This CHANGE IN CONTROL AGREEMENT, dated as of December 12, 2025 (this “Agreement”), is made by and between The Hain Celestial Group, Inc., a Delaware corporation (the “Company”), and Alison E. Lewis (the “Executive”). This Agreement will become effective upon the Start Date (as defined in the offer letter between the Company and the Executive, dated as of December 12, 2025 (the “Offer Letter”), and in the event the Start Date does not occur, this Agreement shall be void ab initio and of no force or effect and neither the Company nor the Executive shall have any rights or obligations hereunder.

WHEREAS, the Company considers it essential to the best interest of its stockholders to foster the continued employment of key executive management personnel; and

WHEREAS, the Board of Directors of the Company (the “Board”) recognizes that, as is the case with many publicly-held corporations, the possibility of a Change in Control (as defined below) of the Company exists from time to time and that such possibility, and the uncertainty, instability and questions which it may raise for and among key executive management personnel, may result in the premature departure or significant distraction of such management personnel to the material detriment of the Company and its stockholders; and

WHEREAS, the Board has determined that appropriate steps should be taken to reinforce, focus and encourage the continued attention and dedication of key members of the executive management of the Company and its subsidiaries, including the Executive, to their assigned duties without distraction in the face of potentially disturbing or unsettling circumstances arising from the possibility of a Change in Control of the Company.

NOW THEREFORE, in consideration of the premises and the mutual covenants herein contained, the Company and the Executive hereby agree as follows:

1. Definitions. For purposes of this Agreement, the following terms have the meanings set forth below:

1.1 “Base Salary” means the Executive’s annualized base salary as in effect from time to time.

1.2 “Cause” has the meaning as set forth in the Offer Letter.

1.3 “Change in Control” means the occurrence of any of the following:

With respect to any payment that is “nonqualified deferred compensation” as defined under Section 409A, it is the intent of the Company that the definition of “Change in Control” satisfies, and be interpreted in a manner that satisfies, the applicable requirements of Section 409A of the Internal Revenue Code of 1986, as amended (“Section 409A”). If the definition of “Change in

Control” would otherwise frustrate or conflict with the intent expressed above, that definition to the extent possible shall be interpreted and deemed amended so as to avoid such conflict.

1.4 “Company” means The Hain Celestial Group, Inc. and any successor to its business and/or assets which assumes (either expressly, by operation of law or otherwise) and/or agrees to perform this Agreement by operation of law or otherwise (except in determining, under Section 1.3 hereof, whether or not any Change in Control of the Company has occurred in connection with such succession).

1.5 “Good Reason” has the meaning as set forth in the Offer Letter.

1.6 “Person” shall have the meaning ascribed thereto in Section 3(a)(9) of the Exchange Act, as modified, applied and used in Sections 13(d) and 14(d) thereof; provided, however, a Person shall not include (i) the Company or any of its subsidiaries, (ii) a trustee or other fiduciary holding securities under an employee benefit plan of the Company or any of its subsidiaries (in its capacity as such), (iii) an underwriter temporarily holding securities pursuant to an offering of such securities, or (iv) a corporation or other entity owned, directly or indirectly, by the stockholders of the Company in substantially the same character and proportions as their ownership of voting securities of the Company.

1.7 “Target Award” means the target amount of the Executive’s annual incentive award under annual incentive plans to be adopted by the Compensation Committee of the Board.

2. Change in Control Severance.

2.1 Severance. If a Change in Control occurs during the Term and, during the period commencing on the date of the Change in Control and ending twelve (12) months following the date of the Change in Control, the Executive’s employment with the Company is terminated by the Company without Cause or by the Executive for Good Reason, the Executive shall receive cash severance (the “Change in Control Severance”) in an amount equal to two (2) times the sum of the Executive’s Base Salary plus the Executive’s Target Award, which shall be paid in equal installments over a two (2)-year period in accordance with the Company’s regular payroll schedule, with the first payment being made on the sixtieth (60) day after the termination of the Executive’s employment.

2.2 Release; Section 409A; No Offset or Duty to Mitigate. The Change in Control Severance shall in all respects be conditioned on (i) the Executive executing within twenty-one (21) days of termination (or forty-five (45) days to the extent required by applicable law) and not revoking a written release in a form provided by the Company releasing the Company from any and all claims with respect to all matters arising out of or related to the Executive’s employment by the Company or the termination of the Executive’s employment (the “Release”), which Release will not release the Executive’s right to severance or to indemnification against third party claims, or the Executive’s rights as a shareholder of the Company, and will not increase the scope or duration of any post-employment restrictions on the Executive’s activities, (ii) the Executive’s compliance with the terms of the Release, including any return of property, non-disparagement, and confidentiality provisions, and (iii) the Executive’s continued compliance with the Executive’s obligations under any continuing provisions in the Executive’s employment

