2014 DEFERRED COMPENSATION PLAN 

(EFFECTIVE JUNE 30, 2014) 

TimkenSteel Corporation (the “Company”) hereby adopts the 2014 Deferred Compensation Plan (the “Plan”), effective
June 30, 2014, as set forth herein. The Plan provides key executives with the opportunity to defer base salary, incentive compensation payments payable in cash or Common Shares, and certain Company contributions, in accordance with the
provisions set forth below. The Plan was formed as a result of a spin-off (the “Spin-Off”), effective June 30, 2014 (the “Spin-Off Date”) of certain assets and liabilities from The Timken Company 1996 Deferred Compensation
Plan (As Amended and Restated Effective December 31, 2010) (the “Timken Plan”) relating to the benefits accrued for the Transferred Participants. The Plan is a continuation of and successor to the Timken Plan solely with respect to
the Transferred Participants. Any election, waiver, consent, or designation made by a Participant or a Beneficiary under the Timken Plan prior to the Spin-Off Date that was recognized as valid by the Timken Plan immediately prior to the Spin-Off
Date will be recognized by this Plan as a valid election, waiver, consent, or designation, as applicable. Effective as of the Spin-Off Date, the Transferred Participants will cease to be participants in the Timken Plan and shall become participants
in this plan.

 For the
purposes of the Plan, the following words and phrases shall have the meanings indicated in this Article I. Certain other words and phrases are defined throughout the Plan and shall have the meaning so ascribed to them.

credited with Unvested Excess Core Contributions deferred (or deemed deferred) by a Participant. A separate subaccount shall be maintained for Incentive Compensation payable in the form of Common Shares. Certain Participants may also have a separate

(a) a “Pre-2005 Subaccount” for amounts deferred by a Participant as of December 31, 2004 (and earnings and losses thereon) as determined under Treasury Regulation Section 1.409A-6(a) or any successor provision, and
(b) a “Post-2004 Subaccount” for amounts deferred for purposes of Section 409A of the Code by a Participant after December 31, 2004 (and earnings and losses thereon). Amounts in the Pre-2005 Subaccounts are intended to
qualify for “grandfathered” status pursuant to Treasury Regulation Section 1.409A-6(a) and therefore they shall be subject to the terms and conditions specified in the Timken Plan as in effect prior to January 1, 2005 which shall

 1.
Eligibility. An Eligible Employee may make an annual Deferral Election to defer receipt of all or a specified part of his or her Base Salary, Incentive Compensation, or Vested or Unvested Excess Core Contributions for any Deferral Period in
accordance with Section 2 of this Article. Subject to Section 3(iv) of this Article, an Eligible Employee who makes a Deferral Election must also make a Payment Election with respect to the amount deferred in accordance with Section 3
of this Article. An Eligible Employee’s entitlement to defer shall cease on the last day of the Deferral Period in which he or she ceases to be an Eligible Employee. 

2. Deferral Elections. All Deferral Elections, once effective, shall be irrevocable, shall be made on an Election Agreement filed with
the Vice President – Total Rewards of the Company (or other Company administrative representative as may be designated by the Vice President – Total Rewards), and shall comply with the following requirements: 

(i) The Deferral Election on the Election Agreement shall specify the percentage or the dollar amount of a Participant’s
Base Salary, Incentive Compensation and/or Excess Core Contributions that is to be deferred. 
 (ii) The Deferral Election
shall be made by, and shall be effective as of, the applicable Election Filing Date, except as provided in the following clauses (1), (2), or (3): 

(1) To the extent permitted by Section 409A of the Code, the Company may permit Eligible Employees to make a Deferral
Election with respect to 

  
 - 11 - 








 
Incentive Compensation that constitutes “performance-based compensation” (within the meaning of Section 409A(a)(4)(B)(iii) of the Code) at a time later than the Election Filing
Date but no later than the Incentive Filing Date, and in such event, the Deferral Election shall be effective as of such Incentive Filing Date. If Incentive Compensation with respect to which an Eligible Employee has made a Deferral Election under

