On June 3, 2025, Lord Abbett Private Credit Fund S, a Delaware statutory trust (the “Company”), entered into a revolving credit facility (the “Revolving Credit Facility”) pursuant to a Senior Secured Credit Agreement (the “Credit Agreement”), by and among the Company, as borrower, ING Capital LLC (“ING”), as administrative agent (in such capacity, the “Administrative Agent”), each of the lenders and issuing banks party thereto, and ING, as lead arranger, as sole book runner and as a syndication agent. Capitalized terms used and not otherwise defined herein shall have the meanings specified in the Credit Agreement. The Revolving Credit Facility provides for, among other things, borrowings in U.S. dollars or certain other permitted currencies in an initial aggregate amount of up to $100,000,000, subject to availability under the borrowing base, with an option for the Company to elect at one or more times, subject to certain conditions, to increase the maximum committed amount up to $500,000,000.

The revolving period during which the Company is permitted to borrow, repay and re-borrow advances will terminate on June 4, 2029 (the “Commitment Termination Date”). Any amounts borrowed under the Revolving Credit Facility will mature, and all accrued and unpaid interest thereunder will be due and payable, on June 3, 2030 (the “Maturity Date”). During the period from the Commitment Termination Date to the Maturity Date, the Company will be obligated to make mandatory prepayments under the Revolving Credit Facility out of the proceeds of certain asset sales and other recovery events and equity and debt issuances.

The Company may borrow amounts in U.S. dollars or certain other permitted currencies. Borrowings under the Revolving Credit Facility accrue interest at a rate per annum equal to the relevant rate plus an applicable margin of (a) with respect to any ABR Loan, (i) 0.875% per annum if the Gross Borrowing Base is less than 1.60x the Combined Debt Amount or (ii) 0.75% per annum if the Gross Borrowing Base is greater than or equal to 1.60x the Combined Debt Amount; (b) with respect to any Term Benchmark Loan, (i) 1.875% per annum if the Gross Borrowing Base is less than 1.60x the Combined Debt Amount or (ii) 1.75% per annum if the Gross Borrowing Base is greater than or equal to 1.60x the Combined Debt Amount, and (c) with respect to any RFR Loans, (i) 1.875% per annum if the Gross Borrowing Base is less than 1.60x the Combined Debt Amount or (ii) 1.75% per annum if the Gross Borrowing Base is greater than or equal to 1.60x the Combined Debt Amount. In addition, the Company will pay a non-usage fee of 0.375% on the average daily unused amount of the revolving commitments under the Revolving Credit Facility.

In connection with the Revolving Credit Facility, the Company has made certain representations and warranties and is required to comply with various covenants, reporting requirements and other customary requirements for similar facilities. In addition, the Company must maintain an asset coverage ratio of at least 150% at all times.

The Revolving Credit Facility contains events of default customary for similar financing transactions of this type. Upon the occurrence of an event of default, the Administrative Agent may terminate the commitments and declare the outstanding advances and all other obligations under the Revolving Credit Facility immediately due and payable. During the continuation of an event of default, the Company may be required to pay interest at a default rate.

The Company’s obligations to the lenders under the Revolving Credit Facility are secured by a first priority security interest in substantially all of the assets of the Company, including its portfolio of loans and debt securities.

The foregoing description of the Revolving Credit Facility does not purport to be complete and is qualified in its entirety by reference to the full text of the Credit Agreement attached hereto as Exhibit 10.1.

The information set forth under Item 1.01 of this current report on Form 8-K is hereby incorporated in this Item 2.03 by reference.
