Accounting Policies [Abstract]

Summary of Significant Accounting Policies

2. Summary of Significant Accounting Policies

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of the Company. All material intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements. Estimates also affect the reported amounts of revenue and expenses during the periods reported. Some of the significant estimates that we have made pertain to the determination of deferred tax assets and liabilities; estimates utilized to determine the fair value of assets acquired and liabilities assumed in business combinations and the related goodwill and intangibles; and certain assumptions used related to the evaluation of goodwill, intangibles, and property and equipment asset impairment. Actual results could differ from those estimates.

Cash and Cash Equivalents, and Restricted Cash

We consider all highly liquid investments with original maturities of three months or less to be cash equivalents. We place our temporary cash investments with high credit quality financial institutions. At times, such investments may exceed federally insured limits; however, management does not believe we are exposed to any significant credit risk on counter party cash and cash equivalents.

On occasion, we are required to maintain restricted cash deposits with certain banks due to contractual or other legal obligations. At December 31, 2025 and 2024, we had $61 and $149, respectively, in restricted cash set aside for the funding of various maintenance expenses. Restricted cash is recorded in Prepaid expenses and other current assets in the consolidated balance sheets.

Accounts Receivable, Net

Accounts receivable, net includes amounts due for consumer credit card sales and other trade accounts receivable. We provide an allowance for doubtful accounts using an expected credit loss model which represents our estimate of expected credit losses over the lifetime of the asset. Recoveries of trade receivables previously written off are recorded when received. Accounts receivable are presented net of an allowance for doubtful accounts of $31 and $123 at December 31, 2025 and 2024, respectively. The activity in the allowance for doubtful accounts was immaterial for the years ended December 31, 2025, 2024 and 2023.

Other Receivables

Other receivables consist primarily of payroll tax withholding and exercise proceeds receivables, construction receivables and insurance receivable from non-healthcare related insurance claims.

We record payroll tax withholding and exercise proceeds receivable for amounts due to us from a third-party broker for amounts used to cover tax liability and exercise proceeds resulting from employee exercises of share-based payment awards.

For certain build-to-suit lease arrangements, we are responsible for the construction of a lessor owned facility using our designs. As construction occurs, we will recognize a construction receivable on the consolidated balance sheets due from the lessor. To the extent costs exceed the amount to be reimbursed by the lessor, we will consider such costs prepaid rent, which are added to the associated operating lease right of use asset once the lease commences.

We carry a broad range of insurance coverage, including general and business auto liability, commercial property, workers’ compensation, cyber risk, and general umbrella policies. We record receivables from our non-healthcare insurance carriers related to these insurance claims, which are included in other receivables. The receivables are paid when the claim is finalized and the reserved amounts on these claims are expected to be paid within one year.


	As of
	December 31, 2025		December 31, 2024
Payroll tax withholding and exercise proceeds receivable	$	—	$	834
Construction receivable		4,960		4,584
Income tax receivable		1,011		1,864
Insurance receivable		4,921		4,250
Employee retention credit receivable		1,635		-
Other		2,958		1,986
Total other receivables	$	15,485	$	13,518

Inventory, Net

Inventory, net consists primarily of chemical washing solutions and is stated at the lower of cost or net realizable value using the average cost method. The activity in the reserve for obsolescence accounts was immaterial for the years ended December 31, 2025, 2024 and 2023.

Inventory for the periods presented is as follows:


	As of
	December 31, 2025			December 31, 2024
Chemical washing solutions	$	5,537		$	5,831
Other		60			14
Total inventory, gross		5,597			5,845
Reserve for obsolescence		(112	)		(117	)
Total inventory, net	$	5,485		$	5,728

Property and Equipment, Net

Property and equipment purchased are stated at cost less accumulated depreciation. Assets acquired in business combinations are recorded at fair value. Depreciation and amortization are recorded using the straight-line method over the estimated useful lives of the property or related lease term. Amortization of assets under finance leases is included in depreciation expense. Estimated useful lives range from 10 to 40 years for buildings and leasehold improvements, and from 3 to 7 years for machinery and equipment.

Expenditures for repairs and maintenance are charged to expense as incurred. Expenditures for major renewals and betterments that extend the useful lives of existing equipment are capitalized.

For items that are disposed of, the cost and related accumulated depreciation are removed from the accounts and any resulting gain or loss is recognized as (gain) loss on sale of assets, net in the accompanying consolidated statements of operations and comprehensive income.

The carrying value of long-lived assets held and used is periodically reviewed for possible impairment when events and circumstances warrant such a review.

Other Intangible Assets, Net and Goodwill

We classify intangible assets into three categories: (1) intangible assets with definite lives subject to amortization, (2) intangible assets with indefinite lives not subject to amortization and (3) goodwill. The useful lives of our identifiable intangible assets are determined after considering the specific facts and circumstances related to each intangible asset. The following factors are considered when determining useful lives: the contractual term of any agreement related to the asset, the historical performance of the asset, our long-term strategy for using the asset, any laws or other local regulations which could impact the useful life of the asset, and other economic factors, including competition and specific market conditions.

Intangible assets that are deemed to have definite lives are amortized, primarily on a straight-line basis, over their useful lives, generally ranging from 2 to 10 years. When facts and circumstances indicate that the carrying value of definite-lived intangible assets may not be recoverable, management assesses the recoverability of the carrying value by preparing estimates of sales volume and the resulting profit and cash flows expected to result from the use of the asset or asset group and its eventual disposition. If the sum of the expected future cash flows (undiscounted and without interest charges) is less than the carrying amount, we will recognize an impairment loss. The impairment loss recognized is the amount by which the carrying amount of the asset or asset group exceeds the fair value. We use a variety of methodologies to determine the fair value of these assets, including discounted cash flow models, which are consistent with the assumptions hypothetical marketplace participants would use.

