&nbsp;&nbsp;**Letter to<br>Shareholders**<br>

**A Letter from our Chairman, Gene Lee**

Dear Fellow Shareholders,

On behalf of the Board of Directors, I want to thank you for your investment and belief in the Portillo's story. We had a pivotal year in 2025, including key leadership changes and the announcement of a strategic reset of our growth and development approach. In 2026, we've continued this spirit of transformation as the Board named Brett Patterson as President and Chief Executive Officer in February and appointed me to assume the role of Chairman in March. I am thrilled to serve in this role and feel the foundation we've built thus far has aligned our teams and energized our vision for what lies ahead.

Brett's strategic, growth-oriented mindset and unwavering commitment to operational excellence will continue to drive our Company forward. Most importantly, he demonstrates people-first leadership and fosters the type of culture that will make Portillo's successful as it enters this exciting phase of growth and development. We are very pleased to have him at the helm.

I would also like to take this opportunity to thank Mike Miles, who joined the Board as Chairman in 2014, for his dedicated service to Portillo's. Mike helped shepherd us through the IPO process and served as Interim CEO on two different occasions, most recently helping frame up the Company's strategic reset. His dedication to Portillo's over the past decade is commendable, and we wish him well in his retirement.

I also want to recognize Josh Lutzker, who likewise will not stand for reelection at the upcoming Annual Meeting. He has been an engaged, committed Director since 2014, leveraging his broad range of business perspectives and financial acumen to support Portillo's during his service. We thank Josh and wish him continued success.

With a renewed foundation in place, we enter the next chapter with momentum and confidence. Our commitment to operational excellence, coupled with a more disciplined growth plan, positions the Company to capitalize on opportunities ahead and deliver long-term value for our shareholders. I am honored to be a part of it and look forward to our exciting future.

**"With a renewed foundation in place, we enter the next chapter with momentum and confidence."**

**Message from our Former Chairman, Mike Miles** 

In 2014, when Dick Portillo turned over the reins of the company he founded, we established a number of goals for Portillo's. We wanted to expand beyond our Chicago roots, build an organization capable of supporting a scaled, national restaurant brand, and ultimately become a successful public company. But our most important objective was to remain true to the unique restaurant experience that had made Portillo's so loved by those who know us. I deeply appreciate the hard work that so many at Portillo's have put in to achieve those objectives. By every measure, Portillo's continues to be one of the most loved brands in the restaurant industry, now across more than 100 restaurants in 11 states.

The most important role of a board of directors is to ensure the company has outstanding leadership. So I take pride in passing the baton to Gene to chair the Board and to Brett as he takes on the role of CEO. Along with an exceptionally qualified group of directors, they will lead Portillo's into a future that is even brighter than its storied past. While I will be leaving the Board this spring, I will remain a committed and enthusiastic fellow shareholder. And a very frequent customer!

&nbsp;&nbsp;**Q&A with Our President and<br>Chief Executive Officer**<br>

![Brett_Patterson.jpg](ptlo-20260417_g11.jpg)

**"I look forward to building on that foundation by ensuring that we have a relentless focus on providing great guest experiences led by strong operational fundamentals, supporting our teams, and continuing to create long-term value for the business through disciplined, sustainable growth."**

**The Board of Directors recently named you as Portillo's President and Chief Executive Officer. What fueled the decision to join Portillo's?**

First, I appreciate the Board's confidence and am excited to be a part of this unique brand. What initially stood out to me was that Portillo's has a special culture led by passionate and committed Team Members focused on creating great guest experiences. It is truly one of the industry's special brands with deep customer loyalty. Lastly, Portillo's is a brand that has tremendous growth potential. It is clear this is a brand that people love and one that needs to be shared with more communities.

The Board and the management team have laid a foundation for success, particularly with the recent strategic reset. I look forward to building on that foundation by ensuring that we have a relentless focus on providing great guest experiences led by strong operational fundamentals, supporting our teams, and continuing to create long-term value for the business through disciplined, sustainable growth.

**What's your leadership philosophy, and any thoughts on your initial approach?**

I know leadership transitions can bring questions, so my priority right now is to listen and learn. I want to understand the business from the ground up, keying in on what's working and where we have opportunities to improve.

Having started my career on the front lines within restaurants, I have a deep respect for what our operators and Team Members do each and every day. Setting our teams up for success by providing a clear vision, focused strategy, and the necessary resources to excel will drive long-term success. My focus is on keeping things simple, executing disciplined business fundamentals, and making sure we're consistently delivering a great experience for our guests who have loved us for decades as well as those new to Portillo's.

As I spend more time in the business, those learnings will help shape our path forward, ensuring healthy unit economics and restaurant returns, ultimately creating long-term value for our shareholders.

**And most importantly, what's your favorite Portillo's menu item?**

For me, it has always been the Italian Beef and Sausage Combo. It's one of those craveable menu items that Portillo's knows how to do right.

**Compensation Philosophy**

The Company's compensation philosophy prioritizes performance and aims to align executive compensation with shareholders' interests while ensuring that the Company can retain key talent. To achieve this alignment, the Compensation Committee focuses on maintaining market-competitive base salaries and structuring short-term and long-term incentives to directly tie to Company performance on strategic and financial objectives within market norms. In pursuit of these goals, we implement programs that foster alignment between Team Member interests and Company objectives, cultivating a shared vision of success while mitigating undue risk. Our executive compensation policies and practices include:

---

| &nbsp;&nbsp;&nbsp;&nbsp;**•** Pay for Performance <br>&nbsp;&nbsp;&nbsp;&nbsp;**•** Alignment with Shareholder Interests <br>&nbsp;&nbsp;&nbsp;&nbsp;**•** Attracting, Retaining and Engaging Top Talent | **•** Stock Ownership and Trading Policies <br>**•** Health, Retirement and Other Benefits <br>**•** Values-Based Ethical Framework |

| **Proposal**<br>**1** | &nbsp;&nbsp;**Election of Directors** |

---

Our Board of Directors currently has nine members, each of whom, with the exception of Eugene I. Lee, Jr. and Brett Patterson, was previously elected to a one-year term at our 2025 Annual Meeting. Five Directors were appointed to our Board in September 2021 and had previously served on the Board of Directors of Portillo's OpCo; Ms. Dodson was appointed to the Board in December 2021; Mr. Hartung was appointed in January 2025; Mr. Lee was appointed in June 2025; and Mr. Patterson was appointed in February 2026. At the Annual Meeting, shareholders will only be permitted to consider the nominees below.

Acting upon the recommendation of the Nominating and Corporate Governance Committee, our Board has nominated each of Ann Bordelon, Paulette Dodson, Noah Glass, Gerard J. Hart, Jack Hartung, Brett Patterson, and Eugene I. Lee, Jr. for election to the Board to serve until our 2027 Annual Meeting of Shareholders and until the election and qualification of their respective successors in office or until such Director's earlier death, resignation or removal. Each of the Director Nominees has consented to serve if elected, however, if a nominee is unable to serve or will not serve for any reason, the Directors may decide to reduce the size of the Board or the designated proxies will vote for other candidates in accordance with their judgment. We are not aware of any reason the nominees would not be able to serve if elected.

There are no family relationships among our Directors, or between our Directors and Executive Officers.

**Voting Requirement**

Directors are elected by a plurality of the votes cast by the holders of shares present in person or represented by proxy at the Annual Meeting and entitled to vote thereon. This means the seven Directors receiving the greatest number of votes cast "FOR" their election will be elected. Because the voting standard requires nominees to win a plurality, any shares not voted "FOR" a nominee, whether such shares are voted to "WITHHOLD" or not voted as a broker non-vote, will not count. Please note, if you are a street name shareholder and do not provide voting instructions to your broker or other nominee, they will not vote your shares on this proposal.

**Director Resignation Policy; Failure to Receive Majority Vote**

Pursuant to our Corporate Governance Guidelines, any nominee for Director in an uncontested election who fails to receive a majority of the votes cast at a shareholder meeting is required to tender to the Board his or her resignation from the Board and all Committees thereof. Failure to receive the affirmative vote of a majority of votes cast means that the number of "WITHHOLD" votes for a particular nominee exceeds the number of votes "FOR" such nominee (excluding abstentions and broker non-votes). The Nominating and Corporate Governance Committee shall assess the appropriateness of such nominee continuing to serve as a Director and shall recommend to the Board the action to be taken with respect to such tendered resignation. Any Director who tenders his or her resignation pursuant to this provision shall not participate in the Nominating and Corporate Governance Committee recommendation or Board action regarding whether to accept the resignation offer. In determining whether or not to recommend that the Board accept any tendered resignation, the Nominating and Corporate Governance Committee will consider all factors believed relevant by its members.

Proposal 1 Election of Directors

**Director Independence** 

Our Nominating and Corporate Governance Committee evaluates our relationships with each Director and nominee and makes a recommendation to our Board as to whether to make an affirmative determination that such Director or nominee is independent. Our Board has affirmatively determined that each of Ms. Bordelon, Ms. Dodson, Mr. Glass, Mr. Hart, Mr. Hartung Mr. Lutzker, and Mr. Miles, subject to the qualifications below, or all of our Directors other than our CEO, Mr. Patterson, qualify as an independent Director under the applicable Nasdaq rules. Mr. Miles served as an independent director under the applicable Nasdaq rules and SEC rules and regulations for a portion of the fiscal year ended December 28, 2025 until his appointment as the Company's Interim CEO in September 2025, resigning as Interim CEO in February 2026. Mr. Miles remained a member of the Board but did not serve on the Board's Nominating and Corporate Governance Committee and Compensation Committee while he served as Interim CEO. Given that Mr. Miles served as Interim CEO for less than a 12-month period, following his resignation as Interim CEO, he rejoined the Nominating and Corporate Governance Committee and Compensation Committee as an independent member under applicable Nasdaq rules. Additionally, the Board has reviewed the additional Nasdaq independence considerations for Compensation Committee members and determined that each of Messrs. Hart and Lutzker is, and that Mr. Miles was, during his tenure on the Compensation Committee, independent for the purposes of serving on the Compensation Committee. The Board has also affirmatively determined that each of Mses. Bordelon and Dodson and Messrs. Glass and Hartung meets the definition of "independent directors" for the purpose of serving on the Audit Committee under applicable Nasdaq rules and Rule 10A-3 under the Securities Exchange Act of 1934, as amended (the "Exchange Act").

Proposal 1 Election of Directors

**Director Nomination Process**

Each year, as noted in the Company's Corporate Governance Guidelines, the Board proposes a slate of Director Nominees for election by shareholders at the Annual Meeting. The Board has delegated the process of finding and screening potential director candidates to the Nominating and Corporate Governance Committee.

| **Candidate Sourcing**<br>The Nominating and Corporate Governance Committee identifies potential candidates from a variety of sources, including shareholder recommendations, professional networks, and third-party organizations and recruitment firms. This enables the Committee to develop as strong a slate of Director Nominees as possible. In 2025, no fees were paid by the Board or Company in connection with any director search. |  | **Screening and Evaluation**<br>The Nominating and Corporate Governance Committee evaluates potential Director Nominees, including any that are recommended by shareholders, against the then-current Board's established criteria. All recommendations are considered on an equal basis, regardless of source, and go through the same review process. Candidates typically provide the Committee a completed Director questionnaire, curriculum vitae, and recommendations. Members of the Nominating and Corporate Governance Committee, along with the Chairman of the Board and the CEO, may conduct interviews with potential candidates to develop a more comprehensive understanding of the candidate's potential contributions to our Board. |  | **Board Review and Nomination**<br>If the Nominating and Corporate Governance Committee approves a candidate for further consideration, the candidate's profile is submitted to the Board for further review and discussion. Where appropriate, candidates may be interviewed by other Directors and ultimately may be appointed to the Board or nominated for election by our shareholders. |
| Ongoing Oversight and Composition Review<br>The Nominating and Corporate Governance Committee, under the leadership of its Chair, is responsible for providing direction and oversight regarding how the Company's continued growth and evolution may impact the skills and experience required of its Directors. The Nominating and Corporate Governance Committee regularly reviews the composition of the Board and its committees to ensure their composition reflects an appropriate blend of skills, experience, and perspectives aligned with and supportive of the Company's strategy. This review involves consideration of the Company's current and future strategic plans, overall performance, peer benchmarking against other companies' skills and experience matrices, and the Board's annual self-assessments to help identify Director skills, backgrounds and experience that may further bolster Board effectiveness. The Committee may seek new candidates to address identified gaps or evolving business needs, including specific industry expertise, or to refresh Board composition to meaningfully augment the current Board. In 2025, the Committee initiated a search for director candidates who would bring additional restaurant industry expertise to the Board, particularly in regard to operations. The Committee periodically reviews with the Board the appropriate criteria for Board membership (including experience, qualifications, attributes, skills and other characteristics) in the context of the Board's current composition and needs, and in light of the Company's current circumstances, future plans, and strategic initiatives. The Board seeks to ensure it maintains an appropriate balance of experience, continuity of service and fresh perspectives, and therefore it considers length of tenure when reviewing nominees. The Board does not presently impose age or term limits, but may adopt such limits if it deems them appropriate or necessary in the future. | Ongoing Oversight and Composition Review<br>The Nominating and Corporate Governance Committee, under the leadership of its Chair, is responsible for providing direction and oversight regarding how the Company's continued growth and evolution may impact the skills and experience required of its Directors.