agreement or offer letter with the Company or any other agreement between the parties, in each case relating to confidentiality, assignment of inventions, non-competition, non-solicitation / non-interference, or non-disparagement. In no event shall the timing of the Executive’s execution of the Release, directly or indirectly, result in the Executive designating the calendar year of payment of the Change in Control Severance, and if a payment that is “nonqualified deferred compensation” as defined under Section 409A is subject to execution of the Release and could be made in more than one taxable year, payment shall be made in the later taxable year. If the Executive is considered a “specified employee” (as defined under Section 409A) and payment of any amounts under this Agreement is required to be delayed for a period of six (6) months after separation from service pursuant to Section 409A, payment of such amounts shall be delayed as required by Section 409A, and the accumulated postponed amounts shall be paid in a lump-sum payment within five (5) days after the end of the six (6) month period. If the Executive dies during the postponement period prior to the payment of benefits, the amounts postponed on account of Section 409A shall be paid to the personal representative of the Executive’s estate within sixty (60) days after the date of the Executive’s death. The Executive’s rights to the Change in Control Severance under this Agreement will not be subject to offset by compensation from other sources or a duty on the Executive’s part to mitigate or seek other employment.

2.3 Other Agreements, Policies or Arrangements. In the event the Executive becomes entitled to receive the Change in Control Severance, the payment to the Executive of such Change in Control Severance shall be in lieu of, and not in addition to, any severance payable to the Executive under the terms of any other employment agreement, offer letter, or other agreement with the Company, or any Company severance plan, policy, program, or arrangement. Except as provided in the preceding sentence, this Agreement is not intended to and shall not modify or supersede any such employment agreement, offer letter, or other agreement or arrangement between the Executive and the Company in effect from time to time. This Agreement is not intended to and shall not modify or supersede the provisions of any equity award agreement between the Company and the Executive; the treatment of the Executive’s equity awards upon a Change in Control shall be governed by the applicable equity award agreements.

3. Term of this Agreement. This Agreement shall commence on the date hereof and shall continue in effect initially for a period of three (3) years (the “Initial Term”). The term of this Agreement shall automatically be extended for additional one (1) year periods (each, a “Renewal Term,” and together with the Initial Term, the “Term”) if the Executive has remained continuously employed through the last day of the Initial Term or Renewal Term, unless the Company provides written notice to the Executive at least six (6) months prior to the end of the Initial Term or Renewal Term of the Company’s intent not to extend the Term. Additionally, if a Change in Control occurs during the Term while the Executive remains employed with the Company, then this Agreement shall continue in effect for a period of twelve (12) months following the date of the Change in Control, to determine whether an event occurs during such twelve (12) month period that entitles the Executive to the Change in Control Severance.

4. Successors; Binding Agreement.

4.1 Successors. In addition to any obligations imposed by law upon any successor to the Company, the Company will require any successor (whether direct or indirect, by purchase,

merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company to expressly assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place.

4.2 Binding Agreement. This Agreement shall inure to the benefit of and be enforceable by the Executive’s personal or legal representatives, executors, administrators, successors, and heirs. If the Executive shall die while any amount would still be payable to the Executive hereunder if the Executive had continued to live, all such amounts, unless otherwise provided herein, shall be paid in accordance with the terms of this Agreement to the executors, personal representatives or administrators of the Executive’s estate.

5. Notices. For the purpose of this Agreement, notices and all other communications provided for in this Agreement shall be in writing and shall be deemed to have been duly given when delivered or mailed by United States certified mail, return receipt requested, postage prepaid, or via a nationally recognized overnight courier, addressed to the respective addresses set forth below, or to such other address as either party may have furnished to the other in writing in accordance herewith, except that notice of change of address shall be effective only upon actual receipt:

6. Arbitration. Section 15 of the Offer Letter shall govern this Agreement with respect to arbitration of any disputes arising out of or related to this Agreement.

7. Section 409A. This Agreement is intended to comply with or otherwise be exempt from Section 409A and its corresponding regulations, to the extent applicable, and shall be so construed. Notwithstanding anything in this Agreement to the contrary, payments of “nonqualified deferred compensation” subject to Section 409A may only be made under this Agreement upon an event and in a manner permitted by Section 409A, to the extent applicable. For purposes of Section 409A, all payments of “nonqualified deferred compensation” subject to Section 409A to be made upon the termination of the Executive’s employment under this Agreement may only be made upon a “separation from service” under Section 409A. Each payment made under this Agreement, including each installment of Change in Control Severance, shall be treated as a separate payment and the right to a series of installment payments under this Agreement is to be treated as a right to a series of separate payments. In no

event shall the Executive, directly or indirectly, designate the calendar year of payment with respect to any amount that is “nonqualified deferred compensation” subject to Section 409A. Nothing herein shall be construed as having modified the time and form of payment of any amounts or payments of “nonqualified deferred compensation” within the meaning of Section 409A that were otherwise payable pursuant to the terms of any agreement between the Company and the Executive in effect prior to the date of this Agreement.

