NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

1. | Basis of Presentation

Resources is an energy services company primarily engaged in the sale and distribution of natural gas. The condensed consolidated financial statements include the accounts of Resources and its wholly owned subsidiaries: Roanoke Gas and Midstream.

In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments (consisting of only normal recurring accruals) necessary to fairly present Resources' financial position as of June 30, 2025, cash flows for the nine months ended June 30, 2025 and 2024, and the results of its operations, comprehensive income, and changes in stockholders' equity for the three and nine months ended June 30, 2025 and 2024. The results of operations for the three and nine months ended June 30, 2025 are not indicative of the results to be expected for the fiscal year ending September 30, 2025 as quarterly earnings are affected by the highly seasonal nature of the business and weather conditions generally result in greater earnings during the winter months.

The unaudited condensed consolidated financial statements and related notes are presented under the rules and regulations of the SEC. Pursuant to those rules, certain information and note disclosures normally included in the annual financial statements prepared in accordance with GAAP have been condensed or omitted. Although the Company believes that the disclosures are adequate, the unaudited condensed consolidated financial statements and the related notes should be read in conjunction with the financial statements and notes contained in the Company’s Form 10-K for the year ended September 30, 2024. The September 30, 2024 consolidated balance sheet was included in the Company’s audited financial statements included in Form 10-K.

In August 2025, the Company obtained a commitment letter to refinance $53.6 million of Midstream debt that was maturing in fiscal 2026. See Note 7 for a discussion of this transaction. These actions have resolved the uncertainty that gave rise to the conditions that were disclosed last quarter under ASU 2014-15.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

The Company’s significant accounting policies are described in Note 1 to the consolidated financial statements contained in the Company's Form 10-K for the year ended September 30, 2024.

Certain amounts previously disclosed have been reclassified to conform to current year presentations.

Recently Issued or Adopted Accounting Standards

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures. The new guidance is designed to provide users of financial statements with improved reportable segment disclosures, primarily through enhanced disclosures about significant segment expenses, other segment items and measures of segment profit or loss used by the chief operating decision maker (CODM). Additionally, the new guidance requires a public entity to provide in interim periods all disclosures about a reportable segment’s profit or loss and assets that are currently required annually, which the Company currently discloses on an interim basis. The new guidance is effective for the Company for fiscal year beginning October 1, 2024 and interim periods within fiscal year beginning October 1, 2025. The Company continues to refine its assessment of the impact of the new guidance on its financial statement disclosures, and expects the adoption of this standard will result in expanded disclosures within the segment reporting footnote, specifically regarding the information provided to the CODM and how the CODM uses the information in assessing the performance of each segment.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The new guidance requires that on an annual basis public business entities disclose specific categories in the rate reconciliation table and provide additional information for reconciling items that meet a quantitative threshold (items equal to or greater than 5 percent of the amount computed by multiplying pretax income or loss by the applicable statutory rate). The required disclosures will provide more granularity regarding the payment of income taxes to federal, state and foreign entities. The Company does not expect certain requirements of this ASU to have a significant impact to its current disclosures as all of its operations are domestic and reside in two states. Changes to the rate reconciliation table will result in additional disclosure. The new guidance is effective for the Company for annual periods beginning October 1, 2025.

In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income (Topic 220): Expense Disaggregation Disclosures. The new guidance requires public business entities to disclose certain additional detail about expenses including, among other items, purchases of inventory, employee compensation, depreciation and intangible asset amortization included within each income statement expense line items within continuing operations. The guidance also requires disclosure of the total amount of selling expenses and the Company’s definition of selling expenses. Such disclosures must be made on an annual and interim basis and integrated with existing disclosure requirements in a tabular format in the footnotes to the financial statements. Further, in January 2025, the FASB issued ASU 2025-01, Income Statement - Reporting Comprehensive Income (Topic 220): Expense Disaggregation Disclosures: Clarifying the Effective Date, which clarified the effective date of ASU 2024-03. The new guidance is effective for the Company for fiscal year beginning October 1, 2027 and interim periods within fiscal year beginning October 1, 2028. The Company is currently assessing the impacts of the new guidance on its financial statement disclosures.

Other accounting standards that have been issued by the FASB, SEC or other standard-setting bodies are not currently applicable to the Company or are not expected to have a material impact on the Company’s financial position, results of operations or cash flows.

2. | Revenue

The Company assesses new contracts and identifies related performance obligations for promises to transfer distinct goods or services to the customer. Revenue is recognized when performance obligations have been satisfied. In the case of Roanoke Gas, the Company contracts with its customers for the sale and/or delivery of natural gas.

Gas utility revenues

Substantially all of Roanoke Gas' revenues are derived from rates authorized by the SCC through its tariffs. Based on its evaluation, the Company has concluded that these tariff-based revenues fall within the scope of ASC 606, Revenue from Contracts with Customers. Tariff rates represent the transaction price. Performance obligations include the procurement and transportation of natural gas through the Company's distribution system to customers. The delivery of natural gas to customers results in the satisfaction of the Company’s respective performance obligations over time.

All customers are billed monthly based on consumption as measured by metered usage with payments due 20 days from the rendering of the bill. Revenue is recognized as bills are issued for natural gas that has been delivered or transported. In addition, the Company utilizes the practical expedient that allows an entity to recognize the invoiced amount as revenue, if that amount corresponds to the value received by the customer. Since customers are billed tariff rates, there is no variable consideration in the transaction price.

Unbilled revenue is included in residential and commercial revenues in the preceding table. Natural gas consumption is estimated for the period subsequent to the last billed date and up through the last day of the month. Estimated volumes and approved tariff rates are utilized to calculate unbilled revenue. The following month, the unbilled estimate is reversed, the actual usage is billed and a new unbilled estimate is calculated. The Company obtains metered usage for transportation and interruptible customers at the end of each month, thereby eliminating any unbilled consideration for these rate classes.

Table of Contents

RGC RESOURCES, INC. AND SUBSIDIARIES

Other revenues

Other revenues primarily consist of miscellaneous fees and charges, utility-related revenues not directly billed to utility customers and billings for non-utility activities. Customers are invoiced monthly based on services provided for these activities. The Company utilizes the practical expedient allowing revenue to be recognized based on invoiced amounts. The transaction price is based on a contractually predetermined rate schedule; therefore, the transaction price represents total value to the customer and no variable price consideration exists.

