Star Group, L.P. operates as a leading retail distributor of home heating oil and propane, serving residential and commercial customers primarily across the Northeast and Mid-Atlantic United States. The company's business model centers on the delivery of heating fuels, complemented by a robust service division that installs, maintains, and repairs heating, ventilation, and air conditioning (HVAC) equipment. Revenue is primarily generated from the sale of home heating oil and propane, which accounts for approximately 61% of total sales. Other petroleum products, mainly diesel and gasoline sold on a delivery-only basis, contribute around 21% of revenue, while installation and repair services make up the remaining 18%. Star Group serves over 400,000 full-service residential and commercial customers, alongside tens of thousands of delivery-only customers. The company's competitive position is bolstered by its scale, operating as the largest retail distributor of home heating oil in the U.S. with a market share exceeding 5.5%. Originally structured as a master limited partnership (MLP) in 1995 under the name Star Gas Partners, L.P., the company elected to be treated as a corporation for U.S. federal income tax purposes in 2017 and rebranded to Star Group, L.P.
