[10-Q] Portillo's Inc. Quarterly Earnings Report

Rhea-AI Filing Summary

Portillo’s Inc. (PTLO) reported softer Q3 results. Revenue was $181.4 million, up 1.8% year over year, while same-restaurant sales declined 0.8% as transactions fell 2.2% and average check rose 1.4%. Operating income fell to $5.4 million from $16.0 million, and net income was $0.8 million versus $8.8 million a year ago; diluted EPS was $0.02.

Costs weighed on margins: food and packaging were 34.5% of revenue, labor 26.6%, and other operating expenses 12.9%. The quarter also included a non-cash $2.2 million trade name impairment tied to the legacy Barnelli’s brand and equity-compensation impacts related to the CEO transition. Year-to-date, revenue was $546.3 million (up 3.9%) with net income of $14.8 million (down from $22.6 million).

Management announced a strategic reset to reinforce value and service, simplify operations (including discontinuing a Chicago breakfast pilot), moderate new unit growth, and target positive free cash flow in 2026. Four restaurants opened in Q3 (99 total as of the filing). Liquidity included $17.2M in cash and a refreshed credit facility (term loan and revolver) with $77.0M drawn on the revolver and effective interest near 6.9% at quarter end.

Insights

Restaurant industry analyst

Low growth, margin pressure, and a reset to prioritize cash.

Portillo’s delivered modest Q3 revenue growth to $181.4M but saw traffic softness, with same-restaurant sales down 0.8%. Pricing and mix lifted average check, yet inflation and newer-unit deleverage raised food (34.5% of sales) and labor (26.6%) ratios, compressing operating income to $5.4M.

Non-cash items also affected results: a $2.2M impairment for the Barnelli’s trade name and equity-based compensation adjustments related to the CEO transition. The effective tax rate spiked to 268.2% given quarterly dynamics. Debt was refinanced earlier in the year into a $250M term loan and $150M revolver; revolver borrowings were $77.0M.

The announced strategic reset targets transactions, operational simplicity, a measured pace of openings, and positioning for positive free cash flow in 2026. Actual impact will depend on execution and demand trends across core markets.

Cautionary Note Regarding Forward-Looking Information

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 our recently announced search for a new Chief Executive Officer and the related transition;

•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, including our new enterprise resource planning system, and potential failures or interruptions;

•risks associated with data, privacy, cyber security and the use and implementation of information technology systems, including our digital ordering and payment platforms for our delivery business;

•risks associated with increased adoption, implementation and use of artificial intelligence 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;

•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, 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;

•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 Form 10-Q in the context of the risks and uncertainties disclosed in our Annual Report on Form 10-K for the fiscal year ended December 29, 2024 filed with the SEC on February 25, 2025, and subsequent filings with the SEC, which are available on the SEC's website at www.sec.gov.

The forward-looking statements included in this Form 10-Q 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.

PORTILLO'S INC.

NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1.    DESCRIPTION OF BUSINESS

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

The Company operates restaurants in 10 states that serve Chicago-style hot dogs and sausages, Italian beef sandwiches, char-grilled burgers, chopped salads, crinkle-cut fries, homemade chocolate cake and more, along with two food production commissaries in Illinois. As of September 28, 2025, the Company had 97 restaurants in operation. The Company also had one non-traditional location in operation, a food truck. Portillo's additionally has a 50% interest in a single restaurant owned by C&O Chicago, L.L.C. ("C&O"), which is excluded from the Company's restaurant count noted above. The Company’s principal corporate offices are located in Oak Brook, Illinois.

The Company entered into a joint venture agreement to develop and operate a restaurant at the Dallas-Fort Worth International Airport ("DFW") which is expected to commence operations in 2026. The Company holds a 65% ownership interest in AP Dogs, LLC ("AP Dogs") and has day-to-day operational and managerial control over its business and affairs. Accordingly, the Company consolidates the joint venture and reports a noncontrolling interest representing the economic interest in AP Dogs held by the other partner.

NOTE 2.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The Company has prepared the accompanying unaudited condensed consolidated financial statements in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial statements and pursuant to the rules and regulations of the Securities and Exchange Commission (the "SEC"). In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments consisting of normal recurring adjustments necessary for a fair presentation of our financial position and results of operations. Interim results of operations are not necessarily indicative of the results that may be achieved for the full year. The financial statements and related notes do not include all information and footnotes required by GAAP for annual reports. The unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the fiscal year ended December 29, 2024.

All intercompany balances and transactions have been eliminated in consolidation.

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

Fiscal Year

The Company uses a 52- or 53-week fiscal year ending on the Sunday prior to or on December 31. In a 52-week fiscal year, each quarterly period is comprised of 13 weeks. An additional week in a 53-week fiscal year is added to the fourth quarter. Fiscal 2025 and 2024 consist of 52 weeks. The fiscal periods presented in this report are the quarter and three quarters ended September 28, 2025 and September 29, 2024, respectively.

Use of Estimates

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

Goodwill and indefinite-lived intangible assets are assessed for impairment annually in the fourth quarter or more frequently if events and circumstances indicate that it is more likely than not that the fair value of a reporting unit or an intangible asset is less than its carrying value.

In the quarter ended September 28, 2025, management identified impairment indicators that required a quantitative assessment of goodwill outside of the Company's annual impairment test. These indicators included the announcement of a strategic reset of the Company’s development and growth plan, which resulted in revised financial targets for fiscal year 2025 and the announced departure of the Company’s President and Chief Executive Officer, effective September 21, 2025. Based on these factors and information available, the Company determined that an interim quantitative test of goodwill and indefinite-lived intangible assets for impairment should be performed as of September 28, 2025.

The Company has one reporting unit and the fair value of the reporting unit was estimated using a weighted combination of the income and market approaches. Under the income approach, the Company uses a discounted cash flow methodology, which requires management to make significant estimates and assumptions related to forecasted revenues, EBITDA margins, capital expenditures, perpetual growth rates, and long-term discount rates, among others. The market approach incorporated both the guideline public company method and the guideline transaction method. The guideline public company method involves analyzing valuation multiples of comparable publicly traded companies with similar operating and investment characteristics, while the guideline transaction method considers transaction multiples observed for comparable businesses. The Company also reconciles the fair value of its reporting unit to its current market capitalization to assess reasonableness. If the fair value of the reporting unit is less than its carrying value, an impairment loss is recorded for the difference between the fair value of the reporting unit and the carrying value of the reporting unit. Upon completion of the quantitative impairment test and review of the related results in connection with the preparation of this Quarterly Report on Form 10-Q, the Company determined that the fair value of the reporting unit exceeded its carrying value by approximately 19%. Accordingly, the Company concluded that no impairment of goodwill existed as of the quarter and three quarters ended September 28, 2025.

