Revolving Credit Facility

On September 19, 2013, the Company entered into a senior secured revolving credit agreement (as amended, the “Revolving Credit Facility”) with various lenders. Truist Bank serves as administrative agent and Bank of America, N.A. serves as syndication agent under the Revolving Credit Facility. The Company has amended and restated the Revolving Credit Facility on numerous occasions between October 3, 2014 and January 14, 2026. See Note 12 “Subsequent Events.”

The aggregate committed borrowing amount under the Revolving Credit Facility is $1,695,000. The Revolving Credit Facility includes an uncommitted accordion feature that allows the Company, under certain circumstances, to increase the borrowing capacity of the Revolving Credit Facility to up to $2,542,500.

Borrowings denominated in USD, including amounts drawn in respect of letters of credit, bear interest (at the Company’s election) of either (i) Term SOFR plus a margin of either (x) 2.00%, (y) 1.875% (subject to maintenance of certain long-term corporate debt ratings) or (z) 1.75% (subject to certain gross borrowing base conditions), in each case, plus an additional 0.10% credit adjustment spread or (ii) an alternative base rate, which is the highest of (a) zero, (b) the highest of (i) the Prime Rate in effect on such day, (ii) the Federal Funds Effective Rate for such day plus 1/2 of 1.00% and (iii) the rate per annum equal to (x) the greater of (A) Term SOFR for an interest period of one (1) month and (B) zero plus (y) 1.00%, plus a margin of either (x) 1.00%, (y) 0.875% (subject to maintenance of certain long-term corporate debt ratings) or (z) 0.75% (subject to certain gross borrowing base conditions). Borrowings denominated in non-USD bear interest of the applicable term benchmark rate or the applicable risk-free rate (the “RFR rate”) plus a margin of either 2.00%, 1.875% or 1.75% (subject to the conditions applicable to borrowings denominated in USD that bear interest based on the applicable term benchmark rate or the applicable RFR rate), plus, (i) in the case of borrowings denominated in GBP only, an additional 0.1193% credit adjustment spread, (ii) in the case of borrowings denominated in CHF only, an additional 0.0031% and (iii) in the case of borrowings denominated in CAD only, an additional 0.29547% (one-month interest period) or an additional 0.32138% (three-month interest period) credit adjustment spread. Borrowings from certain lenders, which hold approximately 84% of total lending commitments (the "Extending Lenders"), bear interest at the applicable rates described above less 0.10%. With respect to borrowings denominated in USD, the Company may elect either Term SOFR, or an alternative base rate at the time of borrowing, and such borrowings may be converted from one benchmark to another at any time, subject to certain conditions. Interest is payable in arrears on the applicable interest payment date as specified therein. The Company pays a fee of 0.375% per annum on committed but undrawn amounts under the Revolving Credit Facility, payable quarterly in arrears. Any amounts borrowed under the Revolving Credit Facility with respect to the Extending Lenders, will mature, and all accrued and unpaid interest will be due and payable, on June 24, 2030. Any amounts borrowed under the Revolving Credit Facility, will mature, and all accrued and unpaid interest will be due and payable, with respect to certain remaining lenders, on May 5, 2027, and with respect to other remaining lenders, on October 18, 2028.

The Revolving Credit Facility may be guaranteed by certain of the Company’s domestic subsidiaries, including any that are formed or acquired by the Company in the future. Proceeds from borrowings may be used for general corporate purposes, including the funding of portfolio investments.

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 Company’s portfolio of investments and cash, with certain exceptions. The Revolving Credit Facility contains certain covenants, including: (i) maintaining a minimum stockholder’s equity, (ii) maintaining a minimum asset coverage ratio of at least 150%, (iii) maintaining a minimum asset coverage ratio of 200% with respect to the consolidated assets (with certain limitations on the contribution of equity in financing subsidiaries as specified therein) of the Company and its subsidiary guarantors to the secured debt of the Company and its subsidiary guarantors, and (iv) complying with restrictions on industry concentrations in the Company’s investment portfolio. As of March 31, 2026, the Company was in compliance with these covenants.

Costs of $38,116 were incurred in connection with obtaining and amending the Revolving Credit Facility, which have been recorded as deferred financing costs in the Consolidated Statements of Assets and Liabilities and are being amortized over the life of the Revolving Credit Facility using the straight-line method. As of March 31, 2026 and December 31, 2025, the unamortized deferred financing costs were $12,444 and $13,245.
