NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and include the accounts of the Company and its subsidiaries. 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 consolidated financial statements, and therefore, does not separately present a statement of comprehensive income (loss).

Fiscal Year

The Company operates on a 52- or 53-week fiscal year ending on the Sunday on or prior to December 31. In a 52-week fiscal year, each quarterly period is comprised of 13 weeks. The additional week in a 53-week fiscal year is added to the fourth quarter. Fiscal 2025 and 2024 each consisted of 52 weeks. Fiscal 2023 consisted of 53 weeks. The 53rd week in fiscal 2023 coincided with Christmas, resulting in six additional operating days. The fiscal periods presented in this report are fiscal years ended December 28, 2025 ("fiscal 2025"), December 29, 2024 ("fiscal 2024") and December 31, 2023 ("fiscal 2023"), respectively. Unless otherwise stated, references to years in this report relate to fiscal years.

Use of Estimates

The preparation of these 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.

Cash and Cash Equivalents and Restricted Cash

Cash includes amounts that are either held in the Company’s bank accounts or represent deposits in transit. Amounts receivable from credit card processors are considered cash equivalents because they are both short in term and highly liquid in nature and are typically converted to cash within three business days of the sales transactions.

Restricted cash includes amounts that are held in the Company’s bank accounts subject to minimum balance requirements for medical claim disbursements.

Accounts and Tenant Improvement Receivables

Accounts and tenant improvement receivables consist primarily of vendor rebates, tenant improvement receivables, and delivery receivables as well as receivables from related parties (Note 18. Related Party Transactions). The Company evaluates the collectability of its Accounts and tenant improvement receivables based on a variety of factors, including historical experience, current and future economic and market conditions and other factors. Based on these factors, no allowance for uncollectible accounts was recorded at December 28, 2025 or December 29, 2024.

Inventories

Inventories, which consists mainly of food products, is valued at the lower of cost or net realizable value, with cost determined on the first-in, first-out (FIFO) method. No other adjustment is deemed necessary to reduce inventory to lower of cost or net realizable value due to the rapid turnover and high utilization of inventory.

The Company operatestwo commissaries to supply the Company's restaurants with several products and ensures product consistency and quality. The commissaries derive revenue principally from the sale and distribution of food to our distributors, who, in turn, sell the food to the restaurants. This is considered under ASC 845, Non-Monetary Transactions, and the impact on the statement of operations is not material. These products are held as inventory at distributors on a short-term consignment basis. Inventories subject to these consignment arrangements are recorded on the Company’s consolidated balance sheet and were $0.8 million as of December 28, 2025 and December 29, 2024.

Equity Method Investment

The Company has a 50% interest in C&O. The Company accounts for the investment and financial results in the consolidated financial statements under the equity method of accounting as the Company has significant influence but does not have control. The investment is adjusted to reflect the Company’s share of C&O’s earnings and losses to date and any distributions received.

Long-Lived Assets and Valuation

The Company’s long-lived assets include property and equipment and definite-lived intangible assets. Property and equipment are recorded at cost. Internal costs directly associated with the acquisition, development and construction of a restaurant are capitalized. Expenditures for refurbishments and improvements that significantly add to the productivity capacity or extend the useful life are capitalized, while expenditures for maintenance and repairs are expensed as incurred. Leasehold improvements are amortized over the shorter of the lease term, which generally includes option periods that are reasonably certain, or the estimated useful lives of the assets. For buildings and equipment, depreciation is computed over the estimated useful lives of the assets (generally ranging from three to 39 years). Upon disposal of assets, the accounts are relieved of cost and accumulated depreciation and any related gain or loss is reflected in other income, net in the Company's consolidated statements of operations.

The Company reviews its long-lived assets, including property and equipment and construction-in-progress, definite-lived intangible assets and operating lease assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group might not be recoverable. Recoverability is measured by a comparison of the carrying amount to future undiscounted cash flows that are expected to be generated by the asset or asset group. If the carrying amount exceeds its estimated future cash flows, an impairment charge is recognized in the amount by which the carrying value exceeds the estimated fair value. Restaurant-level assets are grouped by restaurant for the purpose of the impairment assessment because a restaurant represents the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. During fiscal 2024, the Company recorded a technology asset impairment charge of $0.7 million that was included within other income, net in the Company's consolidated statements of operations. There wereno long-lived asset impairment charges recorded in fiscal 2025 and fiscal 2023.