The Company’s indefinite-lived intangible assets consist of trade names and trademarks (collectively, the “trade names”). The Company estimates the fair value of its trade names using a relief-from-royalty income approach. If the fair value of the trade name is less than its carrying value, an impairment loss is recorded for the difference between the estimated fair value and carrying value of the intangible assets. In the quarter ended September 28, 2025, due to the impairment indicators mentioned above, the Company also tested its trade names for impairment in connection with the preparation of this Quarterly Report on Form 10-Q. As a result, the Company recorded a non-cash impairment charge of $2.2 million related to its legacy Barnelli's trade name, a pasta concept available at nine co-branded restaurants, during the quarter and three quarters ended September 28, 2025. This impairment charge is included within other loss (income), net in the condensed consolidated statements of operations.

Recently Issued Accounting Standards

In December 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-09, Income Taxes (Topic 740) Improvements to Income Tax Disclosures, which requires public entities to disclose specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold on an annual basis. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024. We will adopt ASU 2023-09 in our Annual Report on From 10-K for the year ending December 28, 2025. The adoption of ASU 2023-09 will not have an impact on our financial condition or results of operations but will change certain disclosures in our financial statements related to income taxes.

In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires disaggregation of certain expense captions into specified categories in disclosures within the footnotes to the financial statements. In January 2025, the FASB issued ASU 2025-01 "Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures-Clarifying the Effective Date", which amends the effective date of ASU 2024-03 to clarify that all public business entities are required to adopt the guidance in annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the effect of adopting this ASU.

In September 2025, the FASB issued ASU 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which updates the cost capitalization threshold for internal-use software development costs by removing all references to software project development stages and providing new guidance on how to evaluate whether the probable-to-complete recognition threshold has been met. ASU 2025-06 is effective for fiscal years beginning after December 15, 2027, with

Recently Adopted Accounting Standards

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280) Improvements to Reportable Segment Disclosures, which requires public entities to disclose information about their reportable segments’ significant expenses on an interim and annual basis. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company adopted this standard for the year ended December 29, 2024. Refer to Note 14. Segment Information for further detail.

The Company reviewed all other recently issued accounting pronouncements and concluded that they were either not applicable or not expected to have a significant impact to its condensed consolidated financial statements.

NOTE 3.    REVENUE RECOGNITION

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

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

Gift Cards

The Company sells gift cards which do not have expiration dates. The Company records the sale of the gift card as a contract liability and recognizes revenue from gift cards when: (i) the gift card is redeemed by the customer; or (ii) in the event a gift card is not expected to be redeemed, in proportion to the pattern of rights exercised by the customer (gift card breakage). The Company has determined that 11% of gift card sales will not be redeemed and will be retained by us based on a portfolio assessment of historical data on gift card redemption patterns. Gift card breakage is recorded within revenues, net in the condensed consolidated statements of operations. The Company recognized gift card breakage of $0.2 million and $0.7 million for the quarter and three quarters ended September 28, 2025 and September 29, 2024, respectively.

The Company’s revenue related to performance obligations not yet satisfied is revenue from gift cards sold but not yet redeemed. The gift card liability included in deferred revenue on the condensed consolidated balance sheets is as follows (in thousands):

			September 28, 2025						December 29, 2024
Gift card liability			$	3,972					$	6,875

Loyalty Program

On March 3, 2025, the Company launched Portillo’s Perks™, an app-less loyalty program that lives in guests’ digital wallets. The loyalty program (“Perks”) is a visit-based program, and guests earn rewards based on qualified visits.

The Company defers revenue based on the average selling price of food, beverages, or retail merchandise earned through qualifying visits, establishing a corresponding Perks liability within deferred revenue on the condensed consolidated balance sheets. Currently, the Company does not record breakage due to the short expiration period of 14 to 30 days after the reward is issued. Upon redemption of Perks, revenue is recognized for redeemed food, beverage, or retail merchandise, and the Perks liability is reduced accordingly. As of September 28, 2025, the Perks liability was $0.1 million.

NOTE 7.    FAIR VALUE OF FINANCIAL INSTRUMENTS

Assets and Liabilities Measured at Fair Value on a Recurring Basis

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

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

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

As of September 28, 2025 and December 29, 2024, the fair value of the mutual fund investments and deferred compensation obligations were as follows (in thousands):

			September 28, 2025						December 29, 2024
			Level 1																		Level 1
Assets - Investments designated for deferred compensation plan
Cash accounts			$	875																	$	988
Mutual funds			2,128																		2,208
Total assets			$	3,003																	$	3,196

As of September 28, 2025 and December 29, 2024, we had no Level 2 or Level 3 assets.

The deferred compensation investments and obligations are included in other assets, accrued expenses and other long-term liabilities in the consolidated balance sheets. Changes in the fair value of securities held in the rabbi trust are recognized as trading gains and losses and included in other income in the condensed consolidated statements of operations and offsetting increases or decreases in the deferred compensation obligation are recorded in accrued expenses and other long-term liabilities in the condensed consolidated balance sheets.

Refer to Note 8. Debt for additional information relating to the fair value of the Company's outstanding debt instruments.

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

Assets and liabilities that are measured at fair value on a non-recurring basis include property and equipment, net, operating lease assets, equity-method investment, goodwill and indefinite-lived intangible assets. These assets are measured at fair value whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. During the quarter and three quarters ended September 28, 2025, the Company recognized trade name impairment charges of $2.2 million, included within other loss (income), net in the consolidated statement of operations. Refer to Note 2. Summary Of Significant Accounting Policies for further information. There were no impairment charges recognized during the quarter and three quarters ended September 29, 2024.

2025 Credit Agreement

On January 27, 2025 (the “2025 Credit Agreement Closing Date”), PHD Intermediate LLC ("Holdings"), Portillo’s Holdings LLC (the "Borrower"), the other Guarantors party thereto, the Lenders from time to time party thereto and Fifth Third Bank, National Association, as Administrative Agent (in such capacities, the "Administrative Agent"), the L/C Issuer and the Swing Line Lender entered into an amendment (the “Amendment”) to the credit agreement, dated as of February 2, 2023 (the "Existing Credit Agreement" and the Existing Credit Agreement as amended by the Amendment and as may be amended, restated, supplemented or otherwise modified from time to time thereafter, the "2025 Credit Agreement"), by and among Holdings, the Borrower, the other Guarantors from time to time party thereto, the Lenders from time to time party thereto and the Administrative Agent. The arrangement was accounted for as a debt modification.

