 Exhibit 10.1 

EMPLOYMENT AGREEMENT 

THIS EMPLOYMENT AGREEMENT (this “Agreement”) is made and entered into as of January 19, 2021 by and between Acadia
Management Company, Inc., a Delaware corporation (the “Company”), and Debra K. Osteen (“Executive”). 

WHEREAS, the Company and the Executive are a party to that certain Employment Agreement, dated as of December 16, 2018 (the
“Original Employment Agreement”); 
 WHEREAS, Original Employment Agreement expired on December 31, 2020; and 

WHEREAS, the Company and the Executive desire to enter into a new employment agreement as provided herein, effective as of the date hereof;

 NOW, THEREFORE, in consideration of the mutual covenants contained herein and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto agree as follows: 
 1. Employment; Employment Period. The Company
shall continue to employ Executive, and Executive hereby accepts continued employment with the Company, upon the terms and conditions set forth in this Agreement for the period beginning as of January 1, 2021 and ending on December 31,
2021 (the “Employment Period”). Notwithstanding the foregoing, Executive’s employment hereunder may be earlier terminated in accordance with (and subject to) Section 4 hereof. The place of employment
of Executive shall be the principal executive offices and corporate headquarters of the Company and Acadia Healthcare Company, Inc., a Delaware corporation (“Acadia”), which, during the Employment Period, shall be located in
Williamson County, Tennessee. Executive will spend substantially all Executive’s business time in the Williamson County, Tennessee corporate office (other than while traveling for business purposes). 

2. Position and Duties. 

(a) Position; Responsibilities. During the Employment Period, Executive shall serve as the Chief Executive Officer of Acadia, and shall
have the normal duties, responsibilities, functions and authority of a chief executive officer in similarly sized companies that are not inconsistent with Executive’s position as Chief Executive Officer, subject to the power and authority of
the board of directors (the “Board”) of Acadia, to expand or limit such duties, responsibilities, functions and authority within the scope of duties, responsibilities, functions and authority associated with the position of Chief
Executive Officer and to overrule actions of officers of the Company. Acadia shall cause the nominating and corporate governance committee of the Board (the “Nominating Committee”) to nominate Executive to serve as a member of the
Board each year during the Employment Period that Executive’s term of Board service is to be slated for reelection to the Board. If the Company’s stockholders vote in favor of the Nominating Committee’s nomination of Executive to
serve as a member of the Board, Executive agrees to serve in such capacity. During the Employment Period, Executive agrees to serve on all other boards of directors of Subsidiaries of the Company or its affiliates and Executive agrees that any such
board service shall be without additional compensation. 












 (b) Reporting; Performance of Duties. Executive shall report to the Board and
all employees of Acadia and its Subsidiaries shall report to Executive or her designee(s). Executive shall devote substantially all of her business time and attention (except for permitted vacation periods and reasonable periods of illness or other
incapacity) to the business and affairs of Acadia and the Subsidiaries. So long as Executive is employed by the Company, Executive shall not, without the prior written consent or approval of the Board, perform other services for compensation.
Notwithstanding the foregoing, nothing herein shall preclude Executive from (i) serving, with the prior written consent of the Board, as a member of the boards of directors or advisory boards (or their equivalents in the case of a non-corporate entity) of for-profit companies or businesses which are not directly competitive with the Company or any Subsidiary (provided that the prior written consent of
the Board shall not be required for Executive to serve as a member of the boards of directors or advisory boards (or their equivalents) of the companies listed on Exhibit A, (ii) engaging in charitable activities and community affairs
(including serving as a member of the boards of directors or advisory boards (or their equivalents in the case of a non-corporate entity) of
not-for-profit, charitable or community organizations which are not directly competitive with the Company or any Subsidiary); and (iii) managing Executive’s
personal and legal affairs and her passive personal investments; provided, however, the activities set out in clauses (i) and (ii) above shall be limited by Executive so as not to materially interfere, individually or in the aggregate, with the
performance of her duties and responsibilities hereunder. For the avoidance of doubt, so long as Executive is employed by the Company, Executive shall not provide any services to any company or business that is directly competitive with Acadia or
the Subsidiaries (whether for-profit or not-for-profit) without the prior written consent of the Board. 

3. Compensation and Benefits. 

(a) Base Salary. During the Employment Period, Executive’s base salary shall be $1,000,000 per annum, subject to increase by the
Board or Acadia’s Compensation Committee (the “Compensation Committee”) (as increased from time to time, the “Base Salary”), which salary shall be payable by the Company in regular installments in accordance
with the Company’s general payroll practices (as in effect from time to time). The Base Salary for any partial year during the Employment Period will be based upon the actual number of days elapsed in such year. 

(b) Business Expenses. During the Employment Period, the Company shall reimburse Executive in the calendar year in which they are
incurred for all reasonable out-of-pocket business expenses incurred by her in the course of performing her duties and responsibilities under this Agreement which are consistent with the Company’s
policies in effect from time to time with respect to travel, entertainment and other business expenses, subject to the Company’s requirements with respect to reporting and documentation of such expenses. 