Goodwill and Indefinite-Lived Intangible Assets

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.

The Company hasone 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.

In the third quarter of 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. Upon completion of the quantitative impairment test and review of the related results, the Company concluded thatno impairment of goodwill existed. The Company's annual impairment test in the fourth quarter of 2025 reaffirmed that goodwill was not impaired.

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.

The Company also tested its trade names for impairment in the third quarter of 2025. As a result, during fiscal 2025, 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.

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 28, 2026, our next annual measurement date. As of December 28, 2025, we had approximately $394.3 million of goodwill and $221.7 million of indefinite-lived intangible assets.

There wereno goodwill nor indefinite-lived intangible asset impairment charges recorded in fiscal 2024 and fiscal 2023.

Fair Value of Financial Instruments

The Company discloses and recognizes the fair value of its assets and liabilities using a hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. The guidance establishes three levels of the fair value hierarchy as follows:

Level 1 - Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date;

Level 2 - Inputs are observable, unadjusted quoted prices in active markets for similar assets or liabilities, unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the related assets or liabilities; and

Level 3 - Unobservable inputs that are significant to the measurement of the fair value of the assets or liabilities that are supported by little or no market data.

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.

The Company also offers delivery services to its customers. 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.

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). During the fourth quarter of 2025, the Company completed its annual assessment of expected gift card breakage based on historical redemption patterns to determine the amount of gift card sales that will not be redeemed and will be retained by the Company. As a result of this analysis, the estimated breakage rate was updated to 12%, compared to the prior rate of 11%. This update represents a change in accounting estimate and has been applied prospectively. Gift card breakage is recognized within revenues, net in the consolidated statements of operations.

In March 2025, the Company launched Portillo's Perks TM, 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. 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. Refer to Note 3. Revenue Recognition for additional detail on the Perks liability.

Generally, revenue is recognized as promised goods or services transfer to the guest or customer in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. Revenues are recognized when payment is tendered at the point of sale as the performance obligation has been satisfied. Refer to Note 3. Revenue Recognition for additional detail.

Contingencies

We recognize liabilities for contingencies when we have an exposure that indicates it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Our ultimate legal and financial liability with respect to such matters cannot be estimated with certainty and requires the use of estimates. When the reasonable estimate is a range, the recorded loss will be the best estimate within the range. We record legal settlement costs when those costs are probable and reasonably estimable. Refer to Note 16. Contingencies for additional detail.

Commitments

The majority of the food products the Company purchases are subject to changes in price primarily due to the effect of supply and demand of the commodities, in particular, proteins, dairy, produce and grains. Overall pricing agreements are established in an effort to maintain a more consistent food cost without creating long-term purchase commitments.

Employee Benefits

The Company sponsors a 401(k) plan for all employees that are eligible based upon age and length of service. The expenses incurred for Company matching contributions to the plan were approximately $0.7 million, $0.6 million and $0.4 million for the years ended December 28, 2025, December 29, 2024 and December 31, 2023, respectively.

The Company offers a non-qualified deferred compensation plan to certain officers and other members of management. Under the plan, eligible employees may defer up to 80% of their annual salary and annual bonus. The Company has elected to fund its deferred compensation obligations through a rabbi trust. The rabbi trust is subject to creditor claims in the event of insolvency, but such assets are not available for general corporate purposes. Assets held in the rabbi trust are invested in mutual funds, which are purchased and held principally for the purpose of selling them in the near term, and are classified as trading securities and carried at fair value.

Equity-Based Compensation

The Company has issued non-qualified stock options, performance-based stock options, performance stock units, restricted stock units and restricted stock awards. Equity-based compensation expense is generally measured based on the grant-date fair value of those awards and is recognized on a straight-line basis over the vesting period. Equity-based compensation expense is based on awards ultimately expected to vest and is reduced for estimated forfeitures. Forfeitures are revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates and an adjustment to equity-based compensation expense will be recognized at that time. We have also granted equity awards with performance vesting conditions. Equity awards with performance or market vesting conditions generally vest based on our attainment versus stated targets or criteria over athree-year performance and service period. Performance goals are determined by the Board and include measures such as revenue and adjusted EBITDA growth. Compensation expense on stock awards subject to performance conditions, which is based on the quantity of awards we have determined are probable of vesting, is recognized over the longer of the estimated performance goal attainment period or time vesting period. Equity-based compensation expense is included within general and administrative expenses and labor in the consolidated statements of operations. Refer to Note 13. Equity-Based Compensation for additional detail.

