Stonepeak has acquired The All-Gas Companies, a leading provider of propane, compressed gases, and related services across Connecticut and southern New England, for an undisclosed amount. This transaction marks Stonepeak’s complete purchase of the long-standing family-owned business, bringing Allgas under new ownership.
The All-Gas Companies, which include The ALL-GAS & Equipment Company and The Aero ALL-GAS Company, have served the region for four generations since their establishment in 1941. Their mission centers on providing reliable service and high-quality products. Allgas offers comprehensive residential and commercial propane delivery and installation services throughout Connecticut, handling tanks from small grill sizes to thousands of gallons for bulk fills. Additionally, The Aero ALL-GAS Company supplies a wide range of compressed gases, including complex medical mixtures, industrial gases, and helium, ensuring purity for critical applications in healthcare and various industries. They also provide dry ice, welding equipment, and cryogenic installations.
This acquisition is strategically significant for Stonepeak, providing it with an established, diversified platform in the essential energy and gas distribution sector. Allgas's deep regional roots, broad service offerings, and strong customer relationships present a robust operational base. The combination is expected to create synergies by leveraging Allgas's operational expertise and market presence with Stonepeak’s resources, potentially enhancing service capabilities and expanding market reach.
Looking ahead, the combined entity aims to maintain Allgas's tradition of customer satisfaction and high-quality service while exploring opportunities for growth and efficiency under Stonepeak’s ownership. The focus will remain on delivering essential propane, compressed gas, and related solutions to residential, commercial, and medical customers across its service areas.