Intangible assets determined to have indefinite useful lives, including trade names and trademarks, are tested for impairment annually, or more frequently if events or circumstances indicate that assets might be impaired. A variety of methodologies are used in conducting impairment assessments of indefinite-lived intangible assets, including, but not limited to, discounted cash flow models, which are based on the assumptions we believe hypothetical marketplace participants would use. For indefinite-lived intangible assets, other than goodwill, if the carrying amount exceeds the fair value, an impairment charge is recognized in an amount equal to that excess. We have the option to perform a qualitative assessment of indefinite-lived intangible assets, other than goodwill, rather than completing the impairment test. We must assess whether it is more likely than not that the fair value of the intangible asset is less than its carrying amount. If we conclude that this is the case, we must perform the testing described above. Otherwise, we do not need to perform any further assessment. We completed our indefinite-life intangible asset impairment analysis as of October 31, 2025 and 2024 and concluded that it was not more likely than not that the carrying value of the asset may not be recoverable.

Goodwill is evaluated for impairment at the reporting unit-level on an annual basis (or more frequently if events or circumstances indicate that the related carrying amount may be impaired). We evaluate qualitative factors to determine if performing the quantitative impairment test is required. If it is determined that it is more likely than not, as defined in the guidance, that the carrying value is less than the fair value, the potential for goodwill impairment is evaluated and the amount of impairment loss, if any, is measured and recognized. If we determine that it is not more likely than not that the carrying value is less than the fair value, no further evaluation is performed. We completed our goodwill impairment test as of October 31, 2025 and 2024 and concluded that it is not more likely than not that the carrying value is less than the fair value, and therefore, no further evaluation was performed.

Derivative Financial Instruments

The Company has a pay fixed, receive variable interest rate swap contract (“Swap”) to manage its exposure to changes in interest rates. The Swap is recognized in the consolidated balance sheets at fair value. The Swap is a cash flow hedge and is recorded using hedge accounting, as such, changes in the fair value of the Swap are recorded in other comprehensive loss, net of tax until the hedged item is recognized in earnings. Amounts reported in other comprehensive loss, net of tax related to the Swap are reclassified to interest expense as interest payments are made on the Company’s variable-rate debt. The swap is scheduled to terminate June 30, 2027.

The Company assesses, both at the inception of the hedge and on an ongoing basis, whether the derivative used as a hedging instrument is highly effective in offsetting the changes in the cash flow of the hedged item. If it is determined that the derivative is not highly effective as a hedge or ceases to be highly effective, the Company will discontinue hedge accounting prospectively. See Note 10 Fair Value Measurements and Note 11 Interest Rate Swap for additional information.

Deferred Debt Issuance Costs

Debt issuance costs related to a recognized debt liability are presented in the consolidated balance sheets as a direct deduction from the carrying value of the related liability except for debt issuance costs related to our Revolving Commitment arrangement. In the case of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement, related debt issuance costs are presented in other assets in the accompanying consolidated balance sheets.

The direct costs associated with the funding of long-term debt are amortized to interest expense over the term of the applicable loan.

Leases

We determine if a contract contains a lease at inception. Our material operating leases consist of car wash locations, warehouses and office space. U.S. GAAP requires that our leases be evaluated and classified as operating or finance leases for financial reporting purposes. The classification evaluation begins at the commencement date, and the lease term used in the evaluation includes the non-cancelable period for which we have the right to use the underlying asset, together with renewal option periods when the exercise of the renewal option is reasonably certain and failure to exercise such option would result in an economic penalty. Nearly all of our car wash and office space leases are classified as operating leases.

We disburse cash for leasehold improvements, furniture and fixtures and equipment to build out and equip our leased premises. Tenant improvement allowance incentives may be available to partially offset the cost of developing and opening the related car washes, pursuant to agreed-upon terms in the respective lease agreements. Tenant improvement allowances can take the form of cash payments upon the opening of the related car washes, full or partial credits against rents otherwise payable by us, or a combination thereof. All tenant improvement allowances we receive are recorded as a contra operating lease right of use asset and amortized over the term of the lease.

The lease term used for straight-line rent expense is calculated from the commencement date (the date we take possession of the premises) through the lease termination date (including any options where exercise is reasonably certain and failure to exercise such option would result in an economic penalty). The initial lease term of our operating leases ranges from 6 to 50 years. We record rent expense on a straight-line basis beginning on the lease commencement date.

Maintenance, insurance and property tax expenses are generally accounted for on an accrual basis as variable lease costs. We recognize variable lease cost for operating leases in the period when changes in facts and circumstances on which the variable lease payments are based occur. All operating lease rent expense is included in other store operating expenses or general and administrative expense on the consolidated statements of operations and comprehensive income.

We record a lease liability for our operating leases equal to the present value of future payments discounted at the estimated fully collateralized incremental borrowing rate (discount rate) corresponding with the lease term as the rate implicit in our leases is not readily determinable. Our operating lease liability calculation is the total rent payable during the lease term, including rent escalations in which the amount of future rent is certain or fixed on the straight-line basis over the term of the lease (including any rent holiday period beginning upon our possession of the premises, and any fixed payments stated in the lease). A corresponding operating lease asset is also recorded equaling the initial amount of the operating lease liability, plus any lease payments made to the lessor before or at the lease commencement date and any initial direct costs incurred, less any lease incentives received. The difference between the minimum rents paid and the straight-line rent is reflected within the associated operating lease right of use asset.

Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. Additionally, we do not enter into lease transactions with related parties.

We make judgments regarding the reasonably certain lease term for each car wash property lease, which can impact the classification and accounting for a lease as finance or operating and/or escalations in payments that are taken into consideration when calculating straight-line rent, and the term over which leasehold improvements for each car wash are amortized. These judgments may produce materially different amounts of depreciation, amortization and rent expense than would be reported if different assumed lease terms were used.

Revenue Recognition

A five-step model is used to recognize revenue from customer contracts under ASC 606, Revenue from Contracts with Customers (ASC 606). The five-step model requires that we (i) identify the contract with the customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, including variable consideration to the extent that it is probable that a significant future reversal will not occur, (iv) allocate the transaction price to the respective performance obligations in the contract, and (v) recognize revenue when (or as) we satisfy the performance obligation.

We recognize revenue in two main streams. First, we offer an Unlimited Wash Club® (“UWC”) program to our customers. The UWC program entitles the customer to unlimited washes for a monthly fee, cancelable at any time.

We enter into a contract with the customer that falls under the definition of a customer contract under ASC 606. Customers are automatically charged on a credit or debit card on the same day of the month that they originally signed up. Our performance obligation is to provide unlimited car wash services for a monthly fee. The UWC revenue is recognized ratably daily over the month in which it is earned and amounts unearned are recorded as deferred revenue on the consolidated balance sheets. All amounts recorded as deferred revenue at year end are recognized as revenue in the following year. Second, revenue from car wash services are recognized at the point in time services are rendered and the customer pays with cash or credit. Revenues are net of sales tax, refunds and discounts applied as a reduction of revenue at the time of payment.

