We also have audited the Company's internal control over financial reporting as of September 30, 2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of September 30, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in the period ended September 30, 2023 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of September 30, 2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO. Basis for Opinions The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management's Annual Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions. -63- Definition and Limitations of Internal Control over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate . Critical Audit Matters The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates. The Impact of Proved Natural Gas Reserves on Natural Gas Properties, Net As described in Note A to the consolidated financial statements, the Exploration and Production segment includes capitalized costs relating to natural gas producing activities, net of depreciation, depletion, and amortization (DD&A) of $2.4 billion as of September 30, 2023. The Exploration and Production segment follows the full cost method of accounting. Under this method, all costs associated with property acquisition, exploration and development activities are capitalized and DD&A is computed based on quantities produced in relation to proved reserves using the units of production method. As disclosed by management, in addition to DD&A under the units-of-production method, proved reserves are a major component in the SEC full cost ceiling test. The ceiling test, which is performed each quarter, determines a limit, or ceiling, on the amount of property acquisition, exploration and development costs that can be capitalized. If capitalized costs, net of accumulated DD&A and related deferred income taxes, exceed the ceiling at the end of any quarter, a permanent impairment is required to be charged to earnings in that quarter. There were no ceiling test impairment charges for the year ended September 30, 2023 . As of September 30, 2023, the ceiling exceeded the book value of the natural gas properties by approximately $794.7 million. Estimates of the Company’s proved natural gas reserves and the future net cash flows from those reserves were prepared by the Company’s petroleum engineers and audited by independent petroleum engineers (together referred to as “management’s specialists”). Petroleum engineering involves significant assumptions in the evaluation of available geological, geophysical, engineering and economic data for each reservoir. Estimates of economically recoverable natural gas reserves and of future net cash flows depend upon a number of variable factors and assumptions, including quantities of natural gas that are ultimately recovered, the timing of the recovery of natural gas reserves, the production and operating costs to be incurred, the amount and timing of future development and abandonment expenditures, and the price received for the production. -64- The principal considerations for our determination that performing procedures relating to the impact of proved natural gas reserves on natural gas properties, net is a critical audit matter are the significant judgment by management, including the use of management’s specialists, when developing the estimates of proved natural gas reserves, which in turn led to a high degree of auditor judgment, subjectivity and effort in performing procedures and evaluating evidence related to data, methods, and assumptions used by management and its specialists in developing the estimates of proved natural gas reserves and the related assumption of quantities of proved natural gas that are ultimately recovered. Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to management’s estimates of proved natural gas reserves and the related assumption of quantities of proved natural gas that are ultimately recovered which is utilized in the DD&A expense and ceiling test calculations. These procedures also included, among others, evaluating the reasonableness of the significant assumption used by management related to the quantities of proved natural gas that are ultimately recovered which included evaluating information on additional development activity, production history, if the assumption used was reasonable considering the past performance of the Company, and whether it was consistent with evidence obtained in other areas of the audit. The work of management’s specialists was used in performing the procedures to evaluate the reasonableness of the estimates of proved natural gas reserves and the related assumption of quantities of proved natural gas that are ultimately recovered. As a basis for using this work, the specialists’ qualifications were understood and the Company’s relationship with the specialists assessed. The procedures performed also included evaluation of the methods and assumptions used by the specialists, tests of the completeness and accuracy of data used by the specialists and an evaluation of the specialists’ findings. /s/ P RICEWATERHOUSE C OOPERS LLP Buffalo, New York November 17, 2023 We have served as the Company’s auditor since 1941. -65- NATIONAL FUEL GAS COMPANY CONSOLIDATED STATEMENTS OF INCOME AND EARNINGS REINVESTED IN THE BUSINESS Year Ended September 30 2023 2022 2021 (Thousands of dollars, except per common share amounts) INCOME Operating Revenues: Utility and Energy Marketing Revenues $ 941,779 $ 897,916 $ 667,549 Exploration and Production and Other Revenues 958,455 1,010,629 837,597 Pipeline and Storage and Gathering Revenues 273,537 277,501 237,513 2,173,771 2,186,046 1,742,659 Operating Expenses: Purchased Gas 437,595 392,093 171,827 Operation and Maintenance: Utility and Energy Marketing 205,239 193,058 179,547 Exploration and Production and Other 124,270 191,572 173,041 Pipeline and Storage and Gathering 149,247 136,571 123,218 Property, Franchise and Other Taxes 92,700 101,182 94,713 Depreciation, Depletion and Amortization 409,573 369,790 335,303 Impairment of Oil and Gas Producing Properties — — 76,152 1,418,624 1,384,266 1,153,801 Gain on Sale of Assets — 12,736 51,066 Operating Income 755,147 814,516 639,924 Other Income (Expense): Other Income (Deductions) 18,138 ( 1,509 ) ( 15,238 ) Interest Expense on Long-Term Debt ( 111,948 ) ( 120,507 ) ( 141,457 ) Other Interest Expense ( 19,938 ) ( 9,850 ) ( 4,900 ) Income Before Income Taxes 641,399 682,650 478,329 Income Tax Expense 164,533 116,629 114,682 Net Income Available for Common Stock 476,866 566,021 363,647 EARNINGS REINVESTED IN THE BUSINESS Balance at Beginning of Year 1,587,085 1,191,175 991,630 2,063,951 1,757,196 1,355,277 Dividends on Common Stock ( 178,095 ) ( 170,111 ) ( 164,102 ) Balance at End of Year $ 1,885,856 $ 1,587,085 $ 1,191,175 Earnings Per Common Share: Basic: Net Income Available for Common Stock $ 5.20 $ 6.19 $ 3.99 Diluted: Net Income Available for Common Stock $ 5.17 $ 6.15 $ 3.97 Weighted Average Common Shares Outstanding: Used in Basic Calculation 91,748,890 91,410,625 91,130,941 Used in Diluted Calculation 92,285,918 92,107,066 91,684,583 See Notes to Consolidated Financial Statements -66- NATIONAL FUEL GAS COMPANY CONSOLIDATED STATEMENTS OF COMPREHENSIVE INCOME Year Ended September 30 2023 2022 2021 (Thousands of dollars) Net Income Available for Common Stock $ 476,866 $ 566,021 $ 363,647 Other Comprehensive Income (Loss), Before Tax: Increase (Decrease) in the Funded Status of the Pension and Other Post-Retirement Benefit Plans ( 9,660 ) 9,561 17,862 Reclassification Adjustment for Amortization of Prior Year Funded Status of the Pension and Other Post-Retirement Benefit Plans 1,674 11,054 16,229 Unrealized Gain (Loss) on Derivative Financial Instruments Arising During the Period 708,206 ( 1,050,831 ) ( 665,371 ) Reclassification Adjustment for Realized (Gains) Losses on Derivative Financial Instruments in Net Income 88,656 882,581 83,711 Other Post-Retirement Adjustment for Regulatory Proceeding — ( 7,351 ) — Other Comprehensive Income (Loss), Before Tax 788,876 ( 154,986 ) ( 547,569 ) Income Tax Expense (Benefit) Related to the Increase (Decrease) in the Funded Status of the Pension and Other Post-Retirement Benefit Plans ( 2,284 ) 2,169 4,072 Reclassification Adjustment for Income Tax Benefit Related to the Amortization of the Prior Year Funded Status of the Pension and Other Post-Retirement Benefit Plans 411 2,574 3,762 Income Tax Expense (Benefit) Related to Unrealized Gain (Loss) on Derivative Financial Instruments Arising During the Period 214,270 ( 287,608 ) ( 179,028 ) Reclassification Adjustment for Income Tax Benefit (Expense) on Realized Losses (Gains) from Derivative Financial Instruments in Net Income 5,806 241,559 22,465 Income Tax Expense (Benefit) Related to Other Post-Retirement Adjustment for Regulatory Proceeding — ( 1,544 ) — Income Taxes — Net 218,203 ( 42,850 ) ( 148,729 ) Other Comprehensive Income (Loss) 570,673 ( 112,136 ) ( 398,840 ) Comprehensive Income (Loss) $ 1,047,539 $ 453,885 $ ( 35,193 ) See Notes to Consolidated Financial Statements -67- NATIONAL FUEL GAS COMPANY CONSOLIDATED BALANCE SHEETS At September 30 2023 2022 (Thousands of dollars) ASSETS Property, Plant and Equipment $ 13,635,303 $ 12,551,909 Less — Accumulated Depreciation, Depletion and Amortization 6,335,441 5,985,432 7,299,862 6,566,477 Current Assets Cash and Temporary Cash Investments 55,447 46,048 Hedging Collateral Deposits — 91,670 Receivables — Net of Allowance for Uncollectible Accounts of $ 36,295 and $ 40,228 , Respectively 160,601 361,626 Unbilled Revenue 16,622 30,075 Gas Stored Underground 32,509 32,364 Materials and Supplies -

All significant intercompany balances and transactions are eliminated. The Company uses proportionate consolidation when accounting for drilling arrangements related to oil and gas producing properties accounted for under the full cost method of accounting. The preparation of the consolidated financial statements in conformity with GAAP 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. Regulation The Company is subject to regulation by certain state and federal authorities. The Company has accounting policies which conform to GAAP, as applied to regulated enterprises, and are in accordance with the accounting requirements and ratemaking practices of the regulatory authorities. Reference is made to Note F — Regulatory Matters for further discussion. Allowance for Uncollectible Accounts The allowance for uncollectible accounts is the Company’s best estimate of the amount of probable credit losses in the existing accounts receivable. The allowance, the majority of which is in the Utility segment, is determined based on historical experience, the age of customer accounts, other specific information about customer accounts, and the economic and regulatory environment. Account balances have historically been written off against the allowance approximately twelve months after the account is final billed or when it is anticipated that the receivable will not be recovered. During 2022 and 2021, final billings were suppressed in the Utility segment as a result of state shut-off moratoriums arising from the COVID-19 pandemic. Those moratoriums were lifted in 2022 which allowed for the resumption of final billings during 2022, thereby resulting in higher amounts being written off in 2023. Activity in the allowance for uncollectible accounts are as follows: Year Ended September 30 2023 2022 2021 (Thousands) Balance at Beginning of Year $ 40,228 $ 31,639 $ 22,810 Additions Charged to Costs and Expenses 14,482 13,209 14,940 Add: Discounts on Purchased Receivables 1,380 1,314 1,168 Deduct: Net Accounts Receivable Written-Off 19,795 5,934 7,279 Balance at End of Year $ 36,295 $ 40,228 $ 31,639 Regulatory Mechanisms The Company’s rate schedules in the Utility segment contain clauses that permit adjustment of revenues to reflect price changes from the cost of purchased gas included in base rates. Differences between amounts currently recoverable and actual adjustment clause revenues, as well as other price changes and pipeline and storage company refunds not yet includable in adjustment clause rates, are deferred and accounted for as either unrecovered purchased gas costs or amounts payable to customers. Such amounts are generally recovered from (or passed back to) customers during the following fiscal year. -70- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) Estimated refund liabilities to ratepayers represent management’s current estimate of such refunds. Reference is made to Note F — Regulatory Matters for further discussion. The impact of weather on revenues in the Utility segment’s New York rate jurisdiction is tempered by a WNC, which covers the eight-month period from October through May. The WNC is designed to adjust the rates of retail customers to reflect the impact of deviations from normal weather. Weather that is warmer than normal results in a surcharge being added to customers’ current bills, while weather that is colder than normal results in a refund being credited to customers’ current bills. On June 15, 2023, the PaPUC approved the Utility segment’s Pennsylvania rate jurisdiction’s use of a WNC as a five-year pilot program. The program is effective October 2023 and covers the eight-month period from October through May. Prior to October 2023, the Utility segment’s Pennsylvania rate jurisdiction did not have a WNC, causing weather variations to have a direct impact on the Pennsylvania rate jurisdiction’s revenues. The impact of weather normalized usage per customer account in the Utility segment’s New York rate jurisdiction is tempered by a revenue decoupling mechanism. The effect of the revenue decoupling mechanism is to render the Company financially indifferent to throughput decreases resulting from conservation. Weather normalized usage per account that exceeds the average weather normalized usage per customer account results in a refund being credited to customers’ bills. Weather normalized usage per account that is below the average weather normalized usage per account results in a surcharge being added to customers’ bills. The surcharge or credit is calculated over a twelve-month period ending March 31st, and applied to customer bills annually, beginning July 1st. In the Pipeline and Storage segment, the allowed rates that Supply Corporation and Empire bill their customers are based on a straight fixed-variable rate design, which allows recovery of all fixed costs, including return on equity and income taxes, through fixed monthly reservation charges. Because of this rate design, changes in throughput due to weather variations do not have a significant impact on the revenues of Supply Corporation or Empire. Asset Acquisition and Business Combination Accounting In accordance with authoritative guidance issued by the FASB that clarifies the definition of a business, when the Company executes an acquisition, it will perform an initial screening test as of the acquisition date that, if met, results in the conclusion that the set of activities and assets is not a business. If the initial screening test is not met, the Company evaluates whether the set is a business based on whether there are inputs and a substantive process in place. The definition of a business impacts whether the Company consolidates an acquisition under business combination guidance or asset acquisition guidance. When the Company acquires assets and liabilities deemed to be an asset acquisition, the fair value of the purchase consideration, including the transaction costs of the asset acquisition, is assumed to be equal to the fair value of the net assets acquired. The purchase consideration, including the transaction costs, is allocated to the individual assets and liabilities assumed based on their relative fair values. Transaction costs associated with asset acquisitions are capitalized as part of the costs of the group of assets acquired. When the Company acquires assets and liabilities deemed to be a business combination, the acquisition method is applied. Goodwill is measured as the fair value of the consideration transferred less the net recognized fair value of the identifiable assets acquired and the liabilities assumed, all measured at the acquisition date. Transaction costs that the Company incurs in connection with a business combination, such as finders’ fees, legal fees, due diligence fees and other professional and consulting fees are expensed as incurred. Property, Plant and Equipment In the Company’s Exploration and Production segment, oil and gas property acquisition, exploration and development costs are capitalized under the full cost method of accounting. Under this methodology, all costs -71- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) associated with property acquisition, exploration and development activities are capitalized, including internal costs directly identified with acquisition, exploration and development activities. The internal costs that are capitalized do not include any costs related to production, general corporate overhead, or similar activities. The Company does not recognize any gain or loss on the sale or other disposition of oil and gas properties unless the gain or loss would significantly alter the relationship between capitalized costs and proved reserves of oil and gas attributable to a cost center. The Company's capitalized costs relating to oil and gas producing activities, net of accumulated depreciation, depletion and amortization, were $ 2.4 billion and $ 1.9 billion at September 30, 2023 and 2022, respectively. For further discussion of capitalized costs, refer to Note N — Supplementary Information for Oil and Gas Producing Activities. Capitalized costs are subject to the SEC full cost ceiling test. The ceiling test, which is performed each quarter, determines a limit, or ceiling, on the amount of property acquisition, exploration and development costs that can be capitalized. The ceiling under this test represents (a) the present value of estimated future net cash flows, excluding future cash outflows associated with settling asset retirement obligations that have been accrued on the balance sheet, using a discount factor of 10 %, which is computed by applying prices of oil and gas (as adjusted for hedging) to estimated future production of proved oil and gas reserves as of the date of the latest balance sheet, less estimated future expenditures, plus (b) the cost of unproved properties not being depleted, less (c) income tax effects related to the differences between the book and tax basis of the properties. The gas and oil prices used to calculate the full cost ceiling are based on an unweighted arithmetic average of the first day of the month oil and gas prices for each month within the twelve-month period prior to the end of the reporting period. If capitalized costs, net of accumulated depreciation, depletion and amortization and related deferred income taxes, exceed the ceiling at the end of any quarter, a permanent non-cash impairment is required to be charged to earnings in that quarter. At September 30, 2023, the ceiling exceeded the book value of the oil and gas properties by approximately $ 794.7 million. In adjusting estimated future net cash flows for hedging under the ceiling test at September 30, 2023, 2022 and 2021, estimated future net cash flows were increased by $ 38.8 million, decreased by $ 1.0 billion and decreased by $ 76.1 million, respectively. The principal assets of the Utility, Pipeline and Storage and Gathering segments, consisting primarily of gas distribution pipelines, transmission pipelines, storage facilities, gathering lines and compressor stations, are recorded at historical cost. There were no indications of any impairments to property, plant and equipment in the Utility, Pipeline and Storage and Gathering segments at September 30, 2023. Maintenance and repairs of property and replacements of minor items of property are charged directly to maintenance expense. The original cost of the regulated subsidiaries’ property, plant and