(c) Bonus. In addition to the Base Salary, during the calendar year ending December 31, 2021, Executive will be eligible to earn a
target annual cash bonus of 100% of Executive’s Base Salary (the “Target Bonus”), with a range of 0% for performance below threshold performance, 50% of Base Salary at threshold performance, up to a maximum cash bonus
determined in accordance with the Company’s annual bonus plan for senior executives (which for Executive shall be 200% of Base Salary), if and only if Executive, Acadia and the Subsidiaries achieve the performance criteria specified by the
Board or the Compensation Committee for such year, as determined by the Board or the Compensation Committee in its sole 












 
discretion. The performance criteria for any particular year shall be set by the Board or the Compensation Committee no later than ninety (90) days after the commencement of the relevant
year, with 75% of such performance criteria to be based on financial goals that are consistent with other members of the senior management team and 25% to be based on qualitative, quantitative and other objectives known as the “Board
Objectives”, in each case, established by the Board or the Compensation Committee after consultation with Executive. Unless otherwise agreed to by Executive, any such bonus amount for any year shall be earned (if awarded) on the last day of
such year and paid by the Company in the calendar year following the calendar year to which such bonus has been earned and no later than the earlier of (x) the date that is ten (10) business days after the Company’s receipt of its
audited financial statements for the calendar year with respect to which such bonus has been earned and (y) December 31 of the calendar year following such year with respect to which such bonus has been earned, regardless of whether
Executive continues to be employed by the Company as of such payment date. 
 (d) Long-Term Incentive Compensation. Executive
will be entitled to a long-term incentive award in 2021 consisting entirely of performance restricted stock units (the “2021 Award”) that will have a target value equal to $5.2 million (such value to be determined on the same
basis as the Compensation Committee values such awards generally). The 2021 Award will have a one-year performance period ending December 31, 2021, with the following percentages of the target number of
shares vesting based on Executive’s continued employment until the end of the performance period and the applicable level of achievement against the performance goals: (i) 0%—less than threshold performance; (ii) 50%—threshold
performance; (iii) 100%—target performance; and (iv) 200%—maximum performance. The applicable performance criteria will be established by the Board or the Compensation Committee, with 75% of such performance criteria to be based on
financial goals that are consistent with other members of the senior management team and 25% to be based on the Board Objectives, in each case, established by the Board or the Compensation Committee after consultation with Executive. 

(e) Benefits. In addition to (but without duplication of) the Base Salary and any bonuses payable to Executive pursuant to this
Section 3, Executive shall be entitled to participate at her sole discretion in all of the Company’s employee benefit programs for which senior executive employees of the Company are generally eligible. 

(f) Counsel Fees. Upon presentation of appropriate documentation, the Company shall pay Executive’s reasonable counsel fees
incurred in connection with the negotiation and documentation of this Agreement in an amount up to $35,000, and matters related hereto, payable within thirty (30) days following the execution of this Agreement. 

4. Termination. 
 (a)
Termination. The Employment Period shall terminate automatically and immediately upon Executive’s resignation for any reason (whether with Good Reason or without Good Reason), Executive’s death or becoming Disabled, or upon the
termination of Executive’s employment by the Company (through action by the Board) for any reason (whether for Cause or without Cause). The date on which Executive ceases to be employed by the Company is referred to herein as the

(iii) continued payment of the Executive’s Base Salary, payable in accordance with the Company’s general payroll

(iv) an amount equal to the actual annual cash bonus amount to which Executive would be entitled under
Section 3(c) with respect to the 2021 calendar year, determined based on achievement of the performance objectives specified in Executive’s bonus plan for such year (with any subjective performance criteria other than
the Board Objectives deemed achieved at target and the achievement of the Board Objectives to be determined in good faith by the Board based on Executive’s achievement against the Board Objectives in a manner consistent with how achievement is
measured for other executive officers of the Company), as determined by the Board or the Compensation Committee consistent with other senior executives of the Company, which amount shall not be prorated and paid as if Executive had remained employed
through December 31, 2021 (payable at the same time it would have been paid pursuant to Section 3(c)); 

(v) an amount equal to the after-tax cost of the premiums for continued health and

Objectives in a manner consistent with how achievement is measured for other executive officers). 
 Notwithstanding the foregoing, Executive shall be
entitled to receive such payments described in Section 4(b)(iii) through 4(b)(vi) only so long as Executive has not breached any of the provisions of Sections 5, 6 and 7 hereof, and all amounts payable
and benefits or additional rights provided pursuant to Section 4(b)(iii) through 4(b)(vi) shall only be payable if Executive delivers to the Company and does not revoke a general release of claims in favor of the Company in
substantially the form attached on Exhibit B hereto; such release shall be executed and delivered (and no longer subject to revocation, if applicable) within sixty (60) days following Executive’s termination (the “Release
Requirement”). 
 (c) Termination by Death or Disability. If Executive’s employment is terminated due to
Executive’s death or becoming Disabled, then Executive (or her estate or beneficiary) shall be entitled to receive:

other payments, benefits or fringe benefits to which Executive shall be entitled under the terms of any applicable compensation arrangement or benefit, equity or fringe benefit plan or program or grant or this Agreement; 

(iii) an amount equal to the actual annual cash bonus amount to which Executive would be entitled under
Section 3(c) with respect to the calendar year in which the Termination Date occurs, determined based on achievement of the performance objectives specified in Executive’s bonus plan for such year (with any subjective
performance criteria deemed achieved at target), as determined by the Board or the Compensation Committee consistent with other senior executives of the Company, which amount shall be prorated based on the actual number of days elapsed in such year
prior to the Termination Date (payable at the same time it would have been paid pursuant to Section 3(c)); 

