Basis of Presentation and Principles of Consolidation

We prepared the accompanying consolidated financial statements following United States generally accepted accounting principles (“GAAP”). The financial statements include all normal and recurring adjustments that are necessary for a fair presentation of our financial position and operating results. The consolidated financial statements include the accounts of Leslie’s, Inc. and our subsidiaries. All significant intercompany accounts and transactions have been eliminated.

Fiscal Periods

We operate on a fiscal calendar that results in a fiscal year consisting of a 52- or 53-week period ending on the Saturday closest to September 30th. In a 52-week fiscal year, each quarter contains 13 weeks of operations; in a 53-week fiscal year, each of the first, second and third quarters includes 13 weeks of operations and the fourth quarter includes 14 weeks of operations. Fiscal 2025 is defined as the 53 weeks ended October 4, 2025, and fiscal 2024 and fiscal 2023 is defined as the 52 weeks ended September 28, 2024 and September 30, 2023.

Segment Reporting

Our Chief Operating Decision Maker is our Chief Executive Officer, who reviews financial information presented on a consolidated basis for purposes of allocating resources and assessing performance. We operate all of our locations in the United States and offer consumers similar products, services, and methods of distribution through our retail locations and e-commerce websites. As a result, we have a single reportable segment.

Seasonality

Our business is highly seasonal. Sales and earnings are highest during our third and fourth fiscal quarters, which include April through September, which represent the peak months of swimming pool use. Sales are substantially lower during our first and second fiscal quarters, when we typically generate net losses and we realize negative operating cash flow.

Use of Estimates

Management is required to make certain estimates and assumptions during the preparation of the consolidated financial statements in accordance with GAAP. These estimates and assumptions impact the reported amount of assets and liabilities and disclosures of contingent assets and liabilities as of the date of the consolidated financial statements. They also impact the reported amount of net income (loss) during any period. Actual results could differ from those estimates.

Significant estimates underlying the accompanying consolidated financial statements include inventory reserves, lease assumptions, vendor rebate programs, sales returns reserve, self-insurance liabilities, and the recoverability of intangible assets and goodwill.

Cash and Cash Equivalents

Fair Value Measurements

We use fair value measurements to record the fair value of certain assets and to estimate the fair value of financial instruments not recorded at fair value but required to be disclosed at fair value.

To determine the fair value, we maximize the use of observable inputs and minimize the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs market participants would use to value an asset or liability and are developed based on market data obtained from independent sources. Unobservable inputs are inputs based on assumptions about the factors market participants would use to value an asset or liability.

The fair value hierarchy is as follows, of which the first two are considered observable and the last unobservable:

As of October 4, 2025 and September 28, 2024, we held no assets that were required to be measured at fair value on a recurring basis. There were no transfers between levels in the fair value hierarchy during fiscal 2025, 2024, and 2023.

The fair value of our Amended and Restated Term Loan Credit Agreement (“Term Loan”) due in 2028 was determined to be $208.6 million and $758.2 million as of October 4, 2025 and September 28, 2024. These fair value estimates, determined to be

Level 2, are subjective in nature and involve uncertainties and matters of judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect these estimates.

We estimated the fair value of our one reporting unit in our goodwill impairment test performed using a combination of the income approach (discounted cash flow method) and market approach (comparable company multiples). Key assumptions used in the valuation techniques include future cash flow projections, long-term growth rates, and discount rates. The fair value estimates used in the goodwill impairment analysis are classified as Level 3 within the fair value hierarchy, due to significant unobservable inputs.

The carrying amounts of cash, cash equivalents, accounts receivable, accounts payable and accrued expenses approximate fair value due to the short-term maturity of these instruments.

