 Portillo's Inc. Form 10-K | 1

 ITEM 1. BUSINESS

 Portillo's Inc. (the "Company") was incorporated as a Delaware corporation on June 8, 2021, in connection with our initial public offering in October 2021 ("IPO") and related reorganization transactions (collectively, the "Transactions") in order to carry on the business of PHD Group Holdings LLC and its subsidiaries ("Portillo's OpCo"). Following the consummation of the Transactions on October 20, 2021, the Company became the sole managing member of Portillo's OpCo and now 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.

 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 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. For a more in-depth discussion of such risks, see Part I, Item 1A, "Risk Factors."

 As of December 29, 2024, we owned and operated 94 restaurants across 10 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 29, 2024, the Company owned 85.6% of Portillo's OpCo and the pre-IPO LLC Members owned the remaining 14.4% of Portillo's OpCo.

 Our Story

 We relish the opportunity to create lifelong memories by igniting the senses with unrivaled food and experiences.

 An Iconic and Beloved Brand with Obsessed, Lifelong Fans. We capture the hearts, minds and stomachs of our guests with every meal. Our menu features something for everyone and appeals to a broad demographic, which enables our restaurants to thrive and generate strong and balanced volumes across multiple dayparts, weekdays and occasions. Guests cake shake their way in for our Chicago-style hot dogs, Italian beef sandwiches, char-broiled burgers, cheese fries, fresh salads and famous chocolate cake.

 Energetic Restaurant Atmosphere that Engages the Senses. While our operating model is focused on getting delicious, made-to-order food to our guests quickly, we believe our atmosphere makes the experience more than a delicious meal. When guests walk into a Portillo's, they get an experience completely different than a typical chain restaurant visit. Our restaurants engage all the senses to create a fun, relaxed and memorable occasion.

 Our dining areas evoke nostalgia and local influences. No two Portillo's are alike. Each of our restaurants has its own themed d cor, ranging from a 1930s prohibition motif to a 1950s diner to a 1960s flower-power bus, as well as a retro automotive garage theme. The period music ties to the theme, from ragtime to doo wop to disco. No detail is too small, be it lighting, signage or even the stars subtly sparkling on the ceiling. Each restaurant also draws design elements from the local community. The layouts create comfortable spaces for individual diners, families, large groups, and even wedding parties.

 Beyond the space itself, we believe the energy of Portillo's is unique. Our guests can see into our open kitchens, where their meals are prepared right before their eyes. The smells of burgers broiling, french fries frying, and beef simmering emanate from the kitchen. Each completed meal is announced with a fun rhyme ("Number two, we got you"; "Number seven, welcome to Portillo's heaven"). But the most important element of the energy is the enthusiasm of the scores of guests who are all excited to be there and enjoying their Portillo's. We want every guest that visits to leave with good memories, a satiated appetite and a desire to return.

 Our Strategy

 Our strategic plan is comprised of four pillars, which guide our short-term objectives and form the basis for growth:

 • Run World-Class Operations
 • Innovate and Amplify the Portillo's Experience
 • Build Restaurants with Industry-Leading Returns
 • Take Great Care of Our Teams

 We believe that by focusing on the components of each of these simple, but focused, strategies we feed a virtuous cycle in which we take care of our team members, our team members take care of our guests, and our guests reward our shareholders.

 Run World-Class Operations. We believe that delivering a consistently exceptional guest experience, including having guests try our delicious food is one of the most effective forms of marketing. By running world class operations, we will fuel Portillo's same-restaurant sales growth. The core tactics we use in this strategy are:

 • Flexing our Multichannel Muscle: Portillo's aims to offer industry-leading experiences across our traditional sales channels, while continuing to grow and innovate in growth sales channels. Dine-in provides the best Portillo's experience, so we strive for our dine-in experience to represent the heart of Portillo's and our company values of Family, Greatness, Energy, and Fun. In our drive-thru, we strive to maintain top performance in the industry across speed, service, and accuracy. In new markets, we show new guests the value and efficiency of our drive-thrus. In our sales channels of digital pickup, delivery, and catering we have made great strides operationally that will allow us to win additional market share.

 • Greatness in Drive-Thru: Portillo's pioneered a winning drive-thru model beginning in the 1980s, combining speed and hospitality via outside order takers, food runners, and multi-lane drive-thrus. Our teams are focused on continuously improving and innovating the drive-thru experience to improve throughput and order accuracy. All new restaurants are opened with drive-thru doors to aid our runners and improve the guest experience. We have also started a camera vision test in select restaurants to provide operators with real-time actionable insights.

 • Unrivaled Value in Fast Casual: Experience, service, and food quality define value in our brand, but maintaining a strong price point remains a high priority given how broadly we compete in the restaurant industry. Our teams consistently monitor price points across many categories and occasions that are relevant to our guests. To succeed moving forward, we will continue our pricing strategy combined with a focus on operational excellence and aim to remain an unrivaled value compared to fast casual competitors.

 Innovate and Amplify the Portillo's Experience. We believe one of the most effective ways to market Portillo's is by having people experience our food firsthand. Our efforts in field marketing, social media, digital engagement, advertising, and menu innovation support the following aspirations:
 • Craveable & Fresh For Everyone: Our industry-leading AUVs are bolstered by a broad menu that offers something truly craveable for everyone. We constantly research our menu, our guests, and our competition to keep the menu fresh and relevant while also balanced to ensure operational efficiency. For example:
 In 2024 we launched two new salads, our Chicken Pecan Salad with Bacon to appeal to health-driven foodies and our Spicy Chicken Chopped Salad, a new twist on a Portillo's classic to increase visits from longtime fans. Both items added excitement and variety to the menu while enhancing average ticket. To celebrate the launch, we unveiled a limited-time brown paper bag with green stripes. Similar to its predecessor, the new bag is 100% recyclable, bleach-free, and is made from fibers certified by the Sustainable Forestry Initiative. We believe this purposeful menu innovation drives increased guest frequency and reinforces the everyday value proposition that is key to our success.
 We enhance our menu with seasonal shakes and specialty cakes, offering something special throughout the year. In Fall 2024, we launched our first new cake flavor in 20 years: the Salted Caramel Spice Cake. To celebrate, September 2024 became "Spice-Tember", in which we sold our new cake for $1 a slice with the purchase of an entree. In October 2024, we also partnered with former Chicago Bear, Anthony "Spice" Adams, to create energetic and entertaining content, spotlighting the Salted Caramel Spice Cake in a fun and engaging way.

 • Local & Experiential: Whether it's an influencer night for a launch of new menu items, hosting a community fundraiser, partnering with local and national sport teams, or a visit from our mobile food truck, lovingly dubbed "The Beef Bus," we aim to create lifelong memories via grassroots field-marketing efforts. In each of our markets we employ field marketing managers who partner with local restaurant General Managers to personalize a marketing plan and introduce Portillo's to the local area. We believe this approach creates a personal and emotional connection with the communities in which we operate and creates incremental returns on our marketing investments. We use a full suite of communication channels, such as email, X (formerly known as "Twitter"), Instagram, TikTok, Facebook, and other platforms to spread our message to different customer segments. When a compelling opportunity arises, Portillo's also utilizes traditional advertising in Chicagoland to drive frequency and outside Chicagoland to drive trial and awareness. Below are a few advertising and marketing highlights of the fiscal year ended December 29, 2024 ("fiscal 2024"):
 We launched an ad campaign in Arizona in the first quarter of 2024 to drive trial and awareness.
 In April, we re-launched our Famous Five combo meal menu that features a classic entree, side, and drink.
 We re-launched our advertising in the Chicagoland market. Our comprehensive advertising campaign coincided with the start of the NFL season. We continued the theme of "Portillo's. It always sounds good." The ad campaign consisted of commercials, billboards, and partnerships with several digital media outlets, such as Barstool Sports, to reach our guests across the Chicagoland area.

 • Digitally Engage Guests: Our guests increasingly interact with Portillo's in the digital space, whether engaging with us on social media, learning about us through digital advertising, or placing an order on our app or in one of our new self-order kiosks. Kiosks have been a resounding success, adding incrementality to the check and providing a stellar guest experience. In 2025 we are launching our "Portillo's Perks"TM loyalty program to drive and reward repeat visits and make the Portillo's experience even more engaging for our longtime fans.

 Build Restaurants with Industry-Leading Returns. En route to our current goal of over 900 US restaurants (see "Our Growth" below for more details) we continue to innovate our business model in ways that meet a rapidly changing economic and consumer environment while delivering outstanding returns to investors.

 • Best-In-Class AUVs: The average Portillo's generates per-restaurant sales that sit far atop the fast-casual and limited-service restaurant segments. A key element of our strong restaurant-level adjusted EBITDA margin, we aim to keep our average unit volumes ("AUVs") high via discerning market and site selection.

 • Optimize Capital Investments: We are continuously refining our restaurant prototypes while investing in existing restaurants to drive great guest experiences and great returns. In the past, some of our restaurants were over 10,000 square feet and had 105-foot production lines. Restaurants built in 2023 were approximately 7,700 square feet with a 65-foot production line all while capable of generating an equivalent AUV. In 2024 we opened two restaurants with our "Restaurant of the Future" prototype, a 6,250 square foot restaurant with a 47-foot production line that is more efficient to build and also better reflects the way consumers interact with our brand today. Our teams will continue to make strides in this space to further reduce our build costs and achieve attractive returns.

 • Scale Quickly: Having scale in markets creates brand awareness, drives sales, and expands profit margins. We aim to have minimum efficient scale (6-8 restaurants) in new markets within 24 months of our first opening. Our entry into the Dallas-Fort Worth, Texas market is a great example of this strategy, where our first restaurant opened in January of 2023 and our 7th restaurant opened in December 2024.

 • Replicable Processes: Scaling quickly requires standardizing leases and deal structures, leveraging select general contractors and vendors, and standardizing the base of our prototypes. With these scalable and predictable processes, we will be able to adhere to or beat a target 18-month development cycle time and be more meticulous in our market penetration strategies.

 Take Great Care of Our Teams. Our team members put in the hard work to help create happy guests (and value for our shareholders). To attract, train, retain, and engage the best team members we strive to offer great rewards, talent management, learning, development, and people technology programs that drive obsession with Portillo's. Identifying, developing, and placing internal talent fuels our increasing rate of growth.

 • Meaningful Work Environment: We cultivate an environment where every individual feels valued, empowered to share ideas, and actively engaged in their work. We prioritize clear expectations and communication while providing our team with the necessary tools and resources for success. This creates a work environment that enhances overall experience and productivity for our team members resulting in happy guests and industry-leading retention.

 • Total Rewards that Matter: Delivering competitive compensation, benefit, and recognition programs attracts great talent and helps create happy, long-term team members. We will continue to evolve rewards, specifically those that differentially drive retention. We continuously evaluate our wages with the goal of paying above market in our restaurants.

 • Igniting Talents and Careers: Identifying, nurturing, and developing talent is critical to our growth strategy as we aim to open each new restaurant with an experienced Portillo's manager. Our Ignite development programs identify high potential individuals to become hourly supervisors, restaurant managers, assistant general managers ("AGMs"), general managers ("GMs"), and multi-unit Market Managers and develops their skills via off-site leadership development and in-field shoulder-to-shoulder coaching. These programs demonstrate a clear and enticing career path for our team members and keeps our talent pipeline robust. At the end of 2024, we have 70+ team members in-line for future restaurant management positions.

 • Enhanced Digital Workplace Experience: Just as consumers engage with their favorite brands digitally so do team members. In 2024 we launched Portillo's Connect, an all-in-one communications platform that allows team members and managers to receive critical communications, engage with one another via social media, access resources such as recipes and standard operating procedures, and much more. This strategy allows individuals to connect with the people they work with, support their growth and development, and enhance their well-being and sense of belonging.

 Our Growth

 We are in the early stages of our nationwide growth plan, with 94 locations across ten states at the end of fiscal 2024, including C&O. In fiscal 2024, we opened 10 new restaurants, representing 12% unit growth. Over the long term, we aim to increase our number of restaurants by approximately 12% to 15% annually. Our near-term restaurant growth strategy is focused on leveraging our proven unit economic model primarily in markets outside Chicagoland with favorable macro-economic tailwinds where we already have a presence. Particularly, our current focus is in the Sunbelt, with growth across markets in Arizona, Texas, and Florida. We are also actively sourcing sites in Georgia, Colorado, Nevada, North Carolina, and South Carolina. Simultaneously, we will continue to fill-in Chicagoland and adjacent markets as opportunities come available. Over the past year, our development function has made great strides in creating scalable, repeatable processes, giving us confidence as we grow nationally.

 Based on a whitespace analysis prepared in partnership with a third-party vendor in 2023, we believe we have a substantial runway for growth, including, a long-term opportunity to grow to more than 900 restaurants domestically and we are well-positioned for global growth in the future. Of the 900 domestic restaurants- to which we aspire, we currently project 800 to be full-scale restaurants and 100 to be pick-up/walk-up models. We see these company-operated full-scale restaurants as our largest opportunity moving forward. At the same time, we continue to evaluate innovative operating models. On the heels of opening a third Portillo's Pickup location, we will continue to analyze where these, and other operating models such as urban walk-ups, airports and campuses, fit within our growth trajectory to add sales, manage cannibalization, and provide additional pipeline growth.

 Our Team – Human Capital Management

 Our team member base, as of December 29, 2024, consisted of 8,512 team members. This included 216 Restaurant Support Center ("RSC") team members, 482 restaurant managers, AGMs, and GMs, and 7,714 restaurant hourly team members in positions such as crew chief, training lead, food production and guest services. We also have 88 hourly team members, which also includes crew chiefs, and 12 salaried team members, which includes managers and senior managers, at our commissaries. Our team members are not covered by any collective bargaining agreements. Certain of our team members at our commissaries in Addison, IL and Aurora, IL voted on April 13, 2023 and April 30, 2024, respectively, in favor of being represented by a union. We filed objections to the 2023 election with the National Labor Relations Board ("NLRB") on April 19, 2023, asserting that the union and its agent's promises prevented a free and fair election. We are actively pursuing litigation to set aside the election results. We filed an objection to the 2024 election with the NLRB on May 7, 2024, asserting that the promises made by the union and its agents prevented a free and fair election. Although we have not received other petitions to unionize, it is possible that additional team members may seek to be represented by labor unions in the future. See our risk factor "Matters relating to employment and labor law could have a material adverse effect, result in litigation or union activities, add significant costs and divert management attention" identified in Part I, Item 1A of this Form 10-K.

 Our Board of Directors and Board committees provide oversight of certain human capital programs. The Compensation Committee, with input from management and an independent third-party compensation consultant, has responsibility for administering and approving compensation, including our incentive and equity-based plans for executive officers. We discuss talent and succession plans annually for key positions and levels including the executive team. We have implemented and are executing several initiatives to support our objectives to attract, develop and retain team members, including at the executive level.

 Values-Driven, People-Centric Culture. We believe this reflects our conviction that our people are the Heart of Portillo's. We aim to attract, hire and develop great people who turn their obsession for our brand into a profession. Our team members are passionate about our food, love our guests, and call their teammates "family." We are proud that Portillo's family reflects the communities in which we operate. We strive to foster a sense of individuality, safety, support, belonging and fairness through our people-centered practices in talent acquisition, talent management, total rewards and learning and development.

 Our people-centric culture is centered on working together to create a fun, energetic atmosphere while living our values:

 Family

 We work together to make everyone feel at home, and we step up when someone needs help.

 Greatness

 We are obsessed with being the best and work hard to continuously improve. Our greatness is rooted in Quality, Service, Attitude and Cleanliness ("QSAC").

 Energy

 We move with urgency and passion, while maintaining attention to detail.

 Fun

 We entertain our guests, we connect authentically, and we make each other smile.

 We believe these values extend beyond our restaurants, to every Portillo's team member. Living these values reinforces the culture we're proud to have built. It's why we are passionate about attracting and selecting team members who are aligned with our purpose and values, as well as why we established an employee value proposition centered around culture. It's also why our team members are among our best ambassadors and why we've seen success with our Relish Referrals team member referral program.

 Leadership Development. We provide a full spectrum of resources, from skill building to leadership development, in the organization. Our philosophy is to develop people to be ready before a position is open, as opposed to waiting for a position to be open and then training them. We view this investment as fundamental to our growth, building a pipeline of leaders for our future.

 We are committed to continuing education and providing ways for individuals to build their talents. Portillo's has invested in Linked In Learning for all hourly crew chiefs, restaurant management, commissary crew chiefs and RSC team members. This initiative allows us to give additional learning and development opportunities above and beyond job skills or initial leadership development. We have also partnered with Better Up Coaching to give our leaders feedback and opportunities for personal growth.

 Our leadership program, Ignite, continues to be a stronghold in our growth and development strategy. The creation of a strong talent pipeline while retaining our high performing team members continues to be our mission. Talent management continues to be a top priority with our yearly performance review process focused on Portillo's seven leadership traits to be successful in the organization. Our growth, development, and retention strategies align on these leadership traits to build skills to be used both professionally and personally. We work with team members and managers to build individual development plans with training and experience, and we hold regularly scheduled development programs throughout the year for each level of leadership. We host webinars, workshops, and conferences each year on a variety of topics that are accessible to all team members. Further, we continue to hold bi-annual talent and succession planning summits to identify and support individuals with career pathing and development opportunities. We encourage team members to connect with one another in an informal mentoring program to build relationships and solidify their sense of belonging.

 Engagement & Experience. We aspire to provide an unrivaled experience for every team member during their journey with Portillo's. Creating lifelong memories for our team members and guests is paramount to the overall experience. We believe in our team members having a voice to share their ideas, feedback and contribute to organizational success. In 2024, we launched a digital engagement platform, Portillo's Connect, to engage team members at all levels across the Company. This forum allows our teams to recognize each other, celebrate their wins, and share information and ideas. We continue to partner with Gallup to implement our EverEngaged survey to gather, listen to and act on team member feedback. We conduct this survey annually to measure improvement and areas of focus. In 2024, we maintained our team member engagement in alignment with the restaurant industry at large. Our engagement results for multi-unit and general managers continue to be top quartile. Our team members reflected they know what is expected of them at work and they have the necessary materials to do their jobs well, which both strongly influence overall engagement. Our team members also reflected they understand how Portillo's values impact how they do their jobs. In addition to the survey, we regularly hold roundtable discussions with team members and conduct stay interviews with leaders to gain insights into ways we can cultivate an energizing, collaborative work environment. Additionally, we conduct an annual career aspiration survey for all RSC team members, crew chiefs, and field managers to understand their aspirations in development, career pathing, and what they need to succeed.

 We have also prioritized a flexible work environment, addressing life-work flexibility and balance across our different workplaces. Our scheduling system allows hourly team members to align their work schedule with their personal schedule, as well as submit schedules, request time-off and trade their shifts. For our RSC team members, we provide a hybrid work environment, with our teams coming in to the office for collaboration three days a week. In the spirit of continuing education, we also have a "no meeting" policy for Friday afternoons. Instead, our team members can use this time for professional development or focused work time. From Memorial Day through Labor Day, team members can also take this time for personal use and get an early start to the weekend.

 In 2024, we hosted our annual General Manager Summit, bringing together our restaurant leaders from across the country to align on company priorities, share best practices, and celebrate achievements. This event underscores our commitment to leadership development, operational excellence, and fostering a culture of collaboration. We also introduced our inaugural RSC Summit, designed to strengthen connections between corporate and restaurant teams. This event focused on enhancing cross-functional collaboration, improving support for our operations, and driving innovation to achieve our long-term strategic goals. The Summits are critical initiatives for strengthening leadership, fostering teamwork, and achieving business objectives.

 Total Rewards. The physical, financial, and mental well-being of our team members remains a top priority, and we continue to invest in their success. We believe in a total rewards philosophy of providing top quartile pay in our restaurants, especially across our leadership positions. We remain focused on compensating our team members fairly and equitably based on their roles and responsibilities.

 This commitment is evidenced by our investment in our compensation packages and robust suite of benefit offerings. In 2024, we completed a comprehensive benchmark analysis for our positions and made pay adjustments to preserve our competitive edge. We also enhanced our benefits package by transitioning our 401(k) plan to a new vendor that offers our team members a more streamlined experience and additional financial education resources and opportunities. During 2024, we enhanced existing benefits and offered new ones. We upgraded all medical, dental, and vision plans with the introduction of four coverage tiers, to offer greater flexibility. Our new benefits in 2024 include a commuter program for parking and transit expenses and expanded discount programs, including BenefitsHub for exclusive savings on cars, restaurants, and more. We also integrated OnePass which offers fitness and meal service discounts. Finally, we enhanced educational opportunities through partnerships and our Portillo's Greatness Scholarship Program, reinforcing our commitment to helping our team members achieve personal and professional goals.

 We believe all of our team members should act like owners of the Company, and we are committed to providing all team members with an ownership opportunity through our Employee Stock Purchase Plan ("ESPP"), internally referred to as "Beef Stock." Eligible employees can contribute up to 15% of their gross base earnings for purchases under the ESPP through regular payroll deductions, subject to an annual maximum dollar amount. In 2024, we issued 46,959 shares (net of shares withheld for taxes) under the ESPP. In addition to our Beef Stock program, all restaurant team members who are newly hired as, or promoted to, General Manager become eligible to participate in our long-term equity incentive plan. In 2024, many of our leaders received annual equity award grants, providing our team with opportunities to own Portillo's shares, which we believe supports retention of key team members and further drives engagement.

 Heart of Portillo's. We care deeply about our people and believe that by taking care of our team members, they will in turn take care of our guests. Our core values of Family, Greatness, Energy and Fun are the "Heart of Portillo's" and are ingrained in everything we do as a company. They guide how we support our Portillo's family, from our recruiting efforts, to the education of our team members, to making sure our Portillo's family is an accurate reflection of the communities in which we operate. It is our goal to make sure everyone across Portillo's knows they are an important part of our company. In 2024, the "Heart of Portillo's Fund," an IRC section 501(c)(3) charitable fund, raised over $200,000 to provide emergency assistance to team members. In 2024, the fund awarded over 60 grants and has provided support to team members for expenses following illness or injury, the unexpected death of a family member, negative impact from a natural disaster, and other financial hardships.

 Our Sourcing and Supply Chain

 Our supply chain approach is based on alignment with key strategic partners that are identified through a comprehensive evaluation process to ensure they meet our standards and expectations on a continual basis. We are committed to maintaining our high-quality food standards through fresh ingredients that meet our stringent specifications.

 Portillo's strongly believes in engaging with supplier partners who share a similar approach to our corporate values and practices. We align with key strategic partners that are identified through an evaluation process to ensure they can satisfy our standards and expectations. This approach affords our organization the opportunity for real-time performance assessments to identify any potential gaps and implement corrective measures where appropriate.

 We review and update our contingency plans on a regular basis to provide a reliable supply of products and services to our business. As part of our risk assessment strategy, the supply chain team identifies areas critical to supporting the restaurants and makes any necessary adjustments or institutes alternate programs.

 Suppliers and distribution partners are managed under both a supplier code of conduct and a pricing protocol that provides transparent insight to costing mechanisms. We expect all suppliers to meet rigorous standards set forth in the code, which cover areas such as human rights, business integrity, and environmental management. In addition, we engage directly with manufacturers to ensure compliance with negotiated contract pricing and requisite volume expectations.

