Exhibit 99.1

NOTICE OF REDEMPTION TO THE HOLDERS OF THE

5.875% Notes due 2026

of Great Elm Capital Corp.

(CUSIP No. 390320 604)*

Redemption Date: May 27, 2026

NOTICE IS HEREBY GIVEN, pursuant to Section 1104 of the Indenture,

dated as of September 18, 2017 (the “Base Indenture”), by and between Great Elm Capital Corp., a Maryland corporation

(the “Company”), and Equiniti Trust Company, LLC (f/k/a American Stock Transfer & Trust Company, LLC) (the “Trustee”),

and Section 1.01(h) of the Fourth Supplemental Indenture, dated as of June 23, 2021 (the “Fourth Supplemental Indenture”

and, together with the Base Indenture, the “Indenture”), that the Company is electing to exercise its option to redeem,

in whole, the 5.875% Notes due 2026 (the “Notes”). Capitalized terms used but not defined herein shall have the meaning

ascribed to them in the Indenture.

The Company will redeem all of the issued and outstanding Notes on

May 27, 2026 (the “Redemption Date”). The redemption price for the Notes equals 100% of the principal amount

per Note being redeemed, or $25.00 per Note, plus the accrued and unpaid interest thereon, if any, through, but excluding, the Redemption

Date (the “Redemption Price”). The accrued interest per Note being redeemed that is payable on the Redemption Date

will be $0.228472.

On the Redemption Date, the Redemption Price will become due and payable

to the Holders of the Notes. Interest on the Notes being redeemed will cease to accrue on and after the Redemption Date. Unless the Company

defaults in paying the Redemption Price with respect to such Notes, the only remaining right of the Holders with respect to such Notes

will be to receive payment of the Redemption Price upon presentation and surrender of such Notes to the Trustee in its capacity as Paying

Agent.

Notes held in book-entry form will be redeemed and the Redemption Price

with respect to such Notes will be paid in accordance with the applicable procedures of The Depository Trust Company.

Payment of the Redemption Price to the Holders will be made upon presentation

and surrender of the Notes in the following manner:

If by Mail, Hand or Overnight Mail:

Equiniti Trust Company, LLC

1110 Centre Pointe Curve, Suite # 101, Mendota Heights, MN 55120

Onbase – Reorganization Dept.

Questions relating to this notice of redemption should be directed

to Equiniti Trust Company, LLC via telephone at 1–800-937-5449.

No representation is made as to the correctness or accuracy of the

CUSIP numbers listed in this notice or printed on the Notes.

Under U.S. federal income tax law, the Trustee or other withholding

agent may be required to withhold twenty-four percent (24%) of any gross payment to a holder who fails to provide a taxpayer identification

number and other required certifications. To avoid backup withholding, please complete a Form W-9 or an appropriate Form W-8, as applicable,

which should be furnished in connection with the presentment and surrender of the Notes called for redemption. Any amounts withheld under

the backup withholding rules will be allowed as a refund or a credit against a holder’s U.S. federal income tax liability provided

the required information is furnished to the Internal Revenue Service. Holders should consult their tax advisors regarding the withholding

and other tax consequences of the redemption.