The following table summarizes the composition of our net revenues for the periods presented:


	Year Ended December 31,
	2025		2024		2023
Recognized over time	$	801,006	$	734,235	$	659,612
Recognized at a point in time		249,500		260,034		267,067
Other revenue		1,225		458		391
Net revenues	$	1,051,731	$	994,727	$	927,070

We promote and sell a limited number of prepaid products, which include discounted car wash packages and gift cards that are not material to the financial statements. We record the sale of these items as deferred revenue, which is reduced for estimated breakage, which is not material to the financial statements. Revenue is recognized based on the terms of the packages and when the prepaid packages or gift cards are redeemed by the customer.

Cost of Labor and Chemicals

Cost of labor and chemicals include labor costs associated with car wash employees, maintenance employees, warehouse employees, and chemicals and associated supplies. The related employee benefits for the aforementioned employees, such as taxes, insurance and workers compensation, are also included in the cost of labor and chemicals.

Other Store Operating Expenses

Other store operating expenses includes all other costs related to the operations of car wash and warehouse locations such as credit card fees, car damages, office and lobby supplies, information technology costs associated with the locations, telecommunications, advertising, non-healthcare related insurance, rent, repairs and maintenance related to held-for-use assets, utilities, property taxes, and depreciation on held-for-use assets at the car wash and warehouse locations.

Sales and Marketing

Sales and marketing expenses are expensed as incurred and include costs for advertising, onsite collateral, promotional events and sponsorships, and customer retention. Advertising costs totaled approximately $7,617, $4,253 and $7,048 for the years ended December 31, 2025, 2024, and 2023, respectively, and are recorded in other store operating expenses in the consolidated statements of operations and comprehensive income.

Income Taxes

Deferred tax assets and liabilities are recognized for the expected future tax consequences of events that have been recognized differently in the financial statements or tax returns. Under this method, deferred tax liabilities and assets are determined based on the difference between the financial statement carrying amounts and tax basis of assets and liabilities using enacted tax rates.

We have adopted a more likely than not threshold for financial statement recognition and measurement of an uncertain tax position taken or expected to be taken in a tax return. We recognize interest and penalties related to uncertain tax positions in income tax provision in the consolidated statements of operations and comprehensive income.

Sales Taxes

We collect sales taxes from customers for taxable services provided and products sold and remit those collected sales and use taxes to the applicable state authorities on a monthly basis. We have adopted a policy of presenting such taxes on revenues on a net basis (excluded from revenues) in the consolidated statements of operations and comprehensive income.

Stock-Based Compensation Plans

Stock-based compensation represents the cost related to stock-based awards granted to employees. We measure stock-based compensation cost at grant date, based upon the estimated fair value of the award, and recognize cost as expense using the tranche over the employee requisite service period. We estimate the fair value of stock options and stock purchase rights using a Black-Scholes option-pricing model. Restricted stock units are classified as equity and measured at the fair market value of the underlying stock at the grant date. Upon termination unvested time and performance-based options, stock-purchase rights, and restricted stock units are forfeited. We have made a policy election to estimate the number of stock-based compensation awards that are expected to vest to determine the amount of compensation expense recognized in earnings. Forfeiture estimates are revised if subsequent information indicates that the actual number of forfeitures is likely to differ from previous estimates.

Deferred tax assets are recorded for awards that result in deductions in our income tax returns, based upon the amount of compensation cost recognized and our statutory tax rate. The tax effect of differences between the compensation cost of an award recognized for financial reporting purposes and the deduction for an award for tax purposes is recognized as an income tax expense or benefit in the consolidated statements of operations and comprehensive income in the period in which the tax deduction arises.

Business Combinations

We evaluate each transaction under ASC 805, Business Combinations, including applying a screen test to evaluate if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets to determine whether a transaction is accounted for as an asset acquisition or business combination.

For all business acquisitions, we recognize, separately from goodwill, the identifiable assets acquired, and liabilities assumed at their estimated acquisition-date fair values. We measure and recognize goodwill as of the acquisition date as the excess of the aggregate of the fair value of consideration transferred over the fair value of assets acquired and liabilities assumed.

To the extent contingencies such as pre-acquisition environmental matters, contingent purchase price consideration, litigation, and related legal fees are resolved or settled during a reporting period after a business combination occurs, the effect of changes in such contingencies is included in results of operations in the periods in which the adjustments are determined. We recognize third-party transaction-related costs as general and administrative in the period in which those costs are incurred.

If information about facts and circumstances existing as of the acquisition date is incomplete by the end of the reporting period in which a business combination occurs, we report provisional amounts for the items for which the accounting is incomplete. This period will not exceed one year from the acquisition date. Any material adjustments recognized during the measurement period are reflected prospectively in the consolidated financial statements of the subsequent period.

Fair Value Measurements

We disclose the fair value of our financial instruments based on the fair value hierarchy. The levels of the fair value hierarchy are described as follows:

Level 1—Financial assets and liabilities whose values are based on unadjusted quoted market prices for identical assets and liabilities in an active market that we have the ability to access.

Level 2—Financial assets and liabilities whose values are based on quoted prices in markets that are not active, or model inputs that are observable for substantially the full term of the asset or liability.

Level 3—Financial assets and liabilities whose values are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement.

We use observable market data, when available, in making fair value measurements. When inputs used to measure fair value fall within different levels of the hierarchy, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement. See Note 10 Fair Value Measurements in the consolidated financial statements for additional information regarding the contingent consideration liability.

Employee Retention Credit

In response to the COVID-19 pandemic, the Employee Retention Credit (“ERC”), was established under the Coronavirus Aid, Relief, and Economic Security Act. The ERC is a refundable tax credit against certain employment taxes equal to 50% of the qualified wages an eligible employer paid to employees from March 13, 2020 to December 31, 2020. Companies who meet the eligibility requirements can claim the ERC on an original or adjusted employment tax return for a period within those dates.

