Rhea-AI Filing Summary

ATI Inc. (NYSE: ATI) reported Q2 FY25 results for the 13-week period ended 29-Jun-25. Sales rose 4 % YoY to $1.14 bn, driven by 9 % growth in High Performance Materials & Components (HPMC, $609 m) that offset flat Advanced Alloys & Solutions (AA&S, $532 m). Gross profit increased 7 % to $242 m; gross margin expanded 10 bps to 21.3 %. Operating income advanced 13 % to $161 m (14.1 % margin). Net income attributable to ATI jumped 23 % to $101 m, lifting diluted EPS to $0.70 versus $0.58.

Year-to-date sales grew 6.9 % to $2.29 bn and diluted EPS reached $1.38 (+33 %). Operating cash flow turned positive at $69 m (vs. $2 m), though free cash flow remained negative (-$56 m) after $125 m capex.

Balance sheet: Cash fell to $320 m from $721 m at FY24-end, largely due to $323 m of share repurchases (treasury stock now 5.0 m shares). Long-term debt was steady at $1.71 bn; leverage stays manageable (~2.3× net-debt/annualized EBITDA). Shareholders’ equity declined 6 % to $1.74 bn.

Operating highlights: Commercial jet engine revenue surged 27 % YoY to $448 m, now 39 % of total sales. Backlog stands at $3.7 bn (down from $4.1 bn), with ~70 % expected to convert within 12 months. Inventory rose 4 % to $1.41 bn reflecting volume ramp; inventory reserves increased to $80 m. ATI closed the sale of two small European units, recording a $3.7 m loss and $2 m cash proceeds.

No guidance was provided in the excerpt. Overall, ATI posted solid margin and EPS growth but used significant cash for buybacks amid a modest backlog decline.

ATI Inc. (NYSE: ATI)는 2025 회계연도 2분기, 13주 기간(2025년 6월 29일 종료)의 실적을 발표했습니다. 매출은 전년 대비 4% 증가한 11억 4천만 달러로, 9% 성장한 고성능 소재 및 부품(HPMC, 6억 900만 달러)이 정체된 고급 합금 및 솔루션(AA&S, 5억 3,200만 달러)을 상쇄했습니다. 매출총이익은 7% 증가한 2억 4,200만 달러였으며, 매출총이익률은 10bp 상승한 21.3%를 기록했습니다. 영업이익은 13% 증가한 1억 6,100만 달러(영업이익률 14.1%)를 기록했습니다.

연초 대비 매출은 6.9% 증가한 22억 9천만 달러이며, 희석 EPS는 33% 증가한 1.38달러를 기록했습니다. 영업활동 현금흐름은 2백만 달러에서 6,900만 달러로 전환되었으나, 1억 2,500만 달러의 자본적 지출 이후 잉여현금흐름은 여전히 마이너스(-5,600만 달러)였습니다.

재무상태: 현금은 FY24 말 7억 2,100만 달러에서 3억 2,000만 달러로 감소했으며, 이는 주로 3억 2,300만 달러 규모의 자사주 매입 때문입니다(자사주 보유량은 현재 500만 주). 장기부채는 17억 1천만 달러로 안정적이며, 레버리지는 연환산 EBITDA 대비 순부채 비율 약 2.3배로 관리 가능한 수준입니다. 자본총계는 6% 감소한 17억 4천만 달러입니다.

운영 하이라이트: 상업용 제트 엔진 매출은 전년 대비 27% 급증한 4억 4,800만 달러로, 전체 매출의 39%를 차지합니다. 수주잔고는 37억 달러(이전 41억 달러)이며, 약 70%가 12개월 이내 매출로 전환될 것으로 예상됩니다. 재고는 4% 증가한 14억 1,000만 달러로, 생산량 증가를 반영합니다; 재고 충당금은 8,000만 달러로 늘어났습니다. ATI는 두 개의 소규모 유럽 사업부 매각을 완료했으며, 370만 달러 손실과 200만 달러 현금 수익을 기록했습니다.

ATI Inc. (NYSE: ATI) meldete die Ergebnisse für das zweite Quartal des Geschäftsjahres 2025 für den 13-Wochen-Zeitraum bis zum 29. Juni 2025. Der Umsatz stieg im Jahresvergleich um 4 % auf 1,14 Mrd. USD, angetrieben durch ein Wachstum von 9 % im Bereich High Performance Materials & Components (HPMC, 609 Mio. USD), das die stagnierenden Advanced Alloys & Solutions (AA&S, 532 Mio. USD) ausglich. Der Bruttogewinn stieg um 7 % auf 242 Mio. USD; die Bruttomarge erhöhte sich um 10 Basispunkte auf 21,3 %. Das Betriebsergebnis stieg um 13 % auf 161 Mio. USD (Marge 14,1 %). Der auf ATI entfallende Nettogewinn sprang um 23 % auf 101 Mio. USD, was das verwässerte Ergebnis je Aktie (EPS) von 0,58 auf 0,70 USD anhob.

Der Umsatz im bisherigen Jahresverlauf wuchs um 6,9 % auf 2,29 Mrd. USD, das verwässerte EPS erreichte 1,38 USD (+33 %). Der operative Cashflow wurde mit 69 Mio. USD positiv (vorher 2 Mio. USD), während der freie Cashflow nach Investitionen von 125 Mio. USD weiterhin negativ blieb (-56 Mio. USD).

Bilanz: Die liquiden Mittel fielen von 721 Mio. USD zum Ende des Geschäftsjahres 2024 auf 320 Mio. USD, hauptsächlich bedingt durch Aktienrückkäufe in Höhe von 323 Mio. USD (eigene Aktien nun 5,0 Mio. Stück). Die langfristigen Schulden blieben mit 1,71 Mrd. USD stabil; die Verschuldung ist mit einem Verhältnis von ca. 2,3× Nettoverschuldung zum annualisierten EBITDA überschaubar. Das Eigenkapital der Aktionäre sank um 6 % auf 1,74 Mrd. USD.

Betriebliche Highlights: Die Erlöse aus kommerziellen Jet-Triebwerken stiegen um 27 % gegenüber dem Vorjahr auf 448 Mio. USD und machen nun 39 % des Gesamtumsatzes aus. Der Auftragsbestand liegt bei 3,7 Mrd. USD (vorher 4,1 Mrd.), wobei etwa 70 % innerhalb von 12 Monaten umgesetzt werden sollen. Die Lagerbestände stiegen um 4 % auf 1,41 Mrd. USD aufgrund erhöhter Volumina; die Lagerwertberichtigungen erhöhten sich auf 80 Mio. USD. ATI hat den Verkauf von zwei kleinen europäischen Einheiten abgeschlossen, dabei einen Verlust von 3,7 Mio. USD verbucht und 2 Mio. USD an Barmitteln eingenommen.

Im Auszug wurden keine Prognosen gegeben. Insgesamt verzeichnete ATI ein solides Wachstum bei Margen und EPS, nutzte jedoch erhebliche Mittel für Aktienrückkäufe bei leicht rückläufigem Auftragsbestand.

Positive
  • EPS up 21 % YoY to $0.70 on stronger mix and lower interest costs.
  • Operating margin expanded to 14.1 % (+110 bps YoY).
  • Operating cash flow turned positive at $69 m versus $2 m prior year.
  • Commercial jet engine revenue +27 %, demonstrating demand strength in core aerospace market.
Negative
  • Cash balance fell 56 % since year-end to $320 m, mainly from $323 m share buybacks.
  • Order backlog declined to $3.7 bn from $4.1 bn (-10 % YoY).
  • Free cash flow negative (-$56 m) after capex, despite positive operating cash.
  • Inventories and receivables rose, tying up additional $142 m working capital.

Insights

TL;DR: Solid earnings beat, but cash depleted by aggressive buybacks; backlog erosion tempers outlook.

Revenue and EPS beats stem from commercial aero strength and better cost controls. Operating margin >14 % is impressive for a materials supplier and reflects mix shift toward high-value HPMC products. Interest expense fell 11 %, adding to bottom-line leverage. However, cash halved in six months; $323 m repurchases exceed free cash generation, pushing net debt up and reducing balance-sheet flexibility. Backlog down 10 % YoY suggests decelerating order momentum, notably in Specialty Energy and Industrial markets, though 70 % within 12 months provides visibility. Overall impact is mixed: earnings momentum positive, liquidity trend negative.

TL;DR: Commercial jet engine sales accelerate, reinforcing ATI’s aero alloy leadership.

Jet-engine alloy revenue leapt 27 % YoY to $420 m in HPMC, reflecting sustained LEAP, GTF and GE9X build rates. ATI’s nickel-based and titanium alloy mix (48 % and 17 % of sales) supports margin expansion as spot nickel stabilizes. Airframe sales dipped 7 % as Airbus destocks; defense remains steady. Industrial markets were flat, showing discipline in capacity allocation. Strategic divestiture of small European ops removes distraction and modestly improves focus on aero core. From an industry view the quarter is bullish for ATI’s aero franchise.