(2) An employee who first becomes an Eligible Employee during the course of a Year, rather than as of the applicable Election
Filing Date, may make a Deferral Election with respect to Base Salary, Incentive Compensation and/or Excess Core Contributions within thirty days following the date the employee first becomes eligible to participate in the Plan. Such Deferral
Election shall be effective on the date made and, unless Section 2(ii)(1) or 2(ii)(3) applies, shall be effective with regard to Base Salary, Incentive Compensation and/or Excess Core Contributions (whichever is elected for deferral by the
Participant) earned during such Year following the filing of the Election Agreement with the Company, as determined pursuant to the pro-ration method permitted under Section 409A of the Code. For purposes of the preceding sentence, where an
individual has ceased being eligible to participate in the Plan (other than the accrual of earnings), 

  
 - 12 - 








 
regardless of whether all amounts deferred under the Plan have been paid, and subsequently becomes eligible to participate in the Plan again, the individual shall be treated as being initially

participate in the Plan. 
 (3) To the extent permitted by Section 409A of the Code, the Company may permit an Eligible

which the Eligible Employee makes such Deferral Election. In such event, the Deferral Election shall be effective as of such Forfeitable Rights Filing Date. If a Forfeitable Right with respect to which an Eligible Employee has made a Deferral
Election under this Section 2(ii)(3) becomes nonforfeitable upon death, disability (as defined in Treasury Regulation Section 1.409A-3(i)(4)), or a change in control event (as defined in Treasury Regulation Section 1.409A-3(i)(5))
prior to the 12-month anniversary of the date on which the Eligible Employee made such Deferral Election, such Deferral Election will only be given effect if the Deferral Election could have been made pursuant to a provision of the Plan other than

Employee with less than three Years of Service as of the date of an Excess Core Contribution shall elect (or, in the absence of a properly filed Election Agreement, shall

filed hereunder).

 - 14 -

(1) A Participant may elect to receive payment in one of the following forms: (A) a single, lump sum payment; (B) in

Employee fails to file properly an Election Agreement, the Eligible Employee nevertheless shall be deemed as if the Eligible Employee had timely filed an Election Agreement electing a lump sum
payment to be made within 2  1⁄2 months after the close of the Year during which the Eligible Employee achieved three Years of Service, or if earlier, the
close of the Year during which the Eligible Employee 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). 

(v) Subject to Section 3(iv) of this Article, if the Payment Elections are not made by the applicable Election Filing

less than $5,000, then the amount of the Participant’s Aggregate Account Balance may, at the discretion of the Company, be paid in a lump sum. 

7. Accelerations. Notwithstanding the foregoing provisions of this Article II: 

(i) If a Change in Control occurs, the amount of each Participant’s Post-2004 Base Salary Subaccount, Post-2004 Incentive
Compensation Subaccount, and Post-2004 Vested Excess Core Contribution Subaccount that was deferred pursuant to an election made after the Spin-Off Date, in each case including earnings and losses thereon and Common Shares received with respect to
Timken Shares included therein, shall immediately be paid to the Participant in the form of a single, lump sum payment. With respect to amounts in a Participant’s Post-2004 Subaccounts that were deferred pursuant to an election made prior to
the Spin-Off Date (including earnings and losses thereon and Common Shares received with respect to Timken Shares included therein) (the “Pre-Spin Deferrals”), if a Timken Change in Control (as defined in Appendix A) occurs, such amounts
shall immediately be paid to the Participant in the form of a single, lump sum payment. Notwithstanding any provision of this Plan to the contrary, if a Change in Control or a Timken Change in Control does not constitute a “change in the
ownership or effective control” or a “change in the ownership of a substantial portion of the assets” of 

  
 - 21 - 








 
a relevant corporation within the meaning of Section 409A(a)(2)(A)(v) of the Code and Treasury Regulation Section 1.409A-3(i)(5), or any successor provision, then payment shall be made,
to the extent necessary to comply with the provisions of Section 409A of the Code, to the Participant on the date (or dates) the Participant would otherwise be entitled to a distribution (or distributions) in accordance with the provisions of
the Plan. 
 (ii) Upon the earlier to occur of (1) a Change in Control that involves a transaction that was not approved
by the Board, and was not recommended to the Company’s shareholders by the Board, (2) a declaration by the Board that the trust (the “Trust”) established by and between the Company and a trustee (the “Trustee”), should
be funded in connection with a Change in Control that involves a transaction that was approved by the Board, or was recommended to shareholders by the Board, or (3) a declaration by the Board that a Change in Control is imminent, the Company
shall promptly to the extent it has not previously done so, and in any event within five (5) business days: 
 (A)
transfer to the Trustee to be added to the principal of the Trust a sum equal to the Pre-Spin Deferrals for all Participants under this Plan (together with an additional amount to cover all estimated administration expenses associated with the
payment of such Pre-Spin Deferrals). The payment of the Pre-Spin Deferrals or other payment by the Trustee pursuant to the Trust shall, to the extent thereof, discharge the Company’s obligation to pay the Pre-Spin Deferrals or other payment
hereunder, it being the intent of the Company that assets in such Trust be held as security for the Company’s obligation to pay the Pre-Spin Deferrals and other payments under this Agreement; and 

