Section 3. Classes of Directors.

Subject to the terms of any series of Preferred Stock, the directors shall be elected by a plurality of the votes of the shares present in person or represented by proxy at the meeting and entitled to vote in the election of directors; provided that, whenever the holders of one or more classes or series of capital stock of the Corporation are entitled to elect, separated as a class, one or more directors pursuant to the provisions of this Certificate of Incorporation (including, but not limited to, any duly authorized certificate of designation), such directors shall be elected by a plurality of the votes of such classes or series present in person or represented by proxy at the meeting and entitled to vote in the election of such directors.

Notwithstanding the foregoing, to the fullest extent permitted by law, until such date as Waud Capital Partners, L.L.C. and its affiliates (collectively, the “WCP Investors”) ceases to hold at least 17.5% of the outstanding Common Stock of the Corporation (such date, the “Trigger Date”), upon any vacancy in the Board of Directors for any reason of a director designated by a person or persons in accordance with the terms of the Stockholders Agreement to be entered into by and between the Corporation and the Stockholders

3

party thereto on or about the Effective Time (as amended or restated from time to time, the “Stockholders Agreement”), the resulting vacancy on the Board of Directors shall be filled by a representative designated by the person(s) entitled to designate such director pursuant to the Stockholders Agreement. Prior to the Effective Time, a director chosen to fill a vacancy or a position resulting from an increase in the number of directors shall hold office until his or her successor is elected and qualified, or until his or her earlier death, resignation or removal.

After the Effective Time, a director chosen to fill a position resulting from an increase in the number of directors shall hold office until the next election of the class for which such director shall have been chosen and until his or her successor is elected and qualified, or until his or her earlier death, resignation or removal. No decrease in the authorized number of directors shall shorten the term of any incumbent director.

Section 6. Removal of Directors. Subject to the rights of the holders of any series of Preferred Stock then outstanding, to the fullest extent permitted by law, (i) until the Trigger Date, (a) a director designated by person(s) entitled to designate such director in accordance with the Stockholders Agreement may be removed at any time, either for or without cause, only upon either (x) the affirmative vote of the holders of eighty percent (80%) of the voting power of the capital stock of the Corporation outstanding and entitled to vote thereon or (y) if such director is being removed at the request of the person(s) entitled to designate such director in accordance with the Stockholders Agreement, by the affirmative vote of the holders of a majority of the voting power of the stock outstanding and entitled to vote thereon and (b) a director not designated by person(s) entitled to designate such director in accordance with the Stockholders Agreement may be removed from office only for cause and only by the affirmative vote of the holders of at least a majority of the voting power of the capital stock of the Corporation outstanding and entitled to vote thereon; and (ii) from and after the Trigger Date, a director may be removed from office only for cause and only by the affirmative vote of the holders of at least a majority of the voting power of the capital stock of the Corporation outstanding and entitled to vote thereon.

In furtherance and not in limitation of the powers conferred upon it by the laws of the State of Delaware, the Board of Directors shall have the power to adopt, amend, alter or repeal the Corporation’s Bylaws. In addition to any other vote required by law, the affirmative vote of a majority of the directors then in office shall be required to adopt, amend, alter or repeal the Corporation’s Bylaws.

Notwithstanding the foregoing, nothing herein shall preclude Executive from (i) serving, with the prior written consent of the Board (not to be unreasonably withheld), 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) or (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);

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 Executive’s 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 $515,000 per annum, subject to increase by the Board or Acadia’s Compensation Committee (the “Compensation Committee”) in its sole discretion on an annual basis (as adjusted 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) Bonus. In addition to the Base Salary, during each calendar year of the Employment Period beginning with the year ending December 31, 2024, Executive will be eligible to earn a target annual cash bonus of 85% of the Base Salary and up to a maximum cash bonus equal to two (2) times the target annual cash bonus for such year, 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. Notwithstanding the foregoing, Executive’s Annual Bonus for the 2024 calendar year will be equitably blended based on Executive’s target bonus in effect immediately before the Start Date and that in effect for the balance of the performance year. 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.

(c) Long-Term Incentive Compensation. Executive shall be eligible to receive annual grants of long-term incentive awards in amounts and on terms and conditions comparable to Acadia’s other senior executives as determined by the Compensation Committee.

