ABM Industries Incorporated:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of ABM Industries Incorporated and subsidiaries (the Company) as of October 31, 2024 and 2023, the related consolidated statements of comprehensive income, stockholders’ equity, and cash flows for each of the years in the three-year period ended October 31, 2024, and the related notes and financial statement schedule II (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of October 31, 2024 and 2023, and the results of its operations and its cash flows for each of the years in the three-year period ended October 31, 2024, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of October 31, 2024, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated December 19, 2024, expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Valuation of self-insurance liabilities

As discussed in Notes 2 and 10 to the consolidated financial statements, the Company uses a combination of insured and self-insurance programs to cover insurable risks. The balance of casualty program insurance reserves as of October 31, 2024, amounted to $608.4 million, a portion of which related to workers’ compensation and general liability self-insurance liabilities. The Company engages actuaries to estimate its self-insurance liabilities at least annually.

We identified the evaluation of certain workers’ compensation and general liability self-insurance liabilities as a critical audit matter because it involves a high degree of judgment and actuarial expertise to assess: (1) the application of actuarial models used and (2) estimated incurred but not reported claims based on application of loss development factors to historical claims experience.

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls over the Company’s self-insurance liability process, including controls related to (1) evaluation of claims information sent to the actuary, (2) estimation of incurred but not reported claims based on the application of loss development factors to historical claims experience, and (3) evaluation of the actuarial report and the external actuarial specialist’s qualifications and competency. We evaluated the Company’s historical ability to estimate self-insurance liabilities by comparing the prior year recorded amounts to the subsequent claim development. We tested a sample of the claims data utilized by the Company’s actuaries by comparing it to underlying claims details; and involved an actuarial professional with specialized skills and knowledge who assisted in the:

•assessment of the application of the actuarial models used by the Company for consistency with generally accepted actuarial standards and

•development of an actuarial estimate of self-insurance liabilities based on the Company’s underlying historical paid and incurred loss data for comparison with the liabilities recorded by the Company.

Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors

ABM Industries Incorporated:

Opinion on Internal Control Over Financial Reporting

We have audited ABM Industries Incorporated and subsidiaries’ (the Company) internal control over financial reporting as of October 31, 2024, based on criteria established in Internal Control – Integrated Framework (2013)issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of October 31, 2024, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of October 31, 2024 and 2023, the related consolidated statements of comprehensive income, stockholders’ equity, and cash flows for each of the years in the three-year period ended October 31, 2024, and the related notes and financial statement schedule II (collectively, the consolidated financial statements), and our report dated December 19, 2024, expressed an unqualified opinion on those consolidated financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

CONSOLIDATED BALANCE SHEETS

CONSOLIDATED STATEMENTS OF COMPREHENSIVE INCOME

CONSOLIDATED STATEMENTS OF STOCKHOLDERS’ EQUITY

CONSOLIDATED STATEMENTS OF CASH FLOWS

CONSOLIDATED STATEMENTS OF CASH FLOWS

(continued)

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. THE COMPANY AND NATURE OF OPERATIONS

ABM is a leading provider of integrated facility services with a mission tomake a difference, every person, every day. We are organized into four industry groups andone Technical Solutions segment:

Through these groups, we offer janitorial, facilities engineering, parking, and specialized mechanical and electrical technical solutions, on a standalone basis or in combination with other services.

2. BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation and Principles of Consolidation

The Financial Statements have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) and with the rules and regulations of the SEC, specifically Regulation S-X and the instructions to Form 10-K. Unless otherwise indicated, all references to years are to our fiscal year, which ends on October 31.

The Financial Statements include the accounts of ABM and all of our consolidated subsidiaries. We account for ABM’s investments in unconsolidated affiliates under the equity method of accounting. We include the results of acquired businesses in the Consolidated Statements of Comprehensive Income from their respective acquisition dates. All intercompany accounts and transactions have been eliminated in consolidation.

The preparation of consolidated financial statements in accordance with U.S. GAAP requires our management to make certain estimates that affect reported amounts. We base our estimates on historical experience, known or expected trends, independent valuations, and various other assumptions that we believe to be reasonable under the circumstances. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates.

We round amounts in the Financial Statements to millions and calculate all percentages and per-share data from the underlying whole-dollar amounts. Thus, certain amounts may not foot, crossfoot, or recalculate based on reported numbers due to rounding.

Cash and Cash Equivalents

We consider all highly liquid securities with an original maturity of three months or less to be cash and cash equivalents. As part of our cash management system, we use “zero balance” accounts to fund our disbursements. Under this system, at the end of each day the bank balance is zero, while the book balance is usually a negative amount due to reconciling items, such as outstanding checks. We report the changes in these book cash overdrafts as cash flows from financing activities.

Trade Accounts Receivable and Costs Incurred in Excess of Amounts Billed

Trade accounts receivable arise from services provided to our clients and are usually due and payable on varying terms from receipt of the invoice to net 60 days, with the exception of certain Technical Solutions project receivables that may have longer collection periods. These receivables are recorded at the invoiced amount and normally do not bear interest. In addition, our trade accounts receivable include unbilled receivables, such as invoices for services that have been provided but are not yet billed.

Costs incurred in excess of amounts billed arise from Technical Solutions project contracts that typically provide for a schedule of billings or invoices to the client based on our performance to date of specific tasks inherent in the fulfillment of our performance obligation(s). The schedules for such billings usually do not precisely match the schedule on which costs are incurred. As a result, revenues generally differ from amounts that can be billed or invoiced to the client at any point during the contract.

Allowance for Doubtful Accounts

We determine the allowance for doubtful accounts based on historical write-offs, known or expected trends, and the identification of specific balances deemed uncollectible. For the specifically identified balances, we establish the reserve upon the earlier of a client’s inability to meet its financial obligations or after a period of 12 months, unless our management believes such amounts will ultimately be collectible.