The Company adopted an Employee Share Purchase Plan (“ESPP”) in June 2022 under which qualifying employees may be granted purchase rights to the Company’s common shares at not less than 85% of the market price on the purchase date, subject to Company discretion. The ESPP has a maximum of 250,000 shares of the Company's Class A common stock available for issuance. Eligible employees are able to contribute up to 15% of their gross base earnings for purchases under the ESPP through regular payroll deductions, subject to an annual maximum dollar amount. The expense incurred under the ESPP for the year ended December 28, 2025 was $0.1 million, andimmaterial for the years ended December 29, 2024 and December 31, 2023. The expense is included within general and administrative expenses and labor in the consolidated statement of operations.

Advertising and Marketing Expenses

Advertising costs are expensed the first-time advertising takes place, while the costs of producing advertising are expensed during production and the costs of communicating advertising are expensed as services are received. Advertising and marketing expenses totaled $9.4 million, $8.0 million and $5.9 million for the years ended December 28, 2025, December 29, 2024 and December 31, 2023, respectively. Advertising and marketing expenses included in other operating expenses in the consolidated statements of operations primarily relate to sponsorships, restaurant merchandising and charitable giving; and those expenses included in general and administrative expenses in the consolidated statements of operations primarily consist of regional advertising and branding initiatives.

Cloud-Based Software Implementation Costs

The Company has entered into cloud-based software hosting arrangements for which it incurs implementation costs. Certain costs incurred during the application development stage are capitalized and included within prepaid expenses or other assets, depending on the long or short-term nature of such costs, in line with the Company's policy on the accounting for prepaid software hosting arrangements. Costs incurred during the preliminary project stage and post-implementation stage are expensed as incurred. Capitalized cloud-based software implementation costs are amortized, beginning on the date the related software or module is ready for its intended use, on a straight-line basis over the remaining term of the hosting arrangement as a component of general and administrative expenses, the same line item as the expense for the associated hosting arrangement.

As of December 28, 2025, the Company had $3.2 million of capitalized cloud-based software implementation costs made up of $1.0 million recorded within prepaid expenses and other and $2.2 million recorded within other assets. As of December 29, 2024, the Company had $3.4 million of capitalized cloud-based software implementation costs made up of $0.9 million recorded within prepaid expenses and other and $2.5 million recorded within other assets. The capitalized cloud-based costs primarily relate to the Company's enterprise resource planning ("ERP") and human capital management ("HCM") systems.

Leases

The Company currently leases land for its retail restaurants and commissaries, and office space under various long-term operating lease agreements that expire on various dates through 2068. We also lease equipment, which primarily consists of restaurant equipment and copiers. We have immaterial short-term operating leases, such as those for seasonal rentals and training spaces. We evaluate the contracts to determine whether the contract involves the use of property or equipment, which is either explicitly or implicitly identified. We evaluate whether we control the use of the asset, which is determined by assessing whether we obtain substantially all economic benefits from the use of the asset, and whether we have the right to direct the use of the asset. If these criteria are met and we have identified a lease, we account for the contract under the requirements of ASC 842.