The Existing Credit Agreement provided for a term A loan (the "2023 Term Loan") in an initial aggregate principal amount of $300.0 million and revolving credit commitments in an initial aggregate principal amount of $100.0 million (the "2023 Revolver Facility"). The Amendment provides for, among other things, (i) a $250 million term loan A facility (the “2025 Term Loan”) and (ii) revolving credit commitments in an initial aggregate principal amount of $150 million (the “2025 Revolver Facility” and, together with the Term Loan Facility, the “2025 Facilities”). The loans under each of the 2025 Facilities mature on January 27, 2030.

The 2023 Term Loan and 2023 Revolver Facility accrued, and the 2025 Term Loan and 2025 Revolver Facility accrue interest at the forward-looking secured overnight financing rate ("SOFR") plus an applicable rate determined upon the consolidated total net rent adjusted leverage ratio, in each case subject to a 0.00% floor.

As of September 28, 2025, the interest rate on the 2025 Term Loan and 2025 Revolver Facility was 6.55% and 6.57%, respectively. Pursuant to the 2025 Credit Agreement, as of September 28, 2025, the commitment fees to maintain the 2025 Revolver Facility were 0.20%, and letter of credit fees were 2.25%. Commitment fees and letter of credit fees are recorded as interest expense in the condensed consolidated statements of operations. As of September 28, 2025, the effective interest rate was 6.90%.

As of September 29, 2024, the interest rates on the 2023 Term Loan and 2023 Revolver Facility were 7.98% and 7.85%, respectively. Pursuant to the Existing Credit Agreement as of September 29, 2024, the commitment fees to maintain the 2023 Revolver Facility were 0.20% and letter of credit fees were 2.50%. As of September 29, 2024, the effective interest rate was 8.32%.

The 2025 Term Loan Facility will amortize in quarterly installments, commencing on the last day of the first full fiscal quarter ended after the 2025 Credit Agreement Closing Date, equaling an aggregate amount of $6.3 million for the first 2 years following the 2025 Credit Agreement Closing Date, (ii) $12.5 million for the third and fourth years following the 2025 Credit Agreement Closing Date and (iii) $25.0 million for the fifth year following the 2025 Credit Agreement Closing Date, with the balance payable on the final maturity date.

As of September 28, 2025, outstanding borrowings under the 2025 Credit Agreement totaled $325.4 million, comprised of $248.4 million under the 2025 Term Loan, and $77.0 million under the 2025 Revolver Facility. Letters of credit issued under the 2025 Revolver Facility totaled $4.4 million. As a result, as of September 28, 2025, the Company had $68.6 million available under the 2025 Revolver Facility.

As of December 29, 2024, outstanding borrowings under the Existing Credit Agreement totaled $313.8 million, comprised of $288.8 million under the 2023 Term Loan, and $25.0 million under the 2023 Revolver Facility. Letters of credit issued under the 2023 Revolver Facility totaled $5.3 million. As a result, as of December 29, 2024, the Company had $69.7 million available under the 2023 Revolver Facility. All amounts

outstanding under the 2023 Term Loan and 2023 Revolver Facility were refinanced in connection with the Amendment.

Discount, Debt Issuance Costs and Interest Expense

Pursuant to the 2025 Credit Agreement, the Company capitalized deferred financing costs and issuance discounts of $1.3 million. The remaining unamortized costs under the 2023 Credit Agreement were $2.0 million. The total deferred financing costs and issuance discounts of $3.3 million will be amortized over the term of the 2025 Credit Agreement.

The Company amortized an immaterial amount of deferred financing costs during both the quarters ended September 28, 2025 and September 29, 2024, and $0.1 million of deferred financing costs during both the three quarters ended September 28, 2025 and September 29, 2024, which is included in interest expense in the condensed consolidated statements of operations. In addition, the Company amortized $0.2 million and $0.4 million in original issue discount related to the long-term debt during the quarter and three quarters ended September 28, 2025, respectively, and $0.2 million and $0.5 million in the quarter and three quarters ended September 29, 2024, respectively, which is included in interest expense in the condensed consolidated statements of operations.

Fair Value of Debt

As of September 28, 2025 and December 29, 2024, the fair value of long-term debt approximates the carrying value as it is variable rate debt. The fair value measurement of this debt is considered Level 2 of the fair value hierarchy as inputs to interest are observable, unadjusted quoted prices in active markets for similar assets or liabilities.

Guarantees and Covenants

The 2025 Credit Agreement contains customary representations and warranties, events of default, reporting and other affirmative covenants and negative covenants, including limitations on indebtedness, liens, investments, negative pledges, dividends, junior financings and other fundamental changes. The 2025 Facilities are guaranteed, subject to customary exceptions, by all of the Borrower’s wholly-owned domestic restricted subsidiaries and Holdings, and are secured by a lien on substantially all of the Borrower’s assets, including fixed assets and intangibles, and the assets of the Guarantors, in each case, subject to customary exceptions. Failure to comply with these covenants and restrictions could result in an event of default under the 2025 Credit Agreement. In such an event, all amounts outstanding under the 2025 Credit Agreement, together with any accrued interest, could then be declared immediately due and payable.

As of September 28, 2025, the Company was in compliance with the financial covenants in the 2025 Credit Agreement.

NOTE 9.     NON-CONTROLLING INTERESTS

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

During the three quarters ended September 28, 2025, the Company granted 689,041 RSUs, under the Portillo's Inc. 2021 Equity Incentive Plan (the "2021 Plan") to certain employees. During the three quarters ended September 28, 2025, we also granted 93,725 RSUs to non-employee directors under the 2021 Plan. The weighted average fair value of these awards was determined using the Company's closing stock price on the applicable grant dates, which was $11.55. The RSUs granted to employees will generally vest one-third on each of the first three anniversaries of the date of grant subject to continued service on such date. The RSUs granted to non-employee directors will vest at the end of this year.

Stock Options

During the three quarters ended September 28, 2025, the Company granted 307,692 stock options under the 2021 Plan, to its former President and Chief Executive Officer. In accordance to the Separation Agreement, all of Mr. Osanloo's stock options granted under the 2021 Plan were forfeited effective September 21, 2025.

