TimkenSteel Corporation Savings Plan

for Certain Bargaining Employees

Notes to Financial Statements

December 31, 2017 and 2016, and Year Ended December 31, 2017

1. Description of the Plan

The following description of TimkenSteel Corporation` Savings Plan for Certain Bargaining Employees (the Plan) provides only general information. Participants should refer to the Summary Plan Description for a more complete description of the Plan’s provisions. The Plan was established effective June 30, 2014 in connection with the spinoff (spinoff) of TimkenSteel Corporation (the Company) from The Timken Company (Timken). In the spinoff, Timken transferred certain assets and liabilities relating to TimkenSteel Corporation employees and retirees to the Plan. Great West Trust Company, LLC is the trustee of the Plan (Trustee). The assets of the Plan are held in The Master Trust Agreement for the TimkenSteel Corporation Defined Contribution Plan (The Master Trust), which was established for the investment of assets of the Plan and the two other defined contribution plans sponsored by the Company.

General

The Plan is a defined contribution plan, which covers full-time hourly employees of the Company who are members of the Workers Union Local 10. Employees of the Company become eligible to participate in the Plan on the first of the month after one full calendar month of full-time employment or following completion of one year of service and 1,000 hours. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA).

Contributions

Under the provisions of the Plan, participants may elect to contribute between 1% and 75% of their eligible earnings on a pretax basis directly to the Plan subject to Internal Revenue Service (IRS) limitations. Participants are also able to contribute amounts representing distributions from other qualified defined benefit or 401(k) defined contribution plans, except Roth rollovers. The Company matches participant contributions (Company Matching Contributions) at an amount equal to 100% on the first 3% of the participant’s eligible earnings.

Upon enrollment, a participant may elect to direct his or her contribution in 1% increments to any of the Plan’s investment options. Participants have access to their account information and the ability to make changes on a daily basis, subject to the next available payroll for contribution change election, through an automated telecommunications system. Account information and certain changes may also be made through the Internet.

Notes to Financial Statements (continued)

Participant Accounts

Each participant’s account is credited with the participant’s contributions and allocations of (a) the Company’s contributions and (b) Plan earnings, and is charged an allocation of administrative expenses. Plan earnings are allocated based on the participant’s share of net earnings or losses of their respective elected investment options. Allocations of administrative expenses are based on participant’s account balance (as defined in the Plan). Forfeited balances of terminated participants’ nonvested accounts are used to reduce future Company contributions. The benefit to which a participant is entitled is the benefit that can be provided from the participant’s vested account.

Vesting

Participants are immediately vested in their contributions, rollover contributions, and Company Matching Contributions, plus actual earnings thereon.

Notes Receivable from Participants

Participants may borrow from their vested interest in their total account a minimum of $1,000 up to a maximum equal to the lesser of (1) $50,000 minus the excess of the highest outstanding loan balance during the past 12 months or (2) 50% of their total vested account balance. Loan terms generally cannot exceed five years for general purpose loans and thirty years for residential loans.

The loans are secured by the balance in the participant’s vested account and bear interest at an interest rate of 1% in excess of the prime rate the month the loan is granted, as published in the Wall Street Journal on the first business day of the month in which the loan is granted. Principal and interest are paid ratably through payroll deductions or direct payments from participants.

Payment of Benefits

Upon termination of service with the Company, participants having a vested account balance greater than $5,000 have the option of (i) transferring their account balance to another qualified plan, (ii) receiving a lump-sum amount equal to the vested balance of their account, or (iii) leaving their vested account balance in the Plan. Participants with balances between $1,000 and $5,000 may elect to receive a distribution or roll over their vested balances to another qualified plan or Individual Retirement Account. Participants having a vested account balance less than $1,000 receive a lump-sum amount equal to their vested account balance. Participants electing to leave their vested assets in the Plan may do so until age 70 ½ after which time the lump-sum or installment distribution options would apply.

Hardship withdrawals are allowed for participants incurring an immediate and severe financial need, as defined by the Plan. Hardship withdrawals are strictly regulated by the IRS.

Notes to Financial Statements (continued)

Forfeitures

Under the provisions of the Plan, when forfeitures occur, it shall be applied to pay Plan fees and expenses, to make special contribution for restoration of prior forfeitures, and reduce future Company contributions. Forfeiture balances as of December 31, 2017 and 2016 were $17 and $15, respectively.

Plan Transfers

Certain participants who change job positions within the Company and, as a result, are covered under a different defined contribution plan offered by the Company, may be eligible to transfer account balances between plans. Transfers between the Plan are subject to approval by the Plan Administrator.

Plan Termination

Although it has not expressed any interest to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, the Trustee shall distribute to each participant the balance in their separate account, which becomes fully vested at the date of Plan termination.

2. Summary of Accounting Policies

Basis of Accounting

The financial statements of the Plan have been prepared on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP).

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and changes therein, and accompanying notes and supplemental schedule. Actual results could differ from those estimates.

Investment Valuation and Income Recognition

Investments are reported at fair value. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Investment Committee determines the Plan's valuation policies. See Note 4 for discussion of fair value measurements.

