ATI Inc.
Dallas, Texas
Opinion on the Financial Statements
We have audited the accompanying statements of net assets available for benefits of The ATI Retirement Plan (the Plan) as of December 31, 2024 and 2023, and the related statement of changes in net assets available for benefits for the year ended December 31, 2024, and the related notes (collectively referred to as the financial statements). In our opinion, the financial statements present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2024 and 2023, and the changes in net assets available for benefits for the year ended December 31, 2024 in conformity with accounting principles generally accepted in the United States of America.
Basis for Opinion
These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on the Plan’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Plan in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.
Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
Supplemental Information
The accompanying schedule of assets (held at end of year) as of December 31, 2024 has been subjected to audit procedures performed in conjunction with the audit of the Plan’s financial statements. The supplemental information is the responsibility of the Plan’s management. Our audit procedures included determining whether the supplemental information reconciles to the financial statements or the underlying accounting and other records, as applicable, and performing procedures to test the completeness and accuracy of the information presented in the supplemental information. In forming our opinion on the supplemental information, we evaluated whether the supplemental information, including its form and content, is presented in conformity with the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. In our opinion, the supplemental information is fairly stated, in all material respects, in relation to the financial statements as a whole.

The ATI Retirement Plan
Notes to Financial Statements
December 31, 2024
1. Description of the Plan
The ATI Retirement Plan (the Plan) is a defined contribution plan and is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). The Plan’s sponsor is ATI Inc. (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’s U.S. operations. The Plan is a multiple employer plan and includes represented employees of a 50% owned ATI joint venture, A&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.
The purpose of the Plan is to provide retirement benefits to eligible employees through company contributions, and to encourage employees to save for retirement by permitting eligible employees to defer a part of their compensation and contribute such deferrals to the Plan. Amounts up to 80% of a participant’s compensation, as defined in the Plan agreement, can be contributed by the participant in any combination of after-tax and before-tax contributions for each period, subject to limitations imposed by the Internal Revenue Code ($23,000 for calendar year 2024). Catch up contributions of $7,500 were available to participants 50 years or older in 2024. Participants are allowed to rollover existing qualified retirement funds into the Plan. The Plan allows participants to direct their contributions, and contributions made on their behalf, to any of the investment options offered by the Plan. 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’s 65th birthday year.
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. 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.
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’s contributions varies based on employee group classification and/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.
Separate accounts are maintained by the Plan Sponsor for each participating employee. Participants may make “in-service” and hardship withdrawals as outlined in the plan document. After age 59½, a participant may withdraw the vested portion of their account.
Payments of benefits are available by request upon termination due to retirement, disability, death, or other voluntary or involuntary termination of employment. Distributions can be made in the form of a lump sum or installments.
A participant can borrow the lesser of $50,000 or 50% of their account balances minus any outstanding loans. The loan amounts are further limited to a minimum of $500 and a maximum of $50,000, and an employee can obtain no more than three loans at one time. Loans are repayable through payroll deductions over periods ranging up to 60 months for general purpose loans and up to 180 months for residential loans. The interest rate is determined at the issuance of the loans and is fixed over the life of the note.
All expenses incurred in the administration of the Plan, including those charged by the Plan’s trustees are paid by the Plan, except as paid for or reimbursed by the Company. Through June 30, 2024, Benefit Trust Company was the Plan's trustee for the Company stock fund and the Plan’s trustee for all other Plan assets was AON Trust Company. Effective July 1, 2024, the Plan’s trustee for all Plan assets is Empower Trust Company. Investment related expenses are included in the master trusts as investment income/expense.