(d) Business Expenses. During the Employment Period, the Company shall reimburse Executive bi-weekly in accordance with the Company’s customary payroll practices for all reasonable out-of-pocket business expenses incurred by Executive in the course of performing Executive’s duties and responsibilities under this Agreement that are consistent with the Company’s policies in effect from time to time with respect to travel, lodging, meals, entertainment and other business expenses, subject to the Company’s requirements with respect to reporting and documentation of such expenses.

(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 Executive’s sole discretion in all of the Company’s employee benefit programs for which senior executive employees of the Company are generally eligible.

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 “Termination Date.”

(iii) an amount equal to one (1) times the target annual cash bonus amount to which Executive would be entitled under Section 3(b) with respect to the calendar year in which the Termination Date occurs, determined as if Executive, Acadia and the Subsidiaries have achieved all of the performance objectives specified in Executive’s bonus plan for such year at the target level, whether or not such objectives actually have been achieved as of the Termination Date (payable in a lump sum within ten (10) business days after the Termination Date);

(viii) all equity and equity-based awards granted to Executive during the Employment Period (the “Equity Awards”) shall be treated as set forth below: (A) the Equity Awards subject to time-based vesting requirements will fully vest on the Termination Date; and (B) the Equity Awards subject to performance-based vesting requirements will remain outstanding and eligible to vest based on actual achievement of the applicable performance conditions, subject to the terms and conditions (other than any term or condition requiring continued employment) set forth in the applicable award agreement and/or governing documentation.

Notwithstanding the foregoing, Executive shall not be entitled to receive the benefits provided for in Sections 4(b)(ii) – 4(b)(viii) above unless and until Executive signs and delivers and does not revoke the General Release substantially in the form attached hereto as Exhibit B; and provided further that Executive has not breached any of the provisions of Sections 5, 6 and 7 hereof.

(iii) payment in respect of any unused paid time off and sick pay of Executive in such amounts as have accrued as of the Termination Date in accordance with the Company’s policies with respect thereto as in effect during the Employment Period, and reimbursement of any business expenses incurred by Executive but not reimbursed prior to the Termination Date in accordance with and reimbursable under the terms of the Company’s policies with respect thereto as in effect on the Termination Date (in each case, payable in a lump sum within ten (10) business days after the Termination Date);

4

(iv) 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 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) payment of the Annual Bonus under Section 3(b) for the prior year, to the extent not previously paid.

In addition, if the Employment Period is terminated due to Executive’s becoming Disabled (but, for the avoidance of doubt, not due to Executive’s death), then Executive (or Executive’s 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 the Employment Period 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) payment of the Annual Bonus for the prior year to the extent not paid.

(e) Continuation of Benefits. Upon any termination of employment, whether voluntary or otherwise, Executive shall have the option to elect health insurance coverage for Executive, Executive’s spouse and Executive’s 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 earliest 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

5

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.

(f) 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.

(g) 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.

(h) Section 409A Compliance.

(i) The intent of the parties is that payments and benefits under this Agreement comply with Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”) and the regulations and guidance promulgated thereunder (collectively “Code Section 409A”) and, accordingly, to the maximum extent permitted, this Agreement shall be interpreted and administered 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.

(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.

6

(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 (a) the expiration of the six (6)-month period measured from the date of such “separation from service” of Executive and (b) 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 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 the Delay Period.

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 at any time thereafter, Executive shall not disclose to any unauthorized person or use for Executive’s own account any of such

7

Confidential Information, whether or not developed by Executive, without the Board’s prior written consent, unless and to the extent that any Confidential Information (1) 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, (2) 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 (3) 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 Executive’s employment with the Company, Executive believes Executive 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.

(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), 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 Executive’s 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 will be interpreted so as to impede Executive (or any other individual) from (i) making any disclosure of relevant and necessary information or documents in any action, investigation, or proceeding relating to this Agreement, or as required by law or legal process, including with respect to possible violations of law, (ii) participating, cooperating, or testifying in any action, investigation, or proceeding with, or providing information to, any governmental agency, legislative body or any self-regulatory organization, including, but not limited to, the Department of Justice, the Securities and Exchange Commission, the Congress, and any agency Inspector General, (iii) accepting any U.S. Securities and Exchange Commission Awards, or (iv) making other disclosures under the whistleblower provisions of federal law or regulation. In addition, nothing in this Agreement or any other agreement or Company policy prohibits or restricts Executive from initiating communications with, or responding to any inquiry from, any administrative, governmental, regulatory or supervisory authority regarding any good faith concerns about possible violations of law or regulation. Executive does not need the prior authorization of the Company to make any such reports or disclosures and Executive will not be required to notify the Company that such reports or disclosures have been made.

