NATIONAL FUEL REPORTS SECOND QUARTER EARNINGS

WILLIAMSVILLE, N.Y.: National Fuel Gas Company (“National Fuel” or the “Company”) (NYSE:NFG) today announced consolidated results for the second quarter of its 2024 fiscal year and for the six months ended March 31, 2024.

FISCAL 2024 SECOND QUARTER SUMMARY

•GAAP net income of $166.3 million, or $1.80 per share, compared to GAAP net income of $140.9 million, or $1.53 per share, in the prior year, an increase of 18% per share.

•Adjusted operating results of $165.3 million, or $1.79 per share, compared to $141.8 million, or $1.54 per share, in the prior year, an increase of 16% per share (see non-GAAP reconciliation on page 2).

•Pipeline and Storage segment revenue was up $12.9 million, or 14%, from the prior year, primarily due to the resolution of the National Fuel Gas Supply Corporation (“Supply Corporation”) rate proceeding, which is expected to increase annual revenues by $56 million.

•Exploration and Production segment produced 103 Bcf of natural gas, an increase of 10% from the prior year, driven by strong operational execution, particularly in the highly productive Eastern Development Area (“EDA”).

•Gathering segment revenue increased $7.0 million, or 12%, from the prior year, primarily as a result of a 15% increase in throughput, driven by both Seneca Resources and third-party producers.

•Utility segment earnings increased by $13.0 million, or 41%, from the prior year largely due to an increase in base rate delivery revenues from our 2023 Pennsylvania jurisdiction rate case settlement.

•Company is revising its fiscal 2024 earnings guidance to a range of $4.75 to $5.05 per share, excluding items impacting comparability, while lowering capital expenditure guidance to a range of $885 to $980 million.

MANAGEMENT COMMENTS

David P. Bauer, President and Chief Executive Officer of National Fuel Gas Company, stated: “National Fuel had an excellent second quarter with adjusted operating results increasing 16% compared to the prior year. Leading the way was strong performance from our regulated businesses, which collectively delivered earnings growth of 36%, primarily driven by the completion of rate proceedings in our FERC-regulated Supply Corporation and the Pennsylvania jurisdiction of our Utility business.

“Operationally, we continue to execute on strategic objectives across our asset base. Of note, the ongoing transition to the EDA is exceeding expectations and was the main driver behind the double-digit growth in Seneca’s production and Gathering business throughput. While lower natural gas prices were a headwind compared to last year’s second quarter, our disciplined hedging program mitigated a majority of the commodity price impacts.

“Looking ahead, the underlying strength of each of our businesses, and our commitment to hedging through the cycles, provide confidence in our long-term outlook for the Company. This outlook supports our long-standing commitment to shareholder returns, which was further enhanced in the second quarter with the commencement of a new $200 million share buyback program. Together, our outlook for growth and commitment to returning capital to shareholders position the Company to create value in the coming years.”

FISCAL 2024 GUIDANCE UPDATE

National Fuel is revising its fiscal 2024 earnings guidance to reflect the results of the second quarter along with updated forecast assumptions and projections. The Company is now projecting that earnings, excluding anticipated non-cash ceiling test impairment charges and other items impacting comparability, will be within the range of $4.75 to $5.05 per share, a decrease of $0.15 per share from the midpoint of the Company’s prior guidance range. The decrease from the Company’s prior earnings guidance primarily reflects the full year impact of lower natural gas prices and price-related production curtailments at Seneca during the second quarter, partially offset by an increase in revenue in the Pipeline and Storage segment.

The Company is now assuming that NYMEX natural gas prices will average $2.00 per MMBtu for the remainder of fiscal 2024, a decrease of $0.40 per MMBtu. For guidance purposes, the Company’s updated natural gas price projections approximate the current NYMEX forward curve and consider the impact of local sales point differentials and new physical firm sales, transportation, and financial hedge contracts. Given the Company's price projections, we expect to experience a ceiling test impairment in each of the two remaining quarters of fiscal 2024.

The Exploration and Production segment’s fiscal 2024 net production is now expected to be in the range of 390 to 405 Bcf, which reflects the impacts of approximately 5 Bcf of price-related curtailments due to low in-basin pricing during the second quarter. This guidance range does not incorporate any additional price-related curtailments over the remainder of the fiscal year. Seneca currently has firm sales contracts in place for approximately 95% of its projected remaining fiscal 2024 natural gas production, significantly limiting its exposure to in-basin markets. Approximately 74% of expected remaining production is either matched by a financial hedge or was entered into at a fixed price.

The Pipeline and Storage segment’s revenues are now expected to be in the range of $400 to $420 million, a $10 million increase at the midpoint. The increase is attributable to several factors, including the settlement of the Supply Corporation rate case.

