2024 Parker-Hannifin Corporation Stock Appreciation Rights Terms and Conditions

Pursuant to the Stock Appreciation Rights Award Agreement (the “Award Agreement”) available on the website of the third party Plan administrator for Parker-Hannifin Corporation (the “Company”), the Human Resources and Compensation Committee (the “Committee”) of the Board of Directors (the “Board”) of the Company has awarded you a number of Stock Appreciation Rights (“SARs”). The SARs have been awarded to you as of the grant date specified in the Award Agreement (the “Grant Date”), and the SARs are subject to the terms, conditions, and restrictions set forth in the Parker-Hannifin Corporation 2023 Omnibus Stock Incentive Plan, as amended from time to time (the “Plan”) and these Stock Appreciation Rights Terms and Conditions (SAR-OS33) (the “Terms and Conditions”). To the extent that, in accordance with the terms of the Plan, the Committee has delegated to any persons any of the Committee’s authority with respect to these Terms and Conditions, references to the Committee in these Terms and Conditions shall be deemed to be references to those persons with respect to authority so delegated.

1.Description of SARs. Your SARs award entitles you to receive the increase in value between the Grant Price set forth in your Award Agreement and the Fair Market Value at exercise (the “Appreciation”) of the number of Common Shares to which your award applies, subject to these Terms and Conditions. Upon exercise, the Appreciation will be paid to you in Common Shares having a value equal to the amount of the Appreciation. The calculation of Appreciation is described in more detail below. Your unexercised SARs will expire and cease to be exercisable without further action or notice on the Expiration Date set forth in your Award Agreement or such earlier date (a “Lapse Date”) as may be applicable pursuant to Section 3(d) of these Terms and Conditions. Solely for purposes of this Agreement, “Fair Market Value” means the price of a Common Share at the time of exercise as reasonably determined by the Company in compliance with Section 409A of the Code (to the extent applicable), unless otherwise determined by the Committee.

2.Calculation of Appreciation. Appreciation shall be determined by the Company (or its third party Plan administrator) by subtracting the Grant Price from the Fair Market Value of a Common Share at the time of your exercise of SARs, and multiplying the result by the number of SARs exercised. The number of Common Shares issued upon exercise of SARs will be the number derived from dividing the Appreciation by the Fair Market Value at exercise of a Common Share, rounded down to the nearest whole share. You will not receive cash for any fractional share eliminated by rounding.

3.Vesting and Exercisability of SARs.

(a)Subject to these Terms and Conditions, all or a portion of the SARs will vest and become exercisable on the vesting date(s) described in the Award Agreement (each a “Vesting Date”), provided that you have remained in the continuous full-time employment of the Company and its Subsidiaries (collectively referred to herein as the “Parker Companies”) through the applicable Vesting Date(s).

(b)Notwithstanding anything to the contrary in these Terms and Conditions, if your continuous full-time employment with the Parker Companies is terminated prior to the applicable Vesting Date, your awards shall be treated as follows:

For purposes of these Terms and Conditions “Retirement” shall have the meaning set out in the applicable retirement plan or policy of the Parker Companies in which you participate or, if Retirement is not defined in an applicable retirement plan or policy, Retirement shall mean your termination of employment with the Parker Companies after the attainment of age 55 and ten years of service.

(c)Except as otherwise provided in Section 3(d), any SARs that have vested and become exercisable in accordance with this Section 3 may be exercised only while you are a full-time employee of the Parker Companies at any time until the earlier of the Expiration Date or the applicable Lapse Date.

(d)If your continuous full-time employment with the Parker Companies is terminated prior to the Expiration Date for any reason, any vested and exercisable SARs shall remain exercisable until the Lapse Date set forth below:

(e)For purposes of this Section 3, your continuous full-time employment with the Parker Companies shall not be deemed to have been interrupted, and you shall not be deemed to have

ceased to be an employee of the Parker Companies, by reason of (1) the transfer of your employment among the Parker Companies, or (2) the transfer of your employment to an entity that is 50% owned (directly or indirectly) by the Company provided that you remain actively and continuously employed by such entity.

4.Forfeiture of SARs. Any SARs that have not yet vested and become exercisable pursuant to Section 3 shall be forfeited automatically without further action or notice if you cease to be employed by the Parker Companies prior to a Vesting Date other than as provided in Section 3(b).

5.Exercise and Settlement Procedures.

(a)Exercise of all or any portion of your vested and exercisable SARs shall be subject to such exercise procedures of the Company and its third party Plan administrator, as the same shall be in effect from time to time. Upon your exercise of SARs in accordance with such procedures and these Terms and Conditions, the Company will instruct its stock transfer agent to issue the net number of Common Shares you are entitled to receive.

(b)Any vested and exercisable SARs granted under your Award Agreement that have not lapsed and have net Appreciation (after all applicable withholding taxes) but that remain unexercised on the business day preceding the Expiration Date shall automatically be self-exercised on the Expiration Date. NOTE: AWARDS THAT LAPSE PRIOR TO THE ORIGINAL EXPIRATION DATE AND AWARDS THAT HAVE NOT BEEN ACCEPTED BY THE PARTICIPANT ARE NOT ELIGIBLE FOR SELF-EXERCISE. ANY AWARDS THAT HAVE NOT BEEN EXERCISED ON OR BEFORE THE EXPIRATION DATE SHALL EXPIRE WITH NO VALUE.