equipment retired, and the cost of removal less salvage, are charged to accumulated depreciation. Depreciation, Depletion and Amortization For oil and gas properties, depreciation, depletion and amortization is computed based on quantities produced in relation to proved reserves using the units of production method. The cost of unproved oil and gas properties is excluded from this computation. Depreciation, depletion and amortization expense for oil and gas properties was $ 235.7 million, $ 202.4 million and $ 177.1 million for the years ended September 30, 2023, 2022 and 2021, respectively. For all other property, plant and equipment, depreciation and amortization is computed using the straight-line method in amounts sufficient to recover costs over the estimated useful lives of property in service. The following is a summary of depreciable plant by segment: -72- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) As of September 30 2023 2022 (Thousands) Exploration and Production $ 6,741,095 $ 6,088,476 Pipeline and Storage 2,803,690 2,747,948 Gathering 1,032,969 971,665 Utility 2,507,465 2,411,707 All Other and Corporate 15,787 13,712 $ 13,101,006 $ 12,233,508 Average depreciation, depletion and amortization rates are as follows: Year Ended September 30 2023 2022 2021 Exploration and Production, per Mcfe(1) $ 0.65 $ 0.59 $ 0.56 Pipeline and Storage 2.6 % 2.7 % 2.6 % Gathering 3.6 % 3.6 % 3.6 % Utility 2.7 % 2.7 % 2.7 % All Other and Corporate 2.9 % 1.4 % 3.4 % (1) Amounts include depletion of oil and gas producing properties as well as depreciation of fixed assets. As disclosed in Note N — Supplementary Information for Oil and Gas Producing Activities, depletion of oil and gas producing properties amounted to $ 0.63 , $ 0.57 and $ 0.54 per Mcfe of production in 2023, 2022 and 2021, respectively. Goodwill The Company has recognized goodwill of $ 5.5 million as of September 30, 2023 and 2022 on its Consolidated Balance Sheets related to the Company’s acquisition of Empire in 2003. The Company accounts for goodwill in accordance with the current authoritative guidance, which requires the Company to test goodwill for impairment annually. At September 30, 2023, 2022 and 2021, the fair value of Empire was greater than its book value. As such, the goodwill was not considered impaired at those dates. Going back to the origination of the goodwill in 2003, the Company has never recorded an impairment of its goodwill balance. Financial Instruments The Company uses a variety of derivative financial instruments to manage a portion of the market risk associated with fluctuations in the price of natural gas and to manage a portion of the risk of currency fluctuations associated with transportation costs denominated in Canadian currency. These instruments include natural gas price swap agreements and no cost collars and foreign currency forward contracts. The Company accounts for these instruments as cash flow hedges for which the fair value of the instrument is recognized on the Consolidated Balance Sheets as either an asset or a liability labeled Fair Value of Derivative Financial Instruments. Reference is made to Note I — Fair Value Measurements for further discussion concerning the fair value of derivative financial instruments. For cash flow hedges, the offset to the asset or liability that is recorded is a gain or loss recorded in accumulated other comprehensive income (loss) on the Consolidated Balance Sheets. The gain or loss recorded in accumulated other comprehensive income (loss) remains there until the hedged transaction occurs, at which point the gains or losses are reclassified to operating revenues on the Consolidated Statements of Income. Reference is made to Note J — Financial Instruments for further discussion concerning cash flow hedges. -73- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) Accumulated Other Comprehensive Loss The components of Accumulated Other Comprehensive Loss and changes for the years ended September 30, 2023 and 2022, net of related tax effects, are as follows (amounts in parentheses indicate debits) (in thousands): Gains and Losses on Derivative Financial Instruments Funded Status of the Pension and Other Post-Retirement Benefit Plans Total Year Ended September 30, 2023 Balance at October 1, 2022 $ ( 572,163 ) $ ( 53,570 ) $ ( 625,733 ) Other Comprehensive Gains and Losses Before Reclassifications 493,936 ( 7,376 ) 486,560 Amounts Reclassified From Other Comprehensive Loss 82,850 1,263 84,113 Balance at September 30, 2023 $ 4,623 $ ( 59,683 ) $ ( 55,060 ) Year Ended September 30, 2022 Balance at October 1, 2021 $ ( 449,962 ) $ ( 63,635 ) $ ( 513,597 ) Other Comprehensive Gains and Losses Before Reclassifications ( 763,223 ) 7,392 ( 755,831 ) Amounts Reclassified From Other Comprehensive Loss 641,022 8,480 649,502 Other Post-Retirement Adjustment for Regulatory Proceeding — ( 5,807 ) ( 5,807 ) Balance at September 30, 2022 $ ( 572,163 ) $ ( 53,570 ) $ ( 625,733 ) The amounts included in accumulated other comprehensive loss related to the funded status of the Company’s pension and other post-retirement benefit plans consist of prior service costs and accumulated losses. The total amount for prior service cost was $ 0.4 million at both September 30, 2023 and 2022. The total amount for accumulated losses was $ 59.3 million and $ 53.2 million at September 30, 2023 and 2022, respectively. During the quarter ended March 31, 2022, the PaPUC concluded a regulatory proceeding that addressed the recovery of OPEB expenses in Distribution Corporation's Pennsylvania service territory. As a result of that proceeding, Distribution Corporation discontinued regulatory accounting for OPEB expenses in Pennsylvania and a regulatory deferral of $ 7.4 million ($ 5.8 million after tax) related to the funded status of Distribution Corporation’s other post-retirement benefit plans in Pennsylvania was reclassified to accumulated other comprehensive loss. -74- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) Reclassifications Out of Accumulated Other Comprehensive Loss The details about the reclassification adjustments out of accumulated other comprehensive loss for the years ended September 30, 2023 and 2022 are as follows (amounts in parentheses indicate debits to the income statement) (in thousands): Details About Accumulated Other Comprehensive Loss Components Amount of Gain or (Loss) Reclassified from Accumulated Other Comprehensive Loss for the Year Ended September 30, Affected Line Item in the Statement Where Net Income is Presented 2023 2022 Gains (Losses) on Derivative Financial Instrument Cash Flow Hedges: Commodity Contracts $ ( 88,015 ) $ ( 882,594 ) Operating Revenues Foreign Currency Contracts ( 641 ) 13 Operating Revenues Amortization of Prior Year Funded Status of the Pension and Other Post-Retirement Benefit Plans: Prior Service Cost ( 82 ) ( 103 ) (1) Net Actuarial Loss ( 1,592 ) ( 10,951 ) (1) ( 90,330 ) ( 893,635 ) Total Before Income Tax 6,217 244,133 Income Tax Expense $ ( 84,113 ) $ ( 649,502 ) Net of Tax (1) These accumulated other comprehensive income (loss) components are included in the computation of net periodic benefit cost. Refer to Note K — Retirement Plan and Other Post-Retirement Benefits for additional details. Gas Stored Underground In the Utility segment, gas stored underground in the amount of $ 32.4 million is carried at lower of cost or net realizable value, on a LIFO method. Based upon the average price of spot market gas purchased in September 2023, including transportation costs, the current cost of replacing this inventory of gas stored underground exceeded the amount stated on a LIFO basis by approximately $ 3.7 million at September 30, 2023. Unamortized Debt Expense Costs associated with the reacquisition of debt related to rate-regulated subsidiaries are deferred and amortized over the remaining life of the issue or the life of the replacement debt in order to match regulatory treatment. At September 30, 2023, the remaining weighted average amortization period for such costs was approximately 4 years. Income Taxes The Company and its subsidiaries file a consolidated federal income tax return. State tax returns are filed on a combined or separate basis depending on the applicable laws in the jurisdictions where tax returns are filed. The Company follows the asset and liability approach in accounting for income taxes, which requires the recognition of deferred income taxes for the expected future tax consequences of net operating losses, credits and temporary differences between the financial statement carrying amounts and the tax basis of assets and liabilities. A valuation allowance is provided on deferred tax assets if it is determined, within each taxing jurisdiction, that it is more likely than not that the asset will not be realized. -75- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) The Company reports a liability or a reduction of deferred tax assets for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return. When applicable, the Company recognizes interest relating to uncertain tax positions in Other Interest Expense and penalties in Other Income (Deductions). Consolidated Statement of Cash Flows The components, as reported on the Company's Consolidated Balance Sheets, of the total cash, cash equivalents, and restricted cash presented on the Statement of Cash Flows are as follows (in thousands): Year Ended September 30 2023 2022 2021 2020 Cash and Temporary Cash Investments $ 55,447 $ 46,048 $ 31,528 $ 20,541 Hedging Collateral Deposits — 91,670 88,610 — Cash, Cash Equivalents, and Restricted Cash $ 55,447 $ 137,718 $ 120,138 $ 20,541 The Company considers all highly liquid debt instruments purchased with a maturity date of generally three months or less to be cash equivalents. The Company’s restricted cash is composed entirely of amounts reported as Hedging Collateral Deposits on the Consolidated Balance Sheets. Hedging Collateral Deposits is an account title for cash held in margin accounts funded by the Company to serve as collateral for derivative financial instruments in an unrealized loss position. In accordance with its accounting policy, the Company does not offset hedging collateral deposits paid or received against related derivative financial instruments liability or asset balances. Other Current Assets The components of the Company’s Other Current Assets are as follows: Year Ended September 30 2023 2022 (Thousands) Prepayments $ 18,966 $ 17,757 Prepaid Property and Other Taxes 14,186 14,321 Federal Income Taxes Receivable 14,602 — State Income Taxes Receivable 16,133 5,933 Regulatory Assets 36,373 21,358 $ 100,260 $ 59,369 Other Accruals and Current Liabilities The components of the Company’s Other Accruals and Current Liabilities are as follows: Year Ended September 30 2023 2022 (Thousands) Accrued Capital Expenditures $ 43,323 $ 64,720 Regulatory Liabilities 38,105 31,293 Liability for Royalty and Working Interests 17,679 86,206 Non-Qualified Benefit Plan Liability 13,052 17,474 Other 48,815 57,634 $ 160,974 $ 257,327 -76- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) Customer Advances The Company, primarily in its Utility segment, has balanced billing programs whereby customers pay their estimated annual usage in equal installments over a twelve-month period. Monthly payments under the balanced billing programs are typically higher than current month usage during the summer months. During the winter months, monthly payments under the balanced billing programs are typically lower than current month usage. At September 30, 2023 and 2022, customers in the balanced billing programs had advanced excess funds of $ 21.0 million and $ 26.1 million, respectively. Customer Security Deposits The Company, primarily in its Utility and Pipeline and Storage segments, oftentimes requires security deposits from marketers, producers, pipeline companies, and commercial and industrial customers before providing services to such customers. At September 30, 2023 and 2022, the Company had received customer security deposits amounting to $ 28.8 million and $ 24.3 million, respectively. Earnings Per Common Share Basic earnings per common share is computed by dividing income or loss by the weighted average number of common shares outstanding for the period. Diluted earnings per common share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock. For purposes of determining earnings per common share, the potentially dilutive securities the Company had outstanding during fiscal 2023, 2022 and/or 2021 were SARs, restricted stock units and performance shares. For the years ended September 30, 2023 and September 30, 2022, the diluted weighted average shares outstanding shown on the Consolidated Statements of Income reflects the potential dilution as a result of these securities as determined using the Treasury Stock Method. SARs, restricted stock units and performance shares that are antidilutive are excluded from the calculation of diluted earnings per common share. There were 3,888 securities, 2,858 securities and 320,222 securities excluded as being antidilutive for the years ended September 30, 2023, 2022 and 2021, respectively. Stock-Based Compensation The Company has various stock award plans which provide or provided for the issuance of one or more of the following to key employees: SARs, incentive stock options, nonqualified stock options, restricted stock, restricted stock units, performance units or performance shares. The Company follows authoritative guidance which requires the measurement and recognition of compensation cost at fair value for all share-based payments. SARs under all plans have exercise prices equal to the average market price of Company common stock on the date of grant, and generally no SAR is exercisable less than one year or more than ten years after the date of each grant. The Company chose the Black-Scholes-Merton closed form model to calculate the compensation expense associated with SARs. For all Company stock awards, forfeitures are recognized as they occur. Restricted stock units are subject to restrictions on vesting and transferability. Restricted stock units represent the right to receive shares of common stock of the Company (or the equivalent value in cash or a combination of cash and shares of common stock of the Company, as determined by the Company) at the end of a specified time period. The restricted stock units do not entitle the participants to dividend and voting rights. The fair value at the date of grant of the restricted stock units (represented by the market value of Company common stock on the date of the award) must be reduced by the present value of forgone dividends over the vesting term of the award. The fair value of restricted stock units on the date of award is recorded as compensation expense over the vesting period. Performance shares are an award constituting units denominated in common stock of the Company, the number of which may be adjusted over a performance cycle based upon the extent to which performance goals have been satisfied. Earned performance shares may be distributed in the form of shares of common stock of -77- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) the Company, an equivalent value in cash or a combination of cash and shares of common stock of the Company, as determined by the Company. The performance shares do not entitle the participant to receive dividends during the vesting period. For performance shares based on a return on capital goal and greenhouse gas emissions reductions goal, the fair value at the date of grant of the performance shares is determined by multiplying the expected number of performance shares to be issued by the market value of Company common stock on the date of grant reduced by the present value of forgone dividends. For performance shares based on a total shareholder return goal, the Company uses the Monte Carlo simulation technique to estimate the fair value price at the date of grant. Refer to Note H — Capitalization and Short-Term Borrowings under the heading “Stock Award Plans” for additional disclosures related to stock-based compensation awards for all plans. Note B — Asset Acquisitions and Divestitures On June 1, 2023, the Company completed its acquisition of certain upstream assets located primarily in Tioga County, Pennsylvania from SWN Production Company, LLC (“SWN”) for total consideration of $ 124.8 million. The purchase price, which reflects an effective date of January 1, 2023, was reduced for production revenues less expenses that were retained by SWN from the effective date to the closing date. As part of the transaction, the Company acquired approximately 34,000 net acres in an area that is contiguous with existing Company-owned upstream assets. This transaction was accounted for as an asset acquisition, and, as such, the purchase price was allocated to property, plant and equipment. The following is a summary of the asset acquisition in thousands: Purchase Price $ 124,178 Transaction Costs 580 Total Consideration $ 124,758 On June 30, 2022, the Company completed the sale of Seneca’s California assets, all of which were in the Exploration and Production segment, to Sentinel Peak Resources California LLC for a total sale price of $ 253.5 million, consisting of $ 240.9 million in cash and contingent consideration valued at $ 12.6 million at closing. The Company pursued this sale given the strong commodity price environment and the Company’s strategic focus in the Appalachian Basin. Under the terms of the purchase and sale agreement, the Company can receive up to three annual contingent payments between calendar year 2023 and calendar year 2025, not to exceed $ 10 million per year, with the amount of each annual payment calculated as $ 1.0 million for each $ 1 per barrel that the ICE Brent Average for each calendar year exceeds $ 95 per barrel up to $ 105 per barrel. The sale price, which reflected an effective date of April 1, 2022, was reduced for production revenues less expenses that were retained by Seneca from the effective date to the closing date. Under the full cost method of accounting for oil and natural gas properties, $ 220.7 million of the sale price at closing was accounted for as reduction of capitalized costs since the disposition did not alter the relationship between capitalized costs and proved reserves of oil and gas attributable to the cost center. The remainder of the sale price ($ 32.8 million) was applied against assets that are not subject to the full cost method of accounting, with the Company recognizing a gain of $ 12.7 million on the sale of such assets. The majority of this gain related to the sale of emission allowances. The Company also eliminated the asset retirement obligation associated with Seneca’s California oil and gas assets. This obligation amounted to $ 50.1 million and was accounted for as a reduction of capitalized costs under the full cost method of accounting. On December 10, 2020, the Company completed the sale of substantially all timber properties in Pennsylvania to Lyme Emporium Highlands III LLC and Lyme Allegheny Land Company II LLC for net proceeds of $ 104.6 million. These assets were a component of the Company’s All Other category and did not have a major impact on the Company’s operations or financial results. After purchase price adjustments and transaction costs, a gain of $ 51.1 million was recognized on the sale of these assets. Since the sale did not -78- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) represent a strategic shift in focus for the Company, the financial results associated with operating these assets as well as the gain on sale have not been reported as discontinued operations. The sale completed the financing of a July 31, 2020 acquisition of certain upstream assets and midstream gathering assets in Pennsylvania. Note C — Revenue from Contracts with Customers The following tables provide a disaggregation of the Company's revenues for the years ended September 30, 2023 and 2022, presented by type of service from each reportable segment.

