EXECUTION VERSION

ROLLOVER AGREEMENT

ROLLOVER AGREEMENT, dated as of March 2, 2026 (this “Agreement”), among Stallion Intermediate Corporation, a Delaware corporation (“Parent”), and the undersigned (the “Investor”). Capitalized terms used in this Agreement but not defined herein shall have the meanings set forth in the Merger Agreement (as defined below).

WHEREAS, Parent has entered into that certain Agreement and Plan of Merger, dated as of the date hereof (as may be amended, modified or supplemented from time to time, the “Merger Agreement”), with Stallion Merger Sub Corporation, a Delaware corporation and wholly-owned direct subsidiary of Parent (“Merger Sub”), and Select Medical Holdings Corporation, a Delaware corporation (the “Company”), pursuant to which (a) at the Effective Time, Merger Sub shall be merged with and into the Company, (b) the separate corporate existence of Merger Sub shall thereupon cease and (c) the Company shall continue as the surviving corporation and a wholly owned Subsidiary of Parent (the “Merger” and, together with the other transactions contemplated by the Merger Agreement and this Agreement, collectively, the “Transactions”), upon the terms and subject to the conditions set forth therein;

WHEREAS, as of the date hereof, the Investor beneficially owns, directly or indirectly, 280,415 shares of the Company’s common stock, par value $0.001 per share (the “Company Shares” and together with any New Shares (as defined herein), the “Subject Securities”);

WHEREAS, on the terms and subject to the conditions of this Agreement, the Investor desires, at the Contribution Closing, to contribute to Parent all of its Subject Securities (the “Rollover Shares”) free and clear of any and all Liens (other than restrictions on the right to sell or otherwise dispose of such shares imposed by state and federal securities laws) in exchange for the issuance by Parent to the Investor of a number of newly issued shares of common stock of Parent equal to the number of Rollover Shares (the “Parent Exchange Interests”, such exchange, the “Rollover”);

WHEREAS, in furtherance of the foregoing, the Investor shall, contingent upon the consummation of the Transactions in accordance with the Merger Agreement, waive any and all of such Investor’s rights under the Merger Agreement to receive cash consideration (including the Merger Consideration) in exchange for the Rollover Shares in connection with the Transactions;

WHEREAS, following the Contribution Closing (as defined herein), the Rollover Shares shall be held by Parent, be unaffected by the Merger and remain issued and outstanding equity interests in the Company;

WHEREAS, for United States federal and applicable state and local income tax purposes, it is intended that the Rollover (other than with respect to the Company Restricted Shares for which a timely and valid Section 83(b) election was not made) qualifies as a contribution described in Section 351 of the Internal Revenue Code of 1986, as amended (the “Code”, and such qualification, the “Intended Tax Treatment”); and

WHEREAS, the parties hereto desire to make certain agreements, representations, warranties and covenants in connection with the transactions contemplated by this Agreement.

NOW, THEREFORE, in consideration of the mutual covenants and conditions as hereinafter set forth, the parties hereto do hereby agree as follows:

I CONTRIBUTION

1.1. Contribution. At the Contribution Closing, upon the terms and subject to the conditions of this Agreement, (a) the Investor hereby agrees to consummate the Rollover and (b) Parent agrees to issue to the Investor the Parent Exchange Interests pursuant to the Rollover. The Investor acknowledges that (i) such Investor will not receive any cash payment for the Rollover Shares pursuant to the Transactions and (ii) Parent Exchange Interests issued in exchange for any Rollover Shares that are Company Restricted Shares as of immediately prior to the Closing will be subject to substantially the same restrictions as were applicable to the Company Restricted Shares, including with respect to the vesting schedule applicable thereto.

1.2. Contribution Closing. Subject to the satisfaction (or waiver by the parties entitled to the benefit thereof) of the conditions set forth in Section 1.3, the Rollover will take place at the time specified in Section 1.3 (the “Contribution Closing”).

1.3. Conditions to Obligations. The Contribution Closing will occur immediately prior to the Closing; provided that if the other transactions contemplated by the Merger Agreement to be consummated at Closing are not consummated within 48 hours of the Contribution Closing, the transactions contemplated by this Agreement shall be unwound and the Contribution Closing shall be null and void ab initio and of no further force or effect and be deemed to not have occurred.

1.4. Contribution Closing Deliverables. At the Contribution Closing and subject to the satisfaction of the obligations set forth in Section 1.3, the Investor shall deliver to Parent (a) duly executed stock powers, endorsed in blank, in respect of the Rollover Shares in form and substance reasonably satisfactory to Parent and (b) an Internal Revenue Service Form W-9 or Form W-8, as applicable. The Investor will, reasonably promptly after the Contribution Closing, provide Parent with information in the Investor’s possession regarding the Investor’s holding period and tax basis in the Rollover Shares.

1.5. Tax Treatment. Parent and the Investor will report the Rollover in a manner consistent with the Intended Tax Treatment, except as otherwise required by a final “determination” within the meaning of Section 1313(a) of the Code.

