7. | Long-Term Debt
On March 6, 2024, Midstream entered into the Sixth Amendment to Credit Agreement and related Promissory Notes on the non-revolving credit facility. The Sixth Amendment revised the interest rate from Term SOFR plus 2.00% to Term SOFR plus 2.00% subject to adjustment to Term SOFR plus 1.75% and Term SOFR plus 1.55% upon meeting certain milestones. The Sixth Amendment also consolidated the Promissory Notes to one Promissory Note with one lender, increased the available non-revolving credit facility to $25 million, and extended the maturity date to December 31, 2025. All other terms and requirements remained unchanged. On May 2, 2024, Midstream established a new $9 million revolving credit facility. The interest rate on the borrowings under the facility is Daily Simple SOFR plus 2.215%; the arrangement included a 0.40% upfront fee and 0.125% unused line fee. The facility matures on May 2, 2026. On May 29, 2024, Midstream paid in full the $9 million note payable that was set to mature June 1, 2024 with proceeds from the new credit facility. On March 6, 2024, Midstream amended and restated its $8 million Term Note. The amendment suspended quarterly principal payments beginning April 1, 2024 through January 1, 2025. Principal payments began again on April 1, 2025. All other terms and requirements of the Term Note were retained. The interest rate swap related to the $8 million Term Note was not amended on March 6, 2024. Long-term debt consists of the following:

Debt issuance costs are amortized over the life of the related debt. As of June 30, 2025 and September 30, 2024, the Company also had an unamortized loss on the early retirement of debt of $1,056,231 and $1,141,872, respectively, which has been deferred as a regulatory asset and is being amortized over a 20-year period. All debt agreements set forth certain representations, warranties and covenants to which the Company is subject, including financial covenants that limit consolidated long-term indebtedness to not more than 65% of total capitalization. All of the debt agreements provide for Priority Indebtedness (defined in the debt agreements) to not exceed 15% of consolidated total assets. The $15 million and $10 million notes, as well as the line-of-credit, have an interest coverage ratio requirement of not less than 1.5 to 1, which excludes the effect of the non-cash impairments on the LLC investments up to the total investment as of December 31, 2021, as revised by the Seventh Amendment to the Credit Agreement. The $9 million revolving line of credit facility also has an interest coverage ratio requirement of not less than 1.5 to 1. The Company was in compliance with all debt covenants as of June 30, 2025 and September 30, 2024. Subsequent to the end of the quarter, the Company entered into a firm letter of commitment with two banks that will refinance Midstream-related debt totaling $53.6 million. The note will have a seven-year term and an interest rate of SOFR plus 1.55%. In addition to interest, Midstream will repay principal based on a schedule aligned with the shipper contracts at MVP which will expire in June 2044. The note is guaranteed by RGC Resources, Inc., and there is a 30 basis point origination fee. Covenants are similar to those that exist on Midstream's outstanding debt. As a result of this firm commitment letter, the Company has reflected only $2.5 million of long-term debt as current on the balance sheet as of June 30, 2025 as it now has the intent and ability to refinance the existing maturities. The Company expects to finalize the arrangement in the fourth quarter.
