What National Fuel Gas Company told the SEC could break it.
National Fuel is a geographically concentrated integrated gas company: its Integrated Upstream and Gathering segment — 46% of its net property, plant and equipment — sits primarily in the Appalachian Marcellus region, while its utility serves western New York and northwestern Pennsylvania, so its fortunes are tied to those areas' geology and economies. Within that, one customer of its upstream and gathering business provided about $258 million, or 11.3%, of consolidated fiscal-2025 revenue, a meaningful single-customer concentration. And state climate policy weighs on its long-term demand: aggressive decarbonization and electrification measures, particularly in New York, threaten the future of its gas-distribution utility.
3 self-disclosed vulnerabilities, pulled from its own filings, each in the company’s words, with the source. This is the risk register almost nobody reads.