The Company also records revenue related to alternative revenue programs in its Utility segment. Revenue related to derivative financial instruments and alternative revenue programs are excluded from the scope of the authoritative guidance regarding revenue recognition since they are accounted for under other existing accounting guidance. Exploration and Production Segment Revenue The Company’s Exploration and Production segment records revenue from the sale of the natural gas and oil that it produces and natural gas liquids (NGLs) processed based on entitlement, which means that revenue is recorded based on the actual amount of natural gas or oil that is delivered to a pipeline, or upon pick-up in the case of NGLs, and the Company’s ownership interest. Prior to the completion of the sale of the Company’s California assets on June 30, 2022, natural gas production occurred primarily in the Appalachian region of the United States and crude oil production occurred primarily in the West Coast region of the United States. Subsequent to June 30, 2022, substantially all Exploration and Production segment production consists of natural gas production from the Appalachian region of the United States. If a production imbalance occurs between what was supposed to be delivered to a pipeline and what was actually produced and delivered, the Company accrues the difference as an imbalance. The sales contracts generally require the Company to deliver a specific quantity of a commodity per day for a specific number of days at a price that is either fixed or variable and considers the delivery of each unit (MMBtu or Bbl) to be a separate performance obligation that is satisfied upon delivery. The transaction price for the sale of natural gas, oil and NGLs is contractually agreed upon based on prevailing market pricing (primarily tied to a market index with certain adjustments based on factors such as delivery location and prevailing supply and demand conditions) or fixed pricing. The Company allocates the transaction price to each performance obligation on the basis of the relative standalone selling price of each distinct unit sold. Revenue is recognized at a point in time when the transfer of the commodity occurs at the delivery point per the contract. The amount billable, as determined by the contracted quantity and price, indicates the value to the customer, and is used for revenue recognition purposes by the Exploration and Production segment as specified by the “invoice practical expedient” (the amount that the Exploration and Production segment has the right to invoice) under the authoritative guidance for revenue recognition. The contracts typically require payment within 30 days of the end of the calendar month in which the natural gas and oil is delivered, or picked up in the case of NGLs. The Company uses derivative financial instruments to manage commodity price risk in the Exploration and Production segment related to sales of the natural gas that it produces. Gains or losses on such derivative financial instruments are recorded as adjustments to revenue; however, they are not considered to be revenue from contracts with customers. Pipeline and Storage Segment Revenue The Company’s Pipeline and Storage segment records revenue for natural gas transportation and storage services in New York and Pennsylvania at tariff-based rates regulated by the FERC. Customers secure their own gas supply and the Pipeline and Storage segment provides transportation and/or storage services to move the customer-supplied gas to the intended location, including injections into or withdrawals from the storage field. This performance obligation is satisfied over time. The rate design for the Pipeline and Storage segment’s customers generally includes a combination of volumetric or commodity charges as well as monthly “fixed” charges (including charges commonly referred to as capacity charges, demand charges, or reservation charges). These types of fixed charges represent compensation for standing ready over the period of the month to deliver quantities of gas, regardless of whether the customer takes delivery of any quantity of gas. The performance obligation under these circumstances is satisfied based on the passage of time and meter reads, if applicable, which correlates to the period for which the charges are eligible to be invoiced. The amount -80- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) billable, as determined by the meter read and the “fixed” monthly charge, indicates the value to the customer, and is used for revenue recognition purposes by the Pipeline and Storage segment as specified by the “invoice practical expedient” (the amount that the Pipeline and Storage segment has the right to invoice) under the authoritative guidance for revenue recognition. Customers are billed after the end of each calendar month, with payment typically due by the 25th day of the month in which the invoice is received. The Company’s Pipeline and Storage segment expects to recognize the following revenue amounts in future periods related to “fixed” charges associated with remaining performance obligations for transportation and storage contracts: $ 210.7 million for fiscal 2024; $ 184.0 million for fiscal 2025; $ 148.3 million for fiscal 2026; $ 123.3 million for fiscal 2027; $ 107.5 million for fiscal 2028; and $ 581.0 million thereafter. Gathering Segment Revenue The Company’s Gathering segment provides gathering and processing services in the Appalachian region of Pennsylvania, primarily for Seneca. The Gathering segment’s primary performance obligation is to deliver gathered natural gas volumes from Seneca’s wells, and to a lesser extent, other producers' wells, into interstate pipelines at contractually agreed upon per unit rates. This obligation is satisfied over time. The performance obligation is satisfied based on the passage of time and meter reads, which correlates to the period for which the charges are eligible to be invoiced. The amount billable, as determined by the meter read and the contracted volumetric rate, indicates the value to the customer, and is used for revenue recognition purposes by the Gathering segment as specified by the “invoice practical expedient” (the amount that the Gathering segment has the right to invoice) under the authoritative guidance for revenue recognition. Customers are billed after the end of each calendar month, with payment typically due by the 10th day after the invoice is received. Utility Segment Revenue The Company’s Utility segment records revenue for natural gas sales and natural gas transportation services in western New York and northwestern Pennsylvania at tariff-based rates regulated by the NYPSC and the PaPUC, respectively. Natural gas sales and transportation services are provided largely to residential, commercial and industrial customers. The Utility segment’s performance obligation to its customers is to deliver natural gas, an obligation which is satisfied over time. This obligation generally remains in effect as long as the customer consumes the natural gas provided by the Utility segment. The Utility segment recognizes revenue when it satisfies its performance obligation by delivering natural gas to the customer. Natural gas is delivered and consumed by the customer simultaneously. The satisfaction of the performance obligation is measured by the turn of the meter dial. The amount billable, as determined by the meter read and the tariff-based rate, indicates the value to the customer, and is used for revenue recognition purposes by the Utility segment as specified by the “invoice practical expedient” (the amount that the Utility segment has the right to invoice) under the authoritative guidance for revenue recognition. Since the Utility segment bills its customers in cycles having billing dates that do not generally coincide with the end of a calendar month, a receivable is recorded for natural gas delivered but not yet billed to customers based on an estimate of the amount of natural gas delivered between the last meter reading date and the end of the accounting period. Such receivables are a component of Unbilled Revenue on the Consolidated Balance Sheets. The Utility segment’s tariffs allow customers to utilize budget billing. In this situation, since the amount billed may differ from the amount of natural gas delivered to the customer in any given month, revenue is recognized monthly based on the amount of natural gas consumed. The differential between the amount billed and the amount consumed is recorded as a component of Receivables or Customer Advances on the Consolidated Balance Sheets. All receivables or advances related to budget billing are settled within one year . Utility Segment Alternative Revenue Programs As indicated in the revenue table shown above, the Company’s Utility segment has alternative revenue programs that are excluded from the scope of the authoritative guidance regarding revenue recognition. The NYPSC has authorized alternative revenue programs that are designed to mitigate the impact that weather and -81- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) conservation have on margin. The NYPSC and PaPUC have also authorized additional alternative revenue programs that adjust billings for the effects of broad external factors or to compensate the Company for demand-side management initiatives. These alternative revenue programs primarily allow the Company and customer to share in variances from imputed margins due to migration of transportation customers, allow for adjustments to the gas cost recovery mechanism for fluctuations in uncollectible expenses associated with gas costs, and allow the Company to pass on to customers costs associated with customer energy efficiency programs. In general, revenue is adjusted monthly for these programs and is collected from or passed back to customers within 24 months of the annual reconciliation period. Note D — Leases The Company follows authoritative guidance regarding lease accounting, which requires entities that lease the use of property, plant and equipment to recognize on the balance sheet the assets and liabilities for the rights and obligations created by all leases, including leases classified as operating leases. The Company has elected to apply the following practical expedients provided in the authoritative guidance: 1. An election not to apply the recognition requirements in the new authoritative guidance to short-term leases (a lease that at commencement date has a lease term of one year or less); 2. A practical expedient that permits combining lease and non-lease components in a contract and accounting for the combination as a lease (elected by asset-class). Nature of Leases The Company primarily leases building space and drilling rigs, and on a limited basis, compressor equipment and other miscellaneous assets. The Company determines if an arrangement is a lease at the inception of the arrangement. To the extent that an arrangement represents a lease, the Company classifies that lease as an operating or a finance lease in accordance with the authoritative guidance. The Company did not have any material finance leases as of September 30, 2023 or September 30, 2022. Aside from a sublease of office space at the Company’s corporate headquarters, which terminated April 30, 2022, the Company does not have any material arrangements where the Company is the lessor. Buildings and Property The Company enters into building and property rental agreements with third parties for office space, certain field locations and other properties used in the Company’s operations. Building and property leases include the Company’s corporate headquarters in Williamsville, New York, and Exploration and Production segment offices in Houston, Texas, and Pittsburgh, Pennsylvania. The primary non-cancelable terms of the Company’s building and property leases range from one month to sixteen years . Most building leases include one or more options to renew, generally at the Company’s sole discretion, with renewal terms that can extend the lease terms from one year to eighteen years . Renewal options are included in the lease term if they are reasonably certain to be exercised. The agreements do not contain any material restrictive covenants. Drilling Rigs The Company enters into contracts for drilling rig services with third party contractors to support Seneca’s development activities in Pennsylvania. Seneca’s drilling rig arrangements are structured with a non-cancelable primary term of one year or less. Upon mutual agreement with the contractor, Seneca has the option to extend contracts with amended terms and conditions, including a renegotiated day rate fee. Drilling rig lease costs are capitalized as part of natural gas properties on the Consolidated Balance Sheet when incurred. -82- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) Compressor Equipment The Company enters into contracts for compressor services with third parties primarily to support its gathering system in Pennsylvania. The primary non-cancelable terms of the Company's compressor equipment leases range from 9 months to 5 years. Most compressor equipment leases include one or more options to renew or to continue past the primary term on a month-to-month basis, generally at the Company's sole discretion. Renewal options are included in the lease term if they are reasonably certain to be exercised. Significant Judgments Lease Identification The Company uses judgment when determining whether or not an arrangement is or contains a lease. A contract is or contains a lease if the contract conveys the right to use an explicitly or implicitly identified asset that is physically distinct and the Company has the right to control the use of the identified asset for a period of time. When determining right of control, the Company evaluates whether it directs the use of the asset and obtains substantially all of the economic benefits from the use of the asset. Discount Rate The Company uses a discount rate to calculate the present value of lease payments in order to determine lease classification and measurement of the lease asset and liability. In the absence of a rate of interest that is readily determinable in the contract, the Company estimates the incremental borrowing rate (IBR) for each lease. The IBR reflects the rate of interest that the Company would pay on the lease commencement date to borrow an amount equal to the lease payments on a collateralized basis over a similar term in similar economic environments. Firm Transportation and Storage Contracts The Company’s subsidiaries enter into long-term arrangements to both reserve firm transportation capacity on third party pipelines and provide firm transportation and storage services to third party shippers. The Company’s firm capacity contracts with third party shippers do not provide rights to use substantially all of the underlying pipeline or storage asset. As such, the Company has concluded that these arrangements are not leases under the authoritative guidance. Gas Leases The authoritative guidance does not apply to leases to explore for or use natural gas resources, including the right to explore for those resources and rights to use the land in which those resources are contained. As such, the Company has concluded that its gas exploration and production leases and gas storage leases are not leases under the authoritative guidance. -83- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) Amounts Recognized in the Financial Statements Operating lease costs, excluding those relating to drilling rig leases that are capitalized as part of oil and natural gas properties under the full cost method of accounting as well as certain equipment leases related to construction projects, are presented in Operations and Maintenance expense on the Consolidated Statement of Income. The following table summarizes the components of the Company’s total operating lease costs (in thousands): Year Ended September 30 2023 2022 Operating Lease Expense $ 7,484 $ 4,909 Variable Lease Expense(1) 507 462 Short-Term Lease Expense(2) 1,694 461 Sublease Income — ( 166 ) Total Lease Expense $ 9,685 $ 5,666 Lease Costs Recorded to Property, Plant and Equipment(3) $ 24,018 $ 19,839 (1) Variable lease payments that are not dependent on an index or rate are not included in the lease liability. (2) Short-term lease costs exclude expenses related to leases with a lease term of one month or less. (3) Lease costs relating to drilling rig leases that are capitalized as part of oil and natural gas properties under full cost pool accounting as well as certain equipment leases used on construction projects. Right-of-use assets and lease liabilities are recognized at the commencement date of a leasing arrangement based on the present value of lease payments over the lease term. The weighted average remaining lease term was 6.1 years and 6.0 years as of September 30, 2023 and 2022, respectively. The weighted average discount rate was 5.48 % and 3.92 % as of September 30, 2023 and 2022, respectively. The Company’s right-of-use operating lease assets are reflected as Deferred Charges on the Consolidated Balance Sheet. The corresponding operating lease liabilities are reflected in Other Accruals and Current Liabilities (current) and Other Liabilities (noncurrent). Short-term leases that have a lease term of one year or less are not recorded on the Consolidated Balance Sheet. The following amounts related to operating leases were recorded on the Company’s Consolidated Balance Sheet (in thousands): Year Ended September 30 2023 2022 Assets: Deferred Charges $ 39,664 $ 37,120 Liabilities: Other Accruals and Current Liabilities $ 9,969 $ 14,239 Other Liabilities $ 29,510 $ 22,881 Cash paid for lease liabilities, reported in cash provided by operating activities on the Company’s Consolidated Statement of Cash Flows, was $ 9.7 million and $ 5.7 million for the years ended September 30, 2023 and 2022, respectively. The Company did no t record any right-of-use assets in exchange for new lease liabilities during the years ended September 30, 2023 or 2022. -84- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) The following schedule of operating lease liability maturities summarizes the undiscounted lease payments owed by the Company to lessors pursuant to contractual agreements in effect as of September 30, 2023 (in thousands): At September 30, 2023 2024 $ 10,187 2025 8,791 2026 6,557 2027 5,809 2028 5,195 Thereafter 9,971 Total Lease Payments 46,510 Less: Interest ( 7,031 ) Total Lease Liability $ 39,479 Note E — Asset Retirement Obligations The Company accounts for asset retirement obligations in accordance with the authoritative guidance that requires entities to record the fair value of a liability for an asset retirement obligation in the period in which it is incurred. An asset retirement obligation is defined as a legal obligation associated with the retirement of a tangible long-lived asset in which the timing and/or method of settlement may or may not be conditional on a future event that may or may not be within the control of the Company. When the liability is initially recorded, the entity capitalizes the estimated cost of retiring the asset as part of the carrying amount of the related long-lived asset. Over time, the liability is adjusted to its present value each period and the capitalized cost is depreciated over the useful life of the related asset. The Company estimates the fair value of its asset retirement obligations based on the discounting of expected cash flows using various estimates, assumptions and judgments regarding certain factors such as the existence of a legal obligation for an asset retirement obligation; estimated amounts and timing of settlements; the credit-adjusted risk-free rate to be used; and inflation rates. Asset retirement obligations incurred in the current period were Level 3 fair value measurements as the inputs used to measure the fair value are unobservable. The Company has recorded an asset retirement obligation representing plugging and abandonment costs associated with the Exploration and Production segment’s natural gas wells and has capitalized such costs in property, plant and equipment (i.e. the full cost pool). During fiscal 2021, this segment’s Appalachian operations were required to implement additional water testing on a portion of its assets, which contributed to an increase in the asset retirement obligation. This increase is the primary component of the Revisions of Estimates amount for fiscal 2021 shown in the table below. In addition to the asset retirement obligation recorded in the Exploration and Production segment, the Company has recorded future asset retirement obligations associated with the plugging and abandonment of natural gas storage wells in the Pipeline and Storage segment and the removal of asbestos and asbestos-containing material in various facilities in the Utility and Pipeline and Storage segments. Asset retirement obligation costs related to storage tanks have been recorded in the Utility, Pipeline and Storage, and Gathering segments. The Company has also recorded asset retirement obligations for certain costs connected with the retirement of the distribution mains, services and other components of the pipeline system in the Utility segment, the transmission mains and other components in the pipeline system in the Pipeline and Storage segment, and the gathering lines and other components in the Gathering segment. The retirement costs within the distribution, transmission and gathering systems are primarily for the capping and purging of pipe, which are generally abandoned in place when retired, as well as for the clean-up of PCB contamination associated with the removal of certain pipe. -85- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) As discussed in Note B — Asset Acquisitions and Divestitures, on June 30, 2022, the Company completed the sale of Seneca’s California oil and gas assets to Sentinel