Hastings Equity Partners said March 28 it acquired Midland, Texas-based Cactus Fuel LLC for an undisclosed amount.

Cactus Fuel recently expanded into New Mexico and is in the process of opening additional locations to further increase its reach, said Jimmy Tindol, CEO of Cactus Fuel, in a statement.

"We are very excited to partner with Hastings and look forward to being able to expand and enhance our service offering to our customers," Tindol said.
