Commitments and Contingencies

11. Commitments and Contingencies

Lease Commitments

The Company has operating leases for certain operating facilities, vehicles and equipment, which provide the right to use the underlying asset and require lease payments over the term of the lease. Each new contract is evaluated to determine if an arrangement contains a lease and whether that lease meets the classification criteria of a finance or operating lease. All identified leases are recorded on the Consolidated Balance Sheets with a corresponding operating lease right-of-use asset, net, representing the right to use the underlying asset for the lease term and the operating lease liabilities representing the obligation to make lease payments arising from the lease. Short-term operating leases, which have an initial term of twelve months or less, are not recorded on the Consolidated Balance Sheets.

Operating lease right-of-use assets, net and operating lease liabilities are recognized at the commencement date of the lease based on the present value of lease payments over the lease term and include options to extend or terminate the lease when they are reasonably certain to be exercised. The present value of lease payments is determined primarily by using the incremental borrowing rate based on the information available as of the lease commencement date. Lease expense for operating leases is recorded on a straight-line basis over the lease term and variable lease costs are recorded as incurred. Both lease expense and variable lease costs are primarily recorded in cost of revenues on the Company's Consolidated Statements of Income. The Company's lease agreements do not contain any material residual value guarantees or material restrictive covenants.

The following table presents the operating lease cost and information related to the operating lease right-of-use assets, net and operating lease liabilities for fiscal 2024, 2023 and 2022:


(In thousands, except lease term and discount rate)	2024			2023			2022
Lease cost:
Operating lease costs including short-term lease expense and variable lease costs, which were immaterial in the period	$	25,866		$	22,303		$	20,284

Operating cash flow impacts:
Cash paid for amounts included in the measurement of operating lease liabilities	$	20,083		$	16,710		$	15,123
Operating lease right-of-use assets obtained in exchange for new operating lease liabilities	$	19,511		$	23,076		$	21,391

Weighted average remaining lease term - operating leases	4.7			4.48			4.66
Weighted average discount rate - operating leases		4.74	%		3.55	%		2.24	%

Total rent expense on all leases was $21.8 million, $18.4 million and $16.7 million for fiscal 2024, 2023 and 2022, respectively.

The contractual future minimum lease payments of the Company's operating lease liabilities by fiscal year as of August 31, 2024 are as follows (in thousands):

Environmental and Legal Contingencies

The Company and its operations are subject to various federal, state and local laws and regulations governing, among other things, air emissions, wastewater discharges, and the generation, handling, storage, transportation, treatment and disposal of hazardous wastes and other substances. In particular, industrial laundries currently use and must properly dispose of detergent

wastewater and other residues, and, in the past, used perchloroethylene and other dry-cleaning solvents. The Company is attentive to the environmental concerns surrounding the disposal of these materials and has, through the years, taken measures to avoid their improper disposal. The Company has settled, or contributed to the settlement of, past actions or claims brought against the Company relating to the disposal of hazardous materials at several sites and there can be no assurance that the Company will not have to expend material amounts to remediate the consequences of any such disposal in the future.

U.S. GAAP requires that a liability for contingencies be recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated. Significant judgment is required to determine the existence of a liability, as well as the amount to be recorded. The Company regularly consults with attorneys and outside consultants in its consideration of the relevant facts and circumstances before recording a contingent liability. Changes in enacted laws, regulatory orders or decrees, management’s estimates of costs, risk-free interest rates, insurance proceeds, participation by other parties, the timing of payments, the input of the Company’s attorneys and outside consultants or other factual circumstances could have a material impact on the amounts recorded for environmental and other contingent liabilities.

Under environmental laws, an owner or lessee of real estate may be liable for the costs of removal or remediation of certain hazardous or toxic substances located on, or in, or emanating from, such property, as well as related costs of investigation and property damage. Such laws often impose liability without regard to whether the owner or lessee knew of, or was responsible for the presence of such hazardous or toxic substances. There can be no assurances that acquired or leased locations have been operated in compliance with environmental laws and regulations or that future uses or conditions will not result in the imposition of liability upon the Company under such laws or expose the Company to third-party actions such as tort suits. The Company continues to address environmental conditions under terms of consent orders negotiated with the applicable environmental authorities or otherwise with respect to certain sites.

The Company has accrued certain costs related to certain sites, including but not limited to, sites in Woburn and Somerville, Massachusetts, as it has been determined that the costs are probable and can be reasonably estimated. The Company, together with multiple other companies, is party to a consent decree related to the Company’s property and parcels of land (the “Central Area”) at a site in Woburn, Massachusetts. The United States Environmental Protection Agency (the “EPA”) has provided the Company and other signatories to the consent decree with comments on the design and implementation of groundwater and soil remedies at the Woburn site and investigation of environmental conditions in the Central Area. The consent decree does not address any remediation work that may be required in the Central Area. The Company, together with other signatories, has implemented and proposed to do additional work at the Woburn site but many of the EPA’s comments remain to be resolved. The Company has accrued costs to perform certain work responsive to the EPA’s comments. Additionally, the Company has implemented mitigation measures and continues to monitor environmental conditions at a site in Somerville, Massachusetts. The Company has agreed to undertake additional actions responsive to a notice of audit findings from the Massachusetts Department of Environmental Protection concerning a regulatory submittal that the Company made in 2009 for a portion of the site. The Company has received demands from the local transit authority for reimbursement of certain costs associated with its construction of a new municipal transit station in the area of the Somerville site. This station was part of an extension of the local transit system. The Company has reserved for costs in connection with this matter; however, in light of the uncertainties associated with this matter, these costs and the related reserve may change.

The Company routinely reviews and evaluates sites that may require remediation and monitoring and determines its estimated costs based on various estimates and assumptions. These estimates are developed using its internal sources or by third party environmental engineers or other service providers. Internally developed estimates are based on:

•

Management’s judgment and experience in remediating and monitoring the Company’s sites;

•

Information available from regulatory agencies as to costs of remediation and monitoring;

•

The number, financial resources and relative degree of responsibility of other potentially responsible parties (“PRPs”) who may be liable for remediation and monitoring of a specific site; and

•

The typical allocation of costs among PRPs.

There is usually a range of reasonable estimates of the costs associated with each site. In accordance with U.S. GAAP, the Company’s accruals reflect the amount within the range that it believes is the best estimate or the low end of a range of estimates if no point within the range is a better estimate. Where it believes that both the amount of a particular liability and the timing of the payments are reliably determinable, the Company adjusts the cost in current dollars using a rate of 3% for inflation until the time of expected payment and discounts the cost to present value using current risk-free interest rates. As of August 31, 2024, the risk-free interest rates utilized by the Company ranged from 4.2% to 4.3%.

For environmental liabilities that have been discounted, the Company includes interest accretion, based on the effective interest method, in selling and administrative expenses on the accompanying Consolidated Statements of Income.

The changes to the Company’s environmental liabilities for fiscal 2024 and 2023 are as follows (in thousands):


Year ended	August 31, 2024			August 26, 2023
Beginning balance	$	30,029		$	32,191
Costs incurred for which reserves have been provided		(3,176	)		(1,936	)
Insurance proceeds		238			147
Interest accretion		1,264			1,036

Ending balance	$	31,255		$	30,029

Anticipated payments and insurance proceeds of currently identified environmental remediation liabilities as of August 31, 2024, for the next five fiscal years and thereafter, as measured in current dollars, are reflected below (in thousands):


Fiscal year ended August	2025			2026			2027			2028			2029			Thereafter			Total
Estimated costs—current dollars	$	14,425		$	2,836		$	1,527		$	1,280		$	997		$	15,047		$	36,112
Estimated insurance proceeds		(180	)		(195	)		(159	)		(173	)		(9	)		(230	)		(946	)
Net anticipated costs	$	14,245		$	2,641		$	1,368		$	1,107		$	988		$	14,817		$	35,166
Effect of inflation																				9,501
Effect of discounting																				(13,412	)
Balance as of August 31, 2024																			$	31,255

Estimated insurance proceeds are primarily obtained from an annuity received as part of a legal settlement with an insurance company. Annual proceeds of approximately $0.3 million are deposited into an escrow account which funds remediation and monitoring costs for two sites related to former operations in Williamstown, Vermont. Annual proceeds received but not expended in the current year accumulate in this account and may be used in future years for costs related to this site through the year 2027. As of August 31, 2024, the balance in this escrow account, which is held in a trust and is not recorded in the Company’s accompanying Consolidated Balance Sheets, was approximately $5.6 million. Also included in estimated insurance proceeds are amounts the Company is entitled to receive pursuant to legal settlements as reimbursements from three insurance companies for estimated costs at one of its sites.

