HOWMET AEROSPACE HOURLY RETIREMENT SAVINGS PLAN
AS AMENDED AND RESTATED
EFFECTIVE JANUARY 1, 2021
HISTORY AND PURPOSE
The Howmet Aerospace Hourly Retirement Savings Plan (the "Plan") is maintained for the exclusive benefit of eligible employees of Howmet Aerospace Inc. and its subsidiaries who are paid on an hourly basis, including both collectively bargained and non-bargained employee populations. The Plan is a defined contribution, individual account plan which incorporates an Internal Revenue Code Section 401(k) wage reduction arrangement, intending to qualify under Section 401(a) of the Internal Revenue Code, for the exclusive benefit of its eligible employees.
Prior to January 1, 1993, the Plan was known as the Alcoa Pre-Tax Savings Plan for Bargaining Employees. It had been initially adopted effective July 3, 1986, and was subsequently amended and restated from time to time thereafter, as described in Schedule A.
Effective January 1, 2011, the Plan was renamed the Alcoa Retirement Savings Plan for Bargaining Employees. Effective January 1, 2015, the Plan was amended and restated to incorporate provisions of Plan amendments adopted and new laws and regulations that have come into effect since the January 1, 2010, amendment and restatement of the Plan.
Effective August 1, 2016, in anticipation of the separation of Alcoa Inc., Alcoa USA Corp. established the Retirement Savings Plan for Hourly Employees of Alcoa USA Corp. (“Alcoa USA Plan”), and the accounts attributable to all Participants who were employees or former employees at the locations identified on Schedules C-1, C-2 were spun off to the Alcoa USA Plan. Effective August 1, 2016, this Plan was renamed as Arconic Bargaining Retirement Savings Plan. No person is entitled to a benefit under both plans.
In anticipation of its separation into two separate publicly-traded companies, effective January 1, 2020, immediately after the transfer of assets and liabilities attributable to salaried employees and former salaried employees held in the Arconic Fastener Systems and Rings Retirement Savings Plan to the Arconic Salaried Retirement Savings Plan, Arconic Inc. (a) merged the Arconic Fastener Systems and Rings Retirement Savings Plan with and into the Arconic Hourly Non-Bargaining Retirement Savings Plan, (b) merged the Arconic Hourly Non-Bargaining Retirement Savings Plan with and into this Plan. The Arconic Hourly Non-Bargaining Retirement Savings Plan ceased to exist as of 11:59 p.m. on December 31, 2019. The Plan was renamed the Arconic Hourly Retirement Savings Plan, effective January 1, 2020.
Effective February 1, 2020, in anticipation of its separation into two separate publicly-traded companies, Arconic Rolled Products Corporation established the Arconic Corp. Hourly 401(k) Plan, and the accounts attributable to all Participants who were employees or former employees at the locations identified on Schedules C-3 and C-4 were spun off to the Arconic Corp. Hourly 401(k) Plan. No person is entitled to a benefit under both plans.

Howmet Aerospace Hourly Retirement Savings Plan
Amended and Restated Effective as of January 1, 2021

Effective February 1, 2020, this Plan was renamed as the Howmet Aerospace Hourly Retirement Savings Plan.
Effective January 1, 2021, the Plan is hereby amended and restated again to incorporate provisions of prior Plan amendments adopted since the January 1, 2015, restatement of the Plan as well as to reflect new laws and regulations that have come into effect since the January 1, 2015, restatement of the Plan.
The Plan is the survivor plan as the result of mergers with several Subsidiaries' plans. Schedule A attached hereto contains the details and provisions related to such mergers.
The Plan is intended to be construed in accordance with any regulatory guidance issued with respect to such new laws and regulations.
Effective January 1, 2002 the Alcoa Stock Fund was replaced with an employee stock ownership plan, within the meaning of Section 4975(e) of the Code. The assets held in the ESOP must be invested primarily in employer securities as defined in Code Section 409(l). Effective November 1, 2016, Alcoa Inc. separated into two separate publicly traded companies. Alcoa Inc. was renamed Arconic Inc. and began trading under the ticker symbol ARNC. Alcoa Corporation was spun off from Arconic Inc. and began trading under the ticker symbol AA. This corporate action resulted in two separate stock funds under the Plan: the Arconic Stock Fund (which is an ESOP invested primarily in employer securities) and the Alcoa Corporation Stock Fund (a non-employer stock fund). The Alcoa Corporation Stock Fund was liquidated approximately one year after its establishment. Effective April 1, 2020, Arconic Inc. separated into two-separate publicly traded companies. Arconic Inc. was renamed Howmet Aerospace Inc. and began trading under the ticker symbol HWM. Arconic Corporation was spun off from Arconic Inc. and began trading under the ticker symbol ARNC. This corporate action resulted in two separate stock funds under the Plan: the Howmet Aerospace Stock Fund (which is an ESOP invested primarily in employer securities) and the Arconic Corporation Stock Fund (a non-employer stock-fund). ). The Arconic Corporation Stock Fund will be liquidated approximately one year after its establishment.