Sales Allowance

In connection with our service contracts, we periodically issue credit memos to our clients that are recorded as a reduction in revenues and an increase to the allowance for billing adjustments. These credits can result from client vacancy discounts, job cancellations, property damage, and other items. We estimate our potential future losses on these client receivables based on an analysis of the historical rate of sales adjustments (credit memos, net of re-bills) and known or expected trends.

Other Current Assets

At October 31, 2024 and 2023, other current assets primarily consisted of other receivables, short-term insurance recoverables, and capitalized commissions.

Other Investments

At October 31, 2024 and 2023, other investments primarily consisted of preferred equity investments and investments in unconsolidated affiliates and were $30.8 million and $28.8 million, respectively. We did not recognize any impairment charges on these investments in 2024, 2023, or 2022.

Property, Plant and Equipment

We record property, plant and equipment at cost. Repairs and maintenance expenditures are expensed as incurred. In contrast, we capitalize major renewals or replacements that substantially extend the useful life of an asset. We determine depreciation for financial reporting purposes using the straight-line method over the following estimated useful lives:

In addition, we depreciate assets under finance leases and leasehold improvements over the shorter of their estimated useful lives or the remaining lease term. Upon retirement or sale of an asset, we remove the cost and accumulated depreciation from our Consolidated Balance Sheets. When applicable, we record corresponding gains or losses within the accompanying Consolidated Statements of Comprehensive Income.

Leases

We account for our leases in accordance with ASU 2016-02, Leases (Topic 842). Topic 842 requires lessees to recognize substantially all leases on their balance sheet as a right-of-use (“ROU”) asset and a lease liability. We made the accounting policy election to not recognize leases with an initial term of 12 months or less on the balance sheet and will expense payments for such leases on a straight-line basis over the lease term. We also elected to not separate lease components from non-lease components.

We enter into various noncancelable lease agreements for office space, parking facilities, warehouses, vehicles, and equipment used in the normal course of business. We determine if an arrangement is a lease at inception and begin recording lease activity at the commencement date. ROU assets and lease liabilities are recognized based on the present value of lease payments over the lease term with lease expense recognized on a straight-line basis. The present value of future lease payments is determined using our incremental borrowing rate (“IBR”) unless the implicit rate in the lease is readily determinable. Our IBR is equal to our rate of interest adjusted for term differences. This IBR is applied to the minimum lease payments within each lease agreement to determine the amounts of our ROU assets and lease liabilities.

Our lease terms range fromone to 20 years. Some leases include options to renew or extend. We typically include extension options in a lease term when it is reasonably certain that we will exercise that option and when doing so is at our sole discretion. Certain equipment and vehicle leases may also include options to purchase the leased property. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise. Typically, if we decide to cancel or terminate a lease before the end of its term, then we would owe the lessor the remaining lease payments under the term of such lease. Our lease agreements generally do not contain any material residual value guarantees or material restrictive covenants. We may rent or sublease certain real estate assets that we no longer use to third parties.

Lease agreements may contain rent escalation clauses, rent holidays, or certain landlord incentives, including tenant improvement allowances. ROU assets include amounts for scheduled rent increases and are reduced by lease incentive amounts.

Certain of our lease agreements include variable rent payments consisting primarily of rental payments adjusted periodically for inflation, maintenance, and utilities. These costs are expensed as incurred. Certain of our parking arrangements also contain variable rent payments that are a percentage of parking services revenue based on contractual levels. We record contingent rent as it becomes probable that specified targets will be met. Vari able rent lease components are not included in the lease liability.

Service concession arrangements within the scope of ASU No. 2017-10, Service Concession Arrangements (Topic 853): Determining the Customer of the Operation Services, are excluded from the scope of Topic 842. Rent expenses associated with these arrangements are recorded as a reduction of revenues. See Note 4, “Revenues,” for further discussion.

Goodwill and Other Intangible Assets

Goodwill represents the excess purchase price of acquired businesses over the fair value of the assets acquired and liabilities assumed. We have elected to make the first day of our fourth quarter, August 1, the annual impairment assessment date for goodwill. However, we could be required to evaluate the recoverability of goodwill more often if impairment indicators exist. Goodwill is tested for impairment at a “reporting unit” level by performing either a qualitative evaluation or a quantitative test. The qualitative evaluation is an assessment of factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. We may elect not to perform the qualitative assessment for some or all reporting units and instead perform a quantitative test under which we estimate the fair value using a weighting of fair values derived from an income approach and a market approach. The discounted estimates of future cash flows include significant management assumptions, such as revenue growth rates, operating margins, weighted average cost of capital, and future economic and market conditions.

Other intangible assets primarily consist of acquired customer contracts and relationships that are amortized using the sum-of-the-years’-digits method over their useful lives, consistent with the estimated useful life considerations used in the determination of their fair values. This accelerated method of amortization reflects the pattern in which the economic benefits from the intangible assets of customer contracts and relationships are expected to be realized. We amortize other non-customer acquired intangibles using a straight-line method of amortization. We evaluate other intangible assets, as well as our long-lived assets, for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. When this occurs, a recoverability test is performed that compares the projected undiscounted cash flows from the use and eventual disposition of an asset or asset group to its carrying amount. If the projected undiscounted cash flows are less than the carrying amount, then we calculate an impairment loss. The impairment loss calculation compares the fair value, which is based on projected discounted cash flows, to the carrying value.

See Note 9, “Goodwill and Other Intangible Assets,” for further information on goodwill, other intangible assets, and impairment charges.

Other Noncurrent Assets

At October 31, 2024 and 2023, other noncurrent assets primarily consisted of long-term insurance recoverables, cloud computing arrangements, capitalized commissions, interest rate swap assets, prepayments to carriers for future insurance claims, and insurance deposits.

