*For the quarter ended March 31, 2024, same-restaurant sales compares the 13 weeks from January 1, 2024 through March 31, 2024 to the 13 weeks from January 2, 2023 through April 2, 2023.

**Adjusted EBITDA and Restaurant-Level Adjusted EBITDA are non-GAAP measures. Please see definitions and the reconciliations of these non-GAAP measures accompanying this release.

Secondary Offering

In the first quarter of 2024, the Company completed a secondary offering of 8,000,000 shares of the Company's Class A common stock at an offering price of $14.37 per share ("Q1 2024 Secondary Offering"). The net proceeds from this offering were used to purchase LLC Units or shares of Class A common stock, as applicable, of the selling stockholders in a "synthetic secondary" transaction, at a price per LLC Unit or share of Class A common stock. Accordingly, the Company did not receive any proceeds from this offering.

Recent Developments and Trends

In the quarter ended March 31, 2024 total revenue grew 6.3% or $9.8 million. Same-restaurant sales declined 1.2% during the quarter ended March 31, 2024, compared to 9.1% same-restaurant sales growth during the same quarter in 2023.

During the quarter ended March 31, 2024, we opened one new restaurant in Denton, Texas for a total of 85 restaurants, including a restaurant owned by C&O Chicago, L.L.C. ("C&O"), of which Portillo's owns 50% of the equity. The twelve restaurants opened in 2023 and one restaurant opened during the quarter ended March 31, 2024 positively impacted revenues by approximately $14.4 million in the quarter ended March 31, 2024. We opened one restaurant subsequent to March 31, 2024 and plan to open at least seven additional restaurants during the remainder of 2024.

In the quarter ended March 31, 2024, commodity inflation was 4.8%, compared to 8.9% for the quarter ended March 26, 2023. For the quarter ended March 31, 2024, we experienced an increase in labor expenses, as a percentage of revenue, compared to the quarter ended March 26, 2023 primarily due to lower transactions and incremental wage rate increases to support our team members, partially offset by increase in our average check and lower variable-based compensation. We increased certain menu prices by approximately 1.5% during both January of 2024 and at the end of March 2024 to offset inflationary cost pressures. We will continue to monitor cost pressures, the competitive landscape, and consumer sentiment to inform our pricing decisions in the future quarters.

In the quarter ended March 31, 2024, operating income, operating margin, net income, Restaurant-Level Adjusted EBITDA, Adjusted EBITDA and Adjusted EBITDA margin all improved versus the prior year. We believe this improvement was the result of our ongoing efforts to elevate guest experiences, deploy strategic pricing actions, implement operational efficiencies, and grow our restaurant base. Further, we intend to continue focusing our efforts on running world class operations, innovating and amplifying the Portillo's experience, building restaurants with industry-leading returns and taking great care of our teams.

We also launched two new salads to our menu in late March as a result of guest feedback. The Spicy Chicken Chopped Salad and the Chicken Pecan Salad with Bacon are fresh made-to-order salads that joined our menus nationwide alongside other fan-favorite salads, including the Greek Salad, Caesar Salad and our famous original Chopped Salad. Additionally, to promote our new salads we will introduce a new brown paper bag with green stripes for a limited time in May and June. Like our prior bag, the new bag is also 100% recyclable, does not need to be bleached, and is made from fibers certified by the Sustainable Forestry Initiative.

Review of First Quarter 2024 Financial Results

Revenues for the first quarter ended March 31, 2024 were $165.8 million compared to $156.1 million for the first quarter ended March 26, 2023, an increase of $9.8 million or 6.3%. The increase in revenues was primarily attributed to the opening of twelve restaurants in 2023 and one restaurant during the quarter ended March 31, 2024, partially offset by a decrease in our same-restaurant sales. New restaurants positively impacted revenues by approximately $14.4 million in the quarter ended March 31, 2024. Same-restaurant sales decreased 1.2% during the first quarter ended March 31, 2024, which was attributable to a 3.2% decrease in transactions, partially offset by an increase in average check of 2.0%. The higher average check was driven by an approximate 5.1% increase in certain menu prices partially offset by product mix. For the purpose of calculating same-restaurant sales for March 31, 2024, sales for the 69 restaurants that were open for at least 24 full fiscal periods were included in the Comparable Restaurant Base (as defined below).