Vendor Rebates

Many of our vendor arrangements provide for us to receive specified amounts of consideration when we meet the criteria defined in the agreement. Generally, the criteria relate to the volume level of purchases. We calculate the amount earned based on actual purchases, recorded as a reduction of the prices of the vendor’s products and therefore a reduction of inventory value at the end of each period based on a detailed analysis of inventory and of the facts and circumstances of various contractual agreements with vendors. We recognize rebates based on an estimated recognition pattern that assumes the oldest inventory is sold first, and we record this as a reduction of cost of merchandise and services sold in our consolidated statements of operations. Accounts and other receivables include vendor rebate receivables of $4.6 million and $21.8 million as of October 4, 2025 and September 28, 2024.

Allowance for Credit Losses

Inventories

Inventories are stated at the lower of cost or net realizable value. We value inventory using the average cost method which includes costs incurred to deliver inventory to our distribution centers including transportation, warehousing and distribution costs. We evaluate inventory for excess and obsolescence and record necessary reserves. We provide provisions for losses related to inventories based on management’s judgment regarding historical purchase cost, selling price, margin, movements, and current business trends. If actual demand or market conditions are different than those projected by management, future margins may be unfavorably or favorably affected by adjustments to these estimates. When an inventory item is sold or disposed, the associated reserve is released at that time.

Property and Equipment, Net

Property and equipment are stated at cost, less accumulated depreciation and amortization. Costs of normal maintenance and repairs are charged to expense as incurred. Major replacements or improvements of property and equipment are capitalized. When items are sold or otherwise disposed of, the cost and related accumulated depreciation or amortization are removed from the accounts, and any resulting gain or loss is included in our consolidated statements of operations.

We evaluate our long-lived assets for potential impairment whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. The evaluation for long-lived assets (asset group) is performed at the lowest level of identifiable cash flows, which, for location assets, is the individual location level. The assets of a physical location with indicators of impairment are evaluated for recoverability by comparing its undiscounted future cash flows with its carrying value. If the carrying value is greater than the undiscounted future cash flows, we then measure the asset’s fair value to determine whether an impairment loss should be recognized. If the resulting fair value is less than the carrying value, an impairment loss is recognized for the difference between the carrying value and the estimated fair value. Impairment charges are recorded in SG&A in our consolidated statements of operations.

We use estimates of market participant rents to calculate fair value of lease ROU assets and discounted future cash flows of the asset group to quantify fair value for other long-lived assets. These nonrecurring fair value measurements are considered Level 3 inputs as defined elsewhere in Note 2 Summary of Significant Accounting Policies - Fair Value Measurements of the notes to our consolidated financial statements. The impairment loss calculations require management to apply judgment estimating, among other things, market participant rents, future cash flows, and the discount rates that reflect the risk inherent in future cash flows. Future expected cash flows for assets in regular retail locations are based on management’s estimates of future cash flows over the remaining lease period or expected life, if shorter. For expected location closures, we evaluate whether it is necessary to shorten the useful life for any of the assets within the respective asset group.

Cloud Computing Arrangements

From time-to-time, we enter into various agreements with unaffiliated third parties for assistance with technical development work related to our security-related software and systems and other ongoing projects. Expenditures for implementation, set-up, and other upfront costs incurred in a cloud computing arrangement that is hosted by the vendor are capitalized generally in the same manner as internal use software and are recorded as other assets in our consolidated balance sheets. Such costs are amortized over the life of the related cloud computing arrangement. As of October 4, 2025 and September 28, 2024, $10.9 million and $9.4 million associated with these agreements are included in prepaid expenses and other current assets in our consolidated balance sheets, along with $34.4 million and $37.2 million associated with these agreements included in other assets in our consolidated balance sheets as of October 4, 2025 and September 28, 2024. In addition, for the year ended September 30, 2023, the Company recognized $6.3 million of expense in connection with the discontinued use of certain software subscriptions which is recorded in SG&A in our consolidated statements of operations and a corresponding $4.4 million liability for future obligations associated with these subscriptions. For the year ended October 4, 2025, there was $1.8 million liability remaining for those future obligations included in accrued expenses and other current liabilities in our consolidated balance sheets.