1.6. Termination. This Agreement shall automatically terminate if, at any time prior to the Contribution Closing, the Merger Agreement shall have been validly terminated in accordance with its terms. In the event of any termination of this Agreement as provided in this Section 1.6, this Agreement, as well as the Consent of Spouse set forth in Section 3.2, shall forthwith become wholly void and of no further force or effect (except Article IV, which shall survive such termination) and there shall be no liability on the part of any parties hereto or their respective officers or directors under this Agreement. Notwithstanding the foregoing, no party hereto shall be relieved from liability for any Willful and Material Breach of this Agreement occurring prior to the termination of this Agreement. For the avoidance of doubt, until the termination of this Agreement in accordance with this Section 1.6, the obligations of the Investor shall apply whether or not the Company Board (acting upon the Special Committee Recommendation) or the Special Committee has effected a Change of Company Recommendation.

This Agreement may only be enforced against, and any claim, action, suit or other legal proceeding based upon, arising out of, or related to this Agreement, or the negotiation, execution or performance of this Agreement, may only be brought against the entities that are expressly named as parties hereto and then only with respect to the specific obligations set forth herein with respect to such party. No former, current or future officers, employees, directors, partners, equity holders, managers, members, attorneys, agents, advisors, controlling persons or other Representatives of any party hereto (each, a “Non-Recourse Party”) shall have any liability for any obligations or liabilities of any party hereto under this Agreement or for any claim or proceeding (whether in tort, contract or otherwise) based on, in respect of or by reason of the transactions contemplated by this Agreement or in respect of any written or oral representations made or alleged to be made in connection herewith. In furtherance and not in limitation of the foregoing, each party covenants, agrees and acknowledges that no recourse under this Agreement or any other agreement referenced herein or in connection with the transactions contemplated by this Agreement shall be sought or had against any Non-Recourse Party. Notwithstanding anything to the contrary herein, no party hereto hereby waives any right to enforce its rights granted hereunder or granted under any of the other agreements or documents to be entered into among the Investor, Parent or their respective Affiliates in connection with the Transactions against any other party thereto, and any exhibits, schedules, or other attachment thereto and any documentation implementing any of the terms thereof, against any other party thereto (in each case, subject to the terms and conditions thereof).

4.13. Confidentiality. The Investor agrees that such Investor shall not, either directly or indirectly, disclose to any Person the terms of, or the negotiations and/or considerations leading to, this Agreement and the Merger Agreement, or any other information related to the Transactions (the “Confidential Information”); provided that the term “Confidential Information” shall not include information that was, is now, or becomes generally available to the public, including in any public disclosure by Parent, its Affiliates or otherwise, other than as a result of a disclosure by the Investor in violation of this Agreement. Notwithstanding anything to the contrary contained herein, nothing in this Agreement shall prohibit the Investor from disclosing the Confidential Information to (a) any of the Investor’s Representatives with a need to know the Confidential Information for the purposes of entry into this Agreement and as necessary in connection with tax filings, legal matters or other non-commercial purposes; provided that the Investor shall be responsible for its representatives maintaining the confidentiality of the Confidential Information pursuant to this Section 4.13, and (b) disclosures required by Law; provided that the Investor shall, to the extent reasonably practicable and legally permissible, give Parent prompt written notice of such requirement to enable Parent to seek a protective order or other appropriate remedy (at its sole expense) and/or waive compliance with this Agreement; provided, further, that (i) with respect to public disclosure required by applicable securities Laws or the rules or regulations of the New York Stock Exchange or any United States national securities exchange on which any of the Company Shares are then traded, the party making such disclosure shall use its reasonable best efforts to consult with the other parties hereto before making any such public disclosure and (ii) with respect to any other compelled disclosure, the Investor shall, to the extent reasonably practicable and legally permissible, give Parent prompt written notice of such requirement to enable Parent to seek a protective order or other appropriate remedy (at its sole expense) and/or waive compliance with this Agreement. If the Investor fails to obtain such protective order or other appropriate remedy to preclude the disclosure of any Confidential Information, the Investor shall only disclose that portion of the Confidential Information which the Investor is required to disclose by Law.

Exhibit A

CONSENT OF SPOUSE

I, _________________, the undersigned spouse of ______________ (the “Investor”), hereby acknowledge that I am aware that the Rollover Agreement, dated as of March 2, 2026, by and between Stallion Intermediate Corporation, a Delaware corporation, and my spouse imposes certain transfer obligations and restrictions on my spouse’s Rollover Shares (as defined in the Rollover Agreement). I agree that my spouse’s interest in the Rollover Shares is subject to the Rollover Agreement and the agreements to be entered into in connection therewith and any interest I may have in such Rollover Shares shall also be irrevocably bound by the Rollover Agreement and the agreements to be entered into in connection therewith and, further, that my community property interest in such Rollover Shares, if any, shall be similarly bound by the Rollover Agreement and the agreements to be entered into in connection therewith.

I am aware that the legal, financial and other matters contained in the Rollover Agreement and the agreements to be entered into in connection therewith are complex and I am encouraged to seek advice with respect thereto from independent legal and/or financial counsel. I have either sought such advice or determined after carefully reviewing the Rollover Agreement and the agreements to be entered into in connection therewith that I hereby waive such right.

	Acknowledged and agreed this __ day of _________ 2026