Alternative revenue program revenues

ARPs, which fall outside the scope of ASC 606, are SCC-approved mechanisms that allow for the adjustment of revenues for certain broad, external factors, or for additional billings if the entity achieves certain performance targets. The Company's ARPs include its WNA, which adjusts revenues for the effects of weather temperature variations as compared to the 30-year average; the SAVE Plan over/under collection mechanism, which adjusts revenues for the differences between SAVE Plan revenues billed to customers and the revenue earned, as calculated based on the timing and extent of infrastructure replacement completed during the period; and the RNG over/under collection mechanism, which adjusts revenues similar to the SAVE Plan, but is calculated based on the timing and costs associated with owning, operating and maintaining the RNG facility. These amounts are ultimately collected from, or returned to, customers through future rate changes as approved by the SCC.

Customer accounts receivable and liabilities

Accounts receivable, as reflected in the condensed consolidated balance sheets, includes both billed and unbilled customer revenues, as well as amounts that are not related to customers. The asset and liability balances associated with customers are provided below:

|  | Current Assets |  |  | Current Liabilities |
|  | Trade accounts receivable(1) |  |  | Unbilled revenue(1) |  |  | Customer credit balances |  |  | Customer deposits |
Balance at September 30, 2024 |  | $ | 3,080,140 |  |  | $ | 1,294,798 |  |  | $ | 1,915,859 |  |  | $ | 1,488,113 |

Increase (decrease) |  | $ | 1,643,356 |  |  | $ | 46,640 |  |  | $ | (901,949 | ) |  | $ | 4,437 |

(1) Included in accounts receivable in the condensed consolidated balance sheet. Amounts shown net of reserve for credit losses.

The Company did not incur any significant costs to obtain contracts during the period. Certain customers elect to pay even amounts monthly, giving rise to assets and liabilities presented in the table above. All amounts clear annually.

3. | Segment Information

Operating segments are defined as components of an enterprise for which separate financial information is available and evaluated regularly by the Company's executive management in deciding how to allocate resources and assess performance. The Company uses operating income and equity in earnings to assess segment performance.

Intersegment transactions are recorded at cost.

The reportable segments disclosed herein are defined as follows:

Gas Utility - The natural gas segment of the Company generates revenue from its tariff rates and other regulatory mechanisms through which it provides the sale and distribution of natural gas to its residential, commercial and industrial customers.

Investment in Affiliates - The investment in affiliates segment reflects the income generated through the activities of the Company's investment in the LLC.

4. | Rates and Regulatory Matters

The SCC exercises regulatory authority over the natural gas operations of Roanoke Gas. Such regulation encompasses terms, conditions and rates to be charged to customers for natural gas service, safety standards, service extension and depreciation.

In response to continued inflationary pressures, Roanoke Gas filed a general rate application with the SCC on February 2, 2024 seeking to increase its annual non-gas base rates by $4.33 million and its permitted return on equity from 9.44% to 10.35% reflecting its higher cost of capital, including higher interest expense. The SCC permitted the Company to implement its new rates on an interim basis for customer billings on or after July 1, 2024, subject to refund. On October 16, 2024, the Company reached a settlement with the SCC staff on all outstanding issues in the case. Under the terms of the settlement, the Company agreed to an annual incremental revenue requirement increase of $4.08 million based on a return on equity of 9.90%. On April 10, 2025, the SCC issued a final order approving the settlement agreement in its entirety. Refunds for the difference in amounts that were billed based on interim and settlement rates, which had previously been accrued, were made to customers in May 2025.

On May 30, 2025, Roanoke Gas filed for approval of an updated RNG Rider to become effective October 1, 2025. The revenue requirement associated with the proposed RNG Rider is $1.66 million, offset by the sale of environmental credits, the recovery of under recovery of costs during the prior fiscal year and the over crediting of customers for RIN sales. The Company expects a decision from the SCC in September 2025.

On June 30, 2025, Roanoke Gas filed for approval of an updated annual SAVE Rider rate to become effective October 1, 2025. The proposed SAVE Rider is based on an estimated $10.33 million of SAVE eligible investment during fiscal 2026 and a revenue requirement of $2.64 million, inclusive of the adjustment for under-recovered costs incurred during the prior year. The updated SAVE Rider also reflects the cost of capital approved by the Commission in its April 10, 2025 Rate Case Final Order. The Company expects a decision from the SCC in September 2025.

5. | Other Investments

Midstream owns a less than 1% equity investment in the LLC that owns and operates the MVP. The Company accounts for its interest in the LLC under the equity method of accounting given the LLC maintains specific ownership accounts for each investor, and also considering the Company's rights under the LLC management agreement. The Company has been using the equity method since the inception of its investment in fiscal 2016. Following receipt of authorization from the FERC, the MVP entered commercial operation on June 14, 2024 and became available for interruptible or short-term firm transportation service. On July 1, 2024, the MVP commenced long-term firm capacity obligations. Midstream is also a less than 1% investor, accounted for under the cost method, in Southgate, which is in the design and permitting phase. Completion of the Southgate project is targeted for 2028.

AFUDC attributable to MVP construction was recognized during the prior year and is included in the equity in earnings of unconsolidated affiliate in the tables below. AFUDC ceased in June 2024 when MVP went into commercial operation.

The Company participates in the earnings of the LLC proportionate to its level of investment, favorably adjusted for a basis difference between the Company's capital account and its carrying value that arose when the Company recorded an other-than-temporary impairment of its investment in 2022. This basis difference amortization is a favorable non-cash adjustment to income over the book life of the MVP, which is 40 years. The Company's share of earnings from the LLC and the basis difference amortization are presented under equity in earnings of unconsolidated affiliate on the condensed consolidated statements of income. The Company received three quarterly cash distributions totaling approximately $2.7 million from the LLC during the first nine months of fiscal 2025 and expects future quarterly distributions to be of a similar magnitude to those received to date.

Midstream assesses the value of its investment in the LLC on at least a quarterly basis, and no impairment indicators were identified in fiscal 2025 or 2024.