Performance Stock Units

During the three quarters ended September 28, 2025, the Company granted 301,118 performance stock units ("PSUs") to its executive officers under the 2021 Plan. These PSUs will vest after the fiscal year ending December 26, 2027 based on continued service and the achievement of performance metrics. The amount of awards that can be earned ranges from 0% to 200% of the number of performance stock units granted, based on the achievement of approved financial goals tied to the cumulative growth of revenue and Adjusted EBITDA from fiscal year 2025 to fiscal year 2027. The fair value of these awards was determined using the Company's closing stock price on the date of grant of $12.08. Equity-based compensation costs associated with these PSUs are reassessed each reporting period based on estimated performance achievement. The cumulative effect on current and prior periods of a change in attainment is recognized in general and administrative expenses in the consolidated statements of operations in the period of change.

NOTE 11.    INCOME TAXES

We are the sole managing member of Portillo's OpCo, and as a result, consolidate the financial results of Portillo's OpCo. Portillo's OpCo is treated as a partnership for U.S. federal and most applicable state and local income tax purposes. As a partnership, Portillo's OpCo is generally not subject to U.S. federal and state and local income taxes. Any taxable income or loss generated by Portillo's OpCo is passed through to and included in the taxable income or loss of its members, including us, based upon the respective member's ownership percentage in Portillo's OpCo. We are subject to U.S. federal income taxes, in addition to state and local income taxes with respect to our allocable share of any taxable income or loss of Portillo's OpCo, as well as any stand-alone income or loss generated by Portillo's Inc.

Income Tax Expense

The effective income tax rate for the quarter and three quarters ended September 28, 2025 was 268.2% and 20.4%, respectively, and 22.4% and 17.8%, respectively, for the quarter and three quarters ended September 29, 2024. The increase in our effective income tax rate for the quarter ended September 28, 2025 compared to the quarter ended September 29, 2024 was primarily driven by the decrease in the valuation allowance related to the separation of Mr. Osanloo. This increases the effective income tax rate because the Company recorded a pre-tax loss for the quarter ended September 28, 2025. The increase in our effective income tax rate for the three quarters ended September 28, 2025 compared to the three quarters ended September 29, 2024 was primarily driven by an increase in the Company's ownership interest in Portillo's OpCo, which increases its share of taxable income (loss) of Portillo's OpCo. The Company’s annual effective tax rate differs from the statutory rate of 21% primarily because of state and local taxes, deferred tax adjustments and impacts from equity-based award activity partially offset by the portion of Portillo's OpCo earnings that are attributable to non-controlling interest that the Company is not liable for federal or state income taxes.

We evaluate the realizability of our deferred tax assets on a quarterly basis and establish valuation allowances when it is more likely than not that all or a portion of a deferred tax asset may not be realized. As of September 28, 2025, the Company concluded, based on the weight of all available positive and negative evidence, that all of its deferred tax assets (except for those deferred tax assets relating to the basis difference in its investment in Portillo's OpCo that will never be realizable or only reverse upon the eventual sale of its interest in Portillo's OpCo, which we expect would result in a capital loss which we do not expect to be able to utilize) are more likely than not to be realized.

Tax Receivable Agreement

As of September 28, 2025, we estimated that our obligation for future payments under the TRA liability totaled $353.2 million. During the three quarters ended September 28, 2025 and September 29, 2024, the Company made TRA payments of $7.7 million relating to tax year 2023 and $4.4 million relating to tax year 2022, respectively.

One Big Beautiful Bill Act

On July 4, 2025, the One Big Beautiful Bill Act (the "Act") was signed into law. The Act includes significant provisions, such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act, modifications to the international tax framework and the restoration of favorable tax treatment for certain business provisions. The legislation has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. We have evaluated the potential effects of the relevant provisions of the Act and do not expect a significant financial statement impact as a result of the Act.

NOTE 12.    EARNINGS PER SHARE

Basic net earnings per share of Class A common stock is computed by dividing net income attributable to Portillo's Inc. by the weighted-average number of Class A common stock outstanding.

Diluted net earnings per share is computed by dividing net income attributable to Portillo's Inc. by the weighted-average number of dilutive securities, using the treasury stock method.

The computations of basic and diluted earnings per share for the quarter and three quarters ended quarters ended September 28, 2025 and September 29, 2024 are as follows (in thousands):

NOTE 13.    CONTINGENCIES

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

On September 3, 2024, a former team member from one of the Company's two California restaurants filed a class action lawsuit alleging wage and hour violations and unfair competition, as well as claims under the California Private Attorneys General Act (“PAGA”). At this time a loss is reasonably possible but not estimable, and as a result, no litigation reserve has been recorded on our condensed consolidated balance sheet as of September 28, 2025.

NOTE 14.    SEGMENT INFORMATION

The Company's chief operating decision maker (the "CODM") is its Interim Chief Executive Officer. As the CODM reviews financial performance and allocates resources at a consolidated level on a recurring basis, the Company has one operating segment and one reportable segment.

The CODM allocates resources and assesses performance of the Company based on net income (loss), as reported on the condensed consolidated statement of operations, which as the segment measure of profit and loss that is closest to GAAP, is the required segment measure. Net income was $0.8 million and $14.8 million for the quarter and three quarters ended September 28, 2025, respectively, and $8.8 million and $22.6 million for the quarter and three quarters ended September 29, 2024, respectively. In addition to net income (loss), the CODM also reviews revenue, operating income (loss), restaurant-level adjusted EBITDA, and adjusted EBITDA.

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

The CODM does not review segment assets and segment expenses at a level different than what is reported in the Company's condensed consolidated balance sheet and condensed consolidated statement of operations. Additionally, the CODM regularly receives information about the Company's capital expenditures which are reported in the Company's condensed consolidated statement of cash flows as purchase of property and equipment under investing activities.

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

Overview

Portillo’s serves iconic Chicago street food in high-energy, multichannel restaurants designed to ignite the senses and create memorable dining experiences. Since our founding in 1963 in a small trailer called “The Dog House,” we have grown to become a treasured brand with a passionate (some might say obsessed) nationwide following. Our diverse menu features all-American favorites such as Chicago-style hot dogs and sausages, Italian beef sandwiches, char-broiled burgers, fresh chopped salads, crinkle-cut fries, homemade chocolate cake and our signature chocolate cake shake. We create a consumer experience like no other by combining the best attributes of fast-casual and quick-service concepts with an exciting energy-filled atmosphere in a restaurant model capable of generating tremendous volumes. Nearly all of our restaurants were built with double lane drive-thrus and have been thoughtfully designed with a layout that accommodates a variety of access modes including dine-in, carryout, delivery and catering to quickly and efficiently serve our guests. We believe the combination of our craveable food, multichannel sales model, dedication to operational excellence, and distinctive team member-driven culture gives us a competitive advantage.