 Distribution. Our main line distribution network is comprised of several independently-operated partners aligned under the UniPro umbrella, the largest food service distribution cooperative in the United States. This strategy affords us the opportunity to align with right-sized organizations that are dedicated to us which allows us to leverage volume and scale for a competitive advantage and exceptional customer service.

 Commissaries. We operate two commissaries to supply our network of restaurants with our signature beef, peppers and gravy for our Italian beef sandwiches and to ensure product consistency and quality. These ingredients are shipped to our restaurants where our team members will finish the preparation in our kitchens to serve our guests.

 Quality Systems. Quality and food safety are paramount to protecting our brand and are treated with the utmost priority. Our supplier and distribution partners participate in third-party audits to ensure all applicable quality system expectations are being met. Our restaurant locations are audited for food safety and quality compliance through a combination of third-party organizations and the Portillo's-managed quality and food safety team. Our commissaries also undergo food safety and quality audits on a regular basis and are regulated by the U.S. Department of Agriculture ("USDA") and Food and Drug Administration ("FDA").

 Our Competition

 The restaurant industry is highly competitive and fragmented. We compete primarily with quick service and fast casual concepts, and to a lesser extent, full-service restaurants. The number, size and strength of competitors vary by region. Our competition in these segments includes a variety of small, locally-owned restaurants, medium-sized regional restaurant concepts, and larger national restaurant concepts that provide some combination of dine-in, carry-out, drive-thru and delivery services to their guests. We believe competition with these restaurants is based primarily on quality and innovation in the food products offered, price and perceived value, quality of service experience (including technological and other innovations), speed of service, personnel, advertising and other marketing efforts, brand identification, restaurant location, and image and attractiveness of the restaurants.

 The restaurant industry is often affected by changes in consumer tastes; national, regional or local economic conditions; demographic trends; traffic patterns; the type, number and location of competing restaurants; and consumers' discretionary purchasing power. We compete within each market with national and regional chains and locally-owned restaurants for guests, management and hourly personnel and suitable real estate sites. In addition, expanding product offerings at fast casual and quick-service restaurants and the convenience of home delivery services, together with negative economic conditions, could cause consumers to choose less expensive alternatives or reduce the frequency of their restaurant visits. We expect intense competition to continue in all of these areas.

 Our Intellectual Property

 Our intellectual property includes our trademarks and service marks registered with the United States Patent and Trademark Office (including Portillo's and other names used by our restaurants), the trade dress of our restaurants, our websites and domain names (including our website at portillos.com and other websites and domain names used by our restaurants) and other unregistered intellectual property. We take steps to enforce and maintain our intellectual property, but infringement, validity challenges and other risks may adversely affect or even eliminate our intellectual property rights.

 Governmental Regulation and Environmental Matters

 We are subject to extensive federal, state and local government regulation, including those relating to, among others, public health and safety, nutritional content labeling, zoning and fire codes, environmental protection, and employment regulations. Failure to obtain or retain food or other licenses and registrations or exemptions would adversely affect the operations of restaurants.

 The development of additional restaurants will be subject to compliance with applicable regulations, including those relating to zoning, land use, water quality and retention, and the environment. We believe federal and state environmental regulations have not had a material effect on our operations, but more stringent and varied requirements of local government bodies with respect to zoning, land use and environmental factors, among others, could delay construction and increase development costs for new restaurants.

 We are also subject to the Fair Labor Standards Act, the Immigration Reform and Control Act of 1986 and various federal, state and local laws governing such matters as minimum wages, exempt versus non-exempt classification, overtime, unemployment tax rates, paid leave, workers' compensation rates, citizenship requirements and other working conditions. Our team members are typically paid more than the applicable minimum wage in the area where they work, and increases in federal or state minimum wages or unemployment benefits may result in increases in the wage rates paid. We are also subject to the Americans with Disabilities Act (the "ADA"), which prohibits discrimination on the basis of disability in public accommodations and employment, which may require us to design or modify our restaurants to make reasonable accommodations for individuals with disabilities.

 Additionally, any difficulties, delays or failures in obtaining licenses, permits, registrations, exemptions, or approvals could delay or prevent the opening of, or adversely impact the viability of, a restaurant in a particular area.

 Seasonality

 Our business is subject to seasonal fluctuations in that our revenues are typically nominally higher during the second, third and fourth quarters of the fiscal year. Our quarterly results have been and will continue to be affected by the timing of new restaurant openings and their associated pre-opening expenses. As a result of these factors, our financial results for any single quarter or for periods of less than a year are not necessarily indicative of the results that may be achieved for a full fiscal year.

 ITEM 1A. RISK FACTORS

 You should carefully consider each of the following risk factors in conjunction with other information provided in this Annual Report on Form 10-K and in our other public disclosures. Our business is subject to a number of risks, including risks that may prevent us from achieving our business objectives or may adversely affect our business, financial condition, results of operations, cash flows, liquidity or access to sources of financing, and/or the market value of our Class A common stock. These risks could cause our future results to differ materially from historical results and from guidance we may provide regarding our expectations of future financial performance. The risks described below highlight potential events, trends or other circumstances that could adversely affect our business.

 Risks Related to Our Business, Industry and Growth Strategies

 We are vulnerable to changes in economic conditions, increases in food and commodity costs and consumer preferences.

 Like other companies in the restaurant industry, we are dependent upon food and commodity availability and their costs impact our business and results. Food and commodity costs and availability can be volatile and are affected by factors outside of our control, including general economic conditions, inflation, labor shortages, seasonal fluctuations, weather and climate conditions, energy costs, global demand, trade protections and subsidies, food safety issues, infectious diseases, possible terrorist activity, cyberattacks, transportation issues, currency fluctuations, product recalls, and government regulations, among others.

 Food and commodity cost volatility has affected our profitability and reputation in the past and could do so in the future. While a portion of our commodities are subject to contract pricing, as our contracts expire we may unable to successfully (re)negotiate terms that protect us from inflation or the portion not covered by contract pricing might increase unexpectedly, creating unplanned price inflation. We experienced 4.2% and 5.5% commodity price inflation for the years ended December 29, 2024 and December 31, 2023, respectively.

 If the cost of our ingredients increase, we may suspend or permanently discontinue certain menu items rather than pay the increased cost for the ingredients. These changes to our menu could negatively impact our restaurant traffic and operational results during the shortage and thereafter. Additionally, we may be unable to offset all or even a portion of a future cost increase through menu price increases. Competitive conditions may

 Portillo's Inc. Form 10-K | 2

 limit our menu pricing flexibility and implementing menu price increases may change our guests' visit frequencies or purchasing patterns. Our industry depends on consumer discretionary spending and is affected by changes in consumer tastes, and macro- and micro-economic conditions (including economic downturns, consumer sentiment, inflation or increased food or energy costs). Factors such as traffic patterns, weather, fuel prices, local demographics, local regulations and the competitive landscape may adversely affect the performances of our individual locations.

 Our restaurants are primarily located in high-activity trade areas that often contain retail, lifestyle, and entertainment centers. We depend on high visitor rates in these trade areas to attract guests to our restaurants. A decline in traffic at these locations for a sustained period could have a material adverse effect on our business, financial condition and results of operations (collectively, "our Results").

 We may fail to open new restaurants or establish new markets or our new restaurants may not perform as well as anticipated, may not be profitable, or may close.

 Opening and profitably operating new restaurants in existing and new markets is key to our growth. Over the long term, we aim to increase our number of restaurants by approximately 12% to 15% annually. We may struggle to identify target markets, we may not be able to open our planned new restaurants within budget or on a timely basis, and our new restaurants may not perform as well as anticipated. New restaurant success is affected by several factors, many of which are beyond our control, including our ability to secure enough appropriate and attractive sites, and complete construction in a timely and cost-efficient manner.

 We may open restaurants in geographic markets where we have little or no prior operating experience. Moreover, consumer recognition of our brand has been important to the success of our existing restaurants, and our concept may have limited appeal in new markets. Restaurants in new markets may take longer to reach expected sales and profit and may have higher construction, occupancy and operating costs than existing restaurants. New restaurants in or near markets with existing restaurants could have a material adverse effect on sales at these existing restaurants. Failure on our part to recognize or respond to these challenges may adversely affect the success of new restaurants and could have a material adverse effect on our Results.

 Some of our restaurants have higher-than-normal sales volumes during the initial startup period, and our Restaurant-Level Adjusted EBITDA Margins are generally lower in the first 12 months of operation. In new markets, the period before average sales stabilize is less predictable because of our limited knowledge of these markets and consumers' limited awareness of our brand. In addition, our AUVs and same-restaurant sales may not increase at the rates our existing restaurants have achieved over the past several years. Our ability to operate new restaurants profitably and increase AUVs and same-restaurant sales will depend on many factors, some of which are beyond our control.

 We employ operating and financial targets, but new restaurants may not meet these targets or may take longer than anticipated to do so. If our new restaurants do not perform as planned, it could have a material adverse effect on our Results.

 Further, our existing restaurant management systems, financial and management controls and information systems (collectively, our "Infrastructure") may be inadequate to support our planned expansion. We may not enhance our Infrastructure quickly enough or effectively hire, train and retain team members, which could have a material adverse effect on our Results. If we experience a decline in financial performance, we may limit, delay or discontinue restaurant openings, or we may decide to close unprofitable restaurants.

 Our growth plans and ongoing capital expenditure ("capex") needs require us to spend capital, which may not be readily available.

 Our growth strategy depends on opening new restaurants using cash flows from operations. However, these cash flows may be insufficient to meet our needs. If cash is allocated ineffectively among our projects, or if any initiatives are unsuccessful, we may experience reduced profitability and we may need to delay, limit or eliminate planned restaurant openings, which could have a material adverse effect on our Results.

 As our restaurants mature, they require capital expenditures to remain competitive and maintain our brand standard. If we cannot fund capital expenditures using cash flows from operations, funds will need to be borrowed or otherwise obtained or capex investments will be delayed or eliminated, which could make those restaurants less attractive to guests and materially, adversely affect the business.

 Our same-restaurant sales may be lower than we expect in future periods.

 Same-restaurant sales continue to be critical to profitability because their profit margin is generally higher than the profit margin on new restaurant sales. Initiatives to grow same restaurant sales may be unsuccessful, we may miss our targets, or same-restaurant sales could decrease. Any such events could have a material adverse effect on our Results.

 Our marketing programs and any limited time or seasonal offerings may be unsuccessful and could fail to meet expectations, and our new menu items, advertising campaigns, heavy reliance on social media and restaurant designs and remodels may not generate increased sales or profits.

 We incur costs and expend other resources on marketing efforts for new and seasonal menu items, advertising campaigns, and restaurant designs and remodels to raise brand awareness and attract and retain guests. As our restaurant count increases and we expand into new markets, we expect to increase our marketing investment. If these initiatives are unsuccessful, we may incur expenses without the benefit of higher revenues,

 Portillo's Inc. Form 10-K | 3

 which could have a material adverse effect on our Results.

 Our marketing efforts rely heavily on the use of social media. Many of our competitors are expanding their use of social media, and new social media platforms are rapidly being developed, potentially making more traditional social media platforms obsolete. We must continuously evolve our social media strategies to maintain customer mindshare and brand relevance, particularly given the rise in digital focus among customers. We also invest in other marketing initiatives across digital channels and build customer awareness of, engagement with, and loyalty to our brand. These initiatives may not be successful, resulting in expenses incurred without higher sales or increased brand recognition.

 Laws and regulations governing the use of these platforms and devices continue to evolve. The failure by us or our agents to abide by applicable laws and regulations could subject us to investigations, lawsuits, liability, fines or other penalties and have a material adverse effect on our Results. An increase in the use of social media for product promotion and marketing may increase our costs, including those related to compliance, and increase the risk that such materials could contain problematic product or marketing claims or violate applicable regulations.

 Incidents involving food-borne illness and food safety could have an adverse effect.

 Food safety is a top priority and we dedicate substantial resources to help ensure that our guests enjoy safe, quality food products. However, food-borne illnesses and other food safety issues have occurred in the past and could occur in the future. Incidents or reports of food-borne or water-borne illness or other food safety issues, food contamination or tampering, team member hygiene and cleanliness failures, improper team member conduct, or guests spreading illness while at our restaurants could lead to product liability or other claims. Such incidents or reports could negatively affect our brand and reputation and could have a material adverse effect on our Results.

 We cannot guarantee that our food safety controls, procedures and training will be fully effective in preventing all food safety and public health issues at our restaurants. There is no guarantee that our restaurant locations will maintain the high levels of internal controls and training we require. Some food-borne illness incidents could be caused by third-party food suppliers or delivery services or during guest takeout or catered events. The risk may affect multiple restaurant locations. New illnesses resistant to our current precautions may develop in the future, or diseases with long incubation periods could arise, any of which could give rise to retroactive claims or allegations. One or more food safety instances in one of our restaurants could negatively affect sales at nearby or even all our restaurants, especially if highly publicized.

 Other restaurant chains have experienced incidents related to food-borne illness incidents that have had material adverse impacts on their operations, and it's possible we could suffer a similar impact if one or more of our restaurants were to experience a material food safety incident. Additionally, even if food-borne illnesses are not identified at our restaurants, our restaurant sales could be adversely affected if instances of food-borne illnesses at other restaurant chains were highly publicized.

 We face significant competition for guests, and our inability to compete effectively may affect our traffic, our sales and our operating profit margins, which could have a material adverse effect on our Results.

 The restaurant industry is intensely competitive. We compete directly and indirectly with national, regional and local limited-service (e.g., quick service or fast casual) and full-service restaurants on food quality, brand recognition, service, price and value, convenience, design and location. Some competitors have significantly greater financial, marketing, personnel and other resources, and many are well-established in our target markets. Many of our competitors have greater name recognition locally, regionally, or nationally in these target markets.

 Our continued success also depends on the popularity of our menu and guest experience. Consumer tastes, nutritional and dietary trends, traffic patterns and the type, number, and location of competing restaurants often affect restaurant performance, and our competitors may react more effectively to changes. In the past, some of our competitors have implemented promotional programs that provide price discounts or reward programs, and they may continue to do so in the future. If we cannot compete effectively, our traffic, restaurant sales and restaurant operating profit margins could decline, which could have a material adverse effect on our Results. If our competitors increase spending on marketing and other initiatives or our marketing expenditures decrease, or our advertising, promotions, and restaurant designs and locations are less effective than our competitors, it could have a material adverse effect on our Results.

 Our restaurant base is geographically concentrated in the Midwestern United States, and we could be negatively affected by conditions specific to that region.

 Our restaurants in the Midwestern United States represented approximately 71% of our restaurants as of December 29, 2024. Our restaurants in the Chicagoland area represented approximately 45% of our total restaurants and 54% of restaurants in our comparable base, as of December 29, 2024. Our comparable restaurant base is defined as the number of restaurants open for at least 24 full fiscal periods. Adverse changes in demographic, unemployment, economic, regulatory or weather conditions in the Midwestern United States have had, and may continue to have, material adverse effects on our Results. As a result of our concentration in this market, we have been, and in the future may be, disproportionately affected by conditions in this geographic area compared to other chain restaurants with a more distributed national footprint.

 Our competitors could open additional restaurants in the Midwestern United States, which could result in reduced market share for us in this key geographic region, which could have a material adverse effect on our Results.

 Portillo's Inc. Form 10-K | 4

 Damage to our reputation and negative publicity could have a material adverse effect on our Results.

 Our reputation and the perception of our brand are critical to our success. Any incident that erodes our consumer loyalty could significantly damage our business. We may be adversely affected by negative publicity relating to food quality, the safety, sanitation and welfare of our restaurant facilities, guest complaints or litigation, health inspection scores, integrity of our suppliers' food processing and other policies, practices and procedures, team member relationships and welfare, employment practices or other matters at one or more of our restaurants. Furthermore, similar negative publicity or occurrences with respect to other restaurants could also decrease our guest traffic and have a similar material adverse effect on our business. In addition, the volume of restaurant commentary has increased dramatically with the proliferation of social media platforms. Negative publicity may adversely affect us or some or all of our restaurants, regardless of whether allegations are valid, and we may not be able to respond effectively. For example, we, or other restaurant companies generally, have and could again come under criticism from animal rights and welfare activists for our business practices or those of our suppliers. We may also face scrutiny and criticism concerning sustainability matters, environmental stewardship, and other social issues. Such criticisms could impair our brand, our restaurant sales, our hiring, and our expansion plans. If we changed our practices because of concerns about animal welfare, or in response to such criticisms, our costs might increase, or we may have to change our suppliers or our menu. A similar risk exists with respect to food service businesses unrelated to us if customers mistakenly associate such unrelated businesses with our operations. Team member claims against us based on, among other things, alleged wage and hour violations, discrimination, harassment or wrongful termination may create not only legal and financial liability but negative publicity that could adversely affect us and divert our financial and management resources from more productive initiatives. A significant increase in the number of these claims or an increase in the number of successful claims could have a material adverse effect on our Results.

 The digital and delivery business, and expansion thereof, is uncertain and subject to risk.

 We believe digital investments to be a critical differentiator for our business, driving greater and more frequent engagement with new and existing customers. As the digital space continues to evolve, our technology must also evolve to stay competitive. If we do not maintain and innovate competitive digital systems, including our growing use of artificial intelligence in our operations, our digital business and sales may be adversely affected as we lose guests to competitors. We rely on third-parties for our ordering and payment platforms. Services performed by these third-parties have been, and could be in the future, damaged or interrupted by technological issues or cyberattacks, which could negatively impact our sales and harm our reputation.

 As availability of food delivery services increase, we understand the importance of meeting our guests' needs. We have invested in marketing to promote our delivery partnerships, which could negatively impact our profitability if that channel does not continue to expand. We rely on third-parties to fulfill delivery orders in a timely and professional fashion. If these third-party delivery companies cease doing business with us, do not continue their relationship with us on favorable terms, or cannot make their scheduled deliveries (including a shortage of drivers), it may have a negative impact on our sales or revenue. Errors in providing adequate delivery services may result in guest dissatisfaction, which could also result in guest attrition, loss in sales and damage to our brand image. Additionally, as with any third-party handling food, such delivery services increase the risk of food tampering while in transit. We developed sealed packaging to provide some deterrence against such potential food tampering, but some risk remains.

 Third-party food delivery services are competitive. If our delivery partners fail to effectively compete with other third-party delivery providers, our delivery business may suffer, resulting in a loss of sales. If any third-party delivery provider we partner with experiences damage to their brand image, we may also see ramifications due to our partnership with them.

 We have a limited number of suppliers and distributors for certain key ingredients. If our suppliers or distributors do not fulfill their contractual obligations, we could encounter supply shortages and incur higher costs.

 Due to the concentration of our suppliers and distributors ("our vendors"), the cancellation, disruption, delay or inability of these suppliers to deliver these products to our restaurants for any reason may materially and adversely affect our operations until we establish an alternative.

 We do not control our vendors' operations and our efforts to monitor their performance may be unsuccessful. If our vendors fail to comply with food safety or other laws and regulations, or face allegations of non-compliance, their operations may be disrupted and we may not be able to engage replacement suppliers on commercially reasonable terms or a timely basis, if at all.

 If our vendors do not fulfill their contractual obligations or we cannot identify alternative sources, we could encounter supply shortages and incur higher costs, which could have a material adverse effect on our results of operations. We have developed contingency plans to mitigate risks related to secondary supply, floor stocking arrangements, product diversification and inventory management, but there can be no assurance that we can obtain commercially reasonable terms or alternative product of equivalent quality.

 Any prolonged disruption in the operations of our two commissaries could harm our business.

 We currently operate two commissaries in Illinois, which produce the Italian beef, gravy and sweet peppers used in our restaurants. While we plan to continue investing in additional supply chain capacity in the future, as necessary, any prolonged disruption in the operations of any of our existing facilities, whether due to technical, operational or labor difficulties, product contamination, destruction or damage to the facility, limited capacity or other reasons, could adversely affect our Results.

 Portillo's Inc. Form 10-K | 5

 We depend on our executive officers and certain other key team members, the loss of whom could have a material adverse effect on our business.

 We rely upon the accumulated knowledge, skills and experience of our executive officers and certain other key team members. Our chief executive officer has been with us for more than five years and many of our executive officers have numerous years of experience in the food service industry. The loss of any of our executive officers could have a material adverse effect on our Results, as we may be unable to find suitable replacements on a timely basis, without incurring increased costs, or at all. There is a high level of competition for experienced, successful executive personnel in our industry. Our inability to meet our executive staffing requirements could have a material adverse effect on our Results.

 Failure to maintain our corporate culture as we grow could have a material adverse effect on our business.

 We believe that our corporate culture and values have been a critical component to our success. We have made substantial investments in our team. As we continue to grow, it may be difficult to maintain the innovation, teamwork, passion and focus on execution that are important to our culture. Any failure to preserve our culture could negatively impact our operations, including our ability to retain and recruit personnel and to effectively focus on and pursue our corporate objectives. If we cannot maintain our corporate culture as we grow, it could have a material adverse effect on our Results.

 Matters relating to employment and labor law could have a material adverse effect, result in litigation or union activities, add significant costs and divert management attention.

 Various federal and state labor laws govern our relationships with our team members and affect our operating costs, including the U.S. Occupational Safety and Health Act, which governs worker health and safety, the U.S. Fair Labor Standards Act, which governs such matters as minimum wages and overtime, and a variety of federal, state and local laws that govern employment law matters like employee classifications, unemployment tax rates, workers' compensation rates, family leave, paid leave, working conditions, safety standards, immigration status, payroll taxes, discrimination, and citizenship requirements. In addition, under the U.S. Patient Protection and Affordable Care Act ("ACA"), we must provide affordable coverage, as defined in ACA, to eligible team members, or make a payment per team member based on ACA's affordability criteria. Additionally, some state and local laws mandate certain levels of health benefits by some employers. Significant additional government regulations and new laws, including mandated increases in minimum wages, changes in exempt and non-exempt status, paid leave, or increased mandated benefits such as health care and insurance costs could have a material adverse effect on our business, financial condition and results of operations. In addition, changes in federal or state workplace regulations could adversely affect our ability to meet our financial targets.

 Federal law requires that we verify that our team members have the proper documentation and authorization to work in the U.S. Although we require all workers to provide us with government-specified documentation evidencing their employment eligibility, some of our team members may, without our knowledge, be unauthorized workers. We currently participate in the "E-Verify" program, an Internet-based, free program run by the U.S. government to verify employment eligibility in states where participation is required. However, use of the "E-Verify" program does not guarantee that we will properly identify all applicants who are ineligible for employment. Unauthorized workers are subject to deportation and we may be subject to fines or penalties if any of our workers are found to be unauthorized. Termination of a significant number of team members who lack work authorization may disrupt our operations, cause temporary increases in our labor costs as we train new team members and result in adverse publicity. We could also become subject to fines, penalties and other costs related to claims that we did not fully comply with all recordkeeping obligations of federal and state immigration compliance laws. As a result of such events, we could experience adverse publicity that may negatively impact our brand and may make it more difficult to hire and keep qualified team members. These factors could materially adversely affect our Results.