(B) transfer to the Trustee to be added to the principal of the Trust the sum authorized by the members of the Committee from
time to time. 

  
 - 22 - 








 Notwithstanding any provision of this Plan to the contrary, no amounts shall be transferred to
the Trustee with respect to the Trust for payments of any amount under this Plan if, pursuant to Section 409A(b)(3)(A) 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. 
 (iii) In the event of an Unforeseeable Emergency and at the request of a Participant or
Beneficiary, the Committee may in its sole discretion accelerate the payment to the Participant or Beneficiary of all or a part of his or her Account(s). Payments of amounts as a result of an Unforeseeable Emergency may not exceed the amount
necessary to satisfy such Unforeseeable Emergency plus amounts necessary to pay taxes reasonably anticipated as a result of the distribution(s), after taking into account the extent to which the hardship is or may be relieved through reimbursement
or compensation by insurance or otherwise by liquidation of the Participant’s assets (to the extent the liquidation of such assets would not itself cause severe financial hardship). 

8. Adjustments. The Committee may make or provide for such adjustments in the numbers of Common Shares or Timken Shares credited to
Participants’ Account, and in the kind of shares so credited, as the Committee in its sole discretion, exercised in good faith, may determine is equitably required to prevent dilution or enlargement of the rights of Participants that otherwise
would result from (i) any stock dividend, stock split, combination of shares, recapitalization or other change in the capital structure of the Company or The Timken Company, or (ii) any merger, consolidation, spin-off, split-off, spin-out,
split-up, reorganization, 

  
 - 23 - 








 
partial or complete liquidation or other distribution of assets, issuance of rights or warrants to purchase securities, or (iii) any other corporate transaction or event having an effect
similar to any of the foregoing. Moreover, in the event of any such transaction or event, the Committee, in its discretion, may provide in substitution for any or all Common Shares or Timken Shares deliverable under the Plan such alternative
consideration as it, in good faith, may determine to be equitable in the circumstances. 
 9. Fractional Shares. The Company shall
not be required to issue any fractional Common Shares pursuant to the Plan. The Committee may provide for the elimination of fractions or for the settlement of fractions in cash. 

ARTICLE III 

ADMINISTRATION 
 1.
Administration. The Company, through the Committee, shall be responsible for the general administration of the Plan and for carrying out the provisions hereof. The Committee shall have all such powers as may be necessary to carry out the
provisions of the Plan, including the power to (i) determine all questions relating to eligibility for participation in the Plan and the amount in the Account or Accounts of any Participant and all questions pertaining to claims for benefits
and procedures for claim review, (ii) resolve all other questions arising under the Plan, including any questions or construction, and (iii) take such further action as the Company shall deem advisable in the administration of the Plan.

authorized to adopt rules or regulations deemed necessary or appropriate in connection therewith to anticipate and/or comply with the requirements thereof (including any transition rules thereunder). 