As of September 28, 2025, we owned and operated 98 Portillo’s restaurants across ten states, including a restaurant owned by C&O Chicago, L.L.C. ("C&O") of which Portillo’s owns 50% of the equity.

Recent Developments and Trends

On September 10, 2025, we announced a strategic reset of our development and growth plans to sharpen focus on our core markets, enhance unit economics, and position the Company for sustained success. The initiatives we announced directly align with these priorities and are anchored by the four goals below:

•Drive transactions by reinforcing value and service.

•Simplify operations, including the discontinuation of our Chicago breakfast pilot.

•Sharpen focus with a more measured pace of new restaurant growth.

•Optimize capital deployment to position Portillo’s for positive free cash flow in 2026.

Additionally, on September 22, 2025, the Company's Board of Directors (the “Board”) announced the departure of Michael Osanloo from his role as President and Chief Executive Officer ("CEO") of the Company, effective September 21, 2025. In the interim, the Board appointed Mike Miles, as CEO of the Company, effective September 21, 2025. Mr. Miles serves as Chairman of the Board, where he has been a member since 2014. As previously disclosed, the Board has initiated a process to identify the Company's next CEO and has hired a global executive search firm to assist in the CEO search processes.

In the quarter and three quarters ended September 28, 2025, total revenue grew 1.8% or $3.2 million and 3.9% or $20.4 million, respectively, primarily due to new restaurant openings in 2024 and 2025. Same-restaurant sales declined 0.8% during the quarter ended September 28, 2025, compared to a 0.9% same-restaurant sales decline during the quarter ended September 29, 2024. Same-restaurant sales increased 0.5% during the three quarters ended September 28, 2025, compared to a 0.9% same-restaurant sales decline during the three quarters ended September 29, 2024. Refer to "Selected Operating Data" section below for definition of Same-Restaurant Sales.

In the quarter and three quarters ended September 28, 2025, commodity inflation was 6.3% and 3.9%, respectively, compared to 3.6% and 5.1% for the quarter and three quarters ended September 29, 2024, respectively. Labor, as a percentage of revenue, net, increased 0.8% and 0.5% during the quarter and three quarters ended September 28, 2025, respectively, compared to the quarter and three quarters ended September 29, 2024, primarily due to lower transactions, incremental wage rate increases, higher benefit costs, and deleverage from our newer restaurant openings, partially offset by a higher average check and labor efficiencies. We increased certain menu prices by approximately 1.5% in January 2025, 1.0% in April 2025, and 0.7% in June 2025.

Development Highlights

During the quarter ended September 28, 2025, we opened four restaurants. Subsequent to September 28, 2025, we opened one additional restaurant, bringing our total restaurant count to 99, as of the filing of this Quarterly Report on Form 10-Q, including a restaurant owned by C&O of which Portillo’s owns 50% of the equity. We plan to open three more restaurants in the fourth quarter, including our first restaurant in Georgia, for a total of 8 new restaurants opened in the fiscal year 2025.

During the third quarter, we opened our first in-line restaurant format. With the exception of the one in-line restaurant, all new restaurant openings in 2025 will be our “Restaurant of the Future” (RoTF 1.0) design, which is a smaller square footage prototype featuring a shorter, more efficient production line designed to reduce cost and provide excellent service to our guests.

Below are the restaurants opened since the beginning of fiscal 2025:

Revenues, Net

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

Revenues for the quarter ended September 28, 2025 were $181.4 million compared to $178.3 million for the quarter ended September 29, 2024, an increase of $3.2 million or 1.8%. The increase in revenues was primarily attributed to the opening of eight restaurants in the third and fourth quarters of 2024 and four restaurants in 2025, partially offset by a decrease in our same-restaurant sales. Restaurants not in our Comparable Restaurant Base (as defined in "Selected Operating Data" below) contributed $5.6 million of the total year-over-year increase. Same-restaurant sales decreased 0.8%, or $1.2 million in the quarter. The same-restaurant sales decline was attributable to a 2.2% decrease in transactions, partially offset by an increase in average check of 1.4%. The higher average check was driven by an approximate 3.2% increase in certain menu prices, partially offset by a 1.8% decrease in product mix. For the purpose of calculating same-restaurant sales for the quarter ended September 28, 2025, sales for 76 restaurants that were open for at least 24 full fiscal periods were included in the Comparable Restaurant Base.

Revenues for the three quarters ended September 28, 2025 were $546.3 million compared to $525.9 million for the three quarters ended September 29, 2024, an increase of $20.4 million or 3.9%. The increase in revenues was primarily attributed to the opening of ten restaurants in 2024 and four restaurants in 2025 and an increase in our same-restaurant sales. Restaurants not in our Comparable Restaurant Base contributed $19.6 million of the total year-over-year increase. Same-restaurant sales increased 0.5%, or $2.5 million. The same-restaurant sales increase was attributable to an increase in average check of 2.7%, partially offset by a 2.2% decrease in transactions. The higher average check was primarily driven by an approximate 3.5% increase in menu prices, partially offset by a 0.8% decrease in product mix. To address inflationary cost pressures, we increased select menu prices by approximately 1.5% in January 2025, 1.0% in April 2025, and 0.7% in June 2025. For the purpose of calculating same-restaurant sales for the three quarters ended September 28, 2025, sales for 76 restaurants that were open for at least 24 full fiscal periods were included in the Comparable Restaurant Base.

The following table summarizes the Company's revenue for the three quarters ended September 28, 2025 and September 29, 2024 (in thousands):

Food, Beverage and Packaging Costs

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

Food, beverage and packaging costs for the quarter ended September 28, 2025 were $62.6 million compared to $60.1 million for the quarter ended September 29, 2024, an increase of $2.5 million or 4.1%. This increase was primarily driven by a 6.3% increase in commodity prices and the opening of eight restaurants during the third and fourth quarters of 2024 and four restaurants in 2025. As a percentage of revenues, net, food, beverage and packaging costs increased 0.8% during the quarter ended September 28, 2025. The increase was primarily due to an increase in certain commodity prices, partially offset by an increase in average check.