Investment balances of MVP and Southgate, as of June 30, 2025 and September 30, 2024, are reflected in the table below:

6. | Line of Credit

The Company had been operating with an unsecured Revolving Note in the principal amount of $25 million that it renewed annually each March. On March 31, 2025, Roanoke Gas amended its Revolving Note to increase the principal amount to $30 million and extend the maturity date to March 31, 2027. The Revolving Note's variable interest rate is based upon Term SOFR plus 1.25% and provides for multiple tier borrowing limits to accommodate seasonal borrowing demands. Other key terms and requirements of the Revolving Note were retained. The Company's total available borrowing limits during the term of the Revolving Note range from $20 million to $30 million. As of June 30, 2025, the Company had an outstanding balance of $4,991,528 under the Revolving Note.

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.

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.

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.

8. | Derivatives and Hedging

The Company’s hedging and derivative policy allows management to enter into derivatives for the purpose of managing the commodity and financial market risks of its business operations, including the price of natural gas and the cost of borrowed funds. This policy specifically prohibits the use of derivatives for speculative purposes.

The Company has four interest rate swaps associated with certain of its variable rate debt as of June 30, 2025. Roanoke Gas has two variable-rate term notes in the amounts of $15 million and $10 million, with corresponding swap agreements to effectively convert the variable interest rates into fixed rates of 2.00% and 2.49%, respectively. Midstream has two swap agreements corresponding to the variable-rate term notes with original principal amounts of $14 million and $8 million. The swap agreement pertaining to the $14 million note effectively converts the variable interest rate into a fixed rate of 3.24%. The swap agreement pertaining to the $8 million note remains in place and was concurrently re-designated to hedge an applicable portion of the note, taking into account the temporary suspension of amortization described in Note 7, and converts that portion of the note to a fixed rate of 2.443%. The swaps qualify as cash flow hedges with changes in fair value reported in other comprehensive income. No portion of the swaps were deemed ineffective during the periods presented.

The fair value of the current and non-current portions of the interest rate swaps are reflected in the condensed consolidated balance sheets under the caption interest rate swaps. The table in Note 11 reflects the effect on income and other comprehensive income of the Company's cash flow hedges.

9. | Fair Value Measurements

ASC 820, Fair Value Measurements and Disclosures, established a fair value hierarchy that prioritizes each input to the valuation method used to measure fair value of financial and nonfinancial assets and liabilities that are measured and reported on a fair value basis into one of the following three levels:

Level 1 – Unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.

Level 2 – Inputs other than quoted prices in Level 1 that are either for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability, or inputs that are derived principally from or corroborated by observable market data by correlation or other means.

Level 3 – Unobservable inputs for the asset or liability where there is little, if any, market activity for the asset or liability at the measurement date, which require the Company to develop its own assumptions.

The fair value hierarchy gives the highest priority to unadjusted quoted prices in active markets (Level 1) and the lowest priority to unobservable inputs (Level 3). All fair value disclosures are categorized within one of the three categories in the hierarchy based on the lowest level that is significant to the valuation.

The fair value of the interest rate swaps are determined by using the counterparty's proprietary models that can include observable quoted market interest rates and interest rate futures as well as certain assumptions regarding past, present and future market conditions.

Under the asset management contract, a timing difference can exist between the payment for natural gas purchases and the actual receipt of such purchases. Payments are made based on a predetermined monthly volume with the price based on weighted average first of the month index prices corresponding to the month of the scheduled payment. At June 30, 2025 and September 30, 2024, the Company had recorded in accounts payable the estimated fair value of the liability valued at the corresponding first of month index prices for which the liability is expected to be settled.

The Company’s nonfinancial assets and liabilities measured at fair value on a nonrecurring basis consist of its AROs. The AROs are measured at fair value at initial recognition based on expected future cash flows required to settle the obligation.

The carrying value of cash and cash equivalents, accounts receivable, borrowings under line-of-credit, accounts payable, customer credit balances and customer deposits is a reasonable estimate of fair value due to the short-term nature of these financial instruments. In addition, the carrying amount of the variable rate line-of-credit is a reasonable approximation of its fair value.

The fair value of long-term debt is estimated by discounting the future cash flows of the fixed rate debt based on the underlying treasury rate or other treasury instruments with a corresponding maturity period and estimated credit spread extrapolated based on market conditions since the issuance of the debt.

ASC 825, Financial Instruments, requires disclosures regarding concentrations of credit risk from financial instruments. Cash equivalents are investments in high-grade, short-term securities (original maturity less than three months), placed with financially sound institutions. Accounts receivable are from a diverse group of customers including individuals and small and large companies in various industries. No individual customer amounted to more than 5% of total accounts receivable at June 30, 2025 and September 30, 2024. The Company maintains certain credit standards with its customers and requires a customer deposit, if warranted.

10. | Earnings Per Share

Basic EPS for the three and nine months ended June 30, 2025 and 2024 was calculated by dividing net income by the weighted-average common shares outstanding during the period. Diluted EPS was calculated by dividing net income by the weighted-average common shares outstanding during the period plus potential dilutive common shares. Potential dilutive common shares are calculated in accordance with the treasury stock method, which assumes that proceeds from the exercise of all options are used to repurchase common stock at market value. The number of shares remaining after the proceeds are exhausted represents the potentially dilutive effect of the securities. The computation of diluted EPS for the three months ended June 30, 2025 and 2024 excludes potentially dilutive shares of 1,695 and 2,164 respectively, and 2,000 and 2,793, respectively, for the nine months ended June 30, 2025 and 2024, because to include them would be antidilutive for the periods. However, these shares could potentially dilute EPS in the future.

12. | Income Taxes

The effective tax rates for the three-month and nine-month periods ended June 30, 2025 and 2024 reflected in the table below are less than the combined federal and state statutory rate of 25.74%. The reduction to the effective tax rates is due to additional tax deductions from the amortization of excess deferred taxes and amortization of RNG tax credits deferred as a regulatory liability.

|  | Three Months Ended June 30, |  |  | Nine Months Ended June 30, |
|  | 2025 |  |  | 2024 |  |  | 2025 |  |  | 2024 |
Effective tax rate |  |  | 23.1 | % |  |  | 23.1 | % |  |  | 23.4 | % |  |  | 23.5 | %

ASC 740 provides for the determination of whether tax benefits claimed or expected to be claimed on a tax return should be recognized in the financial statements. The Company has a reserve recorded for unrecognized tax benefits of $273,936 as of June 30, 2025 and September 30, 2024 related to tax positions taken in the Company's prior tax returns. The Company has evaluated its tax positions for the three and nine months ended June 30, 2025 and determined no additional reserve for unrecognized tax benefits was necessary. A reconciliation of the Company's unrecognized tax benefits is as follows:

Balance at September 30, 2024 |  | $ | 273,936 |
Increase resulting from prior period tax positions |  |  | — |
Balance at June 30, 2025 |  | $ | 273,936 |

The Company’s policy is to classify interest associated with uncertain tax positions as interest expense in the financial statements. Tax penalties, if any, are netted against other income.