The value of any delisted stock that is no longer publicly traded but that is held in the Participant’s Brokerage Account shall not be considered for purposes of the preceding valuation. Any such delisted stock shall be distributed in-kind where the value of the Participant's vested account balances (not including Rollover Contributions) in all qualified defined contribution plans of Howmet Aerospace, the Subsidiaries and Affiliates is less than five thousand dollars ($5,000), in a direct rollover to an individual retirement account designated by the Benefits Management Committee.

The Trustee will invest all Savings and other amounts to be invested in the Fixed Income Fund in accordance with such directions.
(2) Accounting for Participant's Accounts. Participants' investments in the Fixed Income Fund are accounted for on a unit basis. The Trustee allocates to the accounts of each Participant such units in the Fixed Income Fund as may be acquired with funds (if any) in such Participant's accounts to be invested therein. Such allocations will be made in a uniform manner as determined by the Benefits Investments Committee. Transfers and withdrawals are valued based on the Current Market Value per unit on the Effective Date of the transfer or withdrawal.
(e) (1) Acquisition of Company Stock by Trustee. The Savings, Participating Employer Contributions, Negotiated Deferral Contributions, Discretionary Contributions, Restricted Discretionary Contributions, and Employer Retirement Income Contributions to be invested in the Howmet Aerospace Stock Fund are used by the Trustee to purchase from time to time shares of Company Stock (i) from Howmet Aerospace, at the Current Market Value thereof, or (ii) to the extent Howmet Aerospace does make shares available for purchase by the Trustee for such purpose, on the open market unless Howmet Aerospace otherwise directs, or (iii) by the exercise of warrants or rights as provided in this Section. The Trustee, to the extent reasonable, invests any cash held in the fund in cash equivalents (including commercial paper). The Trustee also holds for the purpose of allocation to the accounts of individual Participants as hereinafter provided (i) shares of such stock which the Trustee has acquired upon withdrawal by a Participant, and (ii) shares of such stock which the Trustee has acquired pursuant to Participants’ elections to transfer investments under the provisions of Section 9. All shares of such stock purchased by the Trustee are carried in the accounts of the Trustee at the actual cost thereof, including any taxes, commissions, etc. which are not paid by the Participating Employer, incident to the purchase except that shares acquired upon the exercise of warrants or rights are carried at the Current Market Value of such shares on the date of such exercise.
(2) Allocation of Stock to Participants' Accounts. Participants' investments in the Howmet Aerospace Stock Fund are accounted for on a unit basis. The Trustee allocates to the accounts of each Participant such units in the Howmet Aerospace Stock Fund as may be acquired with funds (if any) in such Participants' accounts to be invested therein. Such allocations are made in a uniform manner as determined by the Benefits Investments Committee. Transfers and withdrawals are valued based on the Current Market Value per unit on the Effective Date of the transfer or withdrawal.
(3) Allocation of Dividends to Participants' Accounts. In valuing the units, dividends are accounted for on the date the Board declares the dividend. Once received, dividends are invested in the Howmet Aerospace Stock Fund. A Participant may elect to receive an annual distribution of the dividends posted to their account during the Plan Year.