Federal Energy Savings Performance Contract Receivables

As part of our Technical Solutions business, we enter into ESPCs with the federal government pursuant to which we agree to develop, design, engineer, and construct a project and to guarantee that the project will satisfy agreed-upon performance standards. ESPC receivables represent the amount to be paid by various federal government agencies for work we have satisfactorily performed under specific ESPCs. We assign certain of our rights to receive those payments to unaffiliated third parties that provide construction financing, which we record as a liability, for such contracts. This construction financing is recorded as cash flows from financing activities, while the use of the cash received to pay project costs under these arrangements is classified as operating cash flows. The ESPC receivable is recognized as revenue as each project is constructed. Upon completion and acceptance of the project by the government and upon satisfaction of true sale criteria, the assigned ESPC receivable from the government and corresponding ESPC liability are eliminated from our consolidated financial statements.

Fair Value of Financial Instruments

Fair value is the price we would receive to sell an asset or pay to transfer a liability in an orderly transaction with a market participant at the measurement date. In the absence of active markets for identical assets or liabilities, such measurements involve developing assumptions based on market observable data and, in the absence of such data, internal information that is consistent with what market participants would use in a hypothetical transaction that occurs at the measurement date.

Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our market assumptions. Preference is given to observable inputs. These two types of inputs create the following fair value hierarchy:

Level 1– Quoted prices for identical instruments in active markets;

Level 2– Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable; and

Level 3– Significant inputs to the valuation model are unobservable.

We evaluate assets and liabilities subject to fair value measurements on a recurring and non-recurring basis to determine the appropriate level at which to classify them for each reporting period. Some non-financial assets are measured at fair value on a non-recurring basis only in certain circumstances, including the event of impairment. See Note 7, “Fair Value of Financial Instruments,” for the fair value hierarchy table and for details on how we measure fair value for our assets and liabilities.

Insurance Reserves

We use a combination of insured and self-insurance programs to cover workers’ compensation, general liability, automobile liability, property damage, and other insurable risks. Insurance claim liabilities represent our estimate of retained risks without regard to insurance coverage. We retain a substantial portion of the risk related to certain workers’ compensation and medical claims. Liabilities associated with these losses include estimates of both filed claims and IBNR Claims.

With the assistance of third-party actuaries, we review our estimate of ultimate losses for actual and IBNR Claims on a quarterly basis and adjust our required self-insurance reserves as appropriate. See Note 10, “Insurance,” for further details on the quarterly review procedures. As part of this evaluation, we review the status of existing and new claim reserves as established by third-party claims administrators. The third-party claims administrators establish the case reserves based upon known factors related to the type and severity of the claims, demographic factors, legislative matters, and case law, as appropriate. We compare actual trends to expected trends and monitor claims developments. The specific case reserves estimated by the third-party administrators are provided to an actuary who assists us in projecting an actuarial estimate of the overall ultimate losses for our self-insured or high deductible programs, which includes the case reserves plus an actuarial estimate of reserves required for additional developments, such as IBNR Claims. We utilize the results of actuarial studies to estimate our insurance rates and insurance reserves for future periods and to adjust reserves, if appropriate, for prior years.

In general, our insurance reserves are recorded on an undiscounted basis. We allocate current-year insurance expense to our operating segments based upon their underlying exposures, while actuarial adjustments related to prior year claims are recorded within Corporate expenses. We classify claims as current or long-term based on the expected settlement date. Estimated insurance recoveries related to recorded liabilities are reflected as assets in our Consolidated Balance Sheets when we believe the receipt of such amounts is probable.

Other Accrued Liabilities

At October 31, 2024 and 2023, other accrued liabilities primarily consisted of the short-term contingent consideration liability, employee benefits, contract liabilities, ESPC liabilities, unclaimed property, legal fees and settlements, and dividends payable

Other Noncurrent Liabilities

At October 31, 2024 and 2023, other noncurrent liabilities primarily consisted of the long-term contingent consideration liability, deferred compensation, long-term finance leases, and retirement plan liabilities.

Contracts with Customers

We account for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance, and collectability of consideration is probable. Once a contract is identified, we evaluate whether it is a combined or single contract and whether it should be accounted for as more than one performance obligation. Generally, most of our contracts are cancelable by either party without a substantive penalty, and the majority of our contracts have a notification period of 30 to 90 days. If a contract includes a cancellation clause, the remaining contract term is limited to the required termination notice period.

At contract inception, we assess the services promised to our customers and identify a performance obligation for each promise to transfer to the customer a service, or a bundle of services, that is distinct. To identify the performance obligation, we consider all of our services promised in the contract, regardless of whether they are explicitly stated or are implied by customary business practices.

The majority of our contracts contain multiple promises that represent an integrated bundle of services comprised of activities that may vary over time; however, these activities fulfill a single integrated performance obligation since we perform a continuous service that is substantially the same and has the same pattern of transfer to the customer. Our performance obligations are primarily satisfied over time as we provide the related services. We allocate the contract transaction price to this single performance obligation and recognize revenue as the services are performed, as further described in “Contract Types” below.

Certain arrangements involve variable consideration (primarily per transaction fees, reimbursable expenses, and sales-based royalties). We do not estimate the variable consideration for these arrangements; rather, we recognize these variable fees in the period they are earned. Some of our contracts, often related to Airline Services, may also include performance incentives based on variable performance measures that are ascertained exclusively by future performance and therefore cannot be estimated at contract inception and are recognized as revenue once known and mutually agreed upon. We include estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Our estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of our anticipated performance and all information (historical, current, and forecasted) that is reasonably available to us.

We primarily account for our performance obligations under the series guidance, using the as-invoiced practical expedient when applicable. We apply the as-invoiced practical expedient to record revenue as the services are provided, given the nature of the services provided and the frequency of billing under the customer contracts. Under this practical expedient, we recognize revenue in an amount that corresponds directly with the value to the customer of our performance completed to date and for which we have the right to invoice the customer.

We typically bill customers on a monthly basis and have the right to consideration from customers in an amount that corresponds directly with the performance obligation satisfied to date. The time between completion of the performance obligation and collection of cash is generally 30 to 60 days. Sales-based taxes are excluded from revenue.