8

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 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 Executive’s 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 Executive’s employment with the Company, Executive 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 Executive’s 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 twelve (12) months (the “Noncompete Period”), Executive 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 the business of providing behavioral healthcare and/or related services 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,

9

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.

(b) Non-Solicit. During the Employment Period and for a period thereafter of twelve (12) 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 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) 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 interfere with the relationship between any such customer, supplier, licensor or other business relation and Acadia or any Subsidiary; provided that Executive shall not be subject to the restrictions set forth in this Section 7(b) 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.

(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”).

(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 Executive has either consulted with independent legal counsel regarding Executive’s rights and obligations under this Agreement or knowingly and voluntarily waived the opportunity to do so and that Executive 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

10

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 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 Executive 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 Executive 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 Effective Date or being publicly available on EDGAR as of the Effective Date), 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 Executive which belonged to any former employer when Executive left Executive’s 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 Executive has either consulted with independent legal counsel regarding Executive’s rights and obligations under this Agreement or knowingly and voluntarily waived the opportunity to do so and that Executive fully understands the terms and conditions contained herein.

11

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.

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.

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.

BY SIGNING THIS GENERAL RELEASE, I REPRESENT AND AGREE THAT:

Exhibit 10.2

SEPARATION AND CONSULTING AGREEMENT

This Separation Agreement (this “Agreement”), dated May 23, 2024, is effective as of the “Effective Date” (as defined below), between Acadia Management Company, Inc. (the “Company”) and John Hollinsworth (“Employee” and with the Company, collectively, the “Parties”).

W I T N E S S E T H

WHEREAS, Employee is employed by the Company pursuant to an Employment Agreement, dated July 31, 2019, between the Company and Employee (the “Employment Agreement”);

WHEREAS, Employee has notified the Company that Employee intends to voluntarily resign from his employment with the Company and position as Executive Vice President of Operations of the Company on June 30, 2024, after which date, Employee shall provide Consulting Advisory Service (as defined below) to the Company as provided under this Agreement; and

WHEREAS, the Parties wish to resolve all matters that Employee may have related to Employee’s employment and the termination of Employee’s employment and consulting services.

NOW, THEREFORE, in consideration of the premises and the releases, representations, covenants and obligations herein contained, the Parties, intending to be legally bound, hereby agree as follows:

1.  Cessation of Employment Relationship; Final Pay; COBRA.

(a) Employee’s employment with the Company shall cease effective as of June 30, 2024, or such earlier date as determined by the Company in its sole discretion (the “Employment Separation Date”), though until then Employee agrees the Company may reduce or eliminate some or all of Employee’s duties, authorities and responsibilities in such manner and at such time or times as it determines to be appropriate in its sole discretion without constituting a constructive termination or breach of any agreement with Employee. Employee and the Company agree that upon the Employment Separation Date, Employee shall promptly resign, and shall be deemed to have resigned from all other officer, director and employment positions that Employee held at or through the Company, and any of its parents, subsidiaries or affiliates, and Employee agrees to promptly execute such additional documentation as requested by the Company to effectuate the foregoing. The Employment Separation Date will be the termination date of Employee’s employment for purposes of Employee’s active participation in and coverage under all benefit plans and programs sponsored by or through the Company or its affiliates, except as otherwise required by applicable law. For the avoidance of doubt, the parties acknowledge that Section 4(f) of the Employment Agreement regarding Employee’s continuation of benefits following any termination of employment shall survive the execution of this Agreement and continue in full force and effect.

(b) Regardless of whether Employee executes this Agreement, the Company shall timely pay to Employee, minus applicable withholdings and authorized or required deductions: (i) all earned, but unpaid, wages and accrued, but unused, vacation time earned in accordance with applicable law and Company policy through the Employment Separation Date; (ii) any unpaid expenses or other reimbursements, due to Employee under the Company’s policies, provided that Employee must submit for reimbursement any outstanding business-related expenses within ten (10) days following the Employment Separation Date; and (iii) any amounts payable under the Company’s applicable employee benefits plans and programs in accordance with their terms, including, without limitation, under the Company’s Nonqualified Deferred Compensation Plan.

