also limiting the structure of such taxes. The law also directs the U.S. Department of Health and Human Services to revise regulations governing state directed payment programs, which many states have implemented to direct certain Medicaid managed care expenditures, to cap total payments rates for specified services including hospital services.

We believe that we are well positioned to help meet the growing demand for behavioral healthcare services and recorded revenue growth of 4.7% for the nine months ended September 30, 2025 compared to the nine months ended September 30, 2024. Consistent with many other healthcare providers and other industries across the country, we continue to navigate a tight labor market. While we experienced higher wage inflation compared to historical averages in recent years, we continue to see stability in our labor costs, and our proactive focus helps us manage through this environment. We remain focused on ensuring that we have the level of staff to meet the demand in our markets across 40 states and Puerto Rico.

The following table sets forth percent changes in same facility operating data for the three and nine months ended September 30, 2025 compared to the same periods in 2024:

|  | Three Months Ended |  | Nine Months Ended
Same Facility Results (a) |  |  |  |
Revenue growth |  | 3.7% |  | 5.1%
Patient days growth |  | 1.3% |  | 1.8%
Admissions growth |  | 3.3% |  | 2.3%
Average length of stay change (b) |  | -1.9% |  | -0.5%
Revenue per patient day growth |  | 2.3% |  | 3.3%

(a)
Results for the periods presented include facilities we have operated more than one year and exclude certain closed services.
(b)
Average length of stay is defined as patient days divided by admissions.

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, and also 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 same 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 same facility results by ensuring those costs directly associated with facility operations are captured at the facility level for reporting.

We believe that providing results on a same 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 and 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 our 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 metrics 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.

Same facility results reflect adjustments that are intended to provide the specific presentation described above and 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. Same facility results may therefore not be indicative of the overall performance of our business, and should not be considered as an alternative for net income or any other performance measures derived in accordance with GAAP.

Consistent with same facility revenue growth in 2024, the growth in same facility patient days for the three months ended September 30, 2025 compared to the three months ended September 30, 2024 resulted from the addition of beds to our existing facilities and ongoing demand for our services.

| Three Months Ended September 30, |
| 2025 |  |  | 2024 |

Provision for income taxes. For the three months ended September 30, 2025, the provision for income taxes was $1.7 million, reflecting an effective tax rate of 4.2%, compared to $27.2 million, reflecting an effective tax rate of 27.6%, for the three months ended September 30, 2024. The decrease in the effective tax rate for the three months ended September 30, 2025 was

26

primarily attributable to the Company’s lower pre-tax results for the three months ended September 30, 2025, which yields higher volatility in the items impacting the effective tax rate when compared to prior periods and the release of uncertain tax positions in the current year.

As we continue to monitor the implications of potential tax legislation in each of our jurisdictions, we may adjust our estimates and record additional amounts for tax assets and liabilities. Any adjustments to our tax assets and liabilities could materially impact our provision for income taxes and our effective tax rate in the periods in which they are made.

Revenue

Our revenue is primarily derived from services rendered to patients for inpatient psychiatric and substance abuse care, outpatient psychiatric care and adolescent residential treatment. We receive payments from the following sources for services rendered in our facilities: (i) state governments under their respective Medicaid and other programs; (ii) commercial insurers; (iii) the federal government under the Medicare program administered by CMS and other programs; and (iv) individual patients and clients. We determine the transaction price based on established billing rates reduced by contractual adjustments provided to third-party payors, discounts provided to uninsured patients and implicit price concessions. Contractual adjustments and discounts are based on contractual agreements, discount policies and historical experience. Implicit price concessions are based on historical collection experience.

Our strategic plan does not require the repatriation of foreign cash in order to fund our operations in the U.S.