  
 5 













 (iv) an amount equal to the
after-tax cost of the premiums for continued health and dental insurance for Executive and/or Executive’s dependents in accordance with COBRA for the period commencing on the Termination Date and ending
on the earliest of (A) the date on which Executive’s COBRA period terminates or expires, (B) six (6) months after the Termination Date, and (C) the date on which Executive becomes eligible for long-term disability benefits under
any long-term disability program sponsored by the Company (payable in monthly installments during and concurrently with Executive’s COBRA period); provided that if Executive’s COBRA period is terminated prior to expiration of the period
commencing on the Termination Date and ending on the earlier of (I) the date on which Executive becomes eligible for long-term disability benefits under any long-term disability program sponsored by the Company, and (II) six (6) months
after the Termination Date (such period, the “Disability Severance Period”), then Executive shall be entitled to continue to receive an amount equal to the cost of the premiums for continued health and dental insurance for Executive
and/or Executive’s dependents in accordance with COBRA (assuming such continued insurance coverage remained available at the same monthly cost) payable in monthly installments during the period commencing on the date of such termination or
expiration and ending on the date on which the Disability Severance Period expires; and 
 (v) with respect to the 2021
Award, to the extent that it shall not otherwise have become vested, (A) the service-based vesting requirement shall be deemed satisfied; and (B) the 2021 Award will remain outstanding and eligible to vest based on actual achievement of
the applicable performance conditions (with subjective performance criteria deemed to be achieved at target). 
 In addition, if Executive’s employment
is terminated due to Executive’s becoming Disabled (but, for the avoidance of doubt, not due to her death), then Executive (or her estate or beneficiary) shall be entitled to receive, during the Disability Severance Period, continued
installment payments of Executive’s Base Salary as in effect on the Termination Date, which shall be payable over the Disability Severance Period in regular installments in accordance with the Company’s general payroll practices as in
effect on the Termination Date, but in no event less frequently than monthly. 
 (d) Other Termination. If Executive’s
employment is terminated (i) by the Company for Cause, or (ii) by Executive’s resignation without Good Reason, then the Company shall pay Executive (A) Executive’s unpaid Base Salary through the Termination Date (payable in
accordance with Section 3(a)) and (B) any bonus amount under Section 3(c) to which Executive is entitled determined by reference to the calendar year that ended on or prior to the Termination

 (e) Treatment of 2019 and 2020 Equity Awards. If Executive’s employment with the
Company terminates for any reason other than a termination by the Company for Cause, annual equity and equity-based awards granted to Executive in 2019 and 2020 (the “2019 and 2020 Awards”) shall be treated as set forth
below, subject to Executive’s satisfaction of the Release Requirement: (i) the time or service vesting component(s) of the 2019 and 2020 Awards will be deemed satisfied upon such termination of employment; and (ii) 2019 and 2020 Awards
subject to performance-based vesting will remain outstanding and eligible to vest based on actual achievement of the applicable performance conditions, subject to the terms and conditions set forth in the applicable award agreement and/or governing
documentation. 
 (f) Continuation of Benefits. Upon any termination of employment, whether voluntary or otherwise, Executive shall
have the option to elect health insurance coverage for herself, her spouse and her eligible dependents during the period commencing on the end of the statutory COBRA period, if any (provided that Executive validly elected COBRA continuation
coverage), until the earlier of the date on which Executive (A) is eligible to participate in another health benefit plan (including, without limitation, a plan sponsored by a then current or former employer of Executive’s or
Executive’s spouse, other than a plan that provides for “excepted benefits” as defined under section 733(c) of the Employee Retirement Income Security Act of 1974) or (B) becomes eligible for Medicare. Such coverage will be
provided for by the Company (or any successor to the Company, whether by operation of law or otherwise) in accordance with applicable law, and Executive shall pay premiums consistent with other senior executive employees of the Company (or any
successor to the Company, whether by operation of law or otherwise). Executive agrees to take all required actions and provide any requested personal medical history and information, in accordance with the applicable policy application and medical
underwriting process. Nothing in this Section 4(g) shall decrease or reduce Executive’s rights or entitlements under Sections 4(b)(v) or 4(c)(v) hereof. 

(g) No Mitigation. Executive is under no obligation to mitigate damages or the amount of any payment provided for under this
Section 4 by seeking other employment or otherwise. 
 (h) Right of Offset. The Company may offset any bona
fide obligations that Executive owes Acadia or any of the Subsidiaries (which for the avoidance of doubt shall not include any unliquidated obligations or obligations to the extent Executive disputes in good faith the nature or amount thereof)
against any amounts the Company or any of the Subsidiaries owes Executive hereunder; provided that, notwithstanding the foregoing or any other provision of this Agreement to the contrary, in no event shall any payment under this Agreement that
constitutes “deferred compensation” for purposes of Code Section 409A be subject to offset, counterclaim or recoupment by any other amount unless otherwise permitted by Code Section 409A. 

(i) Section 409A Compliance. 

(i) The intent of the parties is that payments and benefits under this Agreement comply with Internal Revenue Code
Section 409A and the regulations and guidance promulgated thereunder (collectively “Code Section 409A”) and, accordingly, to the maximum extent permitted, this Agreement shall be interpreted to be in
compliance therewith. In no event whatsoever shall Acadia or any of the Subsidiaries be liable for any additional tax, interest or penalty that may be imposed on Executive by Code Section 409A or damages for failing to comply with Code
Section 409A. 