Contracts generally can be modified to account for changes in specifications and requirements. We consider contract modifications to exist when the modification either changes the consideration, creates new performance obligations, or changes the existing scope of the contract and related performance obligations. Historically, contract modifications have been for services that are not distinct from the existing contract, since we are providing a bundle of services that are highly interrelated, and are therefore treated as if they were part of that existing contract. Such modifications are generally accounted for retrospectively as part of the existing contract.

Contract Types

We have arrangements under various contract types, as described below.

Monthly Fixed-Price

Monthly fixed-price arrangements are contracts in which the client agrees to pay a fixed fee every month over a specified contract term. We measure progress toward satisfaction of the performance obligation as the services are provided, and revenue is recognized at the agreed-upon contractual amount over time, because the customer simultaneously receives and consumes the benefits of the services as they are performed.

Square-Foot

Square-foot arrangements are contracts in which the client agrees to pay a fixed fee every month based on the actual square footage serviced over a specified contract term. We measure progress toward satisfaction of the performance obligation as the services are provided, and revenue is recognized at the agreed-upon contractual amount over time, because the customer simultaneously receives and consumes the benefits of the services as they are performed.

Cost-Plus

Cost-plus arrangements are contracts in which the clients reimburse us for the agreed-upon amount of wages and benefits, payroll taxes, insurance charges, and other expenses associated with the contracted work, plus a profit margin. We measure progress toward satisfaction of the performance obligation as the services are provided, and revenue is recognized at the agreed-upon contractual amount over time, because the customer simultaneously receives and consumes the benefits of the services as they are performed.

Work Orders

Work orders generally consist of supplemental services requested by clients outside of the standard service specification and include cleanup after tenant moves, construction cleanup, flood cleanup, and snow removal. The nature of these short-term contracts involves performing one-off type services, and revenue is recognized at the agreed-upon contractual amount over time as the services are provided, because the customer simultaneously receives and consumes the benefits of the services as they are performed.

Transaction-Price

Transaction-price contracts are arrangements in which customers are billed a fixed price for each transaction performed on a monthly basis (e.g., wheelchair passengers served, airplane cabins cleaned). We measure progress toward satisfaction of the performance obligation as the services are provided, and revenue is recognized at the agreed-upon contractual amount over time, because the customer simultaneously receives and consumes the benefits of the services as they are performed.

Hourly

Hourly arrangements are contracts in which the client is billed a fixed hourly rate for each labor hour provided. We measure progress toward satisfaction of the performance obligation as the services are provided, and revenue is recognized at the agreed-upon contractual amount over time, because the customer simultaneously receives and consumes the benefits of the services as they are performed.

Management Reimbursement

Under management reimbursement arrangements, we manage a parking facility for a management fee and pass through the revenue and expenses associated with the facility to the owner. We measure progress toward satisfaction of the performance obligation over time as the services are provided. Under these contracts we recognize both revenues and expenses, in equal amounts, that are directly reimbursed from the property owner for operating expenses, as such expenses are incurred. Such revenues do not include gross customer collections at the managed locations, because they belong to the property owners. We have determined we are the principal in these transactions, because the nature of our performance obligation is for us to provide the services on behalf of the customer and we have control of the promised services before they are transferred to the customer.

Management reimbursement revenue was $318.2 million, $302.3 million, and $280.6 million during 2024, 2023, and 2022, respectively.

Leased Location

Under leased location parking arrangements, we pay a fixed amount of rent, plus a percentage of revenues derived from monthly and transient parkers, to the property owner. We retain all revenues received, and we are responsible for most operating expenses incurred. We measure progress toward satisfaction of the performance obligation as the services are provided, and revenue is recognized over time, because the customer simultaneously receives and consumes the benefits of the services as they are performed.

Rental expense and certain other expenses under contracts that meet the definition of service concession arrangements are recorded as a reduction of revenue.

Allowance

Under allowance parking arrangements, we are paid a fixed amount or hourly rate to provide parking services, and we are responsible for certain operating expenses that are specified in the contract. We measure progress toward satisfaction of the performance obligation as the services are provided, and revenue is recognized at the agreed-upon contractual rate over time, because the customer simultaneously receives and consumes the benefits of the services as they are performed.

Energy Savings Contracts and Fixed-Price Repair and Refurbishment

Under energy savings contracts and fixed-price repair and refurbishment arrangements, we agree to develop, design, engineer, and construct a project. Additionally, as part of bundled energy solutions arrangements, we guarantee the project will satisfy agreed-upon performance standards.

We use the cost-to-cost method, which compares the actual costs incurred to date with the current estimate of total costs to complete, to measure the satisfaction of the performance obligation and recognize revenue as work progresses and we incur costs on our contracts; we believe this method best reflects the transfer of control to the customer. This measurement and comparison process requires updates to the estimate of total costs to complete the contract, and these updates may include subjective assessments and judgments. Equipment purchased for these projects is project-specific and considered a value-added element to our work. Equipment costs are incurred when the title is transferred to us, typically upon delivery to the work site. Revenue for uninstalled equipment is recognized at cost and the associated margin is deferred until installation is substantially complete.

We recognize revenue over time for all of our services as we perform them, because (i) control continuously transfers to the customer as work progresses, or (ii) we have the right to bill the customer as costs are incurred. The customer typically controls the work in process, as evidenced either by contractual termination clauses or by our rights to payment for work performed to date plus a reasonable profit to deliver products or services that do not have an alternative use to us.

Certain project contracts include a schedule of billings or invoices to the customer based on our job-to-date percentage of completion of specific tasks inherent in the fulfillment of our performance obligation(s) or in accordance with a fixed billing schedule. Fixed billing schedules may not precisely match the actual costs incurred. Therefore, revenue recognized may differ from amounts that can be billed or invoiced to the customer at any point during the contract, resulting in balances that are considered revenue recognized in excess of amounts billed or amounts billed in excess of revenue recognized. Advanced payments from our customers generally do not represent a significant financing component as the payments are used to meet working capital demands that can be higher in the early stages of a contract, as well as to protect us from our customer failing to meet its obligations under the contract.

