NATIONAL REPORT — The Convenience Store News Top 20 Growth Chains list is back, and this year, El Paso, Texas-based Western Refining Inc. joins the ranks atop the annual ranking.

The CSNews Top 20 Growth Chains report is based on store count figures provided by TDLinx, a service of Nielsen. This is the sixth year that CSNews has partnered with TDLinx to identify the c-store retailers that added the most convenience stores in the past year.

The period analyzed was January 2016 to January 2017. Wherever possible, the TDLinx numbers were confirmed by the companies. TDLinx defines a convenience store as a store that includes a broad merchandising mix, extended hours of operation, and a minimum of 500 SKUs. Fueling stations with small kiosk stores do not meet the official definition and thus are not reflected in TDLinx’s figures.
