Arko Corp., the parent company of convenience-store retailer GPM Investments, has named former Murphy USA CFO Galagher Jeff as its new executive vice president and CFO, effective immediately, the company announced Monday. Jeff succeeds Robb Giammatteo, who departed the convenience-store chain in October to pursue a new opportunity outside the channel.
Prior to his tenure at Murphy USA, Jeff (pictured below) spent nearly 15 years in senior and executive finance roles with retailers including Dollar Tree, Advance Auto Parts and Walmart. Before that, he spent a decade-long career in finance and strategy consulting at organizations including KPMG and Ernst & Young.

“Mr. Jeff’s tenured career in strategy and finance in multiple leadership roles, and his convenience store and retail experience, will augment an already strong Arko team,” said Arie Kotler, chairman, president and CEO.
Kotler said that Jeff’s expertise will be instrumental in advancing the growth of the company.
“I am honored to join the Arko team,” said Jeff. “I see tremendous opportunity for the company as it continues to execute on its multi-year transformation plan, supported by its ongoing channel optimization work and execution of organic growth initiatives.”
In the announcement, Kotler also thanked Jordan Mann, who served as interim CFO following Giammatteo’s departure from the company, for “successfully providing a seamless transition for the company during our CFO search and supporting Galagher as he joins the Arko family.”
Mann serves as the Richmond, Virginia-based company’s senior vice president of corporate strategy, capital markets and investor relations.