General and Administrative Expenses

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

General and administrative expenses for the quarter ended September 28, 2025 were $20.0 million compared to $18.3 million for the quarter ended September 29, 2024, an increase of $1.7 million or 9.4%. This increase was primarily driven by $3.3 million in dead site costs. This increase was partially offset by a $1.1 million net benefit resulting from the CEO transition. This benefit was due to the forfeiture of equity awards, offset by other transition expenses.

General and administrative expenses for the three quarters ended September 28, 2025 were $57.7 million compared to $54.8 million for the three quarters ended September 29, 2024, an increase of $2.9 million or 5.4%. This increase was primarily driven by $3.3 million in dead site cost as well as increases in software license fees related to our enterprise resource planning ("ERP") and human capital management ("HCM") system implementations. This increase was partially offset by a $1.1 million net benefit resulting from the CEO transition. This benefit was due to the forfeiture of equity awards, offset by other transition expenses.

Pre-Opening Expenses

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

Pre-opening expenses for the quarter ended September 28, 2025 were $3.3 million compared to $1.7 million for the quarter ended September 29, 2024, an increase of $1.5 million or 86.6%. The increase was due to the number and timing of activities related to our planned restaurant openings for the quarter ended September 28, 2025 as compared to the quarter ended September 29, 2024.

Pre-opening expenses for the three quarters ended September 28, 2025 were $5.5 million compared to $5.3 million for the three quarters ended September 29, 2024, an increase of $0.2 million or 3.7%. This increase was due to the number and timing of activities related to our planned restaurant openings for the three quarters ended September 28, 2025 as compared to the three quarters ended September 29, 2024.

Depreciation and Amortization

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

Depreciation and amortization expense for the quarter ended September 28, 2025 was $7.3 million compared to $6.7 million for the quarter ended September 29, 2024, an increase of $0.6 million or 9.5%. This increase was primarily attributable to incremental depreciation from capital expenditures related to the opening of eight restaurants in the third and fourth quarters of 2024 and four restaurants in 2025, offset by a reduction in depreciation expense due to fully depreciated assets and disposals compared to the prior year period.

Depreciation and amortization expense for the three quarters ended September 28, 2025 was $21.5 million compared to $20.7 million for the three quarters ended September 29, 2024, an increase of $0.8 million or 3.7%. This increase was primarily attributable to incremental depreciation of capital expenditures related to the opening of ten restaurants in 2024 and four restaurants in 2025, partially offset by a reduction in depreciation expense due to fully depreciated assets and disposals compared to the prior year period.

Net Income Attributable to Equity Method Investment

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

Net income attributable to equity method investment for the quarter ended September 28, 2025 was $0.5 million compared to $0.4 million for the quarter ended September 29, 2024, an increase of $0.07 million or 18.0%. This increase was primarily driven by an increase in sales.

Net income attributable to equity method investment for the three quarters ended September 28, 2025 was $1.0 million compared to $0.9 million for the three quarters ended September 29, 2024, an increase of $0.08 million or 8.1%. This increase was primarily driven by an increase in sales.

Other Loss (Income), Net

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

Other loss (income), net, for the quarter ended September 28, 2025 was a loss of $1.1 million compared to income of $0.4 million for the quarter ended September 29, 2024, a decrease of $1.5 million or 385.1%. This decrease was primarily attributable to a legacy Barnelli's trade name impairment charge and reduced sales tax filing discounts due to the new statutory cap implemented in Illinois on January 1, 2025, partially offset by a settlement received from a service provider regarding their performance.

Other loss (income), net, for the three quarters ended September 28, 2025 was a loss of $0.8 million compared to income of $1.2 million for the three quarters ended September 29, 2024, a decrease of $2.0 million or 168.0%. This decrease was primarily attributable to a legacy Barnelli's trade name impairment charge and reduced sales tax filing discounts due to the new statutory cap implemented in Illinois on January 1, 2025, partially offset by a settlement received from a service provider regarding their performance.

Interest expense for the quarter ended September 28, 2025 was $5.7 million compared to $6.5 million for the quarter ended September 29, 2024, a decrease of $0.8 million or 12.2%. This decrease was primarily driven by a lower effective interest rate attributable to the improved lending terms associated with our 2025 Credit Agreement amendment.

Interest expense for the three quarters ended September 28, 2025 was $17.1 million compared to $19.6 million for the three quarters ended September 29, 2024, a decrease of $2.4 million or 12.5%.

Tax Receivable Agreement Liability Adjustment

We are party to a Tax Receivable Agreement liability with certain members of PHD Group Holdings LLC and its subsidiaries ("Portillo's OpCo”) that provides for the payment by us of 85% of the amount of tax benefits, if any, that Portillo's Inc. actually realizes or in some cases is deemed to realize as a result of certain transactions. On January 24, 2025, we entered into an Amendment to the Tax Receivable Agreement (the "Amendment") with Portillo's OpCo and the TRA Party Representative, as defined in the agreement. The Amendment replaces the LIBOR based interest rate with a Term Secured Overnight Financing Rate ("SOFR") based rate.

The tax receivable agreement liability adjustment for the quarter ended September 28, 2025 was an expense of $0.4 million compared to a benefit of $1.7 million for the quarter ended September 29, 2024. The change was related to a remeasurement primarily due to activity under equity-based compensation plans and impacts from the One Big Beautiful Bill Act (the "Act") which was signed into law on July 4, 2025.

The tax receivable agreement liability adjustment for the three quarters ended September 28, 2025 was a benefit of $2.1 million compared to a benefit of $2.7 million for the three quarters ended September 29, 2024. The change was related to a remeasurement primarily due to activity under equity-based compensation plans and impacts from the Act.

Income Tax (Benefit) Expense

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

Income tax benefit for the quarter ended September 28, 2025 was $1.2 million compared to income tax expense of $2.5 million for the quarter ended September 29, 2024, a decrease of $3.8 million or 149.1%. Our effective income tax rate for the quarter ended September 28, 2025 was 268.2%, compared to 22.4% for the quarter ended September 29, 2024. The increase in our effective income tax rate for the quarter ended September 28, 2025 compared to the quarter ended September 29, 2024 was primarily driven by a decrease in the valuation allowance related to the separation of Mr. Osanloo. This increases the effective income tax rate because the Company recorded a pre-tax loss for the quarter ended September 28, 2025.