The Company’s consolidated capital expenditures are now expected to be in the range of $885 to $980 million, a $10 million decrease at the midpoint. During the first half of the fiscal year, the Company operated a two-rig program with a dedicated completion crew, while also periodically utilizing a top-hole rig. As previously planned, the Company dropped a rig at the end of the second quarter and expects to maintain a reduced activity level for the balance of the fiscal year.

The Company’s other guidance assumptions are outlined in the table on page 7.

DISCUSSION OF SECOND QUARTER RESULTS BY SEGMENT

The following earnings discussion of each operating segment for the quarter ended March 31, 2024 is summarized in a tabular form on pages 8 and 9 of this report (earnings drivers for the six months ended March 31, 2024 are summarized on pages 10 and 11). It may be helpful to refer to those tables while reviewing this discussion.

Note that management defines Adjusted Operating Results 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.

Upstream Business

Exploration and Production Segment

The Exploration and Production segment operations are carried out by Seneca Resources Company, LLC (“Seneca”). Seneca explores for, develops and produces primarily natural gas reserves in Pennsylvania.

	Three Months Ended
	March 31,
(in thousands)	2024		2023		Variance
GAAP Earnings	$	62,065	$	60,982	$	1,083
Unrealized (gain) loss on derivative asset, net of tax	(389)		1,794		(2,183)
Adjusted Operating Results	$	61,676	$	62,776	$	(1,100)
Adjusted EBITDA	$	172,068	$	154,574	$	17,494

Seneca’s second quarter GAAP earnings increased $1.1 million versus the prior year. Higher natural gas production, lower per unit lease operating and transportation expense (“LOE”), and lower other taxes were partially offset by lower realized natural gas prices, and increases in per unit depreciation, depletion and amortization (“DD&A”) and interest expenses.

The GAAP earnings increase also includes an unrealized gain of $0.5 million ($0.4 million after-tax) recognized during the current-year second quarter related to an increase in the fair value of contingent consideration Seneca received in connection with the June 2022 divestiture of its California assets. In the prior year's second quarter, Seneca recorded an unrealized loss of $2.5 million ($1.8 million after-tax) on that contingent consideration. Excluding these unrealized gains and losses, Seneca's adjusted operating results decreased $1.1 million.

During the second quarter, Seneca produced 102.9 Bcf of natural gas, an increase of 9.6 Bcf, or 10%, from the prior year, despite the impact of approximately 5 Bcf of price-related curtailments due to low in-basin pricing. The increase in production was largely due to production from new Marcellus and Utica wells in Seneca's EDA.

Seneca’s average realized natural gas price, after the impact of hedging and transportation costs, was $2.56 per Mcf, a decrease of $0.02 per Mcf from the prior year. Pre-hedging realized natural gas prices decreased 29% from the prior year; however, Seneca’s hedging portfolio, which experienced a gain of $0.58 per Mcf during the quarter, mitigated a significant portion of this impact.

On a per unit basis, LOE was $0.68 per Mcf, a decrease of $0.03 per Mcf from the prior year. On an absolute basis, LOE increased $3.9 million primarily due to higher transportation and gathering costs as a result of increased production, partially offset by a decrease in water management costs. LOE included $58.1 million for gathering and compression services from the Company's Gathering segment to connect Seneca’s production to sales points along interstate pipelines.

DD&A expense was $0.71 per Mcf, an increase of $0.08 per Mcf from the prior year. Absolute DD&A expense increased $14.8 million due to higher natural gas production and a higher per unit DD&A rate. The higher per unit rate was driven by an increase in Seneca's full cost pool due to a combination of higher capitalized costs and an increase in estimated future development costs related to proved undeveloped wells.

Other taxes decreased $1.6 million largely as a result of lower Impact Fees in Pennsylvania due to the decline in NYMEX natural gas prices.

Interest expense increased $2.9 million primarily due to a higher average amount of net borrowings combined with higher average interest rates.

Midstream Businesses

Pipeline and Storage Segment

The Pipeline and Storage segment’s operations are carried out by 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
	March 31,
(in thousands)	2024		2023		Variance
GAAP Earnings	$	30,737	$	23,858	$	6,879
Adjusted EBITDA	$	70,033	$	58,926	$	11,107

The Pipeline and Storage segment’s second quarter GAAP earnings increased $6.9 million versus the prior year primarily due to higher operating revenues, partly offset by higher operation and maintenance (“O&M”) and DD&A expenses.