(c)The Company’s obligations with respect to the SARs shall be satisfied in full upon the delivery of the Common Shares underlying vested SARs that are exercised in accordance with these Terms and Conditions.

6.Transferability. Neither the SARs nor any interest therein or in the Common Shares underlying the SARs may be transferred, assigned, pledged or hypothecated in any manner, or be subject to execution, attachment or similar process, by operation of law or otherwise, except by will or the laws of descent and distribution or pursuant to a beneficiary designation made in accordance with Section 11, unless otherwise provided herein or under the Plan. Your SARs are not transferable or assignable during your life except to (a) your spouse, children or their lineal descendants (“Immediate Family Members”); (b) one or more trusts for the benefit of you and/or one or more of your Immediate Family Members; or (c) a partnership or limited liability company in which you or your Immediate Family Members are the only partners or members; provided, however, in each case that you (i) submit a completed SAR Assignment Form to the Plan Administrator or comply with other procedures in effect at the time of the transfer and (ii) do not receive any consideration for the transfer. All transferred SARs remain subject to the terms, conditions and restrictions of the Plan and these Terms and Conditions (except that such transferred SARs are not transferable by the transferee during life). Any purported transfer or encumbrance in violation of the provisions of this Section 6 shall be null and void, and the other party to any such purported transaction shall not obtain any rights to or interest in such SARs.

7.No Rights to Future Awards. By voluntarily acknowledging and accepting your award of SARs, you acknowledge and understand that the SARs shall not form part of any contract of employment between you and the Company. Nothing in these Terms and Conditions, your Award

Agreement, the Plan or the plan summary and prospectus which describes the Plan (the “Prospectus”) shall confer upon you any right to continue to receive stock incentive awards in the future. You further acknowledge that your award of SARs is for future services and is not under any circumstances to be considered compensation for past services.

8.Detrimental Activity; Clawback Policies.

(a)If the Committee finds in its discretion that you have engaged in any Detrimental Activity (as defined in the Plan), the Committee may at any time and in its sole discretion cancel and revoke all or any unexercised portion of your SARs. In addition, if the Committee finds that you have engaged in any Detrimental Activity, either during your employment with the Company or within twelve months thereafter, then you shall be required to (a) return to the Company, in exchange for payment by the Company of any amount actually paid therefor by you, all Common Shares that you have not disposed of that were issued pursuant to these Terms and Conditions within twelve months prior to the commencement of such Detrimental Activity, and (b) pay to the Company in cash, within ten days after demand therefor, the difference between any amount actually paid therefor by you and the Fair Market Value at exercise of all Common Shares that you have disposed of that were issued pursuant to these Terms and Conditions. The Plan defines “Detrimental Activity” as any conduct or activity, whether or not related to the business of the Company or a Subsidiary, that is determined in individual cases, by the Committee or its express delegate, to be detrimental to the interests of the Company or a Subsidiary, including without limitation (i) the rendering of services to an organization, or engaging in a business, that is, in the judgment of the Committee or its express delegate, in competition with the Company; (ii) the disclosure to anyone outside of the Company, or the use for any purpose other than the Company’s business, of confidential information or material related to the Company, whether acquired by the Participant during or after employment with the Company; (iii) fraud, embezzlement, theft-in-office or other illegal activity; or (iv) a violation of the Company’s Code of Ethics or other policies.

(b)By accepting your award of SARs, you acknowledge that the SARs and the Common Shares underlying such SARs shall be subject to the terms and conditions of the Claw-back Policy of Parker-Hannifin Corporation that applies to compensation granted or paid on or after July 1, 2009 (as may be amended and restated from time to time) and the Parker-Hannifin Corporation Section 16 Officer Clawback Policy (as may be amended and restated from time to time), to the extent provided under the terms of each such policy.

9.Relation to Other Benefits. Any economic or other benefit to you under these Terms and Conditions or the Plan shall not be taken into account in determining any benefits to which you may be entitled under any profit-sharing, retirement or other benefit or compensation plan maintained by the Parker Companies and shall not affect the amount of any life insurance coverage available to any beneficiary under any life insurance plan covering employees of the Parker Companies. Without limiting the foregoing, by voluntarily acknowledging and accepting your award of SARs, you agree that no benefits accruing under your Award Agreement, these Terms and Conditions or the Plan will be reflected in any severance or indemnity payments that the Parker Companies may make or be required to make to you in the future, regardless of the jurisdiction in which you may be located.

