Resources operates through two subsidiaries: Roanoke Gas, a regulated natural gas distribution utility established in 1883 serving residential, commercial, and industrial customers in Roanoke, Virginia and surrounding areas, and Midstream, formed to invest in interstate natural gas pipelines. Roanoke Gas maintains an integrated distribution system delivering natural gas to end-users, with the regulated distribution business accounting for over 99% of consolidated revenues; the business is highly seasonal, with approximately 76% of residential and commercial deliveries occurring during the heating season from November through March. The company operates as a regulated monopoly holding exclusive franchises in its service territories, relies on multiple interstate pipelines and storage facilities for supply, and competes indirectly with alternative energy sources including electricity, propane, and fuel oil, with revenues affected by natural gas cost changes, consumption fluctuations, and regulatory rate adjustments.
