As previously disclosed, on January 20, 2026 (the “Effective Date”), Acadia Healthcare Company, Inc. (“Acadia” or the “Company”) announced that Christopher H. Hunter had departed from his role as Chief Executive Officer of Acadia, effective as of the Effective Date. In connection with his departure from Acadia, Mr. Hunter also resigned from Acadia’s Board of Directors, effective as of the Effective Date.

In connection with Mr. Hunter’s departure from his role as Chief Executive Officer of Acadia, Mr. Hunter and Acadia Management Company, LLC, a Delaware limited liability company, entered into a separation and release agreement, dated as of the Effective Date (the “Separation Agreement”).

Pursuant to the Separation Agreement, Mr. Hunter will receive the following separation benefits: (i) he will remain eligible to earn his annual bonus for the 2025 calendar year (with such amount, if any, to be determined and paid in accordance with his employment agreement at the same time such annual bonuses are paid to other employees of the Company); (ii) an amount equal to 1.5 times the sum of (x) his base salary and (y) his target annual bonus for the 2025 calendar year, payable in substantially equal installments for 18 months following the Effective Date; (iii) an amount equal to the after-tax cost of premiums for continued health and dental insurance under the Company’s group health plans for him and his covered dependents for 18 months following the Effective Date, payable in monthly installments over such 18-month period; (iv) a lump sum cash payment equal to $1,785,000 in respect of his cash retention bonus pursuant to that certain Retention Bonus Agreement entered into by and between Mr. Hunter and the Company, dated as of January 14, 2025; and (v) a prorated portion of his outstanding performance-based restricted stock units (“PSUs”), determined based on the actual number of days elapsed during the applicable performance period on or before the Effective Date, will remain outstanding and eligible to vest at the end of the applicable performance period based on actual achievement of the applicable performance conditions. Further, except with respect to the treatment of the foregoing prorated PSUs, any unvested equity or equity-based awards held by Mr. Hunter as of the Effective Date were immediately forfeited for no consideration as of the Effective Date.

Mr. Hunter’s receipt of the aforementioned separation benefits is conditioned upon the effectiveness of a general release of claims in favor of Acadia (and certain of its affiliates and related parties including, without limitation, Acadia Management Company, LLC) that is included in the Separation Agreement, as well as Mr. Hunter’s continued compliance with restrictive covenants.