In March 2024, we determined that we qualify for $4,663 (net of tax advisory costs) in relief for the period from March 13, 2020 to December 31, 2020. Upon receipt of the credit, we will owe an immaterial amount for tax advisory costs associated with the assessment of the tax credit. As there is no authoritative guidance under U.S. GAAP for government assistance to for-profit business entities, the Company accounts for the ERC by analogy to International Accounting Standards 20, or IAS 20, Accounting for Government Grants and Disclosure of Government Assistance. In accordance with IAS 20, management determined it has reasonable assurance of receipt of the identified ERC amount and recorded the credit in other income on our consolidated statements of operations and comprehensive income.

As of December 31, 2025 and December 31, 2024, the tax credit receivable was $1,635 and $4,663, respectively. As of December 31, 2025 and December 31, 2024, these amounts are included in other receivables and other assets, respectively, on our consolidated balance sheets.

Recently Adopted Accounting Pronouncements

In 2025 we retrospectively adopted ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which focuses on the transparency of income tax disclosures by requiring specified categories and greater disaggregation of information in the effective tax rate reconciliation and income taxes paid disaggregated by jurisdiction. It also includes certain other amendments to improve the effectiveness of income tax disclosure. The adoption of this guidance did not have an impact on our financial statements, although it did result in expanded income tax-related disclosures. See Note 8 Income Taxes in the consolidated financial statements for additional information.

Recently Issued Accounting Pronouncements Not Yet Adopted

In November 2024, the FASB issued ASU No. 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires a PBE to disclose additional information about specific expense categories in the notes to financial statements at interim and annual periods. This information is generally not presented in the financial statements. The ASU requires that at each interim and annual period a PBE: (1) disclose the amounts of (a) purchases of inventory, (b) employee compensation, (c) depreciation, (d) intangible asset amortization, and (e) depreciation, depletion, and amortization; (2) include certain amounts that are already required to be disclosed under current U.S. GAAP in the same disclosure as the other disaggregation requirements; (3) disclose a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively, and (4) disclose the total amount of selling expenses and, in annual reporting periods, an entity's definition of selling expenses. The ASU is effective for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027, with early adoption permitted. The guidance should be applied either prospectively to financial statements issued for periods after the effective date of this ASU or retrospectively to any or all prior periods presented in the financial statements. We are still assessing the impact of this ASU.

In September 2025, the FASB issued ASU No. 2025-06, Targeted Improvements to the Accounting for Internal-Use Software. This ASU is intended to improve the operability and application of guidance related to capitalized software development costs. The ASU is effective for annual periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods, with early adoption permitted. We are still assessing the impact of this ASU.

In December 2025, the FASB issued ASU No. 2025-11, Narrow-Scope Improvements to Interim Reporting (Topic 270). This ASU is intended to clarify interim disclosure requirements and the applicability of Topic 270. The ASU is effective for interim reporting periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted. We are still assessing the impact of this ASU.

A reconciliation of the statutory income tax rate and provision to our effective tax rate and total tax provision consisted of the following for the periods presented:


	Year Ended December 31,

The income tax expense recorded in 2025 is different from the expected statutory federal and state tax expense primarily due to a $2,963 income tax expense related to equity award exercises and/or vesting in 2025, which is net of the impact of the internal revenue code rules and regulations related to the deductibility of executive compensation by publicly held companies.

We had federal and state net operating loss (“NOL”) carryforwards available of $108,915 and $85,218 at December 31, 2025, respectively. The federal NOL carryforwards can be carried forward indefinitely while $38,889 of the state NOL carryforwards have indefinite lives and the remaining amounts will expire between 2036 and 2043. We had federal interest expense carryforwards of $108,357 at December 31, 2025

, which can be carried forward indefinitely. We also had state interest expense carryforwards in 12 states where the amounts vary by jurisdiction, which also have indefinite lives. We had federal and state R&D and other business tax credit carryforwards of $3,283 and $1,119 at December 31, 2025, respectively. The federal business tax credit carryforwards can be carried forward for 20 years and will expire between 2039 and 2045. The state R&D and other business tax credit carryforwards can be carried forward for 5 to 20 years and will expire between 2029 and 2038.

As noted above, we had deferred tax assets related to both federal and state NOL and interest expense carryforwards. When determining the need for a valuation allowance, we consider all available positive and negative evidence, including taxable income in prior carryback years (if carryback is permitted under the relevant tax law), the timing of the reversal of existing taxable temporary differences, tax planning strategies and projected future taxable income. We adjust the valuation allowance in the period management determines it is more likely than not that we will not realize some or all of the deferred tax assets.

For financial reporting purposes, we established valuation allowances of $290 and $262 at December 31, 2025 and 2024, respectively, to offset deferred tax assets. The current and prior year valuation allowance relates to state attributes and carryovers.

On July 4, 2025, the “One Big Beautiful Bill Act” (the “OBBBA”) was signed into law. The OBBBA includes tax reform provisions including 100% bonus depreciation, full expensing of domestic research expenditures, and modifications to interest expense limitations. After initial evaluation, the Company does not currently expect these laws to have a material effect on tax expense or the anticipated annual effective tax rate. We expect certain provisions effective for the 2025 tax year will decrease current and future cash taxes paid on the consolidated financial statements.

Past ownership changes and other equity transactions may have triggered Sections 382 and 383 of the Internal Revenue Code, resulting in certain annual limitations on the utilization of existing federal and state net operating losses and credits. Such provisions may limit the potential future tax benefit to be realized by us from its accumulated net operating losses and tax credit carryforwards.

We file income tax returns in the U.S. federal and various state tax jurisdictions and are subject to varying statutes of limitation in each jurisdiction. As of December 31, 2025, we are not under audit for federal or state income tax purposes. In general, our federal tax return may be subject to examination for the 2022 through 2024 tax years, while for state purposes, the 2021 through 2024 years are generally open to examination, with some states having either a three- or four-year statute of limitations. Our usage of NOL carryovers also permits taxing authorities to adjust aspects of tax returns that may be outside of these statutes of limitation.

A table of income taxes paid is as follows:


	Year Ended December 31,
	2025			2024			2023
Federal	$	79		$	-		$	(161	)

Cash paid for income taxes, net of refunds	$	831		$	862		$	3,256

(a)

The amount of income taxes paid during the year does not meet the 5% disaggregation threshold and is included in 'Other'.