The increase in operating revenues of $12.9 million was primarily attributable to an increase in Supply Corporation’s transportation and storage rates effective February 1, 2024, in accordance with the approved interim rates in connection with its rate case settlement, which is pending final Federal Energy Regulatory Commission approval. In addition, Supply Corporation recorded a final true-up adjustment to a surcharge for pipeline safety and greenhouse gas costs that concluded with the effective date of its rate increase, reflective of investments made in those areas.

O&M expense increased $1.8 million primarily due to an increase in personnel costs and compressor maintenance costs. The increase in DD&A expense of $1.8 million was attributable to higher average depreciable plant in service compared to the prior year.

Gathering Segment

The Gathering segment’s operations are carried out by National Fuel Gas Midstream Company, LLC’s limited liability companies. The Gathering segment constructs, owns and operates natural gas gathering pipelines and compression facilities in the Appalachian region, which delivers Seneca and other non-affiliated Appalachian production to the interstate pipeline system.

	Three Months Ended
	March 31,
(in thousands)	2024		2023		Variance
GAAP Earnings	$	28,706	$	24,334	$	4,372
Adjusted EBITDA	$	53,103	$	46,263	$	6,840

The Gathering segment’s second quarter GAAP earnings increased $4.4 million versus the prior year primarily due to higher operating revenues, partly offset by higher DD&A expense. Operating revenues increased $7.0 million, or 12%, which was the result of a $4.8 million increase in revenue from Seneca and a $2.2 million increase in revenue from non-affiliated parties. DD&A expense increased $0.7 million primarily due to higher average depreciable plant in service compared to the prior year.

Downstream Business

Utility Segment

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

	Three Months Ended
	March 31,
(in thousands)	2024		2023		Variance
GAAP Earnings	$	44,739	$	31,720	$	13,019
Adjusted EBITDA	$	78,326	$	65,820	$	12,506

The Utility segment’s second quarter GAAP earnings increased $13.0 million versus the prior year due to higher customer margins (operating revenues less purchased gas sold), lower interest expense and a lower effective income tax rate, partially offset by an increase in O&M expense.

The $14.4 million increase in customer margin for the quarter was primarily due to the impact of the base rate increase in Distribution's Pennsylvania jurisdiction. Last year, the Company received approval for a $23 million annual rate increase that went into effect in August 2023 and the ability to implement a weather normalization adjustment (“WNA”), which serves to help mitigate the impact of temperature fluctuations on usage and margin revenues (subject to a 3% deadband). Despite lower usage due to warmer weather, the Company recovered approximately $4.6 million from the Pennsylvania WNA mechanism in the current quarter. Distribution continues to benefit from a WNA mechanism in its New York jurisdiction, which helped to mitigate the impact of warmer weather on margins in the current and prior year quarters. Higher revenues from the Company’s system modernization tracking mechanisms in its New York service territory also contributed to the increase.

O&M expense increased by $2.9 million, primarily driven by higher personnel costs. These increases were partially offset by a decline in the accrual for uncollectible accounts due to a decrease in the natural gas commodity component of customer bills.

Interest expense declined $1.2 million primarily due to lower average amount of net borrowings, partially offset by higher average interest rates.

The reduction in the Utility segment's effective income tax rate was primarily driven by an increase in tax deductions related to certain repairs and maintenance expenditures as a result of updated IRS guidance published in 2023.

Corporate and All Other

The Company’s operations that are included in Corporate and All Other generated combined earnings of less than $0.1 million in the current-year second quarter, which was essentially flat compared to a combined net loss of less than $0.1 million in the prior-year second quarter.

AND SUBSIDIARIES

GUIDANCE SUMMARY

As discussed on page 2, the Company is revising its earnings guidance for fiscal 2024. Additional details on the Company's forecast assumptions and business segment guidance are outlined in the table below.

The revised earnings guidance range does not include the impact of certain items that impacted the comparability of earnings during the six months ended March 31, 2024, including: (1) after-tax unrealized losses on a derivative asset, which reduced earnings by $0.03 per share; and (2) after-tax unrealized gains on other investments, which increased earnings by $0.02 per share. While the Company expects to record certain adjustments to unrealized gain or loss on a derivative asset and unrealized gain or loss on investments during the six months ending September 30, 2024, the amounts of these and other potential adjustments and charges, including ceiling test impairments, 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 Operating Results and Adjusted EBITDA, 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 Operating Results as reported GAAP earnings before items impacting comparability. The following table reconciles National Fuel's reported GAAP earnings to Adjusted Operating Results for the three and six months ended March 31, 2024 and 2023:

Management defines 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. The following tables reconcile National Fuel's reported GAAP earnings to Adjusted EBITDA for the three and six months ended March 31, 2024 and 2023:
