Portillo's Inc.

This Quarterly Report on Form 10-Q ("Form 10-Q") 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. Many of the forward-looking statements are located in Part I, Item 2 of this Form 10-Q under the heading "Management's Discussion and Analysis of Financial Condition and Results of Operations." 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 we may not predict. As a result, our actual results may differ materially from those contemplated by the forward-looking statements, and 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 and tax policy changes and other macroeconomic uncertainty, including inflation, fluctuating interest rates, stock market volatility, recession concerns, and other factors;

•risks associated with onboarding new members of management, including the 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;

•inability to achieve our growth strategy, including as a result of, among other things, 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;

•fluctuation 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").