Upon the possession of a leased asset, we determine its classification as an operating or finance lease. As of December 28, 2025, all of our leases are classified as operating leases. Operating lease assets and liabilities are recognized at the lease commencement date. We make judgments regarding the probable term for each lease, which can impact the classification and accounting for a lease as operating or financing, as well as the amount of straight-line rent expense in a particular period. Generally, the leases for the Company's restaurant locations have an initial term of 10 years to 20 years and typically provide for renewal options infive-year increments, as well as rent escalations. Renewal options are generally recognized as part of the right-of-use assets and lease liabilities as it is reasonably certain at commencement date that we would exercise the options to extend the lease. Some of our real estate leases provide for base rent, plus if applicable, additional rent based on gross sales, as defined in each lease agreement, which is considered to be variable rent. When the achievement of such sales thresholds are deemed to be probable, contingent rent is accrued in proportion to the sales recognized during the period. For operating leases that include rent holidays and rent escalation clauses, we recognize lease expense on a straight-line basis over the lease term from the date we take possession of the leased property. Lease expense incurred before a restaurant opens is recorded in pre-opening expenses in the consolidated statements of operations. Once a restaurant opens, we record the straight-line lease expense and any contingent rent, if applicable, in occupancy on the consolidated statements of operations. Many of our leases also require us to pay real estate taxes, common area maintenance costs and other occupancy costs which are included in occupancy, other operating expenses, or pre-opening expenses on the consolidated statements of operations, which are generally considered to be variable rent. For leases with a lease term of 12 months or less ("short-term operating lease"), any fixed lease payments are recognized on a straight-line basis over such term, and are not recognized on the consolidated balance sheets.

Per the ASC 842 requirements, a lessee is required to use the rate implicit in the lease when readily determinable; alternatively, it would use the incremental borrowing rate in determining the present value of future lease payments. We estimate our incremental borrowing rates corresponding to the maturities of our leases. We estimate this rate based on prevailing financial market conditions, indications for the Company's credit rating, and other benchmarks related to the Company's outstanding secured borrowings.

We expend cash for leasehold improvements to build out our leased premises. Generally, a portion of the leasehold improvements and building costs are reimbursed by our landlords as landlord incentives pursuant to agreed-upon terms in our lease agreements. If obtained, landlord incentives usually take the form of cash, full or partial credits against our future minimum or contingent rents otherwise payable by us, or a combination thereof. In most cases, the tenant improvement allowances are received after we take possession of the property, as we meet required milestones during the construction of the property. We include these amounts in the measurement of the initial operating lease liability, which are also reflected as a reduction to the initial measurement of the right-of-use asset.

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 of the restaurant facility and the restaurant opening date, travel for the opening team, food, beverage, and the initial stocking of operating supplies. These are expensed as incurred prior to the restaurant opening for business.

Self-Insurance Programs

The Company self-insures for health, workers’ compensation, general liability and property damage. Predetermined loss limits have been arranged with insurance companies to limit the Company’s per occurrence cash outlay. Estimated costs to settle reported claims and incurred but unreported claims are recorded in in accrued expenses in the consolidated balance sheets.

Income and Other Taxes

We account for income taxes pursuant to the asset and liability method which requires the recognition of deferred income tax assets and liabilities related to the expected future tax consequences arising from temporary differences between the carrying amounts and tax bases of assets and liabilities based on enacted statutory tax rates applicable to the periods in which the temporary differences are expected to reverse. Any effects of changes in income tax rates or laws are included in income tax expense in the period of enactment. A valuation allowance is recognized if we determine it is more likely than not that all or a portion of a deferred tax asset will not be recognized. In making such determination, the Company considers all available evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, prudent and feasible tax planning strategies and recent and expected future results of operations. The assumptions utilized in determining future taxable income require significant judgment and are consistent with the plans and estimates we use to manage our business. Actual operating results in future years could differ from our current assumptions, judgments and estimates, which could have a material impact on the amount of deferred tax assets we ultimately realize.

The Company is party to a Tax Receivable Agreement ("TRA") with certain pre-IPO LLC Members that provides for the payment by the Company 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. We account for the TRA liability in accordance with ASC 450 -Contingencies. 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. Therefore, we would only recognize a liability for TRA payments if we determine it is probable that we will generate sufficient future taxable income over the term of the TRA to utilize the related tax benefits. The timing and amount of aggregate payments due under the TRA may vary based on a number of factors, including the amount and timing of taxable income generated by Portillo's OpCo each year and the applicable tax rates.

The amounts recorded for both the deferred tax assets and the liability for the Company's obligations under the TRA will be estimated at the time of any purchase or exchange as a reduction to stockholders' equity, and the effects of changes in any of the Company's estimates after this date will be included in net income or loss. Similarly, the effect of subsequent changes in the enacted tax rates will be included in net income or loss.

