Separation Would Create Two High-Quality Public Companies, Each With
Distinct Growth Strategies and Long-Term Value Creation Opportunities

• National Fuel’s Integrated Upstream and Gathering business would become an independent public company focused solely on its highly integrated, Appalachian upstream and gathering natural gas business.
• Post-separation, National Fuel would be a 100% rate-regulated company with natural gas utility and interstate pipeline and storage assets across Pennsylvania, Ohio, and New York.
• The separation would be effected through a tax-free distribution of shares to National Fuel shareholders.
• National Fuel expects to conclude its evaluation by October 15, 2026.

WILLIAMSVILLE, N.Y., (September 17, 2026) — National Fuel Gas Company (NYSE: NFG) (“National Fuel” or the “Company”) announced that by October 15, 2026 its Board of Directors intends to complete an ongoing evaluation of a plan to separate the Company into two independent publicly traded companies.

If pursued, upon completion of the transaction, National Fuel shareholders would own shares in both National Fuel and its Integrated Upstream and Gathering (“IUG”) business, creating two focused companies, each with significant scale, strong financial profiles, and distinct growth opportunities. As independent entities, each publicly traded company would be well positioned to deliver long-term growth and sustainable value creation for investors, customers, and employees, with the standalone businesses expected to benefit from:

• Greater capital allocation flexibility to pursue each company’s distinct growth opportunities and shareholder return priorities, supported by highly experienced leadership teams, strong balance sheets, and more tailored capital structures.
• Preserving the key benefits of integration that each business realizes today, including the capital efficiencies provided by IUG’s integrated upstream and gathering operations, and critical operating synergies that support customer affordability and commercial benefits across National Fuel’s regulated businesses.
• Clearer, more compelling, equity stories that increase visibility among relevant investors and research analysts and align each public company with its natural investor base.

“National Fuel has benefitted for many years from the strength and diversification of our integrated business model, which provided the financial capacity and cash flow generation to support significant strategic investments across the Company, including multiple transformative acquisitions since 2020,” said David P. Bauer. President and Chief Executive Officer of National Fuel. “Over that same period, the capital markets and operating environment of our regulated and non-regulated natural gas businesses have evolved meaningfully. With the expected closing of our Ohio gas utility acquisition next month, each business will be a scaled platform with distinct strategic priorities, organic growth opportunities, capital needs, and investment profiles.”

If pursued, National Fuel would separate IUG through a distribution of shares of IUG to National Fuel shareholders in a manner which would be intended to be tax-free for National Fuel and its shareholders for U.S. federal income tax purposes.

National Fuel: 100% regulated natural gas platform, with a highly-strategic, growing integrated utility and interstate pipeline and storage assets in constructive regulatory jurisdictions

If a separation is pursued, National Fuel would be a fully-regulated natural gas business with nearly $5 billion of rate base.[1] Its utility business would serve 1.1 million customers across Ohio, New York and Pennsylvania. In addition, the FERC-regulated pipeline and storage business would provide nearly 5 Bcf per day of contracted natural gas transportation capacity and 77 Bcf of fully-contracted natural gas storage services.

National Fuel operates across constructive regulatory jurisdictions, with significant long-term investment opportunities, supported by ongoing infrastructure modernization programs and increased natural gas demand accelerating the need for new pipeline and storage infrastructure. Together, these dynamics support continued investment in existing pipeline systems, as well as the ongoing execution of transmission and storage expansions to support growing demand.

National Fuel would benefit from a strong balance sheet and investment grade credit metrics expected to be in line with some of the strongest in the utility sector, with no need to raise incremental equity capital expected over the next five years based on current capital plans.  This would provide the company with significant financial flexibility to fund its growth plans and position it to execute on its long-term growth opportunities.

Integrated Upstream and Gathering: A premier, integrated Appalachian natural gas business with high-quality assets, and best-in-class inventory depth and capital efficiency trends

If a separation is pursued, IUG will be a leading integrated, low-cost, upstream natural gas business, with approximately 1.2 million total net acres in Appalachia and approximately 1.1 Bcf per day of net natural gas production. IUG owns significant integrated gathering assets that transport the vast majority of its production, providing greater operational control, cost certainty, and alignment across its operating footprint. With approximately 5 Tcf of natural gas reserves and more than 40 years of prospective Marcellus and Utica development inventory, IUG would be well positioned to grow production, extend its track record of operational improvement, and create long-term value through disciplined capital allocation.

Since transitioning its development program to the Eastern Development Area in 2023, IUG has delivered industry-leading capital efficiency improvements of approximately 25%, enabling IUG to generate increased production and free cash flow per dollar invested while enhancing potential shareholder returns. Combined with its integrated gathering platform and portfolio of firm transportation capacity that provides access to premium markets, IUG would be expected to maintain a differentiated cost structure and market access advantages that support long-term value creation.
