The Plan&#8217;s sponsor is Allegheny Technologies Incorporated (ATI, the Plan Sponsor, or the Company).  Eligible participants in the Plan consist of employees with defined contribution benefits that are provided in accordance with collectively bargained labor agreements across all of ATI&#8217;s U.S. operations.  The Plan is a multiple employer plan and includes represented employees of a 50% owned ATI joint venture, A&#38;T Stainless.  The following brief description of the Plan is provided for general information purposes only.  Participants should refer to the summary plan description for more complete information regarding eligibility, vesting, contributions, and withdrawals.</font></div><div style="margin-top:9pt"><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The purpose of the Plan is to provide retirement benefits to eligible employees through company contributions, and to encourage employee thrift by permitting eligible employees to defer a part of their compensation and contribute such deferrals to the Plan.  The Plan allows employees to contribute a portion of eligible wages each pay period through payroll deductions subject to Internal Revenue Code (the Code) limitations.  Unless otherwise specified by the participant, contributions are invested in the Qualified Default Investment Alternative, which is the Vanguard Target Retirement Fund that most closely matches the participant&#8217;s 65</font><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:6.5pt;font-weight:400;line-height:120%;position:relative;top:-3.5pt;vertical-align:baseline">th</font><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"> birthday date. </font></div><div style="margin-top:9pt"><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">For certain employees in the Plan, qualifying employee contributions are matched by the respective employing companies that are affiliates of ATI based on various formulas including as a percentage of employee contributions, or as a flat dollar amount which can be based on years of service.  Employees at certain ATI operations receive an employer contribution to the Plan based on hours worked or at the discretion of the operation&#8217;s Board of Directors based on its current or accumulated profits for the Plan year.  The specific conditions, amounts and criteria governing eligibility for the various employer contributions are set forth in the Plan documents or individual bargaining agreements.  The Plan allows participants to direct their contributions, and contributions made on their behalf to any of the investment options offered by the Plan. </font></div><div style="margin-top:9pt"><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Participants are vested immediately in their contributions plus actual investment performance thereon.  Many employees in the Plan are immediately vested in all Company contributions.  For certain employees, vesting in the Company&#8217;s contributions varies based on employee group classification and&#47;or years of service not to exceed 6 years.  Participant forfeitures are used to reduce future employer contributions or in the absence of such contributions, are distributed equally to certain Plan participants.   </font></div><div style="margin-top:9pt"><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Separate accounts are maintained by the Plan Sponsor for each participating employee.  Participants may make &#8220;in-service&#8221; and hardship withdrawals as outlined in the plan document.  On March 27, 2020,&#160;the Coronavirus Aid, Relief, and Economic Security Act (CARES Act)&#160;was signed into law which provided both plan sponsor and&#160;participant relief.  ATI voluntarily adopted various provisions from the CARES Act as they related to the Plan effective May 8, 2020.  The CARES Act created a new kind of in-service withdrawal option for people who are facing economic challenges related to COVID-19.  Effective May 8, 2020, participants may withdraw up to $100,000 from the Plan without being required to pay the normal 10% penalty for early withdrawal if the participant is under age 59&#189;.  Participants have an extended period of three years to pay the ordinary income taxes on that distribution.  Also, participants may choose to make a repayment to their Plan account of any COVID-related distributions within three years.  Prior to January 1, 2020, participants making hardship withdrawals were not permitted to contribute to the Plan for 6 months after the date of the hardship withdrawal. </font></div><div style="margin-top:9pt"><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">For employees and retirees at least age 70&#189; (or age 72 in 2020), the CARES Act waived required minimum distributions from the plan for the 2020 calendar year.  As a result, automatic payments scheduled for December 2020 were not made.  If a participant was required to receive a payment by the end of the year and they still wanted to receive it, they were able to request it.</font></div><div style="margin-top:9pt"><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Active employees can borrow up to 50% of their vested account balances minus any outstanding loans.  The loan amounts are further limited to a minimum of $1,000 and a maximum of $50,000, and an employee can obtain no more than three loans at one time.  Interest rates are determined based on commercially accepted criteria, and payment schedules vary based on the type of the loan.  General-purpose loans are repaid over 6 to 60 months, and primary residence loans are repaid over periods up to 180 months.  Principal and interest payments are made by payroll deductions.  Effective May 8, 2020 under the CARES Act,  participants that had an existing loan from the Plan or took a new loan that had a first repayment date on or before December 31, 2020, were permitted to delay repaying the loan for 12 continuous months.  Participants that elected this option cannot begin loan repayment before the 12-month period has ended. </font></div><div style="height:42.75pt;position:relative;width:100%"><div style="bottom:0;position:absolute;width:100%"><div style="text-align:center"><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">4</font></div></div></div><hr style="page-break-after:always"><div style="min-height:42.75pt;width:100%"><div><font><br></font></div></div><div style="margin-top:9pt"><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">All expenses incurred in the administration of the Plan, including those charged by the Plan&#8217;s trustees are paid by the Plan, except as paid for or reimbursed by the Company.

diversified portfolio of guaranteed investment contracts including synthetic investment contracts, separate account contracts, cash and cash equivalents, and other instruments that can be carried at

All of these assets allow participant-directed transactions to be made at contract value.  The assets underlying the synthetic investment contracts may include U.S. Treasury bonds, agency bonds, corporate bonds, residential mortgage backed securities, asset-backed securities, commercial mortgage-backed securities, and common collective trusts.  These assets are owned by the Plan.

In addition to market information, models may also incorporate transaction details, such as maturity.  Valuation adjustments, such as liquidity valuation adjustments, may be necessary when the Plan is unable to observe a recent market price for a financial instrument that trades in inactive (or less active) markets.