USD (eigene Aktien nun 5,0 Mio. Stück). Die langfristigen Schulden blieben mit 1,71 Mrd. USD stabil; die Verschuldung ist mit einem Verhältnis von ca. 2,3× Nettoverschuldung zum annualisierten EBITDA überschaubar. Das Eigenkapital der Aktionäre sank um 6 % auf 1,74 Mrd. USD.

Betriebliche Highlights: Die Erlöse aus kommerziellen Jet-Triebwerken stiegen um 27 % gegenüber dem Vorjahr auf 448 Mio. USD und machen nun 39 % des Gesamtumsatzes aus. Der Auftragsbestand liegt bei 3,7 Mrd. USD (vorher 4,1 Mrd.), wobei etwa 70 % innerhalb von 12 Monaten umgesetzt werden sollen. Die Lagerbestände stiegen um 4 % auf 1,41 Mrd. USD aufgrund erhöhter Volumina; die Lagerwertberichtigungen erhöhten sich auf 80 Mio. USD. ATI hat den Verkauf von zwei kleinen europäischen Einheiten abgeschlossen, dabei einen Verlust von 3,7 Mio. USD verbucht und 2 Mio. USD an Barmitteln eingenommen.

Im Auszug wurden keine Prognosen gegeben. Insgesamt verzeichnete ATI ein solides Wachstum bei Margen und EPS, nutzte jedoch erhebliche Mittel für Aktienrückkäufe bei leicht rückläufigem Auftragsbestand.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Unaudited
Note 1. Accounting Policies
The interim consolidated financial statements include the accounts of ATI Inc. and its subsidiaries. Unless the context requires otherwise, “ATI” and “the Company” refer to ATI Inc. and its subsidiaries.
The Company follows a 4-4-5 or 5-4-4 fiscal calendar, whereby each fiscal quarter consists of thirteen weeks grouped into two four-week months and one five-week month, and its fiscal year ends on the Sunday closest to December 31. Unless otherwise stated, references to years and quarters in this Quarterly Report on Form 10-Q relate to fiscal years and quarters, rather than calendar years and quarters.
These unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information and with the instructions for Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and note disclosures required by U.S. generally accepted accounting principles for complete financial statements. In management’s opinion, all adjustments (which include only normal recurring adjustments) considered necessary for a fair presentation have been included. These unaudited consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s 2024 Annual Report on Form 10-K. The results of operations for these interim periods are not necessarily indicative of the operating results for any future period. The December 29, 2024 financial information has been derived from the Company’s audited consolidated financial statements.
New Accounting Pronouncements Adopted
In November 2023, the FASB issued new accounting guidance related to segment reporting disclosures. This guidance requires additional disclosures on an annual and interim basis of segment information, including significant segment expenses that are regularly provided to the chief operating decision maker (CODM) and the presentation and composition of other segment items, which is the difference between segment revenue less segment expenses and the measure of segment profit or loss. The guidance also requires that all current segment disclosures required on an annual basis be provided on an interim basis and requires disclosure of the title and position of the CODM and how the CODM uses the reported measure of segment profit or loss in assessing performance and allocating resources. This guidance does not change how an entity identifies its reportable segments. This new guidance, with the exception of interim disclosures, was effective for the Company in fiscal year 2024, and the Company adopted this new accounting guidance for annual disclosures effective January 1, 2024. The interim disclosures are effective for the Company in fiscal year 2025. The adoption of these changes did not have an impact on the Company’s consolidated financial statements other than disclosure requirements which are included in Note 11.
Pending Accounting Pronouncements
In December 2023, the FASB issued new accounting guidance related to income tax disclosures. This guidance requires an entity to disclose specific categories in its annual rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. This guidance also requires additional annual disclosures for income taxes paid and requires disaggregation of income before tax, between domestic and foreign, and income tax expense, between federal, state and foreign. This guidance also eliminates several current disclosure requirements related to: (1) the nature and estimate of the range of the reasonably possible change in the unrecognized tax benefits balance in the next 12 months, (2) making a statement that an estimate of the range cannot be made, and (3) disclosing the cumulative amount of each type of temporary difference when a deferred tax liability is not recognized because of the exceptions to comprehensive recognition of deferred taxes related to subsidiaries and corporate joint ventures. This new guidance includes annual disclosure requirements that will be effective for the Company for fiscal year 2025 and must be applied on a prospective basis with retrospective application permitted. Early adoption of this guidance is also permitted. The Company does not expect to early adopt this guidance and does not expect these changes to have an impact on the Company’s consolidated financial statements other than disclosure requirements.
In November 2024, the FASB issued new accounting guidance related to expense disaggregation disclosures. This guidance requires entities to disclose specified information about certain costs and expenses including (1) the amounts of purchases of inventory, employee compensation, depreciation, and intangible asset amortization, (2) include certain amounts that are already required to be disclosed under current generally accepted accounting principles in the same disclosure as the other disaggregation requirements, (3) a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively, and (4) the total amount of selling expenses and, in annual reporting periods, an entity’s definition of selling expenses. This new guidance for annual disclosures will be effective for the Company for fiscal year 2027 and for interim disclosures will be effective for the Company for fiscal year 2028. The guidance can be applied prospectively
6


or retrospectively and early adoption is permitted. The Company does not expect to early adopt this guidance and does not expect these changes to have an impact on the Company’s consolidated financial statements other than disclosure requirements.
Note 2. Revenue from Contracts with Customers

During the year-to-date period ended June 29, 2025, the Company de-recognized $0.5 million of restructuring reserves in connection with the sale of non-core operations in Birmingham, UK and Dusseldorf, Germany (see Note 5 for further explanation). The $3.1 million restructuring reserve balance at June 29, 2025 is recorded in other current liabilities on the consolidated balance sheet.
Supplier Financing
The Company participates in supplier financing programs with two financial institutions to offer its suppliers the option for access to payment in advance of an invoice due date. Under such programs, these financial institutions provide early payment to suppliers at their request for invoices that ATI has confirmed as valid at a predetermined discount rate commensurate with the creditworthiness of ATI. As of June 29, 2025 and December 29, 2024, the Company had $61.5 million and $34.8 million, respectively, reported in accounts payable on the consolidated balance sheets under such programs.
Sale of Receivables Program
During the fourth quarter of 2024, the Company entered into an accounts receivables purchase agreement (Receivables Purchase Agreement) with a third-party financial institution to periodically sell certain accounts receivables at a discount. These accounts receivable sales are accounted for as a sale of assets under ASC 860, Transfers and Servicing, as the Company’s continuing involvement is limited to servicing the accounts receivable, collecting the payments for the underlying accounts receivables and remitting such collections to the financial institution. The financial institution is responsible for any credit risk associated with the sold accounts receivable. The Company receives the purchase price, equal to the accounts receivable less the discount, at the time of the sale.
The Company sold $39.4 million and $68.2 million of its receivables under this program during the quarter and year-to-date periods ended June 29, 2025, respectively, resulting in de-recognition of the receivables from the Company’s consolidated balance sheet. The Company had no amounts collected on behalf of the financial institution under the Receivables Purchase Agreement at June 29, 2025. The losses associated with these transactions of $0.3 million and $0.5 million are reflected in the Company’s consolidated statement of operations for the quarter and year-to-date periods ended June 29, 2025, respectively, and are excluded from segment results. The cash received on these sales of accounts receivable during the year-to-date period ended June 29, 2025 is presented in changes in receivables within operating activities in the consolidated statement of cash flows.
Other Customer Receivable Sales
In the second quarter and year-to-date period ended June 29, 2025, the Company sold $91.5 million and $164.1 million, respectively, of certain customers’ accounts receivable through programs established by those customers with third-party financial institutions. In the second quarter and year-to-date period ended June 30, 2024, the Company sold $74.3 million and $142.3 million, respectively, of certain customers’ accounts receivable through programs established by those customers with third-party financial institutions. These customers have extended payment terms and provide the programs to enable suppliers to receive more timely payments. The Company has no continuing involvement with the receivables sold under these programs, including no servicing requirement. The proceeds from these transactions are presented in changes in receivables within operating activities in the consolidated statement of cash flows. The losses associated with these transactions of $1.3 million and $2.7 million for the quarter and year-to-date periods ended June 29, 2025, respectively, and $1.3 million and $2.9 million for the quarter and year-to-date periods ended June 30, 2024, respectively, are reflected in the Company’s consolidated statements of operations and are excluded from segment results.