The Company’s nuclear garment decontamination facilities are licensed by respective state agencies, as delegated authority by the Nuclear Regulatory Commission (the “NRC”) pursuant to the NRC’s Agreement State program and are subject to applicable federal and state radioactive material regulations. In addition, the Company’s international locations (Canada, the United Kingdom and the European Union) are regulated by equivalent respective jurisdictional authorities. There can be no assurance that such regulation will not lead to material disruptions in the Company’s garment decontamination business.

From time to time, the Company is also subject to legal and regulatory proceedings and claims arising from the conduct of its business operations, including personal injury claims, customer contract matters, employment claims and environmental matters as described above.

In addition, in the fourth quarter of fiscal 2022, the Mexican federal tax authority issued a tax assessment on the Company’s subsidiary in Mexico for fiscal 2016 import taxes, value added taxes and custom processing fees of over $17.0 million, plus surcharges, fines and penalties of over $67.7 million for a total assessment of over $84.7 million. The Company challenged the validity of the tax assessment through an appeal process. In the first quarter of fiscal 2025, the Federal Tax Court in Mexico made a determination partially in its favor. Following the Federal Tax Court’s determination, the Company filed a constitutional action before the Federal Administrative Court. While the Company is unable to ascertain the ultimate outcome of this matter, based on the information currently available, the Company believes that a loss with respect to this matter is neither probable nor remote. Given the uncertainty associated with the ultimate resolution of this matter, the Company is unable to reasonably assess an estimate or range of estimates of any potential losses.

While it is impossible for the Company to ascertain the ultimate legal and financial liability with respect to contingent liabilities, including lawsuits and environmental contingencies, the Company believes that the aggregate amount of such liabilities, if any, in excess of amounts covered by insurance have been properly accrued in accordance with U.S. GAAP. It is

possible, however, that the future financial position and/or results of operations for any particular future period could be materially affected by changes in the Company’s assumptions or strategies related to these contingencies or changes out of the Company’s control.

Other Contingent Liabilities

As security for certain agreements with the NRC and various state agencies related to the nuclear operations (see above) and certain insurance programs, the Company had standby irrevocable bank commercial letters of credit of $65.1 million and $66.5 million outstanding as of August 31, 2024 and August 26, 2023, respectively.

Non-cancellable purchase commitments for inventories, software, and services amounted to $91.2 million as of August 31, 2024, of which $58.4 million will be paid in less than 1 year, $21.1 million will be paid in 1 to 3 years, and the remaining will be paid in 3 to 5 years.

Goodwill and Other Intangible Assets

8. Goodwill and Other Intangible Assets

When the Company acquires a business, the amount assigned to the tangible assets and liabilities and intangible assets acquired is based on their respective fair values determined as of the acquisition date. The excess of the purchase price over the tangible assets and liabilities and intangible assets is recorded as goodwill. The Company does not amortize goodwill, but it is reviewed annually or more frequently if certain indicators arise, for impairment. There were no impairment losses related to goodwill or intangible assets during fiscal 2024, 2023 and 2022.

The changes in the carrying amount of goodwill are as follows (in thousands):


Balance as of August 27, 2022	$	457,259
Purchase price adjustments recorded during the period		190,777
Other		(136	)
Balance as of August 26, 2023	$	647,900
Purchase price adjustments recorded during the period		900
Other		50

Income Taxes

4. Income Taxes

The provision for income taxes consists of the following (in thousands):


Year ended	2024		2023		2022
Current:
Federal	$	30,932	$	7,269	$	7,655
Foreign		1,231		2,519		1,839
State		6,007		2,695		3,701
Total current	$	38,170	$	12,483	$	13,195

Deferred:
Federal	$	4,027	$	19,227	$	13,883
Foreign		1,269		568		180
State		439		2,885		3,663
Total deferred	$	5,735	$	22,680	$	17,726
Total provision for income taxes	$	43,905	$	35,163	$	30,921

The following table reconciles the provision for income taxes using the statutory federal income tax rate to the actual provision for income taxes:


Year ended	2024			2023			2022
Income taxes at the statutory federal income tax rate		21.0	%		21.0	%		21.0	%
State income taxes		3.6			3.8			4.7
Adjustments to tax reserve		(0.5	)		0.8			(2.1	)
Other		(0.9	)		(0.3	)		(0.6	)
Effective income tax rate		23.2	%		25.3	%		23.0	%

The decrease in the effective tax rate for fiscal 2024 as compared to the corresponding period in the prior fiscal year was due primarily to favorable adjustments to our tax reserves during the current period and the remeasurement of U.S. net deferred tax liabilities because of legislative changes enacted during the current period impacting the Company’s state tax rate.

The components of deferred income taxes included on the Consolidated Balance Sheets are as follows (in thousands):


	August 31, 2024		August 26, 2023
Deferred tax assets:
Payroll and benefit related	$	16,009	$	15,284
Insurance related		14,067		14,347
Environmental		7,807		7,542
Accrued expenses		8,169		7,847
Operating lease liabilities		17,083		16,162
Research and development		6,243		3,628
Other		12,884		11,916
Total deferred tax assets	$	82,262	$	76,726

Deferred tax liabilities:
Payroll and benefit related	$	24,655	$	22,230
Tax in excess of book depreciation		59,113		53,597
Purchased intangible assets		48,908		43,994
Rental merchandise in service		59,692		62,562
Operating lease right-of-use assets		16,575		15,600
Other		320		488
Total deferred tax liabilities		209,263		198,471
Net deferred tax liability	$	127,001	$	121,745

The Company regularly reviews deferred tax assets for recoverability based upon projected future taxable income and the expected timing of the reversals of existing temporary differences. Although realization is not assured, management believes it is more likely than not that the recorded deferred tax assets will be realized.

Foreign tax effect

As of August 31, 2024, unremitted foreign earnings have been retained by the Company’s foreign subsidiaries for indefinite reinvestment. If the Company were to repatriate those earnings, in the form of dividends or otherwise, the Company could be subject to immaterial withholding taxes payable to the various foreign countries.

In October 2021, the Organization for Economic Co-operation and Development (“OECD”) introduced an inclusive framework to address tax challenges arising from the digitalization of the economy through a two-pillar solution. One of the components of the solution is the implementation of a global minimum corporate tax rate of 15% for large multinational corporations (“Pillar Two”). The OECD continues to release additional guidance on the two-pillar solution with implementation to begin in 2024 while reporting of the tax applicable will not occur until 2026. Based on currently enacted guidelines, the Company does not expect Pillar Two to have a material impact upon its tax expense, cash taxes, and effective tax rate.

Uncertain tax positions

As of August 31, 2024 and August 26, 2023, there was $4.6 million and $7.8 million, respectively, of unrecognized tax benefits, of which $4.5 million and $7.1 million, respectively, would favorably impact the Company’s effective tax rate, if recognized. The Company recognized interest and penalties related to uncertain tax positions as a component of income tax expense which is consistent with the recognition of these items in prior reporting periods. As of August 31, 2024 and August 26, 2023, the Company had accrued a nominal amount in interest and penalties, in its long-term accrued liabilities. For fiscal 2024, 2023 and 2022, the Company recognized a nominal expense in its Consolidated Statements of Income related to interest and penalties.

A reconciliation of the beginning and ending amount of unrecognized tax benefits are as follows (in thousands):


Balance at August 27, 2022	$	6,417
Additions based on tax positions related to the current year		1,042
Additions for tax positions of prior years		840
Reduction for tax positions of prior years		(219	)
Statute expirations		(329	)
Balance at August 26, 2023		7,751
Additions based on tax positions related to the current year		1,069
Additions for tax positions of prior years		142
Reduction for tax positions of prior years		(4,257	)
Statute expirations		(67	)
Balance at August 31, 2024	$	4,638

The Company has a significant portion of its operations in the U.S. and Canada. It is required to file federal income tax returns as well as state income tax returns in a majority of the U.S. states and also in a number of Canadian provinces. At times, the Company is subject to audits in these jurisdictions, which typically are complex and can require several years to resolve. The final resolution of any such tax audits could result in either a reduction in the Company’s accruals or an increase in its income tax provision, both of which could have a material impact on the consolidated results of operations in any given period.