A reconciliation of the beginning and ending amounts of gross unrecognized tax benefits is as follows:


	Year Ended December 31,
	2025		2024		2023
Tax contingencies at beginning of period	$	542	$	-	$	-
Additions based on tax positions related to the current year		95		83		-
Additions based on tax positions related to prior years		-		459		-
Tax contingencies at end of period	$	637	$	542	$	-

We had gross unrecognized tax benefits of $637 and $542 as of December 31, 2025 and 2024, respectively, related to federal and state R&D tax credits. All of the unrecognized tax benefits, if recognized, would affect the effective tax rate.

We accrued interest and penalties of $12 and $42 as of December 31, 2025 and 2024, respectively, in income tax expense.

For the years ended December 31, 2025, 2024 and 2023, the amortization of debt issuance costs in interest expense, net in the consolidated statements of operations and comprehensive income was approximately $1,103, $1,256 and $1,698, respectively.

Amended and Restated First Lien Credit Agreement

On August 21, 2014, we entered into a Credit Agreement (“Credit Agreement”) which was originally comprised of a term loan (“First Lien Term Loan”) and a revolving commitment (“Revolving Commitment”), which was subsequently amended and restated. The Credit Agreement was collateralized by substantially all personal property (including cash, inventory, property and equipment, and intangible assets), real property, and equity interests owned by us.

First Lien Term Loan

In March 2024, we entered into Amendment No. 5 to the Credit Agreement with the lenders party thereto, and Bank of America, N.A. (“BofA”) as the successor administrative agent and collateral agent. This amendment further modified the Credit Agreement by providing $925,000 in first lien term commitments, consisting of $901,201 to refinance outstanding term loans and $23,799 in additional incremental term commitments (collectively, the “2024 Term Loans”). Starting September 30, 2024, the loans will be amortized in equal quarterly installments at an annual rate of 1.00% of the original principal amount. In connection with Amendment No. 5, we expensed $1,882 of previously unamortized debt issuance costs as a loss on extinguishment of debt in the consolidated statements of operations and comprehensive income.

In November 2024, we entered into Amendment No. 6 to the Credit Agreement with the lenders party thereto, and BofA as the successor administrative agent and collateral agent. This amendment further modified the Credit Agreement by resetting the soft call protection of 1% for voluntary prepayments of the Term Loans to last for six months after the effective date of this Amendment, as well as repricing the Term and Revolving Loans margins, where each was reduced by 0.25%. In connection with Amendment No. 6, we expensed $94 of previously unamortized debt issuance costs as a loss on extinguishment of debt in the consolidated statements of operations and comprehensive income.

The First Lien Term Loan borrowings bear interest equal to the SOFR rate plus a margin, with margin starting at 2.75% and can decrease to 2.50% and 2.25% based on the First Lien Net Leverage Ratio.

Revolving Commitment

Amendment No. 5 to our Credit Agreement also increased our borrowing capacity from $150,000 to $300,000. Any unused commitment fee is also payable based on the First Lien Net Leverage Ratio. The Credit Agreement requires a Rent Adjusted Total Net Leverage Ratio no greater than 6.50 to 1.00, tested quarterly beginning with the quarter ending September 30, 2024, for the benefit of lenders holding the Revolving Commitment.

The maximum available borrowing capacity under the Revolving Commitment is reduced by outstanding letters of credit under the Revolving Commitment. As of December 31, 2025 and 2024, the available borrowing capacity under the Revolving Commitment was $299,926 and $299,791, respectively.

In addition, an unused commitment fee based on our First Lien Net Leverage Ratio is payable on the average of the unused borrowing capacity under the Revolving Commitment. As of December 31, 2025 and 2024, the unused commitment fee was 0.20% and 0.25%, respectively.

Standby Letters of Credit

As of December 31, 2025, we have a letter of credit sublimit of $90,000 under the Revolving Commitment, provided that the total utilization of revolving commitments under the Revolving Commitment does not exceed $300,000. Any letter of credit issued under the Credit Agreement has an expiration date which is the earlier of (i) no later than 12 months from the date of issuance or (ii) five business days prior to the maturity date of the Revolving Commitment, as amended under Amendment No. 2 to the Credit Agreement. Letters of credit under the Revolving Commitment reduce the maximum available borrowing capacity under the Revolving Commitment. As of December 31, 2025 and 2024, the amounts associated with outstanding letters of credit were $74 and $209, respectively.

Credit Agreement

We were in compliance with all covenants related to our long-term debt as of December 31, 2025.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

18. Commitments and Contingencies

Litigation

From time to time, we are party to pending or threatened lawsuits arising out of or incident to the ordinary course of business. We carry professional and general liability insurance coverage and other insurance coverages. In the opinion of management and upon consultation with legal counsel, none of the pending or threatened lawsuits will have a material effect upon the consolidated financial position, operations, or cash flows of the Company.

Insurance

We carry a broad range of insurance coverage, including general and business auto liability, commercial property, workers’ compensation, cyber risk, directors and officers, and general umbrella policies. As of December 31, 2025 and 2024, we accrued $6,027 and $4,803, respectively, for assessments on insurance claims filed, which are included in other accrued expenses in the accompanying consolidated balance sheets. As of December 31, 2025 and 2024, we recorded $4,921 and $4,250, respectively, in other receivables from our non-healthcare insurance carriers related to these insurance claims, which are included in other receivables in the accompanying consolidated balance sheets. The receivables are paid when the claim is finalized and the reserved amounts on these claims are expected to be paid within one year.

Environmental Matters

Operations at certain facilities currently or previously owned or leased by us utilize, or in the past have utilized, hazardous substances generally in compliance with applicable law. Periodically, we have had minor claims asserted against us by regulatory agencies or private parties for environmental matters relating to the handling of hazardous substances by us, and we have incurred obligations for investigations or remedial actions with respect to certain of these matters. There can be no assurances that activities at these facilities, or future facilities owned or operated by us, may not result in additional environmental claims being asserted against us or additional investigations or remedial actions being required. We are not aware of any significant remediation matters as of December 31, 2025. Because of various factors including the difficulty of identifying the responsible parties for any particular site, the complexity of determining the relative liability among them, the uncertainty as to the most desirable remediation techniques and the amount of damages and clean-up costs and the time period during which such costs may be incurred, we are unable to reasonably estimate the ultimate cost of claims asserted against us related to environmental matters; however, we do not believe such costs will be material to its consolidated financial statements.