Revolving Credit Facility

On June 13, 2025, the Company amended its Asset Based Lending (ABL) Credit Facility, which is collateralized by the accounts receivable and inventory of the Company’s operations. As amended, the ABL facility also provides the Company with the option of including certain machinery and equipment as additional collateral for purposes of determining availability under the facility. This amendment extended the ABL facility through June 2030. The amended ABL includes a $600 million revolving credit facility, a letter of credit sub-facility of up to $200 million, a $200 million term loan (Term Loan), and a swing loan facility of up to $60 million. Additionally, the amendment gives the Company the ability, through June 13, 2026 and as long as no default or event of default has occurred and is continuing, to borrow an additional term loan of up to $100 million in total, using one or two draws (the Delayed-Draw Term Loan). The Term Loan and Delayed-Draw Term Loan each bear interest at rate of 2.0% above the adjusted Secured Overnight Financing Rate (SOFR) and can be prepaid in increments of $25 million if certain minimum liquidity conditions are satisfied. In addition, the Company has the right to request an increase of up to $300 million in the maximum amount available under the revolving credit facility for the duration of the ABL.

The ABL, as amended, has applicable interest rates that are consistent with the previous facility, using SOFR plus an applicable SOFR adjustment. As amended, the applicable interest rate for revolving credit borrowings under the ABL facility includes interest rate spreads based on available borrowing capacity that range between 1.25% and 1.75% for SOFR-based borrowings and between 0.25% and 0.75% for base rate borrowings. The ABL facility contains a financial covenant whereby the Company must maintain a fixed charge coverage ratio of not less than 1.00:1.00 after an event of default has occurred and is continuing or if the undrawn availability under the ABL revolving credit portion of the facility is less than the greater of (i) 10% of the then applicable maximum loan amount under the revolving credit portion of the ABL and the outstanding Term Loan balance, or (ii) $60.0 million. The Company was in compliance with the fixed charge coverage ratio as of June 29, 2025. Additionally, the Company must demonstrate minimum liquidity specified by the facility during the 90-day period immediately preceding the stated maturity date of its 6.95% Debentures due 2025 issued by the Company’s wholly owned subsidiary, Allegheny Ludlum LLC, the 5.875% Senior Notes due 2027 and the 4.875% Notes due 2029. Costs associated with entering into the ABL amendment were $2.8 million, and are being amortized to interest expense over the extended term of the facility ending June 2030, along with $1.9 million of unamortized deferred costs previously recorded for the ABL. The ABL, as amended, also contains customary affirmative and negative covenants for credit facilities of this type, including limitations on the Company’s ability to incur additional indebtedness or liens or to enter into investments, mergers and acquisitions, dispositions of assets and transactions with affiliates, some of which are more restrictive at any time during the term of the ABL when the Company’s fixed charge coverage ratio is less than 1.00:1.00 and its undrawn availability under the revolving portion of the ABL is less than the greater of (a) $120 million or (b) 20% of the sum of the maximum loan amount under the revolving credit portion of the ABL and the outstanding Term Loan balance.

13


As of June 29, 2025, there were no outstanding borrowings under the revolving portion of the ABL facility, and $29.4 million was utilized to support the issuance of letters of credit. There were no revolving credit borrowings under the ABL facility during the year-to-date periods ended June 29, 2025 or June 30, 2024. The Company also has foreign credit facilities, primarily in China, that total $72 million based on June 29, 2025 foreign exchange rates, none of which was drawn as of June 29, 2025 or December 29, 2024.
Note 9. Derivative Financial Instruments and Hedging
As part of its risk management strategy, the Company, from time-to-time, utilizes derivative financial instruments to manage its exposure to changes in raw material prices, energy costs, foreign currencies, and interest rates. In accordance with applicable accounting standards, the Company accounts for most of these contracts as hedges.
The Company sometimes uses futures and swap contracts to manage exposure to changes in prices for forecasted purchases of raw materials, such as nickel, and natural gas. Under these contracts, which are generally accounted for as cash flow hedges, the price of the item being hedged is fixed at the time that the contract is entered into, and the Company is obligated to make or entitled to receive a payment equal to the net change between this fixed price and the market price at the date the contract matures.
The majority of ATI’s products are sold under contractual arrangements that include raw material surcharges and index mechanisms. However, as of June 29, 2025, the Company had entered into financial hedging arrangements, primarily at the request of its customers related to firm orders, for an aggregate notional amount of approximately 4 million pounds of nickel with hedge dates through 2027. The aggregate notional amount hedged is approximately 6% of a single year’s estimated nickel raw material purchase requirements. These derivative instruments are used to hedge the variability of a selling price that is based on the London Metal Exchange (LME) index for nickel, as well as to hedge the variability of the purchase cost of nickel based on this LME index. Any gain or loss associated with these hedging arrangements is included in sales or cost of sales, depending on whether the underlying risk being hedged is the variable selling price or the variable raw material cost, respectively.
At June 29, 2025, the outstanding financial derivatives used to hedge the Company’s exposure to energy cost volatility consisted of natural gas cost hedges. At June 29, 2025, the Company hedged approximately 65% of its forecasted domestic requirements for natural gas for the remainder of 2025 and approximately 35% for 2026.
While most of the Company’s direct export sales are transacted in U.S. dollars, it uses foreign currency exchange contracts, from time-to-time, to limit transactional exposure to changes in currency exchange rates for those transactions denominated in a non-U.S. currency. The Company sometimes purchases foreign currency forward contracts that permit it to sell specified amounts of foreign currencies it expects to receive from its export sales for pre-established U.S. dollar amounts at specified dates. In addition, the Company may also hedge forecasted capital expenditures and designate cash balances held in foreign currencies as hedges of forecasted foreign currency transactions. At June 29, 2025, the Company had no material outstanding foreign currency forward contracts.
The Company may enter into derivative interest rate contracts to maintain a reasonable balance between fixed- and floating-rate debt. There were no outstanding derivative interest rate contracts at June 29, 2025.
There are no credit risk-related contingent features in the Company’s derivative contracts, and the contracts contain no provisions under which the Company has posted, or would be required to post, collateral. The counterparties to the Company’s derivative contracts are substantial and creditworthy commercial banks that are recognized market makers. The Company controls its credit exposure by diversifying across multiple counterparties and by monitoring credit ratings and credit default swap spreads of its counterparties. The Company also enters into master netting agreements with counterparties when possible.

The fair values of the Company’s derivative financial instruments are presented below, representing the gross amounts recognized which are not offset by counterparty or by type of item hedged. All fair values for these derivatives were measured using Level 2 information as defined by the accounting standard hierarchy, which includes quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs derived principally from or corroborated by observable market data.

For derivative financial instruments that are designated as cash flow hedges, the gain or loss on the derivative is reported as a component of other comprehensive income (OCI) and reclassified into earnings in the same period or periods during which the hedged item affects earnings. For derivative financial instruments that are designated as fair value hedges, changes in the fair value of these derivatives are recognized in current period results. There were no outstanding fair value hedges as of June 29, 2025. The cash flow impact for all derivative financial instruments is reported in cash flows provided by operating activities on the consolidated statement of cash flows. The Company did not use net investment hedges for the periods presented. The effects of derivative instruments in the tables below are presented net of related income taxes, excluding any impacts of changes to income tax valuation allowances affecting results of operations or other comprehensive income, when applicable (see Note 15 for further explanation).
Assuming market prices remain constant with those at June 29, 2025, a pre-tax loss of $0.2 million is expected to be recognized over the next 12 months.

The gains (losses) reclassified from accumulated OCI into income on the interest rate swap are presented in interest expense in the same period as the interest expense on the Term Loan is recognized in earnings.
The disclosures of gains or losses presented above for nickel and other raw material contracts and foreign currency contracts do not consider the anticipated underlying transactions. Since these derivative contracts represent hedges, the net effect of any gain or loss on results of operations may be fully or partially offset.
The Company may also use derivative instruments that are not designated as hedges to protect the Company’s results from certain fluctuations in foreign exchange rates, as well as to offset a portion of the foreign currency gains and losses generated by the remeasurement of certain assets and liabilities denominated in non-functional currencies. Changes in the fair value of these foreign exchange contract derivatives not designated as hedging instruments are recorded in cost of sales or selling, general and administrative expenses on the consolidated statement of operations, and the Company recognized $1.1 million and $2.9 million of income, net, for settled foreign currency forward contracts that were not designated as hedges during the second quarter and year-to-date period ended June 29, 2025, respectively, and $0.5 million of expense during the second quarter and year-to-date period ended June 30, 2024, which offset foreign currency gains/losses in the relevant currency. We have no significant outstanding hedges that are not designated as of June 29, 2025.

In accordance with accounting standards, fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. Accounting standards established three levels of a fair value hierarchy that prioritize the inputs used to measure fair value. This hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows:
Level 1 – Quoted prices in active markets for identical assets or 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 or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.
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.