Earnings (Loss) Per Share

Basic earnings (loss) per share is calculated by dividing the net income (loss) attributable to common shareholders by the weighted-average number of shares outstanding.

Diluted earnings (loss) per share adjusts the basic earnings (loss) per unit attributable to shareholders and the weighted-average number of units of shares outstanding for the potential dilutive impact of shares, using the treasury-stock method. Diluted earnings (loss) per share considers the impact of potentially dilutive securities except in periods in which there is a loss because the inclusion of the potential common units would have an anti-dilutive effect.

Recently Issued Accounting Standards

In October 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative, which amends the disclosure or presentation requirements related to various subtopics in the FASB Accounting Standards Codification (the “Codification”). The effective date for each amendment will be the date on which the SEC’s removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective, with early adoption prohibited.

NOTE 13. EQUITY-BASED COMPENSATION

2021 Equity Incentive Plan

In connection with the IPO, the Company adopted the 2021 Equity Incentive Plan (the "2021 Plan"). The 2021 Plan is administered and interpreted by the Company's Board, including the authority to select participants in the 2021 Plan, determine the form and substance of awards under the 2021 Plan, determine the conditions and restrictions, if any, subject to which such awards will be made, modify the terms of awards, accelerate the vesting of awards, and make determinations regarding a participant’s termination of employment or service for purposes of an award. The types of awards available under the 2021 Plan include stock options (both incentive and non-qualified), stock appreciation rights ("SARs"), restricted stock awards ("RSAs"), restricted stock units ("RSUs"), and stock-based awards. Employees, officers, non-employee directors or any natural person who is a consultant or other personal service provider to the Company or any of its subsidiaries or affiliates are eligible to participate in the 2021 Plan. All awards granted to participants under the 2021 Plan will be represented by an award agreement. Approximately 7.1 million shares of Class A common stock were authorized for awards under the 2021 Plan.

Restricted Stock Units

An RSU granted under the 2021 Plan will give the participant a right to receive, upon vesting and settlement of the RSUs, one share per vested unit or an amount per vested unit equal to the fair market value of one share as of the date of determination. The fair value of RSUs is determined using the Company's closing stock price on the date of grant. Outstanding time-based RSUs generally vest equally over periods ranging fromone tothree years on each of the anniversaries of the date of grant subject to continued service on such date.

Activity for the Company's RSUs was as follows:

As of December 28, 2025, there was $10.8 million of total unrecognized compensation cost related to unvested restricted stock units, which is expected to vest over a weighted-average period of 1.8 years.

Performance Stock Options

The Company has granted performance stock options ("PSOs") to certain executive officers that will be eligible to vest inthree (3) tranches based on stock performance conditions (i) one-third (1/3rd) of the PSOs will vest on the third anniversary of the IPO if the 20-day volume-weighted average price ("VWAP") for a share of common stock is $30.00 per share (1.5 times the IPO price) measured over any twenty (20) consecutive trading day period commencing on the second anniversary of the IPO and ending on the last trading day immediately preceding the third anniversary of the IPO; (ii) one-third (1/3rd) of the PSOs will vest on the fourth anniversary of the IPO if the 20-day VWAP for a share of common stock is $40.00 per share (2 times the IPO price) measured over any twenty (20) consecutive trading day period commencing on the third anniversary of the IPO and ending on the last trading day immediately preceding the fourth anniversary of the IPO; and (iii) one-third (1/3rd) of the PSOs will vest on the fifth anniversary of the IPO if the 20-day VWAP for a share of common stock is $50.00 per share (2.5 times the IPO price) measured over any twenty (20) consecutive trading day period commencing on the fourth anniversary of the IPO and ending on the last trading day immediately preceding the fifth anniversary of IPO. All PSOs are subject to continued service at each tranche date and if any tranches fail to vest, the unvested portion of such PSOs will be forfeited and will not be eligible to vest in subsequent years. The awards granted are exercisable within a 10-year period from the date of grant. The first and second tranches of PSOs were forfeited in fiscal 2024 and fiscal 2025, respectively, as the performance conditions were not satisfied by the third and fourth anniversary of the IPO, respectively.