All U.S. and Canadian federal income tax statutes have lapsed for filings up to and including fiscal years 2019 and 2016, respectively. With a few exceptions, the Company is no longer subject to state and local income tax examinations for periods prior to fiscal 2020. The Company is not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will change significantly in the next 12 months.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Typical customers for these specialized services include government agencies, research and development laboratories, high technology companies and utility providers operating nuclear reactors.

As discussed and described in Note 15, “Segment Reporting”, to these Consolidated Financial Statements, the Company has five reporting segments: United States (“U.S.”) and Canadian Rental and Cleaning, Manufacturing (“MFG”), Specialty Garments Rental and Cleaning (“Specialty Garments”), First Aid and Corporate. The operations of the U.S. and Canadian Rental and Cleaning reporting segment are referred to by the Company as its “industrial laundry operations” and the locations related to this reporting segment are referred to as “industrial laundries”. The Company refers to its U.S. and Canadian Rental and Cleaning, MFG, and Corporate segments combined as its “Core Laundry Operations”.

The Consolidated Financial Statements include the accounts of the Company and its subsidiaries, all of which are wholly-owned. Intercompany balances and transactions are eliminated in consolidation.

Basis of Presentation

The Consolidated Financial Statements included herein have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). There have been no material changes in the accounting policies followed by the Company during the current fiscal year other than the adoption of recent accounting pronouncements as discussed in greater detail in the Recent Accounting Pronouncements sub-section of this Note.

Use of Estimates

The preparation of these Consolidated Financial Statements is in conformity with U.S. GAAP which requires management to make estimates and assumptions that affect the reported amounts in the financial statements and accompanying notes. The Company utilizes key estimates in preparing the financial statements including casualty and environmental estimates, valuation of intangible assets acquired in a business combination, recoverability of goodwill, intangibles, income taxes and long-lived assets. These estimates are based on historical information, current trends, and information available from other sources. The Company’s results are affected by economic, political, legislative, regulatory and legal actions. Economic conditions, such as recessionary trends, inflation, interest and monetary exchange rates, government fiscal policies, and changes in the prices of raw materials, can have a significant effect on operations. These factors and other events could cause actual results to differ from management's estimates.

Fiscal Year

The Company’s fiscal year ends on the last Saturday in August. For financial reporting purposes, fiscal year ended August 31, 2024 (“fiscal 2024”) consisted of 53 weeks, and fiscal years ended August 26, 2023 (“fiscal 2023”) and August 27, 2022 (“fiscal 2022”) both consisted of 52 weeks. The additional week was included in the fourth quarter of fiscal 2024.

Cash, Cash Equivalents and Short-Term Investments

Cash, cash equivalents and short-term investments include cash in banks, money market securities and bank short-term investments having original maturities of six months or less. As of August 31, 2024 and August 26, 2023, the Company had $13.5 million and $10.2 million in short-term investments, respectively.

Accounts receivable

Accounts receivable represents amounts due from customers and is presented net of reserves for expected credit losses. The Company utilizes its judgment and estimates are used in determining the collectability of accounts receivable and evaluating the adequacy of the reserve for expected credit losses. The Company considers specific accounts receivable and historical credit loss experience, customer credit worthiness, current economic trends and the age of outstanding balances as part of its evaluation. When an account is considered uncollectible, it is written off against the reserve for expected credit losses.

The following table presents the change in the allowance for credit losses, which is included in Receivables, net of reserves on the Consolidated Balance Sheets as of August 31, 2024 and August 26, 2023 are as follows (in thousands):


(In thousands)	August 31, 2024			August 26, 2023
Beginning balance	$	6,276		$	5,930
Current period provision		13,976			10,740
Write-offs and other		(12,336	)		(10,394	)
Ending balance	$	7,916		$	6,276

Financial Instruments

The Company’s financial instruments, which may expose the Company to concentrations of credit risk, include cash and cash equivalents, receivables, accounts payable and foreign exchange forward contracts. Each of these financial instruments is recorded at cost, which approximates its fair value given the short maturity of each financial instrument.

Revenue Recognition

In fiscal 2024, approximately 84.2% of the Company’s revenues are derived from fees for route servicing of Core Laundry Operations, Specialty Garments and First Aid services performed by the Company’s employees at the customer’s location of business. Revenues from the Company’s route servicing customer contracts represent a single-performance obligation. The Company recognizes these revenues over time as services are performed based on the nature of services provided and contractual rates (input method). Certain of the Company’s customer contracts, primarily within the Company’s Core Laundry Operations, include pricing terms and conditions that include components of variable consideration. The variable consideration is typically in the form of consideration due to a customer based on performance metrics specified within the contract. Specifically, some contracts contain discounts or rebates that the customer can earn through the achievement of specified volume levels. Each component of variable consideration is earned based on the Company’s actual performance during the measurement period specified within the contract. To determine the transaction price, the Company estimates the variable consideration using the most likely amount method, based on the specific contract provisions and known performance results during the relevant measurement period.

When determining if variable consideration should be constrained, the Company considers whether factors outside its control could result in a significant reversal of revenue. In making these assessments, the Company considers the likelihood and magnitude of a potential reversal. The Company’s performance period generally corresponds with the monthly invoice period. No significant constraints on the Company’s revenue recognition were applied during fiscal 2024, 2023 and 2022. The Company reassesses these estimates during each reporting period.

The Company maintains a liability for these discounts and rebates within accrued liabilities on the Consolidated Balance Sheets. Variable consideration also includes consideration paid to a customer at the beginning of a contract. The Company capitalizes this consideration and amortizes it over the life of the contract as a reduction to revenue in accordance with the accounting guidance for revenue recognition. These assets are included in other assets on the Consolidated Balance Sheets.

The following table presents the Company’s revenues for fiscal 2024, 2023 and 2022 disaggregated by service type:


	Year ended
	2024					2023					2022
(In thousands, except percentages)	Revenues		% of Revenues			Revenues		% of Revenues			Revenues		% of Revenues

See Note 15, “Segment Reporting” for additional details of segment definitions.

Costs to Obtain a Contract

The Company defers commission expenses paid to its employee-partners when the commissions are deemed to be incremental for obtaining the route servicing customer contract. The deferred commissions are amortized on a straight-line basis over the expected period of benefit. The Company reviews the deferred commission balances for impairment on an ongoing basis. Deferred commissions are classified as current or non-current based on the timing of when the Company expects to recognize the expense.

The following table presents deferred commissions on the Company's Consolidated Balance Sheets as of August 31, 2024 and August 26, 2023 are as follows (in thousands):


Balance Sheet Location	August 31, 2024		August 26, 2023
Prepaid expenses and other current assets	$	18,079	$	16,495
Other assets		78,856		70,393

The following table presents the Company's amortization expense related to deferred commissions on the Consolidated Statements of Income for fiscal 2024, 2023 and 2022 are as follows (in thousands):


Income Statement Location	2024		2023		2022
Selling and administrative expenses	$	18,031	$	16,500	$	15,400

Inventories and Rental Merchandise in Service

nventories and Rental Merchandise in Service

Inventories are stated at the lower of cost or net realizable value, net of any reserve for excess and obsolete inventory. Work-in-process and finished goods inventories consist of materials, labor and manufacturing overhead. Judgments and estimates are used in determining the likelihood that new goods on hand can be sold to customers or used in rental operations. Historical inventory usage and current revenue trends are considered in estimating both excess and obsolete inventories. If actual product demand and market conditions are less favorable than those projected by management, additional inventory write-downs may be required. The Company uses the first-in, first-out (“FIFO”) method to value its inventories.