The availability of observable market data is monitored to assess the appropriate classification of financial instruments within the fair value hierarchy. Changes in economic conditions or model-based valuation techniques may require the transfer of financial instruments from one fair value level to another. In such instances, the transfer is reported at the beginning of the reporting period.

The following methods and assumptions were used by the Company in estimating the fair value of its financial instruments:
Cash and cash equivalents: Fair value was determined using Level 1 information.
Derivative financial instruments: Fair values for derivatives were measured using exchange-traded prices for the hedged items. The fair value was determined using Level 2 information, including consideration of counterparty risk and the Company’s credit risk.
Short-term and long-term debt: The fair values of the Company’s publicly traded debt were based on Level 1 information. The fair values of the other short-term and long-term debt were determined using Level 2 information.

Note 11. Business Segments
The Company operates under two business segments: High Performance Materials & Components (HPMC) and Advanced Alloys & Solutions (AA&S). ATI’s Chief Operating Decision Maker (CODM) is the Chief Executive Officer. Segment EBITDA, the Company’s segment operating measure, is used by the CODM to assess segment operating performance and to determine the allocation of resources. Segment EBITDA as a percentage of segment revenues is utilized to assess the profitability of each segment and whether the Company’s strategies are resulting in margin expansion and expected operating performance improvements. The measure of segment EBITDA excludes net interest expense, income taxes, depreciation and amortization, goodwill impairment charges, debt extinguishment charges, corporate expenses, closed operations and other income (expense), restructuring and other credits/charges, gains or losses on the sale of accounts receivables, strike related costs, long-lived asset impairments, pension remeasurement gains and losses, other postretirement/pension curtailment and settlement gains and losses, and gains or losses on sales of businesses. Management believes segment EBITDA, as defined, provides an appropriate measure of controllable operating results at the business segment level.

(1) The CODM is regularly provided with allocated corporate overhead and segment EBITDA, which is used to assess operating performance. Therefore, the significant expense categories and amounts align with the segment-level information that is regularly provided to the CODM. Intersegment expenses are included within the amounts shown.

(2) Other segment items for each reportable segment include: cost of sales, general and administrative expenses, and gain/loss on asset sales. General & administrative expenses consist of non-manufacturing payroll and benefits, office expenses, professional service and legal expenses, occupancy expenses including rent and lease expense, and travel expense.
Total international sales for the second quarter and year-to-date periods ended June 29, 2025 were $490.0 million and $990.6 million, respectively, and $456.8 million and $928.1 million for the second quarter and year-to-date period ended June 30, 2024, respectively. Of these amounts, sales by operations in the U.S. to customers in other countries for the second quarter and year-to-date period ended June 29, 2025 were $393.4 million and $808.3 million, respectively, and $355.3 million and $716.6 million for the second quarter and year-to-date period ended June 30, 2024, respectively.
Restructuring and other charges of $7.4 million for the quarter ended June 29, 2025 include $7.1 million of start-up and transaction related costs, which are included within cost of sales on the consolidated statements of operations and $1.6 million of losses on the sale of accounts receivable, which are included within selling and administrative expenses on the consolidated statements of operations. These charges were partially offset by credits of $1.3 million due to a reduction in severance-related reserves for a previous restructuring in the AA&S segment (see Note 7). Restructuring and other charges of $13.0 million for the year-to-date period ended June 29, 2025 include $11.1 million of start-up and transaction related costs, which are included within cost of sales on the consolidated statements of operations and $3.2 million of losses on the sale of accounts receivable, which are included within selling and administrative expenses on the consolidated statements of operations. These charges were partially offset by credits of $1.3 million due to a reduction in severance-related reserves for a previous restructuring in the AA&S segment (see Note 7).
Restructuring and other charges of $5.4 million for the quarter ended June 30, 2024 include $5.5 million of inventory write-downs related to the Company’s European restructuring and $1.8 million of start-up costs, both of which are included within cost of sales on the consolidated statements of operations. These charges were partially offset by credits of $1.9 million primarily due to a reduction in severance-related reserves (see Note 7). Restructuring and other charges of $8.5 million for the year-to-date period ended June 30, 2024 include $5.5 million of inventory write-downs related to the Company’s European
19


restructuring and $4.7 million of start-up costs, both of which are included within cost of sales on the consolidated statements of operations. These charges were partially offset by credits of $1.7 million primarily due to a reduction in severance-related reserves (see Note 7).

Note 12. Retirement Benefits
The Company has defined contribution retirement plans or defined benefit pension plans covering substantially all employees. Company contributions to defined contribution retirement plans are generally based on either a percentage of eligible pay or on hours worked. Benefits under the defined benefit pension plans are generally based on years of service and/or final average pay. The Company funds the U.S. pension plans in accordance with the Employee Retirement Income Security Act of 1974, as amended, and the Internal Revenue Code of 1986, as amended. The Company also sponsors several postretirement plans covering certain collectively bargained salaried and hourly employees. The plans provide health care and life insurance benefits for eligible retirees. In most retiree health care plans, Company contributions towards premiums are capped based on the cost as of a certain date, thereby creating a defined contribution. All defined benefit pension and retiree health care plans are closed to new entrants.
For the quarters ended June 29, 2025 and June 30, 2024, the components of pension and other postretirement benefit expense for the Company’s defined benefit plans included the following (in millions):

Note 13. Income Taxes
For the quarter and year-to-date period ended June 29, 2025, the Company’s effective tax rate was 22.0% and 19.7%, respectively, resulting in an income tax provision of $29.3 million and $50.3 million, respectively. For the quarter and year-to-date periods ended June 30, 2024, the Company’s effective tax rate was 22.8% and 21.5%, respectively, resulting in an income tax provision of $25.3 million and $42.2 million, respectively. The effective tax rate for the quarter ended June 29, 2025 included discrete tax expense of $0.6 million and the effective tax rate for the year-to-date period ended June 29, 2025 included discrete tax benefits of $4.5 million, primarily for share-based compensation. Excluding discrete tax impacts, the Company’s effective tax rate for the quarter and year-to-date period ended June 29, 2025 was 21.5%. The effective tax rate for the quarter and year-to-date period ended June 30, 2024 included discrete tax benefits of $1.6 million and $4.7 million, respectively. Excluding discrete tax benefits, the Company’s effective tax rate for the quarter and year-to-date period ended June 30, 2024 was 24.2% and 23.9%, respectively.
On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted, which includes permanent extensions of most expiring Tax Cuts and Jobs Act provisions and international tax changes. Pursuant to ASC 740, Income Taxes, the effects of changes in tax law are recognized in the period of enactment. The Company is still evaluating the potential impacts of the OBBBA; however, the Company does not anticipate it will have a material impact on the Company’s financial statements.

Common stock that would be issuable upon the assumed conversion of the 2025 Convertible Notes, prior to their redemption during the third quarter of 2024, and other option equivalents and contingently issuable shares are excluded from the computation of contingently issuable shares, and therefore, from the denominator for diluted earnings per share, if the effect of inclusion is anti-dilutive. There were no anti-dilutive shares for the quarters and year-to-date periods ended June 29, 2025 and June 30, 2024.
Periodically, the Company’s Board of Directors authorizes the repurchase of ATI common stock (the “Share Repurchase Program”), most recently authorizing the repurchase of up to $700 million, as announced in September 2024. Repurchases under these programs are made in the open market or in privately negotiated transactions, with the amount and timing of repurchases depending on market conditions and corporate needs. Open market repurchases are structured to occur within the pricing and volume requirements of SEC Rule 10b-18. In the quarter and year-to-date period ended June 29, 2025, ATI used $250.0 million and $320.0 million, respectively, to repurchase 3.2 million and 4.4 million, respectively, of its common stock under the Share Repurchase Program. At June 29, 2025, the Company has utilized $430 million of the $700 million currently authorized under the Share Repurchase Program. In the year-to-date period ended June 30, 2024, ATI used $150.0 million to repurchase 3.4 million shares of its common stock under the Share Repurchase Program.
The Company’s share repurchases are subject to a 1% excise tax due to the Inflation Reduction Act of 2022. Excise taxes incurred on share repurchases represent direct costs of the repurchase and are recorded as part of the cost basis of the shares within treasury stock. The cost of share repurchases for the quarter and year-to-date period ended June 29, 2025 of $252.6 million and $322.8 million, respectively, differs from the repurchases of common stock amounts in the consolidated statements of cash flows due to these excise taxes. The cost of share repurchases for the year-to-date period ended June 30, 2024 of $151.2 million differs from the repurchases of common stock amounts in the consolidated statements of cash flows due to these excise taxes.

