Engaged Capital Nominates Two Highly Qualified, Independent Candidates for Election to Portillo's Board of Directors

Nominates Charlie Morrison, Who Delivered Total Shareholder Returns of ~760% During His Tenure as CEO of Wingstop, and Nicole Portwood, an Experienced Marketing Executive and Former CMO of Tito's Handmade Vodka, to Company's Board

Nominees Possess Necessary Restaurant Operations and Marketing Experience to Drive Greater Urgency on Enhancing Company Performance

Engaged Capital, LLC (together with certain of its affiliates, "Engaged" or "we"), which beneficially owns approximately 8.6% of the outstanding Class A common stock of Portillo's Inc. (NASDAQ:PTLO) ("Portillo's" or the "Company"), today announced that it has nominated two highly qualified, independent candidates for election to the Company's Board of Directors (the "Board") at the 2025 Annual Meeting of Stockholders (the "Annual Meeting"). In connection with its nomination, Engaged issued the following statement:

"Engaged is one of the largest stockholders of Portillo's because we believe the Company has a clear path to delivering enhanced value for stockholders. Portillo's is an iconic brand with beloved restaurants that possesses a number of attributes that set the foundation for highly profitable long-term growth, including:

1. Industry-leading average unit volumes, or AUVs;
2. High-quality and differentiated food and beverages offered at compelling value; and
3. Proven portability of the concept based on new store volumes in expansion markets where overall awareness is still very low
   
   
   
   

Despite these tailwinds for value creation and a rich legacy as a Chicago classic, the Company's performance appears to be suffering due to outdated restaurant operations, ineffective marketing and lower than justified restaurant-level cash-on-cash returns. Although these issues have led to a depressed valuation for the Company, they are all readily fixable.

Based on our own analysis and engagement with Portillo's, we believe the Company has a significant runway to increase same-store sales and profitably grow restaurant units. We are encouraged by recent initiatives to address the Company's challenges, including the addition of long-time Chipotle CFO Jack Hartung to the Board. Ultimately, however, we contend the magnitude of value creation at Portillo's will depend on leadership's ability to execute key initiatives with precision and urgency. The Company needs to refine its approach to new unit development, modernize restaurant operations and related technology, and deploy targeted marketing investments to increase awareness and drive traffic.

We are confident that electing new directors, who possess recent restaurant operations and marketing experience, will dramatically improve Portillo's ability to execute and close the gap with industry peers. That is why we have nominated two highly qualified, independent candidates – Charlie Morrison and Nicole Portwood – whose backgrounds are ideally suited to help resolve these issues on an expedited basis. Mr. Morrison's experience as a world-class restaurant operator, who delivered total shareholder returns of ~760% during his tenure as CEO of Wingstop, and Ms. Portwood's marketing expertise for household brands, including Tito's, Mountain Dew and Live Nation, will be extremely additive to the Board.¹

It is important to stress that we were forced to resort to this public nomination after months of unsuccessful private discussions focused on adding Mr. Morrison to the Board. Much like we have in other engagements with our portfolio companies, we remain ready and willing to reach a constructive resolution that spares all stakeholders an election contest. We believe the anchor for this type of resolution is further incremental change to the Board. A strengthened boardroom with collaborative and experienced restaurant executives, like Mr. Morrison and Ms. Portwood, is a win-win for all of Portillo's stockholders and stakeholders."