**Re-Nomination and Board Refreshment Considerations**

The Board recognizes the importance of evaluating individual Directors and their contributions to the Board when making re-nomination decisions.

The Board of Directors gives continuous, thoughtful consideration to the composition of our Board to maintain an appropriate mix of experience and qualifications, introduce new perspectives, and broaden the views represented on the Board.

**Commitment and Limits on Other Activities**

Because of the time commitment associated with Board service, Directors are expected to limit the number of public company boards on which they serve to between three and five (including the Company's Board), with the lower limit applying to Directors who are Executive Officers of the Company or at any other public company. Directors must advise the Chair of the Board in advance of accepting an invitation to serve on another board.

Proposal 1 Election of Directors

**Change in Principal Occupation**

If a Director's principal occupation or business association changes from the position the Director originally held when invited to join the Board, the Director shall promptly submit to the Chair of the Nominating and Corporate Governance Committee an offer to resign from the Board. The Nominating and Corporate Governance Committee will review whether it would be appropriate for the Director to continue serving on the Board and recommend to the Board, in light of the circumstances, a course of action that serves the best interests of the Company. Directors are also expected to inform the Chair of the Nominating and Corporate Governance Committee and the General Counsel of the Company of other events or commitments that could reasonably be perceived to be relevant to consideration about ongoing independence or that could otherwise impact the Director's service on the Board.

**Shareholder Nominations**

The Nominating and Corporate Governance Committee values the input of shareholders in identifying prospective Director candidates. The Nominating and Corporate Governance Committee considers recommendations for Board candidates submitted by shareholders using the same criteria it applies to recommendations from the Committee, Directors, and members of the Executive Team. This criteria is described in the Nominating and Corporate Governance Committee Charter, the Company's Corporate Governance Guidelines, and in this Proxy Statement and may evolve over time to best meet the current needs of the Company. Shareholders may submit recommendations by providing the person's name and appropriate background and biographical information in writing to the attention of the Nominating and Corporate Governance Committee at 2001 Spring Road, Suite 400, Oak Brook, Illinois 60523. Invitations to serve as a nominee are extended by the Board via the Chair of the Board and the Chair of the Nominating and Corporate Governance Committee.

If shareholders wish to directly nominate a candidate, they may do so by following the instructions and deadlines set forth in the "Shareholder Proposals" section.

&nbsp;&nbsp;**Corporate**<br>**Governance**<br>

**Board and Committee Structure**

**Role of the Board**

The Board's role is to provide oversight and strategic direction to the Company's leadership team and promote and further the interests of all stakeholders in driving long-term value and sustainable success of the business. The Board does not manage the Company's day-to-day operations, which remain the responsibility of the Executive Team, but exercises oversight either directly or through its Committees. In fulfilling its role, the Board:

**•** Oversees and provides guidance to the CEO and other executives on issues of strategy and business performance

**•** Reviews and oversees the Company's long-term strategic plans, key business objectives, and risks and opportunities related to sustainability, environmental, social and governance matters

**•** Engages in CEO succession planning and guides and oversees the development of the Executive Team

**•** Reviews and approves strategic plans, providing guidance to the Executive Team in formulating corporate strategy

**•** Reviews and offers feedback on the Company's financial objectives, capital allocation priorities, and significant transactions and initiatives

**•** Designs the Company's governance framework and practices, including Board and Committee structure and composition, to support effective and efficient Board performance

**•** Oversees enterprise risk management, including financial, operational, strategic, compliance, and reputational risks

**•** Provides guidance and oversight regarding the integrity of the Company's internal controls, financial reporting, disclosure controls and procedures, and internal and external audit processes

**•** Reviews major changes in accounting principles and practices

**•** Evaluates and oversees the compensation of the CEO and other Executive Officers, including alignment of compensation with performance and long-term shareholder interests

**•** Oversees Company compliance with applicable laws and regulations, reinforcing a culture of ethics and integrity

**•** Performs such other functions as the Board considers to be appropriate or necessary to carry out its fiduciary duties

**Leadership Structure of the Board**

The positions of Chairman of the Board and Chief Executive Officer are presently separated. Our Bylaws and Corporate Governance Guidelines, which do not require that our Chair and Chief Executive Officer positions be separate, allow our Board to determine the leadership structure that is appropriate for us at any given time, taking into account the dynamic demands of our business, our Executive Team personnel, and other factors. The Board does not have a fixed policy regarding the separation of the offices of Chairman of the Board and Chief Executive Officer, and believes that it should maintain the flexibility to select the Chair and adjust its leadership structure, from time to time, based on the criteria that it deems in the best interests of the Company and its shareholders. We believe the present separation between the Chair and the Chief Executive Officer best serves the Company's present needs because it allows our Chief Executive Officer to focus on day-to-day operations, while allowing the Board Chair to guide the Board as it provides advice to and independent oversight of the Executive Team.

During those times when the Chair and the Chief Executive Officer were not the same individual, the Board determined that Mr. Miles was qualified to serve as our independent Chair because of his substantial experience leading a global retailer and distributor, operational leadership experience in the restaurant industry, public company board experience, and experience advising other companies, especially related to multi-unit operations, development, and marketing.

When the Chair and the Chief Executive Officer are the same individual, or when the Chair otherwise does not qualify as an independent Director, the independent Directors may select from among the independent Directors a lead independent Director with such responsibilities as determined by the Board. As a result, Mr. Lee was appointed to serve as the Board's Lead Independent Director during Mr. Miles' service as Interim Chief Executive Officer from September 21, 2025 to February 23, 2026. The Board determined that Mr. Lee was qualified to serve as our Lead Independent Director during that time period, and to serve as our independent Chairman beginning on March 10, 2026, due to his extensive leadership experience in and history of driving positive results throughout the restaurant industry.

**Meetings and Attendance**

The Board held fourteen meetings in 2025. Each Director attended more than 75% of the aggregate meetings of the Board and any Committees of which he or she was a member in 2025, during the time in which they served as a member of the Board and such Committees.

Directors are expected to devote sufficient time and attention to their responsibilities, such as preparing for, attending, and meaningfully participating in Board and Committee meetings, including reviewing materials distributed in advance of the meetings. Our Directors recognize that candor, integrity, and avoidance of conflicts, both actual and perceived, are essential to provide effective oversight and accountability. Where conflicts are unavoidable or involve related-party transactions that are determined to advance the best interests of the Company, Directors recognize their duty to ensure such matters are disclosed and handled through the proper approval process. These standards are the hallmarks of the Board's fiduciary responsibility to the Company and its shareholders.

Corporate Governance

**Executive Sessions**

The non-management Directors meet regularly in executive session without members of management present, including before or after Board and Committee meetings. If any of the non-management Directors do not qualify as an "independent Director," the independent Directors hold at least one additional executive session each year that is attended only by independent Directors. Executive sessions may be held in connection with both Board and Committee meetings and are conducted pursuant to agendas and procedures determined by the attending Directors, as appropriate. Any authority to act on behalf of the Company or the Board during an executive session requires an express delegation of authority from the Board.

**Board and Committee Self-Evaluations**

Our Board conducts an annual performance self-evaluation to assess the effectiveness of the Board and its Committees and to identify areas of opportunity to enhance overall performance, strengthen oversight, and optimize the value Directors bring to the Board. This evaluation process, which reflects recognized governance best practices, is built into each of the Committee charters, with primary responsibility for the coordination of the evaluation process delegated to the Nominating and Corporate Governance Committee. The evaluation process solicits feedback on a range of issues, including Board and Committee composition and structure, meeting topics and processes, organizational effectiveness, Board functions, oversight of business strategy and financial matters, and overall governance practices. The self-evaluations assist the Board in identifying additional Director skills, experience, and perspectives that may enhance Board effectiveness. The results of the self-evaluation are reviewed by the Chair of the Board and the Committee Chairs, who discuss the findings in advance of broader discussion by the full Board and each applicable Committee. As a result of the most recent Board and Committee self-evaluations, the Board and Committees identified a handful of priority areas and related action items, which will be incorporated into the Board's and Committees' 2026 agendas. The evaluation process is reviewed and refreshed annually, as appropriate, to reflect evolving governance best practices and to ensure continued focus on areas of opportunity and improvement.

**Our Board and Culture**

Portillo's culture is a key differentiator and helps to drive our results and long-term growth. Our culture embraces our core values of Family, Greatness, Energy and Fun and our efforts to instill, reinforce, and enhance our culture is deliberate and intentional.

Our Board is deeply engaged in understanding Portillo's culture. We believe our Board should have a strong understanding of our culture because it is the foundation for our Company's strategic plans and enables the Board to provide informed and honest guidance and feedback, maintaining an open dialogue with the Executive Team based on a clear understanding of the Company's strategic plans.

**Beyond the Boardroom**

The commitment of our Directors extends well beyond preparation for and participation in regularly scheduled Board meetings. Engagement outside of Board meetings provides our Directors with additional insight into our business and industry and gives them valuable perspectives on the performance of our Company, the Board, our CEO and other members of the Executive Team, as well as the Company's strategic direction.

In 2025, these sessions covered topics such as executive compensation, investor relations, and legal, legislative and regulatory issues. | &nbsp;&nbsp;The Board aims to conduct at least one off-site meeting annually to provide Directors an opportunity to view Company operations, visit new sites and restaurants, engage with Team Members, and acquire direct insights about the Company's execution of its strategic initiatives.

Corporate Governance

While the Board and Committees oversee risk management strategy, management is tasked with executing that strategy. Management works with the appropriate cross-functional teams to assess, monitor and mitigate material risks. Throughout 2025, the Company fortified its risk management efforts by conducting an enterprise risk assessment process to identify and evaluate risks that could materially impact the Company's strategic objectives and business performance. Senior leaders across the organization contributed to the assessment by identifying and assessing key risks, which were then evaluated using standardized criteria, including potential impact, likelihood, and degree of control.

In support of business continuity and operational resilience, the Company maintains a formal Incident Management Plan that is subject to ongoing review and refinement to establish clear severity levels, cross-functional coordination, and consistent response procedures for potential operational disruptions. The plan is designed to complement broader business continuity processes and provides a framework for timely and effective incident response efforts.

In parallel, the Company maintains an Information Technology Disaster Recovery Plan that is subject to ongoing review to ensure the recoverability of critical systems in the event of a disruption. The Plan outlines recovery objectives, system priorities, and procedural responsibilities. The Company also maintains Business Continuity Plans that are periodically reviewed to maintain critical operations during potential disruptions. These Plans were designed around business priorities, key dependencies, and recovery strategies, supporting resilience across essential functional areas and activities.