Certain projects include service maintenance agreements under which existing systems are repaired and maintained for a specific period of time. We generally recognize revenue under these arrangements over time. Our service maintenance agreements are generallyone-year renewable agreements.

Franchise

We franchise certain engineering services through individual and area franchises under the Linc Service and TEGG brands, which are part of ABM Technical Solutions. Initial franchise fees result from the sale of a franchise license and include the use of the name, trademarks, and proprietary methods. The franchise license is considered symbolic intellectual property, and revenue related to the sale of this right is recognized at the agreed-upon contractual amount over the term of the initial franchise agreement.

Royalty fee revenue consists of sales-based royalties received as part of the consideration for the franchise right, which is calculated as a percentage of the franchisees’ revenue. We recognize royalty fee revenue at the agreed-upon contractual rates over time as the customer revenue is generated by the franchisees. A receivable is recognized for an estimate of the unreported royalty fees, which are reported and remitted to us in arrears.

Microgrid Systems and Uninterrupted Power Supply Systems Installation

We provide electrical contracting services for energy related products such as the installation of solar solutions, battery storage, distributed generation, and other specialized electric trades.

We use the cost-to-cost method, which compares the actual costs incurred to date with the current estimate of total costs to complete, to measure the satisfaction of the performance obligation and recognize revenue as work progresses and we incur costs on our contracts; we believe this method best reflects the transfer of control to the customer. This measurement and comparison process requires updates to the estimate of total costs to complete the contract, and these updates may include subjective assessments and judgments.

Certain projects include service maintenance agreements under which existing systems are repaired and maintained for a specific period of time. We generally recognize revenue under these arrangements over time. Our service maintenance agreements are generallyone-year renewable agreements.

Costs to Obtain a Contract with a Customer

We capitalize the incremental costs of obtaining a contract with a customer, primarily commissions, as contract assets and recognize the expense on a straight-line basis over a weighted average expected customer relationship period. Capitalized commissions are classified as current or noncurrent based on the timing of when we expect to recognize the expense.

Contract Balances

The timing of revenue recognition, billings, and cash collections results in contract assets and contract liabilities, as further explained below. The timing of revenue recognition may differ from the timing of invoicing to customers. If a contract includes a cancellation clause that allows for the termination of the contract by either party without a substantive penalty, then the contract term is limited to the termination notice period.

Contract assets primarily consist of billed trade receivables, unbilled trade receivables, and costs incurred in excess of amounts billed. Billed and unbilled trade receivables represent amounts from work completed in which we have an unconditional right to bill our customer. Costs incurred in excess of amounts billed typically arise when the revenue recognized on projects exceeds the amount billed to the customer. These amounts are transferred to billed trade receivables when the rights become unconditional. Contract assets also include the capitalization of incremental costs of obtaining a contract with a customer, primarily commissions.

Contract liabilities consist of deferred revenue and advance payments and billings in excess of revenue recognized. We generally classify contract liabilities as current since the related contracts are generally for a period of one year or less. Contract liabilities decrease as we recognize revenue from the satisfaction of the related performance obligation.

Advertising

Advertising costs are expensed as incurred. During 2024, 2023, and 2022, advertising expense was $10.9 million, $8.8 million, and $6.0 million, respectively.

Share-Based Compensation

Our current share-based awards principally consist of restricted stock units (“RSUs”) and performance share awards. We recognize compensation costs associated with these awards in selling, general and administrative expenses. For RSUs and performance share awards, the amount of compensation cost is measured based on the grant-date fair value of the equity instruments issued. Since our total shareholder return (“TSR”) performance share awards are performance awards with a market condition, the compensation costs associated with these awards are determined using a Monte Carlo simulation valuation model. For RSUs and TSR performance share awards, compensation cost is recognized over the period that an employee provides service in exchange for the award. We recognize compensation cost associated with other performance share awards over the requisite service period based on the probability of achievement of performance criteria.

Taxes Collected from Clients and Remitted to Governmental Agencies

We record taxes on client transactions due to governmental agencies as receivables and liabilities on the Consolidated Balance Sheets.

Net Income Per Common Share

Basic net income per common share is net income divided by the weighted-average number of common shares outstanding during the period. Diluted net income per common share is based on the weighted-average number of common shares outstanding during the period, adjusted to include the potential dilution from the conversion of RSUs, vesting of performance shares, and exercisable stock options.

Contingencies and Litigation

We are a party to a number of lawsuits, claims, and proceedings incident to the operation of our business, including those pertaining to labor and employment, contracts, personal injury, and other matters, some of which allege substantial monetary damages. Some of these actions may be brought as class actions on behalf of a class or purported class of employees. We accrue for loss contingencies when losses become probable and are reasonably estimable. If the reasonable estimate of the loss is a range and no amount within the range is a better estimate, then the minimum amount of the range is recorded as a liability. We recognize legal costs as an expense in the period incurred.

Income Taxes

We account for income taxes using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amount of existing assets and liabilities and their respective tax bases. We measure deferred tax assets and liabilities using enacted tax rates expected to be applied to taxable income in the years in which those temporary differences are expected to be recovered. Deferred tax assets are reviewed for recoverability on a quarterly basis. A valuation allowance is recorded to reduce the carrying amount of a deferred tax asset to its realizable value unless it is more likely than not that such asset will be realized. We recognize accrued interest and penalties related to unrecognized tax benefits in income tax expense in our Consolidated Statements of Comprehensive Income.

Employee Retention Tax Credit

In 2020, the U.S. government enacted the Coronavirus Aid, Relief, and Security Act (the “CARES Act”) to provide certain relief as a result of the COVID-19 Pandemic. The CARES Act provides tax relief, along with other stimulus measures, including a provision for an Employee Retention Credit (“ERC”). ERC is a refundable tax credit for employers who kept employees on their payroll during the COVID-19 Pandemic.

During the year ended October 31, 2023, we received and recorded an employee retention credit totaling $24.0 million, within the “Selling, general and administrative expenses” on our Consolidated Statements of Comprehensive Income.