(c) Employee will receive under separate cover information regarding Employee’s rights under the Consolidated Omnibus Budget Reconciliation Act and, if applicable, any state continuation coverage laws (collectively, “COBRA”). Employee acknowledges that Employee should review the COBRA notice and election forms carefully to understand Employee’s rights and obligations to make timely elections, provide timely notification and make timely premium payments. For the avoidance of doubt, the parties acknowledge that Section 4(f) of the Employment Agreement regarding Employee’s continuation of benefits following any termination of employment shall survive the execution of this Agreement and continue in full force and effect.

(d) For the avoidance of doubt, all outstanding equity awards held by Employee shall be treated in accordance with the terms and conditions of the Acadia Healthcare Company Inc., Incentive Compensation Plan and the applicable award agreement. Employee’s separation from employment on the Employment Separation Date shall constitute a “retirement” for purposes of all outstanding performance-vesting restricted stock unit equity awards held by Employee pursuant the terms of the applicable award agreements.

2. Consulting Advisory Services. During the period following the Employment Separation Date and ending on December 31, 2024 or such prior date as determined by the Company in its sole discretion upon notice to Employee (the “Consulting Advisory Period”), Employee shall make himself available to provide transition advisory services as reasonably requested by the any of the Company’s executive officers, the Company’s Chief Executive Officer or the Board of Acadia Healthcare Company, Inc. (the “Consulting Advisory Services”). Employee will provide the Consulting Advisory Services for no more than 30 hours per month. During the Consulting Advisory Period, in consideration of Employee’s Consulting Advisory Services, continued compliance with the terms and conditions of this Agreement (including, without limitation, Section 5), the discharge of Employee’s duties as Executive Vice President of Operations, and the timely execution of the ADEA Release in accordance with this Agreement, Employee shall be paid $10,000.00 (ten thousand dollars) per month, in accordance with the Company’s standard payroll practices. With respect to services rendered during the Consulting Advisory Period, Employee’s relationship to the Company will only be that of any independent contractor and, as an independent contractor, Employee agrees to pay in a timely manner all social security and other payroll taxes relating to such compensation. The sole compensation Employee will receive for services during the Consulting Advisory Period is set forth in this Section 2 and Section 3 below.

3. Separation Payment. Provided that Employee complies with this Agreement and the “ADEA Release” (as defined below) becomes effective pursuant to its terms, Employee shall remain eligible to earn a prorated portion of Employee’s annual bonus for the 2024 calendar year based on the number of calendar days between January 1, 2024 and the Employment Separation Date, such amount, if any, to be determined and paid in accordance with Section 3(c) of the Employment Agreement at the same time such annual bonuses are paid to other employees of the Company, less all applicable withholdings and authorized or required deductions. The payments under this Section 3 are not earnings or wages under any Company 401(k) plan.

4. Confidentiality. Subject to Section 12 below, Employee agrees that the terms and conditions of this Agreement; the circumstances of Employee’s separation from the Company; all nonpublic, confidential, proprietary and trade secret information that Employee obtained or developed as result of Employee’s employment with the Company; and any events relating to the Company and/or the Company’s employees that occurred during Employee’s employment with the Company are strictly confidential, except that Employee may disclose the terms and conditions to Employee’s attorneys, accountants, tax consultants, state and federal tax authorities or as may otherwise be required by law (provided such parties are instructed to comply with this section).

(b) Notwithstanding anything in this Agreement to the contrary, Employee’s release of Claims under the Age Discrimination in Employment Act, as amended (the “ADEA Release”) shall only become effective (i) with respect to Employee’s release of Claims under the ADEA as of the Effective Date upon: (x) Employee’s initial separate signature set forth on the signature page of this Agreement reflecting Employee’s assent to Employee’s release of Claims under the ADEA as of the Effective Date and (y) Employee not revoking such execution by the seventh (7th) calendar day following such execution; and (ii) with respect to Employee’s release of Claims under the ADEA as of the date that Employee re-executes this Agreement upon: (x) Employee’s second separate signature set forth on the signature page of this Agreement reflecting Employee’s assent to Employee’s release of Claims under the ADEA as of the date of such re-execution and (y) the occurrence of the ADEA Release Effective Date (as defined below).