Income tax expense for the three quarters ended September 28, 2025 was $3.8 million compared to $4.9 million for the three quarters ended September 29, 2024, a decrease of $1.1 million or 22.6%. Our effective income tax rate for the three quarters ended September 28, 2025 was 20.4%, compared to 17.8% for the three quarters ended September 29, 2024. The increase in our effective income tax rate for the three quarters ended September 28, 2025 compared to the three quarters ended September 29, 2024 was primarily driven by an increase in the Company's ownership interest in Portillo's OpCo, which increases its share of taxable income (loss) of Portillo's OpCo.

Net (Loss) Income Attributable to Non-controlling Interests

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

Net loss attributable to non-controlling interests for the quarter ended September 28, 2025 was $0.4 million, compared to net income attributable to non-controlling interests of $1.6 million for the quarter ended September 29, 2024, a decrease of $2.0 million or 127.8%. The decrease in net income attributable to non-controlling interests for the quarter ended September 28, 2025 was primarily due to a decrease in net income for the quarter ended September 28, 2025 and a decrease in the non-controlling interest holders' weighted average ownership to 4.6% for the quarter ended September 28, 2025 from 15.8% for the quarter ended September 29, 2024.

Net income attributable to non-controlling interests for the three quarters ended September 28, 2025 was $1.6 million, compared to net income attributable to non-controlling interest of $4.4 million for the three quarters ended September 29, 2024, a decrease of $2.8 million or 64.0%. The decrease in net income attributable to non-controlling interests for the three quarters ended September 28, 2025 was primarily due to a decrease in net income and a decrease in the non-controlling interest holders' weighted average ownership to 9.6% for the three quarters ended September 28, 2025 from 17.7% for the three quarters ended September 29, 2024.

Selected Operating Data and Non-GAAP Financial Measures

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

(a) Includes a restaurant that is owned by C&O, of which Portillo’s owns 50% of the equity. AUVs for the quarters ended September 28, 2025 and September 29, 2024 represent AUVs for the twelve months ended September 28, 2025 and September 29, 2024, respectively. Total restaurants indicated are as of September 28, 2025.

(b) Excludes C&O.

(c) For the quarter ended September 29, 2024, same-restaurant sales compares the 13 weeks from July 1, 2024 through September 29, 2024 to the 13 weeks from July 3, 2023 through October 1, 2023. For the three quarters ended September 29, 2024, same-restaurant sales compares the 39 weeks from January 1, 2024 through September 29, 2024 to the 39 weeks from January 2, 2023 through October 1, 2023

Change in Same-Restaurant Sales

The change in same-restaurant sales is the percentage change in year-over-year revenue for the comparable restaurant base, which is defined as the number of restaurants open for at least 24 full fiscal periods (the “Comparable Restaurant Base”). For the three quarters ended September 28, 2025 and September 29, 2024, there were 76 and 70 restaurants in our Comparable Restaurant Base, respectively. The Comparable Restaurant Base excludes C&O.

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")

AUV is the total revenue recognized in the Comparable Restaurant Base, including C&O, divided by the number of restaurants in the Comparable Restaurant Base, including C&O, by period.

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

Non-GAAP Financial Measures

To supplement the condensed 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 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 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, the most directly comparable GAAP measure to Adjusted EBITDA. Adjusted EBITDA Margin represents Adjusted EBITDA as a percentage of revenues, net.

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

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

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

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

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

Liquidity and Capital Resources

Our primary sources of liquidity are cash from operations, cash and cash equivalents on hand, and availability under our 2025 Revolver Facility. As of September 28, 2025, we maintained a cash and cash equivalents and restricted cash balance of $17.2 million and had $68.6 million of availability under our 2025 Revolver Facility, after giving effect to $4.4 million in outstanding letters of credit.

Our primary requirements for liquidity are to fund our working capital needs, operating lease obligations, capital expenditures, and general restaurant support center needs. Our requirements for working capital are not significant because our guests pay for their food and beverage purchases in cash or on debit or credit cards at the time of the sale and we are able to sell many of our inventory items before payment is due to the supplier of such items. Our ongoing capital expenditures are principally related to opening of new restaurants, existing capital investments (both for remodels and maintenance), as well as investments in our restaurant support center infrastructure.

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

Tax Receivable Agreement

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

As of September 28, 2025, we estimate that our obligation for future payments under the TRA totaled $353.2 million. Amounts payable under the TRA are contingent upon, among other things, (i) generation of future taxable income over the term of the TRA and (ii) future changes in tax laws. If we do not generate sufficient taxable income in the aggregate over the term of the TRA to utilize the tax benefits, then we would not be required to make the related TRA payments. The payments that we are required to make will generally reduce the amount of overall cash flow that might have otherwise been available to us, but we expect the cash tax savings we will realize to fund the required payments. Assuming no material changes in relevant tax law and that we earn sufficient taxable income to realize all tax benefits that are subject to the TRA, we estimate that the tax savings associated with all tax attributes described above would aggregate to approximately $415.6 million as of September 28, 2025. Under this scenario, we would be required to pay the TRA Parties approximately 85% of such amount, or $353.2 million,

primarily over the next 15 years, substantially declining in year 16 through year 47. In the three quarters ended September 28, 2025 and September 29, 2024, we made TRA payments of $7.7 million relating to tax year 2023 and $4.4 million relating to tax year 2022, respectively. We expect a payment of $7.8 million relating to tax year 2024 to be paid within the next 12 months.

Summary of Cash Flows

The following table presents a summary of our cash flows from operating, investing and financing activities (in thousands):

			Three Quarters Ended
			September 28, 2025						September 29, 2024
Net cash provided by operating activities			$	48,741					$	71,954
Net cash used in investing activities			(58,079)						(56,437)
Net cash provided by (used in) financing activities			3,696						(7,435)
Net (decrease) increase in cash and cash equivalents and restricted cash			(5,642)						8,082
Cash and cash equivalents and restricted cash at beginning of period			22,876						10,438
Cash and cash equivalents and restricted cash at end of period			$	17,234					$	18,520

Operating Activities

Net cash provided by operating activities for the three quarters ended September 28, 2025 was $48.7 million compared to net cash provided by operating activities of $72.0 million for the three quarters ended September 29, 2024, a decrease of $23.2 million or 32.3%. This decrease was primarily driven by the change in operating assets and liabilities of $13.0 million, a decrease in net income of $7.8 million, and change in non-cash items of $2.4 million.