The components of inventory as of August 31, 2024 and August 26, 2023 are as follows (in thousands):


	August 31, 2024		August 26, 2023
Raw materials	$	22,164	$	25,147
Work in process		2,832		4,444
Finished goods		131,912		118,743
Total inventory	$	156,908	$	148,334

Rental merchandise in service is amortized, primarily on a straight-line basis, over the estimated service lives of the merchandise, which range from six to thirty-six months. The amortization expense is included in the cost of revenues on the Company’s Consolidated Statements of Income. In establishing estimated lives for merchandise in service, management considers historical experience and the intended use of the merchandise. Material differences may result in the amount and timing of operating profit for any period if management makes significant changes to these estimates.

Property, Plant and Equipment

Property, plant and equipment are recorded at cost. Expenditures for maintenance and repairs are expensed as incurred, while expenditures for renewals and betterments are capitalized.

The components of property, plant and equipment as of August 31, 2024 and August 26, 2023 are as follows (in thousands):


	August 31, 2024		August 26, 2023
Land, buildings and leasehold equipment	$	787,628	$	744,085
Machinery and equipment		710,108		676,490
Motor vehicles		372,837		331,537
Total property, plant and equipment, gross		1,870,573		1,752,112
Less: accumulated depreciation		1,068,961		995,572
Total property, plant and equipment, net	$	801,612	$	756,540

The Company provides for depreciation on the straight-line method based on the date the asset is placed in service using the following estimated useful lives:


Buildings (in years)		30 — 40
Building components (in years)		10 — 20
Leasehold improvements		Shorter of useful life or term of lease
Machinery and equipment (in years)		3 — 10
Motor vehicles (in years)		3 — 5

Long-lived assets, including property, plant and equipment, are evaluated for impairment whenever events or circumstances indicate an asset may be impaired. There were no material impairments of long-lived assets in fiscal 2024, 2023 and 2022.

Goodwill and Other Intangible Assets

In accordance with U.S. GAAP, the Company does not amortize goodwill. Instead, the Company tests goodwill for impairment on an annual basis. Management completes its annual goodwill impairment test on the first day of the fourth quarter of each fiscal year. In addition, U.S. GAAP requires that companies test goodwill if events occur or circumstances change that would more likely than not reduce the fair value of a reporting unit to which goodwill is assigned below its

carrying amount. The Company used both the qualitative and quantitative assessment options for its impairment testing for goodwill in fiscal 2024 and determined that the fair values of the reporting units more likely than not exceeded their carrying values and that there was no evidence of impairment as of May 26, 2024.

The Company cannot predict future economic conditions and their impact on the Company or the future net realizable value of the Company’s stock. A decline in the Company’s market capitalization and/or deterioration in general economic conditions could negatively and materially impact the Company’s assumptions and assessment of the fair value of the Company’s business. If general economic conditions or the Company’s financial performance deteriorate, the Company may be required to record a goodwill impairment charge in the future which could have a material impact on the Company’s financial condition and results of operations.

Definite-lived intangible assets are amortized over their estimated useful lives, which are based on management’s estimates of the period that the assets will generate economic benefits. Definite-lived intangible assets are evaluated for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable in accordance with U.S. GAAP. There were no impairments of goodwill or indicators of impairment for definite-lived intangible assets in fiscal 2024, 2023 or 2022.

As of August 31, 2024, definite-lived intangible assets have a weighted average useful life of approximately 12.9 years. Customer contracts have a weighted average useful life of approximately 14.6 years and other intangible assets, net, which consist of primarily of restrictive covenants, software and trademarks, have a weighted average useful life of approximately 8.5 years.

Cloud Computing Arrangements

The Company enters into certain cloud-based software hosting arrangements that are accounted for as service contracts. Costs incurred for these arrangements are capitalized for application development activities, if material, and immediately expensed for preliminary project activities and post-implementation activities. The Company amortizes the capitalized development costs straight-line over the fixed, non-cancellable term of the associated hosting arrangement plus any reasonably certain renewal periods. The capitalized costs are included in “Prepaid expenses and other current assets” and “Long-term other assets” on the Company's Consolidated Balance Sheets. Capitalized costs were $18.9 million and $2.2 million as of August 31, 2024, and August 26, 2023, respectively. The Company has not placed any modules of the applicable software in service as of August 31, 2024.

Cloud Computing Arrangements

Environmental and Other Contingencies

The Company is subject to legal proceedings and claims arising from the conduct of its business operations, including but not limited to, environmental matters, personal injury, customer contract matters and employment claims. U.S. GAAP require that a liability for contingencies be recorded when it is probable that a liability has occurred and the amount of the liability can be reasonably estimated. Significant judgment is required to determine the existence of a liability, as well as the amount to be recorded. The Company regularly consults with attorneys and outside consultants in its consideration of the relevant facts and circumstances before recording a contingent liability. The Company records accruals for environmental and other contingencies based on enacted laws, regulatory orders or decrees, the Company’s estimates of costs, insurance proceeds, participation by other parties, the timing of payments, and the input of outside consultants and attorneys.

The estimated liability for environmental contingencies has been discounted as of August 31, 2024 using risk-free interest rates ranging from 4.2% to 4.3% over periods ranging from twenty to thirty years. The estimated current costs, net of legal settlements with insurance carriers, have been adjusted for the estimated impact of inflation at 3% per year. Changes in enacted laws, regulatory orders or decrees, management’s estimates of costs, risk-free interest rates, insurance proceeds, participation by other parties, the timing of payments, the input of the Company’s attorneys and outside consultants or other factual circumstances could have a material impact on the amounts recorded for environmental and other contingent liabilities. Refer to Note 11, “Commitments and Contingencies”, of these Consolidated Financial Statements for additional discussion and analysis.

Asset Retirement Obligations

Under U.S. GAAP, asset retirement obligations generally apply to legal obligations associated with the retirement of long-lived assets that result from the acquisition, construction, development and/or the normal operation of a long-lived asset. The Company recognizes asset retirement obligations in the period in which they are incurred if a reasonable estimate of fair value can be made. The associated asset retirement costs are capitalized as part of the carrying amount of the long-lived asset.

The Company has recognized as a liability the present value of the estimated future costs to decommission its nuclear laundry facilities. The Company depreciates, on a straight-line basis, the amount added to property, plant and equipment and recognizes accretion expense in connection with the discounted liability over the various remaining lives which range from approximately one to twenty-one years.

The estimated liability has been based on historical experience in decommissioning nuclear laundry facilities, estimated useful lives of the underlying assets, external vendor estimates as to the cost to decommission these assets in the future, and federal and state regulatory requirements. The estimated current costs have been adjusted for the estimated impact of inflation at 3% per year. The liability has been discounted using credit-adjusted risk-free rates that range from approximately 7.0% to 7.5%. Revisions to the liability could occur due to changes in the Company’s estimated useful lives of the underlying assets, estimated dates of decommissioning, changes in decommissioning costs, changes in federal or state regulatory guidance on the decommissioning of such facilities, or other changes in estimates. Changes due to revised estimates are recognized by adjusting the carrying amount of the liability and the related long-lived asset if the assets are still in service, or charged to expense in the period if the assets are no longer in service.

Insurance

The Company is self-insured for certain obligations related to health and dental, workers’ compensation, vehicles and general liability programs. The Company also purchases stop-loss insurance policies for workers’ compensation, vehicles and general liability programs to protect itself from catastrophic losses. Judgments and estimates are used in determining the potential value associated with reported claims and for events that have occurred, but have not been reported. The Company’s estimates consider historical claims experience and other factors. In certain cases where partial insurance coverage exists, the Company estimates the portion of the liability that will be covered by existing insurance policies to arrive at its net expected liability. Receivables for insurance recoveries are recorded as assets, on an undiscounted basis. The Company’s liabilities are based on estimates, and, while the Company believes that its accruals are adequate, the ultimate liability may be significantly different from the amounts recorded. Changes in claims experience, the Company’s ability to settle claims or other estimates and judgments used by management could have a material impact on the amount and timing of expense for any period.

Supplemental Executive Retirement Plan and Other Pension Plans

Pension expense is recognized on an accrual basis over employees’ estimated service periods. Pension expense is generally independent of funding decisions or requirements.

