Business Description

Portillo’s Inc. (the “Company") was incorporated as a Delaware corporation on June 8, 2021, for the purpose of facilitating an initial public offering ("IPO") and other related transactions in order to carry on the business of PHD Group Holdings LLC and its subsidiaries (“Portillo’s OpCo”). The Company became the sole managing member of Portillo’s OpCo and operates and controls all of the business and affairs of Portillo's OpCo. As a result, the Company consolidates the financial results of Portillo's OpCo and reports a non-controlling interest representing the economic interest in Portillo's OpCo held by the other members of Portillo's OpCo (the "pre-IPO LLC Members"). Portillo’s Inc. Class A common stock trades on the Nasdaq under the symbol "PTLO." Unless the context otherwise requires, references to "we," "us," "our," "Portillo's," the "Company" and other similar references refer to Portillo's Inc. and its subsidiaries, including Portillo’s OpCo. As of the fiscal year ended December 28, 2025 ("fiscal 2025"), we owned and operated 102 restaurants across 11 states, including a restaurant owned by C&O Chicago, L.L.C. ("C&O") of which we own 50% of the equity . As of December 28, 2025 , the Company owned 95.4% of Portillo's OpCo and the pre-IPO LLC Members owned the remaining 4.6% of Portillo's OpCo. The Company entered into a joint venture agreement to develop and operate a restaurant at the Dallas-Fort Worth International Airport ("DFW") which is expected to commence operations in 2026. The Company holds a 65% ownership interest in AP Dogs, LLC ("AP Dogs") and has day-to- day operational and managerial control over its business and affairs. Accordingly, the Company consolidates the joint venture and reports a noncontrolling interest representing the economic interest in AP Dogs held by the other partner. Overview of Portillo's Portillo’s serves iconic Chicago street food in high-energy, multichannel restaurants designed to ignite the senses and create memorable dining experiences. Since our founding in 1963 in a small trailer that Dick Portillo called “The Dog House,” we have grown to become a treasured brand with a passionate (some might say obsessed) nationwide following. Our diverse menu features all-American favorites such as Chicago-style hot dogs and sausages, Italian beef sandwiches, char-broiled burgers, fresh chopped salads, crinkle-cut fries, homemade chocolate cake and our signature chocolate cake shake. We create a consumer experience like no other by combining the best attributes of fast-casual and quick-service ("QSR") concepts with an exciting energy-filled atmosphere in a restaurant model capable of generating tremendous volumes. Nearly all of our restaurants were built with double lane drive-thrus and have been thoughtfully designed with a layout that accommodates a variety of access modes including dine-in, carryout, delivery and catering to quickly and efficiently serve our guests. We believe the combination of our craveable food, multichannel sales model, dedication to operational excellence, and distinctive team member-driven culture gives us a competitive advantage. Our business, including many of the elements described below, is subject to certain risks that may materially and adversely affect our ability to achieve our desired outcomes.
