Item 2.03. Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

On September 23, 2020, Ares Capital Corporation (the “Company”) issued an additional $400 million aggregate principal amount of its 3.875% notes due 2026 (the “New 2026 Notes”) pursuant to a Purchase Agreement, dated September 16, 2020 (the “Purchase Agreement”), among the Company, Ares Capital Management LLC, Ares Operations LLC and BofA Securities, Inc., J.P. Morgan Securities LLC, SMBC Nikko Securities America, Inc. and Wells Fargo Securities, LLC, as representatives of the several underwriters named on Schedule A thereto. The New 2026 Notes were issued as additional notes under the Indenture, dated October 21, 2010 (the “Base Indenture”), between the Company and U.S. Bank National Association (the “Trustee”), as supplemented by the Twelfth Supplemental Indenture, dated July 15, 2020 (the “Twelfth Supplemental Indenture,” and together with the Base Indenture, the “Indenture”), pursuant to which, on July 15, 2020, the Company issued $750 million aggregate principal amount of its 3.875% notes due 2026 (the “Existing 2026 Notes”). The New 2026 Notes are being treated as a single series with the Existing 2026 Notes under the Indenture and have the same terms as the Existing 2026 Notes. The New 2026 Notes have the same CUSIP number and are fungible and rank equally with the Existing 2026 Notes.

The New 2026 Notes were issued at a premium of 101.446% of their principal amount, resulting in estimated net proceeds, after estimated offering expenses, of approximately $402.1 million. Aggregate estimated offering expenses in connection with the offering of the New 2026 Notes, including the underwriting discount of $2.4 million, were approximately $3.7 million. The Company expects to use the net proceeds of this offering to repay certain outstanding indebtedness under its debt facilities. The Company may reborrow under its debt facilities for general corporate purposes, which include investing in portfolio companies in accordance with its investment objective.

The New 2026 Notes will mature on January 15, 2026 and may be redeemed in whole or in part at the Company’s option at any time at the redemption prices set forth in the Twelfth Supplemental Indenture. The New 2026 Notes bear interest at a rate of 3.875% per year payable semiannually on January 15 and July 15 of each year, commencing on January 15, 2021. The New 2026 Notes are direct senior unsecured obligations of the Company.

The New 2026 Notes were offered and sold pursuant to the Registration Statement on Form N-2 (File No. 333- 248831), the preliminary prospectus supplement filed with the Securities and Exchange Commission (the “SEC”) on September 16, 2020 and the pricing term sheet filed with the SEC on September 16, 2020.

The foregoing description of the New 2026 Notes does not purport to be complete and is qualified in its entirety by reference to the full text of the Twelfth Supplemental Indenture and the accompanying Form of 3.875% Notes due 2026, filed as Exhibits 4.1 and 4.2, respectively, to the Company’s Current Report on Form 8-K filed with the SEC on July 15, 2020 and incorporated by reference herein.