  
 7 













 (ii) A termination of employment shall not be deemed to have occurred for
purposes of any provision of this Agreement providing for the payment of any amounts or benefits upon or following a termination of employment unless such termination is also a “separation from service” within the meaning of Code
Section 409A and, for purposes of any such provision of this Agreement, references to a “termination,” “termination of employment,” “termination of the Employment Period” or like terms shall mean “separation
from service.” 
 (iii) All expenses or other reimbursements under this Agreement shall be made on or prior to the last
day of the taxable year following the taxable year in which such expenses were incurred by Executive (provided that if any such reimbursements constitute taxable income to Executive, such reimbursements shall be paid no later than March 15th of the
calendar year following the calendar year in which the expenses to be reimbursed were incurred), and no such reimbursement or expenses eligible for reimbursement in any taxable year shall in any way affect the expenses eligible for reimbursement in
any other taxable year. 
 (iv) For purposes of Code Section 409A, Executive’s right to receive any installment
payment pursuant to this Agreement shall be treated as a right to receive a series of separate and distinct payments. 
 (v)
Whenever a payment under this Agreement specifies a payment period with reference to a number of days (e.g., “payment shall be made within fifteen (15) days following the Termination Date”), the actual date of payment within the
specified period shall be within the sole discretion of the Company. 
 (vi) Notwithstanding any other payment schedule
provided herein to the contrary, if Executive is deemed on the Termination Date to be a “specified employee” within the meaning of that term under Code Section 409A(a)(2)(B), then any payment that is considered deferred compensation
under Code Section 409A payable on account of a “separation from service” shall be made on the date which is the earlier of (i) the expiration of the six (6)-month period measured from the date of such “separation from
service” of Executive and (ii) the date of Executive’s death (the “Delay Period”) to the extent required under Code Section 409A. Upon the expiration of the Delay Period, all payments delayed pursuant to the
immediately preceding sentence (whether they otherwise would have been payable in a single sum or in installments in the absence of such delay) shall be paid to Executive in a lump sum, and all remaining payments due under this Agreement shall be
paid or provided in accordance with the normal payment dates specified for them herein. In addition, if Executive is a “specified employee,” to the extent that welfare benefits to be provided to Executive pursuant to this Agreement are not
“disability pay,” “death benefit” plans or non-taxable medical benefits within the meaning of Treasury Regulation Section 1.409A-1(a)(5) or
other benefits not considered nonqualified deferred compensation within the meaning of that regulation, such provision of benefits shall be delayed until the end of the Delay Period. Notwithstanding the foregoing, to the extent that the previous
sentence applies to the provision of any ongoing health or welfare benefits that would not be 

  
 8 













 
required to be delayed if the premiums were paid by Executive, Executive shall pay the full cost of the premiums for such benefits during the Delay Period and the Company shall pay Executive an
amount equal to the amount of such premiums paid by Executive during the Delay Period within ten (10) days after the end of Delay Period. 

(j) Upon any termination of Executive’s employment with the Company, Executive shall promptly resign, and shall be automatically deemed
to have resigned without the requirement of any further action, from any position as an officer, director or fiduciary of Acadia and the Company and their respective Affiliates (including, without limitation the Board of Acadia). Executive agrees to
execute any additional documentation reasonably requested by the Company to implement any such resignation contemplated herein. 
 5.
Confidential Information. 
 (a) Protection of Confidential Information. Executive acknowledges that the continued success of
Acadia and the Subsidiaries depends upon the use and protection of a large body of confidential and proprietary information. All of such confidential and proprietary information now existing or to be developed in the future will be referred to in
this Agreement as “Confidential Information.” Confidential Information will be interpreted broadly to include, without limitation, all information that is (i) related to Acadia’s or the Subsidiaries’ (including any of
their predecessors’ prior to being acquired by the Company) current or potential business and (ii) is not generally or publicly known (including, without specific limitation, the information, observations and data concerning
(A) acquisition opportunities in or reasonably related to Acadia’s or the Subsidiaries’ business or industry, (B) identities and requirements of, contractual arrangements with and other information regarding Acadia’s or the
Subsidiaries’ employees (including personnel files and other information), suppliers, distributors, customers, independent contractors, third-party payors, providers or other business relations and their confidential information, including,
without limitation, patient records, medical histories and other information concerning patients (including, without limitation, all “Protected Health Information” within the meaning of the Health Insurance Portability and Accountability
Act), and (C) internal business information and intellectual property of every kind and description of Acadia and the Subsidiaries). Executive agrees that during the Employment Period and for five (5) years thereafter, she shall not
disclose to any unauthorized person or use for her own account any of such Confidential Information, whether or not developed by Executive, without the Board’s prior written consent, unless and to the extent that any Confidential Information
(i) was known to Executive prior to the negotiation of this Agreement or the Employment Period from a source (other than Acadia, the Subsidiaries or any of their respective agents) that, to the knowledge of Executive, was not prohibited from
disclosing such information by a legal, contractual or fiduciary obligation to Acadia or any of the Subsidiaries, (ii) becomes generally known to and available for use by the public other than as a result of Executive’s acts or omissions
to act or (iii) is required to be disclosed pursuant to any applicable law or court order. 
 (b) Use of Others’
Confidential Information. During the Employment Period, Executive shall not use or disclose any confidential information or trade secrets, if any, of any former employers or any other Person to whom Executive has an obligation of
confidentiality. If at any time during her employment with the Company, Executive believes she is being asked to engage in work that will, or will be likely to, jeopardize any confidentiality or other obligations Executive may have to former
employers, then Executive shall immediately advise the Board so that Executive’s duties can be modified appropriately. 