Desert Hills Litigation

As described in more detail in Note 9 – Commitments and Contingencies in the accompanying notes to our condensed consolidated financial statements, on October 30, 2023, we entered into settlement agreements in connection with the Cases. The settlement agreements for the Cases were approved by the District Court in December 2023 and fully resolved each of the Cases with no admission of liability or wrongdoing by us or Desert Hills. On January 19, 2024, pursuant to the terms of the settlement agreements, we paid an aggregate amount of $400.0 million in exchange for the release and discharge of all claims arising from, relating to, concerning or with respect to all harm, injuries or damages asserted in the Cases or that may be asserted in the future by the plaintiffs in the Cases.

Credit Facility

On the Credit Facility Closing Date, we entered into the Credit Agreement, which provides for the $1.0 billion Revolving Facility (including a $50.0 million sublimit for the issuance of letters of credit and a $50.0 million swingline subfacility) and the $650.0 million Term Loan Facility, each maturing on February 28, 2030.

On the Credit Facility Closing Date, the full $650.0 million amount of the Term Loan Facility was funded, and $550.0 million was funded under the Revolving Facility, which amounts were used, among other things, to refinance the outstanding obligations under the Prior Credit Facility.

Borrowings under the Credit Agreement bear interest at a floating rate equal to, at our option, either (i) a SOFR-based rate plus a margin ranging from 1.375% to 2.250% or (ii) a base rate plus a margin ranging from 0.375% to 1.250%, in each case, depending on our Consolidated Total Net Leverage Ratio. In addition, an unused fee that varies according to our Consolidated Total Net Leverage Ratio ranging from 0.200% to 0.350% is payable quarterly in arrears based on the average daily undrawn portion of the commitments in respect of the Revolving Facility. The Term Loan Facility requires quarterly principal repayments of $4.0 million through March 31, 2026, $8.1 million from June 30, 2026 to March 31, 2028, $12.2 million from June 30, 2028 to March 31, 2029 and $16.2 million from June 30, 2029 to December 31, 2029, with the remaining outstanding principal balance of the Term Loan Facility due on the maturity date of February 28, 2030.

We have the ability to increase the amount of the Credit Facility, which may take the form of increases to the Revolving Facility or the Term Loan Facility or the issuance of one or more Incremental Facilities, upon obtaining additional commitments from new or existing lenders and the satisfaction of certain customary conditions precedent for such Incremental Facilities. Such Incremental Facilities may not exceed the sum of (i) the greater of $710.0 million and an amount equal to 100% of our LTM Consolidated EBITDA at the time of determination and (ii) additional amounts that would not cause our Consolidated Senior Secured Net Leverage Ratio to exceed 4.0 to 1.0.

Subject to certain exceptions, substantially all of our existing and subsequently acquired or organized direct and indirect wholly-owned U.S. subsidiaries are required to guarantee the repayment of our obligations under the Credit Agreement. The obligations of us and such guarantor subsidiaries are secured by a pledge of substantially all of our and such guarantor subsidiaries’ assets (excluding all real property and certain other customarily excluded assets).

The Credit Agreement contains customary representations and warranties and affirmative and negative covenants, including limitations on the ability of us and our subsidiaries to: (i) incur debt; (ii) permit additional liens; (iii) make investments and acquisitions; (iv) merge or consolidate with others; (v) dispose of assets; (vi) pay dividends and distributions; (vii) pay junior indebtedness; and (viii) enter into affiliate transactions, in each case, subject to customary exceptions. In addition, the Credit Agreement contains financial covenants requiring us to maintain, on a consolidated basis as of the last day of each quarterly period, a Consolidated Total Net Leverage Ratio of not more than 5.0 to 1.0 (which may be increased in connection with a material acquisition to 5.5 to 1.0 for a four quarter period up to three times during the term of the Credit Agreement) and a Consolidated Interest Coverage Ratio of at least 3.0 to 1.0. The Credit Agreement also includes events of default customary for facilities of this type and upon the

30

occurrence of such events of default, among other things, all outstanding loans under the Credit Agreement may be accelerated, lenders commitments terminated, and/or lenders may exercise collateral remedies. At September 30, 2025, our Consolidated Total Net Leverage Ratio was 3.4x, and we were in compliance with all financial covenants. Consolidated Total Net Leverage Ratio is being reported as calculated under the Credit Agreement and not pursuant to GAAP. Investors should refer to the agreements governing the Credit Agreement attached as exhibits to our periodic reports for further information related to the calculation thereof and should not consider Consolidated Total Net Leverage Ratio as an alternative for any measures derived in accordance with GAAP. For risks related to our indebtedness and compliance with these covenants, see “Item 1A. Risk Factors” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024.