8. Section 280G. Notwithstanding any other provision of this Agreement or any other plan, arrangement or agreement to the contrary, if any of the payments provided or to be provided by the Company to the Executive pursuant to the terms of this Agreement or otherwise (the “Covered Payments”) constitute parachute payments within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended, and, but for this Section 8, would be subject to the excise tax imposed under Section 4999 of the Internal Revenue Code of 1986, as amended (or any successor provision thereto), or any similar tax imposed by state or local law or any interest or penalties with respect to such taxes (collectively, the “Excise Tax”), then prior to making the Covered Payments, a calculation shall be made comparing (i) the Net Benefit (as defined below) to the Executive of the Covered Payments after payment of the Excise Tax to (ii) the Net Benefit to the Executive if the Covered Payments are limited to the extent necessary to avoid being subject to the Excise Tax. Only if the amount calculated under (i) above is less than the amount under (ii) above will the Covered Payments be reduced to the minimum extent necessary to ensure that no portion of the Covered Payments is subject to the Excise Tax (that amount, the “Reduced Amount”). “Net Benefit” shall mean the present value of the Covered Payments net of all federal, state, local, foreign income, employment and excise taxes.

a. Any such reduction shall be made in accordance with Section 409A and the following:

(i) the Covered Payments consisting of cash severance benefits that do not constitute nonqualified deferred compensation subject to Section 409A shall be reduced first, in reverse chronological order;

(ii) all other Covered Payments consisting of cash payments, and Covered Payments consisting of accelerated vesting of equity based awards to which Treas. Reg. § 1.280G-1 Q/A-24(c) does not apply, and that in either case do not constitute nonqualified deferred compensation subject to Section 409A, shall be reduced second, in reverse chronological order;

(iii) all Covered Payments consisting of cash payments that constitute nonqualified deferred compensation subject to Section 409A shall be reduced third, in reverse chronological order; and

(iv) all Covered Payments consisting of accelerated vesting of equity-based awards to which Treas. Reg. § 1.280G-1 Q/A-24(c) applies shall be the last Covered Payments to be reduced.

b. Any determination required under this Section 8 shall be made in writing in good faith by an independent accounting firm selected by the Company (the “Accountants”). The

Company and the Executive shall provide the Accountants with such information and documents as the Accountants may reasonably request in order to make a determination under this Section 8. For purposes of making the calculations and determinations required by this Section 8, the Accountants may rely on reasonable, good-faith assumptions and approximations concerning the application of Section 280G and Section 4999 of the Internal Revenue Code of 1986, as amended. The Accountants’ determinations shall be final and binding on the Company and the Executive. The Company shall be responsible for all fees and expenses incurred by the Accountants in connection with the calculations required by this Section 8.

c. It is possible that after the determinations and selections made pursuant to this Section 8 the Executive will receive Covered Payments that are in the aggregate more than the amount intended or required to be provided after application of this Section 8 (“Overpayment”) or less than the amount intended or required to be provided after application of this Section 8 (“Underpayment”).

(i) In the event that: (A) the Accountants determine, based upon the assertion of a deficiency by the Internal Revenue Service against either the Company or the Executive that the Accountants believe has a high probability of success, that an Overpayment has been made or (B) it is established pursuant to a final determination of a court or an Internal Revenue Service proceeding that has been finally and conclusively resolved that an Overpayment has been made, then the Executive shall pay any such Overpayment to the Company together with interest at the applicable federal rate (as defined in Section 7872(f)(2)(A) of the Internal Revenue Code of 1986, as amended) from the date of the Executive’s receipt of the Overpayment until the date of repayment.

(ii) In the event that: (A) the Accountants, based upon controlling precedent or substantial authority, determine that an Underpayment has occurred or (B) a court of competent jurisdiction determines that an Underpayment has occurred, any such Underpayment will be paid promptly by the Company to or for the benefit of the Executive together with interest at the applicable federal rate (as defined in Section 7872(f)(2)(A) of the Internal Revenue Code of 1986, as amended) from the date the amount should have otherwise been paid to the Executive until the payment date.

9. Miscellaneous. No provision of this Agreement may be modified, waived or discharged unless such waiver, modification or discharge is agreed to in writing, approved by the Compensation Committee of the Board, and signed by the Executive and an authorized officer of the Company. No waiver by either party hereto at any time of any breach by the other party hereto of, or compliance with, any condition or provision of this Agreement to be performed by such other party shall be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or subsequent time. No agreements or representations, oral or otherwise, express or implied, with respect to the subject matter hereof have been made by either party which are not expressly set forth in this Agreement, and this Agreement supersedes any prior agreements between the Company and the Executive relating to the subject matter hereof. Any payments provided for hereunder shall be paid net of any applicable withholding required under federal, state or local law and any additional withholding to which the Executive has agreed. The rights and obligations of the Company and the Executive under this Agreement shall survive the expiration of the Term.

10. Validity. The invalidity or unenforceability of any provision of this Agreement shall not affect the validity or enforceability of any other provision of this Agreement, which shall remain in full force and effect.

11. Counterparts. This Agreement may be executed in several counterparts, each of which shall be deemed to be an original but all of which together will constitute one and the same instrument.

12. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New Jersey without regard to the conflicts of law provisions thereof.

IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of the date and year first written above.
