Portillo's CEO Michael Osanloo resigns unexpectedly

In the United States, on September 23, 2025, Portillo's announced the immediate resignation of its CEO, Michael Osanloo. Osanloo had served as the president and CEO of the well-known fast food chain, which is particularly popular in Chicago, until his resignation was made public without prior notice. This sudden departure has drawn attention due to the company's recent changes in strategy, which include the cancellation of a pilot program that was testing a breakfast menu in Chicago. Osanloo expressed gratitude for his time with the company, stating it was one of the great honors of his career. Following Osanloo's resignation, the Board of Directors appointed Michael Miles, Jr. as the interim CEO. Miles has a history with the company, having previously served as Portillo's interim CEO from 2014 to 2015 and currently holds the title of Chairman of the Board since 2014. He has also held executive positions at other major companies, including Staples and Pizza Hut. As part of the leadership transition, Osanloo will work as a special advisor to Miles for 90 days, which indicates that the company is focused on a seamless leadership transition. Portillo's operates 90 restaurants across 10 states and is known for its unique fast-casual dining experience. The company's recent strategic efforts reflect its ambition for growth and further development in a competitive fast-food market. The leadership change and strategy adjustments may suggest the firm is pursuing a stronger position amid market dynamics. A search is underway for a permanent CEO to lead Portillo's into its next chapter. The departure of Osanloo might impact the company's direction and operational approach moving forward, especially as it aligns itself with an evolving market and customer preferences. The operational framework and strategic initiatives under new leadership will be pivotal in determining the company's future performance in the fast-food industry.