To further enhance preparedness, the Company conducts periodic incident management training and tabletop scenario exercises involving cross-functional teams. These exercises simulate different types of high-impact events over time, allowing participants to test response capabilities, clarify roles and responsibilities, and identify opportunities for improvement.

The 2025 risk and resilience efforts outlined were reviewed with and presented to the Audit Committee to support its ongoing oversight and governance responsibilities.

**Executive Succession Planning**

The Board and management recognize the importance of continuously developing our executive talent while engaging in thoughtful succession planning exercises, identifying potential internal and external candidates, and preparing for emergency situations that may arise. Our Compensation Committee conducts comprehensive annual talent assessments that include succession planning for the Executive Team and the Company's management development program. The Board and Compensation Committee conduct additional reviews as needed to bolster development efforts, such as executive coaching and peer reviews. The Board considers from time to time, as appropriate, potential successors to the CEO in the event of resignation, retirement or disability.

Portillo's has a robust and formal talent and succession planning program, which includes all levels of the organization. In connection with this process, the CEO reports to the Board annually and from time to time on the Company's succession planning and management development efforts. Portillo's views succession planning as an ongoing process, not an "event," and is focused on the following objectives:

**•** Develop a succession plan to support our growth strategy in addition to planning for different succession scenarios, such as emergency, accelerated and orderly transitions

**•** Link succession planning to strategy by refreshing Executive Team profiles that focus on what is most needed to lead Portillo's now and in the future

**•** Assess the readiness of current key Executive Team members to assume the responsibilities of top leadership positions and the Company's plans and timeframes for addressing any gaps in readiness

**•** Ensure that Executive Team members have clear and actionable development plans, including coaching, and establish a regular and transparent process for leadership and the Board to track and assess progress

**Shareholder Engagement and Communication with the Board**

Portillo's commitment to transparency extends to a robust shareholder engagement program. Via our integrated, internal Investor Relations function, we place a high priority on providing both reactive and proactive interaction with current and potential shareholders. We make best efforts to maintain regular, ongoing dialogue with the investment community to gather key insights on everything from Company strategy to governance practices.

Shareholders have continually provided valuable information which has led to enhancements in many areas of our business, including Board composition, capital deployment/investments, and our overall approach to restaurant growth. Portillo's took major steps in 2025, in part due to these discussions, to implement a Development reset last fall, and made adjustments in our overall strategy and leadership direction that will continue to shape the future of Portillo's.

We communicated with our shareholders, prospective investors, and other stakeholders in a variety of ways throughout the year, including through virtual meetings and in-person events hosted by us or others. Discussions primarily centered on Company results, leadership changes, macroeconomic conditions, consumer behavior and sentiment, our longer-term growth strategy, capital investment, optimization of our restaurant footprint and design, Company culture, and other restaurant industry trends and developments. We also engaged with investor groups by hosting them at our Beef Bus at ICR in January 2025 and at several of our restaurants whenever possible.

Our investor outreach also includes proactive, recurring conversations with stewardship teams and proxy, governance, and compensation practice specialists. Portillo's is committed to offering and conducting these conversations each proxy voting season, while also making ourselves available for off-season touchpoints whenever needed and upon request. Notable attendees on the Portillo's side include the CFO, Chief People Officer, General Counsel and Corporate Secretary, External Communications and Investor Relations. Our CEO and Board members also participate in select conversations with large stakeholders when available.

**Sourcing and Sustainability Initiatives**

We strive for excellence when it comes to food quality, using only ingredients that meet our stringent standards and specifications. We partner with a variety of companies similarly aligned with producing and providing high quality products, each of which goes through a comprehensive evaluation process to ensure they will satisfy our standards and expectations on a continual basis. This facilitates real-time performance assessments to identify any potential gaps in food safety or quality and implement corrective measures where required. Further, our relationships with our suppliers and distribution partners are governed by a Supplier Code of Conduct to ensure that all parties are conducting themselves in a responsible, ethical way.

We have taken a thoughtful look at our supply chain and operations to identify opportunities to embrace environmental consciousness in ways that make a difference to our guests, Team Members and shareholders.

**Director Compensation**

**Independent Director Compensation Program**

In consultation with Meridian Compensation Partners, the Compensation Committee's independent compensation consultant, the Compensation Committee periodically reviews our Independent Director compensation program to ensure continued alignment with comparable companies and sound governance practices. The Committee last reviewed director compensation in 2025 and did not recommend that the Board approve any changes to the Independent Director compensation program.

Under our independent Director compensation program, our Directors receive a cash retainer and an annual equity award as well as additional cash fees for service as Board Chair or Committee Chair. Directors may elect to receive any or all of their cash fees in equity rather than cash, if they prefer. Compensation paid to our Independent Directors for services in 2025 is further described below. Mr. Osanloo, our former President and CEO and former Director, received no separate compensation for his services as Director in 2025. Compensation information for Mr. Osanloo is included in the Executive Compensation section. Mr. Miles served as Interim President and CEO, and his compensation for 2025 is also shown in the Executive Compensation section.

| **Proposal**<br>**2** | &nbsp;&nbsp;**Advisory Vote on** <br>**Executive Compensation** |

---

We are including an advisory vote on the compensation paid to our Named Executive Officers ("NEOs"), as required under Section 14A of the Exchange Act, specifically the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 ("Dodd-Frank Act"), and related SEC rules. An advisory vote is not binding on the Company, but our Compensation Committee and Board intend to take the results of the advisory vote into consideration when making NEO compensation decisions. This proposal is frequently referred to as "Say on Pay" and allows shareholders to express their overall opinion on executive pay. The vote does not speak specifically to any particular element of compensation or any particular NEO. Instead, it is an opportunity to express approval or disapproval on the Company's overall compensation philosophy, practices and procedures. We expect to conduct a Say on Pay vote annually, with the next advisory vote occurring at our 2027 Annual Meeting of Shareholders.

We believe that our compensation philosophy and practices do an excellent job of tying our NEOs' compensation to our strategic objectives and that they are linked to the creation of sustainable value for shareholders. The following sections explain in greater detail our philosophy, the elements of compensation, the targets assigned and how those elements and targets work together to achieve critical objectives.

Our Compensation Committee will consider the results of this proposal when reviewing our compensation philosophy and determining compensation structure going forward and intends to, along with other members of the Board, continue to engage with our shareholders to understand and address any concerns as they arise.

Accordingly, we ask our shareholders to vote "FOR" the following resolution:

RESOLVED, that the Company's shareholders approve, on an advisory basis, the compensation of the named executive officers, as disclosed in the proxy statement for the Company's 2026 annual meeting of shareholders, pursuant to the compensation disclosure rules of the Securities and Exchange Commission.

**Voting Requirement**

The approval, on an advisory basis, of our NEO compensation requires an affirmative vote of a majority of the shareholders present in person or represented by proxy at the Annual Meeting and entitled to vote on Proposal 2. Abstentions shall be counted as a vote against the proposal and broker non-votes shall have no effect.

The result of this proposal is non-binding, but shall be considered by the Compensation Committee and the Board when making future compensation decisions.

**Recommendation of the Board of Directors**

Proposal 2 Advisory Vote on Executive Compensation

**Compensation Philosophy**

The Company's executive compensation philosophy is designed to drive sustained performance, align with long-term shareholder value creation, and support the retention of key leadership talent.

Our Compensation Committee structures total compensation so that a significant majority of executive pay is variable and contingent upon the achievement of pre-established, objective performance goals. This approach reinforces a strong pay-for-performance orientation and aligns executive outcomes with Company performance over both the short and long term.

We maintain a disciplined framework that balances market competitiveness, performance-based differentiation, and effective governance practices, consistent with shareholder expectations.

Our executive compensation policies and practices include:

**• Pay-for-Performance** Our compensation program is designed to ensure a strong correlation between pay and performance. A substantial portion of executive compensation is at risk and tied to quantifiable financial and strategic metrics, with payout opportunities aligned to the level of achievement against these goals. This structure supports clear line-of-sight between performance outcomes and realized compensation.

**• Alignment with Shareholder Interests** Executive compensation is directly linked to Company performance, with incentive outcomes tied to financial results, strategic priorities, and individual contributions. Our long-term incentive program emphasizes multi-year vesting and sustained financial performance, reinforcing alignment with long-term shareholder value creation and discouraging short-term decision-making.

**• Independent Oversight and Governance** The Compensation Committee, composed entirely of independent directors, oversees the design and administration of the executive compensation program. The Committee exercises independent judgment, supported by external advisors, to ensure that compensation outcomes are aligned with performance, competitive market practices, and shareholder interests.

**• Attracting, Retaining and Engaging Top Talent** We provide competitive total compensation opportunities that are differentiated based on performance and criticality of role. Our programs are designed to attract and retain leaders capable of driving the Company's growth and delivering consistent results.

**• Broad-Based Benefits** Our executive benefits program is aligned with those offered to other management Team Members, including health, retirement, stock purchase, paid time off, life insurance, and disability benefits. This approach reinforces a consistent and equitable total rewards philosophy across the organization.

**• Risk Mitigation and Responsible Pay Practices:** Our compensation programs are designed to discourage excessive risk- taking and promote long-term decision-making. Key features include: caps on incentive payouts, multi-year vesting requirements, clawback provisions as described under Clawback Policies, and balanced performance metrics. These elements support a prudent risk profile and are consistent with governance practices.

**• Stock Ownership, Anti-Pledging and Anti-Hedging Policies** We maintain robust stock ownership guidelines applicable to Executive Officers and Board members to reinforce alignment with shareholders. The Company prohibits hedging, pledging, and holding Company securities in margin accounts, ensuring that leadership maintains meaningful and direct exposure to changes in stock price consistent with shareholder alignment best practices.

Proposal 2 Advisory Vote on Executive Compensation

**Compensation Process**

The Compensation Committee maintains a disciplined and rigorous approach to overseeing executive compensation and making compensation decisions throughout the year. The Committee annually evaluates the design and competitiveness of the Company's executive compensation program, considering individual performance, Company growth, profitability, and overall business results. In support of this review, the Committee engages an independent compensation consultant and considers market data from a defined peer group of comparable companies.

In 2025, the Committee continued to retain Meridian Compensation Partners, LLC ("Meridian") as its independent compensation consultant. In making compensation decisions, the Compensation Committee considers the scope of each NEO's responsibilities and their effectiveness in advancing the Company's short- and long-term strategic objectives. The Committee establishes base salary, annual incentives, long-term incentives, and total compensation opportunities at levels designed to attract, motivate, and retain high-performing executive talent in a competitive market.

In Fiscal Year 2025, the Compensation Committee conducted a comprehensive evaluation of each component of compensation and overall total direct compensation for the Company's NEOs. This review incorporated individual performance, Company performance, and market data, including publicly-available information, private survey data, and peer group practices, to assess competitiveness and evolving market trends, with particular focus on long-term incentive design. The Committee reviewed target total direct compensation for 2025, informed by data provided by its independent compensation consultant, Meridian, to ensure the Company's compensation practices are aligned with its competitive market.

The following timeline of key events reflects the Committee's process for executive compensation in 2025.

Proposal 2 Advisory Vote on Executive Compensation

**2025 Advisory Vote on Executive Compensation**

Our Compensation Committee carefully considered the results of the 2025 advisory vote on executive compensation in evaluating our compensation program. At our 2025 Annual Meeting of Shareholders (the "2025 Annual Meeting"), our shareholders approved, on an advisory basis, the compensation of our NEOs as disclosed in our 2025 proxy statement. The proposal was supported by approximately 69% of the total votes cast, which is consistent with our commitment to shareholder engagement and strong governance. We continue to actively engage with shareholders to understand their perspectives and incorporate feedback, where appropriate, into our compensation practices.