The Company files a consolidated federal income tax return and state income tax returns in Virginia and West Virginia, and thus subject to examinations by federal and state tax authorities. The IRS is currently examining the Company's 2018 and 2019 amended federal tax returns. The focus of the examination relates to research and development credits, and the final results of the examination have not been presented to the Company as of the date of this Form 10-Q. The Company believes its income tax assets and liabilities are fairly stated as of June 30, 2025 and September 30, 2024; however, these assets and liabilities could be adjusted as a result of this examination. The Company's amended federal returns for fiscal 2018 and 2019 remain open related to the examination. Aside from these exceptions, the federal returns and the state returns for Virginia and West Virginia for the tax years ended prior to September 30, 2022 are no longer subject to examination.

13. | Regulatory Assets and Liabilities

The Company’s regulated operations follow the accounting and reporting requirements of ASC 980, Regulated Operations. A regulated company may defer costs that have been or are expected to be recovered from customers in a period different from the period in which the costs would ordinarily be charged to expense by an unregulated enterprise. When this situation occurs, costs are deferred as assets in the condensed consolidated balance sheet (regulatory assets) and amortized into expense over periods when such amounts are reflected in customer rates. Additionally, regulators can impose liabilities upon a regulated company for amounts previously collected from customers and for current collection in customer rates of costs that are expected to be incurred in the future (regulatory liabilities). In the event the provisions of ASC 980 no longer apply to any or all regulatory assets or liabilities, the Company would write off such amounts and include the effects in the condensed consolidated statements of income and comprehensive income in the period which ASC 980 no longer applied.

14. | Commitments and Contingencies

Roanoke Gas currently holds the only franchises and/or CPCNs to distribute natural gas in its service area. These franchises generally extend for multi-year periods and are renewable by the municipalities, including exclusive franchises in the cities of Roanoke and Salem and the Town of Vinton, Virginia. All three franchises are set to expire December 31, 2035.

RGC RESOURCES, INC. AND SUBSIDIARIES

Due to the nature of the natural gas distribution business, the Company has entered into agreements with both suppliers and pipelines for natural gas commodity purchases, storage capacity and pipeline delivery capacity. Through March 31, 2025, the Company utilized two asset managers to assist in optimizing the use of its transportation, storage rights and gas supply in order to provide a secure and reliable source of natural gas to its customers. Those services were consolidated to one asset manager as of April 1, 2025. The Company also has storage and pipeline capacity contracts to store and deliver natural gas to the Company’s distribution system. Roanoke Gas is currently served directly by three primary pipelines that deliver the natural gas supplied to the Company’s distribution system. Depending on weather conditions and the level of customer demand, failure of one of these transmission pipelines could have a major adverse impact on the Company's ability to deliver natural gas to its customers and its results of operations.

15. | Employee Benefit Plans

The Company has both a pension plan and a postretirement plan. The pension plan covers the Company’s employees hired before January 1, 2017 and provides a retirement benefit based on years of service and employee compensation. The postretirement plan, covering employees hired before January 1, 2000, provides certain health care and supplemental life insurance benefits to retired employees who meet specific age and service requirements. Net pension plan and postretirement plan expense is detailed as follows:

The components of net periodic benefit cost, excluding the service cost component, are included in other income, net in the condensed consolidated statements of income. Service cost is included in operations and maintenance expense in the condensed consolidated statements of income.

No funding contributions were made to the pension plan or postretirement plan for the periods presented in the tables above. The Company is not currently planning to make any funding contributions to either plan for the remainder of fiscal 2025.

16. | Leases

The Company has four leases for certain assets including office space and land classified as operating leases with original terms ranging from 3 to 20 years. The Company entered into a new lease during the period, which is a continuation of a prior lease. The Company determines if an arrangement is a lease at inception of the agreement based on the terms and conditions in the contract. The operating lease ROU assets and operating lease liabilities are recognized at the present value of the future minimum lease payments over the lease term at commencement date. As most of the leases do not provide an implicit rate, the Company uses an estimate of its secured incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. The incremental borrowing rate is determined by management aided by inquiries of a third party.

Lease expense for minimum lease payments is recognized on a straight-line basis over the term of the agreement. The Company made an accounting policy election that payments under agreements with an initial term of 12 months or less will not be included on the condensed consolidated balance sheet but will be recognized when paid in the consolidated statements of operations.

Overview

Resources is an energy services company primarily engaged in the regulated sale and distribution of natural gas to approximately 62,700 residential, commercial and industrial customers in Roanoke, Virginia and surrounding localities through its Roanoke Gas subsidiary. Midstream, a wholly owned subsidiary of Resources, is a less than 1% investor in both the MVP and Southgate. The utility operations of Roanoke Gas are regulated by the SCC, which oversees the terms, conditions and rates charged to customers for natural gas service, safety standards, extension of service and depreciation. The Company is also subject to regulation from the United States Department of Transportation in regard to the construction, operation, maintenance, safety and integrity of its transmission and distribution pipelines. FERC regulates the prices for the transportation and delivery of natural gas to the Company’s distribution system and underground storage services. In addition, the Company is subject to other regulations which are not necessarily industry specific.

Nearly all of the Company’s revenues are derived from the sale and delivery of natural gas to Roanoke Gas customers based on rates and fees authorized by the SCC. These rates are designed to provide the Company with the opportunity to recover its gas and non-gas expenses and to earn a reasonable rate of return for shareholders based on normal weather. These rates are determined based on various rate applications filed with the SCC. Generally, investments related to extending service to new customers are recovered through the additional revenues generated by the non-gas base rates in place at that time. The investment in replacing and upgrading existing non-SAVE infrastructure, as well as recovering increases in non-gas expenses due to inflationary pressures, regulatory requirements or operational needs, are generally not recoverable until a formal rate application is filed to include the additional investment and higher costs, and new non-gas base rates are approved.