5

TimkenSteel Corporation Savings Plan

for Certain Bargaining Employees

Notes to Financial Statements (continued)

The Plan's Trustee maintains common collective trust funds and a collective investment trust of common shares of TimkenSteel Corporation and a collective investment trust of common shares of the Timken Company, in which the Company’s defined contribution plans participate on a unit basis. Participation units in TimkenSteel Corporation ESOP Stock Fund and Timken Company Stock Fund are valued at net asset value.

Purchases and sales of securities are recorded on a trade-date basis. Dividends are recorded on the ex-dividend date. Interest income is recorded when received. Net appreciation includes the Plan's gains and losses on investments bought and sold as well as held during the year.

Payment of Benefits

Benefits are recorded when paid.

Expenses

Certain expenses of maintaining the Plan are paid by the Company and are therefore excluded from these financial statements. Investment-related expenses are included in net investment gain from The Master Trust Agreement for TimkenSteel Corporation Defined Contribution Plans. Fees for the administration of notes receivable from participants are included in adminstrative expenses and charged directly to the participant's account.

Notes Receivable from Participants

Participant notes receivable represents participant loans that are recorded at their unpaid principal balance plus any accrued but unpaid interest. Interest income on participants' notes receivable is recorded when it is earned. Related fees are recorded as administrative expenses and are expensed when they are incurred. No allowance for credit losses has been recorded as of December 31, 2017 or 2016. Delinquent participant loans are reclassified as distributions based upon the terms of the Plan.

New Accounting Pronouncements

In February 2017, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2017-06, Plan Accounting: Defined Benefit Pension Plans (Topic 960),Defined Contribution Pension Plans (Topic 962), Health and Welfare Benefit Plans (Topic 965), Employee Benefit Plan Master Trust Reporting. The amendments in this update require that a Plan’s interest in a master trust and any change in that interest be presented in a separate line item in the statement of net assets and in the statement of net assets available for plan benefits. The amendments in the ASU also require all plans to disclose (1) their master trust’s other asset and liability balances and (2) the dollar amount of the plan’s interest in each of those balances. The amendments in the ASU are effective for fiscal years beginning after December 15, 2018. Early adoption is permitted. The Plan is currently evaluating the impact on the net assets available for plan benefits.

Notes to Financial Statements (continued)

Evaluation of Subsequent Events

The Plan has evaluated the impact of events that have occurred subsequent to December 31, 2017, through the date the financial statements were available to be issued, for possible recognition or disclosure in those financial statements.  Based on this evaluation, other than as recorded or disclosed within the financial statements and related notes, the Plan has determined that there were no additional events that were required to be recognized or disclosed. 

3. Investments

The Plan’s assets are held in the Master Trust, commingled with assets of other Company-sponsored benefit plans.

Each participating plan’s interest in the investment funds (i.e., separate accounts) of the Master Trust is based on account balances of the participants and their elected investment funds. The Master Trust assets are allocated among the participating plans by assigning to each plan those transactions (primarily contributions, benefit payments, and plan-specific expenses) that can be specifically identified and by allocating among all plans, in proportion to the fair value of the assets assigned to each plan, income and expenses resulting from the collective investment of the assets of the Master Trust.

The following table presents the fair values of investments in the Master Trust as of December 31, 2017 and 2016:

	2017		2016
Investments, at Fair Value:

4. Fair Value Measurements

The fair value framework for measuring fair value provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1) and the lowest priority to unobservable inputs (level 3). The three levels of the fair value hierarchy under FASB Accounting Standards Codification (ASC) 820, Fair Value Measurements and Disclosures, are described as follows:

Level 1 – Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Plan has the ability to access.

9

TimkenSteel Corporation Savings Plan

for Certain Bargaining Employees

Notes to Financial Statements (continued)

Level 2 – Inputs to the valuation methodology include:

•quoted prices for similar assets or liabilities in active markets;

•quoted prices for identical or similar assets or liabilities in inactive markets;

•inputs other than quoted prices that are observable for the asset or liability;

•inputs that are derived principally from or corroborated by observable market data by correlation or other means.

If the asset or liability has a specified (contractual) term, the level 2 input must be observable for substantially the full term of the asset or liability.

Level 3 – Inputs to the valuation methodology are unobservable and significant to the fair value measurement.

The asset's or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques maximize the use of relevant observable inputs and minimize the use of unobservable inputs.

The following tables set forth by level, within the fair value hierarchy, the Master Trust's assets at fair value on a recurring basis as of December 31, 2017 and 2016:

	Assets at Fair Value as of December 31, 2017

Assets:
Registered Investment Companies	$	192,055,516	$	192,055,516	$	—	$	—

(a) In accordance with Subtopic 820-10, certain investments that were measured at net asset value per share (or its equivalent) have not been classified in the fair value hierarchy. The fair value amounts presented in this table are intended to permit reconciliation of the fair value hierarchy to the line items presented in the statements of net assets available for benefits.

TimkenSteel Corporation Savings Plan

Notes to Financial Statements (continued)

Following is a description of the valuation methodologies used for assets measured at fair value.