**Elements of Compensation**

Our compensation program is designed to emphasize performance-based pay, with a significant portion of total compensation tied to Company performance and long-term value creation.

Proposal 2 Advisory Vote on Executive Compensation

**2025 NEO Compensation**

Our 2025 pay mix was intended to strike a thoughtful balance between pay-for-performance and the achievement of strategic Company objectives and the retention of key executive employees whose leadership we believe is critical to the Company's continued success. A majority of overall executive compensation is at-risk or performance-based pay, over 70%, with a significant percentage of executive compensation delivered through long-term incentive awards, which are designed to closely align leadership's interests with those of our shareholders. By tying a significant portion of compensation to long-term Company performance, we aim to drive accountability, support strategic goals, and reward results that benefit shareholders over the long run.

Proposal 2 Advisory Vote on Executive Compensation

**Base Salary**

**Role in Compensation Program**

Base salary is designed to provide a market-competitive level of fixed compensation to attract and retain key executive talent, while representing a relatively small portion of total direct compensation. This structure reinforces our philosophy of emphasizing performance-based and at-risk pay.

**Governance and Determination Process**

The CEO provides recommendations to the Compensation Committee regarding the base salaries of Executive Officers (other than himself), informed by analysis from the Company's independent compensation consultant.

The Compensation Committee, composed entirely of independent Directors, reviews and approves all executive base salaries, including the CEO's compensation. Salary adjustments are typically considered annually during the first quarter.

**2025 Base Salary Decisions**

Following a comprehensive review of Company performance and market data, the Compensation Committee did not approve base salary increases for any of the Named Executive Officers in 2025.

This decision reflects the Committee's continued focus on:

**•** Maintaining a disciplined pay-for-performance structure, and

**•** Ensuring that a significant majority of executive compensation remains performance-based and at risk.

**At-Risk Pay**

**Role in Compensation Program**

Our at-risk compensation is designed to directly link executive pay to Company performance. Through our short-term incentive program, executives earn performance-based cash awards based on the achievement of pre-established financial and operational objectives.

This structure:

**•** Reinforces accountability for annual performance outcomes

**•** Aligns executive incentives with Company operating performance and strategic priorities

**•** Supports shareholder value creation through a focus on sales growth, operational efficiency, and profitability

**2025 Short-Term Incentive Program (STIP)**

**Pay-for-Performance**

The STIP is designed to ensure a strong relationship between pay and performance, with payouts determined based on achievement against pre-established performance metrics and individual objectives.

Proposal 2 Advisory Vote on Executive Compensation

Target bonus opportunities are expressed as a percentage of base salary and vary by role, reflecting:

**•** Scope of responsibilities and ability to influence results

**•** Market benchmarks and competitive positioning

**•** Individual performance and experience

The Compensation Committee reviews and approves target bonus levels annually, considering:

**•** Market data and peer benchmarks

**•** Proportion of at-risk compensation within total pay

**•** Executive's ability to impact short-term financial and strategic outcomes

The Committee exercises independent judgment, informed by its compensation consultant and management input, in establishing appropriate incentive opportunities.

**Aligned with Shareholder Interests**

In 2025, the short-term incentive program placed greater emphasis on Company financial performance (75%), which was weighted more heavily than individual performance (25%).

This weighting reinforces:

**•** A strong connection between executive pay and Company financial results

**•** Alignment with shareholder interests

**•** Accountability for delivering annual business performance

![04 PRO014041_aligned with.jpg](ptlo-20260417_g129.jpg)

**Linked to Strategic Objectives**

Consistent with prior years, the Compensation Committee established pre-defined annual incentive performance targets for the 2025 Annual Incentive Plan in the first quarter of 2025, including an Adjusted EBITDA target.

Individual performance is assessed based on pre-established objectives aligned with the Company's strategic priorities.

The Compensation Committee reviews and approves the CEO's performance objectives, while the CEO establishes performance objectives for the other Executive Officers, which are reviewed by the Compensation Committee as part of its oversight of the overall incentive program.

The following table reflects the 2025 Short -Term Incentive Program NEO target award opportunities.

Individual performance payouts were calculated based on the individual NEO's performance. Despite disciplined cost management, talent development, and process optimization, the Company missed key financial targets and new restaurant openings, highlighting the need for sharper execution and stronger traffic-driving strategies to achieve our full potential. In making its assessment, the Compensation Committee determined that no individual performance incentive awards were earned by the NEOs.

Consistent with our pay-for-performance philosophy, no short-term incentive awards were earned by executive officers for the year due to performance results below established threshold levels.

| **4** | &nbsp;&nbsp;**Executive Retention Plan** |

---

**Purpose and Rationale**

In fiscal 2025, Portillo's Board of Directors and Compensation Committee, following a review of the current situation and broader market context, approved a one-time Executive Leadership Retention Plan ("Retention Plan") to ensure the stability and continuity of the Portillo's executive leadership team during a period of CEO transition and organizational change, including an Interim CEO and a CEO search process.

In making this determination, the Committee considered: (i) the external market conditions including competitive demand; (ii) the criticality of maintaining continuity during the transition period; and (iii) the institutional knowledge held by the executive leadership team as the Company managed the CEO transition process.

Proposal 2 Advisory Vote on Executive Compensation

**Plan Design and Award Structure**

The Retention Plan was designed to balance the objectives of retention, performance, and shareholder alignment.

One-time awards are meant to be used sparingly and strategically; the Committee selected the following one-time award structure, a mix of cash and equity awards, based on guidance from its independent advisor and a review of current market practice.

**•** Cash Component (50% of base salary): Payable in two installments, in March and October 2026

**•** Equity Component (50% of base salary): Granted as Restricted Stock Units ("RSUs"), cliff vesting 12 months after grant

The awards are subject to the participant's continued employment and the terms of the Company's Senior Executive Severance Plan and Incentive-Based Compensation Recovery Policy.

The Compensation Committee recognizes that retention awards are subject to heightened scrutiny and, accordingly, approved this program as a limited, one-time action to address the unique circumstances of a CEO transition. In evaluating the Retention Plan, the Committee carefully considered the need to maintain leadership continuity and minimize execution risk during this period, while preserving the Company's pay-for-performance philosophy. The structure of the awards, including continued service requirements and partial delivery in equity, was designed to promote retention over a defined period without creating ongoing compensation obligations or replacing performance-based incentives. The Committee believes the cost of the Retention Plan is justified by the importance of maintaining leadership continuity and minimizing the risk of business disruption during the CEO transition.

**Long-Term Equity Incentive**

Consistent with the Company's pay-for-performance philosophy, the performance-based equity awards granted in connection with the 2021 IPO did not achieve established targets and were forfeited in October 2025.

In Fiscal Year 2025, the Company continued its long-term incentive program for NEOs other than the CEO that includes grants of both Restricted Stock Units ("RSUs") and Performance Stock Units ("PSUs") to align executive compensation with long-term shareholder value creation. This equity-based program reflects the Compensation Committee's commitment to a pay-for-performance philosophy and the attraction and retention of key leadership talent. RSUs vest over time to support retention and reinforce long-term commitment, while PSUs are earned based on the achievement of clearly defined performance goals tied to the Company's strategic priorities, such as Revenue and Adjusted EBITDA growth. This program aligns executives' interests with those of our shareholders and promotes a culture of sustained high performance and accountability.

**3-Year Performance-Based Awards (50%)**

Fifty percent (50%) of the overall 2025 long-term equity-based awards were issued to the NEOs as PSUs and are subject to the achievement of performance metrics (Revenue and Adjusted EBITDA growth) over a 3-year forward looking period from

2025 to 2027. Payout amounts between threshold and target, or target and high levels, will be determined using linear interpolation. No value is paid for metrics with outcomes below the threshold achievement levels. Vesting and results will be determined following the performance period, and will settle in shares of common stock on a one-for-one basis.

The number of shares that can be earned under the PSU awards based on the two metrics is determined by multiplying the target number of shares subject to the award by the payout percentage and the weightings, as set forth in the table below:

---

| | | | | |
|:---|:---|:---|:---|:---|
| **3-Year Cumulative Total<br>Revenue Growth Performance<br>Growth Metric (weight: 50%)** | **3-Year Cumulative Total<br>Revenue Growth Performance<br>Growth Metric (weight: 50%)** | **3-Year Cumulative Adjusted EBITDA<br>Growth Performance<br>Growth Goal (weight: 50%)** | **3-Year Cumulative Adjusted EBITDA<br>Growth Performance<br>Growth Goal (weight: 50%)** | **Total Potential Payout** |
| **3-Year Cumulative<br>Revenue Dollars** | **Shares Earned as% of Target PSUs** | **3-Year Cumulative<br>Adjusted EBITDA Growth** | **Shares Earned as %<br>of Target PSUs** | **Shares Earned as %**<br>**of Target PSUs** |
| Below $245M  | —% | Below $25.0M | —% | —% |
| $245M  | 50% | $25.0M | 50% | 50% |
| $345M  | 100% | $45.0M  | 100% | 100% |
| $395M or more  | 200% | $60.0M or more  | 200% | 200% |

---

<sup>(1)</sup> If the cumulative revenue growth dollars and/or the cumulative adjusted EBITDA growth dollars fall between two stated performance levels in the performance goal table, the payout percentage will be determined using linear interpolation. Vesting and payout of each PSU is subject to the Executive Officer's continued employment through the vesting date (except in the event of termination of employment due to death or disability), and each PSU may be paid out on an accelerated basis in the event of a change in control transaction.

**3- and 4-Year Time-Based Awards (50%)**

The remaining 50% of the overall 2025 long-term equity-based awards were issued as Non-Qualified Stock Options ("NQSOs") to the former Chief Executive Officer and RSUs to all other NEOs. The NQSOs vest on the fourth anniversary of the award and are exercisable within a 10-year period from the date of grant, subject to the executive's continued employment. RSUs vest ratably on each of the first three anniversaries of the date of grant, subject to the executive's continued employment, and will settle in shares of common stock on a one-for-one basis. This balanced mix of equity vehicles is designed to drive sustained performance, incentivize the CEO to deliver long-term results, and retain top leadership during a critical phase of growth.

The table below reflects the target-level values of the 2025 long-term equity-based awards.

|:---|:---|:---|:---|

**Former CEO Equity**

In connection with the Company's long-term incentive program in 2025, the former Chief Executive Officer was granted an equity award consisting of 50% NQSOs and 50% PSUs. The NQSOs are subject to a four-year cliff vesting schedule, reinforcing long-term value creation. This balanced mix of equity vehicles is designed to drive sustained performance, incentivize the CEO to deliver long-term results, and retain top leadership during a critical phase of growth. The Compensation Committee believes this structure provides a strong link between pay and performance, while promoting accountability and shareholder value creation.

The table below reflects the former CEO's 2025 long-term equity-based award target-level values approved by the Compensation Committee. These awards were forfeited in their entirety due to termination.

<sup>(2)</sup> Mr. Osanloo ceased to be an Executive Officer of the Company as of September 21, 2025, and awards granted in 2025 were forfeited.

**Timing of Equity Grants**

All equity grants made to Executive Officers must be approved by the Compensation Committee. The Company does not time nor does it plan to time the release of material, non-public information for the purpose of affecting the value of employee or Board compensation. During Fiscal Year 2025, the Company did not grant stock options (or similar awards) to any NEO during any period beginning four (4) business days before and ending one (1) day after the filing of any Company periodic report on Form 10-Q or Form 10-K, or the filing or furnishing of any Company Form 8-K that disclosed any material non-public information.

**Executive Employment Arrangements**

The Company does not routinely enter into employment agreements with its Executive Officers; however, the Company has certain legacy agreements from our pre-IPO period with Mr. Osanloo. The following is a summary of the material terms of the employment arrangements that we have with Mr. Miles, Mr. Patterson, Ms. Hook, Mr. Darden, Ms. Waite, Ms. Kaiser, and Mr. Osanloo. Mr. Patterson commenced employment with the Company on February 23, 2026 at a base salary of $800,000. Additional details regarding Mr. Patterson's full compensation structure are set forth below.