(7) Separation of Alcoa Inc. and Creation of Arconic and Alcoa Corporation Stock Funds. Effective November 1, 2016, Alcoa Inc. separated into two separate publicly traded companies. Alcoa Inc. was renamed Arconic Inc. and began trading under the ticker symbol ARNC. Alcoa Corporation was spun off from Arconic Inc. and began trading under the ticker symbol AA. This corporate action resulted in two separate stock funds under the Plan: the Arconic Stock Fund (which is an ESOP invested primarily in employer securities) and the Alcoa Corporation Stock Fund (a non-employer stock fund). The Alcoa Corporation Stock Fund shall be permitted as an investment option under the Plan only for approximately one (1) year after November 1, 2016. The final liquidation date will be determined by the Committee in its sole and absolute discretion. No new investments or purchases may be made in the Alcoa Corporation Stock Fund on or after November 1, 2016. Notwithstanding the foregoing, all dividends under the Alcoa Corporation Stock Fund shall be reinvested in the Alcoa Corporation Stock Fund until its liquidation. Nothing herein shall be interpreted to prevent a Participant from acquiring Alcoa Corporation stock under the Brokerage Account.
(8) Separation of Arconic Inc. and Creation of Howmet Aerospace Inc. and Arconic Corporation Stock Funds. Effective April 1, 2020, Arconic Inc. separated into two separate publicly traded companies. Arconic Inc. was renamed Howmet Aerospace Inc. and began trading under the ticker symbol HMW. Arconic Corporation was spun off from Arconic Inc. and began trading under the ticker symbol ARNC.

(f) (1) Acquisition of Other Investments by Trustee. Howmet Aerospace has and in the future will enter into investment arrangements with various investment managers. Any such arrangements must be approved by the Benefits Investments Committee. Expenses incurred in connection with the purchase or sale of securities by the investment manager are paid from the applicable Investment Fund.
(2) Accounting for Participant's Accounts. Participants' investments in the Core Funds are accounted for on a unit basis. The Trustee allocates to the accounts of each Participant such units in each of the Core Funds as may be acquired with funds (if any) in such Participant's accounts to be invested therein. Such allocations will be made in a uniform manner as determined by the Benefits Investments Committee.

Pre-Tax Savings, After-Tax Savings, Rollover Contributions, Participating Employer Contributions, Negotiated Deferral Contributions, Discretionary Contributions, Restricted Discretionary Contributions, and Employer Retirement Income Contributions that are subject to transfer as provided in Section 9, may not be directly invested in the Brokerage Account, nor may withdrawals, distributions or loans be made directly from the Brokerage Account.

Trades may be subject to initial and subsequent investment minimums required by a mutual fund.
Transfers are made out of the Brokerage Account and into the Core Funds from the Schwab money market fund.

(3) Expenses Incurred by Trading and Voting. The Broker’s standard commission schedule will be deducted from the Brokerage Account of the Participant who initiates the trades, and any other fees and expenses incurred through the Brokerage Account will be paid directly by the Participant.
The Broker will execute proxies for any securities held in the Brokerage Account in accordance with written directions of any Participant.

In the event that assets are transferred to this Plan from any other plan sponsored by Howmet Aerospace or any Subsidiary or Affiliate, each Participant who has assets transferred from such plan or plans will be entitled to a benefit under this Plan which is equal to or greater than the benefit he or she had under such other plan.

a Participant's waiver if the Participant establishes to the satisfaction of a Plan representative that spousal consent cannot be obtained because the spouse cannot be located or because of other circumstances set forth in Code Section 401(a)(11) and Treasury Regulations issued thereunder. Any written consent given or deemed to have been given by a Participant's spouse hereunder shall be irrevocable and shall be effective only with respect to such spouse and not with respect to any subsequent spouse. In addition, with regard to a Participant's waiver of the Qualified Joint and Survivor Annuity form of distribution, the spouse's written consent must either (a) specify the form of distribution elected instead of the Qualified Joint and Survivor Annuity, and that such form may not be changed (except to a Qualified Joint and Survivor Annuity) without written spousal consent or (b) acknowledge that the spouse has the right to limit consent as provided in clause (a) above, but permit the Participant to change the form of distribution elected without the spouse's further consent.