Note 16. Commitments and Contingencies
The Company is subject to various domestic and international environmental laws and regulations that govern the discharge of pollutants and disposal of wastes, and which may require that it investigate and remediate the effects of the release or disposal of materials at sites associated with past and present operations. The Company could incur substantial cleanup costs, fines, and civil or criminal sanctions, third party property damage or personal injury claims as a result of violations or liabilities under these laws or noncompliance with environmental permits required at its facilities. The Company is currently involved in the investigation and remediation of a number of its current and former sites, as well as third party sites.
Environmental liabilities are recorded when the Company’s liability is probable and the costs are reasonably estimable. In many cases, however, the Company is not able to determine whether it is liable or, if liability is probable, to reasonably estimate the loss or range of loss. Estimates of the Company’s liability remain subject to additional uncertainties, including the nature and extent of site contamination, available remediation alternatives, the extent of corrective actions that may be required, and the number, participation, and financial condition of other potentially responsible parties (PRPs). The Company adjusts its accruals to reflect new information as appropriate. Future adjustments could have a material adverse effect on the Company’s consolidated results of operations in a given period, but the Company cannot reliably predict the amounts of such future adjustments.
At June 29, 2025, the Company’s reserves for environmental remediation obligations totaled approximately $15 million, of which $6 million was included in other current liabilities. The reserve includes estimated probable future costs of $3 million
25


for federal Superfund and comparable state-managed sites; $6 million for formerly owned or operated sites for which the Company has remediation or indemnification obligations; $5 million for owned or controlled sites at which Company operations have been or plan to be discontinued; and $1 million for sites utilized by the Company in its ongoing operations. The timing of expenditures depends on a number of factors that vary by site. The Company expects that it will expend present accruals over many years and that remediation of all sites with which it has been identified will be completed within thirty years. The Company continues to evaluate whether it may be able to recover a portion of past and future costs for environmental liabilities from third parties and to pursue such recoveries where appropriate.
Based on currently available information, it is reasonably possible that costs for recorded matters may exceed the Company’s recorded reserves by as much as $16 million. Future investigation or remediation activities may result in the discovery of additional hazardous materials or potentially higher levels of contamination than discovered during prior investigation and may impact costs associated with the success or lack thereof in remedial solutions. Therefore, future developments, administrative actions or liabilities relating to environmental matters could have a material adverse effect on the Company’s consolidated financial condition or results of operations and cash flows.
A number of other lawsuits, claims and proceedings have been or may be asserted against the Company relating to the conduct of its currently and formerly owned businesses, including those pertaining to product liability, environmental, health and safety matters and occupational disease (including as each relates to alleged asbestos exposure), as well as patent infringement, commercial, government contracting, construction, employment, employee and retiree benefits, taxes, environmental, and stockholder and corporate governance matters. While the outcome of litigation cannot be predicted with certainty, and some of these lawsuits, claims or proceedings may be determined adversely to the Company, management does not believe that the disposition of any such pending matters is likely to have a material adverse effect on the Company’s financial condition or liquidity, although the resolution in any reporting period of one or more of these matters could have a material adverse effect on the Company’s consolidated results of operations for that period.
The Company received employee retention tax credits under the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) during the fiscal year ended December 31, 2022. Due to the complex nature of the employee retention credit computations, the Company deferred recognition of a portion of the tax credits pending the completion of any potential audit or examination, or the expiration of the related statute of limitations. During the year-to-date period ended June 29, 2025, the Company recognized a benefit of approximately $7 million in cost of sales on the consolidated statement of operations due to the expiration of the statute of limitations for a portion of these credits. As of June 29, 2025, The Company has approximately $5 million of remaining deferred retention tax credits, of which the statute of limitations expires in 2028.
In August 2024, the Company received notice that it and certain of its affiliates are parties to two lawsuits captioned (1) William L. Schoen, Mary J. Nesbit, Robin L. Rosewicz, George E. Poole and James E. Swartz, Jr., individually and as representatives of a class of participants and beneficiaries of the Allegheny Technologies Incorporated Pension Plan v. ATI Inc., The Allegheny Technologies Incorporated Pension Plan Administrative Committee, State Street Global Advisors Trust Co., and John Does 1-5 (Case No. 2:24-cv-01109) and (2) John Souza and Karen Souza, individually and as representatives on behalf of a class of similarly situated persons v. ATI Inc. and State Street Global Advisors Trust Co. (Case No. 2:24-cv-01214), both of which are filed in federal district court for the Western District of Pennsylvania. These lawsuits, which were consolidated in late 2024, assert various claims associated with the Company’s October 2023 purchase of group annuity contracts to transfer a portion of its U.S. qualified defined benefit pension plan obligations to Athene Annuity and Life Company and Athene Annuity & Life Assurance of New York. The Company filed a Motion to Dismiss the consolidated claims on January 27, 2025, and briefing on the Motion has been completed. The Company disputes and intends to vigorously defend against these claims, but given the preliminary nature of these matters, cannot predict their outcome or estimate any range of reasonably possible loss at this time.

Item 2.Management’s Discussion and Analysis of Financial Condition and Results of Operations
Overview
ATI is a global manufacturer of technically advanced specialty materials and complex components. Our largest market is aerospace & defense, representing 66% of sales for the year-to-date period ended June 29, 2025, led by products for jet engines and airframes. Additionally, we have a strong presence in the specialty energy, medical and electronics markets. In aggregate, these markets represented 79% of our sales for the year-to-date period ended June 29, 2025. ATI is a market leader in manufacturing differentiated products that require our materials science capabilities and unique process technologies, including our new product development competence. Our capabilities range from cast/wrought and powder alloy development to final production of highly engineered finished components, including those used in latest generation jet engines and 3D-printed aerospace products.
ATI follows a 4-4-5 or 5-4-4 fiscal calendar, whereby each fiscal quarter consists of thirteen weeks grouped into two four-week months and one five-week month, and its fiscal year ends on the Sunday closest to December 31. Unless otherwise stated, references to years and quarters in this Quarterly Report on Form 10-Q relate to fiscal years and quarters, rather than calendar years and quarters.
Results of Operations
Sales
Second quarter 2025 sales increased 4% to $1.14 billion, compared to $1.10 billion of sales for the second quarter 2024, primarily due to increased demand for commercial jet engines, partially offset by a decline in sales for commercial airframes. In aggregate, ATI’s aerospace & defense market sales increased 11% to $762 million, or 67% of total sales in the second quarter 2025, compared to $684 million, or 62% of total sales in the second quarter 2024. The increase in aerospace & defense market sales was partially offset by sales declines of 37% to the medical market and 17% to the specialty energy market.
Sales for the year-to-date period ended June 29, 2025 increased 7% to $2.28 billion, compared to sales of $2.14 billion for the comparable 2024 period. The increase in sales was primarily due to a 17% increase in the aerospace & defense markets, driven by higher demand for commercial jet engines. The increase was partially offset by a 20% decline in sales to our other core markets, including declines of 33% and 14% in sales to the medical and specialty energy markets, respectively.

The increase in segment EBITDA, as a percentage of sales, was primarily due to higher sales and favorable pricing of nickel-based and specialty alloys. Results in the first half of 2025 and 2024 included benefits of $4.4 million and $3.5 million, respectively, from the recognition of previously deferred employee retention tax credits.
The Company’s investments to increase capacity and focus on continuous improvement are driving improvements to our work-flow processes and operations. HPMC results for 2025 reflected year-over-year improved operating leverage and pricing as we continued to experience increasing demand from the aerospace & defense market, especially for commercial jet engines. Although macro risks and uncertainty continue, we believe our capabilities, strong backlog and long-term agreements (“LTAs”) with aerospace market OEMs for our specialty materials, including powders, parts and components, position the HPMC segment for profitable growth for the next several years. ATI has prepared for the potential risks of tariffs for many years, and we have taken actions to minimize the impact of these tariffs in our contracts and supply chains. While we expect continued, near-term challenges, we believe the backlog of commercial aircraft production, increasing requirements for maintenance, repair, and operations, and the current OEM production forecasts support our long-term growth expectations in this end market.

Advanced Alloys & Solutions Segment

Second quarter 2025 sales of $531.6 million were relatively flat compared to the second quarter 2024, decreasing $1.7 million. Sales to the aerospace & defense market declined by $3.3 million, or 2%, as stronger demand for commercial jet engines was offset by a decline in sales of defense related applications. Sales to our other core markets also declined by $5.6 million, or 5%, primarily due to lower demand in the specialty energy and medical markets. These decreases were partially offset by an increase of $7.2 million, or 4%, in the industrial markets, primarily due to higher sales to the conventional energy market.