Recently Adopted Accounting Standards

In September 2022, the Financial Accounting Standards Board (“FASB”) issued ASU 2022-04, Liabilities — Supplier Finance Programs (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations, designed to enhance transparency around supplier finance programs by requiring new disclosures that would allow a user of the financial statements to understand the program’s nature, activity during the period, changes from period to period, and potential magnitude. This ASU is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, except for the amendment on rollforward information, which is effective for fiscal years beginning after December 15, 2023, with early adoption permitted. We adopted this standard, effective November 1, 2023, on a prospective basis, except for the rollforward requirement, which becomes effective in fiscal year 2025. We do not participate in any material supplier finance programs and, as such, the adoption of this guidance did not have an impact on our disclosures.

Recently Issued Accounting Standards

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. This accounting update improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. This ASU requires disclosure, on an annual and interim basis, of significant segment expenses that are regularly provided to the chief operating decision maker, and an amount for other segment items by reportable segment, with a description of its composition. This ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. We are currently evaluating the impact of implementing this guidance on our financial statements.

We are currently evaluating the impact of implementing this guidance on our financial statements.

We do not expect any other recently issued accounting pronouncements to have a material impact on our consolidated financial statements and related disclosures.

3. ACQUISITIONS

Acquisition of Quality Uptime

Effective June 21, 2024, we acquired Quality Uptime Services, Inc. (“Quality Uptime”), an uninterrupted power supply system (“UPS”) installation and maintenance company providing customized preventive and emergency service programs for mission-critical data centers and other facilities, for a net cash purchase price of approximately $118.2 million (subject to customary working capital adjustments). The acquisition was accounted for under the acquisition method. Accordingly, the assets acquired and liabilities assumed were recognized on the date of acquisition at their estimated fair values, with the excess of the purchase price recorded as goodwill. The goodwill is amortizable over 15 years for income tax purposes. As of October 31, 2024, we recorded preliminary goodwill and intangibles of $80.6 million and $35.2 million, respectively. The total assets acquired, excluding goodwill and intangibles, and liabilities assumed amounted to $24.0 million and $21.6 million, respectively. The acquisition accounting is subject to change as we obtain additional information about the facts and circumstances that existed as of the acquisition date during the measurement period, not to exceed one year from the acquisition date. The final acquisition accounting may include changes to non-current assets, including intangible assets and working capital.

The Consolidated Statements of Comprehensive Income for the year ended October 31, 2024, include revenues attributable to Quality Uptime of $26.3 million. The operations of Quality Uptime are included in our Technical Solutions segment.

Acquisition of RavenVolt

On September 1, 2022, we completed the acquisition of all of the equity interests of RavenVolt, Inc. (“RavenVolt”), a nationwide provider of advanced turn-key microgrid systems utilized by diversified commercial and industrial customers, national retailers, utilities, and municipalities. RavenVolt’s operations are included within our Technical Solutions segment. The transaction met the definition of a business combination. We applied the acquisition method of accounting.

The purchase price for the acquisition was approximately $170.0 million in cash at closing (subject to customary working capital and net debt adjustments) plus the potential of post-closing contingent consideration of up to $280.0 million. The post closing contingent consideration would be payable in cash in calendar years 2024, 2025, and 2026 if RavenVolt’s earnings before interest, taxes, depreciation, and amortization (“EBITDA”), as defined in the RavenVolt merger agreement, meets or exceeds certain defined targets. The defined EBITDA targets for calendar year 2023 were not achieved, and as a result, no contingent consideration payment was made in 2024. The maximum remaining contingent consideration that is payable in calendar years 2025 and 2026 is $75.0 million, and $130.0 million, respectively. If the EBITDA achieved for calendar years 2023 - 2025 cumulatively meets the defined EBITDA targets, the entire $280.0 million would be paid in calendar year 2026, minus any earn-out payments made in 2024 and 2025.

To estimate the fair value of the contingent consideration on the date of acquisition, we used the Real Options method. The key assumptions used in our valuation were: i) forecast of revenues and EBITDA margins; ii) the volatility associated with the EBITDA; iii) risk-adjusted discount rate applied to forecasted EBITDA; and (iv) the credit-adjusted discount rate related to the payment of the contingent consideration. A simulation of one million scenarios was performed with the assistance of a third-party valuation specialist, resulting in a fair value for the cumulative contingent consideration for calendar years 2023 through 2025 totaling $59.0 million.

At October 31, 2023, the estimate of the fair value of the contingent consideration was $13.4 million. Changes in results of operations and management’s forecasts during 2024 for calendar years 2024 and 2025 were primarily due to the timing of large microgrid systems’ and generators’ installation project performing better than anticipated, resulting in a total increase of fair value to $109.1 million at October 31, 2024, of which $75.0 million relates to the calendar year 2024 payment to be made in 2025. Given the relatively short period of time until the end of the earn-out period, there is a high level of confidence in the projections for calendar year 2024 that are the basis for the estimated contingent consideration payment. This change in the fair value is recognized within the “Selling, general and administrative expenses” of the Consolidated Statements of Comprehensive Income.

4. REVENUES

Disaggregation of Revenues

We generate revenues under several types of contracts, which are further described in Note 2, “Basis of Presentation and Significant Accounting Policies.” Generally, the type of contract is determined by the nature of the services provided by each of our major service lines throughout our reportable segments; therefore, we disaggregate revenues from contracts with customers into major service lines. We have determined that disaggregating revenues into these categories best depicts how the nature, amount, timing, and uncertainty of revenues and cash flows are affected by economic factors. Our reportable segments are B&I, M&D, Education, Aviation, and Technical Solutions, as described in Note 17, “Segment and Geographic Information.”

(1) Janitorial arrangements provide a wide range of essential cleaning services for commercial office buildings, airports and other transportation centers, educational institutions, government buildings, health facilities, industrial buildings, retail stores, and stadiums and arenas. These arrangements are often structured as monthly fixed-price, square-foot, cost-plus, and work order contracts.