In addition to potential claims asserted against us, there are certain regulatory obligations associated with these facilities. We also have a third-party specialist to review the sites subject to these regulations annually, for the purpose of assigning future cost. A third party has conducted a preliminary assessment of site restoration provisions arising from these regulations and we have recognized a provisional amount. As of December 31, 2025 and 2024,

we recorded an environmental remediation accrual of $194 and $25, respectively, which is included in other accrued expenses in the accompanying consolidated balance sheets.

Forward Starting Leases

As of December 31, 2025, we entered into eight leases that had not yet commenced related to build-to-suit arrangements for car wash locations. These leases will commence in years 2026 through 2028 with initial lease terms of 15 to 20 years.

As of December 31, 2024, we entered into 10 leases that had not yet commenced related to build-to-suit arrangements for car wash locations. These leases will commence in years 2025 through 2027 with initial lease terms of 15 to 20 years.

Sale-leaseback Transactions

During the year ended December 31, 2025, we completed nine sale-leaseback transactions related to car wash locations with aggregate consideration of $48,423 resulting in a net loss of $12,057, which is included in loss on sale of assets, net in the consolidated statements of operations and comprehensive income. Contemporaneously with the closing of the sales, we entered into lease agreements for the properties for initial 20-year terms. For the sale-leaseback transactions consummated for the year ended December 31, 2025, the cumulative initial annual rents for the properties were approximately $2,873, subject to annual escalations. These leases are accounted for as operating leases.

During the year ended December 31, 2024, we completed 29 sale-leaseback transactions related to car wash locations with aggregate consideration of $134,912, resulting in a net loss of $8,862, which is included in loss on sale of assets, net in the consolidated statements of operations and comprehensive income. Contemporaneously with the closing of the sales, we entered into lease agreements for the properties for initial 20-year terms. For the sale-leaseback transactions consummated for the year ended December 31, 2024, the cumulative initial annual rents for the properties were approximately $8,887, subject to annual escalations. These leases are accounted for as operating leases.

10. Fair Value Measurements

The following table presents assets and liabilities which are measured at fair value on a recurring basis as of December 31, 2025:


	Fair Value Measurements
	Total		Level 1		Level 2		Level 3
Assets
Deferred compensation plan	$	7,464	$	7,464	$	—	$	—
Liabilities
Deferred compensation plan	$	4,675	$	4,675	$	—	$	—
Interest rate swap	$	234	$	—	$	234	$	—
Contingent consideration	$	1,933	$	—	$	—	$	1,933

The following table presents financial assets and liabilities which are measured at fair value on a recurring basis as of December 31, 2024:


	Fair Value Measurements
	Total		Level 1		Level 2		Level 3
Assets
Deferred compensation plan	$	6,487	$	6,487	$	—	$	—
Liabilities
Deferred compensation plan	$	4,425	$	4,425	$	—	$	—
Contingent consideration	$	4,328	$	—	$	—	$	4,328

We measure the fair value of our financial assets and liabilities using the highest level of inputs that are available as of the measurement date. The carrying amounts of cash and cash equivalents, accounts receivable, and accounts payable approximate their fair value due to the immediate or short-term maturity of these financial instruments. See Note 11 Interest Rate Swap for additional information on the interest rate swap.

We maintain a deferred compensation plan for a select group of our highly compensated employees, in which certain of our executive officers participate in. The plan allows eligible participants to defer up to 90% of their base salary and/or incentive plan compensation as well as any refunds from our 401(k) Plan. Participants may elect investment funds selected by the Company in whole percentages. Changes in the value of compensation deferred under these plans are recognized each period based on the fair value of the underlying measurement funds. These investment funds consist primarily of equity securities, such as common stock and mutual funds, and fixed income securities and are valued at the closing price reported on the active market on which the individual securities are traded and are classified as Level 1. These investment options do not represent actual ownership of or ownership rights in the applicable funds; they serve the purpose of valuing the account and the corresponding obligation of the Company.

As of December 31, 2025 and 2024, the fair value of our First Lien Term Loan approximated its carrying value due to the debt's variable interest rate terms.

As of December 31, 2025 and 2024, we did not hold any cash investments.

As of December 31, 2025 and 2024, we recognized a Level 3 contingent consideration liability in connection with the Downtowner Car Wash acquisition. We measured its contingent consideration liability arising from our 2021 acquisition using Level 3 unobservable inputs. The contingent consideration liability is associated with the achievement of certain targets and is estimated at each balance sheet date by considering among other factors, results of completed periods and our most recent financial projection for future periods subject to earn-out payments. There are two components to the contingent consideration: a payment when we obtained the certificate of occupancy for the car wash and it opened to the public in 2023 and an ongoing annual payment based on the achievement of certain financial metrics of the business. A change in the forecasted revenue could result in a significantly lower or higher fair value measurement. We determined that there were no significant changes to the unobservable inputs that would have resulted in a change in fair value of this contingent consideration liability at December 31, 2025. During the year ended December 31, 2025, $2,396 payment was made. During the year ended December 31, 2024, a payment of $422 was made.

During the years ended December 31, 2025 and 2024, there were no transfers between fair value measurement levels.

Employee Retirement Savings Plan

Retirement Benefits [Abstract]

Employee Retirement Savings Plan

15. Employee Retirement Savings Plan

In January 2011, we established a defined contribution 401(k)-plan to benefit certain employees. The 401(k)-plan sponsor is a wholly owned subsidiary of the Company. Employees are eligible to participate if they are at least 18 years of age and have worked for the Company for at least six months. We may make discretionary matching contributions. For the years ended December 31, 2025, 2024 and 2023, we made $1,483, $1,341, and $1,232, respectively, of matching contributions.

We maintain a nonqualified deferred compensation plan for certain management employees. Under the deferred compensation plan, a participant may elect to defer up to 90% of their base salary, 90% of their annual bonus, and/or 100% of 401(k) contributions that fail the top-heavy testing for highly compensated employees. We may make discretionary matching contributions. As of December 31, 2025 and 2024, the deferred compensation liability under this plan within accrued payroll and related expenses was $4,675 and $4,425, respectively.