(c) Employee represents and agrees that Employee has not, by himself/herself or on Employee’s behalf, instituted, prosecuted, filed, or processed any litigation, Claims or proceedings against the Company or any Released Parties, nor has Employee encouraged or assisted anyone to institute, prosecute, file, or process any litigation, Claims or proceedings against the Company or any Released Parties. Nothing in this Section 6 shall release or impair (i) any Claim or right that may arise after the date that Employee executes or re-executes (as applicable) this Agreement; (ii) any right to any earned and accrued base salary, vacation or benefits or incurred but unreimbursed business expense reimbursements or any severance or other benefits to which Employee is entitled under this Agreement (including, without limitation, Section 1 of this Agreement, which it is acknowledged Employee is entitled to receive as provided herein), (iii) any rights to vested ERISA benefits, as well as Employee’s rights as an equity or security holder in the Company or its affiliates; (iv) any Claim or right Employee may have pursuant to indemnification, advancement, defense, or reimbursement pursuant to any applicable D&O policies, any similar insurance policies, applicable law or otherwise; and (v) any Claim which by Federal, state or local law cannot be waived.

(d) Employee understands that Employee may later discover Claims or facts that may be different than, or in addition to, those which Employee now knows or believes to exist with regards to the subject matter of this Agreement, and which, if known at the time of executing or re-executing (as applicable) this Agreement, may have materially affected this Agreement or Employee’s decision to enter into it. Employee hereby waives any right or Claim that might arise as a result of such different or additional Claims or facts.

4

(e) Employee represents that Employee has made no assignment or transfer of any right or Claim covered by this Section 6 and that Employee further agrees that Employee is not aware of any such right or Claim covered by this Section 6.

(f) Employee understands, acknowledges, and agrees that any amounts paid to him in accordance with Section 3 of this Agreement exceed what Employee is otherwise entitled to receive upon separation from employment due to Employee’s voluntary resignation, and that these benefits are being given as consideration in exchange for executing this Agreement, including the ADEA Release contained in it. Employee understands that he will not receive any payments specified in Section 3 unless Employee executes this Agreement including the ADEA Release contained in it, re-executes this Agreement for purposes of the ADEA Release (including upon expiration of the Consulting Advisory Period), and does not revoke the execution and re-execution of the ADEA Release within the time period permitted hereafter and thereafter. Employee acknowledges and agrees that, except as expressly set forth under this Agreement, Employee is not entitled to receive any additional compensation, bonus, equity compensation, payment in lieu of any paid time off, equity awards, severance payments or other payments or benefits of any kind from the Company or its parents, subsidiaries or its affiliates or with respect to Employee’s employment with the Company or any of its parents, subsidiaries and affiliates, including, without limitation, any payments of any kind under the Employment Agreement.

(g) In signing or re-signing (as applicable) the ADEA Release, Employee acknowledges and intends that it will be effective as a bar to each and every one of the released Claims hereinabove mentioned or implied. Employee expressly consents that the ADEA Release will be given full force and effect according to each and all of its express terms and provisions, including those relating to unknown and unsuspected released Claims (not withstanding 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 released Claims hereinabove mentioned or implied. Employee acknowledges and agrees that this waiver is an essential and material term of the ADEA Release and that without such waiver the Company would not have agreed to the terms of this Agreement. Employee further agrees that in the event Employee should seek to recover against the Company in any released Claim brought by a governmental agency on Employee’s behalf, the ADEA Release will serve as a complete defense to such released Claim to the maximum extent permitted by law. Employee further agrees that he is not aware of any pending claim of the type described in Section 6(a) above as of the execution and re-execution (as applicable) of the ADEA Release.