Peak Resources California LLC. With the divestiture of these assets, the Company reduced its Asset Retirement Obligation at June 30, 2022 by $ 50.1 million. This reduction is reflected in Liabilities Settled in the table below. The following is a reconciliation of the change in the Company’s asset retirement obligations: Year Ended September 30 2023 2022 2021 (Thousands) Balance at Beginning of Year $ 161,545 $ 209,639 $ 192,228 Liabilities Incurred 3,313 2,401 7,035 Revisions of Estimates 6,728 10,700 14,509 Liabilities Settled ( 14,448 ) ( 71,171 ) ( 14,270 ) Accretion Expense 8,354 9,976 10,137 Balance at End of Year $ 165,492 $ 161,545 $ 209,639 Note F — Regulatory Matters Regulatory Assets and Liabilities The Company has recorded the following regulatory assets and liabilities: At September 30 2023 2022 (Thousands) Regulatory Assets(1): Pension Costs(2) (Note K) $ 20,459 $ 11,677 Post-Retirement Benefit Costs(2) (Note K) 2,536 6,814 Recoverable Future Taxes (Note G) 69,045 106,247 Environmental Site Remediation Costs(2) (Note L) — 3,646 Asset Retirement Obligations(2) (Note E) 19,384 18,517 Unamortized Debt Expense (Note A) 7,240 8,884 Other(3) 66,132 47,805 Total Regulatory Assets 184,796 203,590 Less: Amounts Included in Other Current Assets ( 36,373 ) ( 21,358 ) Total Long-Term Regulatory Assets $ 148,423 $ 182,232 -86- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) At September 30 2023 2022 (Thousands) Regulatory Liabilities: Cost of Removal Regulatory Liability $ 277,694 $ 259,947 Taxes Refundable to Customers (Note G) 268,562 362,098 Post-Retirement Benefit Costs(5) (Note K) 159,760 167,305 Pension Costs(4) (Note K) — 8,242 Amounts Payable to Customers (See Regulatory Mechanisms in Note A) 59,019 419 Environmental Site Remediation Costs(4) (Note L) 619 — Other(6) 43,167 44,549 Total Regulatory Liabilities 808,821 842,560 Less: Amounts included in Current and Accrued Liabilities ( 97,124 ) ( 31,712 ) Total Long-Term Regulatory Liabilities $ 711,697 $ 810,848 (1) The Company recovers the cost of its regulatory assets but generally does not earn a return on them. There are a few exceptions to this rule. For example, the Company does earn a return on Unrecovered Purchased Gas Costs and, in the New York jurisdiction of its Utility segment, earns a return, within certain parameters, on the excess of cumulative funding to the pension plan over the cumulative amount collected in rates. (2) Included in Other Regulatory Assets on the Consolidated Balance Sheets. (3) $ 36,373 and $ 21,358 are included in Other Current Assets on the Consolidated Balance Sheets at September 30, 2023 and 2022, respectively, since such amounts are expected to be recovered from ratepayers in the next 12 months. $ 29,759 and $ 26,447 are included in Other Regulatory Assets on the Consolidated Balance Sheets at September 30, 2023 and 2022, respectively. (4) Included in Other Regulatory Liabilities on the Consolidated Balance Sheets. (5) $ 5,800 is included in Other Accruals and Current Liabilities on the Consolidated Balance Sheets at both September 30, 2023 and 2022, since such amounts are expected to be passed back to ratepayers in the next 12 months. $ 153,960 and $ 161,505 are included in Other Regulatory Liabilities on the Consolidated Balance Sheets at September 30, 2023 and 2022, respectively. (6) $ 32,305 and $ 25,493 are included in Other Accruals and Current Liabilities on the Consolidated Balance Sheets at September 30, 2023 and 2022, respectively, since such amounts are expected to be passed back to ratepayers in the next 12 months. $ 10,862 and $ 19,056 are included in Other Regulatory Liabilities on the Consolidated Balance Sheets at September 30, 2023 and 2022, respectively. If for any reason the Company ceases to meet the criteria for application of regulatory accounting treatment for all or part of its operations, the regulatory assets and liabilities related to those portions ceasing to meet such criteria would be eliminated from the Consolidated Balance Sheets and included in income of the period in which the discontinuance of regulatory accounting treatment occurs. Cost of Removal Regulatory Liability In the Company’s Utility and Pipeline and Storage segments, costs of removing assets (i.e. asset retirement costs) are collected from customers through depreciation expense. These amounts are not a legal retirement obligation as discussed in Note E — Asset Retirement Obligations. Rather, they are classified as a regulatory liability in recognition of the fact that the Company has collected dollars from customers that will be used in the future to fund asset retirement costs. -87- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) New York Jurisdiction Distribution Corporation's current delivery rates in its New York jurisdiction were approved by the NYPSC in an order issued on April 20, 2017 with rates becoming effective May 1, 2017 ("2017 Rate Order"). The 2017 Rate Order provided for a return on equity of 8.7 % and directed the implementation of an earnings sharing mechanism to be in place beginning on April 1, 2018. On October 31, 2023, Distribution Corporation made a filing with the NYPSC seeking an increase of $ 88.8 million in its total annual operating revenues for the projected rate year ending September 30, 2025, with a proposed effective date of October 1, 2024 that includes the maximum suspension period permitted under the New York Public Service Law ("2023 Rate Filing"). The Company is also proposing, among other things, to continue its leak prone pipe replacement program and to implement a number of initiatives that will facilitate achievement of the emissions reduction goals of the Climate Leadership and Community Protection Act. The 2017 Rate Order authorized the Company to recover approximately $ 15 million annually for pension and OPEB expenses from customers. Because the Company’s future pension and OPEB costs were projected to be satisfied with existing funds held in reserve, in July 2022, Distribution Corporation made a filing with the NYPSC to effectuate a temporary pension and OPEB surcredit to customers to offset these amounts being collected in base rates effective October 1, 2022. On September 16, 2022, the NYPSC issued an order approving the filing. With the implementation of this surcredit, Distribution Corporation ceased funding the Retirement Plan and its VEBA trusts in its New York jurisdiction. The 2023 Rate Filing proposes to keep the rate recovery of pension and OPEB costs at zero in the rate year and reflect the $ 15 million of savings in new base delivery rates. On August 13, 2021, the NYPSC issued an order extending the date through which qualified pipeline replacement costs incurred by the Company can be recovered using the existing system modernization tracker for two years (until March 31, 2023). On December 9, 2022, the Company filed a petition with the NYPSC to effectuate a system improvement tracker through which qualified pipeline replacement costs through September 30, 2024 would be tracked and recovered, and to recover certain deferred costs associated with the existing system modernization tracker, effective April 1, 2023. The NYPSC approved the petition by order dated March 17, 2023 contingent on the Company not filing a base rate case that would result in new rates becoming effective prior to October 1, 2024. The 2023 Rate Filing proposes to stop accruing and collecting revenues under its current system modernization and system improvement trackers and shift those revenues into the Company’s new base delivery rates. In the absence of a multi-year rate plan settlement, the Company is requesting that it be allowed to reinstate a tracking mechanism similar to the existing system modernization tracker. Pennsylvania Jurisdiction Distribution Corporation’s delivery rates effective through July 31, 2023 in its Pennsylvania jurisdiction were approved by the PaPUC on November 30, 2006 as part of a settlement agreement that became effective January 1, 2007. On October 28, 2022, Distribution Corporation made a filing with the PaPUC seeking an increase in its annual base rate operating revenues of $ 28.1 million. A settlement involving all active parties to the proceeding was reached and filed with the PaPUC on April 13, 2023. The settlement provided for, among other things, an increase in Distribution Corporation’s annual base rate operating revenues of $ 23 million. The PaPUC approved the settlement in full, without modification or correction, on June 15, 2023 and new rates went into effect on August 1, 2023. Effective October 1, 2021, pursuant to a tariff supplement filed with the PaPUC, Distribution Corporation reduced base rates by $ 7.7 million in order to stop collecting OPEB expenses from customers. It also began to refund to customers overcollected OPEB expenses in the amount of $ 50.0 million. All matters with respect to this tariff supplement were finalized on February 24, 2022 with the PaPUC’s approval of an Administrative Law Judge’s Recommended Decision. Concurrent with that decision, the Company discontinued regulatory -88- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) accounting for OPEB expenses and recorded an $ 18.5 million adjustment during the quarter ended March 31, 2022 to reduce its regulatory liability for previously deferred OPEB income amounts through September 30, 2021 and to increase Other Income (Deductions) on the consolidated financial statements by a like amount. The Company also increased customer refunds of overcollected OPEB expenses from $ 50.0 million to $ 54.0 million. All refunds specified in the tariff supplement are being funded entirely by grantor trust assets held by the Company, most of which are included in a fixed income mutual fund that is a component of Other Investments on the Company’s Consolidated Balance Sheet. With the elimination of OPEB expenses in base rates, Distribution Corporation is no longer funding the grantor trust or its VEBA trusts in its Pennsylvania jurisdiction. FERC Jurisdiction Supply Corporation filed a NGA Section 4 rate case at FERC on July 31, 2023 proposing rate increases to be effective February 1, 2024. The proposed rates reflect an annual cost of service of $ 385.4 million, a rate base of $ 1.32 billion and a proposed cost of equity of 15.12 %. If the proposed rate increases finally approved at the end of the proceeding exceed the rates that were in effect at July 31, 2023, but are less than rates put into effect subject to refund on February 1, 2024, Supply Corporation would be required to refund the difference between the rates collected subject to refund and the final approved rates, with interest at the FERC-approved rate. If the rates approved at the end of the proceeding are lower than the rates in effect at July 31, 2023, such lower rates will become effective prospectively from the effective date provided by the applicable FERC order, and refunds with interest will be limited to the difference between the rates collected subject to refund and the rates in effect at July 31, 2023. Empire’s 2019 rate settlement provides that Empire must make a rate case filing no later than May 1, 2025. Note G — Income Taxes The components of federal and state income taxes included in the Consolidated Statements of Income are as follows: Year Ended September 30 2023 2022 2021 (Thousands) Current Income Taxes — Federal $ 11,744 $ — $ ( 10 ) State 1,386 12,214 8,699 Deferred Income Taxes — Federal 106,801 137,025 90,970 State 44,602 ( 32,610 ) 15,023 Total Income Taxes $ 164,533 $ 116,629 $ 114,682 On July 8, 2022, House Bill 1342 was signed into law in Pennsylvania. The law reduces the corporate income tax rate to 8.99 % for fiscal 2024. Starting with fiscal 2025, the rate is reduced by 0.5 % annually until it reaches 4.99 % for fiscal 2032. Under GAAP, the tax effects of a change in tax law must be recognized in the period in which the law is enacted. GAAP also requires deferred income tax assets and liabilities to be measured at the enacted tax rate expected to apply when temporary differences are to be realized or settled. During fiscal 2022, the Company's deferred income taxes were initially re-measured based upon the new tax rates. For the Company's non-rate regulated activities, the change in deferred income taxes was $ 28.4 million as of the enactment date and was recorded as a reduction to income tax expense. For the Company's rate regulated activities, the reduction in deferred income taxes of $ 37.2 million was recorded as a decrease to Recoverable Future Taxes of $ 19.8 million and an increase to Taxes Refundable to Customers of $ 17.4 million -89- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) during the quarter ended September 30, 2022. As the rate reduction occurs through fiscal 2032, an annual re-measurement will be made. This amount is reflected in State Income Taxes. On August 16, 2022, the "Inflation Reduction Act" (IRA) was signed into law. The IRA, among other things, includes provisions to expand energy incentives and impose a corporate minimum tax. The provisions of the IRA did not have a material impact on the accompanying financial statements, although some of the provisions may be applicable in future years. Total income taxes as reported differ from the amounts that were computed by applying the federal income tax rate to income before income taxes. The following is a reconciliation of this difference: Year Ended September 30 2023 2022 2021 (Thousands) U.S. Income Before Income Taxes $ 641,399 $ 682,650 $ 478,329 Income Tax Expense, Computed at U.S. Federal Statutory Rate of 21 % $ 134,694 $ 143,357 $ 100,449 State Valuation Allowance (1) — ( 24,850 ) ( 5,560 ) State Income Taxes (2) 36,331 8,736 24,300 Amortization of Excess Deferred Federal Income Taxes ( 6,053 ) ( 5,184 ) ( 5,215 ) Plant Flow Through Items ( 2,856 ) ( 814 ) ( 1,503 ) Stock Compensation 957 820 2,239 Federal Tax Credits ( 6 ) ( 5,701 ) ( 310 ) Miscellaneous 1,466 265 282 Total Income Taxes $ 164,533 $ 116,629 $ 114,682 (1) During fiscal 2022, the valuation allowance recorded against certain state deferred tax assets was removed. See discussion below. (2) The state income tax expense shown above includes adjustments to the estimated state effective tax rates utilized in the calculation of deferred income taxes, including the Pennsylvania rate change discussed above. Significant components of the Company’s deferred tax liabilities and assets were as follows: At September 30 2023 2022 (Thousands) Deferred Tax Liabilities: Unrealized Hedging Gains $ 3,385 $ — Property, Plant and Equipment 1,178,893 954,757 Pension and Other Post-Retirement Benefit Costs 44,358 30,132 Other 21,470 48,893 Total Deferred Tax Liabilities 1,248,106 1,033,782 Deferred Tax Assets: Unrealized Hedging Losses — ( 215,187 ) Tax Loss and Credit Carryforwards ( 33,744 ) ( 50,686 ) Pension and Other Post-Retirement Benefit Costs ( 41,843 ) ( 37,250 ) Other ( 48,349 ) ( 32,430 ) Total Deferred Tax Assets ( 123,936 ) ( 335,553 ) Total Net Deferred Income Taxes $ 1,124,170 $ 698,229 -90- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) The following is a summary of changes in valuation allowances for deferred tax assets: Year Ended September 30 2023 2022 2021 (Thousands) Balance at Beginning of Year $ — $ 57,645 $ 63,205 Additions — — — Deductions — 57,645 5,560 Balance at End of Year $ — $ — $ 57,645 A valuation allowance for deferred tax assets, including net operating losses and tax credits, is recognized when it is more likely than not that some or all of the benefit from the deferred tax assets will not be realized. The Company, at each reporting date, assesses the realizability of its deferred tax assets, including factors such as future taxable income, reversal of existing temporary differences, and tax planning strategies. The Company considers both positive and negative evidence related to the likelihood of the realization of the deferred tax assets. On June 30, 2022, the Company completed the sale of Seneca's California oil and gas assets to Sentinel Peak Resources California, LLC. As a result of the sale of the California oil and gas assets, the remaining deferred tax assets and valuation allowance of approximately $ 27.2 million related to the California net operating loss and tax credit carryforwards were written off, as the Company determined that there was a remote possibility for use as the Company no longer has California operations. During the quarter ended September 30, 2022, the valuation allowance was adjusted because of the Pennsylvania corporate income tax rate change remeasurement described above and for current activity, for a cumulative adjustment of $ 5.5 million. In addition, the Company determined there was sufficient positive evidence, despite a prior history of subsidiary tax losses, to conclude that it was more likely than not that the remaining state deferred tax assets would be realized. The conclusion was primarily related to the use of net operating losses in Pennsylvania in 2022 due to sustained strong operating results as well as the expectation for future forecasted earnings in Pennsylvania. The sale of California assets also resulted in higher apportionment of income to Pennsylvania on a prospective basis, which further supported realization of existing Pennsylvania net operating loss deferred tax assets. Accordingly, as of September 30, 2022, the Company reversed the remaining valuation allowance and recognized an income tax benefit of approximately $ 24.9 million. Regulatory liabilities representing the reduction of previously recorded deferred income taxes associated with rate-regulated activities that are expected to be refundable to customers amounted to $ 268.6 million and $ 362.1 million at September 30, 2023 and 2022, respectively. Also, regulatory assets representing future amounts collectible from customers, corresponding to additional deferred income taxes not previously recorded because of ratemaking practices, amounted to $ 69.0 million and $ 106.2 million at September 30, 2023 and 2022, respectively. The primary change in these was due to Distribution Corporation's rate settlement in Pennsylvania. For further discussion of Distribution Corporation rate matters, refer to Note F — Regulatory Matters. The Company is in the Compliance Maintenance Phase of the IRS Compliance Assurance Process (“CAP”) for fiscal 2023. The CAP program is intended for taxpayers with a low risk of non-compliance who are cooperative and transparent with few, if any, material issues that require resolution. The federal statute of limitations remains open for fiscal 2020 and later years. The Company is also subject to various routine state income tax examinations. The Company’s principal subsidiaries have state statutes of limitations that generally expire between three to four years from the date of filing of the income tax return. Net operating losses being carried forward from prior years remain subject to examination on a future return until they are utilized, upon which time the statute of limitation begins. The Company has no unrecognized tax benefits as of September 30, 2023, 2022, or 2021. -91- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) During fiscal 2009, preliminary consent was received from the IRS National Office approving the Company’s application to change its tax method of accounting for certain capitalized costs relating to its utility property, subject to final guidance. The IRS released guidance on April 14, 2023, providing a natural gas transmission and distribution property safe harbor method of accounting (“NGSH method”) that taxpayers may use to determine whether expenses to repair, maintain, replace, or improve natural gas transmission and distribution property must be capitalized or be allowable as deductions for repairs. The Company is planning to elect this change in tax accounting method with its consolidated tax return filing in the upcoming year and has reflected an estimate in the September 30, 2023 financial statements of what is intended to be treated as a repair for tax purposes rather than being capitalized. That estimate, which amounted to $ 99.5 million, has been recorded in Income Tax Expense. Tax carryforwards available, prior to valuation allowance, at September 30, 2023, were as follows: Jurisdiction Tax Attribute Amount (Thousands) Expires Pennsylvania Net Operating Loss $ 404,403 2031-2043 Federal General Business Credits $ 1,819 2042 -92- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) Note H — Capitalization and Short-Term Borrowings Summary of Changes in Common Stock Equity Common Stock Paid In Capital Earnings Reinvested in the Business Accumulated Other Comprehensive Income (Loss) Shares Amount (Thousands, except per share amounts) Balance at September 30, 2020 90,955 $ 90,955 $ 1,004,158 $ 991,630 $ ( 114,757 ) Net Income Available for Common Stock 363,647 Dividends Declared on Common Stock ($ 1.80 Per Share) ( 164,102 ) Other Comprehensive Loss, Net of Tax ( 398,840 ) Share-Based Payment Expense(1) 15,297 Common Stock Issued (Repurchased) Under Stock and Benefit Plans 227 227 ( 2,009 ) Balance at September 30, 2021 91,182 91,182 1,017,446 1,191,175 ( 513,597 ) Net Income Available for Common Stock 566,021 Dividends Declared on Common Stock ($ 1.86 Per Share) ( 170,111 ) Other Comprehensive Loss, Net of Tax ( 112,136 ) Share-Based Payment Expense(1) 17,699 Common Stock Issued (Repurchased) Under Stock and Benefit Plans 296 296 ( 8,079 ) Balance at September 30, 2022 91,478 91,478 1,027,066 1,587,085 ( 625,733 ) Net Income Available for Common Stock 476,866 Dividends Declared on Common Stock ($ 1.94 Per Share) ( 178,095 ) Other Comprehensive Income, Net of Tax 570,673 Share-Based Payment Expense(1) 18,746 Common Stock Issued (Repurchased) Under Stock and Benefit Plans 341 341 ( 5,051 ) Balance at September 30, 2023 91,819 $ 91,819 $ 1,040,761 $ 1,885,856 (2) $ ( 55,060 ) (1) Paid in Capital includes compensation costs associated with performance shares and/or restricted stock awards.