**Michael A. Miles, Jr.**

The Company entered into a letter agreement on October 6, 2025, which provided for an initial term of three months (the "Initial Term"), during which time Mr. Miles was paid a base salary at an annualized rate of $60,000, and was granted a restricted stock unit ("RSU") award with a grant date fair value of $1,200,000 (the "Initial Term RSUs"), which will fully vest on the one-year anniversary of the grant date. For his service as Interim CEO following the conclusion of the Initial Term, Mr. Miles was paid a base salary at an annualized rate of $60,000 and was granted an RSU award with a grant date fair value of $400,000 each month, which will fully vest on the one-year anniversary of the applicable grant date. In connection with Mr. Miles' letter agreement, dated October 6, 2025, in the event that Mr. Miles' service as Interim CEO and a member of the Board terminates: (i) prior to the conclusion of the Initial Term, the Initial Term RSUs will vest on a prorated basis, and (ii) following the conclusion of the Initial Term, his outstanding RSUs will fully vest. Because Mr. Miles concluded his service as Interim CEO and continued to serve on the Board as a Director, the RSUs in connection with his service as Interim CEO will continue to vest until their vesting date; however, the RSUs granted in connection with his service as a Director will vest on a pro-rated basis at the conclusion of his service on the Board following the 2026 Annual Meeting. The Compensation Committee reviewed market practice in setting the former Interim CEO's compensation.

**Michael Osanloo**

The Company entered into an employment agreement with Michael Osanloo (the "Osanloo Employment Agreement") on August 3, 2018. The Osanloo Employment Agreement provided for a 3-year initial term and renewed annually. The Osanloo Employment Agreement originally provided for a base salary of $750,000 and annual incentive cash compensation with an annual target equal to 100% of base salary, up to a maximum of 150% (subsequently increased to 200%) of base salary, a signing bonus of $200,000 which was paid within 30 days of Mr. Osanloo's start date and an award of 15,000,000 options granted under the 2014 Plan, split equally between options that are subject solely to time-vesting, and options that are subject to time-vesting and performance-vesting (which was later adjusted based on the Company's pre-IPO reverse stock split). Mr. Osanloo was also provided the opportunity to invest up to $1,500,000 for the purchase of LLC Units of the Company, at the then fair market value. In connection with Mr. Osanloo's Separation Agreement and Release Agreement, dated September 29, 2025 (the "Separation Agreement"), Mr. Osanloo was entitled to receive the following payments and benefits consistent with the Company's Senior Executive Severance Plan: (i) 18 months of base salary continuation equal to approximately $1.5 million in cash; (ii) a prorated bonus for 2025, based on actual performance which paid out at zero; (iii) continued medical, dental and vision coverage at active employee rates for up to 18 months; and (iv) outplacement services for up to 12 months, with a value not to exceed $25,000. In addition, Mr. Osanloo's outstanding stock option awards granted to him on October 1, 2018 will remain exercisable until the 10th anniversary of the grant date. Mr. Osanloo's receipt of such payments and benefits is subject to his continued compliance with the restrictive covenants set forth in the Company's Senior Executive Severance Plan, any other pre-existing restrictive covenants in effect as of the date of the Separation Agreement, a two-year non-competition covenant set forth in the Separation Agreement, and his performance of such knowledge transfer and strategic consulting services as the Company may have reasonably requested from time to time during a consulting period commencing on the Transition Date and ending on December 20, 2025.

**Other Benefits**

**Personal Financial Management**

Certain management Team Members of the Company have access to Ayco Personal Financial Management to provide certain investment advice and services as well as tax return preparation. In Fiscal Year 2025, Ms. Hook, Ms. Waite and Mr. Osanloo took advantage of the personal financial management perquisite.

**Employee Stock Purchase Plan**

The Company maintains the Employee Stock Purchase Plan (the "ESPP"), adopted in June 2022, to provide Team Members, including our NEOs, with an opportunity to purchase shares of the Company's common stock through payroll deductions at not less than 85% of the market price on the purchase date, subject to Company discretion.

The ESPP is a non-qualified plan under Section 423 of the Internal Revenue Code. The Compensation Committee believes the ESPP is an attractive benefit that assists the Company in retaining key Team Members, securing new qualified Team Members and providing incentives for Team Members to work towards achieving the Company's key objectives because it gives Team Members access to the Company's equity at a discounted price. In Fiscal Year 2025, Ms. Hook, Ms. Waite, Ms. Kaiser and Mr. Osanloo participated in the ESPP.

**401(k) Plan**

Our NEOs participate in the same 401(k) retirement plan as the rest of our Team Members.

**Other Benefits and Perquisites**

Our NEOs participate in the same medical benefit plans generally available to our management Team Members. These benefit plans include health insurance, dental and vision coverage, life insurance and disability coverage. The NEOs receive the same coverage as the rest of our management Team Members, as well as full coverage of the premium-equivalent. The NEOs also may elect to participate in our medical and dependent care flexible spending plan, on the same terms and conditions as other Team Members.

In addition, we make available to our Team Members, including our NEOs, the ability to dine at our restaurants a limited number of times each year for free or at a discount.

**Additional Compensation Practices**

**Share Ownership Guidelines**

The Compensation Committee has instituted share ownership guidelines to foster alignment between the interests of our Executive Officers, members of management, and shareholders, promoting behaviors that positively impact share price appreciation and total shareholder return. These guidelines stipulate that our NEOs are expected to retain a specified number of shares, valued at multiples of their annual salary based on their respective positions, for the duration of the officer's tenure.

The Company adopted the following share ownership guidelines in April 2022 for its Directors and members of management:

---

| | |
|:---|:---|
| **Position** | **Ownership Requirement** |
| Chief Executive Officer | 5x annual base salary |
| Other C-Suite Officers | 3x annual base salary |
| Senior Vice Presidents | 2x annual base salary |
| Non-employee Directors | 4x annual cash Board retainer |

---

Shares counted toward the ownership requirement include (i) shares owned directly by the individual (including Class B shares and shares held in an individual retirement account or trust if the individual is the beneficiary or trustee); (ii) options and restricted stock units granted under any Company-sponsored plan, whether vested or unvested; and (iii) deferred stock or equivalent stock unit awards under any Company-sponsored plan.

Compliance with the guidelines is assessed multiple times a year using the average closing price for the prior 90 trading days. Each Director and member of management has a five-year grace period to achieve compliance with the guidelines, which period commenced on October 21, 2021 for any officer or Director in role at that time, or on the date of hire or promotion for any member of management or Director who joined subsequently. In the event that a Director or member of management does not satisfy the ownership guidelines, they would be restricted from selling or transferring stock until such time as they satisfy the guidelines. In limited hardship circumstances, an alternative ownership requirement may be temporarily adopted.

As of the end of Fiscal Year 2025, most members of management and Directors had satisfied the ownership requirements or were progressing toward achieving the target ownership requirements within the 5-year time period.

**Hedging & Pledging**

Under our Insider Trading Compliance Policy, our Directors, officers and Team Members are generally not permitted to engage in hedging or similar transactions (including but not limited to prepaid variable forwards, equity swaps, collars and exchange funds). The General Counsel may approve entry into such transactions following a review of the proposed transaction and the justification for it. Additionally, such persons also may not pledge Company securities, including as collateral for a margin loan. For disclosure about our Insider Trading Compliance Policy and a full copy of the policy, available as an exhibit, please see the Company's Form 10-K filed on February 24, 2026.

**Clawback Policies**

In October 2023, the Company adopted an Incentive-Based Compensation Recovery Policy, which allows the Company to recover erroneously awarded compensation from Executive Officers in compliance with the requirements of Listing Rule 5608 of the Nasdaq Stock Market LLC and related SEC regulations. The full copy is available as an exhibit to the Company's 2025 Form 10-K filed on February 24, 2026.

The 2021 Equity Incentive Plan and related agreements also provide for the ability to claw back certain compensation awarded under the Plan.

**Potential Payments Upon Termination**

**Senior Executive Severance Plan**

Portillo's Inc. Senior Executive Severance Plan (the "Senior Executive Severance Plan"), applicable to employees at the level of senior vice president and above, provides for certain payments to our NEOs in connection with their termination from the Company under certain circumstances. With respect to each of the Company's NEOs, the Senior Executive Severance Plan provides severance upon a termination of employment by the Company without cause or a resignation of employment by the employee for good reason, in each case, that occurs upon or within 24 months following a change in control equal to 2.0x (3.0x in the case of the CEO) the sum of the employee's annual base salary and target annual bonus, as well as a pro-rated target annual bonus for the year of termination, the prior year bonus to the extent unpaid, outplacement assistance, and subsidized COBRA during the severance period. Upon a termination of employment by the Company without cause prior to a change in control or following the change in control protection period, each NEO receives 1.0x (1.5x in the case of the CEO, to the extent applicable) the employee's annual base salary, as well as a pro-rated annual bonus for the year of termination based on actual period, the prior year bonus to the extent unpaid, outplacement assistance, and subsidized COBRA during the severance period.

Proposal 2 Advisory Vote on Executive Compensation

**CEO Pay Ratio**

Pursuant to Regulation S-K and the Dodd-Frank Act, we disclose the following information about the relationship between the total annual compensation of our median Team Member and the total annual compensation of our Interim President and Chief Executive Officer, Michael A. Miles, Jr. We believe that this calculation is compliant with Item 402(u) of Regulation S-K.

We identified the median Team Member by examining the total earnings for the 2025 Fiscal Year for all Team Members employed by us on October 1, 2025, excluding the CEO, whether employed on a full-time, part-time, seasonal or temporary basis, with the following methodology and assumptions:

**•** As of October 1, 2025, our Team Members consisted of 7,865 individuals, 100% of whom were located in the United States.

**•** With respect to Team Members who were employed less than a full year, we assumed in the calculation that they had worked the full 12-month period.

**•** Of all possible median Team Members, we selected a Team Member who did not have atypical elements (such as disability pay or special earnings while on leave).

We calculated the total annual compensation for our median Team Member using the same methodology used with our NEOs as set forth in the Summary Compensation Table. The total annual compensation for our median Team Member for 2025 was $19,949. As disclosed in the Summary Compensation Table, our CEO's total annual compensation for 2025 was $1,467,689. Based on these calculations, our estimate for the ratio of total annual compensation of our CEO to the median of all other Team Members was 74:1.

**Pay Versus Performance**

As required by Item 402(v) of Regulation S-K, we are providing the following information about the relationship between executive compensation actually paid and certain Company financial performance indicators. For further information concerning the Company's pay-for-performance philosophy and how the Company's executive compensation aligns with the Company's performance, refer to "Compensation Discussion & Analysis." The Compensation Committee did not consider the Compensation Actually Paid ("CAP") measure below in making its compensation decisions for any of the years shown below. The non-GAAP reconciliations for adjusted EBITDA are provided in Annex I.

| **Proposal**<br>**3** | &nbsp;&nbsp;**Ratification of the<br>Independent Registered Public<br>Accounting Firm** |

---

Deloitte & Touche LLP has been appointed by the Audit Committee, which is composed entirely of independent Directors, to be our independent registered public accounting firm for the fiscal year ending December 27, 2026. Deloitte & Touche LLP was our independent registered public accounting firm for Fiscal Year 2025. A representative of Deloitte & Touche LLP is expected to be present at the Annual Meeting and to have an opportunity to make a statement if they desire to do so. The Deloitte & Touche LLP representative is also expected to be available to respond to appropriate questions at the meeting.