7. No Cooperation with Non-Governmental Third Parties.

Employee acknowledges and agrees that, other than as expressly approved by the Company and necessary for the provision of the Consulting Advisory Services, Employee has returned, or will return within two (2) days after the Employment Separation Date, all Company property and non-public, confidential, proprietary and/or trade secret information in Employee’s custody, possession or control, in any form whatsoever, including without limitation, equipment, telephones, smart phones, work-related passwords; PDAs, laptops, credit cards, keys, access cards, identification cards, security devices, network access devices, pagers, confidential or proprietary information, documents, manuals, reports, books, compilations, work product, e-mail messages, recordings, tapes, removable storage devices, hard drives, computers and computer discs, files and data (collectively, “Company Property”), which Employee prepared or obtained during the course of Employee’s employment with the Company. If Employee discovers any property of the Company or non-public, confidential, proprietary and/or trade secret information in Employee’s possession after the Effective Date, Employee shall promptly return such property to the Company or, at the instruction of the Company, destroy such property or information. Notwithstanding the foregoing, Employee further acknowledges and agrees that Employee will return within two (2) days after the expiration of the Consulting Advisory Period any Company Property obtained during the Consulting Advisory Period or retained for use during the Consulting Advisory Period with express approval by the Company.

9. No Admission of Liability; No Prevailing Party. The Parties agree that this Agreement is not to be construed as an admission of any wrongdoing or liability on the part of the Parties under any statute or otherwise, but that on the contrary, any such wrongdoing or liability is expressly denied by the Parties. The Parties agree that neither this Agreement nor the negotiations in pursuance thereof shall be construed or interpreted to render the Parties a prevailing party for any reason, including but not limited to an award of attorney’s fees, expenses or costs under any statute or otherwise.

10. Voluntary Execution. Employee acknowledges, certifies and agrees that: (a) Employee has carefully read this Agreement and fully understands all of its terms; (b) Employee had a reasonable amount of time to consider Employee’s decision to execute or re-execute (as applicable) this Agreement; (c) in executing or re-executing (as applicable) this Agreement Employee does not rely and has not relied upon any representation or statement made by any of the Company’s agents, representatives, or attorneys with regard to the subject matter, basis, or effect of the Agreement; and (d) that Employee enters into this Agreement voluntarily, of Employee’s own free will, without any duress and with knowledge of its meaning and effect in exchange for good and valuable consideration to which Employee would not be entitled in the absence of executing or re-executing (as applicable) this Agreement and not revoking the ADEA Release. Employee acknowledges that the Company has advised Employee to consult with an attorney prior to executing or re-executing (as applicable) this Agreement and that Employee has had an opportunity to consult with Employee’s counsel.

11. Review Period. Employee has been given twenty-one (21) days from the date of Employee’s receipt of this Agreement to consider the terms of this Agreement, although Employee may sign it at any time sooner; provided, that Employee may not re-execute the ADEA Release until the expiration of the Consulting Advisory Period. The Parties agree that any revisions or modifications to this Agreement, whether material or immaterial, will not and did not restart this time period. The first date upon which Employee and the Company have signed this Agreement and the Company has received Employee’s signature, shall be the “Effective Date”. Employee has seven (7) calendar days after the date on which Employee initially executes this Agreement for purposes of the ADEA Release to revoke Employee’s consent to the ADEA Release. If

Employee does not sign this Agreement for purposes of the ADEA Release or if Employee revokes Employee’s first execution of this Agreement for purposes of the ADEA Release, the ADEA Release shall be null and void and the “ADEA Release Effective Date” (as defined below) shall not occur. Provided that Employee does not revoke Employee’s first execution of this Agreement for purposes of the ADEA Release within such seven (7) day revocation period, this ADEA Release will become effective on the eighth (8^th) calendar day after the date on which Employee signs this Agreement for purposes of the ADEA Release. Employee’s re-execution of the ADEA Release advances the ADEA Release to the date of such re-execution. After such re-execution, Employee has seven (7) calendar days to revoke Employee’s consent to the advancement of the ADEA Release to the date of such re-execution. Provided that Employee does not revoke Employee’s re-execution of the ADEA Release within such seven (7) day revocation period, the ADEA Release will advance to the date of such re-execution effective on the eighth (8^th) calendar day after the date on which Employee re-executes the ADEA Release (the “ADEA Release Effective Date”). Employee must also re-execute the ADEA release on, or within 21 days after, the expiration of the Consulting Advisory Period to remain eligible to receive the benefits hereunder and must not revoke Employee’s re-execution of such ADEA Release within 7 days thereafter. If Employee does not re-execute the ADEA Release or if Employee revokes Employee’s re-execution of the ADEA Release, the Company’s obligations under Section 3 of this Agreement shall be null and void; however, the ADEA Release will remain in full force and effect through the Effective Date. For purposes of the foregoing, any revocation must be in writing and must be emailed to Chris Hunter at Chris.Hunter@acadiahealthcare.com, and notice of such revocation must be received within the applicable seven (7) calendar days referenced above.

