Other Events

On August 29, 2025, Great Elm Capital Corp. (the “Company”) caused (i) a notice (the “First Notice”) to be issued to the holders of its 8.75% Notes due 2028 (CUSIP No. 390320 802; NASDAQ: GECCZ) (the “Notes”) regarding the Company’s exercise of its option to redeem $30 million aggregate principal amount of the issued and outstanding Notes on September 30, 2025 (the “First Redemption Date”), pursuant to Section 1104 of the Indenture, dated as of September 18, 2017 (the “Base Indenture”), by and between the Company and Equiniti Trust Company, LLC (f/k/a American Stock Transfer & Trust Company, LLC), as trustee (the “Trustee”), and Section 1.01(h) of the Fifth Supplemental Indenture, dated as of August 16, 2023 (the “Fifth Supplemental Indenture”), by and between the Company and the Trustee and (ii) a notice (the “Second Notice”) to be issued to holders of the Notes regarding the Company’s exercise of its conditional option to redeem an additional $10 million aggregate principal amount of the issued and outstanding Notes on September 30, 2025 (the “Second Redemption Date”, together with the First Redemption Date, the “Redemption Dates”), pursuant to Section 1104 of the Base Indenture and Section 1.01(h) of the Fifth Supplemental Indenture. The Second Notice is subject to the condition precedent that the Company completes one or more financing transactions that generate net proceeds of at least $10 million (the “Financing Transactions”) prior to the Second Redemption Date. At the Company’s discretion, the Second Redemption Date may be delayed until such time (including more than 60 days after the date of the conditional notices to the holder of the Notes) as the Financing Transactions have been completed, or the redemption of the Notes to be redeemed pursuant to the Second Notice may not occur and the notices to the holders of such Notes may be rescinded if the Financing Transactions are not completed by the Second Redemption Date or by the date to which the Second Redemption Date is delayed. Pursuant to both the First Notice and the Second Notice, the Notes will be redeemed at 100% of their principal amount, plus accrued and unpaid interest thereon, if any, through, but excluding, the applicable Redemption Date. Interest is payable on the Notes quarterly on March 31, June 30, September 30 and December 31 of each year, and the next scheduled Interest Payment Date for the Notes is the Redemption Date. Accrued and unpaid interest on the Notes from June 30, 2025 to September 30, 2025 will be paid to the persons in whose name the Notes are registered at the close of business on September 15, 2025, which is the Regular Record Date for such interest payment. As such, the Company does not expect there to be any accrued and unpaid interest on the Notes as of September 30, 2025. If any holders purchase the Notes after September 15, 2025 and before September 30, 2025, they will not be entitled to receive any accrued and unpaid interest on the Notes unless the Notes are to be redeemed pursuant to the Second Notice and the Second Redemption Date is extended. If the Second Redemption Date is extended, the Company will pay accrued and unpaid interest thereon from September 30, 2025 through, but excluding, the Second Redemption Dated as so extended. Copies of the First Notice and the Second Notice are attached to this Current Report on Form 8-K as Exhibits 99.1 and 99.2 and are incorporated herein by reference.