(2) Parking arrangements provide parking and transportation services for clients at various locations, including airports and other transportation centers, commercial office buildings, educational institutions, health facilities, hotels, and stadiums and arenas. These arrangements are structured as management reimbursement, leased location, and allowance contracts. Certain of these arrangements are considered service concession agreements and are accounted for under the guidance of Topic 853; accordingly, rent expense related to these arrangements is recorded as a reduction of the related parking service revenues.

(3) Facility Services arrangements provide onsite mechanical engineering and technical services and solutions relating to a broad range of facilities and infrastructure systems that are designed to extend the useful life of facility fixed assets, improve equipment operating efficiencies, reduce energy consumption, lower overall operational costs for clients, and enhance the sustainability of client locations. These arrangements are generally structured as monthly fixed-price, cost-plus, and work order contracts.

(4) Building & Energy Solutions arrangements provide custom energy solutions, including microgrid systems installation, electrical, HVAC, lighting, electric vehicle charging station installation, uninterrupted power supply services, and other general maintenance and repair services for clients in the public and private sectors and are generally structured as Energy Savings, Fixed-Price Repair, and Refurbishment contracts. We also franchise certain operations under franchise agreements relating to our Linc Network and TEGG brands pursuant to franchise contracts.

(5) Airline Services arrangements support airlines and airports with services such as passenger assistance, catering logistics, and airplane cabin maintenance. These arrangements are often structured as monthly fixed-price, cost-plus, transaction price, and hourly contracts.

Remaining Performance Obligations

At October 31, 2024, performance obligations that were unsatisfied or partially unsatisfied for which we expect to recognize revenue totaled $258.7 million. We expect to recognize revenue on approximately 71% of the remaining performance obligations over the next 12 months, with the remainder recognized thereafter, based on our estimates of project timing.

These amounts exclude variable consideration primarily related to: (i) contracts where we have determined that the contract consists of a series of distinct service periods and revenues are based on future performance that cannot be estimated at contract inception; (ii) parking contracts where we and the customer share the gross revenues or operating profit for the location; and (iii) contracts where transaction prices include performance incentives that are based on future performance and therefore cannot be estimated at contract inception. We apply the practical expedient that permits exclusion of information about the remaining performance obligations with original expected durations of one year or less.

Contract Balances

The following tables present the balances in our contract assets and contract liabilities:

(1) Included in “Trade accounts receivable, net” on the Consolidated Balance Sheets. The fluctuations correlate directly to the execution of new customer contracts and to invoicing and collections from customers in the normal course of business.

(2) Fluctuation is primarily due to the timing of payments on our contracts measured using the cost-to-cost method of revenue recognition.

(3) Included in “Other current assets” and “Other noncurrent assets” on the Consolidated Balance Sheets. During the year ended October 31, 2024, we capitalized $16.1 million of new costs and amortized $15.5 million of previously capitalized costs. There wasno impairment loss recorded on the costs capitalized.

(1) Included in other accrued liabilities on the Consolidated Balance Sheets.

(2) Represents additions associated with the Quality Uptime Acquisition.

5. LEASES

The components of lease assets and liabilities and their classification on our Consolidated Balance Sheets were as follows:

(1) Finance lease assets are recorded net of accumulated amortization of $23.1 million and $18.9 million as of October 31, 2024 and October 31, 2023, respectively.

The components of lease costs and classification within the Consolidated Statements of Comprehensive Income were as follows:

(1) Related to certain parking arrangements.

(2) Includes short-term lease costs and variable lease costs.

(3) Includes short-term lease costs.

(4) Represents amortization of leased assets.

(5) Interest on lease liabilities.

The following table presents information on short-term and variable lease costs:

Sublease income generated during the year ended October 31, 2024, was immaterial.

The amounts of future undiscounted cash flows related to the lease payments over the lease terms and the reconciliation to the present value of the lease liabilities as recorded on our Consolidated Balance Sheets as of October 31, 2024, are as follows:

Future sublease rental income was excluded for the periods shown above as the amounts are immaterial.

We have entered into operating lease arrangements as of October 31, 2024, that are effective for future periods. The total amount of ROU assets and lease liabilities related to these arrangements is immaterial.

The following table includes the weighted-average remaining lease terms, in years, and the weighted-average discount rate used to calculate the present value of operating lease liabilities:

The following table includes supplemental cash and non-cash information related to operating leases:

7. FAIR VALUE OF FINANCIAL INSTRUMENTS

Fair Value Hierarchy of Our Financial Instruments

Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis

(1) Cash and cash equivalents are stated at nominal value, which equals fair value.

(2) Represents restricted deposits that are used to collateralize our insurance obligations and are stated at nominal value, which equals fair value. These insurance deposits are included in “Other noncurrent assets” on the accompanying Consolidated Balance Sheets. See Note 10, “Insurance,” for further information.

(3) Represents investments held in Rabbi trusts associated with one of our deferred compensation plans, which we include in “Other noncurrent assets” on the accompanying Consolidated Balance Sheets. The fair value of the assets held in the funded deferred compensation plan is based on quoted market prices. See Note 12, “Employee Benefit Plans,” for further information.

(4) Represents gross outstanding borrowings under our Amended Credit Facility. Due to variable interest rates, the carrying value of outstanding borrowings under our line of credit and term loan approximates the fair value. See Note 11, “Credit Facility,” for further information.

(5) Represents interest rate swap derivatives designated as cash flow hedges. The fair values of the interest rate swaps are estimated based on the present value of the difference between expected cash flows calculated at the contracted interest rates and the expected cash flows at current market interest rates using observable benchmarks for the Secured Overnight Financing Rate (“SOFR”) forward rates at the end of the period. At October 31, 2024 and 2023, our interest rate swap assets are included in “Other noncurrent assets” on the accompanying Consolidated Balance Sheets. See Note 11, “Credit Facility,” for further information.

(6 Our investments do not have a readily determinable fair value; therefore, we account for the investments using the measurement alternative under Topic 321 and measure the investments at initial cost plus or minus fair value adjustments if there are observable prices minus impairment, if any.

