Credit facilities

In June 2022, the Company, and its wholly owned subsidiary, Quaker Houghton B.V., as borrowers, Bank of America, N.A., as administrative agent, U.S. dollar swing line lender and letter of credit issuer, Bank of America Europe Designated Active Company, as Euro Swing Line Lender, certain guarantors and other lenders entered into an amendment to its primary credit facility. The amended credit facility (the “Credit Facility”) established (A) a $150.0 million Euro equivalent senior secured term loan (the “Euro Term Loan”), (B) a $600.0 million senior secured term loan (the “U.S. Term Loan”), and (C) a $500.0 million senior secured revolving credit facility (the “Revolver”), each maturing in June 2027. The Company has the right to increase the amount of the Credit Facility by an aggregate amount not to exceed the greater of $300.0 million or 100% of Consolidated EBITDA, subject to certain conditions including the agreement to provide financing by any lender providing such increase.

Subsequent to the first quarter of 2026, in April 2026, the Company, and its wholly owned subsidiary, Quaker Houghton B.V., as borrowers, Bank of America, N.A., as administrative agent, U.S. dollar swing line lender and letter of credit issuer, Bank of America Europe Designated Active Company, as Euro Swing Line Lender, certain guarantors and other lenders entered into the fourth amendment to its primary credit facility, entered into in August 2019. The amended credit facility (the “Amended Credit Facility”) established (A) a $250.0 million Euro equivalent senior secured term loan (B) a $550.0 million senior secured term loan and (C) a $800.0 million senior secured revolving credit facility, each maturing in April 2031. The Company primarily used the proceeds from the Amended Credit Facility to repay in full all outstanding loans under the existing Credit Facility and to terminate the revolving credit commitments under the existing Credit Facility. The Company has the right to increase the amount of the Amended Credit Facility by an aggregate amount not to exceed (a) the greater of (i) $331.0 million and (ii) 100% of Consolidated EBITDA, subject to certain conditions including the agreement to provide financing by any lender providing such increase.

As of March 31, 2026, the Company was in compliance with all of the Credit Facility covenants. See Note 19, Debt, to Consolidated Financial Statements in the Company’s 2025 Form 10-K.

The weighted average variable interest rate incurred on the outstanding borrowings under the Credit Facility during the three months ended March 31, 2026 was approximately 4.8%. As of March 31, 2026, the weighted average variable interest rate on the outstanding borrowings under the Credit Facility was approximately 4.7%. As part of the Credit Facility, in addition to paying interest on outstanding principal, the Company is also required to pay an annual commitment fee ranging from 0.150% to 0.275% related to unutilized commitments under the Revolver, depending on the Company’s consolidated net leverage ratio. As of March 31, 2026, the Company had unused capacity under the Revolver of approximately $255 million, which is net of bank letters of credit of approximately $2 million.

In order to manage the Company’s exposure to variable interest rate risk associated with the Credit Facility, in the first quarter of 2023, the Company entered into $300.0 million notional amounts of three-year interest rate swaps to convert a portion of the Company’s variable rate borrowings to an average fixed rate of 3.64% plus an applicable margin as provided in the Credit Facility based on the Company’s consolidated net leverage ratio. In March 2026, the Company’s interest rate swap contracts expired. In April 2026, the Company entered into $400.0 million notional amounts of four-year interest rate swaps, converting a portion of the Company’s variable rate borrowings into an average fixed rate of 3.58% plus the applicable margin. See Note 17, Hedging Activities, for more information.

The Company capitalized third-party and credit debt issuance costs attributed to the Euro Term Loan, U.S. Term Loan and Revolver during the second quarter of 2022. Capitalized costs attributed to the Euro Term Loan and U.S. Term Loan are recorded as a direct offset to Long-term debt on the Condensed Consolidated Balance Sheets. Capitalized costs attributed to the Revolver are recorded within Other assets on the Condensed Consolidated Balance Sheets. These capitalized costs are amortized into Interest expense over the five-year term of the Credit Facility. As of March 31, 2026 and December 31, 2025, the Company had $0.5 million and $0.7 million, respectively, of debt issuance costs recorded as a reduction of Long-term debt and $1.2 million and $1.4 million, respectively, of debt issuance costs recorded within Other assets.

Industrial development bonds

As of March 31, 2026 and December 31, 2025, the Company had fixed rate, industrial development authority bonds totaling $10.0 million in principal amount due in 2028. These bonds have similar covenants to the Credit Facility noted above.

Bank lines of credit and other debt obligations

The Company has certain unsecured bank lines of credit and discounting facilities in certain foreign subsidiaries, which are not collateralized. The Company’s other debt obligations primarily consist of certain domestic and foreign low interest rate or interest-free municipality-related loans, local credit facilities of certain foreign subsidiaries, and finance lease obligations. Total unused capacity under these arrangements as of March 31, 2026 was approximately $58 million.

In addition to the bank letters of credit described in the “Credit facilities” subsection above, the Company maintains certain financial and other guarantees as off-balance sheet arrangements. Collectively, the total bank letters of credit and guarantees outstanding as of March 31, 2026 were approximately $7 million.