The Company (1) recognizes in its statement of financial position the over-funded or under-funded status of its defined benefit post-retirement plans measured as the difference between the fair value of plan assets and the benefit obligation, (2) recognizes as a component of other comprehensive (loss) income, net of tax, the actuarial gains and losses and the prior service costs and credits that arise during the period but are not recognized as components of net periodic benefit cost, (3) measures defined benefit plan assets and defined benefit plan obligations as of the date of its statement of financial position, and (4) discloses additional information in the notes to financial statements about certain effects on net periodic benefit cost in the upcoming fiscal year that arise from delayed recognition of the actuarial gains and losses and the prior service costs and credits. Refer to Note 7, “Employee Benefit Plans”, of these Consolidated Financial Statements for further discussion regarding the Company’s pension plans.

The calculation of pension expense and the corresponding liability requires the use of a number of critical assumptions, including the expected long-term rates of return on plan assets, the assumed discount rates, assumed rate of compensation increases and life expectancy of participants. Changes in these assumptions can result in different expense and liability amounts, and future actual experience can differ from these assumptions. Pension expense increases as the expected rate of return on pension plan assets decreases. Future changes in plan asset returns, assumed discount rates and various other factors related to the participants in the Company’s pension plans will impact the Company’s future pension expense and liabilities. The Company cannot predict with certainty what these factors will be in the future.

Nonqualified Deferred Compensation Plan

Non-qualified Deferred Compensation Plan

The Company adopted the UniFirst Corporation Deferred Compensation Plan (the “NQDC Plan”) effective on February 1, 2022. The NQDC Plan is an unfunded, non-qualified deferred compensation plan that allows eligible participants to voluntarily defer receipt of their salary and annual cash bonuses up to approved limits. In its discretion, the Company may credit one or more additional contributions to participant accounts. NQDC Plan participants who are not accruing benefits under the Supplemental Executive Retirement Plan are eligible to have discretionary annual employer contributions credited

to their NQDC Plan accounts. All participants are also eligible to have employer supplemental contributions and employer discretionary contributions credited to their NQDC Plan accounts. The amounts of such contributions may differ from year to year and from participant to participant. Refer to Note 7, “Employee Benefit Plans”, of these Consolidated Financial Statements for further discussion regarding the Company’s NQDC Plan

Income Taxes

The Company computes income tax expense by jurisdiction based on its operations in each jurisdiction. Deferred income taxes are provided for temporary differences between the amounts recognized for income tax and financial reporting purposes at currently enacted tax rates. Deferred tax assets and liabilities are determined by the differences between the consolidated financial statement carrying amounts and the tax basis of assets and liabilities. See Note 4, “Income Taxes” in these Consolidated Financial Statements for the types of items that give rise to significant deferred income tax assets and liabilities. Deferred income taxes are classified as assets or liabilities based on the classification of the related asset or liability for financial reporting purposes. The Company regularly reviews deferred tax assets for recoverability based upon projected future taxable income and the expected timing of the reversals of existing temporary differences. Although realization is not assured, management believes it is more likely than not that the recorded deferred tax assets will be realized.

The Company is periodically reviewed by U.S. domestic and foreign tax authorities regarding the amount of taxes due. These reviews typically include inquiries regarding the timing and amount of deductions and the allocation of income among various tax jurisdictions. In evaluating the exposure associated with various filing positions, the Company records estimated reserves. Refer to Note 4, “Income Taxes”, of these Consolidated Financial Statements for further discussion regarding the Company’s accounting for income taxes and its uncertain tax positions for financial accounting purposes.

Advertising Costs

Advertising costs are expensed as incurred and are classified as selling and administrative expenses. The Company incurred advertising costs of $5.3 million, $9.9 million and $14.7 million, for fiscal 2024, 2023 and 2022, respectively.

Share-Based Compensation

Compensation expense for all stock options, stock appreciation rights, unrestricted stock and restricted stock units (collectively, “Share-Based Awards”) is recognized ratably over the related vesting period, net of actual forfeitures. Certain Share-Based Awards in the form of stock appreciation rights and shares of unrestricted stock were granted during fiscal 2024, 2023 and 2022 to non-employee Directors of the Company, which were fully vested upon grant and, with respect to stock appreciation rights, expire eight years after the grant date. Accordingly, compensation expense related to these Share-Based Awards in fiscal 2024, 2023 and 2022 was recognized on the date of grant.

For performance-based restricted stock unit awards with revenue and profitability performance criteria, we evaluate the probability of meeting the performance criteria at each balance sheet date and, if probable, related compensation cost is amortized over the performance period on a straight-line basis because such awards vest only at the end of the measurement period. Changes to the probability assessment and the estimate of shares expected to vest will result in adjustments to the related share-based compensation expense that will be recorded in the period of the change. If the performance targets are not achieved, no compensation cost is recognized and any previously recognized compensation cost is reversed.

U.S. GAAP requires that share-based compensation cost be measured at the grant date based on the fair value of the award and be recognized as expense over the requisite service period, which is generally the vesting period. Determining the fair value of Share-Based Awards in the form of stock appreciation rights at the grant date requires judgment, including estimating expected dividends and share price volatility. The fair value of each Share-Based Award in the form of stock appreciation rights is estimated on the date of grant using the Black-Scholes option pricing model.

The Company recognizes compensation expense for restricted stock and restricted stock unit grants over the related vesting period. The fair value for each restricted stock, unrestricted stock and restricted stock unit grant is determined by using the closing price of the Company’s stock on the date of the grant. Refer to Note 12, “Share-Based Compensation”, of these Consolidated Financial Statements for further discussion regarding the Company’s share-based compensation plans.

Income Per Share

The Company calculates income per share by allocating income to its unvested participating securities as part of its income per share calculations. The following table sets forth the computation of basic income per share using the two-class method for amounts attributable to the Company’s shares of Common Stock and Class B Common Stock (in thousands, except per share data):


Year ended	2024		2023		2022
Net income available to shareholders	$	145,474	$	103,674	$	103,404
Allocation of net income for Basic:
Common Stock	$	122,188	$	87,104	$	86,844
Class B Common Stock		23,286		16,570		16,560
	$	145,474	$	103,674	$	103,404
Weighted average number of shares for Basic:
Common Stock		15,073		15,098		15,203
Class B Common Stock		3,590		3,590		3,621
		18,663		18,688		18,824
Income per share for Basic:
Common Stock	$	8.11	$	5.77	$	5.71
Class B Common Stock	$	6.49	$	4.62	$	4.57

The Class B Common Stock may be converted at any time on a one-for-one basis into Common Stock at the option of the holder of the Class B Common Stock. Diluted income per share for the Company’s Common Stock assumes the conversion of all of the Company’s Class B Common Stock into Common Stock, full vesting of outstanding restricted stock, and the exercise of Share-Based Awards under the Company’s stock incentive plans.

The Company is required to calculate the diluted income per share for Common Stock using the more dilutive of the following two methods:

•

The treasury stock method; or

•

The two-class method assuming a participating security is not exercised or converted.

For fiscal 2024, 2023 and 2022, the Company’s diluted income per share assumes the conversion of all Class B Common Stock into Common Stock and uses the two-class method for its unvested participating shares.

The following table sets forth the computation of diluted income per share of Common Stock for the years ended August 31, 2024, August 26, 2023 and August 27, 2022 (in thousands, except per share data):


	Year Ended August 31, 2024						Year Ended August 26, 2023						Year Ended August 27, 2022
	Earnings to Common shareholders		Common Shares		Income Per Share		Earnings to Common shareholders		Common Shares		Income Per Share		Earnings to Common shareholders		Common Shares		Income Per Share
As reported—Basic	$	122,188		15,073	$	8.11	$	87,104		15,098	$	5.77	$	86,844		15,203	$	5.71
Add: effect of dilutive potential common shares
Share-Based Awards		—		61				—		74				—		109
Class B Common Stock		23,286		3,590				16,570		3,590				16,560		3,621
Diluted Income Per Share— Common Stock	$	145,474		18,724	$	7.77	$	103,674		18,762	$	5.53	$	103,404		18,933	$	5.46

Share-Based Awards that would result in the issuance of 60,260, 51,708 and 34,416 shares, respectively, of Common Stock were excluded from the calculation of diluted earnings per share for fiscal 2024, 2023 and 2022 because they were anti-dilutive.