Goodwill and Other Intangibles, Net

Goodwill and intangible assets are recorded at their estimated fair values at the date of acquisition. We review goodwill and indefinite-lived intangible assets for impairment annually (in the fourth quarter) or more frequently if impairment indicators arise. Goodwill can be evaluated for impairment, at our option, by first performing a qualitative assessment to determine whether a quantitative goodwill test is necessary. If it is determined, based on qualitative factors, the fair value of the reporting unit may be more likely than not less than the carrying amount, a quantitative goodwill impairment test would be required. Additionally, we can elect to forgo a qualitative assessment and perform a quantitative test. The quantitative test is to identify if a potential impairment exists by comparing the fair value of a reporting unit with its carrying amount, including goodwill. If the carrying amount of the reporting unit exceeds the fair value, an impairment loss is recognized in an amount equal to that excess, not to exceed the carrying amount of goodwill.

If a quantitative test is performed, we would estimate the value considering our enterprise value and additionally the use of various valuation techniques which may use significant unobservable inputs, or Level 3 inputs, as defined by the fair value hierarchy. We include assumptions about sales growth, operating margins, discount rates and valuations multiples which consider our budgets, business plans, economic projections and marketplace data, and are believed to reflect market participant views which would exist in an exit transaction. Some of the inherent estimates and assumptions used in this analysis are outside the control of management, including cost of capital, tax rates and market EBITDA comparable financial metrics.

Finite-lived intangible assets are amortized to reflect the pattern of economic benefits consumed. We evaluate amortizable intangible assets for potential impairment whenever events or changes in circumstances indicate that the carrying amounts of the assets may not be fully recoverable. Intangible assets useful lives are reviewed annually.

For our indefinite life intangible assets, a qualitative assessment can also be performed to determine whether the existence of events and circumstances indicates it is more likely than not the intangible asset is impaired. Similar to goodwill, we can also elect to

forgo a qualitative test for indefinite life intangible assets and perform a quantitative test. Upon performing the quantitative test, if the carrying value of the intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. We evaluate whether certain trade names continue to have an indefinite life annually.

After we made our assessments, it was determined that there was no impairment related to other intangible assets in fiscal 2025, however we did record $180.7 million impairment on our goodwill during fiscal 2025. During fiscal 2024 and 2023 there was no impairment related to goodwill or other intangible assets. See Note 3 Goodwill and Other Intangibles, Net below for further details.

Leases

We enter into contractual arrangements for the utilization of certain non-owned assets which are evaluated as finance or operating leases upon commencement and are accounted for accordingly. Specifically, a contract is or contains a lease when (1) the contract contains an explicitly or implicitly identified asset and (2) we obtain substantially all of the economic benefits from the use of that underlying asset and direct how and for what purpose the asset is used during the term of the contract in exchange for consideration. We assess whether an arrangement is or contains a lease at inception of the contract.

We lease certain retail locations, warehouse and distribution space, office space, equipment, and vehicles. A substantial majority of our leases have an initial lease term of five years, typically with the option to extend the lease for at least one additional five-year term. Some of our leases may include the option to terminate in less than five years. The lease term used to calculate the right-of-use asset and lease liability at commencement includes the impacts of options to extend or terminate the lease when it is reasonably certain that we will exercise that option. When determining whether it is reasonably certain that we will exercise an option at commencement, we consider various existing economic factors, including market conditions, real estate strategies, the nature, length, and terms of the agreement, as well as the uncertainty of the condition of leased equipment at the end of the lease term. Based on these considerations, we generally conclude that the exercise of renewal options would not be reasonably certain in calculating our operating lease liability at commencement. The discount rate used to calculate the present value of lease payments is the rate implicit in the lease, when readily determinable. As the rate implicit in the lease is rarely readily determinable, we use a secured incremental borrowing rate, which is updated on a periodic basis as the discount rate for the present value of lease payments. Real estate taxes, insurance, maintenance, and operating expenses applicable to the leased property are generally our obligations under our lease agreements. In instances where these payments are fixed, they are included in the measurement of our lease liabilities, and when variable, are excluded and recognized in the period in which the obligation for those payments is incurred. For variable payments dependent upon an index or rate, we apply the active index or rate as of the lease commencement date. Variable lease payments not based on an index or rate are not included in the measurement of our operating lease liabilities as they cannot be reasonably estimated and are recognized in the period in which the obligation for those payments is incurred. Leases that have a term of 12 months or less upon commencement are considered short-term in nature and as such are not included in the measurement of our operating lease right-of-use assets and operating lease liabilities on the consolidated balance sheets and are expensed on a straight-line basis over the lease term. In addition, we do not separate lease and non-lease components (e.g., common area maintenance). Our lease agreements do not contain any material residual value guarantees or material restrictive covenants.