 Our business is subject to the risk of litigation by team members, consumers, suppliers, shareholders or others through private actions, class actions, administrative proceedings, regulatory actions or other litigation. The outcome of litigation, particularly class action and regulatory actions, is difficult to predict or quantify. In recent years, restaurant companies, including us, have been subject to lawsuits, including class actions, alleging violations of federal and state laws regarding workplace and employment conditions, discrimination, immigration status and similar matters. Some lawsuits have resulted in substantial damage awards. Similar lawsuits have been instituted from time to time alleging violations of various federal and state wage and hour laws regarding, among other things, employee meal deductions, overtime eligibility of managers and failure to pay for all hours worked. Whether or not claims against us are valid or whether we are found liable, claims may be expensive to defend and may divert time and money away from our operations and result in increases in our insurance premiums. In addition, they may generate negative publicity, which could reduce guest traffic and sales. Although we believe we maintain adequate levels of insurance, insurance may not be available at all or in sufficient amounts to cover all potential liabilities with respect to these or other matters. A judgment or other liability in excess of our insurance coverage or any adverse publicity resulting from claims could have a material adverse effect on our Results.

 Certain of our team members at our commissaries in Addison, IL and Aurora, IL voted on April 13, 2023 and April 30, 2024, respectively, in favor of being represented by a union. We filed objections to the Addison 2023 election with the National Labor Relations Board ("NLRB") on April 19, 2023, asserting that the promises made by the union and its agent prevented a free and fair election. We are actively pursuing litigation to set aside the election results. We filed an objection to the Aurora 2024 election with the NLRB on May 7, 2024, asserting that the promises made by the union and its agents prevented a free and fair election. Our objections were denied and we filed exceptions to this decision with the NLRB. Although we have not received other petitions to unionize, it is possible that additional team members may seek to be represented by labor unions in the future. If a significant number of our team members were to become unionized and collective bargaining agreement terms were significantly different from our

 Portillo's Inc. Form 10-K | 6

 current compensation arrangements, it could have a material adverse effect on our Results. In addition, a labor dispute involving some or all our team members may harm our reputation, disrupt our operations and reduce our revenues, and resolution of labor disputes could increase our costs. Further, if we enter into a new market with unionized construction companies, or the construction companies in our current markets become unionized, construction and build-out costs for new restaurants in such markets could materially increase.

 Labor quality, labor shortages or increased labor costs could have a material adverse effect on our Results.

 Our success depends upon our ability to attract, motivate and retain enough qualified team members to meet the needs of our new and existing restaurants. Competition for qualified team members in some areas could require higher wages and greater benefits. Our team members are typically paid more than the applicable minimum wage where they work. Increases in federal or state minimum wages, unemployment benefits, higher team member turnover rates, unionization of restaurant workers, or increases in the federally-mandated or state-mandated minimum wage, change in exempt and non-exempt status, or other employee benefits costs (including costs associated with health insurance coverage or workers' compensation insurance) may also increase wage rates. We invest significant time and money in the qualification and training of our personnel, so failure to retain team members will increase costs without improving Results. Inability to recruit or retain team members could also delay new restaurant openings, could adversely impact existing restaurants, or result in higher team member turnover in existing restaurants, increasing our labor costs and adversely affecting our Results.

 We may be unable to increase our menu prices in order to pass future increased labor costs on to our guests, in which case our operating margins would be negatively affected. If we increase menu prices to cover increased labor costs, the higher prices could adversely affect demand for our menu items, resulting in lower sales.

 We are exposed to risks associated with leasing property including long-term, non-cancelable leases and potential inability to renew expiring leases.

 Many of our restaurant leases are non-cancelable with initial terms of 10 to 20 years and typically provide for renewal options in five-year increments. Generally, our leases also require us to pay our share of the costs of real estate taxes, utilities, building operating expenses, insurance and other charges and may include rent escalations. If we close a restaurant, our lease obligations may remain, requiring, among other things, payment of the rent and other costs through the lease term. In addition, as leases expire for restaurants that we continue to operate, we may be unable to negotiate renewals on commercially acceptable terms or at all. As a result, we may close or relocate the restaurant, resulting in unanticipated construction costs, the delay or failure by the landlord to timely deliver the new restaurant location to us, and unfavorable commercial, residential or infrastructure development near our new restaurant location, among other costs and risks. Revenues and profit, if any, generated at a relocated restaurant may not equal those generated at the existing restaurant.

 Our business is subject to risks related to our sale of alcoholic beverages.

 We serve alcoholic beverages at most of our restaurants and we may expand service to additional restaurants in the future. Alcoholic beverage control regulations generally require our restaurants to apply to a state authority and, in certain locations, county or municipal authorities for an annual license that may be revoked or suspended for cause at any time. Alcoholic beverage control regulations impact many parts of restaurant operations, including minimum age of team members, advertising, trade practices, wholesale purchasing, inventory control and handling, storage and dispensing of alcoholic beverages and training. Failure to comply with these regulations and obtain or retain licenses could have a material adverse effect on our Results.

 We are also subject to "dram shop" statutes in certain states, which provide a person injured by an intoxicated person the right to recover damages from an establishment that wrongfully served alcoholic beverages to the intoxicated person. We carry liquor liability coverage as part of our existing comprehensive general liability insurance; however, litigation against restaurant chains has resulted in significant judgments and settlements under these statutes. These cases often seek punitive damages, which may not be covered by insurance, and such litigation could have a material effect on our Results. Regardless of whether any claims against us are valid or whether we are found liable, claims may be expensive to defend and may divert time and money away from operations, hurting our financial performance. A judgment significantly in excess of our insurance coverage or not covered by insurance could have a material adverse effect on our Results.

 An impairment in the carrying value of our goodwill, indefinite-lived intangible assets or long-lived assets could have a material adverse effect on our business.

 As of December 29, 2024, we had approximately $394.3 million of goodwill and $250.0 million of intangible assets, primarily related to the purchase price allocation performed in connection with the Berkshire Acquisition. We test goodwill and indefinite-lived intangible assets for impairment in the fourth quarter of each fiscal year and whenever events or changes in circumstances indicate that impairment may have occurred. If the book value of goodwill or other indefinite-lived intangible assets is impaired, such impairment would be charged to earnings in the period of impairment. We cannot accurately predict the amount and timing of any impairment. Should the value of goodwill or other indefinite-lived intangible assets become impaired in the future, such impairment could have a material adverse effect on our Results. See Note 6. Goodwill & Intangible Assets in the notes to the consolidated financial statements for additional information.

 Portillo's Inc. Form 10-K | 7

 Changes to estimates related to our property, fixtures and equipment and definite-lived intangible assets or operating results that are lower than our current estimates at certain restaurant locations may cause us to incur impairment charges or accelerate the amortization on certain long-lived assets, which could have a material adverse impact on our results of operations.

 Natural disasters, unusual weather conditions, pandemic outbreaks, political events, war and terrorism could disrupt our business and result in lower sales, increased operating costs and capital expenditures.

 Our Restaurant Support Center, restaurants, and their respective facilities, as well as certain of our vendors and customers, are located in areas that have been and could be subject to natural disasters such as floods, drought, hurricanes, tornadoes, fires or earthquakes. Because our restaurants are concentrated in the Midwestern United States and parts of the "Sunbelt," adverse weather conditions or changes in weather patterns, including those that may result in electrical and technological failures, may disrupt our business and may adversely affect our sales and operations. Such events could result in physical damage to one or more restaurants, the temporary closure of some or all of our restaurants or our vendors, a workforce shortage, supply chain disruption, or disruption of our technology support or information systems, all of which would increase our costs and disrupt our business. Pandemics, political or social unrest, and acts of war or terrorism in the past, and could in the future, have negative effects on our Results. The events described herein also could have indirect consequences like increased insurance costs if they result in significant loss of property or other insurable damage. Any of these factors, or any combination thereof, could have a material adverse effect on our Results.

 The increasing focus on environmental sustainability and social initiatives could increase our costs, harm our reputation, and adversely impact our Results.

 Investors, environmental activists, the media and governmental and nongovernmental organizations remain focused on a variety of environmental, social and other sustainability matters, including energy, water, and food and packaging waste management, food safety, nutritional content, labor practices, and supply chain and management food sourcing. We have experienced and may continue to experience pressure to make sustainability-related commitments. If we are not effective in addressing environmental, social and other sustainability matters affecting our industry, or setting and meeting relevant sustainability goals, our brand image may suffer. In addition, we may experience increased costs to achieve our sustainability goals, which could have a material adverse impact on our Results. We may also experience backlash from individuals, organizations and investors who do not support such initiatives, including those who support the enactment of "Anti-ESG" legislation or policies.

 Our inability or failure to execute on a comprehensive business continuity plan at our Restaurant Support Center following a disaster or force majeure event could have a material adverse impact on our Results.

 Many of our corporate systems and processes and corporate support for our restaurant operations are centralized at one location. We have disaster recovery procedures and business continuity plans in place to address crisis-level events, including hurricanes and other natural disasters, and back up and off-site locations for recovery of electronic and other forms of data and information, and events like the COVID-19 pandemic have provided a limited test of our ability to manage our business remotely. However, if we are unable to fully implement our disaster recovery plans, we may experience delays in recovery of data, an inability to perform vital corporate functions, tardiness in reporting and compliance requirements, a failure to adequately support field operations and other breakdowns in normal communication and operating procedures that could have a material adverse effect on our financial condition, results of operation and exposure for administrative and other legal claims. In addition, these threats are constantly evolving, which increases the difficulty of accurately and timely predicting, planning for and protecting against such threats. As a result, our disaster recovery procedures and business continuity plans may not adequately address all threats we face or protect us from resulting losses.

 Risks Related to Our Indebtedness

 Our level of indebtedness could have a material adverse effect on our business and limit our ability to plan for or respond to changes in our business.

 Our indebtedness could have significant effects on our business, such as (i) requiring us to dedicate a substantial portion of our cash flow to repay borrowings, reducing cash flow available to fund working capital, capital expenditures, acquisitions, our growth strategy and other general corporate purposes; (ii) limiting our ability to finance capital expenditures, acquisitions, debt service requirements, our growth strategy and other projects; (iii) limiting our ability to make investments, including acquisitions, loans and advances, and to sell, transfer or otherwise dispose of assets; (iv) making us more vulnerable to adverse changes in general economic, industry and competitive conditions, in government regulation and in our business by limiting our ability to plan for and react to changing conditions; (v) placing us at a disadvantage compared with our competitors that have less debt; and (vi) exposing us to risks inherent in interest rate fluctuations, including higher interest rate expense, because our borrowings are at variable interest rates.

 We may not generate sufficient cash flow to repay our indebtedness when due and meet our other cash needs. If this occurs, we may be required to pursue one or more alternative strategies, such as selling assets, refinancing or restructuring our indebtedness or selling additional debt or equity securities. We may not be able to refinance our debt or sell additional debt or equity securities or our assets on favorable terms, if at all, and if we must sell our assets, it may negatively affect our Results. If we are unable to pay our debts on time, credit ratings agencies may downgrade our credit rating, which may make it more difficult or expensive to refinance our existing debt or to obtain additional debt or equity financings in the future.

 Events beyond our control, including changes in general economic and business conditions, may affect our ability to satisfy certain financial

 Portillo's Inc. Form 10-K | 8

 covenants that apply under our credit agreements and we cannot guarantee that our lenders will waive any failure to satisfy such financial covenants.

 Risks Related to Our Organizational Structure

 The interests of Berkshire may conflict with our interests or the interests of the holders of our Class A common stock in the future.

 Berkshire Partners, our largest shareholder as of December 29, 2024, continues to own a significant percentage of our common stock. Berkshire engages in a range of investing activities, including investments in restaurants and other consumer-related companies. In the ordinary course of its business activities, Berkshire may engage in activities where its interests conflict with our interests or those of our shareholders. Our amended and restated certificate of incorporation provides that our directors and shareholders, including Berkshire, do not have any obligation to offer us an opportunity to participate in business opportunities presented to them even if the opportunity is one that we might reasonably have pursued (and therefore may be free to compete with us in the same business or similar businesses) and that, to the extent permitted by law, such directors and shareholders will not be liable to us or our shareholders for breach of any duty by reason of any such activities. Accordingly, the interests of Berkshire may supersede ours, causing them or their affiliates to compete against us or to pursue opportunities instead of us, for which we have no recourse. Such actions on the part of Berkshire and inaction on our part could have a material adverse effect on our Results. In addition, Berkshire may have an interest in pursuing acquisitions, divestitures and other transactions that, in its judgment, could enhance its investment in us, even though such transactions might involve risks to us, such as debt-financed acquisitions.

 Delaware law and our organizational documents, as well as our existing and future debt agreements, may impede or discourage a takeover, which could deprive our investors of the opportunity to receive a premium for their shares.

 Certain anti-takeover provisions of Delaware law and certain provisions of our current certificate of incorporation and bylaws may make it more difficult for a third-party to acquire control of us, even if a change of control would benefit shareholders. Among other things, these provisions: (i) do not permit cumulative voting for directors; (ii) delegate the sole power of a majority of the Board to fix the number of directors; (iii) provide the power of our Board to fill any vacancy on our Board, regardless of the cause of such vacancy; (iv) authorize the issuance of "blank check" preferred stock without shareholder approval; (v) eliminate the ability of shareholders to call special meetings; (vi) establish advance notice requirements for nominations for election to our Board or for proposing matters that can be acted on by shareholders at shareholder meetings; and (vii) limit use of shareholders' written consent.

 Our credit facilities impose, and we anticipate future facilities may impose, limitations on our ability to enter into change of control transactions, the occurrence of which could constitute an event of default. The foregoing factors, as well as the significant common stock ownership by Berkshire, could make acquisition of our Class A common stock less desirable, which, under certain circumstances, could reduce its market value.

 We are a holding company and our principal asset is our ownership of LLC Units in Portillo's OpCo. Accordingly, we are dependent upon distributions from Portillo's OpCo to pay dividends, if any, and taxes, make payments under the Tax Receivable Agreement and pay other expenses.

 We are a holding company whose principal asset is Portillo's OpCo LLC Units. We have no independent means of generating revenue. Portillo's OpCo is, and will continue to be, treated as a partnership for U.S. federal and applicable state and local income tax purposes and, as such, will generally not be subject to applicable federal, state, and local income taxes. Portillo's OpCo's taxable income will be allocated to holders of LLC Units, including us. Accordingly, we will incur income taxes on our allocable share of any taxable income of Portillo's OpCo. We will also incur expenses related to our operations, and will have payment obligations under the Tax Receivable Agreement. We intend to cause Portillo's OpCo to make distributions to the holders of LLC Units (including us) in amounts sufficient to cover the LLC Unit holders' obligations, however deterioration in the financial condition, earnings or cash flow of Portillo's OpCo and its subsidiaries may impair their ability to make such distributions. Additionally, if we need funds and Portillo's OpCo is restricted from making distributions to us under applicable law or regulation, its debt agreements or otherwise, we may be unable to obtain such funds on terms acceptable to us, or at all, which could have a material adverse effect on our liquidity and financial condition. See "Risks Related to Our Indebtedness" above.

 In certain circumstances, Portillo's OpCo will be required to make distributions to us and the other holders of LLC Units, and those distributions may be substantial.

 Under the Amended LLC Agreement, Portillo's OpCo will be required from time to time to make pro rata distributions in cash to us and the other holders of LLC Units at certain assumed income tax rates in amounts that are intended to be sufficient to cover the income taxes payable on our and the other LLC Unit holders' respective allocable shares of the taxable income of Portillo's OpCo. Given (i) potential differences in taxable income allocable to us and the other LLC Unit holders, (ii) the lower income tax rate applicable to corporations than individuals and (iii) the use of an assumed income tax rate, we may receive tax distributions significantly in excess of our income tax liabilities and obligations to make payments under the Tax Receivable Agreement. Our Board, in its sole discretion, will make any determination from time to time with respect to the use of any such excess cash so accumulated, but we will have no obligation to distribute such cash (or other available cash other than any declared dividend) to our shareholders. If we do not distribute such excess cash as dividends or otherwise undertake ameliorative actions, holders of our LLC Units (other than Portillo's Inc.) may benefit from any value attributable to such cash balances as a result of their ownership of Class A common stock following a redemption or exchange of their LLC Units, notwithstanding that such holders of our LLC Units (other than Portillo's Inc.) may previously

 Portillo's Inc. Form 10-K | 9

 have participated as holders of LLC Units in distributions by Portillo's OpCo that resulted in such excess cash balances at Portillo's Inc.

 Our organizational structure, including the Tax Receivable Agreement, confers certain benefits upon the TRA Parties that will not benefit holders of our Class A common stock to the same extent that it will benefit the TRA Parties, including substantial cash payments.

 Under the Tax Receivable Agreement, we are required to make cash payments to certain of our pre-IPO LLC Members (the "TRA Parties") equal to 85% of the income tax benefits, if any, that we actually realize, or in certain circumstances are deemed to realize, as a result of (i) our allocable share of existing tax basis in depreciable or amortizable assets related to LLC Units acquired in our IPO, (ii) certain favorable tax attributes we acquired from entities treated as corporations for U.S. tax purposes that held LLC Units prior to the Transactions ("Blocker Companies") (including net operating losses and the Blocker Companies' allocable share of existing tax basis), (iii) increases in our then allocable share of existing tax basis in depreciable or amortizable assets, and adjustments to the tax basis of the tangible and intangible assets of Portillo's OpCo and its subsidiaries, as a result of (x) sales or exchanges of interests in Portillo's OpCo (including repayment of the redeemable preferred units) in connection with our IPO and (y) future exchanges of LLC Units by pre-IPO LLC Members for Class A common stock and (iv) certain other tax benefits related to entering into the Tax Receivable Agreement, including payments made under the Tax Receivable Agreement.

 The Company's payment obligations under the Tax Receivable Agreement may be significant. Any payments made under the Tax Receivable Agreement will not be available for reinvestment in our business and will reduce our overall available cash flow. Tax Receivable Agreement payments are not conditioned on the TRA Parties' continued ownership of our shares. Furthermore, our obligations under the Tax Receivable Agreement could make us a less attractive target for an acquisition, particularly if an acquirer cannot use some or all of the tax benefits under the Tax Receivable Agreement. The amount of existing tax basis and anticipated tax basis adjustments and utilization of tax attributes, and the amount and timing of any payments under the Tax Receivable Agreement, will vary depending upon a number of factors, including the timing of redemptions or exchanges by the pre-IPO LLC Members, the price of shares of our Class A common stock at the time of the redemptions or exchanges, the extent to which such redemptions or exchanges are taxable, the amount of gain recognized by such holders of LLC Units, the amount and timing of the taxable income allocated to us or otherwise generated by us in the future, the portion of our payments under the Tax Receivable Agreement constituting imputed interest and the federal and state tax rates then applicable.

 In certain cases, payments under the Tax Receivable Agreement to the TRA Parties may be accelerated or significantly exceed any actual benefits we realize in respect of the tax attributes subject to the Tax Receivable Agreement and may impair our ability to consummate change of control transactions or negatively impact the value received by owners of our Class A common stock.

 The Tax Receivable Agreement provides that upon a "Change of Control" (which is defined to include, among other things, a 50% change in control of Portillo's Inc., the approval of a complete plan of liquidation or dissolution of Portillo's Inc., the disposition of all or substantially all of Portillo's Inc.'s direct or indirect assets or a change of a majority of the Board of Directors without approval of at least two-thirds majority of the then-existing Board members), upon a breach of any of our material obligations under the Tax Receivable Agreement or if, at any time, we elect an early termination of the Tax Receivable Agreement, then our payment obligations under the Tax Receivable Agreement will accelerate. Such accelerated payments will be calculated by reference to the present value (at a discount rate equal to the lesser of (i) 6.5% per annum and (ii) one year LIBOR (or its successor rate) plus 100 basis points) of all future payments that holders of LLC Units or other recipients would have been entitled to receive under the Tax Receivable Agreement, and such accelerated payments and any other future payments under the Tax Receivable Agreement will utilize certain valuation assumptions, including an assumption that we would have sufficient taxable income to fully utilize all potential future tax benefits that are subject to the Tax Receivable Agreement.

 In the case of certain changes of control, payments under the Tax Receivable Agreement will be accelerated and may significantly exceed the actual benefits we realize. We expect that the payments that we may make under the Tax Receivable Agreement in the event of a change of control will be substantial. As a result, our accelerated payment obligations and/or the assumptions adopted under the Tax Receivable Agreement in the case of a change of control may impair our ability to consummate change of control transactions or negatively impact the value received by owners of our Class A common stock in a change of control transaction, or require us to incur substantial costs to consummate such a transaction.

 We will not be reimbursed for any payments made to the TRA Parties under the Tax Receivable Agreement in the event that any tax benefits are disallowed.

 Payments under the Tax Receivable Agreement will be based on our tax reporting positions, and the U.S. Internal Revenue Service (the "IRS") or a state taxing authority may successfully challenge all or part of the tax benefits we claim in connection with such tax positions. If the outcome of any such challenge would reasonably be expected to materially affect a recipient's payments under the Tax Receivable Agreement, then we will not be permitted to settle or fail to contest such challenge without the TRA Party's consent (not to be unreasonably withheld or delayed). The TRA Parties' interests may differ from or conflict with our interests and they may exercise their consent rights in a manner adverse to our interests.

 Payments made under the Tax Receivable Agreement could significantly exceed any tax savings that we realize from the tax attributes that are the subject of the Tax Receivable Agreement. We will not be reimbursed for any cash payments previously made to the TRA Parties under the Tax Receivable Agreement if any tax benefits initially claimed by us and for which payment has been made to a TRA Party are ultimately disallowed. Excess cash payments made by us to a TRA Party will be netted against any future cash payments, if any, that we might otherwise be required to make to such TRA Party under the Tax Receivable Agreement once a challenge is finally settled or determined.

 Portillo's Inc. Form 10-K | 10

 Our business and operations could be negatively affected if we become the target of any securities litigation or shareholder activism efforts, which could cause us to incur significant expenses, hinder execution of our growth strategy and impact our stock price.

 After periods of volatility in the market price of a company's securities, securities class action litigation has at times been brought against the company experiencing such volatility. Publicly-traded companies may also become the target of shareholder activism campaigns, which could take many forms or arise in a variety of situations. Due in part to the potential volatility of our stock price, we may become the target of securities litigation or shareholder activism efforts. Securities litigation and shareholder activism, including proxy contests, could result in substantial costs and legal fees and divert management's and our Board of Directors' attention and resources from our day-to-day operations. Additionally, securities litigation and shareholder activism could give rise to perceived uncertainties as to our future, adversely affect our relationships with service providers and make it more difficult to attract and retain qualified personnel. Further, our stock price could be subject to significant fluctuation or otherwise be adversely affected by the events, risks and uncertainties of any securities litigation and shareholder activism matters.

 Risks Related to Intellectual Property, Information Technology, and Data Security

 The failure to protect and maintain our intellectual property, including our trademarks, could have a material adverse effect on our business.