Foreign Currency Translation

The functional currency of our foreign operations is the local country’s currency. Transaction gains and losses, including gains and losses on our intercompany transactions, are included in other expense, net in the accompanying Consolidated Statements of Income. Assets and liabilities of operations outside the U.S. are translated into U.S. dollars using period-end exchange rates. Revenues and expenses are translated at the average exchange rates in effect during each month of the fiscal year. The effects of foreign currency translation adjustments are included in shareholders’ equity as a component of accumulated other comprehensive loss in the accompanying Consolidated Balance Sheets.

Recent Accounting Pronouncements

In November 2023, the Financial Accounting Standards Board (“FASB”) issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which updates reportable segment disclosure requirements primarily through enhanced disclosures about significant segment expenses. The amendments are effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The amendments should be applied retrospectively to all prior periods presented in the financial statements. The Company is currently evaluating this ASU to determine its impact on the Company’s disclosures.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which enhances effective tax rate reconciliation disclosure requirements and provides clarity to the disclosures of income taxes paid, income before taxes and provision for income taxes. The amendments are effective for fiscal years beginning after December 15, 2024. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. The amendments in this update should be applied on a prospective basis. Retrospective application is permitted. The Company is currently evaluating this ASU to determine its impact on the Company’s disclosures.

Other recent accounting pronouncements issued by the FASB, including its Emerging Issues Task Force, the American Institute of Certified Public Accountants, and the SEC have not had, or are not believed by management to, have a material impact on the Company’s present or future financial statements.

Business Combinations [Abstract]

Acquisitions

2. Acquisitions

Whenever the Company acquires a business, consistent with current accounting guidance, the results of operations of the acquisition are included in the Company’s consolidated financial results from the date of the acquisition. The amount assigned to intangible assets acquired is based on their respective fair values determined as of the acquisition date. The excess of the purchase price over the tangible and intangible assets is recorded as goodwill. Goodwill is allocated to the segment to which the acquisition relates and is deductible for tax purposes. During fiscal 2024, the Company did not complete any material business acquisitions.

Clean Uniform

During the third quarter of fiscal 2023, the Company completed the acquisition of the business and certain real estate assets of Clean Uniform (“Clean”) from Clean Holdco, Inc. and certain of its affiliates for an aggregate purchase price of $299.1 million, net of cash acquired. The difference between the cash paid and the total purchase price of $302.4 million represented amounts owed from the seller as a result of final closing adjustments. The acquisition was structured primarily as a stock purchase but was treated as an asset purchase from a tax perspective, which has allowed for a step-up in the tax basis of the assets and provides incremental tax benefits expected to be realized over time with a value of approximately $40 million. Clean was a uniform, workwear and facility service program provider with 11 locations covering Missouri, Illinois, Arkansas, Kansas and Oklahoma. Prior to the closing of the acquisition, neither the Company nor any of its affiliates, or any director or officer of the Company or any of its affiliates, or any associate of any such director or officer, had any material relationship with any of the sellers. The results of operations from Clean are included in the Company’s results under the U.S. and Canadian Rental and Cleaning segment subsequent to the acquisition date of March 13, 2023. The Company paid for the acquisition of Clean with cash on hand and borrowings under the Credit Agreement (defined below).

The Clean acquisition was accounted for using the purchase method of accounting. The Company has measured the fair value of its tangible and intangible assets acquired and liabilities assumed in the Clean acquisition and has finalized the purchase price allocations. The amounts assigned to intangible assets acquired were based on their respective fair values determined as of the acquisition date, which the Company determined by engaging specialists to assist in their valuation. The table below summarizes the final purchase price allocation to the estimated fair value of assets acquired and liabilities assumed at the acquisition date. Goodwill is calculated as the excess of the purchase price over the net assets recognized and represents the estimated future economic benefits arising from expected synergies and growth opportunities for the Company. All of the goodwill and intangible assets were allocated to the U.S. and Canadian Rental and Cleaning segment and are deductible for tax purposes.

Transaction and related costs, consisting primarily of professional fees, directly related to the acquisition, totaled approximately $3.0 million during fiscal 2023. All transaction and related costs were expensed as incurred and are included in selling and administrative expenses.

The final purchase price allocation is as follows (in thousands):


Receivables	$	8,301
Inventories		632
Rental merchandise in service		8,535
Prepaid expenses and other current assets		762
Property, plant and equipment		31,497
Operating lease right-of-use assets, net		3,517
Goodwill and intangible assets		257,833
Accounts payable		(2,011	)
Accrued liabilities		(5,767	)
Operating lease liabilities, current		(1,510	)
Operating lease liabilities, non-current		(2,657	)
Total purchase price	$	299,132

The following table identifies the Company’s allocation of purchase price to the intangible assets and goodwill acquired by category:


Year ended	Estimated Fair Value (in thousands)		Weighted Average Life (in years)
Goodwill	$	187,733	N/A
Customer contracts		64,800		15.0
Trade name		5,300		3.0
Total intangible assets and goodwill acquired	$	257,833

The amount of amortization expense recognized of Clean customer contracts and trade name included in the consolidated statements of income from the acquisition date of March 13, 2023 to August 26, 2023 was $3.8 million and $0.9 million, respectively.

Unaudited pro-forma information presents the combined financial results for the Company and Clean as if the acquisition of Clean had occurred on August 28, 2022. The unaudited pro-forma revenue of the combined entity for fiscal 2023 was $2.3 billion reflecting the effects of the Clean acquisition. The effects of the Clean acquisition on unaudited pro-forma net income of the combined entity were not material for fiscal 2023.

Other Acquisitions

During fiscal 2023, the Company completed four other business acquisitions with an aggregate purchase price of approximately $7.1 million. Tangible assets acquired primarily relate to accounts receivable, inventory and property, plant and equipment. The results of operations of all acquisitions completed during fiscal 2023 have been included in the Company’s consolidated financial results since their respective acquisition dates. These acquisitions were not significant in relation to the Company’s consolidated financial results and, therefore, pro-forma financial information has not been presented.

The following table identifies the Company’s allocation of purchase price to the intangible assets and goodwill acquired by category:

Share-Based Payment Arrangement [Abstract]

Share-based Compensation

12. Share-based Compensation

The Company adopted an equity incentive plan (the “2023 Plan”) in October 2023 and reserved 375,000 shares of Common Stock for issuance under the 2023 Plan. The 2023 Plan, which was approved by the Company's shareholders in January 2024, replaced the Company’s 2010 stock incentive plan (the “2010 Plan”). Upon approval of the 2023 Plan by the Company’s shareholders, no further awards may be granted under the 2010 Plan. The 2023 Plan permits the award of incentive and non-qualified stock options, stock appreciation rights, restricted stock, restricted stock units and unrestricted stock (collectively referred to as “Share-Based Awards”) as well as dividend equivalent rights and cash-based awards. As of August 31, 2024, the number of remaining shares available for future grants under the 2023 Plan was 375,000. Share-based compensation expense, which includes expense related to Share-Based Awards, has been recorded in the accompanying Consolidated Statements of Income in selling and administrative expenses.

All Share-Based Awards issued to management were recommended to the Board of Directors by the Compensation Committee and approved by the Board of Directors. All Share-Based Awards issued to the Company’s non-employee members of the Board of Directors (the “Directors”) were recommended to the Board of Directors by the Compensation Committee and approved by the Board of Directors.

In fiscal 2024, a total of 1,475 shares of fully vested unrestricted stock were granted to non-employee Directors of the Company. In fiscal 2023, a total of 1,575 shares of fully vested unrestricted stock were granted to non-employee Directors of the Company. In fiscal 2022, a total of 1,025 shares of fully vested unrestricted stock were granted to certain non-employee Directors of the Company. Accordingly, compensation expense related to the unrestricted stock granted in each of fiscal 2024, 2023 and 2022 were recognized on the date of grant.

In fiscal 2024, the Company granted a total of 5,004 stock appreciation rights to the Company’s non-employee Directors. In fiscal 2023, the Company granted a total of 6,864 stock appreciation rights to the Company’s non-employee Directors. In fiscal 2022, the Company granted a total of 9,750 stock appreciation rights to the Company’s non-employee Directors. Such stock appreciation rights were fully vested upon grant, expire on the earlier of the eighth anniversary of the grant date or the second anniversary of the date that the Director ceases to be a member of the Board of Directors and must be settled in stock at the time of exercise. Accordingly, compensation expense related to the stock appreciation rights was recognized on the date of grant.