The Audit Committee has the sole authority to appoint, subject to shareholder ratification, or replace the independent registered public accounting firm, which reports directly to the Audit Committee, and is directly responsible for the compensation and oversight of the independent registered public accounting firm. The Audit Committee considered several factors when deciding whether to re-engage Deloitte & Touche LLP, including the firm's professional qualifications and experience and its performance during the prior year. The Audit Committee determined that appointing Deloitte to serve as the Company's independent registered public accounting firm was in the best interests of the Company and its shareholders and appointed Deloitte and Touche LLP as our independent auditor for the fiscal year ending December 27, 2026.

**Oversight of Independent Registered Public Accounting Firm**

In the Audit Committee's oversight of the independent registered public accounting firm and its determination of whether to reappoint the independent registered public accounting firm, our Audit Committee:

**•** Conducts an annual assessment of the independent registered public accounting firm's performance, qualifications and independence, taking into account the opinions of management and the internal auditor;

**•** Reviews, in advance, all non-audit services provided by the independent registered public accounting firm, specifically with regard to the effect on the firm's independence;

**•** Considers the independent registered public accounting firm's familiarity with our operations, businesses, accounting policies and practices and internal control over financial reporting;

**•** Conducts regular executive sessions with the independent registered public accounting firm;

**•** Conducts private and individual executive sessions with the Chief Executive Officer, Chief Financial Officer, and General Counsel at each in-person Committee meeting;

**•** Reviews candidates for the lead engagement partner in conjunction with the mandated rotation of the public accountant's lead engagement partner;

**•** Reviews recent reports from the Public Company Accounting Oversight Board and other professional or governmental authorities on the independent registered public accounting firm; and

**•** Obtains and reviews a report from the independent registered public accounting firm describing all relationships between the independent registered public accounting firm and our Company annually to assess the independence of the independent registered public accounting firm.

Proposal 3 Ratification of the Independent Registered Public Accounting Firm

**Voting Requirement**

Although shareholder ratification is not required, the Audit Committee and the Board value the opinion of shareholders. The affirmative vote of a majority of the shareholders present in person or represented by proxy at the Annual Meeting and entitled to vote on Proposal 3 shall be deemed to approve of this proposal. Abstentions and broker non-votes will be counted as votes "AGAINST" this proposal. If the shareholders do not ratify the appointment, the Audit Committee may reconsider the appointment of Deloitte, for 2026 or in future years. Even if shareholders do ratify the appointment, it is possible that the Audit Committee may change the appointed independent registered public accounting firm if the Committee determines that that is in the best interests of the Company and its shareholders.

| All other fees<sup>(3)</sup> | 2 | 2 |
| **Total** | $2174 | $2377 |

---

<sup>(1)</sup> These are fees and expenses for professional services performed by Deloitte Entities for the audit of our annual financial statements and review of financial statements included in our Form 10-Q filings, as well as services that are normally provided in connection with statutory and regulatory filings or engagements.

<sup>(2)</sup> These are fees for professional services performed by Deloitte Entities with respect to tax compliance, tax advice and tax planning. Fees incurred principally relate to review of tax returns, preparation of tax returns or supporting documentation and consultation with regard to various tax planning issues.

<sup>(3)</sup> These are fees related to accounting research database subscription services.

All such services and fees provided by our independent registered public accounting firm during Fiscal Year 2025 and Fiscal Year 2024 were pre-approved by the Audit Committee.

**Policy on Pre-Approval of Audit and Permissible Non-Audit Services of Independent Registered Public Accounting Firm**

The Audit Committee's charter provides that the Audit Committee, or the Chair of the Audit Committee, must pre-approve any audit or non-audit service provided to us by Deloitte, unless the engagement is entered into pursuant to appropriate

pre-approval policies established by the Audit Committee or if the service falls within available exceptions under SEC rules. Without limiting the foregoing, the Audit Committee may delegate authority to one or more independent members of the Audit Committee to grant pre-approvals of audit and permitted non-audit services, and any such pre-approvals must be presented to the full Audit Committee at its next scheduled meeting. All such services and fees provided by our independent registered public accounting firm during Fiscal Year 2025 and Fiscal Year 2024 were pre-approved by the Audit Committee.

Proposal 3 Ratification of the Independent Registered Public Accounting Firm

**Audit Committee Report**

The Audit Committee is governed by a written charter, which may be found in the "Governance" section of Portillo's website located at **https://investors.portillos.com/corporate-governance/governance-overview**. The charter was adopted by the Company's Board of Directors and is reviewed annually by the Audit Committee.

The Audit Committee is currently composed of four Directors, all of whom meet the criteria for independence under the applicable NASDAQ and SEC rules and the Sarbanes-Oxley Act. The current members of the Audit Committee are Ms. Bordelon, Mr. Glass, Ms. Dodson and Mr. Hartung. Ms. Bordelon currently serves as the Chairperson of the Committee. The Board evaluated the credentials of Ms. Bordelon, Mr. Glass and Mr. Hartung and designated them as "audit committee financial experts" under applicable SEC rules.

The Audit Committee is responsible for overseeing the quality and integrity of the Company's accounting, auditing, financial reporting and internal control practices, as well as the Company's risk assessment and management practices including, but not limited to, the Company's fraud risk assessment practices, cybersecurity and other information technology risks. The Audit Committee is responsible for, in addition to other activities, the appointment, retention and compensation of the Company's independent registered public accounting firm. The Audit Committee has a written policy with respect to the pre-approval of non-audit services.

Management has the primary responsibility for establishing and maintaining effective internal control over financial reporting and preparing the Company's financial statements and disclosures in accordance with generally accepted accounting principles in the United States (GAAP).

Deloitte & Touche LLP ("Deloitte"), the Company's independent registered public accounting firm, is responsible for expressing opinions on the conformity of the Company's audited financial statements with generally accepted accounting principles and on the effectiveness of the Company's internal control over financial reporting. The Audit Committee (i) reviewed and discussed with management the Company's audited consolidated financial statements as of December 28, 2025 and for the year then ended; (ii) discussed with Deloitte the matters required by Public Company Accounting Oversight Board ("PCAOB") Auditing Standard No. 1301, Communication with Audit Committees, and matters required by applicable requirements of the PCAOB and SEC; (iii) received the written disclosures and the letter from Deloitte required by applicable requirements of the PCAOB regarding Deloitte's communications with the Audit Committee regarding independence and discussed with Deloitte their independence; and (iv) considered whether Deloitte's provision of non-audit services to the Company is compatible with maintaining Deloitte's independence.

The Audit Committee met seven times during Fiscal Year 2025, which included the Committee's review of the Company's quarterly earnings releases and related SEC filings, when appropriate. The Audit Committee also met in separate executive sessions with Deloitte, the Chief Financial Officer and other members of management as needed.

Based on the review and discussions described above, the Audit Committee recommended to the Company's Board of Directors that the audited consolidated financial statements for the fiscal year ended December 28, 2025 be included in the Annual Report on Form 10-K.

**Audit Committee:**

Ann Bordelon, Chairperson

Noah Glass

Paulette Dodson

Jack Hartung

*The Report of the Audit Committee does not constitute soliciting material and should not be deemed filed or incorporated by reference into any filing under the Securities Act of 1933 or the Securities Exchange Act of 1934, except to the extent we specifically incorporate this report by reference.*

**•** Each of the Directors and Named Executive Officers individually; and

**•** All Directors and officers as a group.

The following table assumes that certain pre-IPO LLC members (the "pre-IPO LLC Members") redeem or exchange all of their LLC Units and shares of Class B common stock for newly issued shares of our Class A common stock on a one-for-one basis. In accordance with the rules of the SEC, beneficial ownership includes voting or investment power with respect to securities and includes the shares issuable pursuant to stock options that are exercisable within 60 days of April 10, 2026. In computing the number of shares of our Class A common stock beneficially owned by a person and the percentage ownership, we deemed outstanding shares of our Class A common stock subject to options held by that person that are currently exercisable or exercisable within 60 days of April 10, 2026. We did not deem these shares of our Class A common stock outstanding, however, for the purpose of computing the percentage ownership of any other person. Unless otherwise indicated, the address for each listed shareholder is: c/o Portillo's Inc., 2001 Spring Road, Suite 400, Oak Brook, Illinois 60523. To our knowledge, except as indicated in the footnotes to this table and pursuant to applicable community property laws, the persons named in the table have sole voting and investment power with respect to all shares of common stock.

**Delinquent Section 16(a) Reports**

Delinquent Section 16(a) Reports Under U.S. securities laws, directors, certain officers and persons holding more than 10% of our Class A common stock must report their initial ownership of our common stock and any changes in their ownership to the SEC. The SEC has designated specific due dates for these reports and we must identify in this Proxy Statement those persons who did not file these reports when due during the last fiscal year. Based solely on our review of copies of the reports filed with the SEC and the written representations of our Directors and executive officers, we believe that all reporting requirements for fiscal 2025 were complied with by each person who at any time during Fiscal Year 2023 was a Director or an officer or held more than 10% of our common stock, except that Jack Hartung filed one Form 3 late in connection with his joining the Board.

**Certain Relationships and Related Party Transactions**

**Related Party Transaction Policy**

We have a written Related Person Transaction Policy (the "Policy"), which sets forth our policy with respect to the review, approval, ratification and disclosure of all related person transactions by our Audit Committee. In accordance with the Policy, our Audit Committee has overall responsibility for implementation of and compliance with the Policy.

For purposes of the Policy, a "related person transaction" is a transaction, arrangement or relationship (or any series of similar transactions, arrangements or relationships) in which we were, are or will be a participant and the amount involved exceeded, exceeds or will exceed $120,000 and in which any related person (as defined in the Policy) had, has or will have a direct or indirect material interest. A "related person transaction" does not include any employment relationship or transaction involving an executive officer and any related compensation resulting solely from that employment relationship that has been reviewed and approved by our Board or our Compensation Committee, as applicable. A "related person" includes (i) our Directors, Director Nominees or Executive Officers, (ii) any 5% beneficial owner of our voting securities, or (iii) any immediate family member of the foregoing.

The Policy requires that notice of a proposed related person transaction be provided to our General Counsel prior to entry into such transaction. If our General Counsel determines that such transaction is a related person transaction, the proposed transaction will be submitted to our Audit Committee for consideration at its next meeting. Under the Policy, our Audit Committee may approve only those related person transactions that are in, or are not inconsistent with, the Company's best interests. In reviewing and approving any related party transaction, the Audit Committee is tasked to consider all of the relevant facts and circumstances, as well as various factors enumerated in the Policy.

The Policy also provides that the Audit Committee review certain previously approved or ratified related person transactions that are ongoing to determine whether the related person transaction remains in our best interests and the best interests of our shareholders. Additionally, we will make periodic inquiries of Directors and officers with respect to any potential related person transaction to which they may be a party or of which they may be aware.

**Related Party Transactions**

We describe below any transactions and series of similar transactions during our last fiscal year or currently proposed, to which we were a party or will be a party, in which:

**•** the amounts involved exceeded or will exceed $120,000; and

**•** any of our Directors, Executive Officers or beneficial holders of more than 5% of any class of our capital stock had, have, or will have a direct or indirect material interest.

Other than as described below, there have not been, nor are there any currently proposed, transactions or series of similar transactions meeting this criteria to which we have been or will be a party other than compensation arrangements.

**Registration Rights Agreement & Redemption of LLC Units**

In connection with the IPO, we entered into a registration rights agreement with Berkshire and certain of our other shareholders. This agreement will provide Berkshire and their permitted transferees with "demand" registrations, which will require us to register shares of our common stock under the Securities Act of 1933 (the "Securities Act"). Each of our shareholders that is a party to the registration rights agreement will also be entitled to customary "piggyback" registration rights and entitled to participate on a pro rata basis in any registration of our common stock under the Securities Act that we may undertake. The registration rights agreement will also require us to maintain an effective shelf registration statement with respect to shares registered pursuant to the registration rights agreement, require that we will pay certain expenses relating to such registrations and require that we indemnify the shareholders party to the registration rights agreement against certain liabilities which may arise under the Securities Act.

