Casey's General Stores has agreed to acquire 20 convenience stores in Oklahoma from ASAP Energy, along with the company's wholesale and commercial fuels and lubricants businesses and other related assets, representatives from both companies confirmed to C-Store Dive.

The acquisition marks Casey's second purchase of 20 or more convenience stores this summer as the retailer advances its plan to add at least 400 locations to its network over the next three years. In early August, Casey's agreed to acquire 24 locations from Texas-based convenience retailer Pak-A-Sak.

A Casey's spokesperson declined to share an estimated closing date for the transaction.

"The attractive mix of high-quality convenience retail stores, and wholesale and commercial fuels and lubricants businesses align strongly with Casey's growth strategy," the Casey's spokesperson said in a statement. "We look forward to the next steps in this transaction and welcoming the employees to the Casey's family."

The deal does not include ASAP's Lucille's Hotel, the Lucille's Restaurants, Ricks Boots and Outfitters or its Centurion Land Development arm, according to representatives from both companies.

While organic growth remains a key part of Casey's expansion strategy, the retailer continues to use bolt-on acquisitions to accelerate store growth. The ASAP deal moves Casey's closer to 3,000 convenience stores in the U.S., a milestone only surpassed by 7-Eleven and Circle K. It also expands the retailer's footprint in Oklahoma, where Casey's operated nearly 150 locations as of this summer.

ASAP Energy, founded in 1979, is the latest independent retailer to exit the industry as economic headwinds continue to pressure smaller convenience store owners.

In an announcement shared with the Weatherford Daily News and posted on Facebook, ASAP Energy owners Rick and Sheila Koch said the sale aims to give employees "more opportunities for professional growth, more resources, and more possibilities for long-term success."

"We believe Casey's can provide those opportunities," the Koches said. "Casey's is a company where people can build long, rewarding careers, and we see this as an incredible opportunity for our Team members to grow alongside a thriving brand."

For marketers tracking consolidation in convenience retail, the deal signals that Casey's M&A engine will keep absorbing regional independents as it pushes toward its 400-store, three-year growth target.