Revenue Recognition

Revenue is recognized when control of the promised goods or services is transferred to our customer, in an amount that reflects the consideration we expect to be entitled to in exchange for such goods or services. Revenue from merchandise sales at retail locations is recognized at the point of sale and revenue from services is recognized when the services are rendered. Revenue from e-commerce merchandise sales is recognized either at the time of pick-up at one of our locations or at the time of shipment, depending on the customer’s order designation. Revenue is recorded net of related discounts, loyalty point deferrals, and sales tax. Payment from retail customers is generally at the point of sale and payment terms for professional pool operators are based on our credit requirements and generally have terms of less than 60 days. When we receive payment from a consumer before the consumer has taken possession of the merchandise or the service has been performed, the amount received is recorded as deferred revenue or as a customer deposit until the sale or service is complete. Shipping and handling are treated as costs to fulfill the contract and not a separate performance obligation.

We estimate a liability for sales returns based on current sales levels and historical return trends. At each financial reporting date, we assess our estimates of expected returns, and a corresponding adjustment to cost of sales for our right to recover the goods returned by the customer, net of any expected recovery cost. Adjustments related to changes in return estimates were immaterial in all periods presented.

Cost of Merchandise and Services Sold

Cost of merchandise and services sold reflects the direct cost of purchased merchandise, costs to package certain chemical products, including direct materials and labor, costs to provide services, including labor and materials, as well as distribution and occupancy costs. Distribution costs include warehousing and transportation expenses, including costs associated with third-party fulfillment centers. Occupancy costs include the rent, common area maintenance, real estate taxes, and depreciation and amortization costs of all retail locations.

Selling, General and Administrative Expenses

Our SG&A includes selling and operating expenses at our retail locations and corporate level general and administrative expenses. Selling and operating expenses at retail locations include payroll, bonus and benefit costs for personnel, supplies, and credit and debit card processing costs. Corporate expenses include payroll, bonus, and benefit costs for our corporate and field support functions, equity-based compensation, marketing and advertising, insurance, utilities, occupancy costs related to our corporate office facilities, professional services, and depreciation and amortization for all assets, except those related to our retail locations and distribution operations, which are included in cost of merchandise and services sold.

Advertising

We expense advertising costs as incurred. Advertising costs for fiscal 2025, 2024, and 2023 were $30.2 million, $33.4 million, and $35.1 million.

Income Taxes

We account for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts and tax bases of existing assets and liabilities. Deferred tax assets, including the benefit of net operating loss and tax credit carryforwards, are evaluated based on the guidelines for realization and are reduced by a valuation allowance if it is deemed more likely than not that such assets will not be realized. We consider several factors in evaluating the realizability of our deferred tax assets, including the nature, frequency and severity of recent losses, the remaining years available for carryforwards, the timing of the reversals of year end deferred tax assets and liabilities, changes in tax laws, the future profitability of the operations in the jurisdiction, and tax planning strategies. Our judgments and estimates concerning realizability of deferred tax assets could change if any of the evaluation factors change, resulting in an increase or decrease to income tax expense in any period.