Total restaurant operating expenses for the first quarter ended March 31, 2024 were $129.5 million compared to $121.2 million for the first quarter ended March 26, 2023, an increase of $8.2 million or 6.8%. The increase in restaurant operating expenses was driven by the opening of twelve restaurants in 2023 and one restaurant during the quarter ended March 31, 2024. Additionally, food, beverage and packaging costs were negatively impacted by a 4.8% increase in commodity prices. Labor expense increases were also driven by incremental investments to support our team members, including annual rate increases, partially offset by lower variable-based compensation. Operating expenses increased due to an increase in cleaning expenses, credit card fees and utilities, partially offset by lower advertising expenses and a decrease in operating supplies.

General and administrative expenses for the first quarter ended March 31, 2024 were $18.5 million compared to $18.8 million for the first quarter ended March 26, 2023, a decrease of $0.2 million or 1.3%. This decrease was primarily driven by lower equity-based compensation and lower variable-based compensation, partially offset by an increase in salaries and wages attributable to annual rate increases, increases in professional fees, and increases to advertising and marketing expenses.

Operating income for the first quarter ended March 31, 2024 was $10.1 million compared to $8.5 million for the first quarter ended March 26, 2023, an increase of $1.6 million due to the aforementioned increase in revenues, partially offset by increases in the aforementioned expenses.

Net income for the first quarter ended March 31, 2024 was $5.3 million compared to a net loss of $1.3 million for the first quarter ended March 26, 2023, an increase of $6.6 million. The increase in net income was primarily due the $3.5 million loss on debt extinguishment in the prior year, an increase in operating income of $1.6 million due to the aforementioned factors, a decrease in interest expense of $0.9 million, increase in income tax benefit of $0.6 million, and an increase in interest income of $0.1 million.

Restaurant-Level Adjusted EBITDA* for the first quarter ended March 31, 2024 was $36.4 million compared to $34.8 million for the quarter ended March 26, 2023, an increase of $1.6 million or 4.5%.

Adjusted EBITDA* for the first quarter ended March 31, 2024 was $21.8 million compared to $19.6 million for the quarter ended March 26, 2023, an increase of $2.1 million or 10.9%.

*A reconciliation of Restaurant-Level Adjusted EBITDA and Adjusted EBITDA and the nearest GAAP financial measure is included under "Non-GAAP Measures" in the accompanying financial data below.

Development Highlights

During the quarter ended March 31, 2024, we opened one restaurant in the Texas market. Subsequent to March 31, 2024, we opened one additional restaurant, bringing our total restaurant count to 86, including a restaurant owned by C&O of which Portillo's owns 50% of the equity.

Below are the restaurants opened since the beginning of fiscal 2024:

Location	Opening Date	Fiscal Quarter Opened
Denton, Texas	March 2024	Q1 2024
Surprise, Arizona	May 2024	Q2 2024

The following definitions apply to these terms as used in this release:

Change in Same-Restaurant Sales - The change in same-restaurant sales is the percentage change in year-over-year revenue (excluding gift card breakage) for the Comparable Restaurant Base, which is defined as the number of restaurants open for at least 24 full fiscal periods. For the quarters ended March 31, 2024 and March 26, 2023, there were 69 and 63 restaurants in our Comparable Restaurant Base, respectively.

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

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

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

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. See also "Non-GAAP Financial Measures."

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. See also "Non-GAAP Financial Measures".

For more information about the Company's Non-GAAP measures, how they are calculated and reconciled and why management believes that they are useful, see "Non-GAAP Financial Measures" below.

PORTILLO'S INC.

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, Restaurant-Level Adjusted EBITDA and Restaurant-Level Adjusted EBITDA Margin 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 stockholders 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 total revenues.

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.

We are unable to reconcile the long-term outlook for Adjusted EBITDA to net income (loss), the corresponding U.S. GAAP measure, due to variability and difficulty in making accurate forecasts and projections and because not all information necessary to prepare the reconciliation is available to us without unreasonable efforts. For the same reasons, we are unable to address the probable significance of the unavailable information because we cannot accurately predict all of the components of the adjusted calculations and the non-GAAP measure may be materially different than the GAAP measure.

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

Restaurant-Level Adjusted EBITDA is defined as revenue, less restaurant operating expenses, which include cost of goods sold (excluding depreciation and amortization), 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.