On February 2, 2024, primarily in response to continued inflationary pressures, Roanoke Gas filed for an annual non-gas base rate increase of $4.33 million. The filing also reflected an increase in the Company's authorized return on equity from 9.44% to 10.35%. The new interim non-gas base rates went into effect for customer billings on or after July 1, 2024, subject to refund. On October 16, 2024, the Company reached a settlement with the SCC staff on all outstanding issues in the case. Under the terms of the settlement, the Company agreed to an annual incremental revenue requirement increase of $4.08 million based on a return on equity of 9.90%. On April 10, 2025, the SCC issued a final order approving the settlement in its entirety. The order also directed Roanoke Gas to refund the excess revenues collected during the time the interim rates were in effect with interest. The refunds to customers, which had previously been accrued as a regulatory liability, were made to customers in May 2025.

As the Company’s business is seasonal in nature, volatility in winter weather and the commodity price of natural gas can impact the effectiveness of the Company’s rates in recovering its costs and providing a reasonable return for its shareholders. In order to mitigate the effect of weather variations and other factors not provided for in the Company's base rates, Roanoke Gas has certain approved rate mechanisms in place that help provide stability in earnings, adjust for volatility in the price of natural gas and provide a return on qualified infrastructure investment. These mechanisms include the SAVE Rider, WNA, ICC, RNG Rider and PGA.

The SAVE Plan and Rider provides the Company with a mechanism through which it recovers costs related to qualified SAVE infrastructure investments on a prospective basis, until a rate application is filed incorporating these investments in non-gas base rates. Roanoke Gas filed and received approval from the SCC for an updated annual SAVE Rider rate which became effective October 1, 2024. As a result of the updated SAVE Rider, SAVE Plan revenues increased by approximately $299,000 and $855,000, respectively, for the three-month and nine-month periods ended June 30, 2025 compared to the same periods last year when the recovery of all prior SAVE Plan investment was incorporated into the non-gas base rates that were effective January 1, 2023. The updated SAVE Rider is expected to result in approximately $1,489,000 of annualized SAVE-related revenues during fiscal 2025. Additional information regarding the SAVE Plan and Rider is provided in Note 4 of the condensed consolidated financial statements.

The WNA mechanism reduces the volatility in earnings due to the variability in temperatures during the heating season. The WNA is based on the most recent 30-year temperature average and provides the Company with a level of earnings protection when weather is warmer than normal and provides its customers with price protection when weather is colder than normal. The WNA allows the Company to recover from its customers the lost margin (excluding gas costs) from warmer-than-normal weather and correspondingly requires the Company to refund the excess margin earned for colder-than-normal weather. The WNA mechanism used by the Company is based on a linear regression model that determines the value of a single heating degree day and thereby estimates the revenue adjustment based on weather variance from normal. Any billings or refunds related to the WNA are completed following each WNA year, which extends for the 12-month period from April to March. For the three and nine months ended June 30, 2025, the Company accrued approximately $493,000 and $966,000 in additional revenues under the WNA model for weather that was 22% and 4% warmer than normal, respectively, compared to approximately $821,000 and $3,689,000 in additional revenues for weather that was 48% and 19% warmer than normal for the corresponding periods last year. The adjusted WNA balance for the 12-month period ended March 31, 2025 was approximately $1,473,000, and was collected from customers during May and June 2025.

The Company has an approved rate structure to mitigate the impact of the financing costs of its natural gas inventory. Under this rate structure, Roanoke Gas recognizes revenue by applying the ICC factor, based on the Company’s weighted-average cost of capital, including interest rates on short-term and long-term debt, and the Company’s authorized return on equity, to the average cost of natural gas inventory during the period. Total ICC revenues decreased by approximately $44,000 and $145,000 for the three-month and nine-month periods ended June 30, 2025 compared to the corresponding periods last year, due to lower natural gas commodity prices during the 2024 summer storage injection season resulting in a lower average cost of natural gas in storage and lower storage balances in the second and third quarters of fiscal 2025. Accordingly, fiscal 2025 and 2026 ICC revenues are expected to continue to remain below last year's levels.

In March 2023, Roanoke Gas began operating the RNG facility, through a cooperative agreement with the Western Virginia Water Authority, to produce commercial quality RNG for delivery into its distribution system. Roanoke Gas is allowed to recover the costs associated with the investment in RNG facilities and the related operating costs through an RNG Rider added to customer bills. Customers receive the benefit of environmental credits generated through the production of RNG. Roanoke Gas recognized approximately $479,000 and $1,296,000 in RNG revenue for the three and nine months ended June 30, 2025 compared to approximately $394,000 and $1,211,000 for the corresponding periods in the prior year.

The cost of natural gas, which is a pass-through cost, is independent of the Company's non-gas rates. Accordingly, the Company's approved billing rates include a component designed to allow for the recovery of the cost of natural gas used by its customers. This rate component, referred to as the PGA, allows the Company to pass along to its customers increases and decreases in natural gas costs through a quarterly filing, or more frequent if necessary, once SCC staff approval is received. As actual costs will differ from the projections used in establishing the PGA rate, the Company will either over-recover or under-recover its actual gas costs during the period. The difference between actual costs incurred and costs recovered through the application of the PGA is recorded as a regulatory asset or liability. At the end of the annual deferral period, the balance is amortized over a succeeding 12-month period through the ensuing non-gas rate component.

Results of Operations

The analysis on the results of operations is based on the consolidated operations of the Company, which is primarily associated with the utility segment. Additional segment analysis is provided when Midstream's investment in affiliates represents a significant component of the comparison.

The Company's operating revenues are affected by the cost of natural gas, as reflected in the condensed consolidated statements of income under cost of gas - utility. The cost of natural gas, which includes commodity price, transportation, storage, injection and withdrawal fees, with any increase or decrease offset by a correlating change in revenue through the PGA, is passed through to customers at cost. Accordingly, management believes that gross utility margin, a non-GAAP financial measure defined as utility revenues less cost of gas, is a useful and relevant measure to analyze financial performance. The term gross utility margin is not intended to represent or replace gross margin, the most comparable GAAP financial measure, as an indicator of operating performance and is not necessarily comparable to similarly titled measures reported by other companies. A reconciliation between gross utility margin and gross margin is presented under the Gross Utility Margin section below. The following results of operations analyses will reference gross utility margin.