10.Taxes and Withholding. The Parker Companies have the right to deduct or cause to be deducted, or collect or cause to be collected, with respect to the taxation of the SARs, any federal, state or local taxes, social taxes or other taxes required to be withheld or paid with respect to the SARs, and you will be required to pay any such amounts or such amounts will be deducted from any amount payable to you. To the extent the Parker Companies are required to withhold any federal, state, local, foreign or

other taxes in connection with the delivery of Common Shares under these Terms and Conditions, then the Company or Subsidiary (as applicable) will retain a number of Common Shares otherwise deliverable hereunder with a value equal to the required withholding (based on the fair market value of the Common Shares on the date of delivery); provided that in no event shall the value of the Common Shares retained exceed the minimum amount of taxes required to be withheld or such other amount that will not result in a negative accounting impact.

11.Beneficiary Designation. To the extent permitted by the Committee, in its sole discretion, you shall have the right to designate one or more beneficiaries to receive all or part of any Common Shares underlying the SARs in the event of your death. Any beneficiary designation permitted by the Committee shall be effective when it is submitted in writing to the Committee during your lifetime on a form prescribed by the Committee. The submission of a new beneficiary designation shall cancel all prior beneficiary designations. Any finalized divorce or marriage subsequent to the date of a beneficiary designation shall revoke such designation, unless in the case of divorce your previous spouse was not designated as beneficiary and unless in the case of marriage your new spouse was previously designated as beneficiary. If you are married, your spouse shall consent to any designation of a beneficiary other than the spouse, and the spouse’s consent shall be witnessed by a notary public. If you fail to designate a beneficiary as may be permitted by the Committee, or if such beneficiary designation is revoked by marriage, divorce, or otherwise without execution of a new designation, or if every person designated as beneficiary predeceases you or dies prior to the exercise of your SARs, then the Company shall issue any Common Shares payable under your SARs to the estate of the last to die of you and any beneficiaries.

12.Adjustments. The SARs and the number of Common Shares deliverable pursuant to exercise of the SARs, and the other terms and conditions of the grant evidenced by these Terms and Conditions, are subject to adjustment, including as provided in Sections 4.3 and 12 of the Plan.

13.Compliance with Law. The Company shall make reasonable efforts to comply with all applicable federal and state securities laws and listing requirements with respect to the SARs; provided, however, notwithstanding any other provision of these Terms and Conditions, and only to the extent permitted under Section 409A of the Code, the Company shall not be obligated to deliver any Common Shares pursuant to these Terms and Conditions if the delivery thereof would result in a violation of any such law or listing requirement. The Company intends that the Award Agreement and these Terms and Conditions be exempt from the requirements of Section 409A of the Code and they will be interpreted, construed and administered accordingly.

14.Amendments. Subject to the terms of the Plan, the Committee may amend these Terms and Conditions upon written notice to you. Any amendment to the Plan shall be deemed to be an amendment to these Terms and Conditions to the extent that the amendment is applicable hereto. Notwithstanding the foregoing, no amendment of the Plan or these Terms and Conditions shall adversely affect your rights under these Terms and Conditions without your consent unless the Committee determines that such amendment is necessary or advisable to conform the Plan or these Terms and Conditions to any present or future law, regulation or rule applicable to the Plan.

15.Severability. In the event that one or more of the provisions of these Terms and Conditions shall be invalidated for any reason by a court of competent jurisdiction, any provision so invalidated shall be deemed to be separable from the other provisions hereof, and the remaining provisions hereof shall continue to be valid and fully enforceable.

16.Relation to Plan. These Terms and Conditions and all rights under your Award Agreement and these Terms and Conditions are at all times subject to all other terms, conditions and provisions of the Plan (and any rules or procedures adopted under the Plan by the Committee). All capitalized terms not defined in these Terms and Conditions shall have the meaning ascribed to such terms in the Plan. In the event of a conflict between the terms of the Plan and these Terms and Conditions, your Award Agreement or the Prospectus, the terms of the Plan shall control. These Terms and Conditions, the Plan and the Award Agreement contain the entire agreement and understanding of the parties with respect to the subject matter contained in these Terms and Conditions, and supersede all prior written or oral communications, representations and negotiations in respect thereto.

17.Successors and Assigns. Without limiting Section 6, the provisions of these Terms and Conditions shall inure to the benefit of, and be binding upon, your successors, administrators, heirs, legal representatives and assigns, and the successors and assigns of the Company.

18.Governing Law. The interpretation, performance, and enforcement of these Terms and Conditions shall be governed by the laws of the State of Ohio, without regard to its conflict of law rules. Any dispute, disagreement or question which arises under or as a result of, or in any way relates to, the interpretation, construction or application of the terms of the Plan, the Award Agreement or these Terms and Conditions will be determined and resolved by the Committee. Such determination and resolution by the Committee will be final, binding and conclusive for all purposes.

19.Non-U.S. Employees. Notwithstanding any provision of these Terms and Conditions, if your employment with the Parker Companies is subject to the rules and regulations of one or more non-United States jurisdictions, then your SARs shall be subject to any special terms and conditions as set forth in any appendix for your country (an “Appendix”). Moreover, if you relocate to one of the countries included in an Appendix, the special terms and conditions for such country will apply to you, to the extent the Company determines that the application of such terms and conditions is necessary or advisable in order to comply with local law or facilitate the administration of these Terms and Conditions or the Plan. An Appendix shall constitute part of these Terms and Conditions.