(2) The availability of consolidated earnings reinvested in the business for dividends payable in cash is limited under terms of the indentures covering long-term debt. At September 30, 2023, $ 1.7 billion of accumulated earnings was free of such limitations. Common Stock The Company has various plans which allow shareholders, employees and others to purchase shares of the Company common stock. The National Fuel Gas Company Direct Stock Purchase and Dividend Reinvestment Plan allows shareholders to reinvest cash dividends and make cash investments in the Company’s common stock and provides investors the opportunity to acquire shares of the Company common stock without the payment of any brokerage commissions in connection with such acquisitions. The 401(k) Plans allow employees the opportunity to invest in the Company common stock, in addition to a variety of other investment alternatives. Generally, at the discretion of the Company, shares purchased under these plans are either original -93- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) issue shares purchased directly from the Company or shares purchased on the open market by an independent agent. During 2023, the Company did no t issue any original issue shares of common stock for the Direct Stock Purchase and Dividend Reinvestment Plan or the Company's 401(k) plans. During 2023, the Company issued 12,055 original issue shares of common stock as a result of SARs exercises, 119,147 original issue shares of common stock for restricted stock units that vested and 278,687 original issue shares of common stock for performance shares that vested. Holders of stock-based compensation awards will often tender shares of common stock to the Company for payment of applicable withholding taxes. During 2023, 103,059 shares of common stock were tendered to the Company for such purposes. The Company considers all shares tendered as cancelled shares restored to the status of authorized but unissued shares, in accordance with New Jersey law. The Company also has a director stock program under which it issues shares of Company common stock to the non-employee directors of the Company who receive compensation under the Company’s 2009 Non-Employee Director Equity Compensation Plan, including the reinvestment of dividends for certain non-employee directors who elected to defer their shares pursuant to the dividend reinvestment feature of the Company's Deferred Compensation Plan for Directors and Officers (the "DCP"), as partial consideration for the directors’ services during the fiscal year. Under this program, the Company issued 31,715 original issue shares of common stock during 2023. In addition, the Company issued 2,796 original issue shares of common stock to officers of the Company who elected to defer their shares pursuant to the dividend reinvestment features of the Company's DCP during 2023. Stock Award Plans The Company has various stock award plans which provide or provided for the issuance of one or more of the following to key employees: SARs, incentive stock options, nonqualified stock options, restricted stock, restricted stock units, performance units or performance shares. Stock-based compensation expense for the years ended September 30, 2023, 2022 and 2021 was approximately $ 18.6 million, $ 17.6 million and $ 15.2 million, respectively. Stock-based compensation expense is included in operation and maintenance expense on the Consolidated Statements of Income. The total income tax benefit related to stock-based compensation expense during the years ended September 30, 2023, 2022 and 2021 was approximately $ 2.4 million, $ 2.5 million and $ 2.4 million, respectively. A portion of stock-based compensation expense is subject to capitalization under IRS uniform capitalization rules. Stock-based compensation of $ 0.1 million was capitalized under these rules during each of the years ended September 30, 2023, 2022 and 2021. The tax benefit related to stock-based compensation exercises and vestings was $ 1.2 million for the year ended September 30, 2023. Pursuant to registration statements for these plans, there were 1,510,900 shares available for future grant at September 30, 2023. These shares include shares available for future options, SARs, restricted stock and performance share grants. -94- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) SARs Transactions for 2023 involving SARs for all plans are summarized as follows: Number of Shares Subject To Option Weighted Average Exercise Price Aggregate Intrinsic Value (In thousands) Outstanding at September 30, 2022 72,008 $ 53.05 Granted in 2023 — $ — Exercised in 2023 ( 72,008 ) $ 53.05 Forfeited in 2023 — $ — Expired in 2023 — $ — Outstanding at September 30, 2023 — $ — $ — SARs exercisable at September 30, 2023 — $ — $ — The Company did no t grant any SARs during the years ended September 30, 2022 and 2021. The Company’s SARs included both performance-based and nonperformance-based SARs, but the performance conditions associated with the performance-based SARs at the time of grant were all subsequently met. The SARs are considered equity awards under the current authoritative guidance for stock-based compensation. The accounting for SARs is the same as the accounting for stock options. The total intrinsic value of SARs exercised during the years ended September 30, 2023 and 2022 totaled approximately $ 0.8 million and $ 2.0 million, respectively. During the year ended September 30, 2021, no SARs were exercised. There were no SARs that became fully vested during the years ended September 30, 2023, 2022 and 2021. The SARs that were outstanding at September 30, 2022 had been fully vested since fiscal 2017. Restricted Stock Units Transactions for 2023 involving nonperformance-based restricted stock units for all plans are summarized as follows: Number of Restricted Stock Units Weighted Average Fair Value per Award Outstanding at September 30, 2022 347,427 $ 44.58 Granted in 2023 133,173 $ 58.10 Vested in 2023 ( 119,147 ) $ 44.82 Forfeited in 2023 ( 19,267 ) $ 46.88 Outstanding at September 30, 2023 342,186 $ 49.63 The Company also granted 128,950 and 172,513 nonperformance-based restricted stock units during the years ended September 30, 2022 and 2021, respectively. The weighted average fair value of such nonperformance-based restricted stock units granted in 2022 and 2021 was $ 54.10 per share and $ 37.98 per share, respectively. As of September 30, 2023, unrecognized compensation expense related to nonperformance-based restricted stock units totaled approximately $ 7.5 million, which will be recognized over a weighted average period of 2.2 years. Vesting restrictions for the nonperformance-based restricted stock units outstanding at September 30, 2023 will lapse as follows: 2024 — 115,652 units; 2025 — 98,343 units; 2026 — 79,021 units; 2027 — 33,527 units; and 2028 — 15,643 units. -95- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) Performance Shares Transactions for 2023 involving performance shares for all plans are summarized as follows: Number of Performance Shares Weighted Average Fair Value per Award Outstanding at September 30, 2022 607,179 $ 48.60 Granted in 2023 202,259 $ 64.28 Vested in 2023 ( 278,687 ) $ 42.58 Forfeited in 2023 ( 22,805 ) $ 57.20 Change in Units Based on Performance Achieved 78,845 $ 40.69 Outstanding at September 30, 2023 586,791 $ 55.46 The Company also granted 195,397 and 309,470 performance shares during the years ended September 30, 2022 and 2021, respectively. The weighted average grant date fair value of such performance shares granted in 2022 and 2021 was $ 65.39 per share and $ 39.19 per share, respectively. As of September 30, 2023, unrecognized compensation expense related to performance shares totaled approximately $ 12.8 million, which will be recognized over a weighted average period of 1.7 years. Vesting restrictions for the outstanding performance shares at September 30, 2023 will lapse as follows: 2024 — 214,158 shares; 2025 — 179,320 shares; and 2026 — 193,313 shares. The performance shares granted during the years ended September 30, 2023, 2022 and 2021 include awards that must meet a performance goal related to either relative return on capital over a three-year performance cycle ("ROC performance shares"), methane intensity and greenhouse gas emissions reductions over a three-year performance cycle ("ESG performance shares") or relative shareholder return over a three-year performance cycle ("TSR performance shares"). The performance goal over the respective performance cycles for the ROC performance shares granted during 2023, 2022 and 2021 is the Company’s total return on capital relative to the total return on capital of other companies in a group selected by the Compensation Committee (“Report Group”). Total return on capital for a given company means the average of the Report Group companies’ returns on capital for each twelve-month period corresponding to each of the Company’s fiscal years during the performance cycle, based on data reported for the Report Group companies in the Bloomberg database. The number of these ROC performance shares that will vest and be paid will depend upon the Company’s performance relative to the Report Group and not upon the absolute level of return achieved by the Company. The fair value of the ROC performance shares is calculated by multiplying the expected number of shares that will be issued by the average market price of Company common stock on the date of grant reduced by the present value of forgone dividends over the vesting term of the award. The fair value is recorded as compensation expense over the vesting term of the award. The performance goal over the respective performance cycles for the ESG performance shares granted during 2023 and 2022 consists of two parts: reductions in the rates of intensity of methane emissions for each of the Company's operating segments, and reduction of the consolidated Company's total greenhouse gas emissions. The Company's Compensation Committee set specific target levels for methane intensity rates and total greenhouse gas emissions, and the performance goal is intended to incentivize and reward performance to the extent management achieves methane intensity and greenhouse gas reduction targets making progress towards the Company's 2030 goals. The number of these ESG performance shares that will vest and be paid out will depend upon the number of methane intensity segment targets achieved and whether the Company meets the total greenhouse gas emissions target. The fair value of these ESG performance shares is calculated by multiplying the expected number of shares that will be issued by the average market price of Company common stock on the date of grant reduced by the present value of forgone dividends over the vesting term of the award. -96- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) The fair value is recorded as compensation expense over the vesting term of the award. There were no ESG performance shares granted in 2021. The performance goal over the respective performance cycles for the TSR performance shares granted during 2023, 2022 and 2021 is the Company’s three-year total shareholder return relative to the three-year total shareholder return of the other companies in the Report Group. Three-year total shareholder return for a given company will be based on the data reported for that company (with the starting and ending stock prices over the performance cycle calculated as the average closing stock price for the prior calendar month and with dividends reinvested in that company’s securities at each ex-dividend date) in the Bloomberg database. The number of these TSR performance shares that will vest and be paid will depend upon the Company’s performance relative to the Report Group and not upon the absolute level of return achieved by the Company. The fair value price at the date of grant for the TSR performance shares is determined using a Monte Carlo simulation technique, which includes a reduction in value for the present value of forgone dividends over the vesting term of the award. This price is multiplied by the number of TSR performance shares awarded, the result of which is recorded as compensation expense over the vesting term of the award. In calculating the fair value of the award, the risk-free interest rate is based on the yield of a Treasury Note with a term commensurate with the remaining term of the TSR performance shares. The remaining term is based on the remainder of the performance cycle as of the date of grant. The expected volatility is based on historical daily stock price returns. For the TSR performance shares, it was assumed that there would be no forfeitures, based on the vesting term and the number of grantees. The following assumptions were used in estimating the fair value of the TSR performance shares at the date of grant: Year Ended September 30 2023 2022 2021 Risk-Free Interest Rate 4.03 % 0.85 % 0.19 % Remaining Term at Date of Grant (Years) 2.80 2.80 2.80 Expected Volatility 31.6 % 29.7 % 29.1 % Expected Dividend Yield (Quarterly) N/A N/A N/A Redeemable Preferred Stock As of September 30, 2023, there were 10,000,000 shares of $ 1 par value Preferred Stock authorized but unissued. Long-Term Debt The outstanding long-term debt is as follows: At September 30 2023 2022 (Thousands) Medium-Term Notes(1): 7.4 % due June 2025 $ 50,000 $ 99,000 Notes(1)(2)(3): 2.95 % to 5.50 % due July 2025 to March 2031 2,350,000 2,550,000 Total Long-Term Debt 2,400,000 2,649,000 Less Unamortized Discount and Debt Issuance Costs 15,515 16,591 Less Current Portion(4) — 549,000 $ 2,384,485 $ 2,083,409 (1) The Medium-Term Notes and Notes are unsecured. -97- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) (2) The holders of these notes may require the Company to repurchase their notes at a price equal to 101 % of the principal amount in the event of both a change in control and a ratings downgrade to a rating below investment grade. (3) The interest rate payable on $ 300.0 million of 4.75 % notes, $ 300.0 million of 3.95 % notes, $ 500.0 million of 2.95 % notes and $ 300.0 million of 5.50 % notes will be subject to adjustment from time to time, with a maximum of 2.00 %, if certain change of control events involving a material subsidiary result in a downgrade of the credit rating assigned to the notes to below investment grade (or if the credit rating assigned to the notes is subsequently upgraded). The interest rate payable on $ 500.0 million of 5.50 % notes will be subject to adjustment from time to time, with a maximum adjustment of 2.00 %, such that the coupon will not exceed 7.50 %, if there is a downgrade of the credit rating assigned to the notes to a rating below investment grade. A downgrade with a resulting increase to the coupon does not preclude the coupon from returning to its original rate if the Company's credit rating is subsequently upgraded. (4) None of the Company's long-term debt as of September 30, 2023 had a maturity date within the following twelve-month period. Current Portion of Long-Term Debt at September 30, 2022 consisted of $ 500.0 million of 3.75 % notes and $ 49.0 million of 7.395 % notes. The Company redeemed $ 150.0 million of the 3.75 % notes on November 25, 2022 using a portion of the proceeds from short-term borrowings, as discussed below. In March 2023, the Company redeemed the remaining $ 350.0 million of the 3.75 % notes as well as the $ 49.0 million of 7.395 % notes . On May 18, 2023, the Company issued $ 300.0 million of 5.50 % notes due October 1, 2026. After deducting underwriting discounts, commissions and other debt issuance costs, the net proceeds to the Company amounted to $ 297.3 million. The proceeds of this debt issuance were used for general corporate purposes, including to repay all indebtedness under the $ 250.0 million unsecured committed delayed draw term loan under the 364-Day Credit Agreement, discussed below. On February 24, 2021, the Company issued $ 500.0 million of 2.95 % notes due March 1, 2031. After deducting underwriting discounts, commissions and other debt issuance costs, the net proceeds to the Company amounted to $ 495.3 million. The proceeds of this debt issuance were used for general corporate purposes, including the redemption of $ 500.0 million of 4.90 % notes on March 11, 2021 that were scheduled to mature in December 2021. The Company redeemed those notes for $ 515.7 million, plus accrued interest. The early redemption premium of $ 15.7 million was recorded to Interest Expense on Long-Term Debt on the Consolidated Income Statement during the quarter ended March 31, 2021. As of September 30, 2023, the aggregate principal amounts of long-term debt maturing during the next five years and thereafter are as follows: zero in 2024, $ 500.0 million in 2025, $ 500.0 million in 2026, $ 600.0 million in 2027, $ 300.0 million in 2028, and $ 500.0 million thereafter. Short-Term Borrowings The Company historically has obtained short-term funds either through bank loans or the issuance of commercial paper. On February 28, 2022, the Company entered into a Credit Agreement (as amended from time to time, the "Credit Agreement") with a syndicate of twelve banks. The Credit Agreement replaced the previous Fourth Amended and Restated Credit Agreement and a previous 364-Day Credit Agreement. The Credit Agreement provides a $ 1.0 billion unsecured committed revolving credit facility with a maturity date of February 26, 2027. On June 30, 2022, the Company entered into a 364-Day Credit Agreement with a syndicate of five banks, all of which are also lenders under the Credit Agreement. The 364-Day Credit Agreement provided an additional $ 250.0 million unsecured committed delayed draw term loan credit facility with a maturity date of June 29, 2023. The Company elected to draw $ 250.0 million under the facility on October 27, 2022. The Company used the proceeds for general corporate purposes, which included using $ 150.0 million for the -98- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) November 25, 2022 redemption of a portion of the Company's outstanding long-term debt with a maturity date of March 1, 2023. All indebtedness under the 364-Day Credit Agreement was repaid on May 18, 2023. The Company also has uncommitted lines of credit with financial institutions for general corporate purposes. Borrowings under these uncommitted lines of credit would be made at competitive market rates. The uncommitted credit lines are revocable at the option of the financial institution and are reviewed on an annual basis. The Company anticipates that its uncommitted lines of credit generally will be renewed or substantially replaced by similar lines. Other financial institutions may also