National Fuel Gas Company Continues Peer Leading Sustainability Initiatives Through EO100TM and MiQ Programs

National Fuel Gas Midstream Company, LLC (Midstream), the Gathering segment of National Fuel Gas Company (NYSE: NFG) (National Fuel or the Company), has been re-verified under Equitable Origin’s EO100™ Standard for Responsible Energy Development. The re-verification independently confirms that Midstream continues to adhere to the performance obligations earned under Midstream’s initial EO100™ certification, achieved in 2023, while also verifying Midstream’s commitment to the continuous improvement plan established upon initial certification. During the re-verification process completed in October 2024, Midstream was awarded an “A-” grade, with Midstream recognized as the first entity in the EO100™ framework to improve two grades following initial certification. 100% of Midstream’s natural gas gathering system assets were subject to a series of rigorous performance targets that fall under the five principles of the EO100™ Standard, including corporate governance and ethics; social impacts, human rights and community engagement; Indigenous Peoples' rights; occupational health, safety and fair labor standards; and environmental impacts, biodiversity and climate change. Midstream was the first gathering or midstream company and second National Fuel subsidiary to earn EO100™ Standard certification, joining Seneca Resources Company, LLC (Seneca Resources), which previously achieved certification of 100% of its natural gas production under the EO100TM Standard in 2021.

Furthermore, Seneca Resources, NFG’s Upstream segment, announced it has been re-certified by MiQ and was awarded an “A” grade (the highest certification level available) for 100% of its Appalachian natural gas production assets, which produce over 1 billion cubic feet of gross production per day. The MiQ certification focuses on three emissions criteria, including: methane intensity, practices to manage methane emissions, and emissions monitoring technology deployment.

“The EO100™ and MiQ re-certifications that Midstream and Seneca achieved demonstrate our dedication to sustainability through our proactive emissions reduction efforts and best practices,” said Justin Loweth, President of Seneca Resources Company, LLC and National Fuel Gas Midstream Company, LLC. “I am proud of the work our team has done to not only achieve these accolades, but their commitment to build upon these certifications, engraining these principles and practices into our everyday culture.”