Registered investment companies are valued at the daily closing price as reported by the fund. The funds held by the Plan are open-ended funds that are registered with the SEC. These funds are required to publish their daily net asset value (NAV) and to transact at that price. The funds held by the Plan are deemed to be actively traded.

Common Collective Trust Funds are valued based on the NAV of units of the common collective trust. The NAV, as provided by the trustee, is used as a practical expedient to estimating fair value. The NAV is based upon the fair value of the underlying investments comprising the trust less its liabilities. The practical expedient is not used when it is determined to be probable that the fund will sell the investment for an amount different than the reported NAV. Participant transactions (purchases and sales) may occur daily. Were the Plan to initiate a full redemption of the collective trust, the investment adviser reserves the right to temporarily delay withdrawal from the trust in order to ensure that securities liquidations will be carried out in an orderly business manner.

The following tables summarize investments measured at fair value based on net asset value (NAVs) per share as of December 31, 2017 and 2016:

December 31, 2017	Fair Value		Unfunded Commitments	Redemption Frequency	Redemption Notice Period

TimkenSteel Corporation Savings Plan

Notes to Financial Statements (continued)

Investments held by the Master Trust as of both December 31, 2017 and 2016 included the following:

The JPMorgan Core Bond Funds include investments that seek to maximize total return by investing primarily in a diversified portfolio of intermediate and long-term debt securities. The fair value of the investments in these funds has been determined using the net asset value per share.

The JPMCB Equity Index - CF includes investments that provide exposure to a broad equity market and are designed to mirror the aggregate price and dividend performance of the S&P 500 Index. The fair value of the investments in this fund has been determined using the net asset value per share.

The SSgA Russell Small Cap Index NL-A includes investments seeking an investment return that approximates as closely as practicable, before expenses, the performance of the Russell 2000 Index over the long term. The fund includes exposure to stocks of small U.S. companies. The fair value of the investments in this fund has been determined using the net asset value per share.

The Wells Fargo Stable Value Funds E & W are collective investment funds that actively manage a diversified portfolio of investment contracts, and the associated portfolio of underlying assets. An investment by a plan in these funds results in the issuance of a given number of participation interests (Units) in the fund for the Plan's account. The fair value of the investments in this fund have been determined using the net asset value per share.

The TimkenSteel Corporation ESOP Fund is a collective investment fund that holds Timken Steel Corporation common stock and money market funds to provide liquidity for daily accounts. The TimkenSteel Corporation ESOP Fund consists of assets from the following sources: employee contributions (including certain rollovers), employee loan repayments, exchanges into the fund from other investment options, Company contributions (vested and unvested), earnings and dividends. The fair value of the participation units of this fund have been determined using the net asset value per share. Transactions within this fund are considered related party transactions of the Plan.

The Timken Company Stock Fund is a collective investment fund that holds Timken Company common stock and money market funds to provide liquidity for daily accounts. The Timken Company Stock Fund consists of assets from the following sources: employee contributions (including certain rollovers), employee loan repayments, exchanges into the fund from other investment options, Company contributions (vested and unvested), earnings and dividends. The fair value of the participation units of this fund have been determined using the net asset value per share. Transactions within this fund are considered related party transactions of the Plan.

5. Related-Party Transactions

Related-party transactions include investments in the TimkenSteel Corporation ESOP Fund and the Timken Company Stock Fund. Transactions involving these investments are allowable party-in-interest transactions under ERISA.

The following is a summary of transactions in the TimkenSteel Corporation ESOP Fund and the Timken Company Stock Fund with the Master Trust for the year ended December 31, 2017:

Purchased and transferred in	$	30,201,902
Sold and transferred out	$	43,133,666

Purchases and benefits paid to participants include TimkenSteel Corporation common shares valued at quoted market prices at the date of purchase or distribution.

12

TimkenSteel Corporation Savings Plan

for Certain Bargaining Employees

Notes to Financial Statements (continued)

Certain legal and accounting fees and certain administrative expenses relating to the maintenance of participant records are paid by The Company. Fees paid during the year for services rendered were based on customary and reasonable rates for such services.

6. Income Tax Status

The IRS has determined and informed the Plan Administrator, by a letter dated May 31, 2016, that the Plan and related trust are designed in accordance with applicable sections of the Internal Revenue Code (IRC). The Plan has been amended since then, but the Plan Administrator and the Plan's legal counsel believe that the Plan is designed, and is currently being operated, in compliance with the applicable requirements of the IRC and therefore, believe that the Plan is qualified, and the related trust is tax-exempt.

U.S. GAAP requires Plan management to evaluate tax positions taken by the Plan and recognize a tax liability or asset if the Plan has taken an uncertain position that more likely than not would not be sustained upon examination by the IRS. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress. The Plan Administrator has analyzed the tax positions taken by the Plan, and has concluded that, as of December 31, 2017, there are no uncertain positions taken or expected to be taken. The Plan has recognized no interest or penalties related to uncertain tax positions.

7. Risks and Uncertainties

The Master Trust invests in various investment securities. Investment securities are exposed to various risks such as interest rate, market and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect participants’ account balances and the amounts reported in the statements of net assets available for benefits.
