Star Group, L.P. is a Delaware limited partnership that operates as a home heating oil and propane distributor and service provider in the Northeast and Mid-Atlantic U.S., with one reportable segment. As of September 30, 2025, it served about 406,400 full service and 63,200 delivery-only heating oil and propane customers, plus 27,700 motor fuel and other petroleum product customers. In 2025, sales were about 63% from home heating oil and propane, 18% from other petroleum products, and 19% from equipment installation, repair and related services.
The company distributes primarily through Petro Holdings, Inc., and finances operations with a $210 million senior secured term loan and a $400 million revolving credit facility (rising to $475 million in the heating season), both due in 2029. During fiscal 2025 it acquired one heating oil and three propane businesses for approximately $80.5 million in cash. Star highlights risks from wholesale fuel price volatility, supply constraints, customer attrition, and expanding climate and environmental regulations that aim to reduce fossil-fuel use, particularly in key states such as New York and Massachusetts.