12. Permitted Disclosures. Nothing in this Agreement or any other agreement between the Parties or any other policies of the Company or its affiliates shall prohibit or restrict Employee or Employee’s attorneys from: (a) making any disclosure of relevant and necessary information or documents in any action, investigation, or proceeding relating to this Agreement, or as required by law or legal process, including with respect to possible violations of law; (b) participating, cooperating, or testifying in any action, investigation, or proceeding with, or providing information to, any governmental agency or legislative body, any self-regulatory organization, and/or pursuant to the Sarbanes-Oxley Act; or (c) accepting any U.S. Securities and Exchange Commission awards or awards under other whistleblower laws that cannot be waived by law. In addition, nothing in this Agreement or any other agreement between the Parties or any other policies of the Company or its affiliates prohibits or restricts Employee from initiating communications with, or responding to any inquiry from, any regulatory or supervisory authority regarding any good faith concerns about possible violations of law or regulation. Pursuant to 18 U.S.C. § 1833(b), Employee will not be held criminally or civilly liable under any Federal or state trade secret law for the disclosure of a trade secret of the Company or its affiliates that (i) is made (x) in confidence to a Federal, state, or local government official, either directly or indirectly, or to Employee’s attorney and (y) solely for the purpose of reporting or investigating a suspected violation of law; or (ii) is made in a complaint or other document that is filed under seal in a lawsuit or other proceeding. If Employee files a lawsuit for retaliation by the Company for reporting a suspected violation of law, Employee may disclose the trade secret to Employee’s attorney and use the trade secret information in the court proceeding, if Employee files any document containing the trade secret under seal, and does not disclose the trade secret, except pursuant to court order. Nothing in this Agreement or any other agreement between the Parties or any other policies of the Company or its affiliates is intended to conflict with 18 U.S.C. § 1833(b) or create liability for disclosures of trade secrets that are expressly allowed by such section.

13. Successors and Assigns; Third-Party Beneficiaries. The Parties agree that this Agreement shall inure to the benefit of the personal representatives, heirs, executors, and administrators of Employee. This Agreement may not be assigned by Employee. The Company may freely assign all rights and obligations of this Agreement to any affiliate or successor (including to a purchaser of assets). The Released Parties are expressly intended to be third-party beneficiaries of this Agreement and it may be enforced by each of them.

14. No Oral Modifications. This Agreement shall not be modified except in writing signed by Employee and an authorized representative of the Company.

15. Severability. If any terms of the above provisions of this Agreement are found null, void or inoperative, for any reason, the remaining provisions will remain in full force and effect. The language of all parts of this Agreement shall in all cases be construed as a whole, according to its fair meaning, and not strictly for or against either of the Parties.

16. Counterparts. This Agreement may be executed in counterparts, each of which will be deemed an original but all of which together will constitute one and the same instrument. An originally executed version of this Agreement that is scanned as an image file (e.g., Adobe PDF, TIF, etc.) and then delivered by one Party to the other Party via electronic mail as evidence of signature, shall, for all purposes hereof, be deemed an original signature.

17. Governing Law; Jurisdiction; Waiver of Jury Trial. The Parties agree that this Agreement and the rights and obligations hereunder shall be governed by, and construed in accordance with, the laws of the State of Delaware regardless of any principles of conflicts of laws or choice of laws of any jurisdiction. The Parties agree that any action between Employee and the Company shall be resolved exclusively in a federal or state court in Tennessee, and the Company and Employee hereby consent to such jurisdiction and waive any objection to the jurisdiction of any such court. As a specifically bargained for inducement for each of the Parties to enter into this Agreement, Employee and the Company (after having the opportunity to consult with counsel) hereby waive trial by jury as to any and all litigation arising out of and/or relating to this Agreement.

18. Entire Agreement. This Agreement and the Employment Agreement constitute the complete and entire agreement and understanding of the Parties, and supersede in their entirety any and all prior understandings, negotiations, commitments, obligations and/or agreements, whether written or oral, between the Parties. The Parties represent that, in executing or re-executing (as applicable) this Agreement, each Party has not relied upon any representation or statement made by the other Party, other than those set forth in this Agreement, with regard to the subject matter, basis or effect of this Agreement.