provide the Company with uncommitted or discretionary lines of credit in the future. The total amount available to be issued under the Company’s commercial paper program is $ 500.0 million. The commercial paper program is backed by the Credit Agreement. At September 30, 2023, the Company had outstanding commercial paper of $ 287.5 million with a weighted average interest rate on the commercial paper of 6.13 %. The Company did not have any outstanding short-term notes payable to banks at September 30, 2023. At September 30, 2022, the Company had outstanding short-term notes payable to banks of $ 60.0 million, all of which was issued under the Credit Agreement, with an interest rate of 4.02 %. The Company did not have any outstanding commercial paper at September 30, 2022. Debt Restrictions The Credit Agreement provides that the Company's debt to capitalization ratio will not exceed 0.65 at the last day of any fiscal quarter. For purposes of calculating the debt to capitalization ratio, the Company's total capitalization will be increased by adding back 50 % of the aggregate after-tax amount of non-cash charges directly arising from any ceiling test impairment occurring on or after July 1, 2018, not to exceed $ 400 million. Since July 1, 2018, the Company recorded non-cash, after-tax ceiling test impairments totaling $ 381.4 million. As a result, at September 30, 2023, $ 190.7 million was added back to the Company's total capitalization for purposes of the calculation under the Credit Agreement. On May 3, 2022, the Company entered into Amendment No. 1 to the Credit Agreement with the same twelve banks under the initial Credit Agreement. The amendment further modified the definition of consolidated capitalization, for purposes of calculating the debt to capitalization ratio under the Credit Agreement, to exclude, beginning with the quarter ended June 30, 2022, all unrealized gains or losses on commodity-related derivative financial instruments and up to $ 10 million in unrealized gains or losses on other derivative financial instruments included in Accumulated Other Comprehensive Income (Loss) within Total Comprehensive Shareholders' Equity on the Company's consolidated balance sheet. Under the Credit Agreement, such unrealized losses will not negatively affect the calculation of the debt to capitalization ratio, and such unrealized gains will not positively affect the calculation. At September 30, 2023, the Company’s debt to capitalization ratio, as calculated under the Credit Agreement was 0.46 . The constraints specified in the Credit Agreement would have permitted an additional $ 3.17 billion in short-term and/or long-term debt to be outstanding at September 30, 2023 before the Company’s debt to capitalization ratio exceeded 0.65 . A downgrade in the Company’s credit ratings could increase borrowing costs, negatively impact the availability of capital from banks, commercial paper purchasers and other sources, and require the Company's subsidiaries to post letters of credit, cash or other assets as collateral with certain counterparties. If the Company is not able to maintain investment grade credit ratings, it may not be able to access commercial paper markets. However, the Company expects that it could borrow under its credit facilities or rely upon other liquidity sources. The Credit Agreement contains a cross-default provision whereby the failure by the Company or its significant subsidiaries to make payments under other borrowing arrangements, or the occurrence of certain events affecting those other borrowing arrangements, could trigger an obligation to repay any amounts outstanding under the Credit Agreement. In particular, a repayment obligation could be triggered if (i) the Company or any of its significant subsidiaries fails to make a payment when due of any principal or interest on -99- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) any other indebtedness aggregating $ 40.0 million or more or (ii) an event occurs that causes, or would permit the holders of any other indebtedness aggregating $ 40.0 million or more to cause, such indebtedness to become due prior to its stated maturity. In order to issue incremental long-term debt, the Company must meet an interest coverage test under its existing indenture covenants. In general, the Company’s operating income, subject to certain adjustments, over a consecutive 12-month period within the 15 months preceding the debt issuance, must be not less than two times the total annual interest charges on the Company’s long-term debt, taking into account the incremental issuance. In addition, taking into account the incremental issuance, and using a pro forma balance sheet as of the last day of the 12-month period used in the interest coverage test, the Company must maintain a ratio of long-term debt to consolidated assets (as defined under the indenture) of not more than 60 %. Under the Company's existing indenture covenants at September 30, 2023, the Company would have been permitted to issue up to a maximum of approximately $ 3.43 billion in additional unsubordinated long-term indebtedness at then current market interest rates, in addition to being able to issue new indebtedness to replace existing debt (further limited by the debt to capitalization ratio constraint under the Company's Credit Agreement, as discussed above). The Company's present liquidity position is believed to be adequate to satisfy known demands. It is possible, depending on amounts reported in various income statement and balance sheet line items, that the indenture covenants could, for a period of time, prevent the Company from issuing incremental unsubordinated long-term debt, or significantly limit the amount of such debt that could be issued. Losses incurred as a result of significant impairments of oil and gas properties have in the past resulted in such temporary restrictions. The indenture covenants would not preclude the Company from issuing new long-term debt to replace existing long-term debt, or from issuing additional short-term debt. Please refer to Part II, Item 7, Critical Accounting Estimates section above for a sensitivity analysis concerning commodity price changes and their impact on the ceiling test. The Company’s 1974 indenture pursuant to which $ 50.0 million (or 2.1 %) of the Company’s long-term debt (as of September 30, 2023) was issued, contains a cross-default provision whereby the failure by the Company to perform certain obligations under other borrowing arrangements could trigger an obligation to repay the debt outstanding under the indenture. In particular, a repayment obligation could be triggered if the Company fails (i) to pay any scheduled principal or interest on any debt under any other indenture or agreement, or (ii) to perform any other term in any other such indenture or agreement, and the effect of the failure causes, or would permit the holders of the debt to cause, the debt under such indenture or agreement to become due prior to its stated maturity, unless cured or waived. Note I — Fair Value Measurements The FASB authoritative guidance regarding fair value measurements establishes a fair-value hierarchy and prioritizes the inputs used in valuation techniques that measure fair value. Those inputs are prioritized into three levels. Level 1 inputs are unadjusted quoted prices in active markets for assets or liabilities that the Company can access at the measurement date. Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly at the measurement date. Level 3 inputs are unobservable inputs for the asset or liability at the measurement date. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy levels. The following table sets forth, by level within the fair value hierarchy, the Company’s financial assets and liabilities (as applicable) that were accounted for at fair value on a recurring basis as of September 30, 2023 and 2022. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. -100- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) At Fair Value as of September 30, 2023 Recurring Fair Value Measures Level 1 Level 2 Level 3 Netting Adjustments(1) Total(1) (Dollars in thousands) Assets: Cash Equivalents — Money Market Mutual Funds $ 39,332 $ — $ — $ — $ 39,332 Derivative Financial Instruments: Over the Counter Swaps — Gas — 65,800 — ( 37,508 ) 28,292 Over the Counter No Cost Collars — Gas — 30,966 — ( 14,745 ) 16,221 Contingent Consideration for Asset Sale — 7,277 — — 7,277 Foreign Currency Contracts — 150 — ( 1,453 ) ( 1,303 ) Other Investments: Balanced Equity Mutual Fund 15,837 — — — 15,837 Fixed Income Mutual Fund 15,897 — — — 15,897 Total $ 71,066 $ 104,193 $ — $ ( 53,706 ) $ 121,553 Liabilities: Derivative Financial Instruments: Over the Counter Swaps — Gas $ — $ 68,311 $ — $ ( 37,508 ) $ 30,803 Over the Counter No Cost Collars — Gas — 14,950 — ( 14,745 ) 205 Foreign Currency Contracts — 1,454 — ( 1,453 ) 1 Total $ — $ 84,715 $ — $ ( 53,706 ) $ 31,009 Total Net Assets/(Liabilities) $ 71,066 $ 19,478 $ — $ — $ 90,544 At Fair Value as of September 30, 2022 Recurring Fair Value Measures Level 1 Level 2 Level 3 Netting Adjustments(1) Total(1) (Dollars in thousands) Assets: Cash Equivalents — Money Market Mutual Funds $ 35,015 $ — $ — $ — $ 35,015 Hedging Collateral Deposits 91,670 — — — 91,670 Derivative Financial Instruments: Over the Counter Swaps — Gas — 5,177 — ( 4,178 ) 999 Contingent Consideration for Asset Sale — 8,176 — — 8,176 Foreign Currency Contracts — 128 — ( 128 ) — Other Investments: Balanced Equity Mutual Fund 19,506 — — — 19,506 Fixed Income Mutual Fund 33,348 — — — 33,348 Total $ 179,539 $ 13,481 $ — $ ( 4,306 ) $ 188,714 Liabilities: Derivative Financial Instruments: Over the Counter Swaps — Gas $ — $ 517,464 $ — $ ( 4,178 ) $ 513,286 Over the Counter No Cost Collars — Gas — 270,453 — — 270,453 Foreign Currency Contracts — 2,048 — ( 128 ) 1,920 Total $ — $ 789,965 $ — $ ( 4,306 ) $ 785,659 Total Net Assets/(Liabilities) $ 179,539 $ ( 776,484 ) $ — $ — $ ( 596,945 ) (1) Netting Adjustments represent the impact of legally-enforceable master netting arrangements that allow the Company to net gain and loss positions held with the same counterparties. The net asset or net liability for each counterparty is recorded as an asset or liability on the Company’s balance sheet. -101- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) Derivative Financial Instruments At September 30, 2023, the derivative financial instruments reported in Level 2 consist of natural gas price swap agreements, natural gas no cost collars, and foreign currency contracts, all of which are used in the Company's Exploration and Production segment. Hedging collateral deposits of $ 91.7 million at September 30, 2022, which were associated with the price swap agreements, no cost collars and foreign currency contracts, have been reported in Level 1. The fair value of the Level 2 price swap agreements and no cost collars is based on an internal cash flow model that uses observable inputs (i.e. SOFR based discount rates for the price swap agreements and basis differential information, if applicable, at active natural gas and crude oil trading markets). The fair value of the Level 2 foreign currency contracts is determined using the market approach based on observable market transactions of forward Canadian currency rates. The authoritative guidance for fair value measurements and disclosures require consideration of the impact of nonperformance risk (including credit risk) from a market participant perspective in the measurement of the fair value of assets and liabilities. At September 30, 2023, the Company determined that nonperformance risk associated with the price swap agreements, no cost collars and foreign currency contracts would have no material impact on its financial position or results of operation. To assess nonperformance risk, the Company considered information such as any applicable collateral posted, master netting arrangements, and applied a market-based method by using the counterparty's (assuming the derivative is in a gain position) or the Company’s (assuming the derivative is in a loss position) credit default swaps rates. Derivative financial instruments reported in Level 2 at September 30, 2023 and September 30, 2022 also includes the contingent consideration associated with the sale of the Exploration and Production segment's California assets on June 30, 2022, which is discussed at Note B — Asset Acquisitions and Divestitures and at Note J — Financial Instruments. The fair value of the contingent consideration was calculated using a Monte Carlo simulation model that uses observable inputs, including the ICE Brent closing price as of the valuation date, initial and max trigger price, volatility, risk free rate, time of maturity and counterparty risk. For the years ended September 30, 2023 and 2022, there were no assets or liabilities measured at fair value and classified as Level 3. Note J — Financial Instruments Long-Term Debt The fair market value of the Company’s debt, as presented in the table below, was determined using a discounted cash flow model, which incorporates the Company’s credit ratings and current market conditions in determining the yield, and subsequently, the fair market value of the debt. Based on these criteria, the fair market value of long-term debt, including current portion, was as follows: At September 30 2023 Carrying Amount 2023 Fair Value 2022 Carrying Amount 2022 Fair Value (Thousands) Long-Term Debt $ 2,384,485 $ 2,210,478 $ 2,632,409 $ 2,453,209 The fair value amounts are not intended to reflect principal amounts that the Company will ultimately be required to pay. Carrying amounts for other financial instruments recorded on the Company’s Consolidated Balance Sheets approximate fair value. The fair value of long-term debt was calculated using observable inputs (U.S. Treasuries for the risk-free component and company specific credit spread information — generally obtained from recent trade activity in the debt). As such, the Company considers the debt to be Level 2. Any temporary cash investments, notes payable to banks and commercial paper are stated at cost. Temporary cash investments are considered Level 1, while notes payable to banks and commercial paper are -102- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) considered to be Level 2. Given the short-term nature of the notes payable to banks and commercial paper, the Company believes cost is a reasonable approximation of fair value. Other Investments The components of the Company's Other Investments are as follows (in thousands): At September 30 2023 2022 (Thousands) Life Insurance Contracts $ 42,242 $ 42,171 Equity Mutual Fund 15,837 19,506 Fixed Income Mutual Fund 15,897 33,348 $ 73,976 $ 95,025 Investments in life insurance contracts are stated at their cash surrender values or net present value. Investments in an equity mutual fund and a fixed income mutual fund are stated at fair value based on quoted market prices with changes in fair value recognized in net income. The insurance contracts and equity mutual fund are primarily informal funding mechanisms for various benefit obligations the Company has to certain employees. The fixed income mutual fund is primarily an informal funding mechanism for certain regulatory obligations that the Company has to Utility segment customers in its Pennsylvania jurisdiction, as discussed in Note F — Regulatory Matters, and for various benefit obligations the Company has to certain employees. Derivative Financial Instruments The Company uses derivative financial instruments to manage commodity price risk in the Exploration and Production segment. The Company enters into over-the-counter no cost collar and swap agreements for natural gas to manage the price risk associated with forecasted sales of natural gas. In addition, the Company also enters into foreign exchange forward contracts to manage the risk of currency fluctuations associated with transportation costs denominated in Canadian currency in the Exploration and Production segment. These instruments are accounted for as cash flow hedges. The duration of the Company’s cash flow hedges does not typically exceed 5 years while the foreign currency forward contracts do not exceed 7 years. On June 30, 2022, the Company completed the sale of Seneca’s California assets. Under the terms of the purchase and sale agreement, the Company can receive up to three annual contingent payments between calendar year 2023 and calendar year 2025, not to exceed $ 10 million per year, with the amount of each annual payment calculated as $ 1.0 million for each $ 1 per barrel that the ICE Brent Average for each calendar year exceeds $ 95 per barrel up to $ 105 per barrel. The Company has determined that this contingent consideration meets the definition of a derivative under the authoritative accounting guidance. Changes in the fair value of this contingent consideration are marked-to-market each reporting period, with changes in fair value recognized in Other Income (Deductions) on the Consolidated Statement of Income. The fair value of this contingent consideration was estimated to be $ 7.3 million and $ 8.2 million at September 30, 2023 and September 30, 2022, respectively. A $ 0.9 million mark-to-market adjustment was recorded during the year ended September 30, 2023. The Company has presented its net derivative assets and liabilities as “Fair Value of Derivative Financial Instruments” on its Consolidated Balance Sheets at September 30, 2023 and September 30, 2022. Cash Flow Hedges For derivative financial instruments that are designated and qualify as a cash flow hedge, the gain or loss on the derivative is reported as a component of other comprehensive income (loss) and reclassified into earnings in the period or periods during which the hedged transaction affects earnings. -103- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) As of September 30, 2023, the Company had 411.3 Bcf of natural gas commodity derivative contracts (swaps and no cost collars) outstanding. As of September 30, 2023, the Company was hedging a total of $ 56.9 million of forecasted transportation costs denominated in Canadian dollars with foreign currency forward contracts. As of September 30, 2023, the Company had $ 4.6 million of net hedging gains after taxes included in the accumulated other comprehensive income (loss) balance. Of this amount, it is expected that $ 11.5 million of unrealized gains after taxes will be reclassified into the Consolidated Statement of Income within the next 12 months as the underlying hedged transactions are recorded in earnings. The remaining unrealized losses will be being reclassified into the Consolidated Statement of Income in subsequent periods.

