Seneca Resources Output Falls 7% in Fourth Quarter
National Fuel Gas Company's Seneca Resources unit reported a fiscal fourth-quarter production decline and plans a 2027 spin-off as a separate public company.
Updated on Nov. 6, 2026 in Oil and Gas

National Fuel Gas Company reported that Seneca Resources' fiscal fourth-quarter production declined 7%, totaling 104 Bcf, or about 1.13 Bcf/d. Full-year fiscal 2026 output reached 419.5 Bcf, below lowered guidance, even as the parent company's adjusted earnings rose 9%.
Why it matters
The shortfall reflects operational setbacks in Pennsylvania's Marcellus and Utica shale plays, which shape the company's production outlook heading into its planned separation of Seneca. Investors and industry watchers are tracking whether the unit can return to growth as management projects.
Seneca Resources produced 104 Bcf in the fiscal fourth quarter, about 1.13 Bcf/d, down 7%, and 419.5 Bcf for full-year fiscal 2026, below lowered guidance. Parent National Fuel Gas Company's adjusted earnings rose 9% over the same fiscal year.
The players
National Fuel Gas Company
A Buffalo-based energy holding company whose subsidiaries span natural gas exploration, production, pipeline, and utility operations, and which is separating its Seneca Resources upstream unit.
Seneca Resources
The upstream natural gas exploration and production subsidiary of National Fuel Gas Company, focused on Appalachian Basin shale plays including the Marcellus and Utica formations.
The details
Management attributed the decline to a dud Marcellus pad in Lycoming County, mediocre Upper Utica results, and frac interactions, also known as frac hits, between Lower Utica wells in Tioga County. Seneca expects fiscal 2027 production to be roughly flat, with growth resuming in fiscal 2028.
Timeline
Fiscal fourth quarter, July through September 2026: production drop reported.
Fiscal year 2026, ending September 30, 2026: full-year output came in below lowered guidance.
Fiscal 2027: Seneca production expected roughly flat.
Second half of 2027: planned spin-off of Seneca Resources as a separate public company.
Fiscal 2028: Seneca expects production growth to resume.
Market Landscape
Seneca's shortfall illustrates the well-level variability that has marked the Appalachian Basin's Marcellus and Utica shale development since the region's rapid expansion. The planned spin-off signals that National Fuel Gas is separating its upstream growth profile from its regulated utility and pipeline businesses.
Shareholders of National Fuel Gas Company will eventually hold stock in a separately traded Seneca Resources if the spin-off proceeds as planned. Seneca's flat fiscal 2027 production outlook means near-term volume growth will not contribute to the parent's results until fiscal 2028.
The takeaway
Production swings at individual shale pads can move a company's upstream results even when overall corporate earnings grow, so tracking unit-level output alongside consolidated figures gives a clearer picture of performance.
What happens next
National Fuel Gas Company plans to complete the spin-off of Seneca Resources as a separate public company in the second half of 2027.