The grant date fair value of these awards was determined using a Monte-Carlo simulation model. The fair value and weighted average assumptions used to estimate the fair value of these PSOs were as follows:

Activity for the Company's PSOs was as follows:

As of December 28, 2025, there was $0.2 million of total unrecognized compensation cost related to unvested PSOs, which is expected to be recognized over a weighted average period of 0.8 years.

Stock Options

The stock options vest on thefourth anniversary of the award and are exercisable within a 10-year period from the date of grant. Stock options under the 2021 Plan were granted to the Company's former Chief Executive Officer ("CEO"), Mr. Osanloo, who departed from his role, effective September 21, 2025.

Activity for the Stock Options was as follows:

The Company estimates the fair value of stock options on the date of grant using the Black-Scholes option-pricing model. The Black-Scholes option-pricing model requires estimates of highly subjective assumptions, which greatly affect the fair value of each stock option. The assumptions used to estimate the fair value of stock options granted during the year ended December 28, 2025 were as follows:

As of December 28, 2025, there wasno unrecognized compensation cost related to unvested Stock Options.

Performance Stock Units

The Company has granted performance stock units ("PSUs") to its executive officers under the 2021 Plan. The fair value of these awards was determined using the Company's closing stock price on the date of the grants. The PSUs will vest after the fiscal year ending December 26, 2027, and December 27, 2026, for PSUs granted during the years ended December 28, 2025 and December 29, 2024, respectively, 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 over the fiscal years 2025 to 2027 for PSUs granted during the year ended December 28, 2025 and over the fiscal years 2024 to 2026 for PSUs granted during the year ending December 29, 2024. Compensation expense related to the performance equity units is recognized using a straight-line method over the vesting period based on the most probable outcome of the performance conditions. 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. As of December 28, 2025, management calculated an attainment rate for both PSUs granted during the year ended December 28, 2025 and December 29, 2024 equal to 0% of the number of target shares granted based on actual attainment of the internal metrics.

Activity for the Company's PSUs was as follows:

*The expected to vest total above represents outstanding base PSUs, adjusted for expected attainment amounts in line with current and future estimated performance levels as described above.

As of December 28, 2025, there wasno unrecognized compensation cost related to unvested PSUs based on the aforementioned attainment rate, the PSUs have a weighted average remaining period of 1.4 years.

2014 Equity Incentive Plan

Prior to the IPO, the Company had granted stock options under its 2014 Equity Incentive Plan, as amended (the “2014 Plan”). The 2014 Plan permitted the granting of awards to employees, officers, directors and consultants of the Company and affiliates in the form of options, unit appreciation rights, Restricted Class A Units, unrestricted Class A Units, Performance Awards and awards convertible into or otherwise based on Class A Units. Prior to the IPO, the 2014 Plan gave broad powers to the Company’s board of managers for its administration and interpretation, including the authority to select the individuals to be granted awards and rights to prescribe the particular form and conditions of each award to be granted. Under the 2014 Plan, the number of shares and exercise price of each option were determined by the board of managers, or a committee designated by the board of managers. The awards granted were generally exercisable within a 10-year period from the date of grant.

The unit option grants were equally divided between (i) options subject to time-based vesting, and (ii) options subject to both time-based and performance-based vesting. The time-based vesting options vest, in general, in equal annual installments over a 5-year period and have a 10-year term from the date of the grant. The options subject to both time-based and performance-based vesting have aten-year term from the date of the grant and vest, in general, in equal annual installments over a 5-year period from the date of grant, subject to acceleration in the event of a sale transaction, and have a performance condition that is satisfied upon achievement of a specified internal rate of return and a minimum multiple of invested capital. In connection with the IPO, the performance condition was waived and all such options became subject to time-based vesting only.

Following the IPO, no further options will be granted under the 2014 Plan.

Activity under the 2014 Plan was as follows:

As of December 28, 2025, there was $0.1 million of total unrecognized compensation cost related to unvested options under the 2014 plan, which is expected to be recognized over a weighted average period of 0.3 years.

Equity-Based Compensation Expense

Equity-based compensation expense is calculated based on equity awards ultimately expected to vest and is reduced for estimated forfeitures. Forfeitures are revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates and an adjustment to equity-based compensation expense will be recognized at that time.