As of August 31, 2024, the total compensation cost not yet recognized related to non-vested Share-Based Awards was approximately $16.0 million. The weighted average period over which compensation cost for Share-Based Awards will be recognized is 3.02 years.

All stock appreciation rights issued to employees were granted with an exercise price equal to the fair value of the Company’s Common Stock on the date of grant. Stock appreciation rights generally vest 20% on each anniversary of the grant date over a five-year period and expire ten years after the grant date. Share-Based Awards granted to the Company’s non-employee Directors were fully vested as of the date of grant. Non-employee Director Share-Based Award grants in the form of stock appreciation rights expire on the earlier of the eighth anniversary of the grant date or the second anniversary of the date that the Director ceases to be a member of the Board of Directors.

Time-based restricted stock units granted to employees generally vest 20% on each anniversary of the grant date over a five-year period. Generally, performance-based restricted stock units granted to employees are earned based on whether and the extent to which the Company achieves certain revenue and operating margin targets.

The fair value of each stock appreciation right is estimated on the date of grant using the Black-Scholes option pricing model with the following weighted average assumptions used:


Year ended	2024			2023			2022
Risk-free interest rate		4.85	%		3.97	%		1.27	%
Expected dividend yield		0.80	%		0.62	%		0.60	%
Expected life (in years)		5.54			5.43			5.17
Expected volatility		29.4	%		29.3	%		28.4	%

The weighted average fair value of Share-Based Awards granted in the form of stock appreciation rights during fiscal years 2024, 2023 and 2022 were $55.97, $60.38 and $51.25, respectively.

Asset Retirement Obligation Disclosure [Abstract]

Asset Retirement Obligations

10. Asset Retirement Obligations

Asset retirement obligations generally result from legal obligations associated with the retirement of long-lived assets that result from the acquisition, construction, development and/or the normal operation of a long-lived asset. Accordingly, the Company recognizes asset retirement obligations in the period in which they are incurred if a reasonable estimate of fair value can be made. The associated asset retirement costs are capitalized as part of the carrying amount of the long-lived asset. The Company continues to depreciate, on a straight-line basis, the amount added to property, plant and equipment and recognizes accretion expense in connection with the discounted liability over the various remaining lives which range from approximately one to twenty-one years.

The Company recognized as a liability the present value of the estimated future costs to decommission its nuclear laundry facilities. The estimated liability is based on historical experience in decommissioning nuclear laundry facilities, estimated useful lives of the underlying assets, external vendor estimates as to the cost to decommission these assets in the future, and federal and state regulatory requirements. The estimated current costs have been adjusted for the estimated impact of inflation at 3% per year, and the liability has been discounted to present value using a credit-adjusted risk-free rate.

Revisions to the liability could occur due to changes in the Company’s estimated useful lives of the underlying assets, estimated dates of decommissioning, changes in decommissioning costs, changes in federal or state regulatory guidance on the decommissioning of such facilities, or other changes in estimates. Changes due to revised estimates are recognized by adjusting the carrying amount of the liability and the related long-lived asset if the assets are still in service, or charged to expense in the period if the assets are no longer in service.

A reconciliation of the Company’s asset retirement are as follows for fiscal 2024 and 2023 (in thousands):

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments and Hedging Activities

6. Derivative Instruments and Hedging Activities

The Company uses derivative financial instruments to mitigate its exposure to fluctuations in foreign currencies on certain forecasted transactions denominated in foreign currencies. U.S. GAAP requires that all of the Company’s derivative instruments be recorded on the balance sheet at fair value. All subsequent changes in a derivative’s fair value are recognized in income, unless specific hedge accounting criteria are met.

Derivative instruments that qualify for hedge accounting are classified as a hedge of the variability of cash flows to be received or paid related to a recognized asset, liability or forecasted transaction. Changes in the fair value of a derivative that is highly effective and designated as a cash flow hedge are recognized in accumulated other comprehensive (loss) income until the hedged item or forecasted transaction is recognized in earnings. The Company performs an assessment at the inception of the hedge and on a quarterly basis thereafter, to determine whether its derivatives are highly effective in offsetting changes in the value of the hedged items. Any changes in the fair value resulting from hedge ineffectiveness are immediately recognized as income or expense.

In August 2021, the Company entered into twenty forward contracts to exchange CAD for U.S. dollars at fixed exchange rates in order to manage its exposure related to certain forecasted CAD denominated sales of one of its subsidiaries. The hedged transactions are specified as the first amount of CAD denominated revenues invoiced by one of the Company’s domestic subsidiaries each fiscal quarter, beginning in the first fiscal quarter of 2022 and continuing through the fourth fiscal quarter of 2026. In total, the Company will sell approximately 14.1 million CAD at an average Canadian-dollar exchange rate of 0.7861 over these quarterly periods. The Company concluded that the forward contracts met the criteria to qualify as a cash flow hedge under U.S. GAAP.

As of August 31, 2024, the Company had forward contracts with a notional value of approximately 3.6 million CAD outstanding and recorded the fair value of the contracts of $0.1 million in prepaid expenses and other current assets with a corresponding gain of $0.1 million in accumulated other comprehensive loss, which was recorded net of tax. For the fiscal 2024, the Company reclassified $0.1 million from accumulated other comprehensive loss to revenue, related to the derivative financial instruments. The gain on these forward contracts that results in a decrease to accumulated other comprehensive loss as of August 31, 2024 is expected to be reclassified to revenues prior to their maturity on August 29, 2026.

Equity [Abstract]

Shareholders' Equity

13. Shareholders’ Equity

The Company has two classes of common stock: Common Stock and Class B Common Stock. Each share of Common Stock is entitled to one vote, is freely transferable, and is entitled to a cash dividend equal to 125% of any cash dividend paid on each share of Class B Common Stock. Each share of Class B Common Stock is entitled to ten votes and can be converted to Common Stock on a share-for-share basis. However, until converted to Common Stock, shares of Class B Common Stock are not freely transferable. During fiscal 2022, 17,000 shares of Class B Common Stock were converted to Common Stock. No such conversions occurred during each of fiscal 2024 and 2023.

On October 24, 2023, the Company’s Board of Directors authorized a new share repurchase program to repurchase from time to time up to $100.0 million of its outstanding shares of Common Stock, inclusive of the amount which remained available under the existing share repurchase program approved on October 18, 2021. Repurchases from time to time under the new program, if any, will be made in either the open market or in privately negotiated transactions. The timing, manner, price and amount of any repurchases will depend on a variety of factors, including economic and market conditions, the Company stock price, corporate liquidity requirements and priorities, applicable legal requirements and other factors. The share

repurchase program has been funded to date with the Company’s available cash and will be funded in the future using the Company’s available cash or capacity under its Credit Agreement and may be suspended or discontinued at any time.

On October 29, 2024, the Company’s Board of Directors declared increased quarterly cash dividends of $0.350 per share of Common Stock and $0.280 per share of Class B Common Stock, up from $0.33 and $0.264 per share, respectively. Both dividends are payable on January 3, 2025 to shareholders of record as of December 6, 2024. The amount and timing of any future dividend payment is subject to the approval of the Board of Directors each quarter.

During fiscal 2024, the Company repurchased 139,556 shares for an average price per share of $170.40. During fiscal 2023, the Company did not repurchase any shares. During fiscal 2022, the Company repurchased 213,419 shares for an average price per share of $179.98. As of August 31, 2024, there was $76.2 million remaining to repurchase outstanding shares of Common Stock under the existing program.

Fair Value Disclosures [Abstract]

Fair Value Measurements

3. Fair Value Measurements

U.S. GAAP establishes a framework for measuring fair value and establishes disclosure requirements about fair value measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company considered non-performance risk when determining fair value of our derivative financial instruments.

The fair value hierarchy prescribed under U.S. GAAP contains three levels as follows:

Level 1 - Quoted prices in active markets for identical assets or liabilities.

Level 2 - Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.

All financial assets or liabilities that are measured at fair value on a recurring basis (at least annually) have been segregated into the most appropriate level within the fair value hierarchy based on the inputs used to determine the fair value at the measurement date. The assets or liabilities measured at fair value on a recurring basis are summarized in the tables below (in thousands):


	As of August 31, 2024								As of August 26, 2023
	Level 1		Level 2		Level 3		Total		Level 1		Level 2		Level 3		Total

The Company's short-term investments listed above represent certificates of deposit, which maturities range up to six months at purchase. Such securities are classified as held-to-maturity and are carried at amortized cost, which approximates market value. As such, the Company's short-term investments are included within Level 2 of the fair value hierarchy.