 Our intellectual property includes our trademarks and service marks registered with the United States Patent and Trademark Office (including Portillo's), the trade dress of our restaurants, our websites and domain names (including our website at www.portillos.com) and other unregistered intellectual property (collectively, our "IP"). Our success depends on our continued ability to use our IP and licensed third-party intellectual property. We require continued use of our existing trademarks and service marks in order to increase brand awareness and develop our branded products. If our efforts to protect our IP are inadequate or if any third-party misappropriates, infringes, dilutes or otherwise violates our IP, the value of our IP may be harmed. For example, failure to register or enforce our trademarks, whether in print, on the Internet or through social media or other media, could prevent us from successfully challenging third parties who use trademarks similar to ours, which may cause consumer confusion, harm the public perception of our brand, prevent our brand and branded products from achieving and maintaining market acceptance and cause a material adverse effect on our Results. There can be no assurance that the steps we have taken to protect our IP in the United States will be adequate or will obtain or maintain any competitive advantage.

 It is possible that third parties will assert claims of infringement, misappropriation or other violations of intellectual property against us, or assert claims that a portion of our IP is invalid or unenforceable. Claims decided against us could invalidate or narrow our IP or allow competing uses, which could have a material adverse effect on our Results. Additionally, an infringement or misappropriation claim decided against us could result in us being required to pay damages, cease using our IP, develop or adopt non-infringing intellectual property or acquire a license to use the third-party intellectual property that is the subject of the asserted claim. Regardless of outcome, there could be significant expenses associated with the defense of such a claim. We may also from time to time have to assert claims against third parties and initiate litigation in order to defend our IP. Such litigation could result in substantial costs and diversion of resources, could be protracted with no certainty of success, or could fail to achieve an adequate remedy. Any of these occurrences could have a material adverse effect on our Results.

 Security breaches, system interruptions, material failure of our system, or complications with the implementation or usage of our new enterprise resource planning system could disrupt our operations, compromise confidential personally identifying information, subject us to loss, harm our business, and have a material adverse impact on our business, financial condition and results of operations.

 Our information technology systems, which in some cases rely on third-party providers, have in the past, and may in the future, experience service interruptions, degradation or other performance problems because of hardware and software defects or malfunctions, distributed denial-of-service and other cyberattacks, infrastructure changes, human error, natural/weather disasters, power losses, disruptions in telecommunications services, fraud, military or political conflicts, terrorist attacks, computer viruses, ransomware, malware, or other events. Our systems are also subject to break-ins, sabotage, theft, and intentional acts of vandalism perpetrated by criminal third parties, third parties we do business with, or team members. Our reliance on third parties increases our exposure to such risks as we cannot exercise direct control over such persons / entities.

 While we endeavor to keep all systems current, there can be no guarantee that we can update and maintain our systems at all times. In instances where we are unable to do so, our risk mitigation efforts may fail. Any such failure could lead to website downtime, disruptions to our information technology systems, or malicious behavior by threat actors. In 2024, we completed the implementation of our new ERP system, designed to accurately maintain the Company's financial records, enhance operational functionality, and provide timely information to the Company's management team related to the operation of the business. The ERP system implementation process has required, and will continue to require, the investment of personnel and financial resources as we support post-implementation efforts and system functionality. These post-implementation efforts could result in delays, increased costs, and other difficulties, and disruptions or difficulties in using our ERP system could result in harm to our business. Additionally, if the ERP system does not operate as intended, the effectiveness of our internal controls over financial reporting could be adversely affected or our ability to adequately assess those controls could be further delayed.

 We utilize technologies at our restaurants that support guest experience and transactions processes, including the processing of guest payments. We go to great lengths to vet the security capabilities of third parties that support these services. These services include retail technologies and related software applications. Although vendors similarly endeavor to maintain systems in a current and secure fashion, they are subject to the same implications as noted above, and these services can as a result be denigrated, compromised or otherwise impacted in a manner that disrupts our

 Portillo's Inc. Form 10-K | 11

 ability to operate. Although we will continue to take progressive steps to assess and promote the furthering security capabilities of third parties that support our restaurant operations, compromising events such as distributed denial of service, ransomware attack and other cyber attacks, natural / weather disasters or human error (and other events as noted above) may occur that will cause disruption to our vendors' system, that in turn may impact our ability to interact and transact with guests, on and off premise.

 Our business requires the collection, transmission, and retention of large volumes of guest and team member data, including personally identifiable information, through information technology systems maintained by us or vendors retained by us. In particular, our omni-channel approach relies in large part on our information technology systems to operate successfully and allow for capabilities like kiosk transactions, mobile order and pay, third-party delivery, and digital menu boards. Like many other companies, we have experienced, and will continue to experience, attempts to compromise our information technology systems, some of which have been successful but not material. As we expand our business channels, our risk exposure will increase proportionately. The techniques and sophistication used to conduct cyberattacks, as well as the sources and targets of these attacks, change frequently and may not be recognized until or after such attacks have occurred. We continue to make significant investment in physical and technological security measures, team member training, and third-party services to anticipate cyberattacks and prevent breaches, protect our information technology networks and infrastructure, and to identify vendors and service providers that could be vulnerable to damage, disruptions, shutdowns, data loss, or breaches due to criminal conduct, team member error, negligence or malfeasance, utility failures, natural disasters or other catastrophic events, we cannot guarantee that we will be successful in preventing every possible instance of cyberattacks, breach, or data loss, any of which could disrupt our operations, resulting in inefficiencies and a loss of profits.

 Additionally, the cybersecurity and privacy requirements, including the regulation of artificial intelligence, imposed by governmental regulations are evolving. Our systems may not be able to immediately satisfy applicable requirements, and may require significant additional investment and time to do so. A significant theft, loss or misappropriation of, or unauthorized access to, our guests' data or other proprietary data could result in fines, legal claims or proceedings, regulatory investigations and actions, or liability for failure to comply with privacy and information security laws, which could disrupt our operations, damage our reputation and expose us to claims from guests and team members, any of which could have a material adverse effect on our Results. Our cyber insurance and business interruption insurance may not be sufficient to cover all losses that may result from a cybersecurity incident. As a result, if we experience any outsized material impacts from a failure of our systems, our Results could be materially and adversely affected. Our reputation as a brand or as an employer could be adversely affected, which could impair our ability to attract and retain guests and qualified employees. There is also the question of interpretation of regulations that are implemented at a federal or state level, and our efforts to assess and validate the applicability of these measures, and if they apply in part or in full from a compliance standpoint. Although we strive to comply with regulations in the most timely manner possible, there may be instances in which an assessment that we deem to be valid and necessary is being conducted, in the face of a differing perspective from a governing agency. It is conceivable that we could be subjected to non-compliance penalties or similar circumstances, that would materially impact our Results.

 The rapid development and integration of artificial intelligence ("AI") and emerging technologies into our processes poses risks to our business.

 The use of AI technologies within our business processes must be implemented and managed effectively and ethically to avoid outputs that are false, biased, or inconsistent with our values and strategies. Failure to properly manage AI and emerging technologies, could also lead to unauthorized access to sensitive information, of which could harm our reputation and competitive position. At the same time, if we fail to keep pace with the rapid evolution of AI technologies, particularly in our industry, our competitive position and business results could suffer. In addition, the evolving regulatory landscape for AI technologies requires continuous monitoring and adaptation to ensure compliance and mitigate potential legal and operational risks.

 Failure to comply with existing and new federal and state laws and regulations relating to privacy, data protection, advertising and consumer protection, could have a material adverse effect.

 We rely on a variety of marketing and advertising channels and strategies, including email communications, affiliate partnerships, social media interactions, digital marketing, direct mailers, public relations initiatives and local community sponsorships, promotions and partnerships, and we are subject to various laws and regulations that govern such practices and activities.

 Laws and regulations relating to privacy, data protection, marketing and advertising, and consumer protection are evolving. These requirements may be interpreted inconsistently from one jurisdiction to another or may conflict with other rules or our practices. As a result, our practices may not have complied or may not comply in the future with all such laws, regulations, requirements and obligations. Any failure, real or perceived, by us to comply with our privacy policies, contractual commitments, or any federal or state privacy or consumer protection-related laws, regulations, industry self-regulatory principles, industry standards or codes of conduct, regulatory guidance, orders or other legal obligations relating to privacy or consumer protection could adversely affect our reputation, brand and business, and may result in claims, proceedings or actions against us or may require us to change our practices or stop using certain data sets. We may be contractually required to indemnify and hold harmless third parties from the costs or consequences of non-compliance with any laws, regulations or other legal obligations relating to privacy or consumer protection or any inadvertent or unauthorized use or disclosure of data that we store or handle in our operations.

 Federal and state governmental authorities continue to evaluate the privacy implications inherent in the use of third-party "cookies" and other methods of online tracking for behavioral advertising and other purposes. The U.S. government has limited and may further limit the ability of companies to engage in these activities. Additionally, some device manufacturers and web browsers have implemented, or announced plans to

 implement, means to make it easier for Internet users to prevent the placement of cookies or to block other tracking technologies, which, if widely adopted, could result in third-party cookies and other online tracking methods becoming significantly less effective. This could increase our operating costs, including new customer acquisition costs and, consequently, have a material adverse effect on our Results.

 Various federal and state legislative and regulatory bodies, or self-regulatory organizations, may expand current or enact new laws or regulations, or issue revised rules or guidance regarding privacy, data protection, consumer protection, and advertising. Additionally, the Federal Trade Commission and many state attorneys general are interpreting federal and state consumer protection laws to impose standards for the online collection, use, dissemination and security of data. Each of these laws and regulations, changes thereto, and any other new laws or regulations, could require changes to our business practices or restrict our use or storage of personal information, which may increase our compliance expenses and make our business more costly or less efficient. Such changes could harm our ability to develop an adequate marketing strategy and pursue our growth strategy effectively, which, in turn, could have a material adverse effect on our Results.

 Risks Related to Legal and Regulatory Matters

 We are subject to many federal, state and local laws with which compliance can be both costly and complex.

 The restaurant industry is subject to extensive federal, state and local laws and regulations, including without limitation those related to building and zoning requirements, and the preparation and sale of food. Such laws and regulations may change and failure to comply with applicable laws and regulations could adversely affect our results of operations. Many licenses, permits and approvals must be renewed annually and may be revoked, suspended or denied renewal if governmental authorities determine that our conduct violates applicable regulations. Difficulties or failure to obtain or maintain the required licenses, permits and approvals could adversely affect our existing restaurants and delay or result in our decision to cancel new restaurant openings, which could have a material adverse effect on our Results.

 The development and operation of our restaurants depend, to a significant extent, on the selection of suitable sites, which are subject to zoning, land use, environmental, traffic and other regulations and requirements. We are also subject to licensing and regulation by state and local authorities relating to health, sanitation, safety and fire standards.

 There is also a potential for increased regulation of certain food establishments in the United States, where compliance with a Hazard Analysis and Critical Control Points ("HACCP") approach would be required. The United States government continues to expand the sectors of the food industry that must adopt and implement HACCP programs. For example, the FDA Food Safety Modernization Act ("FSMA"), signed into law in January 2011, granted the U.S. Food and Drug Administration new authority regarding the safety of the entire food system, including through increased inspections and mandatory food recalls. We anticipate that the requirements may impact our industry. Additionally, our suppliers may initiate or otherwise be subject to food recalls that impact product availability, result in adverse publicity or require us to take costly actions or otherwise impact our business. We may be required to incur additional time and resources to comply with new food safety requirements made under the FSMA or other federal or state food safety regulations. Failure to comply with the laws and regulatory requirements of federal, state and local authorities could result in, among other things, revocation of required licenses, administrative enforcement actions, fines and civil and criminal liability. Other applicable laws could require us to make costly modifications to our restaurants or operations to comply with such laws.

 Compliance with current and future laws and regulations including those regarding permitted ingredients and disclosure of nutritional and allergen content may be costly and time-consuming. If we fail to comply with existing or future laws and regulations, we may be subject to governmental or judicial fines or sanctions or to litigation. The risks and costs associated with nutritional disclosures on our menus could also impact our operations, particularly given differences among applicable legal requirements and practices within the restaurant industry with respect to testing and disclosure, ordinary variations in food preparation among our own restaurants and the need to rely on the accuracy and completeness of nutritional information obtained from third-party suppliers. We may not be able to effectively respond to changes in consumer health perceptions, comply with further nutrient content disclosure requirements or adapt our menu offerings to trends in eating habits, which could have a material adverse effect on our Results. In addition, the restaurant industry has been subject to a growing number of claims based on the nutritional content of food products sold and disclosure and advertising practices. We may also be subject to this type of proceeding in the future and, even if we are not, publicity about these matters (particularly against the fast casual or traditional fast-food segments) may harm our reputation and could have a material adverse effect on our Results.

 We are subject to the Americans with Disabilities Act (the "ADA"), which, among other things, requires our restaurants to meet federally mandated requirements for individuals with disabilities. The ADA prohibits discrimination in employment and public accommodations on the basis of disability. Under the ADA, we could be required to modify our restaurants to provide service to, or make reasonable accommodations for the employment of, disabled persons. Our employment practices are also subject to the requirements of the U.S. Citizenship & Immigration Service ("USCIS") relating to citizenship and residency.

 The impact of current laws and regulations, the effect of future changes in laws or regulations that impose additional requirements and the consequences of litigation relating to current or future laws and regulations, or our inability to respond effectively to significant regulatory or public policy issues, could increase our compliance and other costs of doing business and could have a material adverse effect on our Results. Failure to comply with the laws and regulatory requirements of federal, state and local authorities could result in, among other things, revocation of required licenses, administrative enforcement actions, fines and civil and criminal liability. Compliance with all these laws and regulations can be costly and can increase our exposure to litigation or governmental investigations or proceedings.

 Portillo's Inc. Form 10-K | 13

 Tariffs and other trade policies could have a substantial impact on our business.

 The Company's business is dependent upon the availability of, among other things, agricultural commodities and other raw materials. U.S. relations with the rest of the world remain uncertain with respect to taxes, trade policies and tariffs, especially as the political landscape changes due to the recent U.S. presidential and congressional elections. Changes in U.S. administrative policy may lead to significant increases in tariffs for imported goods, which may impact prices for both domestic and imported goods, such as steel, lumber, and agricultural commodities. Imposition of tariffs may strain international trade relations and increase the risk that foreign governments implement retaliatory tariffs on goods imported from the United States. Similarly, interest rates may continue to rise and create further uncertainty and volatility in the market which would negatively impact our Results.

 These political and economic changes could have a material effect on global economic conditions and the stability of financial markets and could significantly reduce global trade. In addition to potential increases on tariffs, wars or conflicts could affect our ability to obtain raw materials, which could have a substantial impact on the costs associated with food, beverage and packaging of our menu items, as well as building construction materials and negatively impact our results.

 We can incur liabilities arising from environmental laws and compliance with environmental laws could increase our operating expenses.

 We are subject to federal, state and local laws, regulations and ordinances that govern activities or operations that may have adverse environmental effects, such as waste handling and disposal practices for solid and hazardous wastes, discharges to water and air and odor control and also impose liability for the costs of cleaning up, and damage resulting from, sites of past spills, disposals or other releases of hazardous materials. In particular, under applicable environmental laws, we may be responsible for remediation of environmental conditions and may be subject to associated liabilities, including liabilities for clean-up costs and personal injury or property damage, relating to our restaurants and the land on which our restaurants are located, regardless of whether such environmental conditions were created by us or another party. Third parties also may make claims for personal injuries and property damage associated with releases of, or actual or alleged exposure to, such hazardous or toxic substances at, on or from our restaurants. Some of our leases provide for indemnification of our landlords for environmental contamination, clean-up or owner liability.

 We could be party to litigation that could distract management, increase our expenses or subject us to material monetary damages or other remedies.

 Our guests occasionally file complaints or lawsuits alleging we caused an illness or injury they suffered at or after a visit to our restaurants, or that we have problems with food quality or operations. We are also subject to a variety of other claims that could arise in the ordinary course of our business, including personal injury claims, contract claims and claims alleging violations of federal and state securities laws or law regarding workplace and employment matters, equal opportunity, harassment, discrimination and similar matters, and we could encounter class action or other lawsuits related to these or different matters in the future. In recent years, a number of restaurant companies have been subject to such claims, and some of these lawsuits have resulted in the payment of substantial damages by the defendants. Regardless of whether any claims against us are valid, or whether we are ultimately held liable, claims may be expensive to defend and may divert time, attention, and money away from our operations. A judgment in excess of our insurance coverage for any claims could have a material adverse effect on our Results. Allegations may also result in adverse publicity and negatively impact our reputation.

 As a public company, we incur significant costs to comply with the laws and regulations affecting public companies which could harm our business and results of operations.

 As a public company, we are subject to the Exchange Act, the Sarbanes-Oxley Act ("SOX"), and the listing requirements of the Nasdaq, and other applicable securities rules and regulations. These rules and regulations have increased, and will continue to increase, our legal, accounting and financial compliance costs and have made and will continue to make some activities more time-consuming and costly. For example, these rules and regulations could make it more difficult and more costly for us to obtain director and officer liability insurance, and we may be required to accept reduced policy limits and coverage or to incur substantial costs to maintain the same or similar coverage. These rules and regulations could also make it more difficult for us to attract and retain qualified directors or executive officers. Our management and other personnel devote a substantial amount of time to these compliance initiatives. As a result, management's attention may be diverted from other business concerns, which could harm our business and results of operations. We may need to hire more team members in the future to comply with these requirements, which will increase our costs and expenses.

 If we fail to maintain effective internal controls over financial reporting, or if our internal controls are ineffective, our ability to produce timely and accurate financial information or to comply with Section 404 of the Sarbanes-Oxley Act of 2002 could be impaired.

 We are required to comply with Section 404 of the Sarbanes-Oxley Act ("Section 404"), which requires management to certify financial and other information in our quarterly and annual reports and provide an annual management report on the effectiveness of our internal controls over financial reporting. In addition, our independent registered public accounting firm must attest to the effectiveness of our internal controls over financial matters. To maintain compliance with Section 404, we will continue to employ internal resources and outside consultants to assess and document the adequacy of our internal controls over financial reporting, including validating that controls are functioning as documented and maintaining a continuous reporting and improvement process for internal controls over financial reporting. Despite our efforts, there is a risk that our internal controls over financial reporting may not comply with Section 404.

 Portillo's Inc. Form 10-K | 14

 Failure to achieve and maintain effective internal controls could have a material adverse effect on our Results. If we are not able to demonstrate Section 404 compliance, or if our internal controls over financial reporting are perceived as inadequate or it is perceived that we are unable to produce timely or accurate consolidated financial statements, investors may lose confidence in our business, the price of our Class A common stock could decline, we could become subject to investigations by the Nasdaq, the SEC or other regulatory agencies, or our Class A common stock may not be able to remain listed on the Nasdaq.

 Although we designed our disclosure controls and procedures to provide reasonable assurance that we are complying with the Exchange Act, any disclosure controls and procedures, no matter how well-conceived and executed, can provide only reasonable, not absolute, assurance. Judgments can be faulty and breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individuals, by collusion of two or more people or by an unauthorized override of the controls. Because of the inherent limitations in our control system, misstatements due to error or fraud may occur and not be detected and could materially adversely affect our Results.

 General Risks

 Fluctuations in our tax obligations, effective tax rate, and realization of our deferred tax assets may result in volatility of our results of operations.

 We are subject to income taxes in U.S. federal and various state tax jurisdictions. We record tax expense based on our estimates of current and future income tax payments, which may include reserves for uncertain tax positions in multiple tax jurisdictions, and valuation allowances related to the realizability of certain deferred tax assets. Significant judgment is required in determining our provision for income taxes, deferred tax assets ("DTAs") and our tax positions. At any one time, many tax years may be subject to audit by various taxing jurisdictions. The results of these audits and negotiations with taxing authorities may affect the ultimate settlement of these issues. Throughout the year there could be ongoing variability in our quarterly tax rates as events occur and exposures are evaluated.

 Our effective tax rate in a given financial reporting period may be materially impacted by a variety of factors including changes in the mix and level of earnings, varying jurisdictional tax rates, tax effects of equity-based compensation, changes in tax laws, regulations or interpretations thereof, cost related to intercompany restructuring, fluctuations in the valuation allowance or by changes to existing accounting rules or regulations. Further, new or revised tax legislation may be enacted in the future, which could negatively impact our current or future tax structure and effective tax rates.

 Our insurance may not provide adequate levels of coverage against claims.

 We believe that we maintain insurance customary and appropriate for businesses of our size and type. However, there are types of losses we may incur that cannot be insured against or that we believe are not economically reasonable to insure. Such losses could have a material adverse effect on our Results.

 Changes in accounting principles applicable to us could have a material adverse effect on our Results.

 Generally accepted accounting principles in the United States of America ("GAAP") are subject to interpretation by the Financial Accounting Standards Board ("FASB"), the American Institute of Certified Public Accountants, the SEC and various bodies formed to promulgate and interpret appropriate accounting principles. A change in these principles or interpretations could have a significant effect on our financial condition and results of operations, and could affect the reporting of transactions completed before the implementation of a change.

 Our amended and restated certificate of incorporation designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions that may be initiated by our shareholders, and designates the federal district courts of the United States as the sole and exclusive forum for claims arising under the Securities Act, which, in each case could limit our shareholders' ability to obtain a favorable judicial forum for certain disputes.

 Our current certificate of incorporation provides that, absent our written consent, the Court of Chancery of the State of Delaware (or if the Court of Chancery lacks jurisdiction, a state court located within the State of Delaware or the federal district court for the District of Delaware) shall, to the fullest extent permitted by law, be the exclusive forum for any (a) derivative action or proceeding brought on our behalf; (b) action asserting a claim of breach of a fiduciary duty owed by or other wrongdoing by any current or former director, officer, employee, agent or shareholder to us or our shareholders; (c) action asserting a claim arising under any provision of the Delaware General Corporate Law ("DGCL") or our amended and restated certificate of incorporation or amended and restated bylaws (as either may be amended from time to time), or as to which the DGCL confers jurisdiction on the Court of Chancery of the State of Delaware; or (d) action asserting a claim governed by the internal affairs doctrine.

 Our current certificate of incorporation provides that, absent our written consent, the federal district courts of the United States of America shall be the exclusive forum for the resolution of any action asserting a claim arising under the Securities Act or the rules and regulations promulgated thereunder.

 Any person or entity purchasing or otherwise acquiring or holding any interest in any shares of our capital stock shall be deemed to have notice of and consented to the forum provision in our certificate of incorporation, limiting such person's ability to bring a claim in a more favorable or

 Portillo's Inc. Form 10-K | 15

 convenient judicial forum, which may discourage such lawsuits, make them more difficult or expensive to pursue and result in less favorable shareholder outcomes. The enforceability of similar choice of forum provisions in other companies' certificates of incorporation has been challenged in legal proceedings, and it is possible that a court could find these types of provisions to be inapplicable or unenforceable. If a court were to find the choice of forum provisions in our certificate of incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could have a material adverse effect on our Results.

 Our annual and quarterly results of operations may fluctuate, and if our operating and financial performance in any given period does not meet the guidance that we have provided to the public or the expectations of our investors and securities analysts, the trading price of our Class A common stock may decline.