Equity-based compensation expense included in the Company’s consolidated statements of operations was as follows (in thousands):

In connection with the aforementioned departure of the Company's CEO, Mr. Osanloo and the Company entered into a Separation Agreement and Release (the “Separation Agreement”). In accordance with the Separation Agreement, Mr. Osanloo's outstanding stock option awards granted to him on October 1, 2018 under the 2014 Equity Incentive Plan will remain exercisable through the 10 th anniversary of the original grant date. The modification was to extend the permitted time for which the options could be exercised subsequent to termination, from 90 days to October 1, 2028. The Company recorded a $2.4 million charge to equity-based compensation expense during fiscal 2025, to reflect the incremental value related to the modification described herein. The incremental modification expense is included within general and administrative expenses in the consolidated statement of operations. All other equity grants were forfeited, resulting in a credit of previously-recognized equity-based compensation expense of $5.0 million.

NOTE 14. 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 components of income tax expense are as follows (in thousands):

Reconciliations of income tax expense computed at the U.S. federal statutory income tax rate to the recognized income tax expense and the U.S. statutory income tax rate to our effective tax rates are as follows (in thousands):

(1) State taxes in Illinois made up the majority (greater than 50 percent) of the tax effect in this category.

Our effective income tax rates for the years ended December 28, 2025, December 29, 2024 and December 31, 2023 were 12.4%,16.2% and 11.5%, respectively. The decrease in our effective income tax rate from the year ended December 28, 2025 to the year ended December 29, 2024 was primarily driven by a decrease in the valuation allowance related to the separation of Mr. Osanloo and year-over-year impact of deferred tax asset remeasurement due to effective state tax rate changes, partially offset 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 for the year ended December 28, 2025, December 29, 2024 and December 31, 2023 differs from the statutory rate of 21% primarily because the Company is not liable for income taxes on the portion of OpCo’s earnings that are attributable to non-controlling interests, deferred tax adjustments, impacts from equity-based award activity and the change in valuation allowance.

Deferred Tax Assets

The components of deferred tax assets and liabilities are as follows (in thousands):

As described in Note 11. Stockholders' Equity, we acquired LLC Units in connection with the IPO and Transactions and Secondary Offerings. During the years ended December 28, 2025 and December 29, 2024, we recognized a deferred tax asset in the amount of $41.5 million and $63.9 million, respectively, associated with the basis difference in our investment in Portillo's OpCo from acquiring these LLC Units.

During the years ended December 28, 2025 and December 29, 2024, we also recognized deferred tax assets in the amount of $86.6 million and $78.5 million, respectively, related to additional tax basis increases generated from expected future payments under the TRA and related deductions for imputed interest on such payments.

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. During the years ended December 28, 2025 and December 29, 2024, the Company recognized deferred tax assets of $41.5 million and $63.9 million, respectively, associated with the basis difference in its investment in Portillo's OpCo from acquiring these LLC Units. However, a portion of the total basis difference will 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. As of December 28, 2025 and December 29, 2024, the Company recorded a valuation allowance in the amount of $7.0 million and $7.2 million, respectively, against the deferred tax asset.

As of December 28, 2025 and December 29, 2024, the Company had federal and state net operating loss carry forwards of $74.4 million and $47.0 million, respectively, available to reduce future taxable income, if any. Federal losses that arose prior to 2018 will begin to expire in 2034. Federal losses generated after 2017 will be carried forward indefinitely. The majority of state losses will begin to expire in 2034 and future periods.

As of December 28, 2025 and December 29, 2024, the Company had interest limitation carry forwards of $15.0 million and $14.6 million, respectively, as a result of the Company's ownership interest in Portillo's OpCo.

Unrecognized Tax Benefits

The Company recordedno unrecognized tax benefits as of December 28, 2025 and December 29, 2024. Portillo's Inc. was formed in June 2021 and did not engage in any operations prior to the IPO and Transactions. Portillo's has filed all income tax returns for tax years through

2024. These returns are subject to examination by taxing authorities for U.S. federal and state income tax purposes. Additionally, although Portillo's OpCo is treated as a partnership for U.S. federal and state income taxes purposes, it is still required to file an annual U.S. Return of Partnership Income, which is subject to examination by the Internal Revenue Service ("IRS"). As of December 28, 2025, there are no ongoing U.S. federal, state or local income tax return examinations.