Three Months Ended June 30, 2025:

Net income increased by $381,720 for the three months ended June 30, 2025, compared to the same period last year, primarily due to increased equity earnings from the MVP as the project was service for the entire quarter in fiscal 2025 compared to less than a month during the same period in the prior year.

The tables below reflect operating revenues, volume activity and heating degree days.

Total operating revenues for the three months ended June 30, 2025, compared to the same period last year, increased by approximately 19% primarily due to higher gas costs, delivered volumes and SAVE revenues, along with the implementation of a non-gas base rate increase, slightly offset by a decrease in WNA revenue. Gas costs were the main contributing factor to the increase in operating revenues over the prior period primarily due to pipeline capacity charges increasing over $2,000,000 as a result of higher rates and MVP capacity. Pipeline capacity charges, which do not impact margin, increased meaningfully during the period, subject to refund, due to FERC rate increase proceedings. While the Company is unable to predict the ultimate outcome, these costs and potential refunds will be passed through to customers. In addition, SAVE Plan revenues increased as Roanoke Gas continues to invest in qualified SAVE infrastructure projects, resulting in approximately $299,000 more revenue compared to the same period in the prior year. Transportation and interruptible volumes increased 15% primarily driven by business activity of a single, multi-fuel customer during the quarter. The Company expects this customer's usage to remain elevated in the near term, although much of this volume has a lower margin contribution. These increased volumes, coupled with the non-gas base rate increase implemented in July 2024, contributed to an approximate $272,000 increase in non-gas volumetric revenues. WNA revenues declined approximately $328,000 from the corresponding period last year as weather was 22% warmer than the 30-year normal during the current period compared to 48% warmer than normal during the prior period.

Gross utility margin increased over the same period last year primarily as a result of the aforementioned increases in SAVE revenues, as well as increased RNG revenues, slightly offset by the reduction in ICC revenues. As discussed in the Overview section, the WNA model adjusts for the impact of variability of temperatures during the heating season. The WNA model calculates what the corresponding volumes would be if temperatures were equivalent to the 30-year normal during each period and adjusts for the difference in margin from normal. In applying the WNA model to both the current and prior years, the volumetric margin, net of the WNA, decreased slightly by approximately $56,000 due a decrease of 17% in WNA adjusted residential and commercial delivered volumes. The SAVE Plan and RNG Riders contributed an additional $299,000 and $85,000, respectively, to margin, while ICC revenues decreased by approximately $44,000 due to lower cost of gas in storage.

The changes in the components of gas utility margin are summarized below:

Operations and maintenance expenses increased $366,011, or 9%, from the same period last year. Personnel costs increased by approximately $166,000 due to increased staffing and the inflationary impact on salaries and benefits. Contracted services increased by approximately $83,000 also due to inflationary pressures. These increases were slightly offset by a decrease in professional services expenses. Costs associated with the RNG facility increased approximately $104,000.

Taxes other than income taxes increased by $118,077, or 19%, due to higher property taxes associated with growth in utility property and increased valuations.

Depreciation expense increased by $211,637, or 8%, consistent with an increase in utility property balances.

Equity in earnings of unconsolidated affiliate increased by $489,478. With the MVP in service, the Company now recognizes its share of operational earnings from the MVP, favorably adjusted for the amortization of a basis difference that arose when the Company recorded an other-than-temporary impairment of its investment in 2022, which exceeded the amount of AFUDC recognized during the prior period as construction activities were winding down at the end of the project. See Note 5 of the consolidated financial statements for additional information related to the MVP.

Other income, net increased by $313,349 primarily due to an approximate $284,000 decrease in benefit plan costs other than service cost, coupled with an increase of approximately $68,000 in revenue sharing related to the asset management agreement, which is described in more detail in the Asset Management section.

Interest expense decreased by $54,339, or 4%, as the weighted-average interest rate on total debt decreased from 4.42% during the third quarter of fiscal 2024 to 4.12% during the third quarter of fiscal 2025. Roanoke Gas' interest expense decreased by $45,984, or 5%, as total average debt outstanding decreased by approximately $2,671,000 associated with net payments on the Company's line-of-credit. See Notes 6 and 7 of the consolidated financial statements for more information on the Company's debt.

Income tax expense increased by $114,413 corresponding to the increase in pre-tax income. The effective tax rate was 23.1% for the three-month periods ended June 30, 2025 and 2024. The effective tax rate is below the combined statutory state and federal rate due to the amortization of excess deferred taxes and tax credits.

Nine Months Ended June 30, 2025:

Net income increased by $1,864,235 for the nine months ended June 30, 2025, compared to the same period last year, primarily due to the implementation of higher non-gas base rates and increased natural gas deliveries, partially offset by lower WNA revenues and lower equity earnings from the MVP as the project transitioned from construction to in service, as well as lower benefit plan costs.

Total operating revenues for the nine months ended June 30, 2025, compared to the same period last year, increased by approximately 13% primarily due to the implementation of a non-gas base rate increase, along with higher delivered volumes, gas costs and SAVE revenues, partially offset by a decrease in WNA revenue. The non-gas base rate increase implemented in 2024 was the main contributing factor to an approximate $5.4 million increase in non-gas volumetric revenues. In addition, total heating degree days increased by 18% from the same period last year, resulting in a 9% increase in the weather-sensitive residential and commercial volumes, while transportation and interruptible volumes increased 28%, primarily driven by business activity of a single, multi-fuel customer during the period. Total gas costs also increased over the prior period primarily due to pipeline capacity charges increasing over $3.7 million as a result of higher rates and MVP capacity. SAVE Plan revenues increased as Roanoke Gas continues to invest in qualified SAVE infrastructure projects, resulting in approximately $855,000 more revenue compared to the same period in the prior year. WNA revenues declined approximately $2.7 million from the corresponding period last year as weather was only 4% warmer than normal during the current period compared to 20% warmer than normal during the prior period.