In the second quarter of 2025, certain pre-IPO LLC Members affiliated with Berkshire Partners LLC redeemed 7,290,465 LLC units in the aggregate 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.

**Amended Portillo's OpCo Agreement**

In connection with the IPO transactions, Portillo's Inc., Portillo's OpCo and each of the pre-IPO LLC Members entered into the Amended LLC Agreement. Following the IPO transactions, and in accordance with the terms of the Amended LLC Agreement, we operate our business through Portillo's OpCo. Pursuant to the terms of the Amended LLC Agreement, so long as the Continuing Pre-IPO LLC Members continue to own any LLC Units or securities redeemable or exchangeable into shares of our Class A common stock, we will not, without the prior written consent of such holders, engage in any business activity other than the management and ownership of Portillo's OpCo or own any assets other than securities of Portillo's OpCo and/or any cash or other property or assets distributed by or otherwise received from Portillo's OpCo, unless we determine in good faith that such actions or ownership are in the best interests of Portillo's OpCo.

As the sole managing member of Portillo's OpCo, we have control over all of the affairs and decision making of Portillo's OpCo. As such, through our officers and Directors, we are responsible for all operational and administrative decisions of Portillo's OpCo and the day-to-day management of Portillo's OpCo's business. We will fund any dividends to our shareholders by causing Portillo's OpCo to make distributions to the holders of LLC Units and us, subject to the limitations imposed by our debt agreements.

The holders of LLC Units will generally incur U.S. federal, state and local income taxes on their proportionate share of any taxable income of Portillo's OpCo. The Amended LLC Agreement provides for pro rata cash distributions to the holders of LLC Units for purposes of funding their tax obligations in respect of the taxable income of Portillo's OpCo that is allocated to them. Generally, these tax distributions will be computed based on our estimate of the net taxable income of Portillo's OpCo allocated to the holder of LLC Units that receives the greatest proportionate allocation of income multiplied by an assumed tax rate equal to the highest effective marginal combined U.S. federal, state and local income tax rate prescribed for an individual or corporation residing in New York, New York, whichever is higher. As a result of (i) potential differences in the amount of taxable income allocable to us and the other LLC Unit holders, (ii) the lower tax rate applicable to corporations than individuals and (iii) the use of an assumed tax rate in calculating Portillo's OpCo's distribution obligations, we may receive tax distributions significantly in excess of our tax liabilities and obligations to make payments under the Tax Receivable Agreement.

Except as otherwise determined by us, if at any time we issue a share of our Class A common stock, the net proceeds received by us with respect to such share, if any, shall be concurrently invested in Portillo's OpCo and Portillo's OpCo shall issue to us one LLC Unit. Similarly, except as otherwise determined by us, (i) Portillo's OpCo will not issue any additional LLC Units to us unless we issue or sell an equal number of shares of our Class A common stock and (ii) should Portillo's OpCo issue any additional LLC Units to the pre-IPO LLC Members or any other person, we will issue an equal number of shares of our Class B common stock to such pre-IPO LLC Members or any other person. Conversely, if at any time any shares of our Class A common stock are redeemed, purchased or otherwise acquired by us, Portillo's OpCo will redeem, purchase or otherwise acquire an equal number of LLC Units held by us, upon the same terms and for the same price per security, as the shares of our Class A common stock are redeemed, purchased or otherwise acquired. In addition, Portillo's OpCo will not effect any subdivision (by any unit split, unit distribution, reclassification, reorganization, recapitalization or otherwise) or combination (by reverse unit split, reclassification, reorganization, recapitalization or otherwise) of the LLC Units unless it is accompanied by a substantively identical subdivision or combination, as applicable, of each class of our common stock, and we will not effect any subdivision or combination of any class of our common stock unless it is accompanied by a substantively identical subdivision or combination, as applicable, of the LLC Units.

Under the Amended LLC Agreement, the holders of LLC Units (other than us) have the right to require Portillo's OpCo to redeem all or a portion of their LLC Units for newly-issued shares of Class A common stock on a one-for-one basis in accordance with the terms of the Amended LLC Agreement. Upon the exercise of the redemption right, the redeeming member will surrender its LLC Units to Portillo's OpCo for cancellation. The Amended LLC Agreement requires that we contribute shares of our Class A common stock to Portillo's OpCo in exchange for an amount of newly-issued LLC Units in Portillo's OpCo equal to the number of LLC Units redeemed from the holders of LLC Units. Portillo's OpCo will then distribute the shares of our Class A common stock to such holder of an LLC Unit to complete the redemption. In the event of a redemption request by a holder of an LLC Unit, we may, at our option, effect a direct exchange of Class A common stock for LLC Units in lieu of such a redemption. Whether by redemption or exchange, we are obligated to ensure that at all times the number of LLC Units that we own equals the number of shares of Class A common stock issued by us (subject to certain exceptions for treasury shares and shares underlying certain convertible or exchangeable securities). Shares of Class B common stock will be canceled on a one-for-one basis if we, following a redemption request of a holder of an LLC Unit, redeem or exchange LLC Units of such holder of an LLC Unit pursuant to the terms of the Amended LLC Agreement.

Other Matters

The Amended LLC Agreement provides that, in the event that a tender offer, share exchange offer, issuer bid, take-over bid, recapitalization or similar transaction with respect to our Class A common stock is proposed by us or our shareholders and approved by our Board or is otherwise consented to or approved by our Board, the holders of LLC Units will be permitted to participate in such offer by delivery of a notice of redemption or exchange that is effective immediately prior to the consummation of such offer. In the case of any such offer proposed by us, we are obligated to use our reasonable best efforts to enable and permit the holders of LLC Units to participate in such offer to the same extent or on an economically equivalent basis as the holders of shares of our Class A common stock without discrimination. In addition, we are obligated to use our reasonable best efforts to ensure that the holders of LLC Units may participate in each such offer without being required to redeem or exchange LLC Units.

The Amended LLC Agreement provides that, except for transfers to us as provided above or to certain permitted transferees, the LLC Units and corresponding shares of Class B common stock may not be sold, transferred or otherwise disposed of.

Subject to certain exceptions, Portillo's OpCo will indemnify all of its members and their officers and other related parties against all losses or expenses arising from claims or other legal proceedings in which such person (in its capacity as such) may be involved or become subject to in connection with Portillo's OpCo's business or affairs, the Amended LLC Agreement, or any related document.

Portillo's OpCo may be dissolved upon (i) the determination by us to dissolve Portillo's OpCo or (ii) any other event which would cause the dissolution of Portillo's OpCo under the Delaware Limited Liability Company Act, unless Portillo's OpCo is continued in accordance with the Delaware Limited Liability Company Act. Upon dissolution, Portillo's OpCo will be liquidated and the proceeds from any liquidation will be applied and distributed in the following manner: (a) first, to creditors (including creditors who are members or affiliates of members) in satisfaction of all of Portillo's OpCo's liabilities (whether by payment or by making reasonable provision for payment of such liabilities, including the setting up of any reasonably necessary reserves) and (b) second, to the members in proportion to their vested LLC Units.

**Tax Receivable Agreement**

We acquired certain favorable tax attributes and a share of the existing tax basis of the assets of Portillo's OpCo in the IPO. In addition, future redemptions or exchanges by pre-IPO LLC Members of LLC Units for shares of our Class A common stock or cash are expected to result in favorable tax attributes for us. These tax attributes would not be available to us in the absence of those transactions and are expected to reduce the amount of tax that we would otherwise be required to pay in the future.

Upon completion of the IPO, we became party to a Tax Receivable Agreement with certain of our pre-IPO LLC Members ("TRA Parties"). Under the Tax Receivable Agreement, we generally will be required to pay to the TRA Parties, in the aggregate, 85% of the amount of cash savings, if any, in U.S. federal, state and local income tax 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 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 in connection with the 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.

We expect that the payments we will be required to make under the Tax Receivable Agreement will be substantial. Assuming no material changes in relevant tax law and that we earn sufficient taxable income to realize all tax benefits that are subject to the Tax Receivable Agreement, we estimate that the tax savings associated with all tax attributes described above would aggregate to approximately $414.6 million as of December 28, 2025. Under this scenario, we would be required to pay the TRA Parties approximately 85% of such amount, or $352.4 million, primarily over the next 15 years, substantially declining in year 16 through year 47. We paid $7.9 million related to tax year 2024 and $7.7 million relating to tax year 2023 in the quarters ended March 29, 2026 and March 30, 2025, respectively. The actual amounts we will be required to pay may materially differ from these amounts, because potential future tax savings that we will actually realize or be deemed to realize, and the Tax Receivable Agreement payments made by us, will be calculated based in part on the market value of our Class A common stock at the time of each exchange of an LLC Unit for a share of Class A common stock and the prevailing applicable federal tax rate (plus the assumed combined state and local tax rate) applicable to us over the life of the Tax Receivable Agreement and will depend on our generating sufficient taxable income to realize the tax benefits that are subject to the Tax Receivable Agreement. Payments under the Tax Receivable Agreement are not conditioned on our existing owners' continued ownership of us. There may be a material negative effect on our liquidity if, as a result of timing discrepancies or otherwise, the payments under the Tax Receivable Agreement exceed the actual benefits we realize in respect of the tax benefits that are subject to the Tax Receivable Agreement and/or distributions to us by Portillo's OpCo are not sufficient to permit us to make payments under the Tax Receivable Agreement after we have paid taxes.

**Who can vote at the Annual Meeting?**

Only holders of record of our common stock at the close of business on April 10, 2026 (the **"Record Date"**) will be entitled to vote at the Annual Meeting. At the close of business on the Record Date, we had 72,160,015 shares of Class A common stock outstanding and entitled to vote and 3,424,546 shares of Class B common stock outstanding and entitled to vote. Holders of the Company's Class A common stock and Class B common stock are entitled to one vote for each share held as of the Record Date. Shareholders do not have cumulative voting rights.

**What is a quorum and how does it impact the meeting?**

A quorum is required for our shareholders to conduct business at the Annual Meeting. The holders of a majority in voting power of the shares entitled to vote at the Annual Meeting, present or represented by proxy, will constitute a quorum for the transaction of business. Your shares are counted as present at the Annual Meeting if you are present and vote online at the Annual Meeting or if you have properly submitted a proxy. Abstentions and "broker non-votes" (as defined below) will be counted in determining whether there is a quorum.

**What vote is needed to approve each item?**

Proposal No. 1 – Election of Directors, provides that Directors will be elected by a plurality of the votes cast by the holders of shares present in person or represented by proxy at the Annual Meeting and entitled to vote thereon, which means that the eight nominees receiving the highest number of "for" votes will be elected. Withheld votes and broker non-votes will have no effect on Proposal No. 1.

Proposal No. 2 – Advisory Vote on Executive Compensation, is a non-binding vote. Approval requires the affirmative vote of a majority of the shareholders present in person or represented by proxy at the Annual Meeting and entitled to vote on Proposal No. 2. Abstentions shall count as a vote against the proposal. Broker non-votes will have no effect on Proposal No. 2.

Proposal No. 3 – Ratification of Appointment of Independent Registered Public Accounting Firm, requires the affirmative vote of a majority of the shareholders present in person or represented by proxy at the Annual Meeting and entitled to vote on Proposal No. 3. Abstentions will count the same as votes against the proposal. There will be no broker non-votes with respect to Proposal No. 3 because a broker may exercise its discretion to vote for or against the proposal in the absence of instruction from its clients.

Other Matters

**How do I vote my shares?**

If you are a registered holder, meaning that you hold your shares directly (not through a bank, broker or other nominee), you may vote online at the Annual Meeting, by telephone or electronically through the Internet by following the instructions included on your Notice of Internet Availability of Proxy Materials or proxy card, or by completing, dating, signing and promptly returning your proxy card. All signed, returned proxies that are not revoked will be voted in accordance with the instructions contained therein. Signed proxies that give no instructions as to how they should be voted on a particular proposal at the Annual Meeting will be counted as votes "for" such proposal, and, in the case of the election of Directors, as a vote "for" the election of each of the nominees presented by the Board.