  
 9 













 (c) Third-Party Information. Executive understands that Acadia and the Subsidiaries
will receive from third parties confidential or proprietary information (“Third-Party Information”) subject to a duty on Acadia’s and the Subsidiaries’ part to maintain the confidentiality of such information and to use it
only for certain limited purposes. During the Employment Period and thereafter, and without in any way limiting the provisions of Section 5(a) above, Executive will hold Third-Party Information in the strictest confidence
and will not disclose to anyone (other than personnel of Acadia or the Subsidiaries who need to know such information in connection with their work for Acadia or the Subsidiaries) or use, except in connection with her work for Acadia or the
Subsidiaries, Third-Party Information unless expressly authorized by the Board in writing. 
 (d) Whistleblower Protection.
Notwithstanding anything to the contrary contained herein, no provision of this Agreement shall be interpreted so as to impede Executive (or any other individual) from reporting possible violations of federal law or regulation to any governmental
agency or entity, including but not limited to the Department of Justice, the Securities and Exchange Commission, the Congress, and any agency Inspector General, or making other disclosures under the whistleblower provisions of federal law or
regulation. Executive does not need the prior authorization of Acadia or any of the Subsidiaries to make any such reports or disclosures and Executive shall not be not required to notify the Acadia or any of the Subsidiaries that such reports or
disclosures have been made. 
 (e) Trade Secrets. 18 U.S.C. § 1833(b) provides: “An individual shall not be held criminally
or civilly liable under any Federal or State trade secret law for the disclosure of a trade secret that (A) is made (i) in confidence to a Federal, State, or local government official, either directly or indirectly, or to an attorney; and
(ii) solely for the purpose of reporting or investigating a suspected violation of law; or (B) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal.” Nothing in this
Agreement is intended to conflict with 18 U.S.C. § 1833(b) or create liability for disclosures of trade secrets that are expressly allowed by 18 U.S.C. § 1833(b). Accordingly, the parties to this Agreement have the right to disclose in
confidence trade secrets to federal, state, and local government officials, or to an attorney, for the sole purpose of reporting or investigating a suspected violation of law. The parties also have the right to disclose trade secrets in a document
filed in a lawsuit or other proceeding, but only if the filing is made under seal and protected from public disclosure. 
 6. Ownership
of Intellectual Property, Inventions and Patents. Executive acknowledges that all discoveries, concepts, ideas, inventions, innovations, improvements, developments, methods, processes, programs, designs, analyses, drawings, reports, patent
applications, copyrightable work and mask work (whether or not including any confidential information) and all registrations or applications related thereto, all other proprietary information and all similar or related information (whether or not
patentable) which relate to Acadia’s or the Subsidiaries’ actual or anticipated business, research and development or existing or future products or services and which are conceived, developed, contributed to, made or reduced to practice
by Executive (whether alone or jointly with others) while employed by Acadia or the 

  
 10 













 
Subsidiaries after the date of this Agreement, including any of the foregoing that constitutes any proprietary information or records (“Work Product”), belong to Acadia or such
Subsidiary. Any copyrightable work prepared in whole or in part by Executive in the course of her work for any of the foregoing entities shall be deemed a “work made for hire” to the maximum extent permitted under copyright laws, and
Acadia or such Subsidiary shall own all rights therein. To the extent any such copyrightable work is not a “work made for hire,” Executive hereby assigns and agrees to assign to Acadia or such Subsidiary all right, title and interest,
including, without limitation, copyright, in and to such copyrightable work. Executive shall promptly disclose such Work Product to the Board and, at the Company’s expense, perform all actions reasonably requested by the Board (whether during
or after the Employment Period) to establish and confirm such ownership by Acadia or such Subsidiary (including, without limitation, execution and delivery of assignments, consents, powers of attorney and other instruments). 

7. Non-Compete; Non-Solicit. 

(a) Non-Compete. In further consideration of the compensation to be paid to Executive
hereunder, Executive acknowledges that during the course of her employment with the Company she has and shall become familiar with Acadia’s and the Subsidiaries’ trade secrets and with other Confidential Information concerning Acadia and
the Subsidiaries and that her services have been and shall be of special, unique and extraordinary value to Acadia and the Subsidiaries, and, therefore, Executive agrees that, during the Employment Period and for a period thereafter of twenty-four
(24) months (the “Noncompete Period”), she shall not (i) directly or indirectly own any interest in, manage, control, participate in, consult with, render services for, or in any manner engage in any business that derives
at least 25% of its gross revenue from (A) the business of providing behavioral healthcare and/or related services, or (B) any other material business in which Acadia or any of its Subsidiaries planned to be engaged in on or after such
date of which the Executive has or should have had actual knowledge, or (ii) directly or indirectly manage, control, participate in, consult with or render services specifically with respect to any unit, division, segment or subsidiary of any
other business that engages in or otherwise competes with (or was organized for the purpose of engaging in or competing with) the business of providing behavioral healthcare and/or related services (provided that, this clause (ii) shall not be
construed to prohibit Executive from directly or indirectly owning any interest in, managing, controlling, participating in, consulting with, rendering services for, or in any manner engaging in any business activities with or for such business
generally and, for the avoidance of doubt, not specifically with respect to such unit, division, segment or subsidiary), in each case, within any geographical area in which Acadia and the Subsidiaries engage in such businesses; provided that
Executive shall not be subject to the restrictions set forth in this Section 7(a) if the Employment Period is terminated by the Company without Cause or by Executive with Good Reason and for so long as the Company is in
breach of its obligations under Section 4(b) and such breach is not the subject of a good faith dispute between the Company and Executive. For purposes of this Agreement, the term “participate in” shall include,
without limitation, having any direct or indirect interest in any Person, whether as a sole proprietor, owner, stockholder, partner, joint venturer, creditor or otherwise, or rendering any direct or indirect service or assistance to any individual,
corporation, partnership, joint venture and other business entity (whether as a director, officer, manager, supervisor, employee, agent, consultant or otherwise). Nothing herein shall prohibit Executive from being a passive owner of not more than 2%
of the outstanding stock of any class of a corporation which is publicly traded, so long as Executive has no active participation in the business of such corporation. 