Gross utility margin increased over the same period last year primarily as a result of the implementation of new non-gas base rates and increases in SAVE revenues, slightly offset by the reduction in ICC revenues. The volumetric margin, net of the WNA, increased by approximately $2.7 million primarily due to the new non-gas base rates and increases in transportation and interruptible volumes. The SAVE Plan contributed an additional $855,000 to margin, while ICC revenues decreased by approximately $145,000 due to lower cost of gas in storage.

Operations and maintenance expenses increased by $720,021, or 5%, from the same period last year primarily due to inflationary effects on personnel costs and contracted services, and lower capitalized overheads. Personnel costs and contracted services increased by approximately $367,000 due to increased staffing and the inflationary impact on salaries and benefits, as well as third party services. Total capitalized overheads declined by approximately $179,000 due to a reduction in direct construction expenditures related to Roanoke Gas capital projects compared to the same period last year and lower overheads capitalized as part of LNG due to timing of production. Increased RNG expenses, corporate insurance premiums and bad debt expense associated with the higher accounts receivable balances accounted for much of the remaining cost increase.

Taxes other than income taxes increased by $319,622, or 16%, primarily due to higher property taxes associated with growth in utility property and increased valuations.

Depreciation expense increased by $516,351, or 6%, consistent with an increase in utility property balances.

Equity in earnings of unconsolidated affiliate decreased by $552,353, or 19%. With the MVP in service, the Company now recognizes its share of operational earnings from the MVP, favorably adjusted for the amortization of a basis difference that arose when the Company recorded an other-than-temporary impairment of its investment in 2022. These in-service earnings did not fully replace the amount of AFUDC recognized while construction activities were ongoing during the first eight months of fiscal 2024. See Note 5 of the consolidated financial statements for additional information related to the MVP.

Other income, net increased by $1,040,045 primarily due to an approximate $848,000 decrease in benefit plan costs other than service cost, coupled with an increase of approximately $270,000 in revenue sharing related to the asset management agreements, which are described in more detail in the Asset Management section.

Interest expense increased by $152,980, or 3%, primarily due to higher borrowing levels, along with higher interest rates on the Company's variable-rate debt. Total average debt outstanding during the first nine months of fiscal 2025 increased by 4% from the first nine months of fiscal 2024. Roanoke Gas' total average debt outstanding increased by approximately $2,445,000 associated with net borrowings under the Company's line-of-credit, while Midstream's total average debt outstanding increased by approximately $2,170,000 during the period. There were minimal fluctuations in the weighted-average interest rates between the periods. See Notes 6 and 7 of the consolidated financial statements for more information on the Company's debt.

Income tax expense increased by $555,661, or 16%, corresponding to an increase in pre-tax income. The effective tax rate was 23.4% and 23.5% for the nine-month periods ended June 30, 2025 and 2024, respectively. The effective tax rate is below the combined statutory state and federal rate due to the amortization of excess deferred taxes and tax credits.

Asset Management

Roanoke Gas uses a third-party asset manager to oversee its pipeline transportation, storage rights and gas supply inventories and deliveries in order to provide a secure and reliable source of natural gas to its customers. In return for utilizing the excess capacities of the transportation and storage rights, the asset manager pays Roanoke Gas a monthly utilization fee. In accordance with an SCC order issued in 2018, a portion of the utilization fee is retained by the Company with the balance passed through to customers through reduced gas costs. On March 26, 2025, the Company entered into a new asset manager agreement effective April 1, 2025 and is set to expire on March 31, 2028.

Equity Investment in Mountain Valley Pipeline

The Company has a less than 1% interest in the MVP, which is accounted for as an equity investment, and a less than 1% interest in the Southgate pipeline, which is contemplated to interconnect with the MVP and accounted for under the cost method.

From inception through May 2024, earnings from the LLC were primarily attributable to AFUDC income. With the MVP in operation, the Company recognizes its share of earnings from the LLC, favorably adjusted for a basis difference between the Company's proportional share of assets and its carrying value that arose when the Company recorded an other-than-temporary impairment of its investment in 2022. This basis difference amortization is a favorable non-cash adjustment over the operational life of the MVP, or 40 years. For the three and nine months ended June 30, 2025, the Company recorded equity in earnings of consolidated affiliate of approximately $772,000 and $2.4 million, respectively, compared to $283,000 and $3.0 million for the same periods in 2024, with the 2024 amounts being derived from AFUDC. Midstream has received quarterly cash distributions of its share from the LLC totaling approximately $2.7 million during the first nine months of fiscal 2025 which was a return on its invested capital. Future quarterly distributions are expected to be of a similar magnitude. The Company is using this cash to pay interest and other expenditures related to Midstream.

Regulatory

See Note 4 of the condensed consolidated financial statements for discussion on Regulatory matters.

Capital Resources and Liquidity

Due to the capital-intensive nature of the utility business, as well as the impact of weather variability, the Company’s primary capital needs are the funding of its capital projects, the seasonal funding of its natural gas inventories and accounts receivables, debt service and payments of dividends to shareholders. The Company anticipates funding these items through its operating cash flows, credit availability under short-term and long-term debt agreements and proceeds from the sale of its common stock.

Cash and cash equivalents increased by $1,232,704 for the nine-month period ended June 30, 2025 compared to an increase of $1,028,662 for the nine-month period ended June 30, 2024. The following table summarizes the sources and uses of cash:

Cash Flows Provided by Operating Activities:

The seasonal nature of the natural gas business causes operating cash flows to fluctuate significantly during the year as well as from year-to-year. Factors, including weather, energy prices, natural gas storage levels and customer collections, contribute to working capital levels and related cash flows. Generally, operating cash flows are positive during the second and third fiscal quarters as a combination of earnings, declining storage gas levels and collections on customer accounts contribute to higher cash inflows. During the first and fourth fiscal quarters, operating cash flows generally decrease due to increases in natural gas storage levels and rising customer receivable balances.