The $13.0 million change in our operating assets and liabilities balances was primarily driven by operating assets and liabilities being a source of net cash of $4.2 million in the three quarters ended September 28, 2025, compared to a source of net cash of $17.1 million in three quarters ended September 29, 2024 driven by the change in accounts payable and inventory in the three quarters ended September 28, 2025. The decrease in net income for the three quarters ended September 28, 2025 was primarily due to the factors driving the aforementioned change in revenues and expenses as described in the condensed consolidated results of operations in the three quarters ended September 28, 2025 compared to the three quarters ended September 29, 2024. The $2.4 million change from the three quarters ended September 28, 2025 in non-cash charges is primarily driven by lower equity-based compensation expense, partially offset by the asset impairment charge recorded in the third quarter of 2025.

Investing Activities

Net cash used in investing activities was $58.1 million for the three quarters ended September 28, 2025 compared to $56.4 million for the three quarters ended September 29, 2024, an increase of $1.6 million or 2.9%. This increase was primarily due to the number and timing of builds in process.

Financing Activities

Net cash provided by financing activities was $3.7 million for the three quarters ended September 28, 2025 compared to net cash used in financing activities of $7.4 million for the three quarters ended September 29, 2024, an increase of $11.1 million or 149.7%. This increase is primarily due to an increase in proceeds from short-term debt, partially offset by payments of long-term debt in connection with our refinancing in the first quarter of 2025, as described in Note 8. Debt, and an increase of $3.3 million in payments related to the Tax Receivable Agreement liability for the three quarters ended September 28, 2025 as compared to the three quarters ended September 29, 2024.

2025 Revolver Facility and Liens

On January 27, 2025, PHD Intermediate LLC, Portillo’s Holdings LLC, the other Guarantors party thereto, the Lenders from time to time party thereto and Fifth Third Bank, National Association, as Administrative Agent, the L/C Issuer and the Swing Line Lender entered into an amendment (the “Amendment”) to the 2023 Credit Agreement (as amended by the Amendment and as may be amended, restated, supplemented or otherwise modified from time to time thereafter, the “2025 Credit Agreement”).

Portillo's Inc. Form 10-Q | 35

Table of Contents

The Amendment provides for, among other things, (i) a $250 million term loan A facility (the “2025 Term Loan”) and (ii) revolving credit commitments in an initial aggregate principal amount of $150 million (the “2025 Revolver Facility” and, together with the Term Loan Facility, the “2025 Facilities”), the proceeds of which will be used to refinance indebtedness under the 2023 Credit Agreement, for general corporate purposes and working capital needs and for other activities permitted under the 2025 Credit Agreement. The loans under each of the 2025 Facilities mature on January 27, 2030.

As of September 28, 2025, we had $77.0 million of borrowings under the 2025 Revolver Facility, and letters of credit issued under the 2025 Revolver Facility totaled $4.4 million. As a result, as of September 28, 2025, the Company had $68.6 million available under the 2025 Revolver Facility.

The 2025 Credit Agreement contains customary representations and warranties, events of default, reporting and other affirmative covenants and negative covenants, including limitations on indebtedness, liens, investments, negative pledges, dividends, junior financings and other fundamental changes. As of September 28, 2025, the Company was in compliance with financial covenants in the 2025 Credit Agreement.

Critical Accounting Estimates

This discussion and analysis of financial condition and results of operations is based upon the Company's condensed consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of these financial statements requires the Company to make estimates, judgments, and assumptions that can have a meaningful effect on the reporting of condensed consolidated financial statements. There have been no significant changes to our critical accounting estimates or significant accounting policies as disclosed in our Annual Report on Form 10-K for the fiscal year ended December 29, 2024, except as set forth below.

Goodwill and Indefinite-Lived Intangible Assets

Goodwill and indefinite-lived intangible assets are assessed for impairment annually or more frequently if events and circumstances indicate that it is more likely than not that the fair value of a reporting unit or an intangible asset is less than its carrying value.

In the quarter ended September 28, 2025, management identified impairment indicators that required a quantitative assessment of goodwill and trade names outside of the Company's annual impairment test. Refer to Note 2. Summary Of Significant Accounting Policies for a discussion of the impairment indicators identified during the period.

The Company has one reporting unit and during fiscal 2025, the Company refined its methodology for estimating the fair value of its reporting unit. In prior periods, the Company primarily utilized a market capitalization approach. Beginning in fiscal 2025, the Company incorporated a weighted combination of the income and market approaches to estimate fair value. Management believes this change provides a more comprehensive and representative valuation of the reporting unit by considering both the Company’s projected future cash flows and observable market data for comparable companies.

Under the income approach, the Company uses a discounted cash flow methodology, which requires management to make significant estimates and assumptions related to forecasted revenues, EBITDA margins, capital expenditures, perpetual growth rates, and long-term discount rates, among others. The market approach incorporated both the guideline public company method and the guideline transaction method. The guideline public company method involves analyzing valuation multiples of comparable publicly traded companies with similar operating and investment characteristics, while the guideline transaction method considers transaction multiples observed for comparable businesses. The Company also reconciles the fair value of its reporting unit to its current market capitalization to assess reasonableness. If the fair value of the reporting unit is less than its carrying value, an impairment loss is recorded for the difference between the fair value of the reporting unit and the carrying value of the reporting unit. Upon completion of the quantitative impairment test and review of the related results in connection with the preparation of this Quarterly Report on Form 10-Q, the Company determined that the fair value of the reporting unit exceeded its carrying value by approximately 19%. Accordingly, the Company concluded that no impairment of goodwill existed as of the

Portillo's Inc. Form 10-Q | 36

Table of Contents

quarter and three quarters ended September 28, 2025.

The Company’s indefinite-lived intangible assets consist of trade names and trademarks (collectively “trade names”). The Company estimates the fair value of its trade names using a relief-from-royalty income approach. If the fair value of the trade name is less than its carrying value, an impairment loss is recorded for the difference between the estimated fair value and carrying value of the intangible assets. After completing the quantitative impairment test in connection with the preparation of this Quarterly Report on Form 10-Q, the Company recorded a non-cash impairment charge of $2.2 million to its legacy Barnelli's trade name, a pasta concept available at nine co-branded restaurants, during the quarter and three quarters ended September 28, 2025. This impairment charge is included within other loss (income), net in the condensed consolidated statements of operations.

Significant changes in economic and market conditions could result in changes to expectations of future financial results and key valuation assumptions. Such changes could result in revisions of our estimates of the fair value of our reporting unit and could result in an impairment of goodwill or intangibles in a future interim period or as of September 29, 2025, our next annual measurement date. As of September 28, 2025, we had approximately $394.3 million of goodwill and $221.7 million of indefinite-lived intangible assets.