  
 - 24 - 








 2. Claims Procedures. Whenever there is denied, whether in whole or in part, a claim for
benefits under the Plan filed by any person (herein referred to as the “Claimant”), the Committee shall transmit a written notice of such decision to the Claimant within 90 days of receiving the claim from the Claimant, which notice shall
be written in a manner calculated to be understood by the Claimant and shall contain a statement of the specific reasons for the denial of the claim, a reference to the relevant Plan provisions, a description and explanation of additional
information needed, and a statement advising the Claimant that, within 60 days of the date on which he or she receives such notice, he or she may obtain review of such decision in accordance with the procedures hereinafter set forth. Within such
60-day period, the Claimant or the Claimant’s authorized representative may request that the claim denial be reviewed by filing with the Committee a written request therefor, which request shall contain the following information: 

(i) the date on which the Claimant’s request was filed with the Committee; provided, however, that the date
on which the Claimant’s request for review was in fact filed with the Committee shall control in the event that the date of the actual filing is later than the date stated by the Claimant pursuant to this paragraph; 

(ii) the specific portions of the denial of the claim which the Claimant requests the Committee to review; 

(iii) a statement by the Claimant setting forth the basis upon which the Claimant believes the Committee should reverse the
previous denial of the Claimant’s claim for benefits and accept the claim as made; and 
 (iv) any written material
(offered as exhibits) which the Claimant desires the Committee to examine in its consideration of the Claimant’s position as stated pursuant to clause (iii) above.

fair review of the decision denying the Claimant’s claim for benefits. Within 60 days of the date of such hearing, the Committee shall render its written decision on review, written in a manner calculated to be understood by the Claimant and
including the reasons and Plan provisions upon which its decision was based, a statement that the Claimant is entitled to receive, upon request and free of charge, reasonable access to and copies of all documents and other information relevant to
the claim, and a statement describing the Claimant’s right to bring an action under Section 502(a) of ERISA. 
 ARTICLE IV 

AMENDMENT AND TERMINATION 

The Company reserves the right to amend or terminate the Plan at any time by action of the Board or its delegate; provided,
however, that no such action 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 8(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.

 ARTICLE V 

MISCELLANEOUS 
 1.
Non-alienation of Deferred Compensation. Except as permitted by the Plan and subject to Section 8(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 Employees of Subsidiaries. An Eligible Employee who is employed
by a Subsidiary and elects to participate in the Plan shall participate on the same basis as an employee 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 Employee. Except as otherwise provided in Section 7(ii) of Article II, 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 The Timken Company to make payments in the form of
Timken 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 The Timken Company under the Plan to make payment of
amounts reflected in a Timken Shares Subaccount merely constitutes the unsecured promise of The Timken Company to make payments in the form of its Timken Shares, as provided herein, and no Participant or Beneficiary shall have any interest in, or a
lien or prior claim upon, any 

  
 - 27 - 








 
property of The Timken Company. 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 Employees 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.
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. 
 6. 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. 

  
 - 28 - 








 7. Relationship to Other Plans. 

(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 (Shares
Available Under the Plans) and for purposes of the corresponding provisions of any other such plan. 
 (ii) The issuance or
transfer of Timken Shares pursuant to the Plan shall be made by The Timken Company and shall be subject in all respects to the terms and conditions of The Timken Company Long-Term Incentive Plan(s) and any other such plan. Without limiting the
generality of the foregoing, Timken Shares credited to the Timken Shares Subaccount of Participants pursuant to the Plan as Incentive Compensation shall be taken into account for purposes of Section 3 of The Timken Company Long-Term Incentive
Plans (Shares Available Under the Plans) and for purposes of the corresponding provisions of any other such plan. 
 8. Compliance with
Section 409A of the Code. 
 (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 

  
 - 29 - 








 
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 Timken 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. 

(iii) Notwithstanding any provision of the Plan to the contrary, in light of the uncertainty with respect to the proper
application of Section 409A of the Code, the Company reserves the right to make amendments to the Plan as the Company deems necessary or desirable to avoid the imposition of taxes or penalties under Section 409A of the Code. In any case, a
Participant shall be solely responsible and liable for the satisfaction of all taxes and penalties that may be imposed on a Participant or for a Participant’s Account in connection with the Plan (including any taxes and penalties


  
 - 30 - 








 
under Section 409A of the Code), and neither the Company nor any of its affiliates shall have any obligation to indemnify or otherwise hold a Participant harmless from any or all of such
taxes or penalties. 
 9. Headings; Interpretation. 

(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. 

(iii) For purposes of the Plan, the phrase “permitted by Section 409A of the Code,” or words or phrases of
similar import, shall mean that the event or circumstance that may occur or exist only if permitted by Section 409A of the Code would not cause an amount deferred or payable under the Plan to be includible in the gross income of a Participant
or Beneficiary under Section 409A(a)(1) of the Code.