Cash flows from operating activities for the nine months ended June 30, 2025 increased by $11,216,830 compared to the same period last year. The table below summarizes the significant components of operating cash flows:

|  | Nine Months Ended June 30, |  |  | Increase/ |
Cash Flow From Operating Activities: |  | 2025 |  |  | 2024 |  |  | (Decrease) |

The increase in operating cash flows is primarily due to higher net income and the cash distributions received from the LLC, along with direct impacts from weather and increased pipeline and storage capacity charges. During the first nine months of fiscal 2025, the Company received approximately $2,659,000 in quarterly cash distributions from the LLC, which was has been accounted for as a return on its invested capital. In addition, colder weather and increased gas costs compared to the same period last year resulted in higher accounts receivable and accounts payable balances. Pipeline and storage capacity charges during the first nine months of fiscal 2025 increased over $3,100,000 from the same period in the prior year. Additionally, total commodity costs increased from $3.53 per DTH in the first nine months of fiscal 2024 to $3.69 per DTH in the first nine months of fiscal 2025. WNA revenues for the first nine months of fiscal 2025 declined by approximately $2.7 million from the same period last year corresponding to an 18% increase in the number of heating degree days between periods. This decline in WNA receivable contributed $2.0 million in additional operating cash. In December 2024, the Company received an approximate $890,000 supplier refund, resulting from a FERC rate case settlement, from one of the interstate pipelines that supplies the Company with natural gas.

Cash Flows Used in Investing Activities:

Investing activities primarily consist of expenditures related to Roanoke Gas' utility property, which includes replacing aging natural gas pipe with new plastic or coated steel pipe, improvements to the LNG plant and gas distribution system facilities and expansion of its natural gas system to meet new customer demand. The Company is continuing its focus on SAVE infrastructure replacement projects, including the replacement of pre-1973 first generation plastic pipe. New customer demand for natural gas continues to be steady and therefore extending the natural gas distribution system within its service territory is also a priority. Roanoke Gas' total capital expenditures for the nine-month period ended June 30, 2025 were approximately $15.7 million compared to $16.6 million during the same period last year. Total fiscal 2025 capital expenditures are expected to be approximately $22 million. Midstream continues to be invested in the LLC; however, the Company did not make capital contributions in 2024 or 2025 under a prior agreement with the LLC's managing partner. Accordingly, Midstream's ownership percentage declined during the remaining construction period of the project. Now that the MVP is in service, Midstream will incur periodic, future capital investment related to ongoing MVP operations requirements and system improvements. Midstream has and will continue to make capital investments in Southgate. The targeted timing for completion of the Southgate project is 2028.

Cash Flows Provided by Financing Activities:

Financing activities generally consist of borrowings and repayments under credit agreements, issuance of common stock and the payment of dividends. Net cash flows used in financing activities were approximately $11.3 million for the nine months ended June 30, 2025, compared to $517,000 in net cash flows provided by financing activities for the same period last year. The $11.8 million decrease in financing cash flows is primarily attributable to net payments of $6.2 million under Roanoke Gas' line-of-credit during the first nine months of fiscal 2025 compared to net borrowings of $3.3 million in the same period last year.

In addition, Resources issued a total of 74,057 shares of common stock resulting in net proceeds of approximately $1.5 million. No shares were issued through the ATM program during the first nine months of fiscal 2025. During the same period last year, Resources issued 177,906 shares for approximately $3.5 million, including 85,501 shares through the ATM program for approximately $1.7 million, net of fees.

Management regularly evaluates the Company’s liquidity through a review of its available financing resources and its cash flows. Resources maintains the ability to raise equity capital through its ATM program, private placement or other public offerings. Management believes Roanoke Gas has access to sufficient financing resources to meet its cash requirements for the next year, including the line of credit and the two private shelf facilities. Roanoke Gas may also adjust capital spending if such a need would arise.

With the MVP in service, Midstream's future cash requirements will relate to regular monthly operating expenses, debt service and capital contributions. The Company has received three quarterly cash distributions from MVP totaling approximately $2.7 million during the first nine months of fiscal 2025, and going forward should receive similar distributions quarterly. Subsequent to the end of the quarter, the Company entered into a firm letter of commitment with two banks for long-term structures related to the debt that supports its investment in Midstream as discussed more fully in Note 7. Under the letter of commitment, Midstream will enter into a new loan with a seven-year term bearing an interest rate of SOFR plus 1.55%. In addition to interest, Midstream will repay principal based on a schedule aligned with the MVP shipper contracts, which expire in June 2044 and will approximate $2.8 million annually. With these firm commitments, the Company has classified all debt related to Midstream as long-term except for $2.5 million of principal amortization expected in the coming 12 months. Covenants on these facilities are similar to the existing arrangements. The Company expects to consummate the arrangement in the fourth quarter of fiscal 2025.

The Company believes this new debt structure in conjunction with cash distributions from MVP and support from RGC Resources, as needed, will enable Midstream to satisfy all of its obligations, including amortization, while the LLC works to increase cash flows. The Company believes this will enhance the value of the Company's investment.

As of June 30, 2025, Resources' long-term capitalization ratio was 45% equity and 55% debt.

ITEM 4 – CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

The Company maintains disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) that are designed to be effective in providing reasonable assurance that information required to be disclosed in reports under the Exchange Act are identified, recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC, and that such information is accumulated and communicated to management to allow for timely decisions regarding required disclosure.

Through June 30, 2025, the Company has evaluated, under the supervision and with the participation of management, including the chief executive officer and the chief financial officer, the effectiveness of the design and operation of the Company’s disclosure controls and procedures. Based upon that evaluation, the chief executive officer and chief financial officer concluded that the Company’s disclosure controls and procedures were effective at the reasonable assurance level as of June 30, 2025.

Changes in Internal Control over Financial Reporting

On April 1, 2025, the Company implemented a new enterprise resource planning (“ERP”) system, which replaced the existing ERP system, to improve the efficiency of certain financial and related transactional processes; this system did not replace the system of record for revenue transactions with customers. In connection with this implementation, the Company has enhanced its processes and procedures, which has resulted in changes to internal control over financial reporting, to align with the upgraded system functionality. The Company will continue to monitor and evaluate the operating effectiveness of the related controls during subsequent periods.

Management routinely reviews the Company’s internal control over financial reporting and makes changes, as necessary, to enhance the effectiveness of the internal controls. Except for the implementation of the new ERP system, there were no other changes in internal control over financial reporting that occurred during the three months ended June 30, 2025, that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Limitations on the Effectiveness of Controls

Because of the inherent limitations in an effective internal control system, any control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that it will prevent or detect all misstatements, due to error or fraud, from occurring in the consolidated financial statements. Additionally, management is required to use judgment in evaluating controls and procedures.
