The Timken Company 1996 Deferred Compensation Plan for officers and other key employees, amended and restated effective as of August 2, 2022

The Timken Company (the “Company”) hereby amends and restates, effective August 2, 2022, its 1996 Deferred Compensation Plan (the “Plan”), which was originally established on November 3, 1995, amended and restated effective as of April 20, 1999, further amended by Amendments No. 1 and No. 2, and amended and restated effective as of December 31, 2008, December 31, 2010 and June 30, 2014.

Effective as of June 30, 2014 (the “Split Date”), certain assets and liabilities attributable to the benefits accrued for the Transferred Participants were spun off (the “Spin-Off”) to form a new plan to be known as the TimkenSteel Corporation 2014 Deferred Compensation Plan (the “TimkenSteel Plan”) which is sponsored by TimkenSteel Corporation. On and after the Split Date, such Transferred Participants ceased to be Participants under the Plan and became participants under the TimkenSteel Plan, and the terms of the TimkenSteel Plan shall govern the benefits accrued by the Transferred Participants under this Plan prior to the Split Date.

The Company previously amended and restated the Plan effective January 1, 2015 and January 1, 2019, and now desires to amend the Plan to make certain changes to the Plan deemed desirable in the administration of the Plan, and to restate the Plan as so amended effective August 2, 2022.

Notwithstanding Section 1 of this Article IV, no amendment or termination of the Plan shall adversely affect any Participant or Beneficiary who has an Account, or result in the acceleration of payment of the amount of any Account (except as otherwise permitted under the Plan), without the consent of the Participant or Beneficiary; provided, however, that the consent requirement of Participants or Beneficiaries to certain actions shall not apply to any amendment or termination made by the Company pursuant to Section 9(iii) of Article V. Notwithstanding the preceding sentence, the Committee, in its sole discretion, may terminate the Plan to the extent and in circumstances described in Treasury Regulation Section 1.409A-3(j)(4)(ix), or any successor provision.

1. Non-alienation of Deferred Compensation. Except as permitted by the Plan and subject to Section 9(ii) of this Article V, no right or interest under the Plan of any Participant or Beneficiary shall, without the written consent of the Company, be (i) assignable or transferable in any manner, (ii) subject to alienation, anticipation, sale, pledge, encumbrance, attachment, garnishment or other legal process or (iii) in any manner liable for or subject to the debts or liabilities of the Participant or Beneficiary.

2. Participation by Associates of Subsidiaries. An Eligible Associate who is employed by a Subsidiary and elects to participate in the Plan shall participate on the same basis as an associate of the Company. The Account or Accounts of a Participant employed by a Subsidiary shall be paid in accordance with the Plan solely by such Subsidiary to the extent

attributable to Base Salary or Incentive Compensation that would have been paid by such Subsidiary in the absence of deferral pursuant to the Plan.

3. Interest of Associate. The obligation of the Company under the Plan to make payment of amounts reflected in an Account merely constitutes the unsecured promise of the Company to make payments from its general assets or in the form of its Common Shares, or to cause TimkenSteel Corporation to make payments in the form of TimkenSteel Shares, as the case may be, as provided herein, and no Participant or Beneficiary shall have any interest in, or a lien or prior claim upon, any property of the Company. The obligation of TimkenSteel Corporation under the Plan to make payment of amounts reflected in a TimkenSteel Shares Subaccount merely constitutes the unsecured promise of TimkenSteel Corporation to make payments in the form of its TimkenSteel Shares, as provided herein, and no Participant or Beneficiary shall have any interest in, or a lien or prior claim upon, any property of TimkenSteel Corporation. Further, no Participant or Beneficiary shall have any claim whatsoever against any Subsidiary for amounts reflected in an Account. Nothing in the Plan shall be construed as guaranteeing future employment to Eligible Associates and nothing in the Plan shall be considered in any manner a contract of employment. It is the intention of the Company that the Plan be unfunded for tax purposes of Title I of ERISA. The Company may create a trust to hold funds, Common Shares or other securities to be used in payment of its obligations under the Plan, and may fund such trust; provided, however, that any funds contained therein shall remain liable for the claims of the Company’s general creditors and provided, further, that no amount shall be transferred to trust if, pursuant to Section 409A of the Code, such amount would, for purposes of Section 83 of the Code, be treated as property transferred in connection with the performance of services.

4. Claims of Other Persons. The provisions of the Plan shall in no event be construed as giving any other person, firm or corporation any legal or equitable right as against the Company or any Subsidiary or the officers, employees or directors of the Company or any Subsidiary, except any such rights as are specifically provided for in the Plan or are hereafter created in accordance with the terms and provisions of the Plan.