 Our annual and quarterly results of operations may fluctuate for a variety of reasons, many of which are beyond our control, including those described in these risk factors and variations in the timing and volume of our sales; the timing of expenditures in anticipation of future sales; changes in the cost or availability of our ingredients or labor; planned or actual changes to our capital or debt structure; strategic actions by us or our competitors, such as sales promotions, acquisitions or restructurings; significant litigation; legislation or other regulatory developments affecting us or our industry; changes in competitive and economic conditions generally; and general market conditions.

 Fluctuations in our performance may cause our results to fall below our public guidance or the investor and analyst expectations, which could cause the trading price of our Class A common stock to decline. Fluctuations in our results could also cause other problems, including but not limited to analysts or investors changing their valuation models for our shares, experiencing short-term liquidity issues, diminishing ability to retain or attract key personnel or other unanticipated issues.

 Quarterly results of operations may vary in the future and period-to-period comparisons may not be meaningful. Investors should not rely on the results of one quarter as an indication of future performance.

 ITEM 1C. CYBERSECURITY

 Risk Management Strategy

 Responsibility for cybersecurity risk management comes from a collective effort, with day-to-day oversight and management from our executive and information technology ("IT") teams. Additionally, the Audit Committee continues to take a more active role in setting both proactive and reactive strategies, with the overall Board overseeing our efforts and helping to guide our strategy.

 From a framework standpoint, we primarily utilize the National Institute of Standards and Technology ("NIST") framework to assess and mitigate cybersecurity risks. This framework guides our efforts to identify, analyze and contain any security threats, and advises as to potential actions to consider if a need arose to recover from a security incident.

 Our primary source of cybersecurity risk relates to security of our third-party service providers, whose activities and scale may present more desirable targets. However, we do maintain certain systems ourselves and appreciate the need to focus internally as well. We manage cybersecurity risk through a variety of tactics, including (i) the structure of our systems and platforms, (ii) the contractual terms with our third-party vendors, (iii) the proactive vulnerability assessments we conduct (or require our vendors to conduct), (iv) compliance with applicable regulations and continuous improvement around best practices, (v) mitigating user error and human vulnerabilities through training and guidance, (vi) attending security conferences and operationalizing new learnings and/or planning for environment changes in response to these learnings, and (vii) the placement of cybersecurity insurance policies. We also work with cross-functional partners and outside experts, including legal counsel and consultants to identify the legal requirements and industry practices and expectations that the Company's security measures should satisfy.

 We employ a "Defense in Depth" strategy to protect the Company, segmenting our systems and networks so that an attack on one segment does not allow for easier compromise of other systems and networks. Within the Company, administrative access to various systems is limited so that there is no universal access if an administrator-level account is compromised.

 We involve our IT team when negotiating contracts that could increase our cybersecurity risk exposure, so that the team is aware of the specific risks related to a given vendor and can provide feedback and advice on the contractual provisions necessary to prevent a cybersecurity incident, or in the event an incident does occur, to ensure that the Company has the necessary rights to act quickly to protect team members, guests, and our business and mitigate potential damage. We are continuously improving our processes and contract positions to reflect evolving risks and market

 Portillo's Inc. Form 10-K | 16

 practices.

 We appreciate the need to monitor and test our systems to make sure that they are working the way that they should. We negotiate with our vendors about a variety of monitoring, testing, and reporting provisions so that we can work with them to better address vulnerabilities. This may include sharing SOC 1 or 2 Type 2 audit reports, conducting periodic penetration and vulnerability testing, both internally and externally, and confirmation that vendors are adhering to applicable laws. Some of this testing and monitoring is conducted in-house and some is conducted by third-party vendors.

 We routinely conduct penetration testing across our various environments and networks, including our Restaurant Support Center, our restaurants and our cloud-based architecture and systems. We review penetration testing outcomes and take steps to address any meaningful findings, while documenting resolution steps these efforts.

 We work with team members at all levels to educate them about evolving risks, from well-known tactics and scams (e.g., phishing) to their more sophisticated descendants (e.g., spear phishing and smishing). Team members receive training on data security and privacy practices and are included in periodic awareness campaigns to test real-world responses. We continue to add further training opportunities as they become available and have incorporated "tabletop" exercises for our Board, our management team, and our team members into our risk mitigation efforts to help us refine our business interruption and response plans. The Company also employs and enforces policies to guide team member behavior and help protect against threats, which includes steps such as regular password updates, and obtaining permission to install third-party programs. Team member training reinforces the Company's risk management policies and procedures and the expectation that all team members will adhere to them.

 The Company also maintains a cybersecurity insurance policy that we believe is appropriate for a company of our size and risk profile, but it is possible that it may not fully cover the costs associated with a cybersecurity incident.

 We do not believe that risks from cybersecurity threats, including as a result of any previous cybersecurity incidents, have materially affected our business strategy, results of operations or financial condition. However, there is no guarantee that a future cybersecurity incident would not materially affect our future strategy, results or financial condition. For a more in-depth discussion of risks associated with cybersecurity and cybersecurity insurance risks, see Item 1A, "Risk Factors."

 Cybersecurity Governance

 Both the Board and the Audit Committee play an important role in the Board's oversight of cybersecurity threats. The Audit Committee receives periodic updates on the Company's risk profile and mitigation strategies and conducts forward-looking discussions about major IT changes that are planned, the risks involved and the Company's potential mitigation strategies. The Audit Committee shares updates with the broader Board. We presently have three Directors, Ann Bordelon, Chair of the Audit Committee, Paulette Dodson, and Noah Glass, who have cybersecurity risk management experience and we continue to monitor whether supplemental experience may be useful as cybersecurity threats continue to evolve.

 The IT Team manages day-to-day cybersecurity risks under the oversight of our Chief Information Officer ("CIO"), who is actively engaged in strategic planning, security assessments, and mitigation efforts. Our CIO has 10+ years of experience overseeing security practices at various multi-national restaurant concepts. Our CIO and Chief Financial Officer discuss IT matters on a routine basis, and as noted above, periodic reviews are conducted with the executive management team and the Audit Committee.

 We have an incident response process that is activated in the event of a direct or third-party attack. The plan is designed to help us detect, respond to and recover from cybersecurity incidents. Criteria are in place to determine the scope and severity of an incident, in relation to: incident reporting to the Audit Committee and/or the Board; disclosure or other external reporting; compliance with applicable legal obligations and mitigation of the impact to our brand, its reputation and any impacted parties.

 To address any gaps in the Company's collective expertise and to account for the ever-evolving nature of cybersecurity risks, the Company retains various consultants as noted above. The internal and external headcount, and the expertise of the employees and consultants, will change from time to time as we adapt to the changing cybersecurity environment.

 • Adjusted EBITDA** increased $2.5 million to $104.8 million.

 * For fiscal 2024, same-restaurant sales compares the 52 weeks from January 1, 2024 through December 29, 2024 to the 52 weeks from January 2, 2023 through December 31, 2023.
 ** Adjusted EBITDA and Restaurant-Level Adjusted EBITDA are non-GAAP measures. Definitions and reconciliations of Adjusted EBITDA to net income (loss) and Restaurant-Level Adjusted EBITDA to operating income, the most directly comparable financial measures presented in accordance with GAAP, are set forth under the section "Key Performance Indicators and Non-GAAP Financial Measures".

 Portillo's Inc. Form 10-K | 22

 In fiscal 2024, total revenue, operating income, net income, Restaurant-Level Adjusted EBITDA, and Adjusted EBITDA all improved versus the prior year. We believe this improvement stemmed from maintaining concentration on our four strategic pillars, which guide our short-term objectives and form the basis for long-term growth as discussed in Part I. Item 1. Business.

 In fiscal 2024, total revenue grew 4.5%, primarily due to new restaurant openings in 2024 and 2023. Same-restaurant sales declined 0.6% during fiscal 2024, compared to an increase of 5.7% during fiscal 2023. Fiscal 2023 includes the positive impact of the 53rd week.

 In fiscal 2024, we continued to see commodity inflation stabilize versus 2023 levels. Commodity inflation was 4.2% in fiscal 2024 compared to 5.5% in fiscal 2023. In fiscal 2024, we experienced a decrease of 0.1% in labor expenses, as a percentage of revenue, compared to fiscal 2023 primarily due to an increase in average check and lower variable-based compensation, partially offset by lower transactions and additional wage investments.

 In fiscal 2025, we are targeting 11% to 12% revenue growth and flat to 2% growth in same-restaurant sales. We expect our overall commodity inflation to stay consistent with recent trends and are currently estimating commodity inflation to be 3% to 5%. Additionally, we anticipate additional wage investments and are currently estimating 3% to 4% hourly wage inflation. We will continue to strategically offset these expense increases through menu price increases and operational efficiencies, while monitoring the competitive landscape as well as consumer sentiment to inform our pricing decisions. During January of 2025, we increased certain menu prices by approximately 1.5%. We will continue to prioritize strategies to drive higher traffic and mix at our restaurants while optimizing returns and retaining our top talent.

 Development Highlights

 During fiscal 2024, we opened 10 new restaurants in the Arizona, Florida, Illinois, Michigan, and Texas markets, for a total of 94 restaurants, including a restaurant owned by C&O. Two restaurants in the Texas market were our Restaurant of the Future ("ROTF") concept, a 6,250 square foot prototype restaurant. We also opened our seventh restaurant in the Dallas-Fort Worth market to meet our goal of achieving minimum scale (6-8 restaurants) within 24 months of our first opening. We also made significant strides in the Houston, Texas market with the opening of three new restaurants in the fourth quarter of 2024. Below are the 10 restaurants opened since the beginning of fiscal 2024:

 In fiscal 2025, we plan to open 12 new restaurants. Our near-term restaurant growth strategy is focused on leveraging our proven unit economic model primarily in markets outside Chicagoland with favorable macro-economic tailwinds where we already have a presence. Particularly, our current focus continues to be in the Sunbelt, primarily in Texas, with plans to enter the Atlanta, Georgia market. Simultaneously, we will continue to fill-in existing markets, including Chicagoland and adjacent markets as opportunities come available.

 Note: We use a 52- or 53-week fiscal year ending on the Sunday on or prior to December 31. Fiscal 2024 consisted of 52 weeks and fiscal 2023 consisted of 53 weeks. The 53rd week in fiscal 2023 included Christmas day, resulting in six additional operating days. Except as noted below, the Company's consolidated results of operations includes the 53rd week in fiscal 2023.

 Revenues, Net

 Revenues primarily represent the aggregate sales of food and beverages, net of discounts. Sales taxes collected from customers are excluded from revenues. Revenues in any period are directly influenced by, among other factors, the number of operating weeks in the period, the number of open restaurants, restaurant traffic, our menu prices, third-party delivery platform prices and product mix.

 Revenues for fiscal 2024 were $710.6 million compared to $679.9 million for fiscal 2023, an increase of $30.6 million or 4.5%. The increase in total revenue was primarily attributed to the opening of ten restaurants during fiscal 2024 and twelve restaurants in fiscal 2023, partially offset by a negative impact of $13.9 million due to the additional operating week in fiscal 2023 and a decrease in our same-restaurant sales. This increase in revenues was partially offset by a same-restaurant sales decrease of 0.6%, or $3.4 million. The same-restaurant sales decline was attributable to a 3.2% decrease in transactions, partially offset by an increase in average check of 2.6%. The higher average check was primarily driven by an approximate 4.6% increase in menu prices partially offset by product mix. To mitigate inflationary cost pressures, we implemented targeted menu price adjustments in 2024, including a 1.5% increase in January, another 1.5% increase at the end of March, and a 1.0% increase in June. Restaurants not in our Comparable Restaurant Base contributed $48.8 million of the total year-over-year increase. For the purpose of calculating same-restaurant sales as of December 29, 2024, sales for 71 restaurants were included in the Comparable

 Restaurant Base (as defined in "Key Performance Indicators and Non-GAAP Financial Measures" below) as of the end of fiscal 2024.

 *nm - not meaningful

 Food, Beverage and Packaging Costs

 Food, beverage and packaging costs include the direct costs associated with food, beverage and packaging of our menu items and third-party delivery commissions. The components of food, beverage and packaging costs are variable by nature, change with sales volume, are impacted by product and channel mix and are subject to increases or decreases in commodity costs, as well as geographic scale and proximity.

 Food, beverage and packaging costs for fiscal 2024 was $241.7 million compared to $230.9 million for fiscal 2023, an increase of $10.8 million or 4.7%. This increase was primarily driven by the opening of ten restaurants in fiscal 2024 and the opening of twelve restaurants in fiscal 2023 and a 4.2% increase in commodity prices, partially offset by lower third-party delivery commissions. As a percentage of revenues, net, food, beverage and packaging costs remained flat during fiscal 2024 as the increase in average check and lower third-party delivery commissions were offset by an increase in certain commodity prices.

 Labor Expenses

 Labor expenses include hourly and management wages, bonuses and equity-based compensation, payroll taxes, workers' compensation expense, and team member benefits. Factors that influence labor costs include wage inflation and payroll tax legislation, health care costs and the staffing needs of our restaurants.

 Labor expenses for fiscal 2024 were $181.1 million compared to $173.9 million for fiscal 2023, an increase of $7.2 million or 4.2%. This increase was primarily driven by the opening of ten restaurants in fiscal 2024 and the opening of twelve restaurants in fiscal 2023, and incremental investments to support our team members, including annual rate increases, partially offset by lower variable-based compensation. As a percentage of revenues, net, labor decreased 0.1% during fiscal 2024 primarily due to an increase in our average check and lower variable-based compensation, partially offset by the lower transactions and the aforementioned wage rate increases.

 Occupancy Expenses

 Occupancy expenses primarily consist of rent, property insurance and property taxes, and exclude occupancy expenses associated with unopened restaurants, which are recorded separately in pre-opening expenses.

 Portillo's Inc. Form 10-K | 25

 Occupancy expenses for fiscal 2024 were $36.6 million compared to $33.4 million for fiscal 2023, an increase of $3.3 million or 9.8%, primarily driven by the opening of ten restaurants in fiscal 2024 and the opening of twelve restaurants in 2023. As a percentage of revenues, occupancy expenses increased 0.2% during fiscal 2024.

 Other Operating Expenses

 Other operating expenses consist of direct marketing expenses, utilities and other expenses incidental to operating our restaurants, such as credit card fees and repairs and maintenance.

 Other operating expenses for fiscal 2024 were $83.0 million compared to $76.6 million for fiscal 2023, an increase of $6.4 million or 8.3%, primarily due to the opening of ten restaurants in fiscal 2024 and the opening of twelve restaurants in 2023 and an increase in repair and maintenance expenses, IT expenses, and utilities, partially offset by a decrease in operating supplies and advertising expenses. As a percentage of revenues, net, operating expenses increased 0.4%.

 General and Administrative Expenses

 General and administrative expenses primarily consist of costs associated with our corporate and administrative functions that support restaurant development and operations, including marketing and advertising costs incurred as well as legal and professional fees. General and administrative expenses also include equity-based compensation expense. General and administrative expenses are impacted by changes in our team member count and costs related to strategic and growth initiatives.

 General and administrative expenses for fiscal 2024 were $75.1 million compared to $78.8 million for fiscal 2023, a decrease of $3.7 million or 4.8%. This decrease was primarily driven by lower equity and variable-based compensation and insurance expenses, partially offset by an increase in advertising expenses driven by the Chicagoland ad campaign, and professional fees and software license fees related to our ERP and human capital management ("HCM") system implementations.

 Pre-Opening Expenses

 Pre-opening expenses consist primarily of wages, occupancy expenses, which represent rent expense recognized during the period between the date of possession of the restaurant facility and the restaurant opening date, travel for the opening team and other supporting team members, food, beverage, and the initial stocking of operating supplies. All such costs incurred prior to the opening are expensed in the period in which the expense was incurred. Pre-opening expenses can fluctuate significantly from period to period, based on the number and timing of openings and the specific pre-opening expenses incurred for each restaurant. Additionally, restaurant openings in new geographic market areas will experience higher pre-opening expenses than our established geographic market areas, such as the Chicagoland area, where we have greater economies of scale and incur lower travel and lodging costs for our training team.

 Pre-opening expenses for fiscal 2024 were $9.2 million compared to $9.0 million for fiscal 2023, an increase of $0.2 million or 2.4%. This increase was due to the number, timing and location of executed and planned new restaurant openings for fiscal 2024 as compared to fiscal 2023.

 Depreciation and Amortization

 Depreciation and amortization expenses consist of the depreciation of fixed assets, including leasehold improvements, fixtures and equipment and the amortization of definite-lived intangible assets, which are comprised of recipes.

 Depreciation and amortization expense for fiscal 2024 was $27.3 million compared to $24.3 million for fiscal 2023, an increase of $3.0 million or 12.3%. This increase was primarily attributable to incremental depreciation of capital expenditures related to the opening of ten restaurants in fiscal 2024 and the opening of twelve restaurants in fiscal 2023.

 Net Income Attributable to Equity Method Investment

 Net income attributable to equity method investment consists of a 50% interest in C&O, which runs a single restaurant located within the Chicagoland market. We account for the investment and financial results in the consolidated financial statements under the equity method of accounting as we have significant influence but do not have control.

 Portillo's Inc. Form 10-K | 26

 Net income attributable to equity method investment for fiscal 2024 was $1.2 million compared to $1.4 million for fiscal 2023, a decrease of $0.2 million or 12.3%. This decrease was primarily driven by an increase in restaurant-level operating expenses, partially offset by an increase in sales.

 Other Income, Net

 Other income, net includes, among other items, income resulting from discounts received for timely filing of sales tax returns, management fee income associated with our investment in C&O, trading gains or losses on our deferred compensation plan and gains, losses on asset disposals, and asset impairment charges.

 Other income, net for fiscal 2024 was $0.3 million compared to $1.0 million for fiscal 2023, a decrease of $0.7 million or 69.9%. Other income, net decreased primarily due to a technology asset impairment charge.

 Interest Expense

 Interest expense primarily consists of interest and fees on our credit facilities and the amortization expense for debt discount and deferred issuance costs.

 Interest expense for fiscal 2024 was $25.6 million compared to $27.5 million for fiscal 2023, a decrease of $1.9 million or 6.7%. This decrease was primarily driven by a lower effective interest rate due to improved lending terms associated with our 2023 Term Loan and 2023 Revolver Facility.

 Our effective interest rate was 7.53% and 8.36% as of December 29, 2024 and December 31, 2023, respectively.

 Interest Income

 Interest income primarily consists of interest earned on our cash, cash equivalents and restricted cash.

 Interest income for fiscal 2024 was $0.3 million compared to $0.2 million for fiscal 2023, an increase of $0.1 million or 45.8%. This increase was primarily driven by converting our bank accounts to interest bearing during fiscal 2023.

 Tax Receivable Agreement Liability Adjustment

 We are party to a Tax Receivable Agreement liability with certain members of Portillo's OpCo that provides for the payment by us of 85% of the amount of tax benefits, if any, that Portillo's Inc. actually realizes or in some cases is deemed to realize as a result of certain transactions.

 The Tax Receivable Agreement liability adjustment was $9.1 million for the fiscal year ended December 29, 2024 related to a remeasurement primarily due to activity under equity-based compensation plans and effective state tax rate changes. The Tax Receivable Agreement liability adjustment was $3.3 million for the fiscal year ended December 31, 2023.

 Loss on Debt Extinguishment

 There was no loss on debt extinguishment for fiscal 2024. Loss on debt extinguishment for fiscal 2023 was $3.5 million due to the write-off of debt discount and deferred issuance costs associated with the payoff of the 2014 Credit Agreement as described in Note 9. Debt.

 Income Tax Expense

 Portillo's OpCo is treated as a partnership for U.S. federal, state and local income tax purposes and is generally not subject to income taxes. Rather, any taxable income or loss generated by Portillo's OpCo is allocated to its members in relation to their respective ownership percentage of Portillo's OpCo. As of the IPO, we are subject to U.S. federal, state and local income taxes with respect to our allocable share of any taxable income or loss of Portillo's OpCo, as well as any stand-alone income or loss generated by Portillo's Inc.

 Income tax expense for fiscal 2024 was $6.8 million compared to $3.2 million for fiscal 2023, an increase of $3.6 million or 109.3%. Our effective income tax rate for fiscal 2024 was 16.2%, compared to 11.5% for fiscal 2023. The increase in our effective income tax rate for fiscal 2024 compared to fiscal 2023 was primarily driven by an increase in the Company's ownership interest in Portillo's OpCo, which increases its

 Portillo's Inc. Form 10-K | 27

 share of taxable income of Portillo's OpCo, remeasurement of deferred tax assets due to effective state tax rate changes and recording of net operating losses in the prior year. This was partially offset by the decrease in the valuation allowance and the exercise and vesting of equity-based awards.

 Net Income Attributable to Non-controlling Interests

 We are the sole managing member of Portillo's OpCo. We manage and operate the business and control the strategic decisions and day-to-day operations of Portillo's OpCo and we also have a substantial financial interest in Portillo's OpCo. Accordingly, we consolidate the financial results of Portillo's OpCo, and a portion of our net income is allocated to non-controlling interests to reflect the entitlement of the pre-IPO LLC Members who retained their equity ownership in Portillo's OpCo (the "pre-IPO LLC Members"). The weighted average ownership percentages for the applicable reporting periods are used to attribute net income to Portillo's Inc. and the non-controlling interest holders.

 Net income attributable to non-controlling interests for fiscal 2024 was $5.6 million, compared to $6.4 million for fiscal 2023. The decrease in net income attributable to non-controlling interests for fiscal 2024 was primarily due to a decrease in the non-controlling interest holders' weighted average ownership from 25.9% for fiscal 2023 to 17.0% for fiscal 2024, partially offset by an increase in net income for fiscal 2024 compared to fiscal 2023. The weighted average ownership percentage decreased due to the Secondary Offering and Redemption of LLC units as discussed in Note 1. Description Of Business of our consolidated financial statements.

 Key Performance Indicators and Non-GAAP Financial Measures Overview

 In addition to the GAAP measures presented in our financial statements, we use the following key performance indicators and non-GAAP financial measures to evaluate our business, measure our performance, develop financial forecasts and make strategic decisions. These key measures include same-restaurant sales, average unit volume ("AUV"), Adjusted EBITDA, Adjusted EBITDA Margin, Restaurant-Level Adjusted EBITDA and Restaurant-Level Adjusted EBITDA Margin. The Company includes these measures because management believes that they are important to day-to-day operations and overall strategy and are useful to investors in that they provide for greater transparency with respect to supplemental information used by management in its financial and operational decision-making.

For fiscal 2023, same-restaurant sales compares the 53 weeks from December 26, 2022 through December 31, 2023 to the 53 weeks from December 27, 2021 through January 1, 2023.

 Key Performance Indicators

 Change in Same-Restaurant Sales

 The change in same-restaurant sales is the percentage change in year-over-year revenue (excluding gift card breakage) for the comparable restaurant base, which is defined as the number of restaurants open for at least 24 full fiscal periods (the "Comparable Restaurant Base"). As of December 29, 2024 and December 31, 2023, there were 71 and 68 restaurants in our Comparable Restaurant Base, respectively. The Comparable Restaurant Base excludes C&O, as described in Note 2. Summary Of Significant Accounting Policies of our consolidated financial

 Portillo's Inc. Form 10-K | 28

 statements.

