Guzman y Gomez, an Australian Mexican fast-food chain, announces it is exiting the United States and closing all of its U.S. locations in Chicago-area markets. Multiple outlets report the company tells shareholders and that its U.S. restaurants cease trading effective May 22, following an earlier decision announced around May 21. The company frames the move as a response to underperformance in the U.S., with co-CEO Steven Marks saying the financial results have not been acceptable and citing challenges building the brand in a highly competitive environment.

The closures affect eight Illinois locations, and at least one source reports planned future openings in Illinois are abandoned. The company says it will keep its Australian business as a focus, and it already operates more broadly across the Asia-Pacific region, with restaurants in places including Australia, Singapore and Japan, totaling more than 260 worldwide.

Separate reporting indicates some former U.S. employees file a class action in federal court in Illinois alleging inadequate pay and notice related to the abrupt shutdown. Guzman y Gomez states it is aware of the legal action and believes it has met its obligations. After the U.S. exit announcement, the company’s shares in Australia rise sharply in response to the decision.