  
 11 













 (b) Non-Solicit. During the Employment Period
and for a period thereafter of twenty-four (24) months (the “Nonsolicit Period”), Executive shall not directly or indirectly through another Person (other than on behalf of Acadia and the Subsidiaries) (i) induce or
attempt to induce any employee or independent contractor of Acadia or the Subsidiaries to leave the employ or services of Acadia or the Subsidiaries, or in any way willfully interfere with the relationship between Acadia and the Subsidiaries and any
employee or independent contractor thereof, (ii) hire or seek any business affiliation with any person who was an employee or independent contractor of Acadia or the Subsidiaries at any time during the twelve (12) months prior to the
Termination Date or (iii) willfully induce or attempt to induce any customer, supplier, licensee, licensor or other business relation of Acadia or any Subsidiary to cease doing business with Acadia or such Subsidiary or willfully interfere with
the relationship between any such customer, supplier, licensor or other business relation and Acadia or any Subsidiary. 
 (c) Non-Disparagement. Without limiting any other obligation of Executive pursuant to this Agreement, Executive hereby covenants and agrees that, except as may be required by applicable law, Executive shall
not make any statement, written or verbal, in any forum or media, or take any other action in disparagement of Acadia or any of its Subsidiaries, during the Employment Period and for a period of five (5) years thereafter (the “Non-Disparagement Period”). Without limiting any other obligation of Acadia and its Subsidiaries pursuant to this Agreement, Acadia hereby covenants and agrees that, except as may be required by applicable
law, Acadia shall direct its executive officers and members of its board of directors (and use commercially reasonable efforts to obtain compliance with such direction) not to make any statement, written or verbal, in any forum or media, or take any
other action in disparagement of Executive, during the Employment Period and the Non-Disparagement Period. This Section 7(c) will not be violated by (i) truthful statements required to be made by law
or legal process, or (ii) internal statements in connection with providing services to Acadia and its Subsidiaries. 
 (d)
Blue-Pencil. If, at the time of enforcement of Section 5 or 6 or this Section 7, a court shall hold that the duration, scope or area restrictions stated herein are unreasonable under
circumstances then existing, the parties agree that the maximum duration, scope or area reasonable under such circumstances shall be substituted for the stated duration, scope or area and that the court shall be allowed to revise the restrictions
contained herein to cover the maximum duration, scope and area permitted by law. Executive hereby acknowledges and represents that she has either consulted with independent legal counsel regarding her rights and obligations under this Agreement or
knowingly and voluntarily waived the opportunity to do so and that she fully understands the terms and conditions contained herein. 
 (e)
Additional Acknowledgments. Executive acknowledges that the provisions of Sections 5 and 6 and this Section 7 are in consideration of Executive’s employment with the Company and other good
and valuable consideration as set forth in this Agreement. In addition, Executive agrees and acknowledges that the restrictions contained in Sections 5 and 6 and this Section 7 do not preclude Executive from
earning a livelihood, nor do they unreasonably impose limitations on Executive’s ability to earn a living. In addition, Executive acknowledges (x) that the business of Acadia and the Subsidiaries will be conducted throughout the United
States and its 

  
 12 













 
territories and beyond, (y) notwithstanding the state of organization or principal office of Acadia or any of the Subsidiaries or facilities, or any of their respective executives or
employees (including Executive), it is expected that Acadia and the Subsidiaries will have business activities and have valuable business relationships within its industry throughout the United States and its territories and beyond, and (z) as
part of Executive’s responsibilities, Executive will be traveling throughout the United States and other jurisdictions where Acadia and the Subsidiaries conduct business during the Employment Period in furtherance of the Company’s business
relationships. Executive agrees and acknowledges that the potential harm to Acadia and the Subsidiaries of the non-enforcement of any provision of Sections 5 and 6 and this
Section 7 outweighs any potential harm to Executive of its enforcement by injunction or otherwise. Executive acknowledges that she has carefully read this Agreement and either consulted with legal counsel of
Executive’s choosing regarding its contents or knowingly and voluntarily waived the opportunity to do so, has given careful consideration to the restraints imposed upon Executive by this Agreement and is in full accord as to their necessity for
the reasonable and proper protection of confidential and proprietary information of Acadia and the Subsidiaries now existing or to be developed in the future. Executive expressly acknowledges and agrees that each and every restraint imposed by this
Agreement is reasonable with respect to subject matter, duration and geographical area. 
 (f) Specific Performance. In the event of
the breach or a threatened breach by Executive of any of the provisions of Section 5 or 6 or this Section 7, Acadia and the Subsidiaries would suffer irreparable harm and that money damages
would not be a sufficient remedy and, in addition and supplementary to other rights and remedies existing in its favor whether under this Agreement or under any other agreement, the Company shall be entitled to specific performance and/or injunctive
or other equitable relief from a court of competent jurisdiction in order to enforce or prevent any violations of the provisions hereof (without posting a bond or other security). In addition, in the event of an alleged breach or violation by
Executive of this Section 7, the Noncompete Period or the Nonsolicit Period, as applicable, shall be tolled until such breach or violation has been duly cured. 

8. Executive’s Representations. Executive hereby represents and warrants to the Company that (a) the execution,
delivery and performance of this Agreement by Executive do not and shall not conflict with, breach, violate or cause a default under any contract, agreement, instrument, order, judgment or decree to which Executive is a party or by which she is
bound, (b) except as previously disclosed to the Company in writing (a copy of each such agreement having been provided to the Company prior to the date hereof or being publicly available on EDGAR as of the date hereof), Executive is not a
party to or bound by any employment agreement, noncompete agreement or confidentiality agreement with any other person or entity, (c) except as previously disclosed to the Company in writing, Executive took nothing with her which belonged to
any former employer when Executive left her prior position and Executive has nothing that contains any information which belongs to any former employer, in either case which would reasonably be likely to result in any liability to Acadia or any
Subsidiary, and (d) upon the execution and delivery of this Agreement by the Company, this Agreement shall be the valid and binding obligation of Executive, enforceable in accordance with its terms. Executive hereby acknowledges and represents
that she has either consulted with independent legal counsel regarding her rights and obligations under this Agreement or knowingly and voluntarily waived the opportunity to do so and that she fully understands the terms and conditions contained
herein.