 A change in same-restaurant sales is the result of a change in restaurant transactions, average guest check, or a combination of the two. We gather daily sales data and regularly analyze the guest transaction counts and the mix of menu items sold to strategically evaluate menu pricing and demand. Measuring our same-restaurant sales growth allows management to evaluate the performance of our existing restaurant base. We believe this measure provides a consistent comparison of restaurant sales results and trends across periods within our core, established restaurant base, unaffected by results of restaurant openings and enables investors to better understand and evaluate the Company's historical and prospective operating performance.

 Average Unit Volume

 AUV is the total revenue (excluding gift card breakage) recognized in the Comparable Restaurant Base, including C&O, divided by the number of restaurants in the Comparable Restaurant Base, including C&O, by period.

 This key performance indicator allows management to assess changes in consumer spending patterns at our restaurants and the overall performance of our restaurant base.

 Non-GAAP Financial Measures

 To supplement the consolidated financial statements, which are prepared and presented in accordance with GAAP, we use the following non-GAAP financial measures: Adjusted EBITDA and Adjusted EBITDA Margin, and Restaurant-Level Adjusted EBITDA and Restaurant-Level Adjusted EBITDA Margin. Accordingly, these measures are not required by, nor presented in accordance with GAAP, but rather are supplemental measures of operating performance of our restaurants. You should be aware that these measures are not indicative of overall results for the Company and that Restaurant-Level Adjusted EBITDA and Restaurant-Level Adjusted EBITDA Margin do not accrue directly to the benefit of shareholders because of corporate-level expenses excluded from such measures. These measures and our calculations may not be comparable to similar measures reported by other companies. These measures are important measures to evaluate the performance and profitability of our restaurants, individually and in the aggregate, but also have important limitations as analytical tools and should not be considered in isolation as substitutes for analysis of our results as reported under GAAP.

 Adjusted EBITDA and Adjusted EBITDA Margin

 Adjusted EBITDA represents net income (loss) before depreciation and amortization, interest expense, interest income, and income taxes, adjusted for the impact of certain non-cash and other items that we do not consider in our evaluation of ongoing core operating performance as identified in the reconciliation of net income (loss), the most directly comparable GAAP measure to Adjusted EBITDA. Adjusted EBITDA Margin represents Adjusted EBITDA as a percentage of revenues, net.

 We use Adjusted EBITDA and Adjusted EBITDA Margin (i) to evaluate our operating results and the effectiveness of our business strategies, (ii) internally as benchmarks to compare our performance to that of our competitors and (iii) as factors in evaluating management's performance when determining incentive compensation.

 We believe that Adjusted EBITDA and Adjusted EBITDA Margin are important measures of operating performance because they eliminate the impact of expenses that do not relate to our core operating performance.

 Restaurant-Level Adjusted EBITDA and Restaurant-Level Adjusted EBITDA Margin

 Restaurant-Level Adjusted EBITDA is defined as revenue, less restaurant operating expenses, which include food, beverage and packaging costs, labor expenses, occupancy expenses and other operating expenses. Restaurant-Level Adjusted EBITDA excludes corporate level expenses and depreciation and amortization on restaurant property and equipment. Restaurant-Level Adjusted EBITDA Margin represents Restaurant-Level Adjusted EBITDA as a percentage of revenues, net.

 We believe that Restaurant-Level Adjusted EBITDA and Restaurant-Level Adjusted EBITDA Margin are important measures to evaluate the performance and profitability of our restaurants, individually and in the aggregate.

 Liquidity and Capital Resources

 Our primary sources of liquidity are cash from operations, cash and cash equivalents on hand, and availability under our 2023 Revolver Facility. As of December 29, 2024, we maintained cash and cash equivalents and restricted cash balance of $22.9 million and had $69.7 million of availability under our 2023 Revolver Facility, after giving effect to $5.3 million in outstanding letters of credit.

 Our primary requirements for liquidity are to fund our working capital needs, operating lease obligations, capital expenditures, and general Restaurant Support Center needs. Our requirements for working capital are not significant because our guests pay for their food and beverage purchases in cash or on debit or credit cards at the time of the sale and we are able to sell many of our inventory items before payment is due to the supplier of such items. Our ongoing capital expenditures are principally related to opening of new restaurants, existing capital investments (both for remodels and maintenance), as well as investments in our Restaurant Support Center infrastructure. Additionally, we continue to invest in technology, including the deployment of self-service kiosks and upgrades to our IT infrastructure, to improve operational efficiency and the guest experience.

 Based upon current levels of operations and anticipated growth, we expect that cash flows from operations will be sufficient to meet our needs for at least the next twelve months and the foreseeable future.

 In connection with the IPO, we entered into a Tax Receivable Agreement ("TRA") with certain of our pre-IPO LLC Members, pursuant to which we will generally be required to pay 85% of the amount of cash savings, if any, in U.S. federal, state, and local income tax that we actually realize or are deemed to realize, as a result of (i) our allocable share of existing tax basis in depreciable or amortizable assets relating to LLC Units acquired in the IPO, (ii) certain favorable tax attributes acquired by the Company from the Blocker Companies (including net operating losses and the Blocker Companies' allocable share of existing tax basis), (iii) increases in our allocable share of then existing tax basis in depreciable or amortizable assets, and adjustments to the tax basis of the tangible and intangible assets, of Portillo's OpCo and its subsidiaries, as a result of (x) sales or exchanges of interests in Portillo's OpCo (including the repayment of the redeemable preferred units) in connection with the IPO and (y) future redemptions or exchanges of LLC Units by pre-IPO LLC Members for Class A common stock and (iv) certain other tax benefits related to entering into the TRA, including payments made under the TRA. See Note 19. Subsequent Events for information about a recent amendment to the TRA.

 As of December 29, 2024, we estimate that our obligation for future payments under the TRA totaled $324.6 million. Amounts payable under the TRA are contingent upon, among other things, (i) generation of future taxable income over the term of the TRA and (ii) future changes in tax laws. If we do not generate sufficient taxable income in the aggregate over the term of the TRA to utilize the tax benefits, then we would not be required to make the related TRA payments. The payments that we are required to make will generally reduce the amount of overall cash flow that might have otherwise been available to us, but we expect the cash tax savings we will realize to fund the required payments. Assuming no

 Portillo's Inc. Form 10-K | 31

 material changes in relevant tax law and that we earn sufficient taxable income to realize all tax benefits that are subject to the TRA, we estimate that the tax savings associated with all tax attributes described above would aggregate to approximately $381.9 million as of December 29, 2024. Under this scenario, we would be required to pay the TRA Parties approximately 85% of such amount, or $324.6 million, primarily over the next 15 years, declining in year 16 through year 47. During the year ended December 29, 2024, we made a TRA payment of $4.4 million relating to tax year 2022. We expect a payment of $7.7 million relating to tax year 2023 to be made within the next 12 months.

 Note: We use a 52- or 53-week fiscal year ending on the Sunday on or prior to December 31. Fiscal 2024 consisted of 52 weeks and fiscal 2023 consisted of 53 weeks. The 53rd week in fiscal 2023 included Christmas day, resulting in six additional operating days.

 Operating Activities

 Net cash provided by operating activities for fiscal 2024 was $98.0 million compared to net cash provided by operating activities of $70.8 million for fiscal 2023, an increase of $27.3 million or 38.5%. This increase was primarily driven by the change in operating assets and liabilities of $23.6 million and higher net income of $10.3 million, partially offset by the change in non-cash items of $6.6 million.

 The $23.6 million change in our operating asset and liability balances was primarily driven by operating assets and liabilities being a source of net cash of $25.7 million in fiscal 2024, compared to a source of net cash of $2.1 million in the fiscal 2023 driven by the change in accounts payable, deferred lease incentives, other current assets, and inventories. The increase in net income for the fiscal 2024 was primarily due to higher revenue partially offset by the factors driving the aforementioned expenses as described in the consolidated results of operations for fiscal 2024 compared to fiscal 2023. The $6.6 million change from fiscal 2023 in non-cash charges was primarily driven by lower equity-based compensation expense and the loss on debt extinguishment in the prior year, partially offset by higher depreciation and amortization and an increase in income tax expense in the current year.

 Investing Activities

 Net cash used in investing activities was $88.1 million for fiscal 2024 compared to net cash used in investing activities of $87.8 million for fiscal 2023, an increase of $0.3 million or 0.3%. This increase was primarily due to the number of restaurant openings and builds in process during 2024 and the planned restaurant openings for 2025, partially offset by adopting a more cost effective restaurant format.

 Financing Activities

 Net cash provided by financing activities was $2.5 million for fiscal 2024 compared to net cash used in financing activities of $16.9 million for fiscal 2023, an increase of $19.4 million or 114.8%. This increase is primarily due to the payment and borrowing of long-term debt in connection with our refinancing in fiscal 2023 as described in Note 9. Debt and higher proceeds from stock option exercises. The increase was partially offset by an increase in payments made under the TRA of $3.6 million.

 2023 Revolver Facility and Liens

 On February 2, 2023, Holdings, the Borrower, the other Guarantors party thereto from time to time, each lender party thereto from time to time and Fifth Third Bank, National Association, as Administrative Agent, L/C Issuer and Swing Line Lender entered into the 2023 Credit Agreement which provides for the 2023 Term Loan in an initial aggregate principal amount of $300.0 million and the 2023 Revolver Facility in an initial aggregate principal amount of $100.0 million. Refer to Note 9. Debt for additional information and Note 19. Subsequent Events for information

 Portillo's Inc. Form 10-K | 32

 about further amendments to the 2023 Term Loan and 2023 Revolver Facility.

 Material Cash Requirements

 Our material cash requirements greater than twelve months include:

 Debt. Refer to Note 9. Debt to the consolidated financial statements for further information of our obligations and the timing of expected payments. Also, see Note 19. Subsequent Events for information about further amendments to the 2023 Term Loan and 2023 Revolver Facility.

 Lease obligations. Refer to Note 10. Leases to the consolidated financial statements for further information of our obligations and the timing of expected payments.

 Liabilities under the tax receivable agreement. Refer to Note 14. Income Taxes to the consolidated financial statements for further information of our obligations.

 We may enter into purchase commitments relating to supply chain, construction, marketing and other service-related arrangements that occur in the normal course of business. Such commitments are typically short-term in nature and are not material as of December 29, 2024.

 Critical Accounting Estimates

 This discussion and analysis of financial condition and results of operations is based upon the Company's consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of these financial statements requires the Company to make estimates, judgments, and assumptions that can have a meaningful effect on the reporting of consolidated financial statements. We describe our significant accounting policies in Note 2. Summary Of Significant Accounting Policies to the consolidated financial statements.

 Critical accounting estimates are defined as those reflective of significant judgments, estimates and uncertainties, which may result in materially different results under different assumptions and conditions. Due to their inherent uncertainty, these judgments and estimates may be subject to change, which could materially impact future periods.

 Liabilities Under Tax Receivable Agreement

 We are a party to the TRA under which we are contractually committed to pay certain of our pre-IPO LLC Members 85% of the amount of any tax savings that we actually realize, or in some cases are deemed to realize, as a result of certain transactions. Amounts payable under the TRA are contingent upon, among other things, (i) generation of future taxable income over the term of the TRA and (ii) future changes in tax laws. If we do not generate sufficient taxable income in the aggregate over the term of the TRA to utilize the tax benefits, then we would not be required to make the related TRA payments. Therefore, we would only recognize a liability for TRA payments if we determine it is probable that we will generate sufficient future taxable income over the term of the TRA to utilize the related tax benefits. As of December 29, 2024, we recognized $324.6 million of liabilities relating to our obligations under the TRA, after concluding that it was probable that we would have sufficient future taxable income to utilize the related tax benefits. If we determine in the future that we will not be able to fully utilize all or part of the related tax benefits, we would de-recognize the portion of the liability related to the benefits not expected to be utilized.

 Additionally, we estimate the amount of TRA payments expected to be paid within the next 12 months and classify this amount as current on our consolidated balance sheet. This determination is based on our estimate of taxable income for the previous fiscal year and the timing of the anticipated payments. To the extent our estimate differs from actual results, we may be required to reclassify portions of our liabilities under the TRA between current and non-current. We expect a payment of $7.7 million to be made within the next 12 months. See Note 19. Subsequent Events for information about a recent amendment to the TRA.

 Portillo's Inc. Form 10-K | 33

 Income Taxes

 We are subject to U.S. federal, state and local income taxes with respect to our allocable share of any taxable income of Portillo's OpCo and will be taxed at the prevailing corporate tax rates. In addition to tax liabilities, we also will incur expenses related to our operations, plus payments under the TRA, which are expected to be significant. We intend to cause Portillo's OpCo to make cash distributions to us in an amount sufficient to allow us to pay our tax obligations and operating expenses, including distributions to fund any ordinary course payments due under the TRA. We anticipate that we will account for the income tax effects and corresponding TRA's effects resulting from future taxable exchanges or redemptions of LLC Units of pre-IPO LLC Members by us or Portillo's OpCo by recognizing an increase in our deferred tax assets, based on enacted tax rates at the date of the purchase or redemption.

 The amounts recorded for both the deferred tax assets and the liability for our obligations under the TRA were estimated at the time of the IPO and secondary offerings as a reduction to stockholders' equity, and the effects of changes in any of our estimates after this date will be included in net income (loss). Similarly, the effect of subsequent changes in the enacted tax rates will be included in net income (loss).

 In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that the deferred tax assets will be realized. The ultimate realization of the deferred tax assets is dependent upon the generation of future taxable income during the periods in which temporary differences become deductible. We will record a valuation allowance when necessary to reduce the carrying value of certain deferred tax assets to their respective net realizable value (if any). As of December 29, 2024, we had $197.4 million of deferred tax assets, net of the recorded valuation allowance.

 Under the provisions of ASC 740—Income Taxes, as it relates to accounting for uncertainties in tax positions, we recognize the tax benefit of tax positions to the extent that the benefit will more likely than not be realized. The determination as to whether the tax benefit will more likely than not be realized is based upon the technical merits of the tax position as well as consideration of the available facts and circumstances. For the tax year ended December 29, 2024, we did not record any unrecognized tax benefits.

 ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

 Commodity and Food Price Risks

 We are exposed to commodity price risks. Many of the ingredients we use to prepare our food, as well as our packaging materials, are commodities or are affected by the price of other commodities. Factors that affect the price of commodities are generally outside of our control and include raw material inputs, geopolitical events, weather conditions, currency markets and global supply and demand dynamics, among other items.

 In an effort to minimize the impact of fluctuations in price and availability, we monitor the primary commodities we purchase and may enter into purchasing contracts and pricing arrangements when considered to be advantageous. Structured programs within our organization exist to mitigate adverse impacts and proactively direct risk management strategies across our portfolio of key products, services and energy platforms.

 Interest Rate Risk

 Our credit facilities incur interest at a floating rate. We seek to manage exposure to adverse interest rate changes through our normal operating and financing activities. As of December 29, 2024 and December 31, 2023, we had a total of $313.8 million and $309.4 million, respectively, in outstanding borrowings under our 2023 Term Loan and 2023 Revolver Facility, excluding unamortized debt discount and deferred issuance costs. See Note 9. Debt for individual balances for our 2023 Term Loan and 2023 Revolver Facility as of December 29, 2024. Based on the terms of the 2023 Credit Agreement, as of December 29, 2024, a change of one hundred basis points in the applicable interest rate would cause an increase or decrease in interest expense of approximately $3.1 million on an annual basis.

 Effects of Inflation

 Inflation has the potential to impact restaurant operating expenses at all levels. Whether that pressure originates from commodity costs, labor expenses, energy or transportation, this can have a material influence on restaurant margins.

 Several strategies are employed to combat the ongoing inflationary pressures, including improvement to restaurant operating efficiencies, strategic menu price increases and supplier partner engagement via pricing programs or continuous improvement initiatives. A well-balanced portfolio of varying risk management approaches related to supplier partner management assists in ensuring varying degrees of cost mitigation. These platforms vary from long-term, fixed price agreements to commodity market-based indexed pricing programs.

 In addition, a portion of the leases for our restaurants provide for contingent rent obligations based on a percentage of sales. As a result, an increase in occupancy and related expenses will offset a proportionate share of any menu price increases at our restaurants.

 Labor Costs

 Increases in minimum wage, health care and other benefit costs may have a material adverse effect on our labor costs. We operate in many states and localities where the minimum wage is significantly higher than the federal minimum wage.

 The market for labor in the United States is competitive and has resulted in pressure on wages and may continue to do so in the future. Increases in minimum wage and market pressure may also result in increases in the wage rates paid for non-minimum wage positions. Many states and localities are also passing laws regulating employment practices and working conditions which could have a material adverse effect on our labor costs in those areas.

 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

 To the stockholders and the Board of Directors of Portillo's Inc.

 Opinion on the Financial Statements

 We have audited the accompanying consolidated balance sheets of Portillo's Inc. and subsidiaries (the "Company") as of December 29, 2024 and December 31, 2023, the related consolidated statements of operations, stockholders' and members' equity, and cash flows, for each of the three years in the period ended December 29, 2024, and the related notes and the schedule listed in the Index at Item 15 (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 29, 2024 and December 31, 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 29, 2024, in conformity with accounting principles generally accepted in the United States of America.

 We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 29, 2024, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 25, 2025, expressed an unqualified opinion on the Company's internal control over financial reporting.

 Basis for Opinion

 These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

 We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

 Critical Audit Matter

 The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

 Income Taxes – Tax Receivable Agreement—Refer to Note 2 and 14 to the financial statements

 Critical Audit Matter Description

 On October 20, 2021, the Company completed its initial public offering in a series of transaction steps, which resulted in the Company owning a majority of PHD Group Holdings, LLC. The Company is a C-corporation holding company owning a partnership interest in PHD Group Holdings, LLC, commonly referred to as an Up-C structure. In connection with the initial public offering, the Company entered into a Tax Receivable Agreement ("TRA") and recorded a liability under the TRA. Under the TRA, the Company will be required to pay certain pre-IPO owners 85% of the amount of cash savings, if any, in U.S. federal, state, or local tax that the Company actually realizes. The payments related to the initial and subsequent exchanges are treated as additional consideration paid, which in turn increases the tax basis of the Company's investment in the Partnership. Most of this tax basis is amortizable under requisite sections of the Internal Revenue Code. The amounts payable, as well as the timing of such payments, under the TRA are dependent upon significant future events and assumptions, including among others: (i) the amount

 Portillo's Inc. Form 10-K | 37

 and timing of exchanges, (ii) the characterization of the tax basis step-up, (iii) the depreciation and amortization periods that apply to the increase in tax basis, (iv) the amount and timing of taxable income the Company generates in the future and (v) the U.S. federal, state, and local income tax rates then applicable.

 Given the complexity of the calculation and high volume of inputs used to estimate the TRA liability, performing audit procedures to evaluate the accuracy of the calculation and appropriateness of the inputs required a high degree of auditor judgment and an increased extent of effort, including the need to involve our income tax specialists.

 How the Critical Audit Matter Was Addressed in the Audit

 Our audit procedures related to the TRA liability included the following, among others:

 • We tested the effectiveness of controls over management's determination of the TRA liability, including controls over significant tax judgments and estimates.

 • With the assistance of our income tax specialists, our audit procedures related to the TRA liability included evaluating and assessing the following, among others:
 We evaluated the appropriateness of management's application of the accounting for the TRA liability, and the reasonableness of the methods, inputs, and assumptions used by management to determine the TRA liability.
 We evaluated the impact of partnership exchange transactions on the computation of the TRA liability by performing testing, on a sample basis, of exchanges, tax basis amounts and calculations related to the stepup in basis.
 For each tax basis step-up captured by the TRA, we evaluated the characterization of the step-up for appropriateness and consistency with the TRA.
 We tested the appropriateness of the tax rates and tax amortization utilized in the determination of the TRA liability, by agreeing to the terms in the TRA and applicable federal and state tax laws.
 We evaluated the Company's taxable income forecast as it relates to the estimated timing and amount of utilization of the tax basis step-up captured by the TRA.
 We tested the mathematical accuracy of the TRA liability calculation by recomputing the liability.

 NOTE 1. DESCRIPTION OF BUSINESS

 Portillo's Inc. ("Inc.") was formed and incorporated as a Delaware corporation on June 8, 2021. Inc. was formed for the purpose of completing an initial public offering ("IPO") and related reorganization transactions in order to carry on the business of PHD Group Holdings LLC and its subsidiaries ("Portillo's OpCo"). Portillo's Inc. is the sole managing member of Portillo's OpCo, and as sole managing member, Inc. operates and controls all of the business and affairs 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"). Unless the context otherwise requires, references to "we," "us," "our," "Portillo's," and the "Company" refer to Portillo's Inc. and its subsidiaries, including Portillo's OpCo.

 The Company operates restaurants in 10 states that serve Chicago-style hot dogs and sausages, Italian beef sandwiches, char-grilled burgers, fresh chopped salads, crinkle-cut fries, homemade chocolate cake and more, along with two food production commissaries in Illinois. As of December 29, 2024 and December 31, 2023, the Company had 93 and 83 restaurants in operation, respectively. The Company also had two non-traditional locations in operation as of December 29, 2024 and December 31, 2023. These non-traditional locations include a food truck and a ghost kitchen (small kitchen with no store-front presence, used to fill online orders). Portillo's Inc., additionally has a 50 % interest in a single restaurant owned by C&O Chicago, L.L.C. ("C&O"), which is excluded from the Company's restaurant count noted above. The Company's principal corporate offices are located in Oak Brook, Illinois.
 Secondary Offerings and Redemption of LLC Units

 In the fourth quarter of 2024, certain pre-IPO LLC Members redeemed 840,992 LLC Units in the aggregate, together with an equal number of shares of Class B common stock, for newly-issued shares of Class A common stock on a one -for-one basis, in accordance with the terms of the Second Amended and Restated LLC Agreement of Portillo's OpCo, dated as of October 20, 2021.

 In the first quarter of 2024, the Company completed a secondary offering of 8,000,000 shares of the Company's Class A common stock at an offering price of $ 14.37 per share ("Q1 2024 Secondary Offering"). The Company granted BofA Securities, Inc., the underwriter (the "Underwriter"), a 30-day option to purchase up to an additional 1,200,000 shares of Class A common stock. The underwriter did not exercise its overallotment option within the 30-day period. We used all of the net proceeds from the Q1 2024 Secondary Offering to purchase LLC Units and corresponding shares of Class B common stock from certain pre-IPO LLC Members and to repurchase shares of Class A common stock from the shareholders of the entities treated as corporations for U.S. tax purposes that held LLC Units prior to the Transactions ("Blocker Companies") at a price per LLC Unit or share of Class A common stock, as applicable, equal to the public offering price per share of Class A common stock, less the underwriting discounts and commissions. The proceeds from the Q1 2024 Secondary Offering were used to (i) purchase 2,167,629 existing shares of Class A common stock from the shareholders of the Blocker Companies and (ii) redeem 5,832,371 LLC Units held by the pre-IPO LLC Members. In connection with the redemption, 5,832,371 shares of Class B common stock were surrendered by the pre-IPO LLC Members and canceled and the Company received 5,832,371 newly-issued LLC Units, increasing the Company's total ownership interest in Portillo's OpCo. As a result, Portillo's did not receive any proceeds from the offering, and the total number of shares of Class A common stock and Class B common stock did not change; however, the number of outstanding shares of Class A common stock increased by the same number of the canceled shares of Class B common stock.