Because of this sale, the Company terminated its remaining crude oil derivative contracts and discontinued hedge accounting for such contracts. A loss of $ 44.6 million was reclassified from Accumulated Other Comprehensive Income (Loss) on the Consolidated Balance Sheet to Operating Revenues on the Consolidated Statement of Income for the year ended September 30, 2022. This loss is included in the reported reclassification amounts. Credit Risk The Company may be exposed to credit risk on any of the derivative financial instruments that are in a gain position. Credit risk relates to the risk of loss that the Company would incur as a result of nonperformance by counterparties pursuant to the terms of their contractual obligations. To mitigate such credit risk, management performs a credit check, and then on a quarterly basis monitors counterparty credit exposure. The majority of the Company’s counterparties are financial institutions and energy traders. The Company has over the-counter swap positions, no cost collars and applicable foreign currency forward contracts with nineteen counterparties of which eleven are in a net gain position. On average, the Company had $ 3.9 million of credit exposure per counterparty in a gain position at September 30, 2023. The maximum credit exposure per counterparty in a gain position at September 30, 2023 was $ 16.1 million. As of September 30, 2023, no collateral was received from the counterparties by the Company. The Company's gain position on such derivative financial instruments had not exceeded the established thresholds at which the counterparties would be required to post collateral, nor had the counterparties' credit ratings declined to levels at which the counterparties were required to post collateral. As of September 30, 2023, sixteen of the nineteen counterparties to the Company’s outstanding derivative financial contracts (specifically the over-the-counter swaps, over-the-counter no cost collars and applicable -104- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) foreign currency forward contracts) had a common credit-risk related contingency feature. In the event the Company’s credit rating increases or falls below a certain threshold (applicable debt ratings), the available credit extended to the Company would either increase or decrease. A decline in the Company’s credit rating, in and of itself, would not cause the Company to be required to post or increase the level of its hedging collateral deposits (in the form of cash deposits, letters of credit or treasury debt instruments). If the Company’s outstanding derivative financial instrument contracts with a credit-risk contingency feature were in a liability position (or if the liability were larger) and/or the Company’s credit rating declined, then hedging collateral deposits or an increase to such deposits could be required. At September 30, 2023, the fair market value of the derivative financial instrument liabilities with a credit-risk related contingency feature was $ 7.7 million according to the Company's internal model (discussed in Note I — Fair Value Measurements) and no hedging collateral deposits were required to be posted by the Company at September 30, 2023. Depending on the movement of commodity prices in the future, it is possible that these liability positions could swing into asset positions, at which point the Company would be exposed to credit risk on its derivative financial instruments. In that case, the Company's counterparties could be required to post hedging collateral deposits. The Company’s requirement to post hedging collateral deposits and the Company's right to receive hedging collateral deposits is based on the fair value determined by the Company’s counterparties, which may differ from the Company’s assessment of fair value. Note K — Retirement Plan and Other Post-Retirement Benefits The Company has a tax-qualified, noncontributory, defined-benefit retirement plan (Retirement Plan). The Retirement Plan covers certain non-collectively bargained employees hired before July 1, 2003 and certain collectively bargained employees hired before November 1, 2003. Certain non-collectively bargained employees hired after June 30, 2003 and certain collectively bargained employees hired after October 31, 2003 are eligible for a Retirement Savings Account benefit provided under the Company’s defined contribution Tax-Deferred Savings Plans. Costs associated with the Retirement Savings Account were $ 5.7 million, $ 5.3 million and $ 4.8 million for the years ended September 30, 2023, 2022 and 2021, respectively. Costs associated with the Company’s contributions to the Tax-Deferred Savings Plans, exclusive of the costs associated with the Retirement Savings Account, were $ 8.2 million, $ 7.8 million and $ 7.2 million for the years ended September 30, 2023, 2022 and 2021, respectively. The Company provides health care and life insurance benefits (other post-retirement benefits) for a majority of its retired employees. The other post-retirement benefits cover certain non-collectively bargained employees hired before January 1, 2003 and certain collectively bargained employees hired before October 31, 2003. The Company’s policy is to fund the Retirement Plan with at least an amount necessary to satisfy the minimum funding requirements of applicable laws and regulations and not more than the maximum amount deductible for federal income tax purposes. The Company has established VEBA trusts for its other post-retirement benefits. Contributions to the VEBA trusts are tax deductible, subject to limitations contained in the Internal Revenue Code and regulations and are made to fund employees’ other post-retirement benefits, as well as benefits as they are paid to current retirees. In addition, the Company has established 401(h) accounts for its other post-retirement benefits. They are separate accounts within the Retirement Plan trust used to pay retiree medical benefits for the associated participants in the Retirement Plan. Although these accounts are in the Retirement Plan trust, for funding status purposes as shown below, the 401(h) accounts are included in Fair Value of Assets under Other Post-Retirement Benefits. Contributions are tax-deductible when made, subject to limitations contained in the Internal Revenue Code and regulations. The expected return on Retirement Plan assets, a component of net periodic benefit cost shown in the tables below, is applied to the market-related value of plan assets. The market-related value of plan assets is the market value as of the measurement date adjusted for variances between actual returns and expected returns -105- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) (from previous years) that have not been reflected in net periodic benefit costs. The expected return on other post-retirement benefit assets (i.e. the VEBA trusts and 401(h) accounts), which is a component of net periodic benefit cost shown in the tables below, is applied to the fair value of assets as of the measurement date. Reconciliations of the Benefit Obligations, Plan Assets and Funded Status, as well as the components of Net Periodic Benefit Cost and the Weighted Average Assumptions of the Retirement Plan and other post-retirement benefits are shown in the tables below. The components of net periodic benefit cost other than service cost are presented in Other Income (Deductions) on the Consolidated Statements of Income. The date used to measure the Benefit Obligations, Plan Assets and Funded Status is September 30 for fiscal years 2023, 2022 and 2021.

All the other subsidiaries of the Company utilize the corridor approach. The Net Periodic Benefit Cost (Income) in the table above includes the effects of regulation. The Company recovers pension and other post-retirement benefit costs in its Utility and Pipeline and Storage segments in accordance with the applicable regulatory commission authorizations. Certain of those commission authorizations established tracking mechanisms which allow the Company to record the difference between the amount of pension and other post-retirement benefit costs recoverable in rates and the amounts of such costs as determined under the existing authoritative guidance as either a regulatory asset or liability, as appropriate. Any activity under the tracking mechanisms (including the amortization of pension and other post-retirement regulatory assets and liabilities) is reflected in the Net Amortization and Deferral for Regulatory Purposes line item above. In addition to the Retirement Plan discussed above, the Company also has Non-Qualified benefit plans that cover a group of management employees whose income level has exceeded certain IRS thresholds or who have been designated as participants by the Chief Executive Officer of the Company. These plans provide for defined benefit payments upon retirement of the management employee, or to the spouse upon death of the management employee. The net periodic benefit costs associated with these plans were $ 8.3 million, $ 8.9 -107- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) million and $ 8.3 million in 2023, 2022 and 2021, respectively. The components of net periodic benefit cost other than service costs associated with these plans are presented in Other Income (Deductions) on the Consolidated Statements of Income. The accumulated benefit obligations for the plans were $ 58.5 million, $ 64.9 million and $ 76.9 million at September 30, 2023, 2022 and 2021, respectively. The projected benefit obligations for the plans were $ 69.5 million, $ 77.2 million and $ 95.8 million at September 30, 2023, 2022 and 2021, respectively. At September 30, 2023, $ 13.1 million of the projected benefit obligation is recorded in Other Accruals and Current Liabilities and the remaining $ 56.4 million is recorded in Other Liabilities on the Consolidated Balance Sheets. At September 30, 2022, $ 17.5 million of the projected benefit obligation was recorded in Other Accruals and Current Liabilities and the remaining $ 59.7 million was recorded in Other Liabilities on the Consolidated Balance Sheets. At September 30, 2021, $ 15.4 million of the projected benefit obligation was recorded in Other Accruals and Current Liabilities and the remaining $ 80.4 million was recorded in Other Liabilities on the Consolidated Balance Sheets. The weighted average discount rates for these plans were 5.91 %, 5.49 % and 2.15 % as of September 30, 2023, 2022 and 2021, respectively and the weighted average rate of compensation increase for these plans was 8.00 % as of September 30, 2023, 2022 and 2021.

The effect of the discount rate change for the Retirement Plan in 2021 was to decrease the projected benefit obligation of the Retirement Plan by $ 11.2 million. The Company did not make any cash contributions to the Retirement Plan during the year ended September 30, 2023. The Company expects that the annual contribution to the Retirement Plan in 2024 will be in the range of zero to $ 5.0 million. The following Retirement Plan benefit payments, which reflect expected future service, are expected to be paid by the Retirement Plan during the next five years and the five years thereafter: $ 67.9 million in 2024; $ 67.4 million in 2025; $ 66.9 million in 2026; $ 66.2 million in 2027; $ 65.5 million in 2028; and $ 310.4 million in the five years thereafter. The effect of the discount rate change in 2023 was to decrease the other post-retirement benefit obligation by $ 10.7 million. The mortality improvement projection scale was updated, which decreased the other post-retirement benefit obligation in 2023 by $ 0.4 million. The health care cost trend rates were updated, which increased the other post-retirement benefit obligation in 2023 by $ 3.2 million. Other actuarial experience decreased the other post-retirement benefit obligation in 2023 by $ 12.9 million, the majority of which was attributable to a revision in assumed per-capita claims cost, premiums, retiree contributions and retiree drug subsidy assumptions based on actual experience. The effect of the discount rate change in 2022 was to decrease the other post-retirement benefit obligation by $ 98.9 million. The mortality improvement projection scale was updated, which increased the other post-retirement benefit obligation in 2022 by $ 1.1 million. Other actuarial experience decreased the other post-retirement benefit obligation in 2022 by $ 22.5 million, the majority of which was attributable to a revision in assumed per-capita claims cost, premiums, retiree contributions and retiree drug subsidy assumptions based on actual experience. The effect of the discount rate change in 2021 was to decrease the other post-retirement benefit obligation by $ 2.5 million. The mortality improvement projection scale was updated, which decreased the other post-retirement benefit obligation in 2021 by $ 2.0 million. The health care cost trend rates were updated, which decreased the other post-retirement benefit obligation in 2021 by $ 3.7 million. Other actuarial experience decreased the other post-retirement benefit obligation in 2021 by $ 26.6 million, the majority of which was attributable to a revision in assumed per-capita claims cost, premiums, retiree contributions and retiree drug subsidy assumptions based on actual experience. The Medicare Prescription Drug, Improvement, and Modernization Act of 2003 provides for a prescription drug benefit under Medicare (Medicare Part D), as well as a federal subsidy to sponsors of retiree health care benefit plans that provide a benefit that is at least actuarially equivalent to Medicare Part D.

The fair values disclosed in the above tables may not be indicative of net realizable value or reflective of future fair values. Furthermore, although the Company believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date. The following tables provide a reconciliation of the beginning and ending balances of the Retirement Plan and other post-retirement benefit assets measured at fair value on a recurring basis where the determination of fair value includes significant unobservable inputs (Level 3). For the years ended September 30, 2023 and September 30, 2022, there were no transfers from Level 1 to Level 2. In addition, as shown in the following tables, there were no transfers in or out of Level 3.

The return assumption reflects the anticipated long-term rate of return on the plan’s current and future assets. The Company utilizes projected capital market conditions and the plan’s target asset class and investment manager allocations to set the assumption regarding the expected return on plan assets. The long-term investment objective of the Retirement Plan trust, the VEBA trusts and the 401(h) accounts is to achieve the target total return in accordance with the Company’s risk tolerance. Assets are diversified utilizing a mix of equities, fixed income and other securities (including real estate). Risk tolerance is established through consideration of plan liabilities, plan funded status and corporate financial condition. The assets of the Retirement Plan trust, VEBA trusts and the 401(h) accounts have no significant concentrations of risk in any one country (other than the United States), industry or entity. In fiscal 2021 and fiscal 2022, capital market conditions led to significant improvements in the funded status of the Retirement Plan. As a result, the Company reduced the return seeking portion of its assets during both years, particularly equity securities and return seeking fixed income securities, held in the Retirement Plan, and increased its allocation to hedging fixed income securities in conjunction with the Company’s liability driven investment strategy. The actual asset allocations as of September 30, 2023 are noted in the table above, and such allocations are subject to change, but the majority of the assets will remain hedging fixed income assets. Given the level of the VEBA trust and 401(h) assets in relation to the Other Post-Retirement Benefits, the majority of those assets are and will remain in fixed income securities. Investment managers are retained to manage separate pools of assets. Comparative market and peer group performance of individual managers and the total fund are monitored on a regular basis, and reviewed by the Company’s Retirement Committee on at least a quarterly basis. The Company determines the service and interest cost components of net periodic benefit cost using the spot rate approach, which uses individual spot rates along the yield curve that correspond to the timing of each benefit payment in order to determine the discount rate. The individual spot rates along the yield curve are determined by an above mean methodology in that the coupon interest rates that are in the lower 50th percentile are excluded based on the assumption that the Company would not utilize more expensive (i.e. lower yield) instruments to settle its liabilities. -113- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) Note L — Commitments and Contingencies Environmental Matters The Company is subject to various federal, state and local laws and regulations relating to the protection of the environment. The Company has established procedures for the ongoing evaluation of its operations to identify potential environmental exposures and to comply with regulatory requirements. It is the Company’s policy to accrue estimated environmental clean-up costs (investigation and remediation) when such amounts can reasonably be estimated and it is probable that the Company will be required to incur such costs. At September 30, 2023, the Company has estimated its remaining clean-up costs related to former manufactured gas plant sites will be approximately $ 3.7 million. The Company's liability for such clean-up costs has been recorded in Other Liabilities on the Consolidated Balance Sheet at September 30, 2023. The Company has recovered its environmental clean-up costs through rate recovery and is currently not aware of any material additional exposure to environmental liabilities. However, changes in environmental laws and regulations, new information or other factors could have an adverse financial impact on the Company. Northern Access Project On February 3, 2017, Supply Corporation and Empire received FERC approval of the Northern Access project described herein. Shortly thereafter, the NYDEC issued a Notice of Denial of the federal Clean Water Act Section 401 Water Quality Certification and other state stream and wetland permits for the New York portion of the project (the Water Quality Certification for the Pennsylvania portion of the project was received in January of 2017). Subsequently, FERC issued an Order finding that the NYDEC exceeded the statutory time frame to take action under the Clean Water Act and, therefore, waived its opportunity to approve or deny the Water Quality Certification. FERC denied rehearing requests associated with its Order and FERC's decisions were appealed. The Second Circuit Court of Appeals issued an order upholding the FERC waiver orders. In addition, in the Company's state court litigation challenging the NYDEC's actions with regard to various state permits, the New York State Supreme Court issued a decision finding these permits to be preempted. The Company remains committed to the project and, on June 29, 2022, received an extension of time from FERC, until December 31, 2024, to construct the project, which is the subject of an ongoing appeal at the U.S. Court of Appeals for the D.C. Circuit. As of September 30, 2023, the Company has spent approximately $ 55.9 million on the project, all of which is recorded on the balance sheet. Other The Company, in its Utility segment and Exploration and Production segment, has entered into contractual commitments in the ordinary course of business, including commitments to purchase gas, transportation, and storage service to meet customer gas supply needs. The future gas purchase, transportation and storage contract commitments during the next five years and thereafter are as follows: $ 201.7 million in 2024, $ 91.1 million in 2025, $ 113.8 million in 2026, $ 118.3 million in 2027, $ 121.7 million in 2028 and $ 768.9 million thereafter. Gas prices within the gas purchase contracts are variable based on NYMEX prices adjusted for basis. In the Utility segment, these costs are subject to state commission review, and are being recovered