Merger Agreement

On February 17, 2026, we entered into an Agreement and Plan of Merger (the “Merger Agreement”) with MCW Parent, LP, a Delaware limited partnership (“Parent”), Boson Merger Sub, Inc., a Delaware corporation and wholly owned subsidiary of Parent (“Merger Sub”, and together with Parent, the “Buyer Parties”), and, solely for purposes of the Borrower Provisions (as defined in the Merger Agreement), one of our wholly owned subsidiaries, Mister Car Wash Holdings, Inc. a Delaware corporation (“Borrower”), pursuant to which, on the terms and subject to the satisfaction or waiver of the conditions set forth therein, Merger Sub will be merged with and into the Company, with the Company continuing as the surviving corporation (the “Merger”). The Merger has been approved by the board of directors of the Company, acting upon the recommendation of a special committee of the board of directors consisting only of directors that the board of directors determined to each be a “disinterested director” (as defined in Section 144 of the General Corporation Law of the State of Delaware (the “DGCL”)) with respect to the transactions contemplated by the Merger Agreement.

If the Merger is completed, our common stock will no longer be listed on The Nasdaq Stock Market LLC and we will become a privately held company, owned by investment funds managed by Leonard Green & Partners, L.P. (“LGP”), and deregistered under the Securities and Exchange Act of 1934, as amended.

Pursuant to the terms of the Merger Agreement, neither Mister Car Wash, on the one hand, nor the Buyer Parties, on the other hand, are required to consummate the Merger prior to April 20, 2026. The Merger is expected to close in the first half of 2026.

Pursuant to the terms of the Merger Agreement, at the effective time of the Merger (the “Effective Time”), (i) each share of our common stock that is outstanding as of immediately prior to the Effective Time (other than shares of our common stock described in clauses (ii) or (iii) of this sentence) will be cancelled and extinguished and automatically converted into the right to receive cash in an amount per share equal to $7.00, without interest thereon (the “Per Share Price”), (ii) each share of our common stock that is (a) held by us as treasury stock or (b) owned by the Buyer Parties or any of their direct or indirect subsidiaries as of immediately prior to the Effective Time, including the shares of our common stock held by investment funds affiliated with LGP and the shares contributed to Parent by Company executives who execute a Management Rollover Agreement (as defined in the Merger Agreement), if any, will automatically be cancelled and extinguished without any conversion thereof or consideration paid therefor, and (iii) each share of our common stock that is issued and outstanding as of immediately prior to the Effective Time and held by any person or entity (including a “beneficial owner”) who has validly demanded and not validly withdrawn or otherwise lost its statutory appraisal rights in respect of such share in accordance with Section 262 of the DGCL (such shares, “Dissenting Company Shares”) will not be converted into, or represent the right to receive, the Per Share Price, and will instead be entitled to receive payment of the appraised value of such Dissenting Company Shares in accordance with the provisions of Section 262 of the DGCL.

Commitment Letter

Parent has obtained debt financing commitments for the purpose of financing the transactions contemplated by the Merger Agreement and paying related fees and expenses. Certain financial institutions have severally committed to provide Borrower with a $900 million senior secured first lien incremental term loan facility under the Credit Agreement, on the terms set forth in the related debt commitment letter. The obligations of such financial institutions to provide debt financing under the debt commitment letter are subject to a number of customary conditions. Pursuant to the Merger Agreement, the Company is required to provide Parent with customary cooperation in connection with the debt financing.

Segment Reporting [Abstract]

Segment Information

19. Segment Information

The Company operates as one operating segment where it derives its revenues from activities related to providing car wash services at its car wash locations that are geographically diversified throughout the United States and have similar economic characteristics and nature of services.

To assess consolidated performance the chief operating decision maker (“CODM”), who is the Chief Executive Officer, evaluates the operating results and performance through net income. Our CODM regularly reviews net income as reported on the consolidated statement of operations and total assets as reported on the consolidated balance sheet for purposes of evaluating performance, allocating resources, setting incentive compensation targets, and planning and forecasting future periods. As presented on the consolidated statements of operations and comprehensive income, the CODM views consolidated expense information related to the cost of labor and chemicals, other store operating expenses, and general and administrative expenses to be significant and there are no other significant segment expenses or items that would require disclosure.

- Definition

The entire disclosure for reporting segments including data and tables. Reportable segments include those that meet any of the following quantitative thresholds a) it's reported revenue, including sales to external customers and intersegment sales or transfers is 10 percent or more of the combined revenue, internal and external, of all operating segments b) the absolute amount of its reported profit or loss is 10 percent or more of the greater, in absolute amount of 1) the combined reported profit of all operating segments that did not report a loss or 2) the combined reported loss of all operating segments that did report a loss c) its assets are 10 percent or more of the combined assets of all operating segments.

Business Combination [Abstract]

Business Combinations

16. Business Combinations

From time to time, we may pursue acquisitions of conveyorized car washes that either strategically fit with the business or expand our presence in new and attractive markets.

We account for business combinations under the acquisition method of accounting. The assets acquired, and liabilities assumed in connection with business acquisitions are recorded at the date of acquisition at their estimated fair values, with any excess of the purchase price over the estimated fair values of the net assets acquired and intangible assets assigned, recorded as goodwill. Significant judgment is required in estimating the fair value of assets acquired and liabilities assumed and in assigning their respective useful lives. Accordingly, we may engage third-party valuation specialists to assist in these determinations. The fair value estimates are based on available historical information and on future expectations and assumptions deemed reasonable by management; but are inherently uncertain.

The consolidated financial statements reflect the operations of an acquired business starting from the effective date of the acquisition. We expensed $323, $0 and $208 of acquisition-related costs for the years ended December 31, 2025, 2024 and 2023, respectively. These acquisition-related costs are expensed as incurred and are included in general and administrative expenses in the accompanying consolidated statements of operations and comprehensive income.

For both years ended December 31, 2025 and 2024, the amount of acquired goodwill that is not deductible for income tax purposes was $0. The goodwill recognized in 2025 was primarily attributable to the expected synergies to be achieved from the business combinations.

2025 Acquisitions

For the year ended December 31, 2025, we acquired the assets and liabilities of five conveyorized car washes in one acquisition. The transaction was for an immaterial amount of cash consideration, and we do not believe the acquisition is material to our overall consolidated financial statements. The cash consideration for the transaction is included in purchases of property and equipment in the investing activities on face of the statement of cash flows.


