ITEM 1.01.

ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

On September 5, 2025, RGC Midstream, LLC (“Midstream”), a wholly owned subsidiary of RGC Resources, Inc. (“Resources”), entered into a Credit Agreement ("Agreement") borrowing $53,600,000 with Atlantic Union Bank (“Atlantic Union”) and CoBank, ACB ("CoBank"). The Agreement bears an interest rate of one month Term SOFR plus 155 basis points with interest payable monthly. Midstream will repay principal based on a schedule aligned with the terms of the Mountain Valley Pipeline ("MVP") shipper agreements, which will expire in June 2044. Quarterly principal payments will be due each October, January, April and July. In connection with this Agreement, Resources executed a Guaranty in favor of Atlantic Union and CoBank guaranteeing timely payment and performance of obligations by Midstream. The loan matures on September 5, 2032.

The proceeds from this note were used to refinance all of Midstream's existing debt. Also, on September 5, 2025, Midstream executed two interest rate swap agreements totaling $35,600,000 with Atlantic Union and CoBank corresponding to the term and draw provisions of the Agreement, which effectively converts that portion of the variable rate note to a fixed rate instrument with an effective annual interest rate of 5.061%. The two existing interest rate swaps with Atlantic Union will remain in place, have been redesignated, and when combined with the new interest rate swap agreement, hedges a notional value of $53,600,000.

Additionally, on September 5, 2025, Midstream entered into a Loan Agreement for the MVP Southgate extension and MVP expansion that can be drawn to principal amounts of $1,850,000 and $3,650,000, respectively, (the "Notes") with Atlantic Union. The Notes bear an interest rate of Term SOFR plus 175 basis points, subject to reduction to Term SOFR plus 155 basis points upon operation of MVP Southgate and operation of the MVP expansion, respectively, and commencement of cash distributions from MVP with interest payable monthly commencing October 1, 2025. The loan matures on October 1, 2030, at which time the outstanding principal balance on each note is due.

Both the Credit Agreement and Loan Agreement referenced above contain certain origination and other fees, and carry the same financial covenants included in other debt agreements including the limitation of Consolidated Long Term Indebtedness to not more than 65% of Consolidated Total Capitalization, Priority Indebtedness, as defined in the Agreement, to not more than 15% of Consolidated Total Assets and Consolidated Interest Coverage Ratio to no less than 1.50 to 1.00.