in customer rates. Management believes that, to the extent any stranded pipeline costs are generated by the unbundling of services in the Utility segment’s service territory, such costs will be recoverable from customers. The Company, in its Pipeline and Storage segment, Gathering segment and Utility segment, has entered into several contractual commitments associated with various pipeline, compressor and gathering system modernization and expansion projects. As of September 30, 2023, the future contractual commitments related to the system modernization and expansion projects are $ 74.9 million in 2024, $ 8.4 million in 2025, $ 7.2 million in 2026, $ 5.9 million in 2027, $ 3.3 million in 2028 and $ 4.7 million thereafter. The Company, in its Exploration and Production segment, has entered into contractual obligations to support its development activities and operations in Pennsylvania, including hydraulic fracturing and other well -114- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) completion services, well tending services, well workover activities, tubing and casing purchases, production equipment purchases, water hauling services and contracts for drilling rig services. The future contractual commitments are $ 279.5 million in 2024, $ 185.1 million in 2025, and $ 47.3 million in 2026. There are no contractual commitments extending beyond 2026. In addition to the regulatory matters discussed in Note F — Regulatory Matters, the Company is involved in other regulatory and litigation matters arising in the normal course of business. These other regulatory and litigation matters may include, for example, tax, regulatory or other governmental audits, inspections, investigations, negligence claims and other proceedings. These matters may involve state and federal taxes, safety, compliance with regulations, rate base, cost of service and purchased gas cost issues, among other things. While these other matters arising in the normal course of business could have a material effect on earnings and cash flows in the period in which they are resolved, an estimate of the possible loss or range of loss, if any, cannot be made at this time. Note M — Business Segment Information The Company reports financial results for four segments: Exploration and Production, Pipeline and Storage, Gathering, and Utility. The division of the Company’s operations into reportable segments is based upon a combination of factors including differences in products and services, regulatory environment and geographic factors. The Exploration and Production segment, through Seneca, is engaged in exploration for and development of natural gas reserves in the Appalachian region of the United States. The Pipeline and Storage segment operations are regulated by the FERC for both Supply Corporation and Empire. Supply Corporation transports and stores natural gas for utilities (including Distribution Corporation), natural gas marketers, exploration and production companies (including Seneca) and pipeline companies in the northeastern United States markets. Empire transports and stores natural gas for major industrial companies, utilities (including Distribution Corporation) and power producers in New York State. Empire also transports natural gas for natural gas marketers and exploration and production companies (including Seneca) from natural gas producing areas in Pennsylvania to markets in New York and to interstate pipeline delivery points with access to additional markets in the northeastern United States and Canada. The Gathering segment is comprised of Midstream Company’s operations. Midstream Company builds, owns and operates natural gas processing and pipeline gathering facilities in the Appalachian region and currently provides gathering services primarily to Seneca. The Utility segment operations are regulated by the NYPSC and the PaPUC and are carried out by Distribution Corporation. Distribution Corporation sells natural gas to retail customers and provides natural gas transportation services in western New York and northwestern Pennsylvania. The data presented in the tables below reflects financial information for the segments and reconciliations to consolidated amounts. The accounting policies of the segments are the same as those described in Note A — Summary of Significant Accounting Policies. Sales of products or services between segments are billed at regulated rates or at market rates, as applicable. The Company evaluates segment performance based on income before discontinued operations (when applicable). When this is not applicable, the Company evaluates performance based on net income. -115- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) Year Ended September 30, 2023 Exploration and Production Pipeline and Storage Gathering Utility Total Reportable Segments All Other Corporate and Intersegment Eliminations Total Consolidated (Thousands) Revenue from External Customers(1)(2) $ 958,455 $ 259,646 $ 13,891 $ 941,779 $ 2,173,771 $ — $ — $ 2,173,771 Intersegment Revenues $ — $ 119,545 $ 216,426 $ 581 $ 336,552 $ — $ ( 336,552 ) $ — Interest Income $ 3,259 $ 7,052 $ 534 $ 6,296 $ 17,141 $ — $ ( 5,662 ) $ 11,479 Interest Expense $ 54,317 $ 43,499 $ 14,989 $ 34,233 $ 147,038 $ 157 $ ( 15,309 ) $ 131,886 Depreciation, Depletion and Amortization $ 241,142 $ 70,827 $ 35,725 $ 61,450 $ 409,144 $ — $ 429 $ 409,573 Income Tax Expense (Benefit) $ 87,796 $ 34,489 $ 36,128 $ 7,267 $ 165,680 $ ( 164 ) $ ( 983 ) $ 164,533 Segment Profit: Net Income (Loss) $ 232,275 $ 100,501 $ 99,724 $ 48,395 $ 480,895 $ ( 531 ) $ ( 3,498 ) $ 476,866 Expenditures for Additions to Long-Lived Assets $ 737,725 $ 141,877 $ 103,295 $ 139,922 $ 1,122,819 $ — $ 754 $ 1,123,573 At September 30, 2023 (Thousands) Segment Assets $ 2,814,218 $ 2,427,214 $ 912,923 $ 2,247,743 $ 8,402,098 $ 4,795 $ ( 126,633 ) $ 8,280,260 Year Ended September 30, 2022 Exploration and Production Pipeline and Storage Gathering Utility Total Reportable Segments All Other Corporate and Intersegment Elimination Total Consolidated (Thousands) Revenue from External Customers(1)(3) $ 1,010,464 $ 265,415 $ 12,086 $ 897,916 $ 2,185,881 $ — $ 165 $ 2,186,046 Intersegment Revenues $ — $ 111,629 $ 202,757 $ 305 $ 314,691 $ 6 $ ( 314,697 ) $ — Interest Income $ 1,929 $ 2,275 $ 198 $ 2,730 $ 7,132 $ 3 $ ( 1,024 ) $ 6,111 Interest Expense $ 53,401 $ 42,492 $ 16,488 $ 24,115 $ 136,496 $ 4 $ ( 6,143 ) $ 130,357 Depreciation, Depletion and Amortization $ 208,148 $ 67,701 $ 33,998 $ 59,760 $ 369,607 $ — $ 183 $ 369,790 Income Tax Expense (Benefit) $ 43,898 $ 35,043 $ 24,949 $ 17,165 $ 121,055 $ 3 $ ( 4,429 ) $ 116,629 Significant Item: Gain on Sale of Assets $ 12,736 $ — $ — $ — $ 12,736 $ — $ — $ 12,736 Segment Profit: Net Income (Loss) $ 306,064 $ 102,557 $ 101,111 $ 68,948 $ 578,680 $ ( 9 ) $ ( 12,650 ) $ 566,021 Expenditures for Additions to Long-Lived Assets $ 565,791 $ 95,806 $ 55,546 $ 111,033 $ 828,176 $ — $ 1,212 $ 829,388 At September 30, 2022 (Thousands) Segment Assets $ 2,507,541 $ 2,394,697 $ 878,796 $ 2,299,473 $ 8,080,507 $ 2,036 $ ( 186,281 ) $ 7,896,262 -116- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) Year Ended September 30, 2021 Exploration and Production Pipeline and Storage Gathering Utility Total Reportable Segments All Other Corporate and Intersegment Eliminations Total Consolidated (Thousands) Revenue from External Customers(1) $ 836,697 $ 234,397 $ 3,116 $ 666,920 $ 1,741,130 $ 1,173 $ 356 $ 1,742,659 Intersegment Revenues $ — $ 109,160 $ 190,148 $ 331 $ 299,639 $ 49 $ ( 299,688 ) $ — Interest Income $ 211 $ 1,085 $ 259 $ 2,117 $ 3,672 $ 230 $ 486 $ 4,388 Interest Expense $ 69,662 $ 40,976 $ 17,493 $ 21,795 $ 149,926 $ — $ ( 3,569 ) $ 146,357 Depreciation, Depletion and Amortization $ 182,492 $ 62,431 $ 32,350 $ 57,457 $ 334,730 $ 394 $ 179 $ 335,303 Income Tax Expense (Benefit) $ 33,370 $ 28,812 $ 28,876 $ 14,007 $ 105,065 $ 11,438 $ ( 1,821 ) $ 114,682 Significant Non-Cash Item: Impairment of Oil and Gas Producing Properties $ 76,152 $ — $ — $ — $ 76,152 $ — $ — $ 76,152 Significant Item: Gain on Sale of Assets $ — $ — $ — $ — $ — $ 51,066 $ — $ 51,066 Segment Profit: Net Income (Loss) $ 101,916 $ 92,542 $ 80,274 $ 54,335 $ 329,067 $ 37,645 $ ( 3,065 ) $ 363,647 Expenditures for Additions to Long-Lived Assets $ 381,408 $ 252,316 $ 34,669 $ 100,845 $ 769,238 $ — $ 673 $ 769,911 At September 30, 2021 (Thousands) Segment Assets $ 2,286,058 $ 2,296,030 $ 837,729 $ 2,148,267 $ 7,568,084 $ 4,146 $ ( 107,405 ) $ 7,464,825 (1) All Revenue from External Customers originated in the United States.

See further discussion in Note J — Financial Instruments. -119- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) Reserve Quantity Information The Company's proved oil and gas reserve estimates are prepared by the Company's petroleum engineers who meet the qualifications of Reserve Estimator per the "Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserve Information" promulgated by the Society of Petroleum Engineers as of June 25, 2019. The Company maintains comprehensive internal reserve guidelines and a continuing education program designed to keep its staff up to date with current SEC regulations and guidance. The Company's Vice President of Reservoir Engineering is the primary technical person responsible for overseeing the Company's reserve estimation process and engaging and overseeing the third party reserve audit. His qualifications include a Bachelor of Science Degree in Petroleum Engineering and over 14 years of Petroleum Engineering experience with independent oil and gas companies, licensure as a Professional Engineer and is a member of the Society of Petroleum Engineers. The Company maintains a system of internal controls over the reserve estimation process. Management reviews the price, heat content, lease operating cost and future investment assumptions used in the economic model to determine the reserves. The Vice President of Reservoir Engineering reviews and approves all new reserve assignments and significant reserve revisions. Access to the reserve database is restricted. Significant changes to the reserve report are reviewed by senior management on a quarterly basis. Periodically, the Company's internal audit department assesses the design of these controls and performs testing to determine the effectiveness of such controls. All of the Company's reserve estimates are audited annually by Netherland, Sewell & Associates, Inc. (NSAI). Since 1961, NSAI has evaluated gas and oil properties and independently certified petroleum reserve quantities in the United States and internationally under the Texas Board of Professional Engineers Registration No. F-002699. The primary technical persons (employed by NSAI) that are responsible for leading the audit include a professional engineer registered with the State of Texas (consulting at NSAI since 2019 and with over 6 years of prior industry experience in petroleum engineering) and a professional geoscientist registered in the State of Texas (consulting at NSAI since 2008 and with over 11 years of prior industry experience in petroleum geosciences). NSAI was satisfied with the methods and procedures used by the Company to prepare its reserve estimates at September 30, 2023 and did not identify any problems which would cause it to take exception to those estimates. The reliable technologies that were utilized in estimating the reserves include wire line open-hole log data, performance data, log cross sections, core data, 2D and 3D seismic data and statistical analysis. The statistical method utilized production performance from both the Company's and competitors’ wells. Geophysical data includes data from the Company's wells, third-party wells, published documents and state data-sites, and 2D and 3D seismic data. These were used to confirm continuity of the formation. -120- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) Gas MMcf U.S. Appalachian Region West Coast Region Total Company Proved Developed and Undeveloped Reserves: September 30, 2020 3,296,113 28,972 3,325,085 Extensions and Discoveries 689,395 (1) — 689,395 Revisions of Previous Estimates 19,940 3,033 22,973 Production ( 312,300 ) (2) ( 1,720 ) ( 314,020 ) September 30, 2021 3,693,148 30,285 3,723,433 Extensions and Discoveries 837,510 (1) — 837,510 Revisions of Previous Estimates 2,882 71 2,953 Production ( 341,700 ) (2) ( 1,211 ) ( 342,911 ) Sale of Minerals in Place ( 21,178 ) ( 29,145 ) ( 50,323 ) September 30, 2022 4,170,662 — 4,170,662 Extensions and Discoveries 670,438 (1) — 670,438 Revisions of Previous Estimates 32,379 — 32,379 Production ( 372,271 ) (2) — ( 372,271 ) Purchases of Minerals in Place 33,876 — 33,876 September 30, 2023 4,535,084 — 4,535,084 Proved Developed Reserves: September 30, 2020 2,744,851 28,972 2,773,823 September 30, 2021 3,061,178 30,285 3,091,463 September 30, 2022 3,312,568 — 3,312,568 September 30, 2023 3,550,034 — 3,550,034 Proved Undeveloped Reserves: September 30, 2020 551,262 — 551,262 September 30, 2021 631,970 — 631,970 September 30, 2022 858,094 — 858,094 September 30, 2023 985,050 — 985,050 (1) Extensions and discoveries include 180 Bcf (during 2021), 301 Bcf (during 2022) and 163 Bcf (during 2023), of Marcellus Shale gas (which exceed 15 % of total reserves) in the Appalachian region.

PUD reserves in the Utica Shale increased from 503 Bcfe at September 30, 2022 to 873 Bcfe at September 30, 2023. PUD reserves in the Marcellus Shale decreased from 355 Bcfe at September 30, 2022 to 112 Bcfe at September 30, 2023. The Company’s total PUD reserves were 21.7 % of total proved reserves at September 30, 2023, up from 20.6 % of total proved reserves at September 30, 2022. The Company’s PUD reserves increased from 636 Bcfe at September 30, 2021 to 858 Bcfe at September 30, 2022. PUD reserves in the Utica Shale increased from 411 Bcfe at September 30, 2021 to 503 Bcfe at September 30, 2022. PUD reserves in the Marcellus Shale increased from 220 Bcfe at September 30, 2021 to 355 Bcfe at September 30, 2022. PUD reserves in the West Coast region decreased from 5 Bcfe at September 30, 2021 to zero at September 30, 2022. The Company’s total PUD reserves were 20.6 % of total proved reserves at September 30, 2022, up from 16.5 % of total proved reserves at September 30, 2021. The increase in PUD reserves in 2023 of 127 Bcfe is a result of 554 Bcfe in new PUD reserve additions, 14 Bcfe for one PUD well added back into the schedule and 23 Bcfe in upward revisions to remaining PUD reserves. These upward revisions were partially offset by 402 Bcfe in PUD conversions to developed reserves ( 275 Bcfe from the Marcellus Shale and 127 Bcfe from the Utica Shale), and 62 Bcfe in PUD reserves removed for seven PUD locations due to schedule and pad layout changes. -122- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) The increase in PUD reserves in 2022 of 222 Bcfe is a result of 502 Bcfe in new PUD reserve additions and 23 Bcfe in upward revisions to remaining PUD reserves, partially offset by 287 Bcfe in PUD conversions to developed reserves ( 55 Bcfe from the Marcellus Shale, 231 Bcfe from the Utica Shale and 1 Bcfe from the West Coast region), and 13 Bcfe in PUD reserves removed for one Utica PUD location due to pad layout changes. The remaining change of 3 Bcf was due to removing West Coast region PUDs included in the beginning of year balances through development and divesture of Seneca's California assets. The Company invested $ 342 million during the year ended September 30, 2023 to convert 402 Bcfe ( 440 Bcfe after revisions) of predominantly Marcellus and Utica Shale PUD reserves to developed reserves. This represents 47 % of the net PUD reserves recorded at September 30, 2022. The Company developed 39 of 77 PUD locations in 2023. PUD expenditures in 2023 were higher than the 2022 estimate due to schedule changes and changes in service costs. The Company invested $ 154 million during the year ended September 30, 2022 to convert 287 Bcfe ( 333 Bcfe after revisions) of predominantly Marcellus and Utica Shale PUD reserves to developed reserves. This represents 45 % of the net PUD reserves recorded at September 30, 2021. In the Appalachian region, 31 of 65 PUD locations were developed while the West Coast region developed 6 of 17 PUD locations prior to the divesture. PUD expenditures in 2022 were lower than the 2021 estimate primarily due to changes in the development schedule. In 2024, the Company estimates that it will invest approximately $ 315 million to develop its PUD reserves. The Company is committed to developing its PUD reserves within five years as required by the SEC’s final rule on Modernization of Oil and Gas Reporting. Since that rule was adopted, and over the last five years, the Company developed 39 % of its beginning year PUD reserves in fiscal 2019, 36 % of its beginning year PUD reserves in fiscal 2020, 34 % of its beginning year PUD reserves in fiscal 2021, 45 % of its beginning year PUD reserves in fiscal 2022 and 47 % of its beginning year PUD reserves in fiscal 2023. At September 30, 2023, the Company does not have any proved undeveloped reserves that have been on the books for more than five years at the corporate level, country level or field level. All of the Company’s proved reserves are in the United States. Standardized Measure of Discounted Future Net Cash Flows Relating to Proved Oil and Gas Reserves The Company cautions that the following presentation of the standardized measure of discounted future net cash flows is intended to be neither a measure of the fair market value of the Company’s oil and gas properties, nor an estimate of the present value of actual future cash flows to be obtained as a result of their development and production. It is based upon subjective estimates of proved reserves only and attributes no value to categories of reserves other than proved reserves, such as probable or possible reserves, or to unproved acreage. Furthermore, in accordance with the SEC’s final rule on Modernization of Oil and Gas Reporting, it is based on the unweighted arithmetic average of the first day of the month oil and gas prices for each month within the twelve-month period prior to the end of the reporting period and costs adjusted only for existing contractual changes. It assumes an arbitrary discount rate of 10 %. Thus, it gives no effect to future price and cost changes certain to occur under widely fluctuating political and economic conditions. The standardized measure is intended instead to provide a means for comparing the value of the Company’s proved reserves at a given time with those of other oil- and gas-producing companies than is provided by a simple comparison of raw proved reserve quantities. -123- NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) Year Ended September 30 2023 2022 2021 (Thousands) United States Future Cash Inflows $ 11,947,345 $ 19,209,099 $ 10,175,182 Less: Future Production Costs 3,538,389 3,138,226 3,423,629 Future Development Costs 1,095,096 781,847 597,662 Future Income Tax Expense at Applicable Statutory Rate 1,867,457 3,876,272 1,397,175 Future Net Cash Flows 5,446,403 11,412,754 4,756,716 Less: 10% Annual Discount for Estimated Timing of Cash Flows 2,874,295 5,964,424 2,403,144 Standardized Measure of Discounted Future Net Cash Flows $ 2,572,108 $ 5,448,330 $ 2,353,572 The principal sources of change in the standardized measure of discounted future net cash flows were as follows: Year Ended September 30 2023 2022 2021 (Thousands) United States Standardized Measure of Discounted Future Net Cash Flows at Beginning of Year $ 5,448,330 $ 2,353,572 $ 1,222,470 Sales, Net of Production Costs ( 767,487 ) ( 1,572,402 ) ( 626,132 ) Net Changes in Prices, Net of Production Costs ( 3,918,392 ) 4,132,889 1,478,995 Extensions and Discoveries 237,057 1,355,257 462,040 Changes in Estimated Future Development Costs ( 222,233 ) ( 32,160 ) 48,247 Purchases of Minerals in Place 34,346 — — Sales of Minerals in Place — ( 311,308 ) — Previously Estimated Development Costs Incurred 342,024 154,253 81,239 Net Change in Income Taxes at Applicable Statutory Rate 959,728 ( 1,180,349 ) ( 415,993 ) Revisions of Previous Quantity Estimates 33,192 3,316 ( 52,383 ) Accretion of Discount and Other 425,543 545,262 155,089 Standardized Measure of Discounted Future Net Cash Flows at End of Year $ 2,572,108 $ 5,448,330 $ 2,353,572 -124- Item 9 Changes in and Disagreements with Accountants on Accounting and Financial Disclosure None.
