Portillo’s Announces Plan to Further Strengthen Board Through Cooperation Agreement with Engaged Capital

CHICAGO, April 28, 2025 (GLOBE NEWSWIRE) — Portillo’s Inc. (“Portillo’s” or the “Company”) (NASDAQ: PTLO), the fast-casual restaurant concept known for its menu of Chicago-style favorites, today announced that it has entered into a cooperation agreement with Engaged Capital, LLC (“Engaged Capital”). As part of the cooperation agreement, Portillo’s and Engaged Capital will cooperate to identify a new director with recent and relevant restaurant operating experience to be appointed to the Portillo’s Board of Directors.

“We are pleased to have reached this agreement with Engaged Capital,” said Michael A. Miles, Jr., Portillo’s Chair of the Board. “The Board is committed to overseeing decisive action to drive traffic, improve margins and deliver industry-leading unit economics for shareholders. We appreciate the partnership with Engaged Capital to identify a new director to bring additional expertise to our Board, in addition to the role they played in introducing us to Jack Hartung, who was appointed to the Board in January.”

“Although we wish him well in his new role, we were disappointed it resulted in one of our nominees having to withdraw from this process. We are pleased to have been able to work constructively with the Board on an alternative solution for adding a highly qualified director with restaurant operating expertise,” said Glenn W. Welling, Founder and Chief Investment Officer of Engaged Capital. “Portillo’s is one of the most iconic brands in the restaurant industry as demonstrated through industry leading AUVs in and outside of Chicago. Through the actions being taken to shrink restaurant size, drive sustainable same store sales, and improve restaurant margins, we continue to see a significant opportunity to create as much value for shareholders as Portillo’s delivers to their customers.”

Engaged Capital has also agreed to certain customary standstill and voting agreements. The cooperation agreement between the Company and Engaged Capital will be filed on a Form 8-K to be filed with the Securities and Exchange Commission.
