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 September 28, 2025 and December 29, 2024, the Company had $42.1 million and $34.8 million, respectively, reported in accounts payable on the consolidated balance sheets under such programs.

On September 19, 2025, ATI Specialty Materials, LLC (“Specialty Materials”) and its indirect wholly owned subsidiary, ATI Securitization LLC (“ATI Securitization”) entered into a three-year, $125.0 million Receivables Purchase and Financing Agreement (the “Receivables Facility”) with PNC Bank, National Association, as Administrative Agent, and certain Purchasers/Lenders party thereto. Under the Receivables Facility, Specialty Materials sells or contributes, on an ongoing basis, certain of its trade accounts receivable, together with related security and interests in the proceeds thereof, to its wholly owned

subsidiary, ATI Securitization Holdings LLC (ATI Holdings). ATI Holdings subsequently sells or contributes those receivable and related security and interests to ATI Securitization, its wholly owned subsidiary, which is a consolidated bankruptcy-remote special purpose entity created for the sole purpose of transacting under the Receivables Facility. ATI Securitization may borrow from, and/or sell receivables under the Receivables Facility at fair value and will secure its obligations with a pledge of undivided interests in such receivables, together with related security and interest in the proceeds thereof. In all instances, Specialty Materials retains the servicing of the accounts receivable transferred, which includes collection and administrative activities. ATI has agreed to guarantee the performance of Specialty Materials obligations under the Receivables Facility.

The maximum aggregate funding available under the Receivables Facility is $125.0 million at any one time, subject to the availability of eligible receivables and other customary factors and conditions as well as covenants as set forth in the Receivables Facility. Amounts outstanding under the Receivables Facility accrue interest at an adjusted SOFR plus the applicable margin. The Receivables Facility also requires the maintenance of a minimum utilization level equal to 50% of the facility amount.

ATI Securitization is a separate legal entity with its own creditors. In the event of a liquidation of ATI Securitization, its creditors would be entitled to be satisfied out of the assets of ATI Securitization prior to any assets or value becoming available to creditors or equity holders for other ATI entities. The assets of ATI Securitization, including any funds of ATI Securitization that may be commingled with funds of any of its affiliates for purposes of cash management and related efficiencies, are not available to pay creditors of ATI or any affiliate thereof, except to the extent collections of receivables are in excess of the amounts owed by ATI Securitization under the Receivables Facility.

Sales of accounts receivable under the Receivables Facility meet the sale criteria under ASC 860, Transfers and Servicing (“ASC 860”), and are derecognized from the consolidated balance sheet. Cash receipts, received at the time of the sale of receivables under the Receivables Facility, are classified as cash flow from operating activities in the consolidated statement of cash flows. As the Company retains the servicing rights of the receivables sold, the Company assessed the associated servicing liability under ASC 860 and determined that the liability is immaterial to the Company’s financial statements.

For the three and nine months ended September 28, 2025, ATI Securitization sold $80.0 million of accounts receivable in exchange for $80.0 million of cash. The Company recorded a $0.9 million charge associated with the sale of the accounts receivable within selling and administrative expenses on its consolidated statement of operations. As of September 28, 2025, $80.0 million of the sold accounts receivable remained outstanding, which represents our maximum potential exposure under the guarantee.

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 receivable 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 receivable 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 $26.0 million and $94.2 million of its receivables under this program during the quarter and year-to-date periods ended September 28, 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 September 28, 2025. The losses associated with these transactions of $0.2 million and $0.7 million are reflected in the Company’s consolidated statement of operations for the quarter and year-to-date periods ended September 28, 2025, respectively, and are excluded from segment results. The cash received on these sales of accounts receivable during the year-to-date period ended September 28, 2025 is presented in changes in receivables within operating activities in the consolidated statement of cash flows.

In the third quarter and year-to-date period ended September 28, 2025, the Company sold $107.0 million and $271.1 million, respectively, of certain customers’ accounts receivable through programs established by those customers with third-party financial institutions. In the third quarter and year-to-date period ended September 29, 2024, the Company sold $69.8 million and $212.1 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 as changes in receivables within operating activities in the consolidated statement of cash flows. The losses associated with these transactions of $1.4 million and $4.1 million for the quarter and year-to-date periods ended September 28, 2025, respectively, and $1.4 million and $4.3 million for the quarter and year-to-date periods ended September 29, 2024, respectively, are reflected in the Company’s consolidated statements of operations and are excluded from segment results.
