MANAGEMENT COMMENTS

David P. Bauer, President and Chief Executive Officer of National Fuel Gas Company, stated: “National Fuel closed out an exceptional fiscal 2025 with a strong fourth quarter. Driven by great execution across our businesses, adjusted earnings per share increased by 58% compared to the prior year.

“In our Integrated Upstream and Gathering segment, results for the quarter highlight the unique combination of continued operational excellence, along with the best-in-class nature of our assets in the EDA. Our talented team continues to find ways to improve and expand upon our already deep inventory of highly economic drilling locations in this area, where we added 220 new Upper Utica locations this quarter, extending our peer-leading EDA inventory life to more than 15 years. Complementing this inventory expansion, our team recently executed a precedent agreement for new firm transportation capacity from Tioga County to premium markets with an expected in-service date of late 2028, further supporting our long-term growth plans

“The outlook for our regulated businesses is equally promising. In addition to our long-standing modernization program, which we expect will continue to drive rate base growth, we see new capacity additions enhancing our growth outlook. The Tioga Pathway and Shippingport Lateral expansion projects continue to progress as planned, and we are seeing increasing interest in further capacity additions across our FERC-regulated pipeline system. Additionally, our recently announced strategic acquisition of CenterPoint Energy’s Ohio natural gas utility business will significantly grow the Company’s regulated asset base, adding high-quality operations in a neighboring, cold weather state, with a constructive political and regulatory backdrop.

“With our investment grade balance sheet, strong growth outlook, and increasing scale, the Company is well positioned to deliver meaningful value to shareholders in the years to come.”

FISCAL 2026 GUIDANCE UPDATE

National Fuel is providing its formal guidance for adjusted earnings per share for fiscal 2026 with a range of $7.60 to $8.10.

The Company is assuming an average NYMEX natural gas price of $3.75 per MMBtu in fiscal 2026, which approximates the current NYMEX forward curve at this time. Given the continued volatility in NYMEX natural gas prices, the Company is providing the following sensitivities to its adjusted earnings per share guidance range:

NYMEX Assumption
($/MMBtu)Fiscal 2026
Adjusted Earnings
Per Share Sensitivities$3.00$6.55 - $7.05$4.00$8.00 - $8.50

All of the other major assumptions incorporated into this updated guidance range are consistent with the Company’s preliminary guidance disclosed last quarter.

The acquisition of CenterPoint Energy's Ohio natural gas utility business is expected to close in the fourth quarter of calendar 2026 and, therefore, is not expected to impact fiscal 2026 guidance. Fiscal 2026 guidance also excludes expected financing and acquisition related costs.

Additional details on the Company’s updated forecast assumptions and business segment guidance for fiscal 2026 are outlined in the table on page 7.

DISCUSSION OF FOURTH QUARTER RESULTS BY SEGMENT

The following earnings discussion of each operating segment for the quarter ended September 30, 2025 is summarized in a tabular form on pages 8 and 9 of this report (earnings drivers for the fiscal year ended September 30, 2025 are summarized on pages 10 and 11). It may be helpful to refer to those tables while reviewing this discussion.

During the quarter ended September 30, 2025, the Company determined that it was appropriate to consolidate its Exploration and Production and Gathering segments into a single financial reporting segment, which will be presented moving forward as National Fuel’s Integrated Upstream and Gathering segment. This updated presentation is intended to provide additional clarity as to the interdependence of the Company’s exploration and production and gathering businesses in bringing Appalachian natural gas to market. Prior year segment information shown below has been restated to reflect this change in presentation. A more detailed description of the Company's business segments will be provided in the Company's Form 10-K for fiscal 2025.

Note that management defines adjusted earnings as reported GAAP earnings adjusted for items impacting comparability, and adjusted EBITDA as reported GAAP earnings before the following items: interest expense, income taxes, depreciation, depletion and amortization, other income and deductions, impairments, and other items reflected in operating income that impact comparability.

