As a report by Bloomberg explains, the impending domestic closures are part of Subway's plan to expand its restaurant empire abroad. The closings also shouldn't come as a total shock, as the chain has been reducing its footprint in the past couple years, shuttering some 800 locations alone in 2016.
While Subway plans to launch even more stores outside the country, it's worth noting that its sales in the US have fallen 4.4% in the last year. To give some perspective, in that same timeframe McDonald's has seen a 3.4% increase in sales, per the report. Still, Subway remains the largest in terms of global store count by quite a large margin, with nearly 26,000 locations in the US alone compared to Mickey D's, which boasts roughly 14,000 US outposts. Evidently, the shutdowns are part of Subway's grand plan to focus on improving the locations that will remain open.