Location (Seller)	Number of Washes	Month Acquired
Texas (Whistle Express)	5	October

2024 Acquisitions

For the year ended December 31, 2024, we did not consummate any acquisitions.

Cybersecurity Risk Management, Strategy, and Governance [Line Items]
Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	Item 1C. Cybersecurity Risk Management and Strategy As a component of our overall risk management system and processes, we have a risk-based cybersecurity program, dedicated to protecting our data as well as data belonging to consumers (including UWC Members), employees and suppliers. We devote significant resources and utilize a defensive in-depth strategy, with multiple layers of security controls to protect the security of our computer systems, software, networks, and other technology assets. Our security efforts are designed to preserve the confidentiality, integrity, and continued availability of all information we own, or is in our care, and protect against, among other things, cybersecurity attacks by unauthorized parties attempting to obtain access to confidential information, destroy data, disrupt or degrade service, sabotage systems, or cause other damage. These processes include technical, administrative and physical controls and processes, as well as contractual mechanisms to mitigate risk. We also have policies and procedures to oversee and identify the cybersecurity risks associated with our use of third-party service providers, including the regular review of System & Organization Controls (“SOC”) reports, relevant cyber attestations, and other independent cyber ratings. Through a combination of governance, risk, and compliance (GRC) resources, we • proactively monitor IT controls to ensure compliance with legal and regulatory requirements, • perform third-party risk management assessments, • implement processes designed to ensure essential business functions remain available during business disruptions, • develop and update incident response plans to address potential weaknesses, and • maintain cyber incident management and reporting procedures. These processes are overseen by our Chief Technology Officer, who has over 30 years of experience consulting and leading technology teams at several global multi-unit brands, including Blockbuster, FedEx, and Yum! Brands. Our systems are periodically the target of directed attacks intended to lead to interruptions and delays in our service and operations as well as loss, misuse or theft of personal information (of third parties, employees, and our customers) and other data, confidential information or intellectual property. However, to date, we are not aware of any incident or cybersecurity risks having a material impact on our business, results of operations or financial condition. Board Oversight and Governance Our Board recognizes the important role of information security and mitigating cybersecurity and other data security threats. While the full Board has overall responsibility for risk oversight, it is supported in this function primarily by its committees. The Audit Committee is responsible for reviewing and discussing our policies with respect to risk assessment and risk management, including risks related to cybersecurity and other technology issues. The Board periodically evaluates our cybersecurity strategy to help ensure its effectiveness. Management provides periodic reports to the Audit Committee regarding cybersecurity and other information technology risks, as well as our plans to mitigate cybersecurity risks and to respond to any breaches, and to the Nominating and Corporate Governance Committee regarding governance matters related to cybersecurity and other information technology risks.

Stock-Based Compensation

12 Months Ended

Dec. 31, 2025

Share-Based Payment Arrangement [Abstract]

Stock-Based Compensation

14. Stock-Based Compensation

The 2014 Plan

Under the 2014 Stock Option Plan of Hotshine Holdings, Inc. (the “2014 Plan”), the Company may grant incentive stock options or nonqualified stock options to purchase common shares of the Company to its employees, directors, officers, outside advisors and non-employee consultants.

All stock options granted under the 2014 Plan are equity-classified and have a contractual life of ten years. Under the 2014 Plan, 60% of the shares in a grant contain service-based vesting conditions and vest ratably over a five-year period and 40% of the shares in a grant contain performance-based vesting conditions (“Performance Vesting Options”).

The 2021 Plan

In June 2021, the Board adopted the 2021 Incentive Award Plan (the “2021 Plan”), which was subsequently approved by the Company's stockholders and became effective on June 25, 2021. Under the 2021 Plan, the Company may grant incentive stock options, nonqualified stock options, restricted stock units (“RSUs”), restricted stock, and other stock- or cash-based awards to its employees, directors, officers, and non-employee consultants. Initially, the maximum number of shares of the Company’s common stock that may be issued under the 2021 Plan is 29,800,000 new shares of common stock, which includes 256,431 shares of common stock that remained available for issuance under the 2014 Plan at June 25, 2021. Any shares of common stock subject to outstanding stock awards granted under the 2014 Plan and, following June 25, 2021, terminate, expire or are otherwise forfeited, reacquired or withheld will become available for issuance under the 2021 Plan.

All stock options granted under the 2021 Plan are equity-classified and have a contractual life of ten years. Under the 2021 Plan, the stock options contain service-based vesting conditions and generally vest ratably over a three- to five-year period (collectively with stock options under the 2014 Plan, the “Time Vesting Options”). The exercise prices for stock options granted under the 2021 Plan were not less than the fair market value of the common stock of the Company on the date of grant.

RSUs granted under the 2021 Plan are equity-classified and contain service-based conditions and generally vest ratably over one- to five-year periods. Each RSU represents the right to receive one share of the Company’s common stock upon vesting. The fair value is calculated based upon the Company’s closing stock price on the date of grant, and the stock-based compensation expense is recognized over the requisite service period, which is generally the vesting period.

The 2021 ESPP

In June 2021, the Board adopted the 2021 Employee Stock Purchase Plan (“2021 ESPP”), which was subsequently approved by the Company’s stockholders and became effective in June 2021. The 2021 ESPP authorizes the initial issuance of up to 5,000,000 shares of the Company’s common stock to eligible employees of the Company or, as designated by the Board, employees of a related company. The 2021 ESPP provides for offering periods not to

exceed 27 months, and each offering period will include purchase periods. The Company determined that offering periods would commence at approximately the six-month period beginning with an enrollment date and ending with the next exercise date.

The 2021 ESPP provides that the number of shares reserved and available for issuance under the 2021 ESPP will automatically increase on January 1 of each calendar year from January 1, 2022 through January 1, 2031 by an amount equal to the lesser of (i) 0.5% of the outstanding number of shares of common stock on the immediately preceding December 31 and (ii) such lesser number of shares of common stock as determined by the Board.

Share-Based Payment Valuation

The grant date fair value of Time Vesting Options granted and stock purchase rights granted under the 2021 ESPP are determined using the Black-Scholes option-pricing model.