 17

all material investment or business opportunities of which she becomes aware that would customarily be brought to the attention of a board of directors and which are within the scope and investment objectives of Acadia or any of the Subsidiaries.

 23. Executive’s Cooperation. During the Employment Period and thereafter, Executive shall cooperate with Acadia

Executive being available to Acadia and the Subsidiaries upon reasonable notice for interviews and factual investigations, appearing at Acadia’s or any of the Subsidiaries’ request to give testimony without requiring service of a subpoena
or other legal process, volunteering Acadia and the Subsidiaries all pertinent information and turning over to Acadia and the Subsidiaries all relevant documents which are or may come into Executive’s possession, all at times and on schedules
that are reasonably consistent with Executive’s other permitted activities and commitments), all at Acadia’s or the Subsidiaries’ sole cost and expense. Any services requested by the Company under this Section 23 shall be
scheduled to not unreasonably interfere with Executive’s employment or personal obligations at the time. It is expressly agreed that the Company’s rights to avail itself of the advice and consultation services of Executive shall at all
times be exercised in a reasonable manner, that adequate notice shall be given to Executive in such events, and that non-compliance with any such request by Executive for good reason, including, but not
limited to, ill health or prior commitments, shall not constitute a breach or violation of this Agreement. 
 24. Delivery by Facsimile
or PDF. This Agreement, the agreements referred to herein, and each other agreement or instrument entered into in connection herewith or therewith or contemplated hereby or thereby, and any amendments hereto or thereto, to the extent signed and
delivered by means of a facsimile machine or electronic transmission in pdf, shall be treated in all manner and respects as an original agreement or instrument and shall be considered to have the same binding legal effect as if it were the original
signed version thereof delivered in person. At the request of any party hereto or to any such agreement or instrument, each other party hereto or thereto shall re-execute original forms thereof and deliver
them to all other parties. No party hereto or to any such agreement or instrument shall raise the use of a facsimile machine or electronic transmission in pdf to deliver a signature or the fact that any signature or agreement or instrument was

25. Indemnification and Directors and Officers Insurance. 

(a) During the Employment Period and for a period of six (6) years thereafter, the Company shall, to the fullest extent permitted under
applicable law, indemnify and hold harmless Executive on a basis no less favorable than members of the Board and in accordance with the bylaws of the Company and Acadia.

purchase and maintain, at its own expense, directors and officers liability insurance providing coverage for Executive in the same or greater amount as for members of the Board. 

  
 18 













 26. Legal Fees and Expenses. In the event any litigation or other court action,
arbitration or similar adjudicatory proceeding (a “Proceeding”) is commenced or threatened by any party hereto (the “Claiming Party”) to enforce its rights under this Agreement against any other party hereto (the
“Defending Party”), if the Defending Party is the prevailing party in such Proceeding, all fees, costs and expenses, including, without limitation, reasonable attorneys fees and court costs, incurred by the Defending Party in such
Proceeding, will be reimbursed by the Claiming Party, and, if the Claiming Party is the prevailing party in such Proceeding, all fees, costs and expenses, including, without limitation, reasonable attorneys fees and court costs, incurred by the
Claiming Party in such Proceeding, will be reimbursed by the Defending Party; provided that if the Defending Party prevails in part, and loses in part, in such Proceeding, the court, arbitrator or other adjudicator presiding over such Proceeding
shall award a reimbursement of the fees, costs and expenses incurred by the Claiming Party and the Defending Party on an equitable basis. For purposes of this Section26, and without limiting the generality of the foregoing, the Defending
Party will be deemed to have prevailed in any Proceeding if the Claiming Party commences or threatens such Proceeding and (i) the underlying claim(s) in such Proceeding are subsequently dropped or dismissed, or (ii) the Defending Party
defeats any such claim(s). 
 27. Acadia Guarantee. Acadia unconditionally guarantees and promises to pay and perform, upon
Executive’s demand following a default by the Company, any and all obligations of the Company from time to time owed to Executive under this Agreement, subject to any applicable cure period. Acadia further agrees that if the Company shall fail
to fulfill any of its obligations under this Agreement, Acadia will perform the same on demand as a principal obligor, and not as a surety. This is a continuing guarantee of the obligations and may not be revoked and shall not otherwise terminate
unless and until the obligations of the Company have been paid and performed in full. Acadia represents and warrants that it will receive a substantial benefit from Company’s employment of Executive, which employment gives rise to the
obligations of the Company under this Agreement. Acadia acknowledges that Executive would not execute this Agreement if it did not receive this guarantee.