The margin decrease compared to the prior year was primarily due to sales mix changes, unfavorable manufacturing cost absorption and higher operating costs, which offset the benefit of higher sales volumes. In addition, results in the first half of 2025 include a benefit of $2.8 million from the recognition of previously deferred employee retention tax credits and a benefit of $2.6 million due to a customer recovery for previously reserved accounts receivable. The first half of 2024 includes a benefit of $5.1 million from the recognition of previously deferred employee retention tax credits.
While our margins for the AA&S segment declined on a year-over-year basis, we expect to see margin expansion in the second half of 2025 through improved sales mix and improved operating performance. We are also closely monitoring macro risks and uncertainty, and have taken actions to minimize the impact of tariffs in our contracts and supply chains.

Corporate Items
Corporate expenses for the second quarter of 2025 were $15.4 million, compared to $19.4 million for the second quarter 2024. For the year-to-date period ended June 29, 2025, corporate expenses were $32.8 million, compared to $36.5 million for the year-to-date period ended June 30, 2024. The decrease in corporate expenses for the quarter and year-to-date periods ended June 29, 2025 was primarily due to lower incentive compensation costs.
Closed operations and other income/expense for the second quarter 2025 was income of $2.4 million, compared to income of $0.7 million for the second quarter 2024. For the year-to-date period ended June 29, 2025, closed operations and other income/expense offset, compared to expense of $0.6 million for the year-to-date period ended June 30, 2024. Closed operations and other income/expense for the quarter and year-to-date periods ended June 29, 2025 benefited from foreign exchange gains and a favorable bankruptcy settlement related to an insurance claim.
Managed Working Capital
As part of managing the performance of our business, we focus on Managed working capital, a non-GAAP financial measure that we define as gross accounts receivable, short-term contract assets and gross inventories, excluding the effects of reserves for uncollectible accounts receivable and inventory valuation reserves, less accounts payable and short-term contract liabilities. We assess Managed working capital performance as a percentage of the prior three months annualized sales. Managed working capital is not intended to replace working capital or other GAAP financial measures or to be used as a measure of liquidity.

Management believes this non-GAAP financial measure focuses on the assets and liabilities most closely attributable to our core operations, allowing Management to quantify and evaluate the asset intensity of our business. Further, Management believes this non-GAAP financial measure provides investors with additional insights into the Company’s effectiveness in balancing the need to maintain appropriate asset levels to support sales growth and operations while deploying our cash effectively.
We employ several strategies to actively manage our Managed working capital, seeking to effectively balance the need to maintain appropriate levels of Managed working capital to support our growth and operations while deploying our cash efficiently. Our strategies include, but are not limited to, taking advantage of favorable customer and supplier payment terms, participating in supplier financing programs, accounts receivable factoring arrangements and other customer financing programs, managing the timing of purchases of raw materials, and leveling manufacturing process throughput and shipping to limit periodic increases in Managed working capital.
At June 29, 2025, Managed working capital increased as a percentage of annualized sales to 36.5% compared to 30.9% at December 29, 2024. The increase in Managed working capital as a percentage of annualized sales was primarily due to seasonal inventory builds and the timing of shipments, which impacts days sales outstanding, and vendor payments in the quarter. Days sales outstanding, which measures actual collection timing for accounts receivable, worsened by 14% as of June 29, 2025 compared to year end 2024. Gross inventory turns, which measures how many times we turn over our inventory relative to cost of sales in a year, worsened by 8% as of June 29, 2025 compared to year end 2024.

Liquidity and Financial Condition
On June 13, 2025, we amended our Asset Based Lending (ABL) Credit Facility, which is collateralized by the accounts receivable and inventory of our operations. As amended, the ABL facility also provides us with the option of including certain machinery and equipment as additional collateral for purposes of determining availability under the facility. This amendment extended the ABL facility through June 2030. The amended ABL includes a $600 million revolving credit facility, a letter of credit sub-facility of up to $200 million, a $200 million term loan (Term Loan), and a swing loan facility of up to $60 million. Additionally, the amendment gives the Company the ability, through June 13, 2026 and as long as no default or event of default has occurred and is continuing, to borrow an additional term loan of up to $100 million in total, using one or two draws (the Delayed-Draw Term Loan).
As of June 29, 2025, there were no outstanding borrowings under the revolving portion of the ABL facility, and $29.4 million was utilized to support the issuance of letters of credit. At June 29, 2025, we had $319.6 million of cash and cash equivalents, available additional liquidity under the ABL facility of approximately $570 million, and up to $100 million of availability under the Delayed-Draw Term Loan. Our next significant debt maturity is in the fourth quarter of this year and relates to the 6.95% Debentures due 2025 issued by our wholly owned subsidiary, Allegheny Ludlum LLC.
Periodically, our Board of Directors authorizes the repurchase of ATI common stock (the “Share Repurchase Program”), the most recent of which was $700 million that was announced in September 2024. Repurchases under these programs are made in the open market or in privately negotiated transactions, with the amount and timing of repurchases depending on market conditions and corporate needs. Open market repurchases are structured to occur within the pricing and volume requirements of SEC Rule 10b-18. In the quarter and year-to-date period ended June 29, 2025, ATI used $250 million and $320 million, respectively, to repurchase 3.2 million and 4.4 million, respectively, of its common stock under the Share Repurchase Program. At June 29, 2025, the Company has utilized $430 million of the $700 million currently authorized under the Share Repurchase Program. In the year-to-date period ended June 30, 2024, ATI used $150.0 million to repurchase 3.4 million shares of its common stock under the Share Repurchase Program.
We believe that internally generated funds, current cash on hand and available borrowings under the ABL facility will be adequate to meet our liquidity needs. In the event we decide to obtain additional financing, the cost and terms and conditions of such borrowings may be influenced by our credit rating. In addition, we regularly review our capital structure, various financing alternatives, and conditions in the debt and equity markets in order to opportunistically enhance our capital structure. As a result, we may seek to refinance or retire existing indebtedness, incur new or additional indebtedness or issue equity or equity-linked securities, in each case, depending on market and other conditions. We have no off-balance sheet arrangements as defined in Item 303(a)(4) of SEC Regulation S-K.
In managing our overall capital structure, we focus on the ratio of net debt to Adjusted EBITDA, which we use as a measure of our ability to repay our incurred debt. We define net debt as the total principal balance of our outstanding indebtedness excluding deferred financing costs, net of cash, at the balance sheet date. See above for our definition of Adjusted EBITDA, which is a non-GAAP measure and is not intended to represent, and should not be considered more meaningful than, or as an
37


alternative to, a measure of operating performance as determined in accordance with U.S. GAAP. Our ratio of net debt to Adjusted EBITDA (Adjusted EBITDA Leverage Ratio) measures net debt at the balance sheet date to Adjusted EBITDA as calculated on the trailing twelve-month period from this balance sheet date.
Our Total Debt to Adjusted EBITDA Leverage ratio improved in the second quarter of 2025 compared to year end 2024, while our Net Debt to Adjusted EBITDA Leverage ratio worsened in the second quarter of 2025 compared to year end 2024, largely due to a lower cash balance. The reconciliations of our Adjusted EBITDA Leverage Ratios to the balance sheet and income statement amounts as reported under U.S. GAAP are as follows:

Cash Flow
Cash provided by operations was $69.0 million in the year-to-date period ended June 29, 2025, compared to $2.3 million in the year-to-date period ended June 30, 2024. Both periods reflect higher accounts receivable and higher inventory balances due to increased operating levels as well as seasonal inventory builds. Working capital balances, and consequently cash from operations, can fluctuate throughout any operating period based upon the timing of receipts from customers and payments to vendors. Other significant first half 2025 and 2024 operating cash flow items included payment of the annual cash incentive compensation.
Cash used in investing activities was $119.2 million in the in the year-to-date period ended June 29, 2025, which included $125.4 million for capital expenditures. Cash used in investing activities was $117.1 million in the year-to-date period ended June 30, 2024, reflecting $126.0 million in capital expenditures primarily to support various growth projects in our aerospace & defense and other core markets. We expect to fund our capital expenditures with cash on hand and cash flow generated from our operations and, if needed, borrowings under the ABL facility.
Cash used in financing activities was $365.8 million in the year-to-date period ended June 29, 2025, which included $320.0 million to repurchase 4.4 million shares of ATI stock under our Share Repurchase Program. For the year-to-date period ended June 30, 2024, cash used in financing activities was $193.9 million, which included $150.0 million to repurchase 3.4 million shares of ATI stock under our Share Repurchase Program.
At June 29, 2025, cash and cash equivalents on hand totaled $319.6 million, a decrease of $401.6 million from year end 2024. Cash and cash equivalents held by our foreign subsidiaries was $146.0 million at June 29, 2025, of which $86.7 million was held by the STAL joint venture.

