Item 1.01 Entry into a Material Definitive Agreement.

On June 25, 2025, Ampco-Pittsburgh Corporation (the “Corporation”), as guarantor, and certain of its subsidiaries effected the transactions set forth in that certain Second Amended and Restated Revolving Credit, Term Loan and Security Agreement (the “Credit Agreement”). Borrowers to the Credit Agreement include Air & Liquid Systems Corporation, Union Electric Steel Corporation, Alloys Unlimited and Processing, LLC, Akers National Roll Company, Åkers AB, Åkers Sweden AB and Union Electric Steel UK Limited (collectively, the “Borrowers”).

The Credit Agreement provides for a $100,000,000 senior secured asset-based revolving credit facility (the “Revolving Facility”), which can be increased up to $125,000,000 at the option of the Corporation and with the approval of the lenders. The Revolving Facility includes sublimits for letters of credit not to exceed $40,000,000 and European borrowings not to exceed $30,000,000. Borrowings under the Revolving Facility will bear interest at the Secured Overnight Financing Rate (“SOFR”) plus an applicable margin ranging between 2.00% and 2.50%. The Credit Agreement contains customary affirmative and negative covenants and limitations, including, but not limited to, investments in certain subsidiaries, payment of dividends, incurrence of additional indebtedness and guaranties, and acquisitions and divestitures. In addition, the Corporation must maintain a certain level of excess availability or otherwise maintain a minimum Fixed Charge Coverage Ratio of not less than 1.05 to 1.00. Repayment of the loans provided under the Credit Agreement is secured by first lien security interests on all accounts receivable, inventory and equipment (other than certain fixed assets securing the Term Loans (as defined below)). The maturity date for the Revolving Facility is June 25, 2030 and, subject to other terms and conditions of the Credit Agreement, would become due on that date.

Under the Credit Agreement, the Borrowers may also borrow up to $13,500,000 pursuant to senior secured term loans (the “Term Loans”). On the date of closing, $13,500,000 was advanced as Term Loans to the Corporation which is payable in equal monthly installments of $160,714 commencing August 1, 2025 and continuing on the first day of each month thereafter through the maturity date followed by a $4,017,857 obligation of all unpaid principal, plus accrued and unpaid interest and all unpaid fees and expenses. Borrowings under the Term Loans will bear interest at SOFR plus an applicable margin ranging between 3.00% and 3.50%. The Term Loans are secured by certain fixed assets of the Corporation that previously secured the First Amended and Restated Revolving Credit and Security Agreement, as amended. The proceeds from the Term Loans immediately reduced the borrowings outstanding on the Revolving Facility.

The obligation of the Corporation to pay amounts outstanding under the Credit Agreement may be accelerated upon the occurrence of an “Event of Default,” as defined in the Credit Agreement. Such Events of Default include, among others, (1) the Corporation’s failure to pay when due any principal, interest, other fee, charge, amount, or liability owed under the Credit Agreement, (2) any representation or warranty of the Corporation in the Credit Agreement being incorrect or misleading in any material respect on the date when made, (3) the Corporation’s failure to perform, keep or observe any term, provision, condition, or covenant contained in the Credit Agreement, and (4) the Corporation or any of its affiliates commencing a voluntary case under any state or federal bankruptcy or receivership laws or being adjudicated bankrupt or insolvent.