2. Significant Accounting Policies
Use of Estimates and Basis of Accounting
The preparation of financial statements in conformity with United States generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements, accompanying notes and supplemental schedule. Actual results could differ from those estimates. The financial statements are prepared under the accrual basis of accounting.
Investment Valuation
The investments in master trusts, representing the Plan’s interest in the net assets of these master trusts and investments in registered investment companies, are stated at fair value, or, for fully benefit-responsive investment contracts, at contract value. Contract value is the relevant measurement attributable to fully benefit-responsive investment contracts, because contract value is the amount participants would receive if they were to initiate permitted transactions under the terms of the Plan. The contract value represents contributions plus earnings, less participant withdrawals and administrative expenses.
The assets of the master trusts, as well as income/losses, 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 investments of the assets of the master trusts.
Purchases and sales of registered investment companies are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date. Net income from interest in registered investment companies 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.
Notes Receivable from Participants
Notes receivable from participants represent participant loans that are recorded at their unpaid principal balance plus any accrued but unpaid interest. Interest income on notes receivable from participants 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 was recorded as of December 31, 2024 or 2023. If a participant ceases to make a note repayment and the Plan administrator deems the note to be a distribution, the note receivable balance is reduced and a benefit payment is recorded.
Plan Transfers
As employee status changes, transfers of participant balances to/from the Plan occur to/from the ATI 401(k) Savings Plan, an ATI sponsored plan whose eligible participants consist of non-represented employees of ATI’s U.S. operations.

3. Investments
Certain assets of the Plan, along with the assets of another ATI sponsored plan, are part of master trust, the Allegheny Technologies Incorporated Master Trust. Effective July 1, 2024 the ATI Company Stock Fund Master Trust was terminated and assets invested in Company stock were moved to the Allegheny Technologies Incorporated Master Trust. The Plan also permits self-directed investments in registered investment companies that are maintained in accounts separate from the master trusts.

Administrative fees for the ATI Company Stock Fund Master Trust, through its terminated date, were paid by the Allegheny Technologies Incorporated Master Trust.
Investments accounted for at contract value are held by the BNY Mellon Stable Value Fund (the Fund), which may invest in a diversified portfolio of guaranteed investment contracts including synthetic investment contracts, separate account contracts,
6
cash and cash equivalents, and other instruments that can be carried at book value. 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. As of December 31, 2024, the Fund had a product allocation of 3% to cash, 5% to fixed maturity contracts and 92% to constant duration contracts.
Interest crediting rates on the contracts held in the Fund are determined at the time of purchase. Such crediting rates are reviewed and may be reset on a quarterly basis.
Typically, the investment contracts in the Fund do not have a stated final maturity, but contracts wrapping individual bonds may have a gradual tapering of duration unless new bonds are purchased within the investment contract. These contracts are referred to as “fixed maturity” contracts, while “constant duration” contracts invest in common collective trusts or actively managed accounts, managed against a stated benchmark or to a targeted duration.
Certain investment contracts in the Fund may provide for adjustment to contract value for withdrawals made prior to termination. If the Plan were deemed to be in violation of ERISA or lose its tax exempt status, among other events, the issuers of the fully benefit responsive investment contracts would have the ability to terminate the contracts and settle at an amount different from contract value.
Certain investments are subject to restrictions or limitations if the Plan Sponsor decides to entirely exit an investment. Investments in registered investment companies, common collective trusts, pooled separate accounts and the Fund may require at least 30 days prior notice to completely withdraw from the investments. The targeted date fund investments held in common collective trusts currently do not require the prior approval of the investment manager if the Plan Sponsor decides to entirely exit these investments, but prior trade date notification is necessary to effect timely securities settlement or delivery of an investment’s liquidation and transfer to another investment. The Plan had no unfunded commitments as of December 31, 2024 and 2023.
4. Fair Value Measurement
In accordance with accounting standards, fair value is defined as 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 accounting standards establish a three-level hierarchy for fair value measurements based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date.
Determination of Fair Value
Fair value is based upon quoted market prices, where available. If listed prices or quotes are not available, fair value is based upon models that primarily use, as inputs, market-based or independently sourced market parameters, including yield curves, interest rates, volatilities, equity or debt prices, foreign exchange rates and credit curves. 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. Liquidity adjustments are not taken for positions classified within Level 1 (as defined below) of the fair value hierarchy.
The methods described below may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Plan believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. There have been no changes in the methodologies used at December 31, 2024 and 2023.
Valuation Hierarchy
The three levels of inputs to measure fair value are as follows:
Level 1 – Quoted prices in active markets for identical assets and liabilities.
Level 2 – Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.
7
Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.
A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.
Valuation Methodologies
The valuation methodologies used for assets and liabilities measured at fair value, including their general classification based on the fair value hierarchy, include the following:
•Cash and cash equivalents – Where the net asset value (NAV) is a quoted price in a market that is active, it is classified within Level 1 of the valuation hierarchy.
•Corporate common stock – This investment is valued at the closing price reported on the major market on which the individual securities are traded. Common stock is classified within Level 1 of the valuation hierarchy.
•Common collective trusts – These investments are investment vehicles valued using the NAV, as a practical expedient, provided by the administrator of the fund. The NAV is based on the value of the underlying assets owned by the fund, minus its liabilities, and then divided by the number of shares outstanding.
•Registered investment companies – These investments are public investment vehicles valued using the NAV provided by the administrator of the fund. The NAV is based on the value of the underlying assets owned by the fund, minus its liabilities, and then divided by the number of shares outstanding. Where the NAV is a quoted price in a market that is active, it is classified within Level 1 of the valuation hierarchy.
•Pooled separate accounts – These investments are investment vehicles valued using the NAV, as a practical expedient, provided by the contract issuer. The NAV is based on the value of the underlying assets owned by the fund, minus its liabilities, and then divided by the number of shares outstanding.
The following tables present the financial instruments of the master trusts at fair value by caption on the statements of net assets available for benefits and by category of the valuation hierarchy (as described above) as of December 31, 2024 and 2023. The master trusts had no assets classified within Level 2 or Level 3 of the valuation hierarchy.