The Company’s pension plan assets listed above represent guaranteed deposit accounts that are maintained and operated by a third-party investment manager. At the beginning of each calendar year, the third-party investment manager notifies the Company of the annual rates of interest which will be applied to the amounts held in the guaranteed deposit account during the next calendar year. In determining the interest rate to be applied, the third-party investment manager considers the investment performance of the underlying assets of the prior year; however, regardless of the investment performance the annual interest rate applied per the contract must be a minimum of 3.25%. As such, the Company’s pension plan assets are included within Level 2 of the fair value hierarchy. Refer to Note 7, “Employee Benefit Plans”, of these Consolidated Financial Statements for further discussion regarding the Company’s pension plan and Supplemental Executive Retirement Plan.

The Company's non-qualified deferred compensation plan liability listed above is carried at fair value and is composed primarily of mutual funds, municipal bonds and other fixed income securities. As such, the Company’s non-qualified deferred compensation plan assets and liabilities are included within Level 2 of the fair value hierarchy. Refer to Note 7, “Employee Benefit Plans”, of these Consolidated Financial Statements for further discussion regarding the Company’s non-qualified deferred compensation plan.

The Company’s foreign currency forward contracts represent contracts the Company has entered into to exchange Canadian dollars for U.S. dollars at fixed exchange rates in order to manage its exposure related to certain forecasted Canadian dollar denominated sales of one of its subsidiaries. These contracts are included in prepaid expenses and other current assets and other long-term assets as of August 31, 2024 and August 26, 2023. The fair value of the forward contracts is based on similar exchange-traded derivatives and is, therefore, included within Level 2 of the fair value hierarchy.

Segment Reporting [Abstract]

Segment Reporting

15. Segment Reporting

Operating segments are identified as components of an enterprise for which separate discrete financial information is available for evaluation by the chief operating decision-maker, or decision-making group, in making decisions on how to allocate resources and assess performance. The Company’s chief operating decision-maker is the Company’s Chief Executive Officer. The Company has six operating segments based on the information reviewed by its Chief Executive Officer: U.S. Rental and Cleaning, Canadian Rental and Cleaning, MFG, Specialty Garments, First Aid and Corporate. The U.S. Rental and Cleaning and Canadian Rental and Cleaning operating segments have been combined to form the U.S. and Canadian Rental and Cleaning reporting segment, and as a result, the Company has five reporting segments.

The U.S. and Canadian Rental and Cleaning reporting segment purchases, rents, cleans, delivers and sells, uniforms and protective clothing and non-garment items in the U.S. and Canada. The laundry locations of the U.S. and Canadian Rental and Cleaning reporting segment are referred to by the Company as “industrial laundries” or “industrial laundry locations.”

The MFG operating segment designs and manufactures uniforms and non-garment items primarily for the purpose of providing these goods to the U.S. and Canadian Rental and Cleaning reporting segment. MFG revenues are primarily generated when goods are shipped from the Company’s manufacturing facilities, or its subcontract manufacturers, to other Company locations. These intercompany revenues are recorded at a transfer price which is typically in excess of the actual manufacturing cost. Manufactured products are carried in inventory until placed in service at which time they are amortized at this transfer price. On a consolidated basis, intercompany revenues and income are eliminated and the carrying value of inventories and rental merchandise in service is reduced to the manufacturing cost. Income before income taxes from MFG net of the intercompany MFG elimination offsets the merchandise amortization costs incurred by the U.S. and Canadian Rental and Cleaning reporting segment as the merchandise costs of this reporting segment are amortized and recognized based on inventories purchased from MFG at the transfer price which is above the Company’s manufacturing cost.

The Corporate operating segment consists of costs associated with the Company’s distribution center, sales and marketing, information systems, engineering, procurement, supply chain, accounting and finance, human resources, other general and administrative costs and interest expense. The revenues generated from the Corporate operating segment represent certain direct sales made by the Company directly from its distribution center. The products sold by this operating segment are the same products rented and sold by the U.S. and Canadian Rental and Cleaning reporting segment. In the table below, no assets or capital expenditures are presented for the Corporate operating segment because no assets are allocated to this operating segment in the information reviewed by the chief executive officer. However, depreciation and amortization expense related to certain assets are reflected in income from operations and income before income taxes for the Corporate operating segment. The assets that give rise to this depreciation and amortization are included in the total assets of the U.S. and Canadian Rental and Cleaning reporting segment as this is how they are tracked and reviewed by the Company. The majority of expenses accounted for within the Corporate segment relate to costs of the U.S. and Canadian Rental and Cleaning segment, with the remainder of the costs relating to the Specialty Garment and First Aid segments.

The Specialty Garments operating segment purchases, rents, cleans, delivers and sells, specialty garments and non-garment items primarily for nuclear and cleanroom applications and provides cleanroom cleaning services at certain customer locations. The First Aid operating segment sells first aid cabinet services and other safety supplies, provides certain safety training and maintains wholesale distribution and pill packaging operations for non-prescription medicines.

Employee Benefit Plans

7. Employee Benefit Plans

Defined Contribution Retirement Savings Plan

The Company has a defined contribution retirement savings plan with a 401(k) feature for all eligible U.S. and Canadian employees not under collective bargaining agreements. The Company matches a portion of the employee’s contribution and may make an additional contribution at its discretion. Contributions charged to expense under the plan for fiscal 2024, 2023 and 2022 were $20.3 million, $18.7 million and $18.2 million, respectively.

Pension Plan and Supplemental Executive Retirement Plan

The Company accounts for its pension plan and Supplemental Executive Retirement Plan on an accrual basis over employees’ estimated service periods.

The Company maintains an unfunded Supplemental Executive Retirement Plan (“SERP”) for certain eligible employees of the Company. The benefits are based on the employee’s compensation upon retirement. The amount charged to expense related to this plan amounted to approximately $1.7 million, $1.7 million and $1.5 million for fiscal 2024, 2023 and 2022, respectively.

The Company maintains a non-contributory defined benefit pension plan (“UniFirst Plan”) covering employees at one of its locations. The benefits are based on years of service. The UniFirst Plan assets are invested in a Guaranteed Deposit Account (“GDA”) that is maintained and operated by a third-party investment manager. The amount charged to expense related to this plan amounted to approximately $0.2 million, $0.1 million and $0.1 million for fiscal 2024, 2023 and 2022, respectively.

Net periodic benefit cost other than service costs have been recorded in the accompanying Consolidated Statements of Income in other expense, net.

Non-qualified Deferred Compensation Plan

The Company adopted the NQDC Plan effective on February 1, 2022. The NQDC Plan is an unfunded, non-qualified deferred compensation plan that allows eligible participants to voluntarily defer receipt of their salary and annual cash bonuses up to approved limits. In its discretion, the Company may credit one or more additional contributions to participant accounts. NQDC Plan participants who are not accruing benefits under the Supplemental Executive Retirement Plan are eligible to have discretionary annual employer contributions credited to their NQDC Plan accounts. All participants are also eligible to have employer supplemental contributions and employer discretionary contributions credited to their NQDC Plan accounts. The amounts of such contributions, if any, may differ from year to year and from participant to participant.

The amounts for employee or employer contributions charged to expense related to the NQDC Plan for fiscal 2024, fiscal 2023 and fiscal 2022, were $0.8 million, $0.3 million and nominal, respectively.

The Company, at its discretion, may also elect to transfer funds to a trust account with the intention to fund the future liability. Total NQDC Plan assets were $3.3 million and $2.0 million as of August 31, 2024 and August 26, 2023, respectively, and are included within other long-term assets in the accompanying Consolidated Balance Sheets. Total NQDC Plan liabilities were $1.6 million and $0.5 million as of August 31, 2024 and August 26, 2023, respectively, and are included within current accrued liabilities in the accompanying Consolidated Balance Sheets.

Earnings and losses on contributions, based on these investment elections, are recorded as a component of compensation expense in the period earned and are included within other (income) expense, net.