Reconciliation of Adjusted EBITDA to Net Income
ATI utilizes Adjusted EBITDA, which is a non-GAAP financial measure, to assist in assessing operating performance on a consistent basis across multiple reporting periods by removing the impact of special items, which can vary from period to period, that management does not believe are directly reflective of the Company’s core operations. The Company defines special items as significant non-recurring or non-operational charges or credits, including restructuring charges or credits, gains or losses on the sale of accounts receivable, strike related costs, goodwill and long-lived asset impairments, debt extinguishment charges, pension remeasurement gains and losses, other postretirement/pension curtailment and settlement gains and losses, and gains or losses on sales of businesses.
We define Adjusted EBITDA as net income, excluding net interest expense, income taxes, depreciation and amortization, and special items.
Management believes presenting this non-GAAP financial measure is useful to investors because it (1) provides investors with meaningful supplemental information regarding financial and operating performance by excluding certain items management believes do not directly impact the Company’s core operations, (2) permits investors to view performance using the same metrics that management uses to forecast, evaluate performance, and make operating and strategic decisions, and (3) provides additional information useful to investors on a period-to-period consistent basis that are commonly used to analyze companies’ operating performance. Management believes that consideration of Adjusted EBITDA, together with Net Income, and the corresponding reconciliation, provides investors with additional understanding of the Company’s performance and trends that would be absent such disclosures.
Non-GAAP financial measures should be viewed in addition to, and not superior to or as an alternative for, the Company’s reported results prepared in accordance with GAAP. The following table provides the reconciliation of net income attributable to ATI to the Adjusted EBITDA non-GAAP financial measures:

These charges were partially offset by credits of $1.3 million due to a reduction in severance-related reserves for a previous restructuring in the AA&S segment. Restructuring and other charges of $5.4 million for the second quarter of 2024 include $5.5 million of inventory write-downs related to our European restructuring and $1.8 million of start-up costs, both of which are included within cost of sales on the consolidated statements of operations. These charges were partially offset by credits of $1.9 million primarily due to a reduction in severance-related reserves. Restructuring and other charges of $13.0 million for the year-to-date period ended June 29, 2025 include $11.1 million of start-up and transaction related costs, which are included within cost of sales on the consolidated statements of operations, and $3.2 million for losses on sale of accounts receivable, which are included in selling and administrative expenses on the consolidated statement of operations. These charges were partially offset by credits of $1.3 million due to a reduction in severance-related reserves for a previous restructuring in the AA&S segment. Restructuring and other charges of $8.5 million for the year-to-date period ended June 30, 2024 include $5.5

These charges were partially offset by credits of 1.7 million primarily due to a reduction in severance-related reserves.
(b)Loss on sales of businesses of $3.7 million for the year-to-date period ended June 29, 2025 includes the sale of certain non-core European operations from the HPMC segment.
Critical Accounting Policies
Our critical accounting policies are discussed in Management’s Discussion and Analysis of Financial Condition and Results of Operations and in Note 1 to the Consolidated Financial Statements contained in our Annual Report on Form 10-K for the year ended December 29, 2024.
The preparation of the financial statements in accordance with U.S. generally accepted accounting principles requires us to make judgments, estimates and assumptions regarding uncertainties that affect the reported amounts of assets and liabilities. Significant areas of uncertainty that require judgments, estimates and assumptions include the accounting for derivatives, retirement plans, income taxes, environmental and other contingencies, as well as asset impairment, inventory valuation and collectability of accounts receivable. We use historical and other information that we consider to be relevant to make these judgments and estimates. However, actual results may differ from those estimates and assumptions that are used to prepare our financial statements.
Pending Accounting Pronouncements
See Note 1 of the Notes to Consolidated Financial Statements for information on new and pending accounting pronouncements.
Forward-Looking and Other Statements
From time to time, we have made and may continue to make “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Certain statements in this report relate to future events and expectations and, as such, constitute forward-looking statements. Forward-looking statements include those containing such words as “anticipates,” “believes,” “estimates,” “expects,” “would,” “should,” “will,” “will likely result,” “forecast,” “outlook,” “projects,” and similar expressions. Forward-looking statements are based on management’s current expectations and include known and unknown risks, uncertainties and other factors, many of which we are unable to predict or control, that may cause our actual results, performance or achievements to differ materially from those expressed or implied in the forward-looking statements. Important factors that could cause actual results to differ materially from those in the forward-looking statements include: (a) material adverse changes in economic or industry conditions generally, including global supply and demand conditions and prices for our specialty materials and changes in international trade duties and other aspects of international trade policy; (b) material adverse changes in the markets we serve; (c) our inability to achieve the level of cost savings, productivity improvements, synergies, growth or other benefits anticipated by management, from strategic investments and the integration of acquired businesses; (d) volatility in the price and availability of the raw materials that are critical to the manufacture of our products; (e) declines in the value of our defined benefit pension plan assets or unfavorable changes in laws or regulations that govern pension plan funding; (f) labor disputes or work stoppages; (g) equipment outages; (h) the risks of business and economic disruption associated with extraordinary events beyond our control, such as war, terrorism, international conflicts, public health issues, such as epidemics or pandemics, natural disasters and climate-related events that may arise in the future; and (i) other risk factors summarized in our Annual Report on Form 10-K for the year ended December 29, 2024, and in other reports filed with the Securities and Exchange Commission. We assume no duty to update our forward-looking statements.
Item 3.Quantitative and Qualitative Disclosures About Market Risk
As part of our risk management strategy, we utilize derivative financial instruments, from time to time, to hedge our exposure to changes in energy and raw material prices, foreign currencies, and interest rates. We monitor the third-party financial institutions which are our counterparties to these financial instruments daily and diversify our transactions among counterparties to minimize exposure to any one of these entities. Fair values for derivatives were measured using exchange-traded prices for the hedged items including consideration of counterparty risk and the Company’s credit risk. Our exposure to volatility in interest rates is presently not material, as nearly all of our debt is at fixed interest rates.
40


Volatility of Interest Rates. We may enter into derivative interest rate contracts to maintain a reasonable balance between fixed- and floating-rate debt. Any gain or loss associated with this hedging arrangement was included in interest expense. There are no outstanding derivative interest rate contracts at June 29, 2025.
Volatility of Energy Prices. Energy resource markets are subject to conditions that create uncertainty in the prices and availability of energy resources. The prices for and availability of electricity, natural gas, oil and other energy resources are subject to volatile market conditions. These market conditions often are affected by political and economic factors beyond our control. Increases in energy costs, or changes in costs relative to energy costs paid by competitors, have and may continue to adversely affect our profitability. To the extent that these uncertainties cause suppliers and customers to be more cost sensitive, increased energy prices may have an adverse effect on our results of operations and financial condition. We use approximately 6 to 8 million MMBtu’s of natural gas annually, depending upon business conditions, in the manufacture of our products. These purchases of natural gas expose us to the risk of higher gas prices. For example, a hypothetical $1.00 per MMBtu increase in the price of natural gas would result in increased annual energy costs of approximately $6 to $8 million. We use several approaches to minimize any material adverse effect on our results of operations or financial condition from volatile energy prices. These approaches include incorporating an energy surcharge on many of our products and using financial derivatives to reduce exposure to energy price volatility.
At June 29, 2025, the outstanding financial derivatives used to hedge our exposure to energy cost volatility consisted of natural gas hedges covering approximately 65% of our forecasted domestic requirements for natural gas for the remainder of 2025 and approximately 35% for 2026. At June 29, 2025, the net mark-to-market valuation of these outstanding natural gas hedges was an unrealized pre-tax gain of $2.9 million, comprised of $2.3 million in prepaid expenses and other current assets, $0.8 million in other long-term assets and $0.2 million in other current liabilities on the balance sheet. For the quarter ended June 29, 2025, natural gas hedging activity had an immaterial impact on cost of sales.
Volatility of Raw Material Prices. We use raw material surcharge and index mechanisms to offset the impact of increased raw material costs; however, competitive factors in the marketplace can limit our ability to institute such mechanisms, and there can be a delay between the increase in the price of raw materials and the realization of the benefit of such mechanisms. For example, in 2024, we used approximately 70 million pounds of nickel; therefore, a hypothetical change of $1.00 per pound in nickel prices would result in increased costs of approximately $70 million. While we enter into raw materials futures contracts from time-to-time to hedge exposure to price fluctuations, such as for nickel, we cannot be certain that our hedge position adequately reduces exposure. We believe that we have adequate controls to monitor these contracts, but we may not be able to accurately assess exposure to price volatility in the markets for critical raw materials.
The majority of our products are sold utilizing raw material surcharges and index mechanisms. However, as of June 29, 2025, we had entered into financial hedging arrangements, primarily at the request of our customers related to firm orders, for an aggregate notional amount of approximately 4 million pounds of nickel with hedge dates through 2027. The aggregate notional amount hedged is approximately 6% of a single year’s estimated nickel raw material purchase requirements. These derivative instruments are used to hedge the variability of a selling price that is based on the London Metal Exchange (LME) index for nickel, as well as to hedge the variability of the purchase cost of nickel based on this LME index. Any gain or loss associated with these hedging arrangements is included in sales or cost of sales, depending on whether the underlying risk being hedged was the variable selling price or the variable raw material cost, respectively. At June 29, 2025, the net mark-to-market valuation of our outstanding raw material hedges was an unrealized pre-tax loss of $2.3 million, comprised of $2.2 million in other current liabilities and $0.1 million in other long-term liabilities on the balance sheet.
Foreign Currency Risk. Foreign currency exchange contracts are used, from time-to-time, to limit transactional exposure to changes in currency exchange rates. We sometimes purchase foreign currency forward contracts that permit us to sell specified amounts of foreign currencies we expect to receive from our export sales for pre-established U.S. dollar amounts at specified dates. In addition, we may also hedge forecasted capital expenditures and designate cash balances held in foreign currencies as hedges of forecasted foreign currency transactions. At June 29, 2025, we had no material outstanding foreign currency forward contracts.
We may also use derivative instruments that are not designated as hedges to protect our results from certain fluctuations in foreign exchange rates, as well as to offset a portion of the foreign currency gains and losses generated by the remeasurement of certain assets and liabilities denominated in non-functional currencies. Changes in the fair value of these foreign exchange contract derivatives not designated as hedging instruments are recorded in cost of sales or selling, general and administrative expenses on the consolidated statement of operations, and we recognized $1.1 million and $2.9 million of income, net, for settled foreign currency forward contracts that were not designated as hedges during the second quarter and year-to-date period ended June 29, 2025, respectively, and $0.5 million of expense during the second quarter and year-to-date period ended June 30, 2024, which offset foreign currency gains/losses in the relevant currency. We have no significant outstanding hedges that are not designated as of June 29, 2025.