During the nine months ended September 30, 2025, we borrowed $760.0 million on the Revolving Facility and repaid $550.0 million of the balance outstanding.

At September 30, 2025, we had $786.7 million of availability under the Revolving Facility and had standby letters of credit outstanding of $3.3 million related to security for the payment of claims required by our workers’ compensation insurance program.

Prior Credit Facility

On March 17, 2021, we entered into the Prior Credit Facility, which provided for the Prior Revolving Facility and the Prior Term Loan Facility, each of which was scheduled to mature on March 17, 2026.

During the nine months ended September 30, 2025, we borrowed $115.0 million on the Prior Revolving Facility and repaid $485.0 million of the balance outstanding. During the nine months ended September 30, 2024, we borrowed $210.0 million on the Prior Revolving Facility and repaid $15.0 million of the balance outstanding.

On February 28, 2025, we refinanced the Prior Credit Facility by using the proceeds of the Credit Facility to repay the outstanding balances of the Prior Term Loan Facility and the Prior Revolving Facility, which totaled $670.9 million and $485.0 million, respectively. In connection therewith, we recorded a loss on extinguishment of $1.3 million, which is included in debt extinguishment costs in the condensed consolidated statements of income.

Senior Notes

5.500% Senior Notes due 2028

On June 24, 2020, we issued $450.0 million of 5.500% Senior Notes. The 5.500% Senior Notes mature on July 1, 2028 and bear interest at a rate of 5.500% per annum, payable semi-annually in arrears on January 1 and July 1 of each year, commencing on January 1, 2021.

5.000% Senior Notes due 2029

On October 14, 2020, we issued $475.0 million of 5.000% Senior Notes. The 5.000% Senior Notes mature on April 15, 2029 and bear interest at a rate of 5.000% per annum, payable semi-annually in arrears on April 15 and October 15 of each year, commencing on April 15, 2021.

7.375% Senior Notes due 2033

On March 10, 2025, we issued $550.0 million of 7.375% Senior Notes.

The net proceeds from the issuance and sale of the 7.375% Senior Notes, together with cash on hand, were used to pay down $550.0 million of outstanding borrowings under the Revolving Facility.

The indentures governing the Senior Notes contain covenants that, among other things, limit our ability and the ability of our 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 our assets; and (vii) create liens on assets.

The Senior Notes issued by us are guaranteed by each of our subsidiaries that guarantee our obligations under the Credit Agreement. The guarantees are full and unconditional and joint and several.

We may redeem the Senior Notes at our option, in whole or part, at the dates and amounts set forth in the applicable indentures.

Item 3. Quantitative and Qualitat ive Disclosures About Market Risk

Interest Rate Risk

Our interest expense is sensitive to changes in market interest rates. Our long-term debt outstanding at September 30, 2025 was composed of $1,461.5 million of fixed-rate debt and $847.6 million of variable-rate debt with interest based on Adjusted Term SOFR plus an applicable margin. Based on our borrowing level at September 30, 2025, a hypothetical 1% increase in interest rates would decrease our pretax income on an annual basis by approximately $8.5 million.

Item 4. Control s and Procedures

Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this report, our management conducted an evaluation, with the participation of our chief executive officer and chief financial officer, of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). Based on this evaluation, our chief executive officer and chief financial officer have concluded that our disclosure controls and procedures are effective to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to management, including our chief executive officer and chief financial officer, as appropriate to allow timely decisions regarding required disclosure.