If your shares are held through a bank, broker or other nominee, you are considered the beneficial owner of those shares. You may be able to vote by telephone or electronically through the Internet in accordance with the voting instructions provided by that nominee. You may also vote by completing, dating, signing and promptly returning the voting instruction form sent by that nominee. You must obtain a legal proxy from the nominee that holds your shares if you wish to vote online at the Annual Meeting. If you do not provide voting instructions to your broker in advance of the Annual Meeting, Nasdaq rules grant your broker discretionary authority to vote on "routine" proposals. Where a proposal is not "routine," a broker who has received no instructions from its clients does not have discretion to vote its clients' uninstructed shares on that proposal, and the unvoted shares are referred to as "broker non-votes." At the 2026 Annual Meeting, Proposals No. 1 and 2 are not considered "routine" proposals, but Proposal No. 3 is considered a "routine" proposal.

In the event that sufficient votes in favor of the proposals are not received by the date of the Annual Meeting, the Chairman of the Annual Meeting may adjourn the Annual Meeting to permit further solicitations of proxies.

The telephone and Internet voting procedures are designed to authenticate shareholders' identities, to allow shareholders to give their voting instructions and to confirm that shareholders' instructions have been recorded properly. Shareholders voting via the telephone or Internet should understand that there may be costs associated with telephonic or electronic access, such as usage charges from telephone companies and Internet access providers, which must be borne by the shareholder.

**Why is Portillo's holding a virtual Annual Meeting?**

The virtual Annual Meeting is accessible on any Internet-connected device and shareholders will be able to submit questions and comments and to vote online, during the meeting. We believe that a virtual shareholder meeting provides greater access to those who may want to attend and therefore have chosen this over an in-person meeting. In the event of a technical malfunction or other problem that disrupts the Annual Meeting, the Company may adjourn, recess, or expedite the Annual Meeting, or take such other action that the Company deems appropriate considering the circumstances. If you encounter any difficulties accessing the virtual meeting during the meeting, please call (866) 648-8133.

**How do I participate during the Annual Meeting?**

You may virtually attend the Annual Meeting by visiting **www.proxydocs.com/PTLO**, where shareholders will receive additional information on how to vote and submit questions during the Meeting. Please have your Control Number to join the Annual Meeting. Instructions on how to attend and participate via the Internet, including how to demonstrate proof of stock ownership, are posted at **www.proxydocs.com/PTLO**.

Only holders of our common stock at the close of business on the Record Date will be permitted to ask questions during the Annual Meeting. If you wish to submit a question, on the day of the Annual Meeting, you may log into the virtual meeting platform at **www.proxydocs.com/PTLO**, and type your question for consideration into the field provided in the web portal. To allow us to answer questions from as many shareholders as possible, we may limit each shareholder to one (1) question. Questions from multiple shareholders on the same topic or that are otherwise related may be grouped, summarized and answered together. More information on submitting questions at the Annual Meeting will be posted on the internet website **www.proxydocs.com/PTLO** in advance of the meeting.

In accordance with Delaware law, for the 10 days prior to our Annual Meeting, a list of registered holders entitled to vote at our Annual Meeting will be available for inspection in our offices at 2001 Spring Road, Suite 400, Oak Brook, Illinois 60523.

Other Matters

**Who bears the cost of solicitation?**

The expenses of any solicitation of proxies to be voted at the Annual Meeting will be paid by the Company. Following the original mailing of the proxies and other soliciting materials, the Company and its Directors, officers or employees (for no additional compensation) may also solicit proxies in person, by telephone or email. Following the original mailing of the proxies and other soliciting materials, the Company will request that banks, brokers and other nominees forward copies of the proxy and other soliciting materials to persons for whom they hold shares of common stock and request authority for the exercise of proxies. We will reimburse banks, brokers and other nominees for reasonable charges and expenses incurred in forwarding soliciting materials to their clients.

**How do I revoke a proxy?**

Any person submitting a proxy has the power to revoke such proxy prior to the Annual Meeting or at the Annual Meeting prior to the vote. A proxy may be revoked by a writing delivered to the Company stating that the proxy is revoked, by a subsequent proxy that is submitted via telephone or Internet no later than 11:59 p.m. (Central Time) on June 8, 2026, by a subsequent proxy that is signed by the person who signed the earlier proxy and is delivered before or at the Annual Meeting, or by attendance at the Annual Meeting and voting online. If you are a beneficial owner and wish to change any of your previously provided voting instructions, you must contact your bank, broker or other nominee directly.

**What is householding and how does it impact me?**

We have adopted a procedure approved by the SEC called "householding" under which multiple shareholders who share the same address will receive only one copy of the Annual Report, Proxy Statement, or Notice of Internet Availability of Proxy Materials, as applicable, unless we receive contrary instructions from one or more of the shareholders. If you wish to opt out of householding and receive multiple copies of the proxy materials at the same address, you may do so by notifying us by telephone at (866) 648-8133, by email at paper@elections.com or investors@portillos.com, or by mail at Portillo's Inc. at 2001 Spring Road, Suite 400, Oak Brook, Illinois 60523, and we will promptly deliver the requested materials. You also may request additional copies of the proxy materials by notifying us by telephone or in writing at the same telephone number, email address, or mailing address. If you are currently receiving multiple copies of the proxy materials and wish to receive only one copy at the same address, then please notify us by telephone or in writing at the same telephone number, email address, or mailing address. Shareholders with shares registered in the name of a brokerage firm or bank may contact their brokerage firm or bank to request information about householding.

**When will Proxy Materials be electronically delivered to Shareholders?**

Beginning on or about April 20, 2026, we mailed or e-mailed to our shareholders a Notice of Internet Availability of Proxy Materials with instructions on how to access our proxy materials over the Internet and how to vote. If you received such Notice and would prefer to receive paper copies of the proxy materials, or if you received paper copies of the proxy materials and would prefer to receive a notice for future annual meetings, you may notify us by telephone, email or mail at the telephone number, email address and mailing address provided above.

**Appendix A - Reconciliation of Non-GAAP Financial Measures**

**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 are supplemental measures of operating performance and our calculations thereof 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.

The following table reconciles net income to Adjusted EBITDA and Adjusted EBITDA margin (in thousands):

---

| | |
|:---|:---|
| | **Fiscal Year Ended** |
| | **December 28, 2025** |
| Net income | $21092 |
| *Net income margin* | 2.9% |
| Depreciation and amortization | 29112 |
| Interest expense | 22808 |
| Interest income | (275) |
| Income tax expense | 2997 |
| EBITDA | 75734 |
| Deferred rent<sup>(1)</sup> | 6840 |
| Equity-based compensation | 6493 |
| Cloud-based software implementation costs <sup>(2)</sup> | 267 |
| Amortization of cloud-based software implementation costs <sup>(3)</sup> | 1091 |

| Tax Receivable Agreement liability adjustment<sup>(7)</sup> | (2945) |
| Adjusted EBITDA | $97331 |
| *Adjusted EBITDA Margin*<sup>(8)</sup> | 13.3% |

---

<sup>(1)</sup> Represents the difference between cash rent payments and the recognition of straight-line rent expense recognized over the lease term.

<sup>(2)</sup> Represents non-capitalized third-party consulting and software licensing costs incurred in connection with the implementation of a new ERP and HCM systems which are included within general and administrative expenses.

<sup>(3)</sup> Represents amortization of capitalized cloud-based ERP and HCM system implementation costs that are included within general and administrative expenses.

<sup>(4)</sup> Represents loss on disposal of property and equipment, a legacy Barnelli's trade name impairment charge in fiscal 2025, and a technology asset impairment charge in fiscal 2024 included within other loss (income), net.

<sup>(5)</sup> Represents certain expenses that management believes are not indicative of ongoing operations, consisting primarily of certain professional fees included within general and administrative expenses.

<sup>(6)</sup> Represents $4.4 million of costs related to the Company's strategic reset of its development and growth plans, $1.7 million in connection with the departure of our CEO, and $0.4 million in connection with the departure of our Chief Development Officer, which are included within general and administrative expenses.

<sup>(7)</sup> Represents remeasurement of the Tax Receivable Agreement liability.

<sup>(8)</sup> Adjusted EBITDA Margin is defined as Adjusted EBITDA divided by Revenues, net.

**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.

The following table reconciles operating income to Restaurant-Level Adjusted EBITDA and Restaurant-Level Adjusted EBITDA Margin (in thousands):

---

**Cautionary Note Regarding Forward-Looking Statements**

This Proxy Statement contains forward-looking statements, within the meaning of the Private Securities Litigation Reform Act of 1995 ("PSLRA"), which are subject to known and unknown risks, uncertainties and other important factors that may cause actual results to be materially different from the statements made herein. All statements other than statements of historical fact are forward-looking statements. Forward-looking statements discuss our current expectations and projections relating to our financial position, results of operations, plans, objectives, future performance and business. You can identify forward-looking statements by the fact that they do not relate strictly to historical or current facts. These statements may include words such as "aim," "anticipate," "believe," "estimate," "expect," "forecast," "future," "outlook," "potential," "project," "projection," "plan," "intend," "seek," "may," "could," "would," "will," "should," "can," "can have," "likely," the negatives thereof and other similar expressions.

Forward-looking statements are based on our current expectations and assumptions regarding our business, the economy and other future conditions. Because forward-looking statements relate to the future, by their nature, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict. As a result, our actual results may differ materially from those contemplated by the forward-looking statements, so you should not unduly rely on these statements. Important factors that could cause actual results to differ materially from those in the forward-looking statements include regional, national or global political, economic, business, competitive, market and regulatory conditions and the following:

**•** risks related to or arising from our organizational structure;

**•** risks of food-borne illness and food safety and other health concerns about our food;

**•** risks relating to the economy and financial markets, including in relation to trade policy changes and macroeconomic uncertainty, including inflation, fluctuating interest rates, stock market volatility, recession concerns, and other factors;

**•** risks associated with onboarding a new Chief Executive Officer;

**•** the impact of unionization activities of our Team Members on our reputation, operations and profitability;

**•** risks associated with our reliance on certain information technology systems, and potential failures or interruptions;

**•** risks associated with data, privacy, cybersecurity and the use and implementation of information technology systems, including our digital ordering and payment platforms for our off-premise and delivery business;

**•** risks associated with increased adoption, implementation and use of artificial intelligence ("AI") technologies across our business;

**•** the impact of competition, including from our competitors in the restaurant industry or our own restaurants;

**•** the increasingly competitive labor market and our ability to attract and retain the best talent and qualified employees, including executive officers and the other key team members;

**•** the impact of federal, state or local government regulations relating to privacy, data protection, advertising and consumer protection, building and zoning requirements, labor and employment matters, costs of or ability to open new restaurants, or the sale of food and alcoholic beverages;

**•** inability to achieve our growth strategy, such as the availability of suitable new restaurant sites in existing and new markets and opening of new restaurants at the anticipated rate and on the anticipated timeline;

**•** the impact of consumer sentiment and other economic factors on our sales;

**•** increases in food and other operating costs, tariffs and import taxes, and supply shortages; and

**•** other risks identified in our filings with the Securities and Exchange Commission (the "SEC").

All forward-looking statements are expressly qualified in their entirety by these cautionary statements. You should evaluate all forward-looking statements made in this Proxy Statement in the context of the risks and uncertainties disclosed in our Annual Report on Form 10-K for the fiscal year ended December 28, 2025 filed with the SEC on February 24, 2026, which is available on the SEC's website at **www.sec.gov**.

The forward-looking statements included in this Proxy Statement are made only as of the date hereof. The Company undertakes no obligation to publicly update or revise any forward-looking statement as a result of new information, future events or otherwise, except as otherwise required by law.