5. Special Rules for Participants Prior to January 1, 2018. Notwithstanding any provision of this Plan to the contrary, the following provisions of this Section 5 shall apply to any Eligible Associate who was an Eligible Associate prior to January 1, 2018 and has less than three Years of Service as of the date an Excess Core Contribution is to be made:

(i)     If such Eligible Associate has less than three Years of Service as of the date of an Excess Core Contribution, he or she shall, pursuant to Article II, elect (or in the absence of a properly filed Election Agreement, shall be deemed to have elected) to defer all of his or her Excess Core Contribution for the Year (and any Election Agreement to the contrary shall be disregarded and treated as not properly filed hereunder). If such Eligible Associate fails to file properly a Payment Election for such Excess Core Contributions, the Eligible Associate shall be deemed to have timely filed an Election Agreement with a Payment Election electing a lump sum payment to be made within 2-1/2 months after the close of the Year during which the Eligible Associate achieved three Years of Service, or if earlier, the close of the Year during which the Eligible Associate incurs a Termination of Employment due to death, Disability (as defined in the Savings and Investment Pension Plan) or Retirement (as defined in the Savings and Investment Pension Plan).

(ii) Such Eligible Associate may not elect a date for commencement of his or her Excess Core Contributions pursuant to Section 3(ii)(1)(B) of Article II that is prior to the date such Eligible Associate will have achieved three Years of Service.

(iii)      If, as of the date of such Eligible Associate’s Termination of Employment, the Eligible Associate has not achieved three Years of Service, the Eligible Associate shall forfeit his or her Excess Core Contributions Subaccount, including any interest credited to such Subaccount. Notwithstanding the preceding sentence, such Eligible Associate shall not forfeit his or her Excess Core Contributions Subaccount if the Eligible Associate’s Termination of Employment is due to death, Disability (as defined in the Savings and Investment Retirement Plan) or Retirement (as defined in the Savings and Investment Retirement Plan). Further, such Eligible Associate’s Excess Core Contribution Subaccount will not be immediately paid upon a Change in Control pursuant to Section 7(i) of Article II

if, at the time of such Change in Control, the Eligible Associate has less than three Years of Service.

6. Severability. The invalidity and unenforceability of any particular provision of the Plan shall not affect any other provision hereof, and the Plan shall be construed in all respects as if such invalid or unenforceable provision were omitted herefrom.

7. Governing Law. Except to the extent preempted by federal law, the provisions of the Plan shall be governed and construed in accordance with the laws of the State of Ohio.

(i)     The Plan is intended to serve the purposes of and to be consistent with the Long-Term Incentive Plans and any similar plan approved by the Committee for purposes of the Plan. The issuance or transfer of Common Shares pursuant to the Plan shall be subject in all respects to the terms and conditions of the Long-Term Incentive Plans and any other such plan. Without limiting the generality of the foregoing, Common Shares credited to the Account(s) of Participants pursuant to the Plan as Incentive Compensation shall be taken into account for purposes of Section 3 of the Long-Term Incentive Plans (Maximum Shares Available Under the Plan) and for purposes of the corresponding provisions of any other such plan.

(ii)     The issuance or transfer of TimkenSteel Shares pursuant to the Plan shall be made by TimkenSteel Corporation and shall be subject in all respects to the terms and conditions of the TimkenSteel Corporation Long-Term Incentive Plan and any other such plan. Without limiting the generality of the foregoing, TimkenSteel Shares credited to the TimkenSteel Shares Subaccount of Participants pursuant to the Plan as Incentive Compensation shall be taken into account for purposes of Section 3 of the TimkenSteel Corporation Long-Term Incentive Plan (Maximum Shares Available Under the Plan) and for purposes of the corresponding provisions of any other such plan

(i)     To the extent applicable, it is intended that the Plan (including all amendments thereto) comply with the provisions of Section 409A of the Code, so that the income inclusion provisions of Section 409A(a)(1) of the Code do not apply to the Participant or a

Beneficiary. The Plan shall be administered in a manner consistent with this intent. In furtherance of, but without limiting the generality of the foregoing, amounts in the Pre-2005 Subaccounts, which are intended to qualify for “grandfathered” status pursuant to Treasury Regulation Section 1.409A-6(a), shall not be subject to the provisions of Section 409A of the Code and shall be governed by the terms and conditions specified in the Plan as in effect prior to January 1, 2005.

(ii)     Neither a Participant nor any of a Participant’s creditors or beneficiaries shall have the right to subject any deferred compensation (within the meaning of Section 409A of the Code) payable under the Plan to any anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, attachment or garnishment, provided that to the extent permitted by Section 409A of the Code, payment of part or all of a Participant’s interest under the Plan may be made to an individual other than the Participant to the extent necessary to fulfill a domestic relations order as defined in Section 414(p)(1)(B) of the Code. Except as permitted under Section 409A of the Code, any deferred compensation (within the meaning of Section 409A of the Code) payable to a Participant or for a Participant’s benefit under the Plan may not be reduced by, or offset against, any amount owing by a Participant to the Company or any of its affiliates.

(i)    Headings in the Plan are inserted for convenience of reference only and are not to be considered in the construction of the provisions hereof.

(ii)     Any reference in the Plan to Section 409A of the Code will also include any applicable proposed, temporary, or final regulations or any other applicable formal guidance promulgated with respect to such Section 409A of the Code by the U.S. Department of Treasury or the Internal Revenue Service. Further, any specific reference to a Code section or a Treasury Regulation section shall include any successor provision of the Code or the Treasury Regulation, as applicable.

IN WITNESS WHEREOF, the Company has caused this Plan to be executed by two duly authorized officers at North Canton, Ohio, this 8th day of September, 2022.