Integrated Upstream and Gathering Segment

The Integrated Upstream and Gathering segment's exploration and production operations are carried out by Seneca Resources Company, LLC (“Seneca”) and the segment's gathering operations are carried out by National Fuel Gas Midstream Company, LLC’s ("Gathering"). Seneca explores for, develops, and produces primarily natural gas reserves in Pennsylvania. Gathering constructs, owns and operates natural gas gathering pipelines and compression facilities in the Appalachian region, which primarily delivers Seneca's production and, to a lesser extent, third party Appalachian production to the interstate pipeline system.

Three Months Ended September 30,(in thousands) 2025 2024 VarianceGAAP Earnings$103,493 $(142,072) $245,565 Impairment of assets — 272,358 (272,358)Tax impact of impairment of assets — (68,269) 68,269 Unrealized (gain) loss on derivative asset (2022 CA asset sale) — 1,700 (1,700)Tax impact of unrealized (gain) loss on derivative asset 3,402 (461) 3,863 Adjusted Earnings$106,895 $63,256 $43,639 Adjusted EBITDA$241,093 $173,246 $67,847

The Integrated Upstream and Gathering segment's fourth quarter GAAP earnings increased $245.6 million versus the prior year. This positive benefit was primarily driven by non-cash impairment charges that did not occur in the current period relative to fiscal 2024, where $272.4 million ($204.1 million after-tax) was recorded, the vast majority of which was related to a pre-tax ceiling test impairment to write-down the carrying value of Seneca’s reserves under the full cost method of accounting. GAAP earnings also included a one-time impact related to the income taxes in connection with a contingent consideration tied to the June 2022 divestiture of Seneca’s California assets.

Excluding items impacting comparability, Seneca and Gathering's adjusted earnings in the fourth quarter increased $43.6 million primarily due to higher production and realized natural gas prices, as well as lower per unit operating expenses.

During the fourth quarter, Seneca produced 112 Bcf of natural gas, an increase of 20 Bcf, or 21%, from the prior year. Two highly prolific Utica pads turned in line this year in Tioga County were the main drivers behind this increase in production.

Seneca’s weighted average realized natural gas price, after the impact of hedging and transportation costs, was $2.61 per Mcf, an increase of $0.21 per Mcf from the prior year. This increase was primarily due to higher NYMEX prices and higher spot prices at local sales points in Pennsylvania.

Three Months Ended September 30,(Cost per Mcf) 2025 2024 VarianceUpstream General and Administrative Expense (“G&A”)$0.17 $0.20 $(0.03)Lease Operating Expense (“LOE”)$0.13 $0.18 $(0.05)Gathering O&M Expense$0.13 $0.11 $0.02 Taxes and Other$0.10 $0.08 $0.02 Total Cash Operating Costs$0.53 $0.57 $(0.04)Depreciation, Depletion and Amortization Expense (“DD&A”)$0.74 $0.80 $(0.06)Total Operating Costs$1.27 $1.37 $(0.10)

On a per unit basis, fourth quarter total cash operating costs were $0.04 lower compared to the prior year, primarily due to higher production, as well as lower LOE, specifically lower repairs and maintenance costs. DD&A for the quarter was $0.74 per Mcf, a decrease of $0.06 per Mcf from the prior year, largely due to ceiling test impairments recorded in prior quarters that lowered Seneca’s full cost pool depletable base.

Proved Reserves Year-End Update

Seneca’s total proved reserves at September 30, 2025 were 4,981 Bcfe, an increase of 229 Bcfe, or 5%, from September 30, 2024. This increase was a result of Seneca replacing 154% of its fiscal 2025 production. Proved developed reserves at the end of fiscal 2025 were 3,665 Bcfe, representing 74% of total proved reserves. In fiscal 2025, Seneca added 633 Bcfe of proved reserve extensions and discoveries and 23 Bcfe of net positive revisions due to improvements in well performance and price revisions, partially offset by changes in development plans.

Pipeline and Storage Segment

The Pipeline and Storage segment’s operations are carried out by National Fuel Gas Supply Corporation (“Supply Corporation”) and Empire Pipeline, Inc. (“Empire”). The Pipeline and Storage segment provides natural gas transportation and storage services to affiliated and non-affiliated companies through an integrated system of pipelines and underground natural gas storage fields in western New York and Pennsylvania.