The ultimate realization of deferred tax assets can be dependent upon the generation of future taxable income during the periods in which the associated temporary differences become deductible. On a quarterly basis, we evaluate whether it is more likely than not that our deferred tax assets will be realized in the future and conclude whether a valuation allowance must be established.

We record a liability for uncertain tax positions to the extent a tax position taken or expected to be taken in a tax return does not meet certain recognition or measurement criteria. Considerable management judgment is necessary to assess the inherent uncertainties related to the interpretations of complex tax laws, regulations and taxing authority rulings. Our judgments and estimates may change as a result of the evaluation of new information, such as the outcome of tax audits or changes to or further interpretations of tax laws and regulations, resulting in an increase or decrease to income tax expense in any period. Interest and penalties accrued, if any, relating to uncertain tax positions will be recognized as a component of the income tax provision.

Equity-Based Compensation

Stock-based compensation expense is measured at grant date, based on the fair value of the award, and is recognized on a straight-line basis over the requisite service period for awards expected to vest. See Note 14—Equity-Based Compensation for further discussion.

Self-Insurance Reserves

Earnings per Share

Basic earnings per share is calculated by dividing net income by the weighted average number of shares outstanding during the period. Diluted earnings per share is computed giving effect to all potentially dilutive shares, unless their effect is antidilutive. We apply the treasury stock method for dilutive share-based awards. Performance-based share-based awards are included in diluted shares only if the related performance conditions have been considered satisfied as of the end of the reporting period. Additionally, all per share amounts have been recast to account for the Reverse Stock Split.

Recent Accounting Pronouncements

In September 2025, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 335-40): Targeted Improvements to the Accounting for Internal-Use Software. The guidance modernizes and clarifies the threshold for when an entity is required to start capitalizing software costs and is based on when (i) management has authorized and committed to funding the software project and (ii) it is probable that the project will be completed and the software will be used to perform the function intended. The amendments in ASU 2025-06 are effective for fiscal years beginning after December 15, 2027, and interim reporting periods within those annual reporting periods. We are currently evaluating the ASU to determine its impact on our consolidated financial statements and disclosures; however, we do not expect there to be a material impact.

In January 2025, FASB issued ASU No. 2025-01, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 2020-40): Disaggregation of Income Statement Expenses. This update clarifies the initial effective date for entities that do not have an annual reporting period that ends on December 31 to be the first annual reporting period beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. We are currently evaluating the ASU to determine its impact on our disclosures; however, we do not expect there to be a material impact.

In November 2024, FASB issued ASU No. 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. This update requires additional disclosures over certain expenses, including purchases of inventory, employee compensation, depreciation, intangible asset amortization, and other specific expense categories. This standard also requires disclosure of the total amount of selling expenses and the Company's definition of selling expenses. This update is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. We are currently evaluating the ASU to determine its impact on our disclosures; however, we do not expect there to be a material impact.

In December 2023, FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which includes amendments that further enhance income tax disclosures, primarily through standardization and disaggregation of rate reconciliation categories and income taxes paid by jurisdiction. This update is effective for annual periods beginning after December 15, 2024, though early adoption is permitted. We are currently evaluating the ASU to determine its impact on our disclosures; however, we do not expect there to be a material impact.

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The amended guidance requires incremental reportable segment disclosures, primarily about significant segment expenses. The amendments also require entities with a single reportable segment to provide all disclosures required by these amendments, and all existing segment disclosures. The amendments will be applied retrospectively to all prior periods presented in the financial statements and is effective for fiscal years beginning after December 15, 2023, and interim periods in fiscal years

beginning after December 15, 2024, with early adoption permitted. We adopted this guidance in the fourth quarter of 2025. For additional information, see Note 16—Segment Reporting.

There are other new accounting pronouncements issued by the FASB that we have adopted or will adopt, as applicable. We do not believe any of these new accounting pronouncements have had, or will have, a material impact on our consolidated financial statements or disclosures.