 Exhibit B1 

GENERAL RELEASE 

I,                     , in
consideration of and subject to the performance by Acadia Management Company, Inc., a Delaware corporation (together with its subsidiaries, the “Company”), of its obligations under the Employment Agreement dated as of
January 19, 2021 (the “Agreement”), do hereby release and forever discharge as of the date hereof the Company and its respective affiliates and all present, former and future managers, directors, officers, employees, successors
and assigns of the Company and its affiliates and direct or indirect owners (collectively, the “Released Parties”) to the extent provided below (this “General Release”). The Released Parties are intended to be
third-party beneficiaries of this General Release, and this General Release may be enforced by each of them in accordance with the terms hereof in respect of the rights granted to such Released Parties hereunder. Terms used herein but not otherwise
defined shall have the meanings given to them in the Agreement. 
 1. I understand that any payments or benefits paid or granted to me under
Section 4 of the Agreement represent, in part, consideration for signing this General Release and are not salary, wages or benefits to which I was already entitled. I understand and agree that I will not receive certain of the payments and
benefits specified in Section 4, unless I execute this General Release and do not revoke this General Release within the time period permitted hereafter. Such payments and benefits will not be considered compensation for purposes of any
employee benefit plan, program, policy or arrangement maintained or hereafter established by the Company or its affiliates. 
 2. Except as
provided in paragraphs 5 and 6 below and except for the provisions of the Agreement which expressly survive the termination of my employment with the Company, I knowingly and voluntarily (for myself, my heirs, executors, administrators and assigns)
release and forever discharge the Company and the other Released Parties from any and all claims, suits, controversies, actions, causes of action, cross-claims, counter-claims, demands, debts, compensatory
damages, liquidated damages, punitive or exemplary damages, other damages, claims for costs and attorneys’ fees, or liabilities of any nature whatsoever in law and in equity, both past and present (through the date that this General Release
becomes effective and enforceable) and whether known or unknown, suspected, or claimed against the Company or any of the Released Parties which I, my spouse, or any of my heirs, executors, administrators or assigns, may have, including those that
arise out of or are connected with my employment with, or my separation or termination from, the Company (including, but not limited to, any allegation, claim or violation, arising under: Title VII of the Civil Rights Act of 1964, as amended; the
Civil Rights Act of 1991; the Age Discrimination in Employment Act of 1967, as amended (including the Older Workers Benefit Protection Act); the Equal Pay Act of 1963, as amended; the Americans with Disabilities Act of 1990; the Family and Medical
Leave Act of 1993; the Worker Adjustment Retraining and Notification Act; the Employee Retirement Income Security Act of 1974; any applicable Executive Order Programs; the Fair Labor Standards Act; or their state or local counterparts; or under any
other federal, state or local civil or human rights law, or under any other 
  

	1 	 Note to Draft: Subject to updates to the extent necessary for applicable governing law.




  
 22 













 
local, state, or federal law, regulation or ordinance; or under any public policy, contract or tort, or under common law; or arising under any policies, practices or procedures of the Company; or
any claim for wrongful discharge, breach of contract, infliction of emotional distress, defamation; or any claim for costs, fees, or other expenses, including attorneys’ fees incurred in these matters) (all of the foregoing collectively
referred to herein as the “Claims”). 
 3. The released claims described in paragraph 2 hereof include all such claims,
whether known or unknown by me. 
 4. I represent that I have made no assignment or transfer of any right, claim, demand, cause of action,
or other matter covered by paragraph 2 above. 
 5. I agree that this General Release does not waive or release any rights or claims that I
may have under the Age Discrimination in Employment Act of 1967 which arise after the date I execute this General Release. I acknowledge and agree that my separation from employment with the Company in compliance with the terms of the Agreement
shall not serve as the basis for any claim or action (including, without limitation, any claim under the Age Discrimination in Employment Act of 1967). 

6. I agree that I hereby waive all rights to sue or obtain equitable, remedial or punitive relief from any or all Released Parties of any kind
whatsoever in respect of any Claim, including, without limitation, reinstatement, back pay, front pay, and any form of injunctive relief. Notwithstanding the above, I further acknowledge that I am not waiving and am not being required to waive any
right that cannot be waived under law, including the right to file an administrative charge or participate in an administrative investigation or proceeding; provided, however, that I disclaim and waive any right to share or participate
in any monetary award resulting from the prosecution of such charge or investigation or proceeding. Additionally, I am not waiving (and nothing set forth herein shall be deemed a release of) (i) any right to any earned and accrued salary,
vacation, benefits, expense reimbursements, or any severance benefits to which I am entitled under the Agreement, (ii) any claim relating to directors’ and officers’ liability insurance coverage or any right of indemnification under
the Company’s organizational documents, applicable law or otherwise, including, without limitation, Sections 25 and 26 of the Agreement and/or (iii) my rights as an equity or security holder in the Company, Acadia or their affiliates.

 7. In signing this General Release, I acknowledge and intend that it shall be effective as a bar to each and every one of the Claims
hereinabove mentioned or implied. I expressly consent that this General Release shall be given full force and effect according to each and all of its express terms and provisions, including those relating to unknown and unsuspected Claims
(notwithstanding any state or local statute that expressly limits the effectiveness of a general release of unknown, unsuspected and unanticipated Claims), if any, as well as those relating to any other Claims hereinabove mentioned or implied. I
acknowledge and agree that this waiver is an essential and material term of this General Release and that without such waiver the Company would not have agreed to the terms of the Agreement. I further agree that in the event I should bring a Claim
seeking damages against the Company, or in the event I should seek to recover against the Company in any Claim brought by a governmental agency on my behalf, this General Release shall serve as a complete defense to such Claims to the maximum extent
permitted by law. I further agree that I am not aware of any pending claim of the type described in paragraph 2 above as of the execution of this General Release. 

  
 23 













 8. I agree that neither this General Release, nor the furnishing of the consideration for
this General Release, shall be deemed or construed at any time to be an admission by the Company, any Released Party or myself of any improper or unlawful conduct. 

9. I agree that if I violate this General Release by suing the Company or the other Released Parties, I will pay all costs and expenses of
defending against the suit incurred by the Released Parties, including reasonable attorneys’ fees. 
 10. Any non-disclosure provision in this General Release does not prohibit or restrict me (or my attorney) from responding to any inquiry about this General Release or its underlying facts and circumstances by the
Securities and Exchange Commission (SEC), the Financial Industry Regulatory Authority (FINRA), any other self-regulatory organization or any governmental entity. 

11. I hereby acknowledge that Sections 4 through 27 (other than Section 22) of the Agreement shall survive my execution of this General
Release. 
 12. I represent that I am not aware of any claim by me other than the claims that are released by this General Release. I