Pursuant to the Company's election under section 754 of the Internal Revenue Code (the "Code"), the Company expects to obtain an increase in its share of the tax basis in the net assets of Portillo's OpCo when LLC Units are exchanged by other members. The Company intends to treat any exchanges of LLC Units as direct purchases of LLC Units for U.S. federal income tax purposes. These increases in tax basis may reduce the amounts that would otherwise be paid in the future to the U.S. federal, state and local authorities. These increases may also decrease gains (or increase losses) on future dispositions of certain assets to the extent tax basis is allocated to those assets.

In the second quarter of 2025, in connection with the pre-IPO LLC Members unit redemption previously discussed in Note 11. Stockholders' Equity,7,290,465 LLC Units were redeemed for newly-issued shares of Class A common stock. As a result, an increase in the tax basis of net assets of Portillo's OpCo subject to the provisions of the TRA was recorded. The Company recorded a deferred tax asset of $16.8 million and an additional TRA liability of $38.5 million.

In 2024, in connection with the pre-IPO LLC Members unit redemption previously discussed in Note 11. Stockholders' Equity,840,992 LLC Units were redeemed for newly-issued shares of Class A common stock. As a result, an increase in the tax basis of net assets of Portillo's OpCo subject to the provisions of the TRA was recorded. The Company recorded a deferred tax asset of $1.7 million and an additional TRA liability of $4.3 million.

In 2024, in connection with the Q1 2024 Secondary Offering previously discussed in Note 11. Stockholders' Equity,5,832,371 LLC Units were redeemed by the pre-IPO LLC Members for newly-issued shares of Class A common stock. As a result, an increase in the tax basis of net assets of Portillo's OpCo subject to the provisions of the TRA was recorded. The Company recorded a deferred tax asset of $17.8 million and an additional TRA liability of $33.7 million.

As of December 28, 2025, we estimate that our obligation for future payments under the TRA totaled $352.4 million. The Company made payments of $7.7 million under the TRA during the year ended December 28, 2025 relating to tax year 2023 and we expect a payment of $7.9 million relating to tax year 2024 to be made within the next 12 months. Refer to Note 2. Summary Of Significant Accounting Policies for additional information on the TRA.

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 provision 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 other 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 15. 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 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 years ended December 28, 2025, December 29, 2024 and December 31, 2023 are as follows (in thousands):

Shares of the Company’s Class B Common Stock do not participate in the earnings or losses of Portillo's Inc. and are therefore not participating securities. As such, separate presentation of basic and diluted earnings per share of Class B Common Stock under the two-class method has not been presented.

The following outstanding shares were excluded from the calculation of diluted earnings per share because they would be antidilutive or subject to performance conditions which have not been satisfied by the end of the reporting period (in thousands):

NOTE 16. 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. We maintain insurance coverage with third-party insurers to limit our total exposure. The likelihood of loss for these legal proceedings, based on definitions within contingency accounting literature, ranges from remote to reasonably possible to probable. When probable and reasonably estimable, the losses are accrued. Although the ultimate outcome of these claims and lawsuits cannot be predicted with certainty, management believes that the resulting liability, if any, will not have a material effect on the Company’s consolidated financial statements.

During 2024, a former team member fromone of the Company'stwo 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”). As of December 28, 2025, a $0.8 million litigation reserve has been recorded in accounts payable on our consolidated balance sheet.

On August 19, 2025, plaintiffs filed a wrongful death and survival action in Cook County, Illinois, arising out of a vehicle accident that occurred at a Portillo’s location in Oswego, Illinois. Discovery is expected to continue in the coming months. At this time a loss is reasonably possible but not estimable, and as a result, no litigation reserve has been recorded on our consolidated balance sheet as of December 28, 2025.

As of December 29, 2024, the Company recordedno loss contingencies.

NOTE 17. 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 hasone operating segment andone reportable segment.

The CODM allocates resources and assesses performance of the Company based on net income (loss), as reported on the consolidated statement of operations, which as the segment measure of profit and loss that is closest to GAAP, is the required segment measure.
