The Company’s accounting for revenues is governed by two accounting standards. The majority of the Company’s revenues are considered lease or lease related and are accounted for in accordance with Accounting Standards Codification 842, Leases (Topic 842). Revenues determined to be non-lease related are accounted for in accordance with ASC 606, Revenue from Contracts with Customers (Topic 606). The Company accounts for revenues when approval and commitment from both parties have been obtained, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. The Company typically recognizes non-lease related revenues at a point in time because the customer does not simultaneously consume the benefits of the Company’s promised goods and services, or performance obligations, and obtains control when delivery and installation are complete. For contracts that have multiple performance obligations, the transaction price is allocated to each performance obligation in the contract based on the Company’s best estimate of the standalone selling prices of each distinct performance obligation in the contract. The standalone selling price is typically determined based upon the expected cost plus an estimated margin of each performance obligation.

Revenue from contracts that satisfy the criteria for over time recognition are recognized as work is performed by using the ratio of costs incurred to estimated total contract costs for each contract. The majority of revenue for these contracts is derived from long-term projects which typically span multiple quarters. The timing of revenue recognition, billings, and cash collections results in billed contract receivables and contract assets on the Company's Consolidated Balance Sheets. In the Company’s contracts, amounts are billed as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals or upon achievement of contractual milestones. Billings can occur subsequent to revenue recognition, resulting in contract assets, or in advance, resulting in contract liabilities. These contract assets and liabilities are reported on the Consolidated Balance Sheets on a contract-by-contract basis at the end of each reporting period. The contract liabilities included in Deferred income on the Company’s Consolidated Balance Sheets totaled $49.1 million and $40.7 million at September 30, 2024 and December 31, 2023, respectively. Sales revenues totaling $10.6 million and $26.3 million were recognized during the three and nine months ended September 30, 2024, respectively, which were included in the contract liability balance at December 31, 2023. For certain modular building sales, the customer retains a small portion of the contract price until full completion of the contract, or revenue is recognizable prior to customer billing, which results in revenue earned in excess of billings. These unbilled contract assets are included in Accounts receivable on the Company’s Consolidated Balance Sheets and totaled $16.7 million and $8.7 million at September 30, 2024 and December 31, 2023, respectively. The Company did not recognize any material contract asset impairments during the periods ended September 30, 2024 and December 31, 2023, respectively.

The Company's uncompleted contracts with customers which meet the criteria for over-time revenue recognition have unsatisfied or partially satisfied performance obligations. As of September 30, 2024, approximately $67.1 million of revenue is expected to be recognized for unsatisfied or partially satisfied obligations. The Company expects to recognize revenue for approximately one half of

these unsatisfied or partially satisfied performance obligations over the next 12 months, with the remaining balance recognized thereafter. For the three and nine months ended September 30, 2024, approximately $96.9 million and $198.9 million of revenue was recognized for sales and non-lease services transferred at a point in time, respectively, and approximately $16.6 million and $28.2 million of revenue was recognized for sales and non-lease services transferred over time, respectively.

The Company generally rents and sells to customers on 30 day payment terms. The Company does not typically offer variable payment terms or accept non-monetary consideration. Amounts billed and due from the Company’s customers are classified as Accounts receivable on the Company’s consolidated balance sheet. For certain sales of modular buildings, progress payments from the customer are received during the manufacturing of new equipment, or the preparation of used equipment. The advance payments are not considered a significant financing component because the payments are used to meet working capital needs during the contract and to protect the Company from the customer failing to adequately complete their obligations under the contract.

Rental revenues from operating leases are recognized on a straight-line basis over the term of the lease for all operating segments. Rental billings for periods extending beyond period end are recorded as deferred income and are recognized in the period earned. Rental related services revenues are primarily associated with relocatable modular buildings. For modular building leases, rental related services revenues for modifications, delivery, installation, dismantle and return delivery are lease related because the payments are considered minimum lease payments that are an integral part of the negotiated lease agreement with the customer. These revenues are recognized on a straight-line basis over the term of the lease. Certain leases are accounted for as finance leases. For these leases, sales revenue and the related accounts receivable are recognized upon delivery and installation of the equipment and the unearned interest is recognized over the lease term on a basis which results in a constant rate of return on the unrecovered lease investment. As of the nine months ended September 30, 2024, the Company’s future minimum lease payments to be received under non-cancelable finance leases were $2.4 million. Of the total investment in sales-type leases, future minimum lease payments are expected to be $1.7 million in 2025, $0.5 million in 2026, and $0.2 million in 2027. The Company’s assessment of current expected losses on these receivables was immaterial and therefore no credit loss expense was provided as of the nine months ended September 30, 2024. Other revenues include interest income on finance leases and rental income on facility leases.

In the three and nine months ended September 30, 2024, the Company’s lease revenues were $153.3 million and $440.1 million, respectively, consisting of $152.7 million and $438.5 million of operating lease revenues, respectively, and $0.5 million and $1.6 million of finance lease revenues, respectively. The Company has entered into finance leases to finance certain equipment sales to customers. The lease agreements have a bargain purchase option at the end of the lease term. For these leases, sales revenue and the related accounts receivable are recognized upon delivery and installation of the equipment and the unearned interest is recognized over the lease term on a straight-line basis, which results in a constant rate of return on the unrecovered lease investment. The Company’s finance lease revenues for the three and nine months ended September 30, 2024 include $0.4 million and $1.3 million of sales revenues, respectively, and $0.1 million and $0.3 million of interest income, respectively.

Non-lease revenues are recognized in the period when control of the performance obligation is transferred, in an amount that reflects the consideration the Company expects to be entitled to receive in exchange for those goods or services. For portable storage containers and electronic test equipment, rental related services revenues for delivery and return delivery are considered non-lease revenues.

Sales revenues are typically recognized at a point in time, which occurs upon the completion of delivery, installation and acceptance of the equipment by the customer. Accounting for non-lease revenues requires judgment in determining the point in time the customer gains control of the equipment and the appropriate accounting period to recognize revenue.

Sales taxes charged to customers are reported on a net basis and are excluded from revenues and expenses.

Customer returns of rental equipment prior to the end of the rental contract term are typically billed a cancellation fee, which is recorded as rental revenue in the period billed. Sales of new relocatable modular buildings, portable storage containers and electronic test equipment not manufactured by the Company are typically covered by warranties provided by the manufacturer of the products sold. The Company typically provides limited 90-day warranties for certain sales of used rental equipment and one-year warranties on equipment manufactured by Enviroplex. Although the Company’s policy is to provide reserves for warranties when required for specific circumstances, warranty costs have not been significant to date.

The Company’s incremental cost of obtaining lease contracts, which consists of salesperson commissions, are deferred and amortized over the initial lease term for modular leases. Incremental costs for obtaining a contract for all other operating segments are expensed in the period incurred because the lease term is typically less than 12 months.

Other income, net consists of the net gain on sales of property, plant and equipment. These sales are generally recognized at a point in time, with contractually defined performance obligations that are typically transferred upon the closing date of the sale. These

types of sales are infrequent in occurrence and reported on the condensed consolidated statements of income within the scope of ASC 610, Other Income. Proceeds to be received from the sale of property, plant and equipment are included in Accounts receivable on the Company's condensed consolidated balance sheets.