 In the first quarter of 2023, the Company completed one secondary offering of 8,000,000 shares at an offering price of $ 21.05 per share. On April 5, 2023, the Underwriter exercised its overallotment option in part, to purchase an additional 620,493 shares of the Company's Class A common stock at an offering price of $ 21.05 per share.

 In the third and fourth quarters of 2022, the Company completed two secondary offerings of 8,066,458 shares (including 66,458 shares sold to the underwriters pursuant to their overallotment option) and 8,000,000 shares, respectively, of the Company's Class A common stock at an offering price of $ 23.75 and $ 22.69, respectively, per share.

 The holders of LLC Units (other than the Company) may from time to time require Portillo's OpCo to redeem all or a portion of their LLC Units (together with an equal number of shares of Class B common stock) for newly-issued shares of Class A common stock on a one -for-one basis.

 As of December 29, 2024, the Company owned 85.6 % of Portillo's OpCo and the pre-IPO LLC Members owned the remaining 14.4 % of Portillo's OpCo.

 NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

 Basis of Presentation

 The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") and include the accounts of the Company and its subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

 The Company does not have any components of other comprehensive income (loss) recorded within its consolidated financial statements, and therefore, does not separately present a statement of comprehensive income (loss).

 Fiscal Year

 The Company operates on a 52- or 53-week fiscal year ending on the Sunday on or prior to December 31. In a 52-week fiscal year, each quarterly period is comprised of 13 weeks. The additional week in a 53-week fiscal year is added to the fourth quarter. Fiscal 2024 and 2022 each consisted of 52 weeks. Fiscal 2023 consisted of 53 weeks. The 53rd week in fiscal 2023 coincided with Christmas, resulting in six additional operating days. The fiscal periods presented in this report are fiscal years ended December 29, 2024 ("fiscal 2024"), December 31, 2023 ("fiscal 2023") and December 25, 2022 ("fiscal 2022"), respectively. Unless otherwise stated, references to years in this report relate to fiscal years.

 Use of Estimates

 The preparation of these consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of sales and expenses during the period. Actual results could differ from those estimates.

 Cash and Cash Equivalents and Restricted Cash

 Cash includes amounts that are either held in the Company's bank accounts or represent deposits in transit. Amounts receivable from credit card processors are considered cash equivalents because they are both short in term and highly liquid in nature and are typically converted to cash within three business days of the sales transactions.

 Restricted cash includes amounts that are held in the Company's bank accounts subject to minimum balance requirements for medical claim disbursements.

 Accounts and Tenant Improvement Receivables

 Accounts and tenant improvement receivables consist primarily of vendor rebates, tenant improvement receivables, and delivery receivables as well as receivables from related parties (Note 18. Related Party Transactions). The Company evaluates the collectability of its Accounts and tenant improvement receivables based on a variety of factors, including historical experience, current and future economic and market conditions and other factors. Based on these factors, no allowance for uncollectible accounts was recorded at December 29, 2024 or December 31, 2023.

 Inventories

 Inventories, which consists mainly of food products, is valued at the lower of cost or net realizable value, with cost determined on the first-in, first-out (FIFO) method. No other adjustment is deemed necessary to reduce inventory to lower of cost or net realizable value due to the rapid turnover and high utilization of inventory.

 The Company operates two commissaries to supply the Company's restaurants with several products and ensures product consistency and quality. The commissaries derive revenue principally from the sale and distribution of food to our distributors, who, in turn, sell the food to the restaurants. This is considered under ASC 845, Non-Monetary Transactions, and the impact on the statement of operations is not material. These products are held as inventory at distributors on a short-term consignment basis. Inventories subject to these consignment arrangements are recorded on the Company's consolidated balance sheet and were $ 0.8 million and $ 0.9 million as of December 29, 2024 and December 31,

 Portillo's Inc. Form 10-K | 46

 2023, respectively.

 Equity Method Investment

 The Company has a 50 % interest in C&O. The Company accounts for the investment and financial results in the consolidated financial statements under the equity method of accounting as the Company has significant influence but does not have control. The investment is adjusted to reflect the Company's share of C&O's earnings and losses to date and any distributions received.

 Long-Lived Assets and Valuation

 The Company's long-lived assets include property and equipment and definite-lived intangible assets. Property and equipment are recorded at cost. Internal costs directly associated with the acquisition, development and construction of a restaurant are capitalized. Expenditures for refurbishments and improvements that significantly add to the productivity capacity or extend the useful life are capitalized, while expenditures for maintenance and repairs are expensed as incurred. Leasehold improvements are amortized over the shorter of the lease term, which generally includes option periods that are reasonably certain, or the estimated useful lives of the assets. Except for leasehold improvements, depreciation is computed over the estimated useful lives of the assets (generally ranging from three to 10 years). Upon disposal of assets, the accounts are relieved of cost and accumulated depreciation and any related gain or loss is reflected in other income, net in the Company's consolidated statements of operations.

 The Company reviews its long-lived assets, including property and equipment and construction-in-progress, definite-lived intangible assets and operating lease assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group might not be recoverable. Recoverability is measured by a comparison of the carrying amount to future undiscounted cash flows that are expected to be generated by the asset or asset group. If the carrying amount exceeds its estimated future cash flows, an impairment charge is recognized in the amount by which the carrying value exceeds the estimated fair value. Restaurant-level assets are grouped by restaurant for the purpose of the impairment assessment because a restaurant represents the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. During fiscal 2024, the Company recorded a technology asset impairment charge of $ 0.7 million that was included within other income, net in the Company's consolidated statements of operations. There were no asset impairment charges recorded in fiscal 2023 and fiscal 2022.

 Goodwill and Indefinite-Lived Intangible Assets

 Goodwill and indefinite-lived intangible assets are assessed for impairment annually in the fourth quarter or more frequently if events and circumstances indicate that it is more likely than not that the fair value of a reporting unit or an intangible asset is less than its carrying value. The Company has one reporting unit which is evaluated for impairment annually. Fair value of the reporting unit is estimated using the market capitalization approach that uses publicly available market data, including publicly traded stock prices and total shares outstanding to determine the fair value of the reporting unit. If the fair value of the reporting unit is less than its carrying value, an impairment loss is recorded for the difference between the fair value of the reporting unit and the carrying value of the reporting unit.

 The Company's indefinite-lived intangible assets consist of trade names and trademarks (collectively "trade names"). The Company estimates the fair value of its trade names using a relief-from-royalty income approach. If the fair value of the trade name is less than its carrying value, an impairment loss is recorded for the difference between the estimated fair value and carrying value of the intangible assets.

 Fair Value of Financial Instruments

 The Company discloses and recognizes the fair value of its assets and liabilities using a hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. The guidance establishes three levels of the fair value hierarchy as follows:

 Level 1 - Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date;

 Level 2 - Inputs are observable, unadjusted quoted prices in active markets for similar assets or liabilities, unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the related assets or liabilities; and

 Portillo's Inc. Form 10-K | 47

 Level 3 - Unobservable inputs that are significant to the measurement of the fair value of the assets or liabilities that are supported by little or no market data.

 Revenue Recognition

 Revenues from retail restaurants are presented net of discounts and recognized when food and beverage products are sold to the end customer. Sales taxes collected from customers are excluded from revenues and the obligation is included in accrued liabilities until the taxes are remitted to the appropriate taxing authorities.

 The Company also offers delivery services to its customers. Delivery sales are generally fulfilled by third-party delivery partners whether ordered through the Portillo's app and website ("Dispatch Sales") or through third-party delivery partners ("Marketplace Sales"). Dispatch Sales include delivery and service fees as the Company controls the delivery. Revenue from Dispatch Sales is recognized when food is delivered to the customer. For these sales, the Company receives payment directly from the customer at the time of sale. Revenue for Marketplace Sales is recognized in the amount paid to the delivery partner by the customer for food and excludes delivery and service fees charged by the third-party delivery partner as the Company does not control the delivery. Revenue from Marketplace Sales is recognized when food is delivered to the customer. For these sales, the Company receives payment from the delivery partner subsequent to the transfer of order, which is generally paid one week in arrears. For all delivery sales of food, the Company is considered the principal and recognizes revenue on a gross basis.

 The Company sells gift cards which do not have expiration dates. The Company records the sale of the gift card as a contract liability and recognizes revenue from gift cards when: (i) the gift card is redeemed by the customer; or (ii) in the event a gift card is not expected to be redeemed, in proportion to the pattern of rights exercised by the customer (gift card breakage). The Company has determined that 11 % of gift card sales will not be redeemed and will be retained by us based on a portfolio assessment of historical data on gift card redemption patterns. Gift card breakage is recorded within revenues, net in the consolidated statements of operations.

 Generally, revenue is recognized as promised goods or services transfer to the guest or customer in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. Revenues are recognized when payment is tendered at the point of sale as the performance obligation has been satisfied. Refer to Note 3. Revenue Recognition for additional detail.

 Commitments

 The majority of the food products the Company purchases are subject to changes in price primarily due to the effect of supply and demand of the commodities, in particular, proteins, dairy, produce and grains. Overall pricing agreements are established in an effort to maintain a more consistent food cost without creating long-term purchase commitments.

 Employee Benefits

 The Company sponsors a 401(k) plan for all employees that are eligible based upon age and length of service. The expenses incurred for Company matching contributions to the plan were approximately $ 0.6 million, $ 0.4 million and $ 0.4 million for the years ended December 29, 2024, December 31, 2023 and December 25, 2022, respectively.

 The Company offers a non-qualified deferred compensation plan to certain officers and other members of management. Under the plan, eligible employees may defer up to 80 % of their annual salary and annual bonus. The Company has elected to fund its deferred compensation obligations through a rabbi trust. The rabbi trust is subject to creditor claims in the event of insolvency, but such assets are not available for general corporate purposes. Assets held in the rabbi trust are invested in mutual funds, which are purchased and held principally for the purpose of selling them in the near term, and are classified as trading securities and carried at fair value.

 Equity-Based Compensation

 The Company has issued non-qualified stock options, performance-based stock options, performance stock units, restricted stock units and restricted stock awards. Equity-based compensation expense is generally measured based on the grant-date fair value of those awards and is recognized on a straight-line basis over the vesting period. Equity-based compensation expense is based on awards ultimately expected to vest and is reduced for estimated forfeitures. Forfeitures are revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates and an adjustment to equity-based compensation expense will be recognized at that time. We have also granted equity awards with performance vesting conditions. Equity awards with performance or market vesting conditions generally vest based on our attainment versus stated targets or criteria over a three-year performance and service period. Performance goals are determined by the Board and include

 Portillo's Inc. Form 10-K | 48

 measures such as revenue and adjusted EBITDA growth. Compensation expense on stock awards subject to performance conditions, which is based on the quantity of awards we have determined are probable of vesting, is recognized over the longer of the estimated performance goal attainment period or time vesting period. Equity-based compensation expense is included within general and administrative expenses and labor in the consolidated statements of operations. Refer to Note 13. Equity-Based Compensation for additional detail.

 The Company adopted an Employee Share Purchase Plan ("ESPP") in June 2022 under which qualifying employees may be granted purchase rights to the Company's common shares at not less than 85 % of the market price on the purchase date, subject to Company discretion. The ESPP has a maximum of 250,000 shares of the Company's Class A common stock available for issuance. Eligible employees are able to contribute up to 15 % of their gross base earnings for purchases under the ESPP through regular payroll deductions, subject to an annual maximum dollar amount. The expense incurred under the ESPP for the years ended December 29, 2024, December 31, 2023 and December 25, 2022, was immaterial. The expense is included within general and administrative expenses and labor in the consolidated statement of operations.

 Advertising and Marketing Expenses

 Advertising costs are expensed the first-time advertising takes place, while the costs of producing advertising are expensed during production and the costs of communicating advertising are expensed as services are received. Advertising and marketing expenses totaled $ 8.0 million, $ 5.9 million and $ 4.0 million for the years ended December 29, 2024, December 31, 2023 and December 25, 2022, respectively. Advertising and marketing expenses included in other operating expenses in the consolidated statements of operations primarily relate to sponsorships, restaurant merchandising and charitable giving; and those expenses included in general and administrative expenses in the consolidated statements of operations primarily consist of regional advertising and branding initiatives. The year-over-year change for 2024 is primarily related to an advertising campaign in the Arizona market in the first quarter of 2024 and in the Chicagoland market in the third and fourth quarters of 2024.

 Cloud-Based Software Implementation Costs

 The Company has entered into cloud-based software hosting arrangements for which it incurs implementation costs. Certain costs incurred during the application development stage are capitalized and included within prepaid expenses or other assets, depending on the long or short-term nature of such costs, in line with the Company's policy on the accounting for prepaid software hosting arrangements. Costs incurred during the preliminary project stage and post-implementation stage are expensed as incurred. Capitalized cloud-based software implementation costs are amortized, beginning on the date the related software or module is ready for its intended use, on a straight-line basis over the remaining term of the hosting arrangement as a component of general and administrative expenses, the same line item as the expense for the associated hosting arrangement.

 As of December 29, 2024, the Company had $ 3.4 million of capitalized cloud-based software implementation costs made up of $ 0.9 million recorded within prepaid expenses and $ 2.5 million recorded within other assets. As of December 31, 2023, the Company had $ 2.0 million of capitalized cloud-based software implementation costs made up of $ 0.3 million recorded within prepaid expenses and $ 1.7 million recorded within other assets related to its enterprise resource planning ("ERP") and human capital management ("HCM") systems.

 Leases

 The Company currently leases land for its retail restaurants and commissaries, and office space under various long-term operating lease agreements that expire on various dates through 2068. We also lease equipment, which primarily consists of restaurant equipment and copiers. We have immaterial short-term operating leases, such as those for seasonal rentals and training spaces. We evaluate the contracts to determine whether the contract involves the use of property or equipment, which is either explicitly or implicitly identified. We evaluate whether we control the use of the asset, which is determined by assessing whether we obtain substantially all economic benefits from the use of the asset, and whether we have the right to direct the use of the asset. If these criteria are met and we have identified a lease, we account for the contract under the requirements of ASC 842.

 Upon the possession of a leased asset, we determine its classification as an operating or finance lease. As of December 29, 2024, all of our leases are classified as operating leases. Operating lease assets and liabilities are recognized at the lease commencement date. We make judgments regarding the probable term for each lease, which can impact the classification and accounting for a lease as operating or financing, as well as the amount of straight-line rent expense in a particular period. Generally, the leases for the Company's restaurant locations have an initial term of 10 years to 20 years and typically provide for renewal options in five-year increments, as well as rent escalations. Renewal options are generally recognized as part of the right-of-use assets and lease liabilities as it is reasonably certain at commencement date that we would

 Portillo's Inc. Form 10-K | 49

 exercise the options to extend the lease. Some of our real estate leases provide for base rent, plus if applicable, additional rent based on gross sales, as defined in each lease agreement, which is considered to be variable rent. When the achievement of such sales thresholds are deemed to be probable, contingent rent is accrued in proportion to the sales recognized during the period. For operating leases that include rent holidays and rent escalation clauses, we recognize lease expense on a straight-line basis over the lease term from the date we take possession of the leased property. Lease expense incurred before a restaurant opens is recorded in pre-opening expenses in the consolidated statements of operations. Once a restaurant opens, we record the straight-line lease expense and any contingent rent, if applicable, in occupancy on the consolidated statements of operations. Many of our leases also require us to pay real estate taxes, common area maintenance costs and other occupancy costs which are included in occupancy, other operating expenses, or pre-opening expenses on the consolidated statements of operations, which are generally considered to be variable rent. For leases with a lease term of 12 months or less ("short-term operating lease"), any fixed lease payments are recognized on a straight-line basis over such term, and are not recognized on the consolidated balance sheets.

 Per the ASC 842 requirements, a lessee is required to use the rate implicit in the lease when readily determinable; alternatively, it would use the incremental borrowing rate in determining the present value of future lease payments. We estimate our incremental borrowing rates corresponding to the maturities of our leases. We estimate this rate based on prevailing financial market conditions, indications for the Company's credit rating, and other benchmarks related to the Company's outstanding secured borrowings.

 We expend cash for leasehold improvements to build out our leased premises. Generally, a portion of the leasehold improvements and building costs are reimbursed by our landlords as landlord incentives pursuant to agreed-upon terms in our lease agreements. If obtained, landlord incentives usually take the form of cash, full or partial credits against our future minimum or contingent rents otherwise payable by us, or a combination thereof. In most cases, the tenant improvement allowances are received after we take possession of the property, as we meet required milestones during the construction of the property. We include these amounts in the measurement of the initial operating lease liability, which are also reflected as a reduction to the initial measurement of the right-of-use asset.

 Pre-Opening Expenses

 Pre-opening expenses consist primarily of wages, occupancy expenses, which represent rent expense recognized during the period between the date of possession of the restaurant facility and the restaurant opening date, travel for the opening team, food, beverage, and the initial stocking of operating supplies. These are expensed as incurred prior to the restaurant opening for business.

 Income and Other Taxes

 We account for income taxes pursuant to the asset and liability method which requires the recognition of deferred income tax assets and liabilities related to the expected future tax consequences arising from temporary differences between the carrying amounts and tax bases of assets and liabilities based on enacted statutory tax rates applicable to the periods in which the temporary differences are expected to reverse. Any effects of changes in income tax rates or laws are included in income tax expense in the period of enactment. A valuation allowance is recognized if we determine it is more likely than not that all or a portion of a deferred tax asset will not be recognized. In making such determination, the Company considers all available evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, prudent and feasible tax planning strategies and recent and expected future results of operations. The assumptions utilized in determining future taxable income require significant judgment and are consistent with the plans and estimates we use to manage our business. Actual operating results in future years could differ from our current assumptions, judgments and estimates, which could have a material impact on the amount of deferred tax assets we ultimately realize.

 On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act') was signed into law. The CARES Act intended to provide economic relief to those impacted by the COVID-19 pandemic. The CARES Act also allowed eligible employers to defer the remittance of employer federal payroll taxes otherwise payable during calendar year 2020 and remit half of such deferred amounts on or before December 31, 2021 and half on or before December 31, 2022. The Company deferred approximately $ 5.4 million of federal payroll tax remittances under this provision as of December 27, 2020, of which $ 2.7 million was paid during the year ended December 26, 2021 and the remaining deferred balance of $ 2.7 million was paid during the year ended December 25, 2022.

 The Company is party to a Tax Receivable Agreement ("TRA") with certain pre-IPO LLC Members that provides for the payment by the Company of 85 % of the amount of tax benefits, if any, that Portillo's Inc. actually realizes or in some cases is deemed to realize as a result of certain transactions. We account for the TRA liability in accordance with ASC 450 - Contingencies. Amounts payable under the TRA are contingent upon, among other things, (i) generation of future taxable income over the term of the TRA and (ii) future changes in tax laws. If we

 Portillo's Inc. Form 10-K | 50

 do not generate sufficient taxable income in the aggregate over the term of the TRA to utilize the tax benefits, then we would not be required to make the related TRA payments. Therefore, we would only recognize a liability for TRA payments if we determine it is probable that we will generate sufficient future taxable income over the term of the TRA to utilize the related tax benefits. The timing and amount of aggregate payments due under the TRA may vary based on a number of factors, including the amount and timing of taxable income generated by Portillo's OpCo each year and the applicable tax rates.

 The amounts recorded for both the deferred tax assets and the liability for the Company's obligations under the TRA will be estimated at the time of any purchase or exchange as a reduction to stockholders' equity, and the effects of changes in any of the Company's estimates after this date will be included in net income or loss. Similarly, the effect of subsequent changes in the enacted tax rates will be included in net income or loss.

 Earnings (Loss) Per Share

 Basic earnings (loss) per share is calculated by dividing the net income (loss) attributable to common shareholders by the weighted-average number of shares outstanding.

 Diluted earnings (loss) per share adjusts the basic earnings (loss) per unit attributable to shareholders and the weighted-average number of units of shares outstanding for the potential dilutive impact of shares, using the treasury-stock method. Diluted earnings (loss) per share considers the impact of potentially dilutive securities except in periods in which there is a loss because the inclusion of the potential common units would have an anti-dilutive effect.

 Recently Issued Accounting Standards

 In October 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC's Disclosure Update and Simplification Initiative, which amends the disclosure or presentation requirements related to various subtopics in the FASB Accounting Standards Codification (the "Codification"). The effective date for each amendment will be the date on which the SEC's removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective, with early adoption prohibited. If, by June 30, 2027, the SEC has not removed the applicable requirement from Regulation S-X or Regulation S-K, the pending content of the related amendment will be removed from the Codification and will not become effective for any entity. The Company is currently evaluating the effect of adopting this ASU.

 In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740) Improvements to Income Tax Disclosures, which requires public entities to disclose specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold on an annual basis. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the effect of adopting this ASU.

 In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires disaggregation of certain expense captions into specified categories in disclosures within the footnotes to the financial statements. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and interim periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the effect of adopting this ASU.

 Recently Adopted Accounting Standards

 In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848) Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The pronouncement provides temporary optional expedients and exceptions to the current guidance on contract modifications and hedge accounting to ease the financial reporting burden related to the expected market transition from the London Interbank Offered Rate ("LIBOR") and other interbank offered rates to alternative reference rates. The guidance was effective upon issuance and generally can be applied to applicable contract modifications through December 31, 2022. FASB has extended the sunset date to December 31, 2024. The impact of the transition from LIBOR to alternative reference rates was not material to the Company's consolidated financial statements.

 In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280) Improvements to Reportable Segment Disclosures, which requires public entities to disclose information about their reportable segments' significant expenses on an interim and annual basis. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15,

 NOTE 6. GOODWILL & INTANGIBLE ASSETS

 The Company has one reporting unit for goodwill, which is evaluated for impairment annually in the fourth quarter of each fiscal year. The Company used the market approach to test goodwill. The market approach utilized publicly available market data, including publicly traded stock prices and total shares outstanding to determine the fair value of the reporting unit.

 For indefinite-lived intangibles, the relief-from-royalty method estimates the fair value of an intangible asset based on what a third-party would pay for the right to use that asset. The most significant assumptions utilized in the relief-from-royalty method are projected revenues and the royalty rate.

 No impairment charges were recognized for goodwill or indefinite-lived intangible assets for the years ended December 29, 2024, December 31, 2023 and December 25, 2022.

 NOTE 7. FAIR VALUE OF FINANCIAL INSTRUMENTS

 Assets and Liabilities Measured at Fair Value on a Recurring Basis

 The carrying value of the Company's cash and cash equivalents and restricted cash, accounts and tenant improvement receivables, accounts payable and all other current assets and liabilities, approximate fair values due to the short-term nature of these financial instruments.

 Other assets consists of long-term prepaid expenses and a deferred compensation plan with related assets held in a rabbi trust. Other long-term liabilities consist of a deferred gain on a supplier arrangement. Long-term prepaid expenses and other long-term liabilities approximate fair values due to the nature of these financial instruments.

 Deferred Compensation Plan - The Company maintains a rabbi trust to fund obligations under a deferred compensation plan. Amounts in the rabbi trust are invested in mutual funds, which are designated as trading securities carried at fair value. The fair value measurement of these trading securities is considered Level 1 of the fair value hierarchy as they are measured using quoted market prices.