In addition to the Plan’s investments in the master trusts, the Plan held self-directed accounts that are invested in registered investment companies and are categorized as Level 1 assets.

5. Income Tax Status
The Plan has received a determination letter from the Internal Revenue Service (IRS) dated October 13, 2015, stating that the Plan is qualified under Section 401(a) of the Code and, therefore, the related trust is exempt from taxation. Subsequent to the effective date of the amendments addressed by the determination letter, the Plan was amended. Once qualified, the Plan is required to operate in conformity with the Code to maintain its qualification. The Plan administrator believes the Plan is being operated in compliance with the applicable requirements of the Code and, therefore, believes that the Plan, as amended, is qualified and the related trust is tax-exempt.
The Plan administrator has analyzed the tax positions taken by the Plan, and has concluded that as of December 31, 2024 and 2023, there are no uncertain positions taken or expected to be taken. The earliest tax year open to U.S. Federal examination is 2021.
6. Plan Termination
Although they have not expressed any intent to do so, the employing companies have the right under the Plan to discontinue their contributions at any time and to terminate their respective participation in the Plan subject to the provisions of ERISA. However, no such action may deprive any participant or beneficiary under the Plan of any vested right. In the event of Plan termination, participants would become 100% vested in their employer contributions.
7. Risks and Uncertainties
The Plan invests in various investment securities. Investment securities are exposed to various risk 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.
8. Party-In-Interest Transactions
At December 31, 2024 and 2023, the Plan held 438,269 and 533,655 units, respectively, of common stock of ATI, the sponsoring employer, with fair value of $28,527,659 and $28,449,474, respectively. The units held by the Plan at December 31, 2024 and 2023 reflect the Plan’s interest in the master trusts. During the year ended December 31, 2024, the Plan recorded an investment gain of $6,209,106 related to its investment in the common stock of ATI. Certain administrative functions are performed by employees of ATI at no cost to the Plan.
