6, our 4.875% Notes due 2028, our 8.00% Notes due 2028 and our 7.875% Notes due 2030 (collectively, the “Existing Notes”)). Because the Notes will not be secured by any of our assets, they will be effectively subordinated to any future secured indebtedness of Gladstone Investment Corporation (or any indebtedness that is initially unsecured as to which we subsequently grant a security interest) to the extent of the value of the assets securing such indebtedness. The Notes will be structurally subordinated to all existing and future indebtedness and other obligations of any of our subsidiaries (including borrowings under our revolving credit facility with KeyBank National Association), since the Notes will be obligations exclusively of Gladstone Investment Corporation and not of any of our subsidiaries. The Notes will be senior in right of payment to our common stock and any future outstanding series of our preferred stock. None of our subsidiaries is a guarantor of the Notes and the Notes will not be required to be guaranteed by any subsidiary we may acquire or create in the future. We do not intend to list the Notes on any securities exchange or automated dealer quotation system. Investing in the Notes involves a high degree of risk, including the risk of leverage. Before buying any Notes, you should read the material risks described in the “ Supplementary Risk Factors ” section beginning on page S-9of this prospectus supplement and in the “ Risk Factors ” section beginning on page 5 of the accompanying prospectus and under similar headings in the other documents that we file from time to time with the Securities and Exchange Commission (the “SEC”), which are incorporated by reference into this prospectus supplement and the accompanying prospectus. THE NOTES ARE NOT DEPOSITS OR OTHER OBLIGATIONS OF A BANK AND ARE NOT INSURED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION OR ANY OTHER GOVERNMENT AGENCY. This prospectus supplement, the accompanying prospectus, any free writing prospectus, and the documents incorporated by reference in this prospectus supplement and the accompanying prospectus contain important information you should know before investing in the Notes, including information about risks. Please read these documents before you invest and retain them for future reference. Additional information about us, including our annual, quarterly and current reports, has been filed with the Securities and Exchange Commission (the “SEC”) and can be accessed free of charge at its website at www.sec.gov.