(7) At October 31, 2024, our contingent consideration payable related to the RavenVolt Acquisition is recorded at fair value as a liability on the acquisition date and is remeasured at each reporting date, based on significant inputs not observable in the market, which represents a Level 3 measurement within the fair value hierarchy. After the acquisition date and until the contingency is resolved, the fair value of contingent consideration payable is adjusted each reporting period based primarily on the expected probability of achievement of the contingency targets which are subject to our estimate. These changes in fair value are recognized within “Selling, general and administrative expenses” of the Consolidated Statements of Comprehensive Income. See Note 3, “Acquisitions,” for further information.

There were no transfers to or from Level 3 financial assets or liabilities during 2024 and 2023. At October 31, 2024 and 2023, the Company had no financial assets recorded at fair value using Level 3 inputs.

Non-Financial Assets Measured at Fair Value on a Non-Recurring Basis

In addition to assets and liabilities that are measured at fair value on a recurring basis, we are also required to measure certain items at fair value on a non-recurring basis. These assets can include: goodwill; intangible assets; property, plant and equipment; lease-related ROU assets; and long-lived assets that have been reduced to fair value when they are held for sale. If certain triggering events occur or if an annual impairment test is required, we would evaluate these non-financial assets for impairment. If an impairment were to occur, the asset would be recorded at the estimated fair value, using primarily unobservable Level 3 inputs.

8. PROPERTY, PLANT AND EQUIPMENT

Property, Plant and Equipment

(1) For 2024, 2023, and 2022, depreciation expense was $50.5 million, $44.2 million, and $40.3 million, respectively.

9. GOODWILL AND OTHER INTANGIBLE ASSETS

Goodwill

(1) During 2024, goodwill increased primarily as a result of the Quality Uptime Acquisition. See Note 3, “Acquisitions”, for additional information.

We didnot record goodwill impairment charges during fiscal years 2024 and 2023.

Other Intangible Assets

(1)These intangible assets are being amortized over the expected period of benefit, with a weighted average life of approximately 11 years.

Estimated Annual Amortization Expense for Each of the Next Five Years

(1) These amounts could vary as acquisitions of additional intangible assets occur in the future and as acquisition accounting is finalized for existing acquisitions.

The estimates of future cash flows used in determining the fair value of goodwill and other intangible assets involve significant management judgment and are based upon assumptions about expected future operating performance, economic conditions, market conditions, and cost of capital. Inherent in estimating the future cash flows are uncertainties beyond our control, such as changes in capital markets. The actual cash flows could differ materially from management’s estimates due to changes in business conditions, operating performance, and economic conditions.

10. INSURANCE

We use a combination of insured and self-insurance programs to cover workers’ compensation, general liability, automobile liability, property damage, and other insurable risks. For the majority of these insurance programs, we retain the initial $1.0 million to $1.5 million of exposure on a per-occurrence basis, either through deductibles or self-insured retentions. Beginning November 1, 2023, retentions range between $1.0 million and $5.0 million of exposure on a per-occurrence basis. Beyond the retained exposures, we have varying primary policy limits ranging between $1.0 million and $5.0 million per occurrence. To cover general liability and automobile liability losses above these primary limits, we maintain commercial umbrella insurance policies that provide aggregate limits of $200.0 million. Our insurance policies generally cover workers’ compensation losses to the full extent of statutory requirements. Additionally, to cover property damage risks above our retained limits, we maintain policies that provide per occurrence limits of $75.0 million. We are also self-insured for certain employee medical and dental plans. We maintain stop-loss insurance for our self-insured medical plan under which we retain up to $0.5 million of exposure on a per-participant, per-year basis with respect to claims.

We maintain our reserves for workers’ compensation, general liability, automobile liability, and property damage insurance claims based upon known trends and events and the actuarial estimates of required reserves considering the most recently completed actuarial reports. We use all available information to develop our best estimate of insurance claims reserves as information is obtained. The results of actuarial reviews are used to estimate our insurance rates and insurance reserves for future periods and to adjust reserves, if appropriate, for prior years.

Insurance Reserve Adjustments

Actuarial Reviews and Updates Performed During 2024

We review our self-insurance liabilities on a quarterly basis and adjust our accruals accordingly. Actual claims activity or development may vary from our assumptions and estimates, which may result in material losses or gains. As we obtain additional information that affects the assumptions and estimates used in our reserve liability calculations, we adjust our self-insurance rates and reserves for future periods and, if appropriate, adjust our reserves for claims incurred in prior accounting periods.

During the first and third quarters of 2024, we performed comprehensive actuarial reviews of the majority of our casualty insurance programs to evaluate changes made to claims reserves and claims payment activity for the periods of May 1, 2023, through October 31, 2023, and November 1, 2023, through April 30, 2024, respectively (the “Actuarial Reviews”). The Actuarial Reviews were comprehensive in nature and were based on loss development patterns, trend assumptions, and underlying expected loss costs during the periods analyzed.

During the second and fourth quarters of 2024, we performed interim actuarial updates of the majority of our casualty insurance programs that considered changes in claims development and claims payment activity for the respective periods analyzed (the “Interim Updates”). These Interim Updates were abbreviated in nature based on actual versus expected development during the periods analyzed and relied on the key assumptions in the Actuarial Reviews (most notably loss development patterns, trend assumptions, and underlying expected loss costs).

Based on the results of the Actuarial Reviews and Interim Updates, we increased our total reserves related to prior years for known claims as well as our estimate of the loss amounts associated with IBNR Claims during 2024 by $20.3 million. The adverse development was offset by improvements in other legacy programs. In 2023, we decreased our total reserves related to prior year claims by $14.8 million.

Insurance-Related Balances and Activity

At October 31, 2024 and 2023, insurance recoverables are included in both “Other current assets” and “Other noncurrent assets” on the accompanying Consolidated Balance Sheets.

Casualty Program Insurance Reserves Rollforward

(1) Includes reserves related to discontinued operations of approximately $0.7 million for 2024, $0.1 million for 2023, and $0.2 million for 2022.