Three Months Ended September 30,(in thousands) 2025 2024 VarianceGAAP Earnings$27,938 $(5,812) $33,750 Impairment of assets — 46,075 (46,075)Tax impact of impairment of assets — (12,316) 12,316 Adjusted Earnings$27,938 $27,947 $(9) Adjusted EBITDA$62,639 $62,527 $112

The Pipeline and Storage segment’s fourth quarter GAAP earnings increased $33.8 million versus the prior year primarily due to an impairment charge of $46.1 million ($33.8 million after-tax) to write down the carrying value of certain assets associated with Supply Corporation and Empire's Northern Access project, as the Company determined it was unlikely to pursue construction of the project.

Excluding items impacting comparability, fourth quarter adjusted earnings were relatively flat compared to the prior year.

Utility Segment

The Utility segment operations are carried out by National Fuel Gas Distribution Corporation (“Distribution Corporation”), which sells or transports natural gas to customers located in western New York and northwestern Pennsylvania.

Three Months Ended September 30,(in thousands) 2025 2024 VarianceGAAP Earnings$(17,790) $(16,759) $(1,031) Adjusted EBITDA$2,036 $(228) $2,264

The Utility segment’s fourth quarter GAAP earnings decreased $1.0 million, or 6%, primarily as a result of increased operation and maintenance ("O&M") expense and income tax expense which more than offset an increase in customer margin.

For the fourth quarter, customer margin (operating revenue less purchased gas sold) increased $5.3 million, largely due to an increase in rates as part of the Utility's New York rate case settlement, which became effective October 1, 2024.

O&M expense increased $3.8 million primarily driven by higher personnel costs, partially offset by a reduction in uncollectible expenses as a result of a tracker implemented as part of the New York rate case settlement. Further, the increase in the Utility segment's income tax expense (or lower income tax benefit) was driven by a higher effective tax rate.

Corporate and All Other

The Company’s operations that are included in Corporate and All Other generated a combined net loss of $6.3 million, an increase of $3.3 million from the prior year net loss, in part due to higher operating expenses which are largely attributable to professional fees related to the previously announced Ohio utility acquisition.

AND SUBSIDIARIES

GUIDANCE SUMMARY

As discussed on page 2, the Company is revising its adjusted earnings per share guidance for fiscal 2026. Additional details on the Company's forecast assumptions and business segment guidance are outlined in the table below. As a reminder, the acquisition of CenterPoint Energy's Ohio natural gas utility business is expected to close in the fourth quarter of calendar 2026, and therefore, is not expected to impact fiscal 2026 guidance. Fiscal 2026 guidance also excludes expected financing and acquisition related costs.

While the Company expects to record certain adjustments to unrealized gain or loss on investments during the fiscal year ending September 30, 2026, the amounts of these and other potential adjustments are not reasonably determinable at this time. As such, the Company is unable to provide earnings guidance other than on a non-GAAP basis.

NON-GAAP FINANCIAL MEASURES

In addition to financial measures calculated in accordance with generally accepted accounting principles (GAAP), this press release contains information regarding adjusted earnings, adjusted EBITDA and free cash flow, which are non-GAAP financial measures. The Company believes that these non-GAAP financial measures are useful to investors because they provide an alternative method for assessing the Company's ongoing operating results or liquidity and for comparing the Company’s financial performance to other companies. The Company's management uses these non-GAAP financial measures for the same purpose, and for planning and forecasting purposes. The presentation of non-GAAP financial measures is not meant to be a substitute for financial measures in accordance with GAAP.

Management defines adjusted earnings as reported GAAP earnings before items impacting comparability. The following table reconciles National Fuel's reported GAAP earnings to adjusted earnings for the three and twelve months ended September 30, 2025 and 2024:

Management defines free cash flow as net cash provided by operating activities, less net cash used in investing activities, adjusted for acquisitions and divestitures. The Company is unable to provide a reconciliation of any projected free cash flow measure to its comparable GAAP financial measure without unreasonable efforts. This is due to an inability to calculate the comparable GAAP projected metrics, including operating income and total production costs, given the unknown effect, timing, and potential significance of certain income statement items.