 As of December 29, 2024 and December 31, 2023, the fair value of the mutual fund investments and deferred compensation obligations were as follows (in thousands):

 Refer to Note 9. Debt for additional information relating to the fair value of the Company's outstanding debt instruments.

 Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis

 Assets and liabilities that are measured at fair value on a non-recurring basis include property and equipment, net, operating lease assets, equity-method investment, goodwill and indefinite-lived intangible assets. These assets are measured at fair value whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. During fiscal 2024, the Company recognized an impairment charge of $ 0.7 million related to a technology asset that is included within other income, net in the consolidated statement of operations. No asset impairment charges were recorded in fiscal 2023 or fiscal 2022.

 Holders of shares of our Class A common stock are entitled to one vote for each share held of record on all matters on which shareholders are entitled to vote generally, including the election or removal of directors. Holders of shares of our Class A common stock are entitled to receive dividends when and if declared by our Board out of funds legally available therefor, subject to any statutory or contractual restrictions on the payment of dividends and to any restrictions on the payment of dividends imposed by the terms of any outstanding preferred stock.

 Amended and Restated LLC Agreement

 In connection with the IPO, we amended and restated the limited liability company agreement of Portillo's OpCo ("LLC Agreement") to, among other things, convert all outstanding equity interests into LLC Units.

 The LLC Agreement also provides that holders of LLC Units may, from time to time, redeem all or a portion of their LLC Units for newly-issued shares of Class A common stock on a one -for-one basis. Upon receipt of a redemption request, we may, instead, elect to effect a direct exchange of LLC Units directly with the holder. In connection with any redemption or exchange, we will receive a corresponding number of LLC

 Portillo's Inc. Form 10-K | 59

 NOTE 12. NON-CONTROLLING INTERESTS

 We are the sole managing member of Portillo's OpCo, and as a result, consolidate the financial results of Portillo's OpCo. We report a non-controlling interest to reflect the entitlement of the pre-IPO LLC Members who retained their equity ownership in Portillo's OpCo (the "pre-IPO LLC Members"). Changes in our ownership interest in Portillo's OpCo while we retain our controlling interest in Portillo's OpCo will be accounted for as equity transactions. As such, future redemptions or direct exchanges of LLC Units in Portillo's OpCo by the pre-IPO LLC members will result in a change in ownership and reduce the amount recorded as non-controlling interest and increase additional paid-in capital.

 NOTE 13. EQUITY-BASED COMPENSATION

 2021 Equity Incentive Plan

 In connection with the IPO, the Company adopted the 2021 Equity Incentive Plan (the "2021 Plan"). The 2021 Plan is administered and interpreted by the Company's Board, including the authority to select participants in the 2021 Plan, determine the form and substance of awards under the 2021 Plan, determine the conditions and restrictions, if any, subject to which such awards will be made, modify the terms of awards, accelerate the vesting of awards, and make determinations regarding a participant's termination of employment or service for purposes of an award. The types of awards available under the 2021 Plan include stock options (both incentive and non-qualified), stock appreciation rights ("SARs"), restricted stock awards ("RSAs"), restricted stock units ("RSUs"), and stock-based awards. Employees, officers, non-employee directors or any natural person who is a consultant or other personal service provider to the Company or any of its subsidiaries or affiliates are eligible to participate in the 2021 Plan. All awards granted to participants under the 2021 Plan will be represented by an award agreement. Approximately 7.1 million shares of Class A common stock were authorized for awards under the 2021 Plan.

 Restricted Stock Units

 An RSU granted under the 2021 Plan will give the participant a right to receive, upon vesting and settlement of the RSUs, one share per vested unit or an amount per vested unit equal to the fair market value of one share as of the date of determination. The fair value of RSUs is determined using the Company's closing stock price on the date of grant. Outstanding time-based RSUs generally vest equally over periods ranging from one to three years on each of the anniversaries of the date of grant subject to continued service on such date.
 Activity for the Company's RSUs was as follows:

 Restricted Stock Awards

 On December 23, 2022, the Company granted 57,870 restricted stock awards ("RSAs") to certain of its executive officers in recognition of their work and accomplishments in 2022. The RSAs vested immediately upon grant with certain transfer restrictions. RSAs surrendered to fulfill withholding tax obligations were not subject to any transfer restrictions, and 50 % of the balance of the underlying shares were subject to a one-year holding requirement, and the balance of underlying shares was subject to a two-year holding requirement. The fair value of the RSAs surrendered was determined using Portillo's closing stock price on the date of grant, which was $ 17.19. The fair value of the awards with post-vesting restrictions was determined using the Black-Scholes option pricing model and the weighted average assumptions were as follows:

 No RSAs were issued during the years ended December 29, 2024 and December 31, 2023.

 Performance Stock Options

 The Company has granted performance stock options ("PSOs") to certain executive officers that will be eligible to vest in three (3) tranches based on stock performance conditions (i) one-third (1/3rd) of the PSOs will vest on the third anniversary of the IPO if the 20 -day volume-weighted average price ("VWAP") for a share of common stock is $ 30.00 per share ( 1.5 times the IPO price) measured over any twenty ( 20) consecutive trading day period commencing on the second anniversary of the IPO and ending on the last trading day immediately preceding the third anniversary of the IPO; (ii) one-third (1/3rd) of the PSOs will vest on the fourth anniversary of the IPO if the 20 -day VWAP for a share of common stock is $ 40.00 per share ( 2 times the IPO price) measured over any twenty ( 20) consecutive trading day period commencing on the third anniversary of the IPO and ending on the last trading day immediately preceding the fourth anniversary of the IPO; and (iii) one-third (1/3rd) of the PSOs will vest on the fifth anniversary of the IPO if the 20 -day VWAP for a share of common stock is $ 50.00 per share ( 2.5 times the IPO price) measured over any twenty ( 20) consecutive trading day period commencing on the fourth anniversary of the IPO and ending on the last trading day immediately preceding the fifth anniversary of IPO. All PSOs are subject to continued service at each tranche date and if any tranches fail to vest, the unvested portion of such PSOs will be forfeited and will not be eligible to vest in subsequent years. The awards granted are exercisable within a 10-year period from the date of grant. The first tranche of PSOs was forfeited in fiscal 2024 as the performance condition was not satisfied by the third anniversary of the IPO.
 The grant date fair value of these awards was determined using a Monte-Carlo simulation model. The fair value and weighted average assumptions used to estimate the fair value of these PSOs were as follows:

 Performance Stock Units

 During the year ended December 29, 2024, the Company granted performance stock units ("PSUs") to its executive officers under the 2021 Plan. The fair value of these awards was determined using the Company's closing stock price on the date of the grants. These PSUs will vest after the fiscal year ending December 27, 2026 based on continued service and the achievement of performance metrics. The amount of awards that can be earned ranges from 0 % to 200 % of the number of performance stock units granted, based on the achievement of approved financial goals tied to the cumulative growth of revenue and Adjusted EBITDA over the fiscal years 2024 to 2026. Compensation expense related to the performance equity units is recognized using a straight-line method over the vesting period based on the most probable outcome of the performance conditions. The cumulative effect on current and prior periods of a change in attainment is recognized in general and administrative expenses in the consolidated statements of operations in the period of change. As of December 29, 2024, management calculated an attainment rate equal to 0 % of the number of target shares granted based on actual attainment of the internal metrics.

 2014 Equity Incentive Plan

 Prior to the IPO, the Company had granted stock options under its 2014 Equity Incentive Plan, as amended (the "2014 Plan"). The 2014 Plan permitted the granting of awards to employees, officers, directors and consultants of the Company and affiliates in the form of options, unit appreciation rights, Restricted Class A Units, unrestricted Class A Units, Performance Awards and awards convertible into or otherwise based on Class A Units. Prior to the IPO, the 2014 Plan gave broad powers to the Company's board of managers for its administration and interpretation, including the authority to select the individuals to be granted awards and rights to prescribe the particular form and conditions of each award to be granted. Under the 2014 Plan, the number of shares and exercise price of each option were determined by the board of managers, or a committee designated by the board of managers. The awards granted were generally exercisable within a 10-year period from the date of grant.

 The unit option grants were equally divided between (i) options subject to time-based vesting, and (ii) options subject to both time-based and performance-based vesting. The time-based vesting options vest, in general, in equal annual installments over a 5-year period and have a 10-year term from the date of the grant. The options subject to both time-based and performance-based vesting have a ten-year term from the date of the grant and vest, in general, in equal annual installments over a 5-year period from the date of grant, subject to acceleration in the event of a sale transaction, and have a performance condition that is satisfied upon achievement of a specified internal rate of return and a minimum multiple of invested capital. In connection with the IPO, the performance condition was waived and all such options became subject to time-based vesting only.

 Following the IPO, no further options will be granted under the 2014 Plan.

 The Company's Chief Operating Officer, Mr. Derrick Pratt, departed from his role, effective June 30, 2024. In accordance with the Company's Senior Executive Severance Plan, Mr. Pratt's pre-IPO nonqualified stock options and his RSUs, both of which were scheduled to vest later in 2024, vested in the second quarter of 2024. The pre-IPO Options will remain exercisable through the 10 th anniversary of the original grant date of September 14, 2020. The primary modification was to extend the permitted time for which the options could be exercised subsequent to termination, from 90 days post-termination to the 10 th anniversary of the original grant date. All other equity grants were forfeited. The Company recorded a $ 0.2 million charge to equity-based compensation expense during the second quarter of 2024, to reflect the incremental value related to the modifications described herein.
 Employee Stock Purchase Plan

 During the fiscal year ended December 29, 2024, the Company issued 46,959 shares under the Employee Stock Purchase Plan ("ESPP"). The shares issued under the ESPP are net of shares withheld for taxes. As of December 29, 2024, 163,607 shares remained available for issuance under the ESPP. The expense incurred under the ESPP for the fiscal years ended December 29, 2024, December 31, 2023 and December 25, 2022, was immaterial.

 Our effective income tax rates for the years ended December 29, 2024, December 31, 2023 and December 25, 2022 were 16.2 %, 11.5 % and 9.6 %, respectively. The change in our effective income tax rate from the year ended December 29, 2024 to the year ended December 31, 2023 was primarily driven by an increase in the Company's ownership interest in Portillo's OpCo, which increases its share of taxable income (loss) of Portillo's OpCo, partially offset by the decrease in the valuation allowance. The Company's annual effective tax rate for the year ended December 29, 2024, December 31, 2023 and December 25, 2022 differs from the statutory rate of 21% primarily because the Company is not liable for income taxes on the portion of OpCo's earnings that are attributable to non-controlling interests, deferred tax adjustments, impacts from equity-based award activity and the change in valuation allowance.

 As described in Note 1. Description of Business and Note 11. Stockholders' Equity, we acquired LLC Units in connection with the IPO and Transactions and Secondary Offerings. During the years ended December 29, 2024 and December 31, 2023, we recognized a deferred tax asset in the amount of $ 63.9 million and $ 73.6 million, respectively, associated with the basis difference in our investment in Portillo's OpCo from acquiring these LLC Units.
 During the years ended December 29, 2024 and December 31, 2023, we also recognized deferred tax assets in the amount of $ 78.5 million and $ 71.5 million, respectively, related to additional tax basis increases generated from expected future payments under the TRA and related deductions for imputed interest on such payments.

 We evaluate the realizability of our deferred tax assets on a quarterly basis and establish valuation allowances when it is more likely than not that all or a portion of a deferred tax asset may not be realized. During the years ended December 29, 2024 and December 31, 2023, the Company recognized deferred tax assets of $ 63.9 million and $ 73.6 million, respectively, associated with the basis difference in its investment in Portillo's OpCo from acquiring these LLC Units. However, a portion of the total basis difference will only reverse upon the eventual sale of its interest in Portillo's OpCo, which we expect would result in a capital loss which we do not expect to be able to utilize. As of December 29, 2024 and December 31, 2023, the Company recorded a valuation allowance in the amount of $ 7.2 million and $ 9.2 million, respectively, against the deferred tax asset.

 As of December 29, 2024 and December 31, 2023, the Company had federal and state net operating loss carry forwards of $ 47.0 million and $ 38.7 million, respectively, available to reduce future taxable income, if any. Federal losses that arose prior to 2018 will begin to expire in 2034. Federal losses generated after 2017 will be carried forward indefinitely. The majority of state losses will begin to expire in 2034 and future periods.

 Unrecognized Tax Benefits
 The Company recorded no unrecognized tax benefits as of December 29, 2024 and December 31, 2023. Portillo's Inc. was formed in June 2021 and did not engage in any operations prior to the IPO and Transactions. Portillo's has filed all income tax returns for tax years through 2023. These returns are subject to examination by taxing authorities for U.S. federal and state income tax purposes. Additionally, although Portillo's OpCo is treated as a partnership for U.S. federal and state income taxes purposes, it is still required to file an annual U.S. Return of Partnership Income, which is subject to examination by the Internal Revenue Service ("IRS"). As of December 29, 2024, there are no ongoing U.S. federal, state or local income tax return examinations.

 Pursuant to the Company's election under section 754 of the Internal Revenue Code (the "Code"), the Company expects to obtain an increase in its share of the tax basis in the net assets of Portillo's OpCo when LLC Units are exchanged by other members. The Company intends to treat any exchanges of LLC Units as direct purchases of LLC Units for U.S. federal income tax purposes. These increases in tax basis may reduce the amounts that would otherwise be paid in the future to the U.S. federal, state and local authorities. These increases may also decrease gains (or increase losses) on future dispositions of certain assets to the extent tax basis is allocated to those assets. Also, see Note 19. Subsequent Events for information about amendments to the Tax Receivable Agreement.
 In the fourth quarter of 2024, in connection with the pre-IPO LLC Members unit redemption previously discussed in Note 1. Description of

 Portillo's Inc. Form 10-K | 67

 Business, 840,992 LLC Units were redeemed for newly-issued shares of Class A common stock. As a result, an increase in the tax basis of net assets of Portillo's OpCo subject to the provisions of the TRA was recorded. The Company recorded a deferred tax asset of $ 1.7 million and an additional TRA liability of $ 4.3 million.
 In the first quarter of 2024, in connection with the Q1 2024 Secondary Offering previously discussed in Note 1. Description Of Business, 5,832,371 LLC Units were redeemed by the pre-IPO LLC Members for newly-issued shares of Class A common stock. As a result, an increase in the tax basis of net assets of Portillo's OpCo subject to the provisions of the TRA was recorded. The Company recorded a deferred tax asset of $ 17.8 million and an additional TRA liability of $ 33.7 million.
 In the first quarter of 2023, in connection with the secondary offering previously discussed in Note 1. Description Of Business, 5,893,600 LLC Units were redeemed by the pre-IPO LLC Members for newly-issued shares of Class A common stock, resulting in an increase in the tax basis of net assets of Portillo's OpCo subject to the provisions of the TRA. The Company recorded a deferred tax asset of $ 34.9 million and an additional TRA liability of $ 47.4 million.
 As of December 29, 2024, we estimate that our obligation for future payments under the TRA totaled $ 324.6 million. The Company made payments of $ 4.4 million under the TRA during the year ended December 29, 2024 relating to tax year 2021 and we expect a payment of $ 7.7 million relating to tax year 2022 to be made within the next 12 months. Refer to Note 2. Summary Of Significant Accounting Policies for additional information on the TRA.

 NOTE 15. EARNINGS PER SHARE

 NOTE 16. CONTINGENCIES

 The Company is party to legal proceedings and potential claims arising in the normal conduct of business, including claims related to employment matters, contractual disputes, customer injuries, and property damage. Although the ultimate outcome of these claims and lawsuits cannot be predicted with certainty, management believes that the resulting liability, if any, will not have a material effect on the Company's consolidated financial statements.

 As of December 29, 2024 and December 31, 2023, the Company recorded no loss contingencies.

 NOTE 17. SEGMENT INFORMATION

 The Company owns and operates fast-casual restaurants in the United States, along with two food production commissaries in Illinois. The Company's chief operating decision maker (the "CODM") is its Chief Executive Officer. As the CODM reviews financial performance and allocates resources at a consolidated level on a recurring basis, the Company has one operating segment and one reportable segment.

 The CODM allocates resources and assesses performance of the Company based on net income (loss), as reported on the Consolidated Statement of Operations, which as the segment measure of profit and loss that is closest to GAAP, is the required segment measure. Net income was $ 35.1 million, $ 24.8 million, and $ 17.2 million for the fiscal years ended December 29, 2024, December 31, 2023, and December 25, 2022, respectively. In addition to net income (loss), the CODM also reviews operating income (loss), restaurant-level adjusted EBITDA and adjusted EBITDA.

 The CODM reviews these measures (i) to evaluate the Company's operating results and the effectiveness of business strategies, (ii) internally as benchmarks to compare the Company's performance to its competitors and (iii) as factors in evaluating management's performance when determining incentive compensation. Additionally, the Company believes these measures are important to evaluate the performance and profitability of our restaurants, individually and in the aggregate.

 The CODM does not review segment assets and segment expenses at a level different than what is reported in the Company's Consolidated Balance Sheet and Consolidated Statement of Operations. Additionally, the CODM regularly receives information about the Company's capital expenditures which are reported in the Company's Consolidated Statement of Cash Flows as Purchase of property and equipment under investing activities.

 No guest accounts for 10% or more of our revenues.

 NOTE 18. RELATED PARTY TRANSACTIONS

 As of both December 29, 2024 and December 31, 2023, the related parties' receivables balance consisted of $ 0.3 million, due from C&O, which is included in accounts and tenant improvement receivables in the consolidated balance sheet.

 NOTE 19. SUBSEQUENT EVENTS

 Management evaluated events occurring subsequent to December 29, 2024 and other than as noted below determined that no material recognizable subsequent events occurred.

 2025 Credit Agreement Closing

 On January 27, 2025 (the "2025 Credit Agreement Closing Date"), Holdings, the Borrower, the other Guarantors party thereto, the Lenders from time to time party thereto and Fifth Third Bank, National Association, as Administrative Agent, the L/C Issuer and the Swing Line Lender entered into an amendment (the "Amendment") to the 2023 Credit Agreement (as amended by the Amendment and as may be amended, restated, supplemented or otherwise modified from time to time thereafter, the "2025 Credit Agreement"). Capitalized terms used but not defined in this Note 19 have the meaning ascribed to such terms in the Amendment or the 2025 Credit Agreement, as applicable.

 The Amendment provides for, among other things, (i) a $ 250 million term loan A facility (the "2025 Term Loan Facility") and (ii) revolving credit commitments in an initial aggregate principal amount of $ 150 million (the "2025 Revolving Credit Facility" and, together with the Term Loan Facility, the "2025 Facilities"), the proceeds of which will be used to refinance indebtedness under the 2023 Credit Agreement, for general

 Portillo's Inc. Form 10-K | 70

 corporate purposes and working capital needs and for other activities permitted under the 2025 Credit Agreement.

 The loans under each of the 2025 Facilities mature on January 27, 2030. The 2025 Facilities are guaranteed, subject to customary exceptions, by all of the Borrower's wholly-owned domestic restricted subsidiaries and Holdings, and are secured by a lien on substantially all of the Borrower's assets, including fixed assets and intangibles, and the assets of the Guarantors, in each case, subject to customary exceptions. The Borrower may, upon notice to the Administrative Agent by the Borrower, at any time or from time to time voluntarily prepay the 2025 Term Loan Facility or the 2025 Revolver Facility in whole or in part without premium or penalty.

 The 2025 Term Loan Facility is subject to amortization of principal, payable in quarterly installments on the last day of each fiscal quarter, commencing on the last day of the first full fiscal quarter after the Closing Date (the "Initial Amortization Date"), equal to (i) for the first two years following the 2025 Credit Agreement Closing Date, $ 6.3 million of the original principal amount of the term loans, (ii) for the third and fourth years following the 2025 Credit Agreement Closing Date, $ 12.5 million of the original principal amount of the term loans and (iii) for the fifth year following the 2025 Credit Agreement Closing Date, $ 25.0 million of the original principal amount of the term loans. The remaining initial aggregate advances under the Term Loan Facility are payable at the maturity of the 2025 Term Loan Facility.

 Each Facility bears interest at a rate per annum equal to, (i) in the case of Base Rate Loans, an applicable rate based on a grid ranging from 1.00 % to 1.75 % or, (ii) in the case of Tranche Rate Loans, an applicable rate based on a grid ranging from 2.00 % to 2.75 %, in each case, based on the Consolidated Total Net Rent Adjusted Leverage. In addition, the Borrower will pay (i) an unused commitment fee of between 0.20 % and 0.25 % on the undrawn commitments under the 2025 Revolving Credit Facility and (ii) Letter of Credit fees of between 2.00 % and 2.75 % on outstanding Letters of Credit, in each case, also based on the Consolidated Total Net Rent Adjusted Leverage.

 The 2025 Credit Agreement contains customary representations and warranties, events of default, reporting and other affirmative covenants and negative covenants, including limitations on indebtedness, liens, investments, negative pledges, dividends, junior financings and other fundamental changes. Failure to comply with these covenants and restrictions could result in an event of default under the 2025 Credit Agreement. In such an event, all amounts outstanding under the 2025 Credit Agreement, together with any accrued interest, could then be declared immediately due and payable.

 2025 Tax Receivable Agreement Amendment

 On January 24, 2025, we entered into an Amendment to the Tax Receivable Agreement (the "Amendment") with PHD Group Holdings, LLC and the TRA Party Representative, as defined in the agreement. The Amendment replaces the LIBOR based interest rate with a Term Secured Overnight Financing Rate ("SOFR") based rate.

 New Director

 On January 9, 2025, the Board elected Jack Hartung to serve on the Company's board of directors, ( the "Board"), effective immediately. In connection with his appointment, Mr. Hartung was appointed to serve on the Audit Committee of the Board.

 ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURES

 None.

 ITEM 9A. CONTROLS AND PROCEDURES

 EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES

 Under the supervision and with the participation of our management, including the Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of such date. Our disclosure controls and procedures are designed to ensure that information required to be disclosed in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms and that such information is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer, to allow for timely decisions regarding required disclosure.

 CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING

 There were no changes to our internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) that occurred during the quarter ended December 29, 2024 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

 MANAGEMENT'S ANNUAL REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

 The management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f).

 Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

 Under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, management conducted an assessment of the effectiveness of the Company's internal control over financial reporting as of December 29, 2024 based on the framework established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, management has determined that the Company's internal control over financial reporting was effective as of December 29, 2024.

 Our independent registered public accounting firm, Deloitte & Touche LLP, has issued an attestation report on the effectiveness of our internal control over financial reporting as of December 29, 2024, as stated in their report herein.

 Portillo's Inc. Form 10-K | 73

 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

 To the stockholders and the Board of Directors of Portillo's Inc.

 Opinion on Internal Control over Financial Reporting

 We have audited the internal control over financial reporting of Portillo's Inc. and subsidiaries (the "Company") as of December 29, 2024, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 29, 2024, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.

 We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 29, 2024, of the Company and our report dated February 25, 2025, expressed an unqualified opinion on those financial statements.

 Basis for Opinion

 The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

 We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

 Definition and Limitations of Internal Control over Financial Reporting

 A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

 Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