Item 4.Controls and Procedures
(a) Evaluation of Disclosure Controls and Procedures
Our Chief Executive Officer and Chief Financial Officer have evaluated the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) or Rule 15d-15(e) under the Securities Exchange Act of 1934, as amended) as of June 29, 2025, and they concluded that these disclosure controls and procedures are effective.

(b) Changes in Internal Controls
There was no change in our internal controls over financial reporting identified in connection with the evaluation of the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) or Rule 15d-15(e) under the Securities Exchange Act of 1934, as amended) as of June 29, 2025 conducted by our Chief Executive Officer and Chief Financial Officer, that occurred during the quarter ended June 29, 2025 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION
Item 1.Legal Proceedings
A number of lawsuits, claims and proceedings have been or may be asserted against the Company relating to the conduct of its currently or formerly owned businesses, including those pertaining to product liability, environmental, health and safety matters and occupational disease (including as each relates to alleged asbestos exposure), as well as patent infringement, commercial, government contracting, construction, employment, employee and retiree benefits, taxes, environmental, and stockholder and corporate governance matters. Certain of such lawsuits, claims and proceedings are described in our Annual Report on Form 10-K for the year ended December 29, 2024, and addressed in Note 16 to the unaudited interim financial statements included herein. While the outcome of litigation cannot be predicted with certainty, and some of these lawsuits, claims or proceedings may be determined adversely to the Company, management does not believe that the disposition of any such pending matters is likely to have a material adverse effect on the Company’s financial condition or liquidity, although the resolution in any reporting period of one or more of these matters could have a material adverse effect on the Company’s results of operations for that period.
Pension Annuitization Litigation. In August 2024, the Company received notice that it and certain of its affiliates are parties to two lawsuits captioned (1) William L. Schoen, Mary J. Nesbit, Robin L. Rosewicz, George E. Poole and James E. Swartz, Jr., individually and as representatives of a class of participants and beneficiaries of the Allegheny Technologies Incorporated Pension Plan v. ATI Inc., The Allegheny Technologies Incorporated Pension Plan Administrative Committee, State Street Global Advisors Trust Co., and John Does 1-5 (Case No. 2:24-cv-01109) and (2) John Souza and Karen Souza, individually and as representatives on behalf of a class of similarly situated persons v. ATI Inc. and State Street Global Advisors Trust Co. (Case No. 2:24-cv-01214), both of which are filed in federal district court for the Western District of Pennsylvania. These lawsuits, which were consolidated in late 2024, assert various claims associated with the Company’s October 2023 purchase of group annuity contracts to transfer a portion of its U.S. qualified defined benefit pension plan obligations to Athene Annuity and Life Company and Athene Annuity & Life Assurance of New York. The Company filed a Motion to Dismiss the consolidated claims on January 27, 2025, and briefing on the Motion has been completed. The Company disputes and intends to vigorously defend against these claims, but given the preliminary nature of these matters, cannot predict their outcome or estimate any range of reasonably possible loss at this time.
Richland Operations Local Air Permitting. In late 2024, Benton Clean Air Agency (“BCAA”) issued a Notice of Violation (“NOV”) to our subsidiary, International Hearth Melting, LLC d/b/a ATI Specialty Materials (“ATISM”) for failure to identify and quantify air pollutants in the original 1997 permit application for the Richland, Washington (“Richland”) electron beam furnace, which was purchased by ATISM in 1998, in alleged violation of certain provisions of the Washington Administrative Code (“WAC”). BCAA also issued an Order of Correction directing ATI to submit an application for installation of a pollution control device for the existing furnace and to install the approved pollution control device. On March 26, 2025, BCAA issued a second NOV to ATISM for failure to obtain an order of approval prior to construction of a second electron beam furnace, in alleged violation of the WAC. A permit approving the construction of the second furnace was issued March 17, 2025. On June 3, 2025, the Company submitted the application for installation of a pollution control device for the existing furnace. On July 21, 2025, the Company entered into a settlement agreement and agreed order with BCAA to resolve these matters, pursuant to which the Company agreed to pay an immaterial penalty.

Item 1A.Risk Factors
The following is an update to and should be read in conjunction with Item 1A. Risk Factors contained in the Company’s Annual Report on Form 10-K for the year ended December 29, 2024. In addition to the other information set forth in this report, you should carefully consider the factors discussed in Part I, “Item 1A. Risk Factors” in our Annual Report on Form 10- K for the year ended December 29, 2024, which could materially affect our business, financial condition or future results. The risks described in our Annual Report on Form 10-K are not the only risks facing our Company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.
Labor Matters. We have approximately 7,700 active employees, of which approximately 10% are located outside the United States. Approximately 35% of our workforce is covered by various collective bargaining agreements ("CBAs"), predominantly with the USW. At various times, our CBAs expire and are subject to renegotiation. Generally, CBAs that expire may be terminated after notice by the union. After termination, the union may authorize a strike. A labor dispute, which could lead to a strike, lockout, or other work stoppage by the employees covered by one or more of the collective bargaining agreements, could have a material adverse effect on production at one or more of our facilities and, depending upon the length of such dispute or work stoppage, on our operating results. There can be no assurance that we will succeed in concluding collective bargaining agreements to replace those that expire. On April 22, 2025, we reached agreements with the USW for new CBAs that cover nearly 1,000 USW represented full-time employees within our AA&S operations for a six-year term that extends through February 28, 2031.
Risks Associated with Current or Future Litigation and Claims. A number of lawsuits, claims and proceedings have been or may be asserted against us relating to the conduct of our currently and formerly owned businesses, including those pertaining to product liability, patent infringement, commercial disputes, government contracting, employment matters, employee and retiree benefits, taxes, environmental matters, health and safety and occupational disease, and stockholder and corporate governance matters. Due to the uncertainties of litigation, we can give no assurance that we will prevail on all claims made against us in the lawsuits that we currently face or that additional claims will not be made against us in the future. While the outcome of litigation cannot be predicted with certainty, and some of these lawsuits, claims or proceedings may be determined adversely to us, we do not believe that the disposition of any such pending matters is likely to have a material adverse effect on our financial condition or liquidity, although the resolution in any reporting period of one or more of these matters could have a material adverse effect on our results of operations for that period. Also, we can give no assurance that any other claims brought in the future will not have a material effect on our financial condition, liquidity or results of operations.
In August 2024, the Company received notice that it and certain of its affiliates are parties to two lawsuits, filed in federal district court for the Western District of Pennsylvania, that assert various claims associated with the Company’s October 2023 purchase of group annuity contracts to transfer a portion of its U.S. qualified defined benefit pension plan obligations to Athene Annuity and Life Company and Athene Annuity & Life Assurance of New York. These two lawsuits were consolidated in late 2024. In January 2025, we filed a Motion to Dismiss the consolidated claims, and briefing on the Motion has been completed. We intend to vigorously defend against these claims, but given the preliminary nature of these matters, cannot predict their outcome or estimate any range of reasonably possible loss at this time.
